interfere with seat movement.
Door opening linked seat sliding function
The rear seat automatically moves backward when the
rear door is opened if the seat is adjusted to a forward
position.
The ignition switch must be in the “ON” position.
This function is actuated when the selector lever is set in the
“P” position or if the vehicle is stopped with the brake pedal
depressed.
While the seat is being moved by this function, the operation
will not stop even if the door is closed midway.

PARKING BRAKE
31L628
1To set: Fully depress the parking brake pedal.
2To release: Pull the parking brake release lever.
Before leaving your vehicle, firmly apply 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
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3. Put the selector lever in “P”. If you need to restart the engine
while the vehicle is moving, put the selector lever in “N”. 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
“Before cranking”.
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:
With your foot off the accelerator pedal, crank the engine by
turning the ignition switch to “START”. Release it when the
engine starts.

STARTING AND DRIVING
305
The engine should be warmed up by driving, not in idle. For
warming
up, drive with smoothly turning engine until the engine
coolant temperature is within normal range.
If the engine stalls ...
Simply restart it, using the correct procedure given in normal
starting.
If the engine will not start
See “If your vehicle will not start” on page 400.
NOTICE
 Do not crank for more than 30 seconds at a time. This
may overheat the starter and wiring systems.
 Do not race a cold engine.
 If the engine becomes difficult to start or stalls
frequently, have the engine checked immediately.
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 “P” position when the
brake pedal is depressed with the ignition switch in “ON”
position. ( )

 1Brake pedal 2“D” (Drive) position
4. With your foot holding down the brake pedal, shift the
selector lever to “D”.
Always use the “D” 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 “D” position. (See “(c) Using engine braking” and “(f)
Good driving practice” for exceptions.)
CAUTION
Never put your foot on the accelerator pedal while
shifting.
5. 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.
If you need to accelerate rapidly while driving, depress the
accelerator pedal to the full throttle position. This provides
more acceleration by auto matically 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 “(c) Using engine braking”.
 AI (Artificial Intelligence) shifting control
AI shifting control selects the most suitable shift range
automatically according to the driver’s operation and
driving condition.
AI shifting control operates automatically with the
selector lever in the “D” position. When the lever is moved
to the “S” position, this function will be canceled.
Shifting control on the slope: On inclines, you can drive
smoothly with reduced shifting quantity. On declines, the
vehicle will shift down automatically to obtain optimum engine
braking and reduce the driver’s foot braking load.
Automatic shifting point change control: The most suitable
shift range is selected depending on the driver’s accelerator
pedal operation and vehicle condition.

(d) Backing up
31L324
 1Brake pedal 2“R” (Reverse) position
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the
selector lever to the “R” position.
NOTICE
Never shift into reverse while the vehicle is moving.
When the selector lever is shifted into the “R” position, the
outside rear view mirrors automatically down to help backing
up. For details, see “Power rear view mirror control” on page
231.
Vehicles with rear view monitor system: When the selector
lever is shifted into the “R” position with the ignition switch in\
the “ON” position, rear view monitor system will activate. For
instructions, see “Rear view monitor system” on page 323.
