Automatic Engine Grade
Braking
Automatic Engine Grade Braking
assists when driving on a downhill
grade. It maintains vehicle speed by
automatically implementing a shift
schedule that uses the engine and
the transmission to slow the vehicle.
The system will automatically
command downshifts to reduce
vehicle speed, until the brake pedal
is no longer being pressed.
While in the Electronic Range
Select (ERS) mode, grade braking
is deactivated, allowing the
driver to select a range and limiting
the highest gear available. Grade
braking is available for normal
driving and in Tow/Haul mode.
SeeAutomatic Transmission
Operation on page 2-24.
Parking Brake
To set the parking brake, hold the
regular brake pedal down, then push
the parking brake pedal down.
If the ignition is on, the brake system
warning light will come on. See
Brake System Warning Light
on page 3-33.Notice:Driving with the parking
brake on can overheat the
brake system and cause
premature wear or damage to
brake system parts. Make
sure that the parking brake is
fully released and the brake
warning light is off before driving.
To release the parking brake,
hold the regular brake pedal down,
then push down momentarily on
the parking brake pedal until
you feel the pedal release. Slowly
pull your foot up off the park
brake pedal. If the parking brake is
not released when you begin to
drive, the brake system warning light
will be on and a chime will sound
warning you that the parking
brake is still on.
If you are towing a trailer and are
parking on a hill, seeTowing a
Trailer on page 4-24.
Features and Controls 2-27
Torque Lock
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 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
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
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 5-28for more information.To shift out of P (Park) use the
following:
1. Apply the brake pedal.
2. 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.

Running the Vehicle
While Parked
It is better not to park with the
engine running. But if you ever have
to, here are some things to know.
{CAUTION
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation.
For more information, seeEngine
Exhaust on page 2-30.
{CAUTION
It can be dangerous to get out of
the vehicle if the automatic
transmission shift lever is not fully
in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running unless you have
to. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when you are on
fairly level ground, always set the
parking brake and move the shift
lever to P (Park).
Follow the proper steps to be sure
the vehicle will not move. See
Shifting Into Park on page 2-28.
If parking on a hill and pulling
a trailer, seeTowing a Trailer on
page 4-24.

Programming the Universal
Home Remote System
For questions or help programming
the Universal Home Remote
System, call 1-800-355-3515 or go
to www.homelink.com.
Programming a garage door opener
involves time-sensitive actions,
so read the entire procedure before
starting. Otherwise, the device
will time out and the procedure will
have to be repeated.To program up to three devices:
1. From inside the vehicle, press
and hold down the two outside
buttons at the same time,
releasing only when the Universal
Home Remote indicator light
begins to ash, after 20 seconds.
This step will erase the factory
settings or all previously

Gate Operator and Canadian
Programming
If you have questions or need help
programming the Universal
Home Remote System, call
1-800-355-3515 or go to
www.homelink.com.
Canadian radio-frequency laws
require transmitter signals to time
out or quit after several seconds of
transmission. This may not be
long enough for Universal Home
Remote to pick up the signal during
programming. Similarly, some
U.S. gate operators are
manufactured to time out in the
same manner.
If you live in Canada, or you are
having difficulty programming a gate
operator or garage door opener
by using the “Programming

lights will be on. The headlamps,
taillamps, sidemarker, and other
lamps will not be on. The instrument
panel and cluster will also not be lit.
When it is dark enough outside, the
DRL lights will turn off and the
headlamps and parking lamps will
turn on. The other lamps that
come on with the headlamps will
also come on.
When it is bright enough outside,
the headlamps will go off and
the DRL will come on.
The regular headlamp system
should be turned on when it is
needed.Adaptive Forward
Lighting System
Vehicles with the Adaptive Forward

If the check engine light comes on
and stays on, while the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem
is apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system
assists the service technician in
correctly diagnosing any
malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle’s fuel economy
might not be as good, and the
engine might not run as
smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.Notice:Modi cations made to
the engine, transmission,
exhaust, intake, or fuel system of
the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle’s emission
controls and can cause this light
to come on. Modi cations to
these systems could lead
to costly repairs not covered by
the vehicle warranty. This
could also result in a failure to
pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications
on page 5-3.
This light comes on during a
malfunction in one of two ways:
Light Flashing:A mis re condition
has been detected. A mis re
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to ash, when it
is safe to do so, stop the vehicle.
Find a safe place to park the vehicle.
Turn the key off, wait at least
10 seconds, and restart the engine. If
the light is still ashing, follow the
previous steps and see your dealer/
retailer for service as soon as
possible.
Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
