If the security light comes on and stays on while driving,
the engine will restart if you turn it off. However, the
theft-deterrent system is not working properly and must
be serviced by your dealer/retailer. The vehicle is
not protected by the theft-deterrent system at this time.
In an emergency, contact Roadside Assistance.
SeeRoadside Assistance Program on page 8-7.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run
if you follow these guidelines:
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 5-48for the trailer towing
capabilities of the vehicle and more information.
Following break-in, engine speed and load can
be gradually increased.

Automatic Transmission Operation
The vehicle has a shift lever on the steering column.
It features an electronic shift position indicator within the
instrument cluster. This display is powered anytime
the shift lever is capable of being moved out of P (Park).
This means that if the ignition is turned off, but not in
LOCK/OFF, there will be a small current drain on
the battery which could discharge the battery over a
period of time. If you need to leave the key in the ignition
but not in LOCK/OFF for an extended period, it is
recommended that you disconnect the battery cable
from the battery to prevent discharging the battery.
There are several different positions for the shift lever.
P (Park):This position locks the rear wheels. It is
the best position to use when you start the engine
because the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly 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). SeeShifting Into
Park (Automatic Transmission) on page 3-31.
If you are pulling a trailer, seeTowing a Trailer on
page 5-48.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must fully
apply the brake pedal before you can shift from P (Park)
when the ignition key is in ON/RUN. If you cannot
shift out of P (Park), ease pressure on the shift lever by
pushing the shift lever all the way into P (Park) as
you maintain brake application. Then move the shift
lever into another gear. SeeShifting Out of Park
(Automatic Transmission) on page 3-32.
3-21

3 (Third):This position is also used for normal driving.
However, it reduces vehicle speed more than D (Drive)
without using the brakes. You might choose 3 (Third)
instead of D (Drive) when driving on hilly, winding roads,
or when towing a trailer, so there is less shifting
between gears and when going down a steep hill.
2 (Second):This position reduces vehicle speed even
more than 3 (Third) without using the brakes. You can
use 2 (Second) to help control vehicle speed on
steep mountain roads, but then you would also want to
use the brakes off and on.
1 (First):This position reduces vehicle speed even
more than 2 (Second) without using the brakes. You can
use it on very steep hills, or in deep snow or mud.
If the shift lever is put in 1 (First) while the vehicle is
moving forward, the transmission will not shift into first
gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by the vehicle warranty. If you
are stuck, do not spin the tires. When stopping on a
hill, use the brakes to hold the vehicle in place.Manual Transmission Operation
This is your shift pattern.
Here is how to operate the manual transmission:
1 (First):Press the clutch pedal and shift into 1 (First).
Then, slowly let up on the clutch pedal as you slowly
press down on the accelerator pedal.
You can shift into 1 (First) when you are going less than
20 mph (30 km/h). If you have come to a complete
stop and it is hard to shift into 1 (First), put the shift lever
in Neutral and let up on the clutch. Then press the
clutch pedal back down and shift into 1 (First).
2 (Second):Press the clutch pedal as you let up on the
accelerator pedal and shift into 2 (Second). Then, slowly
let up on the clutch pedal as you press the accelerator
pedal.

Parking Brake
The parking brake pedal is
located to the left of the
brake pedal, near the
driver door.
To set the parking brake, hold the brake pedal down,
then push the parking brake pedal down to its
fully-applied position.
A chime will activate and the brake warning light,
located on the instrument panel, will flash when the
parking brake is applied and the vehicle is moving at
least 3 mph (5 km/h) for at least three seconds.
The chime will deactivate and the light will turn off
when the parking brake is set and the vehicle is moving
below 3 mph (5 km/h). SeeBrake System Warning
Light on page 4-25.To release the parking brake, hold the regular brake
pedal down. Pull the bottom edge of the lever, located
above the parking brake pedal, with the parking brake
symbol, directly rearward to release the parking brake.
If the ignition is on when the parking brake is released,
the brake system warning light will go off.
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.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 5-48.

Shifting Into Park
(Automatic Transmission)
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. 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, use the steps that follow.
If you are pulling a trailer, seeTowing a Trailer on
page 5-48.
1. Hold the brake pedal down with your right foot and
set the parking brake.
SeeParking Brake on page 3-30for more
information.
{WARNING:
If you have four-wheel drive, the vehicle will be free
to roll — even if the shift lever is in P (Park) — if the
transfer case is in Neutral. So, be sure the transfer
case is in a drive gear, two-wheel high (2H) or
four-wheel high (4H) or four-wheel low (4L) — not in
Neutral.
2. Move the shift lever into P (Park) by pulling the
lever toward you and moving it up as far as it
will go.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can
leave the vehicle with the key, the vehicle is in
P (Park).
3-31

The shift lock control system is designed to do the
following:
•Prevent the ignition key from being removed unless
the shift lever is in P (Park).
•Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN and the brake
pedal is applied.
The shift lock control system is always functional
except in the case of a dead battery or low voltage
(less than 9 V) 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 6-43for more information.
To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park):
1. Ease the pressure on the shift lever.
2. While holding down the brake pedal, push the shift
lever all the way into P (Park)
3. Move the shift lever to the desired position.
If you are still having a problem shifting, then have the
vehicle serviced.
Parking the Vehicle
(Manual Transmission)
If the vehicle has a manual transmission, before you get
out of the vehicle, move the shift lever into R (Reverse),
and firmly apply the parking brake. Once the shift
lever has been placed into R (Reverse) with the clutch
pedal pressed in, turn the ignition key to LOCK/OFF,
remove the key and release the clutch.
If you are parking on a hill, or if the vehicle is pulling a
trailer, seeTowing a Trailer on page 5-48.

{WARNING:
Things that can burn could touch hot exhaust
parts under the vehicle and ignite. Do not park
over papers, leaves, dry grass, or other things that
can burn.
3-33

WARNING: (Continued)
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 3-34.
{WARNING:
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 firmly 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 it
is on fairly level ground, always set the parking
brake and move the automatic transmission shift
lever to P (Park), or the manual transmission shift
lever to Neutral.
{WARNING:
Four-wheel drive vehicles with the transfer case
in N (Neutral) will allow the vehicle to roll, even if
the automatic transmission shift lever is in
P (Park). So, be sure the transfer case is in a
drive gear — not in N (Neutral). Always set the
parking brake.
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park (Automatic Transmission)

Dome Lamp Override
The dome lamp override button is located below the
exterior lamps control.
E(Dome Lamp Override):Press this button in to
make the dome lamps remain off when the doors are
open. To return the lamps to automatic operation,
press
Eagain and return it to the out position.
Exit Lighting
The interior lamps will come on when the key is
removed from the ignition. The lamps will not come
on if the dome override button is pressed in.
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 InformationCenter (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 fast enough 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 4-37.
