Using The ENGINE START/STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pushing theENGINE START/STOP button once.
3. The system takes over and attempts to start the vehicle. If the vehicle fails to start, the starter will
disengage automatically after 10 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
To Turn Off The Engine Using ENGINE

1. Place the gear selector in PARK, then push and release the ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3. If the gear selector is not in PARK, the ENGINE START/STOP button must be held for two seconds or
three short pushes in a row with the vehicle speed
above 5 mph (8 km/h) before the engine will shut off.
The ignition switch position will remain in the ACC
position until the gear selector is in PARK and the
button is pushed twice to the OFF position. If the gear
selector is not in PARK and the ENGINE START/
STOP button is pushed once, the EVIC/DID will

ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or

the vehicle and use the accessories follow these steps:
1. Starting with the ignition in the OFF position:
2. Push the ENGINE START/STOP button once to change the ignition to the ACC position.
3. Push the ENGINE START/STOP button a second time to change the ignition to the RUN position. 4. Push the ENGINE START/STOP button a third time to
return the ignition to the OFF position.
Extreme Cold Weather (Below –22°F Or 30°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while the engine is cranking. This should clear any
excess fuel in case the engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release
the accelerator pedal and the brake pedal, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
