brake. Always make sure the keyless ignition node
is in the “OFF” mode, remove the Key Fob from the
vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with

(Continued)
WARNING! (Continued)
touch the parking brake, brake pedal or the gear
selector.
• Do not leave the key fob in or near the vehicle, or
in a location accessible to children, and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ACC or ON/RUN mode.
A child could operate power windows, other con-
trols, or move the vehicle.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.

STARTING AND OPERATING 463

CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
• Shift into PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
• Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
Keyless Enter-N-Go — Ignition
This feature allows the driver to oper-
ate the ignition switch with the push
of a button, as long as the Remote

START/STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
464 STARTING AND OPERATING

3. The system takes over and attempts to start thevehicle. 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
START/STOP Button
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 Driver Information
Display (DID) will display a “Vehicle Not In Park”
message and the engine will remain running. Never
leave a vehicle out of the PARK position, or it could
roll.
NOTE: If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after 30
minutes of inactivity and the ignition will switch to the
OFF position.

ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has four positions, OFF, ACC, RUN
and START. To change the ignition positions without
starting the vehicle and use the accessories follow these
steps:
•Starting with the ignition in the OFF position,
• Push the ENGINE START/STOP button once to place
the ignition to the ACC position (DID will display
“ACC”),
• Push the ENGINE START/STOP button a second time
to place the ignition to the RUN position (DID will
display “ON/RUN”), •
Push the ENGINE START/STOP button a third time to
return the ignition to the OFF position (DID will
display “OFF”).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
WARNING!
• Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.

466 STARTING AND OPERATING

WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
• If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly. Refer
to “Jump-Starting” in “What To Do In Emergen-
cies” for further information.
Clearing A Flooded Engine (Using ENGINE
START/STOP Button)
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather proce-
dures, it may be flooded. To clear any excess fuel:
1. Press and hold the brake pedal.
2. Press the accelerator pedal all the way to the floor and hold it.
3. Push and release the ENGINE START/STOP button once.
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.

vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and your foot is
