This guide shows exactly how to enable each maker’s mode, what each mode does, and simple checks to do before and after the wash. Tech9AutoRepair’s James Walker offers hands-on tips throughout to help prevent paint damage and water-related issues.
Follow the clear steps and best practices here to save time, avoid repair bills, and keep the vehicle’s finish and seals in good shape.
Key Takeaways
- Activate each car’s wash mode to lock moving parts and prevent damage.
- Check seals, charge port, and wipers before entering any automated wash.
- Use recommended washing methods and post-wash checks to protect paint and electronics.
Essential Safety Precautions
Follow specific prep steps, protect cameras and sensors, and keep water away from vulnerable electronics. These actions prevent false sensor triggers, stuck doors, and costly repairs.
Preparing Your EV Before Washing
They must set the car into the correct wash mode first — Tesla uses Car Wash Mode; Rivian has a similar wash or transport mode. Confirm the vehicle shows the active wash state on the main screen before moving to the wash bay.
They should fold mirrors, lock the charge port, and secure any loose trim or aftermarket accessories. Remove or tape down antennae, roof racks, and magnetic mounts. For Teslas, enable “Enable Free Roll” or shift to Neutral if the wash requires it; follow Rivian prompts for Neutral or free-rolling settings.
They must disable automatic wipers, scheduled climate, and walk‑away locking to stop sudden movements. Keep the key fob or phone app with the attendant only if the manufacturer allows remote control during the wash. Always check tire pressure and parking brake status before entering an automated conveyor.
Protecting Sensors and Cameras
They should avoid pressure washers directly on cameras and ultrasonic sensors. High-pressure streams can dislodge seals or fog lenses, causing long-term sensor errors.
Use car wash mode to put sensors into a passive state. If the mode doesn’t explicitly disable all parking sensors, cover fragile sensors with temporary tape approved for paint. Wipe lenses gently with a microfiber cloth before the wash to remove grit that could scratch during contact washes.
Inspect camera housings and sensor seams after washing. If the vehicle shows sensor faults on the dash, park in a dry spot and reboot the infotainment system or power cycle per the owner manual before driving.
Avoiding Water Damage to Electronics
They must keep water out of charging ports, speaker grilles, and underbody junction boxes. Never aim hoses directly into seams or open ports.
Use the vehicle’s recommended steps for sealed ports: close charge doors, remove charging cables, and ensure all drain holes are clear. For Rivian and Tesla, verify door seals and window seals are intact; replace any cracked weatherstripping before a wash.
If the car shows wet‑related warnings after washing (e.g., CAN bus or ECU alerts), dry affected areas and run vehicle diagnostics. Persistent electronic faults require dealer or certified technician inspection to prevent hidden water ingress.
| Item | Action | Why it matters |
| Car Wash Mode / Neutral | Activate per vehicle prompts | Prevents brakes and wipers from engaging |
| Fold Mirrors & Secure Accessories | Fold or remove before wash | Reduces risk of breakage and scratches |
| Sensors & Cameras | Cover or avoid direct spray; use wash mode | Prevents sensor faults and lens damage |
| Charge Port & Electronics | Close ports; dry seals after wash | Avoids corrosion and electrical faults |
Activating Car Wash Mode on Tesla
Car Wash Mode secures windows, locks the charge port, parks the mirrors, and limits automatic systems that could interfere with a wash. The steps below show exactly where to tap, which options to set, and how to exit the mode when finished.
Step-by-Step Activation Process
Tap the car icon on the touchscreen to open Controls, then select the “Service” menu. In Service, choose “Car Wash Mode.”
If the software differs, use the quick-search bar on the touchscreen and type “Car Wash” to jump to the setting.
After selecting Car Wash Mode, the car confirms it will: lock charge port, disable automatic wipers, keep doors locked, and fold mirrors. For conveyor car washes, also enable “Free Roll” if available so the car won’t apply brakes when the conveyor moves it.
Make sure all doors, windows, and the trunk are closed before starting the wash. Verify the sunroof is fully closed on vehicles that have one. Walk around and visually confirm mirrors are folded and the charge port light is off.
Customizable Options and Settings
Tesla offers a few toggleable options inside Car Wash Mode. Typical options include: free roll (for conveyor washes), lock charge port, and disable automatic wipers. Not every model shows the same list, so check the on-screen options for your vehicle.
Use the following table to compare common options and when to enable them:
| Option | What it does | When to enable |
|---|---|---|
| Free Roll | Prevents brakes from engaging so conveyor moves car | Automatic conveyor car wash |
| Lock Charge Port | Prevents charge cable from opening or moving | Always for public or automatic washes |
| Disable Wipers | Stops wipers from running during wash | Any automatic or high-pressure wash |
If a user relies on mobile app controls, confirm the car remains unlocked in the app and that the Tesla app shows Car Wash Mode active. Some models display status on the instrument cluster; others show it only on the center screen.
Deactivating Car Wash Mode After Use
Car Wash Mode turns off automatically if the vehicle moves faster than 9 mph (15 km/h). The driver can also tap “Exit” on the touchscreen to leave the mode manually.
After the wash, check the touchscreen to confirm Car Wash Mode is off. Physically inspect the car: mirrors should return to normal, charge port should unlock if the setting allows, and wipers should function again.
If any feature does not revert, a quick vehicle reboot (hold both scroll wheels until the screen resets) usually fixes it. For persistent issues, contact Tesla Service and report which settings failed to restore.
Using Car Wash Mode on Rivian
Car Wash Mode secures doors, mirrors, and charging hardware, and disables some sensors to prevent false alerts. It takes seconds to enable from the touchscreen and should be turned on before any automated wash.
Accessing Car Wash Mode in the Interface
They open the central touchscreen to start. Tap Settings > Access & Security > Car Wash. The option appears as a toggle; enabling it shows a confirmation and updates the mobile app status after a few seconds.
If the vehicle is locked, some Rivian models require the doors to be unlocked to change the setting. Neutral or Park is recommended before using the wash, depending on the wash type. If the mode seems missing, check for a software update or consult the in-vehicle help menu.
Adjusting Lock and Mirror Settings
Car Wash Mode automatically folds mirrors and locks the charge port on many Rivian models. They can verify or override these behaviors in the same Access & Security menu before starting the wash.
Use this quick table to confirm what toggles to check:
| Feature | Typical Car Wash Mode Action | User Control |
|---|---|---|
| Side mirrors | Fold in | Can manually fold/unfold from Controls |
| Charge port | Lock/disable | Toggle in Access & Security |
| Wipers | Park/disable | Set from Wiper menu if needed |
They should also check door locks and window status. Manually close any open windows or the tailgate if the car didn’t do it. Confirm camera and sensor warnings are silenced to avoid alarms during the wash.
Exiting Car Wash Mode Securely
After the wash, they return to the touchscreen to turn Car Wash Mode off the same way it was enabled. Tap Settings > Access & Security > Car Wash and toggle off.
They should visually confirm mirrors are unfolded and the charge port is unlocked before driving away. If the vehicle stays in Neutral or shows an error, shift to Park and restart the system if needed. Finally, check the app to ensure the vehicle status matches the car’s physical state.
Comparing Features: Tesla vs. Rivian
Both systems lock doors, disable windshield wipers, and lower mirrors automatically. They also pause charging and adjust certain sensors to prevent false triggers during an automated car wash.
Differences in User Experience
Tesla hides Car Wash Mode inside the main controls and the mobile app. Activating it typically locks the charge port, closes windows, and turns off Sentry and walk‑away locking. The interface shows a simple status icon and a clear on/off toggle, so drivers can confirm the car is ready before entering the wash.
Rivian places its Car Wash Mode in vehicle settings and the app too, but adds an on‑screen checklist that prompts the driver to stow the gear tunnel and secure the frunk if present. Rivian’s prompts tend to be more verbose, walking owners through each step. Both brands offer app notifications when mode engages or exits, but Tesla’s feedback is more minimal while Rivian gives step‑by‑step confirmations.
Unique Capabilities of Each System
| Feature | Tesla | Rivian |
|---|---|---|
| Mirror fold | Automatic on most models | Automatic, with on‑screen reminder |
| Sensors / Autopilot pause | Disables Autopilot and parking sensors | Disables driver assistance and mutes sensor alerts |
| App feedback | Simple status icon and notification | Checklist + confirmation alerts |
| Tailored prompts | Minimal prompts, quick toggle | Stepwise checklist for storage compartments |
Tesla focuses on a fast, minimal interaction that gets the car ready with one toggle. Rivian emphasizes guided checks and visible confirmations to ensure no loose items or open compartments remain.
Best Practices for Touchless and Tunnel Washes
Choose a wash that avoids brushes and secures moving parts. Prepare the vehicle by locking or disabling any retractable handles, charge doors, and automatic wipers. Check each wash’s conveyor type and speed before you enter.
Recommended Wash Types for Electric Vehicles
Touchless washes are the safest option for most EVs because they use high-pressure water and detergents without brushes that can catch retractable handles or trim. Look for a touchless wash that lists compatibility with electric vehicles and offers a “soft” or “low-pressure” setting for nozzles near mirrors and cameras.
If using a tunnel wash with a conveyor, pick one with a free-roll or neutral-drive option so the car’s parking brake and auto-hold aren’t fighting the conveyor. Avoid brush-style or old automatic washes with visible wear on cloths or rotating arms. For more context about wash types and risks, see this overview on car wash systems.
Select Features to Enable or Disable
Before entering, enable Car Wash Mode (Tesla) or Wash Mode (Rivian) to lock windows, fold mirrors, disable automatic wipers, and lock the charge port. On a Tesla, also enable “Free Roll” if available so the car won’t apply regenerative braking or auto-hold during conveyor movement.
Disable automatic door handles on models that retract, and manually fold mirrors if the system doesn’t do it. Turn off valet or passive entry features that could unlock the car if a keyfob gets close. Confirm cameras and ultrasonic sensors won’t trigger the wash equipment; if unsure, cover or retract fragile sensors per the owner manual. For technical details on vehicle modes, check the manufacturer’s support pages or trusted guides like this Rivian wash guide linked in owner resources.
Maintaining Vehicle Condition Post-Wash
Check fixed parts, seals, and paint for water traps, paper bits, or wheel cleaner residue. Dry sensitive areas and verify moving parts work before driving. Follow these steps to keep seals, sensors, and finishes in good shape.
Routine Checks After Car Washing
They should open doors, trunk, and charge port to confirm latches and seals fully close. Inspect rubber door and trunk seals for trapped water or debris; wipe them with a microfiber towel and apply a small amount of silicone lubricant if seals feel sticky. Check retractable handles and mirrors on both Tesla and Rivian to ensure they extend and retract smoothly.
They must verify windshield wipers park correctly and that washer nozzles are clear. Look under wheel arches for wheel-cleaner residue that can corrode metal or trim. Finally, run the car’s diagnostics screen (if available) to confirm no sensors report faults after the wash.
Preventing Residue and Streaks
They should dry painted surfaces within 10–15 minutes after exiting a wash to avoid mineral spots. Use a clean microfiber towel and blot first, then wipe in one direction to reduce streaking. For glass, use a glass-specific microfiber and, if needed, a small amount of isopropyl-based cleaner to remove streaks without damaging coatings.
Pay attention to trim and plastic; automotive detail spray can remove soap film and restore finish without heavy rubbing. For hard-to-reach gaps, compressed air or a soft-bristled brush will remove trapped debris. For more on water-spot chemistry and prevention, readers can consult general water treatment information like hard water, and for best drying tools consider guidance from specialty care sources such as the Specialty Coffee Association on microfiber care and handling.
Troubleshooting Common Issues
If Car Wash Mode won’t engage, check that the vehicle is in Park and the touchscreen software is up to date. A quick reboot of the infotainment system often clears minor bugs. If the problem persists, restart the car by powering off from Controls > Safety & Security.
Sometimes the car stays stuck in Car Wash Mode after the wash. They should try exiting the mode from the same menu first. If that fails, unlocking and locking the doors or cycling power can restore normal functions like wipers and charging port release.
If mirrors won’t fold or windows won’t operate, confirm any child locks or manual lock switches are off. Physical obstructions or ice can also prevent mechanical movement. Inspect components briefly and remove debris before forcing anything.
When automatic wipers or sensors misbehave, they may need recalibration. Sensor dirt, soap residue, or heavy water on cameras can cause false triggers. Cleaning camera and sensor housings often fixes inconsistent behavior.
If the charging port stays closed, a firmware glitch or electrical fault might be the cause. Try a soft reset and, if needed, open the port manually following the owner’s manual. Contact service if the port still won’t release.
For persistent problems, gather error messages, screenshots, and the vehicle VIN before contacting support. This speeds diagnosis and helps technicians resolve issues more efficiently.
