STARTING AND DRIVING

NOTICE
Do not leave the key in the ONº position if the engineis not running. The battery will discharge and theelectronic ignition system could be damaged.
ACCº Ð Accessories such as the radio operate, but the
engine is off.
If you leave the key in the ACCº or LOCKº position and open
the driver's door, a buzzer will remind you to remove the key.
LOCKº 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 ACCº to the LOCKº position, you must
put the transmission selector lever in the Pº position.
Once you remove the key, the engine immobilizer system is
automatically set. See Engine immobilizer systemº on page
14.
When starting the engine, the key may seem stuck at the
LOCKº 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 ACCº.

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 Pº position when the
brake pedal is depressed with the ignition switch in ONº
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 Dº to 4º, engine braking will not be
enabled because the cru ise control is not cancelled. For
the operation to decrease the vehicle speed, see page
411.
3, 2: Position for more powerful engine braking
L: Position for maximum engine braking

STARTING AND DRIVING
394Correct use of the automatic transmission is explained in
the following parts.
(a) Normal driving
(b) Using engine braking
(c) Using the 3º, 2º and Lº 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

1Pº (Park) position2Nº (Neutral) position
1. Start the engine as instructed in How to start the
engineº on page 392.
The transmission must be in Pº or Nº. The engine will not start
in any drive position even if the ignition key is turned to
STARTº.

STARTING AND DRIVING

1Brake pedal2Dº (Drive) position
2. With your foot holding down the brake pedal, shift the
selector lever to Dº.
Always use the Dº 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 Dº position. (See (b) Using engine brakingº and (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 4º 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 (b) Using engine brakingº.
