Cleaning and protecting the vehicle exterior
●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.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused in a car wash etc.
●The coating lasts for 5 to 8 years after the coating has been performed.
●The restoration time differs depending on the depth of the scratch and outside temper-
ature. The restoration time may become shor ter when the coating is warmed by apply-
ing warm water.
●Deep scratches caused by keys or coins cannot be restored.
●Do not use wax that contain abrasives.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door (if equipped)
Start washing from the front of the vehicle. Extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm your
vehicle’s paint.
●Rear spoiler may not be washable in some automatic car washes. There may also be an
increased risk of damage to vehicle.
■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 prop-
erly.
Perform the following to protect the ve hicle and maintain it in prime condi-
tion:

■Note for a smart access system with push-button start
●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 insi de the vehicle and a door handle becomes wet during a car
wash, a buzzer will sound outside the vehicle. To turn off the alarm, lock all the doors.
●Set the electronic key to battery-saving mode to disable the smart access system with
push-button start. ( P. 1 4 1 )
■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
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coatin g (vehicles with water-repellent coating)
●The following precautions can extend the effectiveness of the water-repellent coating.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long period.
Clean the windows with a soft, da mp cloth as soon as possible.
• Do not use wax or glass cleaners that co ntain abrasives when cleaning the windows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance has become insufficient, the coating can be
