Quick Answer: To use car wash mode on Tesla and Rivian, open the touchscreen menu (Tesla: Controls or Service; Rivian: Access and Security), select Car Wash Mode, confirm the prompt, and shift into neutral if using an automatic conveyor wash. This closes windows, locks the charge port, and disables wipers and sensors so the wash goes smoothly.
Electric vehicles pack in cameras, ultrasonic sensors, rain-sensing wipers, and motorized doors and charge ports — all things that can get confused by soap, brushes, and high-pressure water. That is exactly why learning how to use car wash mode on Tesla and Rivian vehicles matters before your next trip through the tunnel. In my testing experience going through both automatic and touchless washes, activating this feature ahead of time is the difference between a relaxed wash and a dashboard full of warning messages.

What Is Car Wash Mode on Tesla and Rivian?
Car wash mode on Tesla and Rivian is a built-in software setting that temporarily changes how the vehicle behaves so it can pass through a wash without triggering false alarms or unwanted movements. Instead of manually turning off half a dozen features one at a time, you tap a single menu item and the car handles the rest.
On Tesla vehicles, this feature closes the windows, locks the charge port, disables the rain-sensing wipers, mutes parking sensor chimes, and turns off Sentry Mode and walk-away door locking. Many Tesla models also offer an “Enable Free Roll” option that shifts the car into neutral so it can be pulled through a conveyor without the motors resisting. Rivian’s version works on a similar idea. It is generally found under the touchscreen’s Access and Security menu, and it helps mute parking sensors, disable proximity locking, turn off automatic emergency braking, and shift into neutral for a rollerless conveyor wash.
Menu wording and exact steps change from one software version to the next on both brands, so treat the paths in this guide as a starting point and always confirm the exact wording on your own screen before you start.
Why Car Wash Mode Matters for Your EV
A modern EV is essentially a rolling computer covered in sensors. Ultrasonic parking sensors, cameras, and rain sensors are designed to react to things touching or approaching the car — which is precisely what happens during a wash. Without car wash mode active, a Tesla or Rivian may interpret spinning brushes as an obstacle, mistake spray water for rain, or try to reopen a charge port that a brush has bumped.
Understanding how to use car wash mode on Tesla and Rivian vehicles is not just a nice-to-have convenience. Some owners have reported that damage caused by skipping this step, such as a wiper motor strain or a charge port malfunction, is not automatically covered under vehicle warranty, since it stems from the wash environment rather than a manufacturing defect. Checking your own vehicle’s warranty terms is the safest way to know exactly what is and is not covered in your case.
Note: Car wash mode is a software convenience feature, not a certified safety system. It can help reduce the chance of accidental triggers during a wash, but it does not guarantee the vehicle will be free of cosmetic or mechanical issues afterward.
Tesla vs Rivian: How the Feature Compares
While both brands built car wash mode to solve the same basic problem, the details differ enough that it helps to see them side by side before your next wash.
How Car Wash Mode Works, in Plain English
Both Tesla and Rivian rely on a 12-volt low-voltage system, similar to a conventional car, to run accessories like door locks, sensors, and infotainment, while the high-voltage battery pack handles propulsion. Car wash mode does not touch the high-voltage system. It simply sends a batch of commands to the 12-volt controlled features, telling them to go into a temporary “hands off” state until you exit the mode or drive away.
This matters for owners in every market, since the underlying idea is the same everywhere the vehicles are sold: a temporary software state, not a hardware change, protects moving parts like wipers and the charge port flap from reacting to water and brushes.
Using car wash mode on Tesla and Rivian vehicles is available whether the car is brand new or has been driven for years, as long as the software has received the update that introduced the feature. Owners of older software versions may need to check for a pending update before the option appears on their screen.

Practical takeaway: the flow is nearly identical for both brands. Missing step 2 or 5 is where most first-time issues happen.
Step-by-Step: How to Turn On Car Wash Mode on Tesla and Rivian
Here is a general walkthrough that applies to most current Tesla and Rivian software versions. Menu names may look slightly different depending on your model and update, so use this as a guide rather than an exact script.
Tip: Activate car wash mode while you are still waiting in line. It only takes a few seconds, and doing it early means you are not fumbling through menus once the attendant waves you forward.
Safety Considerations Before and During a Wash
Learning how to use car wash mode on Tesla and Rivian vehicles is only half the picture. The other half is choosing the right kind of wash for your situation and paying attention to what is happening around the vehicle.
Safety Decision Path: Which Wash Should You Choose?
Practical guide only — always follow the posted rules of the specific wash facility you are visiting.
Safe Use vs Risky Use
Warning: Even with Car Wash Mode active, avoid pointing high-pressure water directly at charge ports, door seams, cameras, or ultrasonic sensors. These are sealed for normal weather exposure, not necessarily for close-range pressurized water.
Safety Note: Never attempt to inspect or work near the 12-volt battery, charge port wiring, or high-voltage components while the vehicle is at a wash or while it is wet. If you notice a warning light related to charging or electrical systems after a wash, park safely and check your owner’s manual before touching anything under the hood or near the charge port.
Common Problems With Car Wash Mode and How to Fix Them
Even experienced owners run into small hiccups with car wash mode on Tesla and Rivian vehicles from time to time. Most issues trace back to a handful of familiar causes.
A quick self-check before you drive off can catch most of these early.
Post-Wash Red-Flag Checklist
If any of these appear, park safely, restart the touchscreen if needed, and check the owner’s manual before driving further.
Common Mistakes Owners Make With Car Wash Mode
Most problems people run into with car wash mode on Tesla and Rivian vehicles come down to timing or a missed step, not the feature itself failing.
Pro Tips From Regular EV Owners
Owners who wash their Tesla or Rivian regularly tend to build small habits around car wash mode that go beyond the basic steps.
Rinse before you scrub
Rinsing loose dirt and grit off first, whether by hand or at the pre-soak stage of an automatic wash, reduces the chance of swirl marks from brushes dragging debris across the paint.
Favor touchless or soft-cloth options
Many owners lean toward touchless or soft-cloth automatic washes over stiff-brush tunnels, since factory paint on EVs is often reported as thinner than on some legacy vehicles and can show swirl marks more easily.
Dry the charge port area last
After a wash, gently wiping around the charge port and door seams can help avoid trapped moisture, especially before a cold night.
Keep a mental pre-wash checklist
Some users notice that mentally running through park, stop charging, activate the mode, and confirm neutral becomes second nature after just a few washes.
What Experienced Owners Check That Beginners Often Miss
Software update status
Experienced owners check for pending software updates before assuming Car Wash Mode is missing or broken, since a simple update sometimes restores or relocates the feature.
Tire pressure and parking brake
A quick glance confirms the parking brake or hold feature is not engaged before entering a conveyor, since that alone can stop the wash line.
Mirror and camera clearance
Folding mirrors in where possible and being mindful of exterior camera housings helps avoid brush contact in tight tunnel washes.
Wash chemical compatibility
Seasoned owners avoid highly acidic or highly alkaline wash chemicals on trim, lenses, and camera covers, since some cleaning formulas can cause discoloration or damage over time.

pH-Neutral Car Wash Soap
A pH-neutral formula may help with regular cleaning routines without stripping wax or ceramic coatings, and it can be a gentler option around trim and sensor housings during a Car Wash Mode session at home.
Microfiber Drying Towel Set
Large, soft microfiber towels can make day-to-day car care easier after a wash, helping soak up water around seams and the charge port area without dragging grit across the paint.
When to Contact a Professional
Contact a qualified mechanic or auto technician if: a warning light related to electrical systems, charging, or the charge port stays on after restarting the vehicle; you notice water intrusion inside the cabin or trunk area; the charge port will not close or lock properly; or the vehicle will not shift out of neutral or park after a wash. These situations go beyond what Car Wash Mode is designed to prevent and may need diagnostic tools or specialized repair. Do not attempt to open or inspect high-voltage components yourself.
FAQ
How do I turn on car wash mode on Tesla and Rivian vehicles?
On Tesla, open Controls and look under Service or a dedicated Car Wash option. On Rivian, open the vehicle icon and go to Access and Security. Select Car Wash Mode and confirm the on-screen prompt.
Is it safe to take a Tesla or Rivian through an automatic car wash?
Many owners use automatic washes regularly, but a touchless or soft-cloth wash is generally considered gentler on factory paint than a stiff-brush tunnel. Always activate Car Wash Mode first and check for any facility restrictions on EVs.
What happens if I forget to activate Car Wash Mode?
Sensors and wipers may react unexpectedly to water and brushes, which some owners report has led to wiper strain or charge port issues. Related repairs may not be covered under warranty, so it is worth checking your vehicle’s terms.
Does Car Wash Mode work for washing at home too?
Yes. Activating Car Wash Mode before a hose or hand wash at home can help keep sensors and wipers from reacting to spray water, the same way it helps at an automatic facility.
Why can’t I find Car Wash Mode on my touchscreen?
Menu locations have moved between software updates on both brands. Check for a pending software update, and look under Controls or Service on Tesla, or Access and Security on Rivian.
How do I know if my vehicle is actually in neutral for a conveyor wash?
Check the gear indicator on the touchscreen or instrument display. Both brands typically show a clear “N” or neutral status, and Car Wash Mode usually provides a dedicated on-screen button to confirm it.
Should I call a mechanic if something feels wrong after a wash?
Yes, if you see persistent warning lights, water inside the cabin, a charge port that won’t close, or the vehicle stuck in neutral. Contact a qualified mechanic or auto technician rather than attempting to inspect electrical components yourself.
Once you know how to use car wash mode on Tesla and Rivian, keeping your EV clean becomes a quick, low-stress routine rather than something to dread. Activate the mode, confirm neutral if needed, and pay attention to sensors and warning lights afterward.
For anything beyond routine cleaning, especially electrical warnings, water intrusion, or persistent faults, consult a qualified mechanic or auto technician, and always check your vehicle’s manual and local regulations before making any permanent modifications or installations.
