iv Preface

Then, see if you can move the shift
lever away from P (Park) without
rst pressing the shift lever button.
If you can, it means that the
shift lever was not fully locked into
P (Park).
Torque lock is when the weight of
the vehicle puts too much force
on the parking pawl in the
transmission. This happens when
parking on a hill and shifting
the transmission into P (Park) is
not done properly and then it
is difficult to shift out of P (Park).
To prevent torque lock, set the
parking brake and then shift into
P (Park). To nd out how, see
“Shifting Into P (Park)” listed
previously.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so
you can shift out of P (Park).Shifting Out of Park
(Automatic
Transmission)
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal
unless the shift lever is in P (Park)
with the shift lever button fully
released, and
Prevent movement of the shift
lever out of P (Park) unless
the ignition is in ON/RUN or
ACC/ACCESSORY and the
regular brake pedal is applied.
The shift lock release is always
functional except in the case of
a an uncharged or low voltage
(less than 9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. SeeJump Starting on
page 5-34for more information.To shift out of P (Park):
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the
desired position.
If you still are unable to shift out
of P (Park):
1. Fully release the shift lever
button.
2. While holding down the brake
pedal, press the shift lever
button again.
3. Move the shift lever to the
desired position.
If you still cannot move the shift
lever from P (Park), consult your
dealer/retailer or a professional
towing service.

Electric Power
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery’s temperature and
state of charge. It then adjusts the
voltage for best performance
and extended life of the battery.
When the battery’s state of charge
is low, the voltage is raised
slightly to quickly bring the charge
back up. When the state of charge is
high, the voltage is lowered
slightly to prevent overcharging. If
the vehicle has a voltmeter gage or
a voltage display on the Driver
Information Center (DIC), you may
see the voltage move up or
down. This is normal. If there is a
problem, an alert will be displayed.
The battery can be discharged
at idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fastenough at idle to produce all the
power that is needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator’s
output and the vehicle’s electrical
needs. It can increase engine
idle speed to generate more power,
whenever needed. It can temporarily
reduce the power demands of
some accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,this action may be noticeable to the
driver. If so, a Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If this message is displayed, it is
recommended that the driver reduce
the electrical loads as much as
possible. SeeDIC Warnings and
Messages on page 3-37.
Battery Run-Down
Protection
This feature shuts off the dome
lamp if it is left on for more
than 20 minutes when the ignition is
in LOCK/OFF. This helps to
prevent the battery from being
drained.
Instrument Panel 3-17

If, after several seconds, both status
indicator lights remain on, or if
there are no lights at all, there may
be a problem with the lights or
the passenger sensing system. See
your dealer/retailer for service.
{CAUTION
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
the vehicle serviced right away.
SeeAirbag Readiness Light on
page 3-25for more information,
including important safety
information.
Charging System Light
This light comes on briey when the
ignition key is turned, but the
engine is not running, as a check to
show it is working.
It should go out once the engine
starts. If it stays on, or comes
on while driving, there could be a
problem with the charging system. A
charging system message in the
Driver Information Center (DIC) may
also appear. SeeDIC Warnings
and Messages on page 3-37
for more information. This light could
indicate that there are problems
with a generator drive belt, or that
there is an electrical problem.
Have it checked right away. If the
vehicle must be driven a short
distance with the light on, turn off all
the accessories, such as the
radio and air conditioner.
Up-Shift Light
The vehicle may have an up-shift
light.
When this light comes on, shift to
the next higher gear if weather,
road, and traffic conditions allow.
SeeManual Transmission Operation
on page 2-22for more information.
Brake System Warning
Light
The vehicle’s hydraulic brake
system is divided into two parts. If
one part is not working, the
other part can still work and stop
the vehicle. For good braking
though, both parts need to be
working well.

Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle’s radio.
This interference may occur when
making or receiving phone calls,
charging the phone’s battery,
or simply having the phone on. This
interference causes an increased
level of static while listening to
the radio. If static is received while
listening to the radio, unplug the
cellular phone and turn it off.
Fixed Mast Antenna
The xed mast antenna can
withstand most car washes without
being damaged as long as it is
securely attached to the base. If the
mast becomes slightly bent,
straighten it out by hand. If the mast
is badly bent, replace it.
Occasionally check to make sure
the antenna is tightened to its base.
If tightening is required, tighten
by hand. until fully seated plus one
quarter turn.
XM™ Satellite Radio
Antenna System
The XM Satellite Radio antenna is
located on the roof of the vehicle.
Keep the antenna clear of
obstructions for clear radio
reception.
If the vehicle has a sunroof, the
performance of the XM system may
be affected if the sunroof is open.
Instrument Panel 3-63

The trailer towing harness contains
the following seven trailer circuits:
Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn
Signal
Brown: Taillamps
White: Ground
Light Green: Back-up Lamps
Red: Battery Feed
Dark Blue: Trailer Brake
If charging a remote (non-vehicle)
battery, turn on the headlamps
to boost the vehicle system voltage
to properly charge the battery.Four-Wire Harness Adapter
If towing a light-duty trailer with a
standard four-way, at pin
connector, an adapter is available
from your dealer/retailer.
Hold the adapter with the tab
pointing up.Connect the adapter to the
seven-pin universal heavy-duty
trailer connector attached to
the bracket on the hitch platform.
The ip cap on the vehicle’s harness
locks onto the tab and helps hold
the adapter in place. Plug the
four-way pin connector onto the
