Maintenance and care
■Brake pads and calipers
Rust may form if the vehicle is parked with wet brake pads or disc rotors, caus-ing them to stick. Before parking the
vehicle after it is washed, drive slowly and apply the brakes several times to dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Plated portions (if equipped)
If dirt cannot be removed, clean the parts as follows:
●Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to remove any remaining moisture.
●To remove oily deposits, use alcohol wet wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may cause the electrical components, etc.
to catch fire.
■When cleaning the windshield (vehicles with rain-sensing wind-shield wipers)
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.
Off
AUTO
●When the upper part of the wind- shield where the raindrop sensor is located is touched by hand
●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.

■To prevent damage to the wind-
shield wiper arms
When lifting the wiper arms away from the windshield, pull the driver
side wiper arm upward first, and repeat for the passenger side. When returning the wipers to their original
position, do so from the passenger side first.
■When using an automatic car wash (vehicles with rain-sensing windshield wipers)
Set the wiper switch to the off posi- tion. If the wiper switch is in “AUTO”, the wipers may operate and the wiper
blades may be damaged.
■When using a high pressure car
wash
●Vehicles with rear view monitor sys- tem: When washing the vehicle, do
not spray the camera or its sur- rounding area directly with a high pressure washer. Shock applied
from high pressure water may cause the device to not operate normally.
●Do not spray water directly on the radar which is equipped behind the
emblem. Otherwise it may cause the device to be damaged.
