*: The needle indicators may move slightly
after the ignition switch is placed in the
OFF position. This is not a malfunction.
CAUTION
. For cleaning, use a soft cloth, dam-
pened with water. Never use a rough
cloth, alcohol, benzine, thinner or any
kind of solvent or paper towel with a
chemical cleaning agent. They will
scratch or cause discoloration to the
lens.
. Do not spray any liquid such as water
on the meter lens. Spraying liquid
may cause the system to malfunction.

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (RPM).Do not rev
the engine into the red zone
.
The scale length and the red zone vary with
the engine model.
CAUTION
When engine speed approaches the red
zone, shift to a higher gear or reduce
engine speed. Operating the engine in
the red zone may cause serious engine
damage.
JVI0639X
ENGINE COOLANT TEMPERA-
TURE GAUGE
The gauge indicates the engine coolant
temperature.
The engine coolant temperature is within the
normal range when the gauge needle points
within the zone
shown in the illustration.
The engine coolant temperature varies with
the outside air temperature and driving
conditions.
CAUTION
If the gauge indicates the engine coolant
temperature is near the hot (H) end of
the normal range, reduce vehicle speed
to decrease the temperature. If the
gauge is over the normal range, stop
the vehicle as soon as safely possible and
let the engine idle. If the engine is
overheated, continued operation of the
vehicle may seriously damage the engine.
See “If your vehicle overheats” (P.6-16)
for immediate action required.

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions in-
terfere with the Intelligent Key operation,
start the engine according to the following
procedure:
1. Move the shift lever to the P (Park)position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime
will sound.)
4. Push the ignition switch while depressing the brake pedal within 10 seconds after
the chime sounds. The engine will start.
After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears in the vehicle information
display even if the Intelligent Key is
inside the vehicle. This is not a malfunc-
tion. To turn off the Intelligent Key
battery discharge indicator, touch the
ignition switch with the Intelligent Key
again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery as
soon as possible. (See “Intelligent Key
battery replacement” (P.8-26).) .
Make sure the area around the vehicle is
clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window washer
fluid as frequently as possible, or at least
whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
. Lock all doors.
. Position seat and adjust head restraints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passengers
to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to the
ON position. (See “Warning lights, in-
dicator lights and audible reminders”
(P.2-10).)
