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. You do
not want the system to inate while someone is
working on your vehicle. Your dealer 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 544.
{CAUTION:
For up to 10 seconds after the ignition
key is turned off and the battery is
disconnected, an airbag can still inate
during improper service. You can be
injured if you are close to an airbag when
it inates. 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 qualied to do so.
The airbag system does not need regular
maintenance.

Automatic Door Lock
All of the doors will lock automatically when you
move the shift lever out of PARK (P). This feature
cannot be disabled.
If someone needs to get out of the vehicle while it
is not in PARK (P), shift into PARK (P), or,
have that person use the manual lever or the
power door lock switch. When the door is closed
again, it will lock when the vehicle exceeds
5 mph (8 km/h).

the doors at any time, either manually or by
using the power door lock switches.
Programmable Automatic Door
Unlock
Your vehicle was programmed so that all doors
will unlock automatically when the shift lever
is moved into PARK (P).
To change the way the automatic door unlocking
operates, seeDIC Vehicle Personalization
(Uplevel Only) on page 249.
Lockout Protection
The lockout protection feature makes it more
difficult to lock the key in the vehicle. If the driver’s
door is open while the key is in the ignition, the door
cannot be locked with the power door lock switch.
This feature cannot guarantee that you will never be
locked out of the vehicle. If the key is not left in the
ignition, or, if the manual door lock is used, the key
could still be locked inside the vehicle. Always
remember to take the key with you.
Dual Sliding Doors

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:
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
your 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 386for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.

Automatic Transaxle Operation
Maximum engine speed is limited when you are in
PARK (P) or NEUTRAL (N), to protect driveline
components from improper operation.
There are several different positions for your shift
lever.
PARK (P):This gear position locks your front
wheels. It is the best position to use when you start
your engine because your vehicle cannot move
easily.
Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transaxle shift lock control system. You
must fully apply your regular brakes rst and
then press the shift lever button before you can
shift from PARK (P) when the ignition key is
in RUN. If you cannot shift out of PARK (P), easepressure on the shift lever and push the shift lever
all the way info PARK (P) as you maintain
brake application. Then press the shift lever button
and move the shift lever into another gear. See
Shifting Out of Park (P) on page 139.
{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 138.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 386.
133

REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage
the transaxle. 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
transaxle, seeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 377.
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) while the engine is running at
high speed may damage the transaxle.
The repairs would not be covered by your
warranty. Be sure the engine is not running at
high speeds when shifting your vehicle.
134

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 (55 km/h), push
your accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
The vehicle will shift down to the next gear
and have more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see Skidding
underLoss of Control on page 362
Notice:If your vehicle seems to start up
rather slowly or not shift gears when you go
faster, and you continue to drive your vehicle
that way, you could damage the transaxle.
Have your vehicle serviced right away. You can
drive in SECOND (2) when you are driving
less than 35 mph (55 km/h) and DRIVE (D) for
higher speeds until then.
Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when
the outside temperature is 35°F (2°C) or colder.
You may notice that the transaxle will shift at
a higher vehicle speed until the engine is warmed
up. This is a normal condition designed to
provide heat to the passenger compartment and
defrost the windows more quickly. SeeClimate
Control System on page 193andDual Climate
Control System on page 197for more information.
THIRD (3):This position is also used for normal
driving. It reduces vehicle speed more than
DRIVE (D) without using your brakes. You might
choose THIRD (3) instead of DRIVE (D) when
driving on hilly, winding roads, when towing
a trailer, so there is less shifting between gears
and when going down a steep hill.
135

Parking Brake
The parking brake is
located under the
instrument panel on the
driver’s side of the
vehicle.
To set the parking brake, hold the regular brake
pedal down with your right foot and push down on
the parking brake pedal with your left foot.If the ignition is on, the brake system warning light
will come on. SeeBrake System Warning Light
on page 214.
To release the parking brake, hold the regular
brake pedal down with your right foot while
you push down on the parking brake pedal with
your left foot. When you lift your left foot from the
parking brake pedal, it will pop up to the
released position.
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.
If you are towing a trailer and are parking on any
hill, seeTowing a Trailer on page 386.
