Operating tips
• The power seat motor has an auto-resetoverload protection circuit. If the motor
stops during operation, wait 30 seconds
then reactivate the switch.
• Do not operate the power seat switch for a long period of time when the engine is off.
This will discharge the battery.
For additional information, see “Memory
seat” (P. 3-36).
Forward and backward
Moving the switch as shown will slide the
seat forward or backward to the desired
position.
Reclining
Move the recline switch as shown until the
desired angle is obtained. The reclining feature allows adjustment of
the seatback for occupants of different sizes
for added comfort and to help obtain proper
seat belt fit. For additional information, see
“Precautions on seat belt usage” (P. 1-11).
Also, the seatback can be reclined to allow
occupants to rest when the vehicle is stopped
and the shift lever is in P (Park).

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm). Do not rev the
engine into the red zone
O1.
CAUTION
When engine speed approaches the red
zone, reduce engine speed. Operating the
engine in the red zone may cause serious
engine damage.
ENGINE COOLANT
TEMPERATURE GAUGE
The gauge indicates the engine coolant tem-
perature. The engine coolant temperature is
within the normal range
O1when 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 coolant temperature
near the hot (H) end of the normal range,
reduce vehicle speed to decrease tempera-
ture. If the gauge is over the normal range,
stop the vehicle as soon as safely possible.
If the engine is overheated, continued op-
eration of the vehicle may seriously dam-
age the engine. For additional information,
see “If your vehicle overheats” (P. 6-7) for
immediate action required.
