HOW TO START THE ENGINE
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3. Put the selector lever in ºPº. If you need to restart the
engine while the vehicle is moving, put the selector lever
in ºNº. A starter safety device will prevent the starter
from operating if the selector lever is in any drive
position.
4. Depress the brake pedal and hold it to the floor until
you are ready to drive off.
Starting the engine
Before starting the engine, be sure to follow the
instructions in ºBefore crankingº.
Normal starting procedure
The multiport fuel injection system/sequential multiport
fuel injection system in your engine automatically
controls the proper air±fuel mixture for starting. You can
start a cold or hot engine as follows:
1. With your foot off the accelerator pedal, crank the
engine by turning the key to ºSTARTº. Release it when
the engine starts.
2. After the engine runs for about 10 seconds, you are
ready to drive. If the weather is below freezing, let the engine warm up
for a few minutes before driving. Do not leave the vehicle
while the engine is warming up.
If the engine stalls ...
Simply restart it , using the correct procedure given in
normal starting.
If the engine will not start
See ºIf your vehicle will not startº on page 314.
NOTICE
Do not crank for more than 30 seconds at a
time. This may overheat the starter and wiringsystems.
Do not race a cold engine.
If the engine becomes difficult to start or stallsfrequently, have the engine checkedimmediately.

2Overdrive switch
For selecting either a three±speed or four±speed
transmission.
When the cruise control is being used, even if you
downshift the transmission by turning off the
overdrive switch, engine braking will not be applied
because the cruise control is not cancelled. For the
operation to decrease the vehicle speed, see page
277.

The shift position is also displayed on the
instrument cluster.

1ºPº (Park) position 2ºNº (Neutral) position
1. Start the engine as instructed in ºHow to start the
engineº on page 260.
The transmission must be in ºPº or ºNº. The engine will
not start in ºRº, º2º, ºLº or ºDº position even if \
the ignition
key is turned to ºSTARTº.

2. Set the overdrive switch to the ON position.
Always set the overdrive switch to the ON position to
improve fuel economy and quiet driving. (See º(b) Using
engine brakingº and º(f) Good driving practiceº for
exceptions.)

STARTING AND DRIVING
2664. Release the parking brake and brake pedal.
Depress the accelerator pedal slowly for smooth
starting.
The vehicle will start in the first gear and automatically
shift to the most suitable gear for the running conditions,
such as the vehicle speed, hill climbing, hard towing, etc.
However, while the engine coolant temperature is low
and the vehicle is traveling at low speed, the
transmission will not shift into the overdrive gear even
with the overdrive switch on.
In ºDº position, the automatic transmission system will
select the most suitable gear for the running conditions
such as hill climbing, hard towing, etc.
If you need to accelerate rapidly while driving, push the
accelerator pedal all the way to the floor. The
transmission will automatically downshift to the third,
second or first gear, according to the vehicle speed.
If engine braking is needed, such as in descending a
long hill, see º(b) Using engine brakingº.

STARTING AND DRIVING

(b) Using engine braking
31E009±2
To use the braking power of the engine, downshift the
transmission in the way described below:
1Turn off the overdrive switch. (This is effective only
when you are driving in the ºDº position.) The ºO/D
OFFº indicator light in the instrument cluster will
come on and the transmission will downshift to the
third gear and engine braking will be obtained.
When the cruise control is being used, even if you
downshift the transmission by turning off the
overdrive switch, engine braking will not be applied
because the cruise control is not cancelled. If you
need to decrease the vehicle speed, see page 277.
2 Shift into the º2º position. The transmission will
downshift to the second gear when the vehicle
speed is lower than 122 km/h (76 mph) and more
powerful engine braking will be obtained.
3Shift into the ºLº position. The transmission will
downshift to the first gear when the vehicle speed
is lower than 55 km/h (34 mph) and maximum
engine braking will be applied.

STARTING AND DRIVING
268
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to spin or skid.

STARTING AND DRIVING
269
(c) Using the º2º and ºLº positions
The º2º and ºLº positions are used for strong engine
braking as described previously.
With the selector lever in º2º or ºLº, you can start the
vehicle in motion as with the lever in ºDº.
With the selector lever in º2º, the vehicle will start in the
first gear and automatically shift to the second gear.
With the selector lever in ºLº, the transmission is
engaged in the first gear.
NOTICE
Be careful not to overrev the engine. Watch thetachometer to keep engine rpm from going intothe red zone. The approximate maximumallowable speed for each position is givenabove for your reference.
º2º 128 km/h (80 mph) . . .
ºLº 70 km/h (43 mph) . . .
Do not continue hill climbing or hard towing for
a long time in the º2º or ºLº position. This maycause severe automatic transmission damagefrom overheating. To prevent such damage,
ºDº position should be used in hill climbing orhard towing.

STARTING AND DRIVING
272
(f) Good driving practice
If the transmission repeatedly upshifts and
downshifts between the third and overdrive gears
when climbing a gentle slope, turn off the overdrive
switch. Be sure to turn the switch on immediately
after climbing the slope.
 When towing a trailer, in order to maintain efficient
engine braking and electrical charging performance,
do not use overdrive.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Do not hold the vehicle on an upgrade with the accelerator pedal. This can cause thetransmission to overheat. Always use the brakepedal or parking brake.
(g) Rocking your vehicle if stuck
CAUTION
If your vehicle becomes stuck in snow, mud, sand, etc.,
then you may attempt to rock the vehicle free by moving
it forward and backward. Do not attempt this procedure
if people or objects are anywhere near the vehicle.
During the rocking operation the vehicle may suddenly
move forward or back as it becomes un±stuck, causing
injury or damage to nearby people or objects.

STARTING AND DRIVING
273
NOTICE
If you rock your vehicle, observe the followingprecautions to prevent damage to thetransmission and other parts.
Do not depress the accelerator pedal whileshifting the selector lever or before thetransmission is completely shifted to forwardor reverse gear.
Do not race the engine and avoid spinning thewheels.
If your vehicle remains stuck after rocking thevehicle several times, consider other wayssuch as towing.
(h) If you cannot shift the selector lever out of ºPº position
If you cannot shift the selector lever from ºPº position
even though the brake pedal is depressed, use the shift
lock override button. For instructions, see ºIf you cannot
shift automatic transmission selector leverº on page
346.
