STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 15-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!
Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
shift lever. Do not leave the key fob in the vehicle. A
child could operate power windows, other controls,
or move the vehicle.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Turn the key fob to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key fob to the OFF position, wait five
seconds, then repeat the “Normal Starting” procedure.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting into any
driving range.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
pressed to shift out of PARK.5
STARTING AND OPERATING 279
Page 284 of 508
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.
(Continued)
CAUTION! (Continued)
•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.
282 STARTING AND OPERATING

WARNING!
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
and remove the key fob. Once the key fob is
removed, the shift lever is locked in the PARK
position, securing the vehicle against unwanted
movement. Furthermore, you should never leave
unattended children inside a vehicle.
(Continued)
WARNING! (Continued)
•Leaving children in a vehicle unattended is dan-
gerous 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. Do not leave the key
fob in the vehicle. A child could operate power
windows, other controls, or move the vehicle.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your foot is firmly pressing the brake pedal.5

Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
before the ignition switch can be turned to the LOCK/
OFF position. The key fob can only be removed from the
ignition when the ignition is in the LOCK/OFF position,
and once removed the shift lever is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position unless the brakes are applied. To move
the shift lever out of the PARK position, the ignition
switch must be turned to the ON/RUN position (engine
running or not) and the brake pedal must be pressed.
Six–Speed Automatic Transmission
(5.7L Engine) — If Equipped
The shift lever position display (located in the instrument
panel cluster) indicates the transmission gear range. Theshift lever is mounted on the right side of the steering
column. You must press the brake pedal to move the shift
lever out of the PARK position (refer to “Brake/
Transmission Shift Interlock System” in this section). To
drive, move the shift lever from PARK or NEUTRAL to
the DRIVE position. Pull the shift lever toward you when
shifting into REVERSE or PARK, or when shifting out of
PARK.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
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.
284 STARTING AND OPERATING
Page 287 of 508

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). Pressing the ERS (-/+) switches on
the shift lever while in the DRIVE position will select the
highest available transmission gear, and will display that
gear in the instrument cluster as 6, 5, 4, 3, 2, 1.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while vehicle is in motion.
Apply the parking brake when leaving vehicle in this
range.When parking on a level surface, you may place the shift
lever in the PARK position first, and then apply the
parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.

WARNING! (Continued)
•Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever clockwise without first pull-
ing it toward you after you have placed it in PARK.
Make sure the transmission is in PARK before
leaving the vehicle.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your foot is firmly pressing the brake pedal.
