How to start the engine
Before starting the engine, be sure to follow the instructions.
CRANKING HOLD FUNCTION
Once you push the engine switch while the brake pedal is
depressed, the cranking hold function continues to crank the
engine in “IG−ON” mode until it starts.
The function stops cranking the engine after about 25 seconds
at maximum if the engine has not started yet. When you crank
the engine again, wait a few seconds and restart it.
BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, seat cushion angle,
seat cushion height, head restraint height and steering wheel
angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
Remember to check that the service reminder indicators
function when the engine switch is selected in “IG−ON” mode,
and check the fuel gauge to see that you have sufficient fuel.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.
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:

Stopping the engine
G31036
If you press the engine switch while the selector lever is
in “P” and the engine is running, regardless of brake pedal
position, the engine will be turned off.
With the transmission not in “P”, the engine switch is selected
in “ACC” mode.
If, in an emergency, you must turn the engine off while the
vehicle is moving, press the engine switch for more than 3
seconds. At this time, “ACC” mode is selected.
Several hours after the engine is turned off, you may hear a
sound coming from underneath the luggage compartment for
several minutes. This is normal operation and does not
indicate a malfunction. (See page v.)
CAUTION
To avoid serious personal injury or an accident, observe
the following precautions.
Turn off the engine, only when the vehicle is
completely stopped.
When you leave the vehicle, the selector lever must
be in “P” and the parking brake must be applied, or
the vehicle may suddenly move.

To set: Hold the regular brake pedal down with your right
foot. Push down the parking brake pedal with your left
foot.
To release: Hold the regular brake pedal down with your
right foot and push the parking brake pedal with your left
foot. When you lift your left foot, the parking brake pedal
will follow it to the released position.
Before leaving your vehicle, firmly apply the parking brake.
To remind you that the parking brake is set, the parking brake
reminder light in the instrument cluster remains on until you
release the parking brake.The buzzer will remind you to release the parking brake when
the vehicle speed rises above 5 km/h (3mph) with the parking
brake is applied. At this time the master warning light blinks
and the message “PARK BRAKE” appears on the
multi−information display.
CAUTION
Before driving, make sure the parking brake is fully
released and that the parking brake reminder light is off.

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 engine switch in
“IG−ON” mode. ()

The shift position or shift range position is displayed
on the instrument cluster.

“P” (Park) position 2
“N” (Neutral) position
1. Start the engine as instructed in “Operating the engine
switch” on page 342.
The transmission must be in “P” or “N” position. The engine will
not start in any drive position even if engine switch is pushed
while the brake pedal is depressed.

STARTING AND DRIVING
3565. 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 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 “(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 automatic
shifting point control is controlled in the following way to
respond to the driver’s operation.
When the accelerator is depressed quickly, the vehicle
downshifts rapidly in order to improve acceleration.
When the accelerator is quickly released, the gear position
is maintained in order to improve engine braking and
reacceleration capabilities.
During hard deceleration the vehicle downshifts rapidly in
order to improve engine braking and reacceleration
capabilities.

“P” (Park) position
1. Bring the vehicle to a complete stop.
2. Depress the parking brake pedal fully to securely apply the
parking brake.
3. With the brake pedal held down with your foot, shift the
selector lever to the “P” position.
CAUTION
Never attempt to move the selector lever into “P” under
any circumstances while the vehicle is moving. Serious
mechanical damage and loss of vehicle control may
result.
(f) Good driving practice
If the transmission repeatedly shifts up and down between
fourth and overdrive gears when climbing a gentle slope, shift
the selector lever to the “4” position. Be sure to shift the
selector lever to the “D” position after climbing the slope.
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 the parking brake to hold
the vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.
