Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
If you have all-wheel drive, keep your
speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles
(805 km). Do not make full-throttle starts.
Avoid downshifting to brake, or slow,
the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
the new brake linings are not yet broken
in. Hard stops with new linings can
mean premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 371for the
trailer towing capabilities of your vehicle
and more information.
Following break-in, engine speed and load can
be gradually increased.
123

Automatic Transmission Operation
Your vehicle has an electronic shift position
indicator within the instrument panel cluster.
When using the Electronic Range Select Mode a
number will display next to the L, indicating
the current gear that has been selected.
See Electronic Range Select mode in this section
for more information.
Your automatic transmission has a shift lever
located on the console between the seats.
PARK (P):This position locks your front wheels. It
is the best position to use when you start your
engine because your vehicle cannot move easily.{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your 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 your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P). See
Shifting Into Park (P) on page 135.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 371.
Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.
129

You must fully apply your regular brake rst and
then press the shift lever button before you
can shift from PARK (P) when the ignition key is in
ON. If you cannot shift out of PARK (P), ease
pressure on the shift lever, then push the
shift lever all the way into PARK (P) as you
maintain brake application. Then press the shift
lever button and move the shift lever into another
gear. SeeShifting Out of Park (P) on page 137.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transmission. The repairs would not be covered
by your warranty. Shift to REVERSE (R) only
after your vehicle is stopped.
To rock your vehicle back and forth to get out of
snow, ice or sand without damaging your
transmission, seeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 360.
NEUTRAL (N):In this position, your engine does
not connect with the wheels. To restart when
you are already moving, use NEUTRAL (N) only.
Also, use NEUTRAL (N) when your vehicle is
being towed.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) with the engine running at high
speed may damage the transmission. The
repairs would not be covered by your warranty.
Be sure the engine is not running at high
speed when shifting your vehicle.
130

Tow/Haul Mode
Your vehicle may have a Tow/Haul mode.
The button to turn it on
or off is located on
instrument panel under
the climate controls.
Push the button to turn it on, push it again to
deactivate the system. You can use this feature to
assist when towing or hauling a heavy load.
When Tow/Haul is activated the Tow/Haul symbol
will come on the instrument panel cluster. See
Tow/Haul ModeunderTowing a Trailer on
page 371for more information.
Automatic Engine Grade Braking
Automatic Engine Grade Braking assists when
driving on a downhill grade. It maintains the
vehicle’s speed by automatically implementing a
shift schedule that uses the engine and the
transmission to slow the vehicle. This reduces
wear on the brakes system and increases control
of the vehicle. The system constantly monitors
the vehicle’s speed, acceleration, throttle position,
and whether the brake pedal is being pressed,
and determines when to keep the current vehicle
speed or to slow down. The system will then
automatically command downshifts that reduces
the vehicle’s speed, until the brake pedal is
no longer being pressed. This indicates the desired
vehicle speed has been reached.
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 129.
133

Parking Brake
To set the parking
brake, push down the
parking brake pedal
down with your left foot.
If the ignition is on, the brake system warning light
will come on. SeeBrake System Warning Light
on page 222.Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify 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 with your right foot. Push down
momentarily on the parking brake pedal with
your left foot until you feel the pedal release, then
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 371.
134

Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 371.1. Hold the brake pedal down with your right foot
and set the parking brake.
2. Move the shift lever into PARK (P) by holding
in the button on the shift lever and pushing
the shift lever all the way toward the front
of the vehicle.
3. Turn the ignition key to OFF.
4. Remove the key and take it with you. If you
can leave your vehicle with the ignition key in
your hand, your vehicle is in PARK (P).
135

Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle could
move suddenly if the shift lever is not fully
in PARK (P) with the parking brake rmly
set. And, if you leave the vehicle with the
engine running, it could overheat and even
catch re. You or others could be injured.
Do not leave your vehicle with the engine
running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and
your parking brake is rmly set before you leave it.
After you have moved the shift lever into PARK (P),
hold the regular brake pedal down. Then, see if you
can move the shift lever away from PARK (P)
without rst pushing the button.
If you can, it means that the shift lever was not
fully locked in PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of
the vehicle may put too much force on the parking
pawl in the transmission. You may nd it difficult to
pull the shift lever out of PARK (P). This is called
“torque lock.” To prevent torque lock, set the
parking brake and then shift into PARK (P) properly
before you leave the driver’s seat. To nd out how,
seeShifting Into Park (P) on page 135.
When you are ready to drive, move the shift lever
out of PARK (P)beforeyou release the parking
brake.
If torque lock does occur, you may need to have
another vehicle push your vehicle a little uphill
to take some of the pressure from the parking pawl
in the transmission, then you will be able to pull
the shift lever out of PARK (P).
136

Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system. You have to apply your
regular brake rst and then press the shift lever
button before you can shift from PARK (P).
SeeAutomatic Transmission Operation on
page 129.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the
way into PARK (P) as you maintain brake
application. Then press the shift lever button and
move the shift lever into the gear you wish.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
137

Running the Engine 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 the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 138.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 356.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your 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 your vehicle will not move,
even when you are on fairly level ground,
always set the parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 135.
If you are pulling a trailer, seeTowing a Trailer on
page 371.
