STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•When leaving the vehicle, always make sure the
keyless ignition node is in the OFFmode, remove
the Key Fob from the vehicle and lock the vehicle.
•
Never leave children alone in a vehicle, or with access
to an unlocked vehicle. Leaving children in a vehicle
unattended is dangerous for a number of reasons. A
child or others could be seriously or fatally injured.
Children should be warned not to touch the parking
brake, brake pedal or the shift lever.
(Continued)
WARNING! (Continued)
•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™ ACC or RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
Automatic Transmission
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.

STARTING AND OPERATING 391

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.
Using Fob With Integrated Key (Tip Start)
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
Do not press the accelerator. Use the Fob with Integrated
Key to briefly turn the ignition switch to the START
position and release it as soon as the starter engages. The
starter motor will continue to run, and it will disengage
automatically when the engine is running. If the engine
fails to start, the starter will disengage automatically in
10 seconds. If this occurs, turn the ignition switch to the
LOCK position, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
392 STARTING AND OPERATING

Keyless Enter-N-Go™
This feature allows the driver to oper-
ate the ignition switch with the push
of a button, as long as the Remote
Start/Keyless Enter-N-Go™ Key Fob
is in the passenger compartment.
Normal Starting
Using The ENGINE START/STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pressing 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, press the button again.
NOTE: Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.

5
STARTING AND OPERATING 393

3. If the shift lever/shift selector is not in PARK, theENGINE START/STOP button must be held for two
seconds or three short presses 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 shift lever/shift selector
is in PARK and the button is pressed twice to the OFF
position. If the shift lever/shift selector is not in PARK
and the ENGINE START/STOP button is pressed
once, the EVIC (if equipped) 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

the vehicle and use the accessories follow these steps:
• Starting with the ignition in the OFF position,
• Press the ENGINE START/STOP button once to place
the ignition to the ACC position (EVIC will display

394 STARTING AND OPERATING

Extreme Cold Weather (Below –20°F Or 29°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.
• 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.
(Continued)
WARNING! (Continued)
•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.
