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 following precautions.
Turn off the engine, only when the vehicle is
completely stopped.

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
