ªACCº Ð Accessories such as the radio operate, but the
engine is off.
If you leave the key in the ªACCº or ªLOCKº position and open
the driver's door, a buzzer will remind you to remove the key.
ªLOCKº Ð Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the key from ªACCº to the ªLOCKº position, you must
put the transmission selector lever in the ªPº position.
Once you remove the key, the engine immobilizer system is
automatically set. See ªEngine immobilizer systemº on page
14.
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.
Approximately
five hours after the engine is turned off, you may
hear sound coming from underneath the luggage compartment
for several minutes. This is normal operation and does not
indicate a malfunction. (See ªLeak detection pumpº on page
vi.)
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to ªACCº.

STARTING AND DRIVING

AUTOMATIC TRANSMISSION
Your automatic transmission has a shift lock system to
minimize the possibility of incorrect operation. This
means you can only shift out of ªPº position when the
brake pedal is depressed with the ignition switch in ªONº
position. ()
31PY039

The shift position is displayed beside the selector lever
and on the instrument cluster.
P: Parking, engine starting and key removal position
R: Reverse position
N: Neutral position
D: Normal driving position (Shifting into overdrive possible)
4: Position for engine braking (Shifting into overdrive not
possible)
When the cruise control is being used, even if you
downshift from ªDº to ª4º, engine braking will not be
enabled because the cru ise control is not cancelled. For
the operation to decrease the vehicle speed, see page
421.

L: Position for maximum engine braking

STARTING AND DRIVING
404Correct use of the automatic transmission is explained in
the following parts.
(a) Normal driving
(b) Using engine braking
(c) Using the ª3º, ª2º and ªLº positions
(d) Backing up
(e) Parking
(f) Good driving practice
(g) If you cannot shift the selector lever
(h) Driving in second start mode
(a) Normal driving

1ªPº (Park) position2ªNº (Neutral) position
1. Start the engine as instructed in ªHow to start the
engineº on page 401.
The transmission must be in ªPº or ªNº. The engine will not st\
art
in any drive position even if the ignition key is turned to
ªSTARTº.

STARTING AND DRIVING
405

1Brake pedal2ªDº (Drive) position
2. With your foot holding down the brake pedal, shift the
selector lever to ªDº.
Always use the ªDº position to improve fuel economy and quiet
driving. Only in this position, shifting into the overdrive gear is
possible. However, while the engine coolant temperature is
low, the transmission will not shift into the overdrive gear even
in the ªDº position. (See ª(b) Using engine brakingº and\
ª(f)
Good driving practiceº for exceptions.)
CAUTION
Never put your foot on the accelerator pedal while
shifting.
3. Release the parking brake and brake pedal. Depress
the accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in first gear and
automatically shift up to the most suitable gear. On inclines,
declines or winding roads, etc., the vehicle shifts up and down
automatically according to the running conditions to obtain the
suitable driving power and engine braking.
When the lever is in the ª4º 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, depress the
accelerator pedal to the full throttle position. This provides
more acceleration by automatically downshifting the
transmission to the next lower gear or beyond, depending on
the vehicle speed.
If engine braking is needed, such as in descending a long hill,
see ª(b) Using engine brakingº.

STARTING AND DRIVING
406
(b) Using engine braking
To use the braking power of the engine, downshift the
transmission in the way described below:
1Shift into the ª4º position. The transmission will downshift
to fourth gear and engine braking will be enabled.
When the cruise control is being used, even if you
downshift from ªDº to ª4º, engine braking will not be
enabled because the cruise control is not cancelled. If
you need to decrease the vehicle speed, see page 421.
2Shift into the ª3º position. The transmission will downshift
to third gear when the vehicle speed is or becomes lower
than the speed listed below and stronger engine braking
will be enabled.
Transfer ªHº 135 km/h (84 mph) ªLº 52 km/h (32 mph)
3Shift into the ª2º position. The transmission will downshift
to second gear when the vehicle speed is or becomes
lower than the speed listed below and more powerful
engine braking than that of ª3º position will be enabled.
Transfer ªHº 89 km/h (55 mph) ªLº 34 km/h (21 mph)
4Shift into the ªLº position. The transmission will downshift
to first gear when the vehicle speed is or becomes lower
than the speed listed below and maximum engine braking
will be enabled.
Transfer ªHº 39 km/h (24 mph) ªLº 15 km/h (9 mph)
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to skid or spin.

STARTING AND DRIVING
407
(c) Using the ª3º, ª2º and ªLº positions
The ª3º, ª2º and ªLº positions are used for strong engine\
braking
as described previously.
With the selector lever in ª3º, ª2º or ªLº, you can start the vehicle
in motion as with the lever in ªDº.
With the selector lever in ª3º or ª2º, the vehicle will star\
t 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. Watch the tachometer to keep engine rpm from going into thered zone. The approximate maximum allowablespeed for each position is given below for yourreference:
Transmission Transfer ªLº ªHº
ª3º 60 km/h (37 mph) 154 km/h (96 mph) ª2º 41 km/h (25 mph) 105 km/h (65 mph)ªLº 24 km/h (15 mph) 61 km/h (38 mph)
Do not continue hill climbing or hard towing for a long time in the ª3º, ª2º or ªLº position. This may causesevere automatic transmission damage from
overheating. To prevent such damage, ª4º positionshould be used in hill climbing or hard towing.

(e) Parking

1Brake pedal
2Parking brake lever
3ªPº (Park) position
1. Bring the vehicle to a complete stop.
2. Apply the parking brake fully.
3. With the brake pedal held down with your foot, shift the
selector lever to the ªPº position.
CAUTION
While the vehicle is moving, never attempt to move the
selector lever into ªPº under any circumstances.
Serious mechanical damage and loss of vehicle control
may result.
(f) Good driving practice
 If the transmission repeatedly shifts up and down between
the fourth and overdrive gears when climbing a gentle slope,
shift the selector lever to the ª4º position. Be sure to shift the
selector lever to the ªDº position after climbing the slope.
