STARTING AND DRIVING
401
To set: Pull up the lever. For better holding power, first
depress the brake pedal and hold it while setting the
parking brake.
To release: Pull up the lever slightly (
1), press the lock
release button (2), and lower the lever (3).
Before leaving your vehicle, firmly apply the parking brake. For
better holding power, first depress the brake pedal and hold it
while setting the parking brake.
CAUTION
Before driving, make sure the parking brake is fully
released and that the parking brake reminder light is off.
HOW TO START THE ENGINE
Cranking hold function
Once you turn the ignition key to ªSTARTº position and release
it, the cranking hold function continues to crank the engine in
ªONº position until it starts.
The function stops cranking the engine after about 25 seconds
maximum if the engine has not started yet. When you crank
the engine again, wait a few seconds and restart it.
If you hold the key in ªSTARTº position, the function will keep
cranking for about 30 seconds maximum.
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 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

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.

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.

STARTING AND DRIVING
410
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
Always use the brake pedal or parking brake to hold the
vehicle on an upgrade. Do not attempt to hold the vehicle using the accelerator pedal, as this can causethe transmission to overheat.
