3226-1. Maintenance and care
6-1.Maintenance and care
Working from top to bottom, liber-
ally 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 water-
proof 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 coat-
ing that is resistant to small surface
scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from
when the vehicle is delivered from the
plant.
●The restoration time differs depending on
the depth of the scratch and outside tem-
perature. The restoration time may
become shorter when the coating is
warmed by applying warm water.
●Deep scratches caused by keys, coins,
etc. 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 vehicl e 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
As water may enter the cabin, do not bring
the nozzle tip near the gaps around the
doors or perimeter of the windows, or spray
these areas continuously.
■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. In that case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the key in a position 6 ft. (2 m) or
more separate from the vehicle while the
vehicle is being wash ed. (Take care to
ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart access system
with push-button start. ( P.125)
●If the electronic key is inside the vehicle
and a door handle becomes wet during a
car wash, a buzzer may sound outside the
vehicle and “Key Detected in Vehicle”
may be shown on the multi-information
display. To turn off the alarm, lock all the
doors.
■Aluminum wheels
●Remove any dirt immediately by using a
neutral detergent.
●Wash detergent off with water immedi-
ately after use.

WARNING
The engine compartment contains many
mechanisms and fluids that may move
suddenly, become hot, or become elec-
trically energized. To avoid death or seri-
ous injury, observe the following
precautions.
■When working on the engine com-
partment
●Make sure that “IGNITION ON” on
the multi-information display and the
“READY” indicator are both off.
●Keep hands, clothi ng and tools away
from the moving fan and engine drive
belt.
●Be careful not to touch the engine,

may be hot. Oil and other fluids may
also be hot.
●Do not leave anything that may burn
easily, such as paper and rags, in the
engine compartment.
●Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are
flammable.
■When working near the electric cool-
ing fans or radiator grille
Be sure the power switch is OFF.
With power switch in ON, the electric
cooling fans may automatically start to
run if the air conditioning is on and/or the
coolant temperature is high. ( P.340)
