Toyota Sienna 2010-2026 Owners Manual / Maintenance and care / Maintenance and care / Cleaning and protecting the vehicle exterior

Perform the following to protect the vehicle and maintain it in prime condition:

Working from top to bottom, liberally apply water to the vehicle body, wheel wells and underside of the vehicle to remove any dirt and dust.
Wash the vehicle body using a sponge or soft cloth, such as a chamois.
For hard-to-remove marks, use car wash soap and rinse thoroughly with water.
Wipe away any water.
Wax the vehicle when the waterproof coating deteriorates.

If water does not bead on a clean surface, apply wax when the vehicle body is cool.

Automatic car washes

Before washing the vehicle:

Fold the mirrors.
Turn off the power back door system. (if equipped)
Turn off the power sliding door system. (if equipped)

Start washing from the front of the vehicle. Make sure to extend the mirrors before driving.

Brushes used in automatic car washes may scratch the vehicle surface and harm your vehicle’s paint.

High pressure car washes

Do not allow the nozzles of the car wash to come within close proximity of the windows.
Before using the car wash, check that the fuel filler door on your vehicle is closed properly.

When using a car wash (vehicles with a smart key system)

If the door handle becomes wet while the electronic key is within the effective range, the door may lock and unlock repeatedly. Place the key in a position 6 ft. (2 m) or more separate from the vehicle while the vehicle is being washed. (Take care to ensure that the key is not stolen.)
If the electronic key is inside the vehicle and a door handle becomes wet during a car wash, a message may be shown on the multi-information display and a buzzer will sound outside the vehicle. To turn off the alarm, lock all the doors.

Aluminum wheels

Remove any dirt immediately by using a neutral detergent. Do not use hard brushes or abrasive cleaners. Do not use strong or harsh chemical cleaners.
Use the same mild detergent and wax as used on the paint.
Do not use detergent on the wheels when they are hot, for example after driving for long distance in the hot weather.
Wash detergent from the wheels immediately after use.

Bumpers and side moldings

Do not scrub with abrasive cleaners

WARNING

Toyota Sienna. When cleaning the windshield

Set the wiper switch to off.

If the wiper switch is in “AUTO”, the wipers may operate unexpectedly in the following situations, and may result in hands being caught or other serious injuries and cause damage to the wiper blades.

When a wet rag or similar is held close to the raindrop sensor
If something bumps against the windshield
If you directly touch the raindrop sensor body or if something bumps into the raindrop sensor

Precautions regarding the exhaust pipe

Exhaust gasses cause the exhaust pipe to become quite hot.

When washing the vehicle, be careful not to touch the pipe until it has cooled sufficiently, as touching a hot exhaust pipe can cause burns.

Precaution regarding the Blind Spot Monitor

If the paint of the rear bumper is chipped or scratched, the system may malfunction.

If this occurs, consult your Toyota dealer.
