{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 7-14.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected, an
airbag can still in ate during improper service.
You can be injured if you are close to an
airbag when it in ates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is quali ed to do so.

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. SeeTowing a
Trailer on page 4-30for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

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). SeeShifting Into PARK (P) on
page 2-36. If you are pulling a trailer, see
Towing a Trailer on page 4-30.

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If you
need more power for passing, and you are:
Going less than 35 mph (56 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (56 km/h) or more, push the
accelerator all the way down.
Notice:If your vehicle seems to accelerate slowly
or not shift gears when you go faster, and you
continue to drive your vehicle that way, you could
damage the transmission. Have your vehicle
serviced right away. You can drive in LOW (L) when
you are driving less than 35 mph (56 km/h) and
DRIVE (D) for higher speeds until then.
LOW (L):This position gives you access to gear
ranges. This provides more engine braking but lower
fuel economy than DRIVE (D). You can use it on
very steep hills, or in deep snow or mud.
Electronic Range Select Mode
Electronic Range Selector (ERS) mode allows you to
choose the top-gear limit of the vehicle’s transmission
and the vehicle’s speed while driving down hill or towing
a trailer.
To use this feature, do the following:
1. Move the shift lever to LOW (L).
2. Press the plus/minus
button located on the
shift lever, to increase
or decrease the
gear range available
based upon your
current driving
conditions and needs.

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. SeeTow/Haul
ModeunderTowing a Trailer on page 4-30for
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 2-30.

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 3-47.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 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, see
Towing a Trailer on page 4-30.
