able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a 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. 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 improp-
erly. Refer to “Jump Starting” in “What To Do In
Emergencies” for further information.

After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
418 STARTING AND OPERATING

The engine block heater cord is located:
•3.6L Engine – coiled and strapped to the engine oil
dipstick tube.
•5.7L Engine – bundled and fastened to the injector
harness.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•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.
•Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
•Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
5
STARTING AND OPERATING 419

Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
The transmission shift lever has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) shift control (refer to “Electronic Range Select
(ERS)” in this section). Moving the shift lever to the left or
right (-/+) while in the DRIVE position will select the
highest available transmission gear, and will display that
gear in the instrument cluster as 4, 3, 2, 1.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.

422 STARTING AND OPERATING

WARNING! (Continued)
•Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the shift lever. Do not leave
the key fob in or near the vehicle, and do not leave
Keyless Enter-N-Go in the ACC or ON/RUN
mode. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
•Before moving the shift lever out of PARK, you
must turn the ignition switch from the LOCK/OFF
position to the ON/RUN position, and also press
the brake pedal. Otherwise, damage to the shift
lever could result.
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the shift lever into the PARK position:
•When shifting into PARK, move the shift lever all the
way forward and to the left until it stops and is fully
seated.
•Look at the shift lever position display and verify that
it indicates the PARK position.
5
STARTING AND OPERATING 425

•With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with engine running. The engine may be started
in this range. Set the parking brake and shift the trans-
mission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can result
in severe transmission damage. Refer to “Recre-
ational Towing” in “Starting And Operating” and
“Towing A Disabled Vehicle” in “What To Do In
Emergencies” for further information.
426 STARTING AND OPERATING

DRIVE
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first, second,
and third gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the Electronic Range
Select (ERS) feature (refer to “Electronic Range Select
(ERS)” in this section) to select a lower gear range. Under
these conditions, using a lower gear range will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will
remain in second gear regardless of which forward gear
is selected. PARK, REVERSE, and NEUTRAL will con-
tinue to operate. The Malfunction Indicator Light (MIL)
may be illuminated. Limp Home Mode allows the vehicle
to be driven to an authorized dealer for service without
damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
