ªLOCKº ± Engine is off and the steering wheel is
locked. The ignition key can be removed only at this
position.
You must push in the key to turn it from ªACCº to the
ªLOCKº position. The selector lever must be put in the
ªPº position before turning the key to the ªLOCKº
position.
Once you remove the key, the engine immobiliser
system is automatically set. See ªEngine immobiliser
systemº on page 12.
When
starting the engine, the key may seem stuck at the
ªLOCKº position. To free it, first be sure the key is
pushed all the way in, and then rock the steering wheel
slightly while turning the key gently.
If, in an emergency, you must turn the engine off while
the vehicle is moving, turn the key only to ªACCº.

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 ªPº. If you need to restart the
engine while the vehicle is moving, put the selector lever
in ªNº. 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
driving off.
Starting the engine
Before starting the engine, be sure to follow the
instructions in ªBefore 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 ªSTARTº. 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 ªIf your vehicle will not startº on page 343.
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
enabled because the cruise control is not
cancelled. For the operation to decrease the
vehicle speed, see page 300.
3Shift position indicator
The shift position is also displayed on the
instrument cluster.
P:Parking, engine starting and key removal

R: Reverse position
N: Neutral position

(a)Overdrive switch
31E082
You can select either third gear (with overdrive off) or
fourth gear (with overdrive on) by pushing this switch.
To turn the overdrive off, push the switch. The ªO/D
OFFº indicator light should come on. To turn the
overdrive on again, push the switch again. The ªO/D
OFFº indicator light should go off.
Always drive your vehicle with the overdrive on for better
fuel economy and quieter driving.
If the engine is turned off when the overdrive is off and
restarted, the overdrive will automatically be on.
When the cruise control is being used, even if you
downshift the transmission by pushing and releasing the
overdrive switch, engine braking will not be enabled
because the cruise control is not cancelled.
For ways to decrease the vehicle speed, see page 300.

1ªPº (Park) position 2ªNº (Neutral) position
1. Start the engine as instructed in ªHow to start the
engineº on page 283.
The transmission must be in ªPº or ªNº. The engine will
not start in ªRº, ª2º, ªLº or ªDº position even if \
the ignition
key is turned to ªSTARTº.

STARTING AND DRIVING

3. 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 on.
When the lever is in the ªDº 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 ª(c) Using engine brakingº.

(c) Using engine braking
31E009±2

STARTING AND DRIVING
291
To use the braking power of the engine, downshift the
transmission in the way described below:
1
Push the overdrive switch. (This is effective only
when you are driving in the ªDº position.) The ªO/D
OFFº indicator light in the instrument cluster will
come on and the transmission will downshift to third
gear.
When the cruise control is being used, even if you
downshift the transmission by pushing and
releasing the overdrive switch, engine braking will
not be enabled because the cruise control is not
cancelled. If you need to decrease the vehicle
speed, see page 300.
2 Shift into the ª2º position. The transmission will
downshift to second gear when the vehicle speed
is lower than 120 km/h (75 mph) and stronger
engine braking will be enabled.
3Shift into the ªLº position. The transmission will
downshift to first gear when the vehicle speed is
lower t han 55 km/h (34 mph) and maximum engine
braking will be enabled.
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
292
(d) Using the ª2º and ªLº positions
The ª2º and ªLº positions are used for strong engine
braking as described previously.
With the selector lever in ª2º or ªLº, you can start the
vehicle in motion as with the lever in ªDº.
With the selector lever in ª2º, the vehicle will start in first
gear and automatically shift to second gear.
With the selector lever in ªLº, the transmission is
engaged in first gear.
NOTICE
Be careful not to over±rev the engine. Watchthe tachometer to keep engine rpm from goinginto the red zone. The approximate maximumallowable speed for each position is givenabove for your reference.
ª2º 128 km/h (80 mph) . . .
ªLº 71 km/h (44 mph) . . .
Do not continue hill climbing or hard towing for
a long time in the ª2º or ªLº position. This maycause severe automatic transmission damagefrom overheating. To prevent such damage,
ªDº position should be used in hill climbing orhard towing.

STARTING AND DRIVING
295
(g) Good driving practice
If the transmission repeatedly shifts up and down
between the third and overdrive gears when climbing
a gentle slope, the overdrive should be turned off. 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.
(h) 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 backward as it becomes un±stuck,
causing injury or damage to nearby people or objects.
