mode and start or stop the engine. (For details, see
“Selecting the mode” on page 344 and “Starting the engine” on

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.

When an obstacle is detected, the indicator bars will come
on or flash, accompanied by beeping. How many bars are
lit or flashing depends on the distance to the obstacle.
When the obstacle is not detected any longer, beeps will stop
sounding and the multi−information display and the screen will
return to the previous display.
The volume of the beeps and the display on the screen can be
changed. See “Setting the intuitive parking assist” on page

The steering guide symbol and the arrow indicating which
direction should be steered appear along with the bar
indicators and beeps.The above illustration indicates that the collision will be
avoided by turning the steering wheel clockwise.
When the possibility that the distance between the vehicle and
the obstacle is less than about 25 cm (0.8 ft.) is eliminated by
turning the steering wheel more, the steering guide symbol will
go out and the beeps will stop sounding.
The steering guide symbol and arrow are not instructions
you must observe. They are just a guide to avoid a
collision.

The indicator bars will come on in yellow depending on
the distance to the obstacle. The steering guide symbol
and arrow will also come on. In addition, the current
direction of the tires is also indicated in 3 stages.
Beeps:
As distance to the obstacle gets closer, the interval of the
intermittent sound gets shorter, and then finally to a continuous
sound when the distance between the vehicle and the obstacle
is less than about 25 cm (0.8 ft.).

STARTING AND DRIVING

vehicle, such as a horn from another vehicle, motorcycle
engine, air braking sound from heavy−duty vehicles.
When another vehicle equipped with ultrasonic sensors
gets close to your vehicle.
When heavy rain or water is splashed over the vehicle.
(Drive carefully as the braking distance may be affected.)

vehicle.
If towing eyelet is installed on your vehicle.
When you are driving towards a tall curb stone or curb stone
having right angle.
The detection range for an object such as a traffic sign may
be shortened.
An object just under the bumper cannot be detected.
Although an object lower than the location of sensors is
once detected, the detection might be stopped when your
vehicle gets closer to the object.
When an obstacle is very close to the sensors.
