Occupants must use caution when op-
erating the seat heater because it

Adjust the mirror so that you can just
see the side of your vehicle in the mir-
ror.
Be careful when judging the size or dis-
tance of any object seen in the outside
rear view mirror on the passenger ’s side.
It is a convex mirror with a curved sur-
face. Any object seen in a convex mirror
will look smaller and farther away than
when seen in a flat mirror.
On some models, when you push the out-
side rear view mirror defogger switch, the
heater panels in the outside rear view
mirrors will quickly clear the mirror sur-
face. (See “Outside rear view mirror de-
fogger and windshield wiper deicer” on
page 98 in Section 14.)
CAUTION
Do not adjust the mirror while the
vehicle is moving. Doing so may
cause the driver to mishandle the
vehicle and an accident may occur
resulting in death or serious inju-
ries.
Since the mirror surfaces can get
hot, do not touch them when the
defogger switch is on.
To adjust a mirror, use the switches.
1. Master switch—To select the mirror to be adjusted
Push the switch to “L” (left) or “R”
(right).
2. Control switch—To move the mirror Push the switch in the desired direc-
tion.
Mirrors can be adjusted when the key is
in the “ACC” or “ON” position.

defoggers off.
The system will automatically shut off af-
ter the defogger has operated about 15

on for a long time could cause the battery
to discharge, especially during stopand
go driving. The defogger is not designed

window, be careful not to scratch or
damage the heater wires or connec-
tors.

Air conditioning control panel, car au-
dio, instrument panel, console panel,
and switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly wipe off dirt.
NOTICE
Do not use organic substances (sol-
vents, kerosene, alcohol, gasoline,
etc.) or alkaline or acidic solutions.
These chemicals can cause discol-
oring, staining or peeling of the
surface.
 If you use cleaners or polishing
agents, make sure their ingredients
do not include the substances men-
tioned above.
If you use a liquid car freshener, do
not apply the liquid onto the ve-
hicle’s interior surfaces. It may con-
tain the ingredients mentioned
above. Immediately clean any spill
using the method mentioned above.
Leather Interior
The leather upholstery may be cleaned
with neutral detergent for wool.
Remove dirt using a soft cloth dampened
with 5% solution of neutral detergent for
wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.
After cleaning or whenever any part of the
leather gets wet, dry with a soft clean
cloth. Allow the leather to dry in a venti-
lated shaded area.
NOTICE
If a stain should fail to come out
with a neutral detergent, apply a
cleaner that does not contain an
organic solvent.
 Never use organic substances such
as benzine, alcohol or gasoline, or
alkaline or acid solutions for clean-
ing the leather as these could
cause discoloring.
 Use of a nylon brush or synthetic
fiber cloth, etc. may scratch the
fine grained surface of the leather.
 Mildew may develop on soiled leath-
er upholstery. Be especially careful
to avoid oil spots. Try to keep your
upholstery always clean.
 Long exposure to direct sunlight
may cause the leather surface to
harden and shrink. Keep your ve-
hicle in a shaded area, especially in
the summer.
