2846-1. Maintenance and care
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehi-
cle.
Doing so may cause electrical compo-
nents, etc. to malfunction or catch fire.
●Do not get any of the SRS components
or wiring in the vehicle interior wet.
( P.28)
An electrical malfunction may cause
the airbags to deploy or not function
properly, resulting in death or serious
injury.
■Cleaning the interior (especially
instrument panel)
Do not use polish wax or polish cleaner.
The instrument panel may reflect off the
windshield, obstructing the driver’s view
and leading to an accident, resulting in
death or serious injury.
NOTICE
■Cleaning detergents
●Do not use the following liquids, as
they may discolor the vehicle interior
or cause streaks or damage to painted
surfaces:
• Audio system screen: Organic sub- stances such as benzine or gasoline,
alkaline solutions, and alcohol
• Seats: Alkaline solutions, organic sub- stances such as thinner or benzine,
and alcohol
• Other parts: Organic substances such as benzine or gasoline, alkaline or
acidic solutions, dye, and bleach
●Do not use polish wax or polish
cleaner. The instrument panel’s or
other interior part’s painted surface
may be damaged.
■Preventing damage to leather sur-
faces
Observe the following precautions to
avoid damage to and deterioration of
leather surfaces:
●Remove any dust or dirt from leather
surfaces immediately.
●Do not expose the vehicle to direct
sunlight for extended periods of time.
Park the vehicle in the shade, espe-
cially during summer.
●Do not place items made of vinyl, plas-
tic, or containing wax on the uphol-
stery, as they may stick to the leather
surface if the vehicle interior heats up
significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system
may be damaged if water comes into
contact with electrical components such
as the audio system above or under the
floor of the vehicle. Water may also
cause the body to rust.
■When cleaning the inside of the wind-
shield
Do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
(
P.164)
■Cleaning the inside of the rear win-
dow
●Do not use glass cleaner to clean the
rear window, as this may cause dam-
age to the rear window defogger
heater wires or antenna. Use a cloth
dampened with lukewarm water to
gently wipe the window clean. Wipe
the window in strokes running parallel
to the heater wires or antenna.
●Be careful not to scratch or damage
the heater wires or antenna.

Doors/trunk• Do the doors/trunk operate smoothly?
Engine hood
•Does the engine hood lock system
work properly?
Fluid leaks

leakage after the
vehicle has been
parked.
ItemsCheck points
Tires
• Is the tire inflation pressure correct?
• The tires should not be damaged or
excessively worn.
• Have the tires been rotated according to
the maintenance
schedule?
•The wheel bolts should not be loose.
Windshield wip-
ers
• The wiper blades should not show any

3888-1. Specifications
cornering (turning) traction.
■Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. Grade C corresponds to
a level of perfor-
mance which all passenger car tires must
meet under the Fede ral Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is properly inflated and not
overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
