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. Do not exceed
5,000 engine rpm. 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 4-28for 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 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 the 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.
CAUTION: (Continued)
CAUTION: (Continued)
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)
(Automatic Transmission) on page 2-32.Ifyou
are pulling a trailer, seeTowing a Trailer on
page 4-28.
Make sure the shift lever is fully in PARK (P) before
starting the engine. 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) while
the ignition key is in ON/RUN. 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. Press the shift lever button and
then move the shift lever into another gear. SeeShifting
Out of PARK (P) on page 2-34later in this section. SE Model
GT and GXP Models

THIRD (3):This position, available on the SE model, is
also used for normal driving. However, it reduces
vehicle speed more than DRIVE (D) without using your
brakes. Here are some times 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.
When going down a steep hill.
LOW (L):This position, available on the SE model,
reduces vehicle speed more than THIRD (3) without
using your brakes. You can use LOW (L) on hills. It can
help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
You can use LOW (L) on very steep hills, or in deep
snow or mud. If the shift lever is put in LOW (L),
the transmission will not shift into rst gear until the
vehicle is going slowly enough.
Notice:Driving in LOW (L) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
LOW (L) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or DRIVE (D)
instead of LOW (L).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 your 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 MODE (M):This position, available on the
GT/GXP models, allows you to change gears similar to a
manual transmission. If your vehicle has this feature,
see Manual Shift Mode (MSM) following.
Manual Shift Mode (MSM) (Automatic
Transmission)
To use this feature, do the following:
1. Move the shift lever from DRIVE (D) rearward and
then to the right into the MANUAL MODE (M).
While driving in manual shift mode, the transmission
will remain in the driver gear selected.
2. Press the shift level forward to upshift or rearward
to downshift.
The odometer display on the instrument panel cluster
will change from the vehicle’s mileage to the letter M, for
manual shift mode, and a number indicating the
requested gear range when moving the shift lever
forward or rearward. SeeSpeedometer and Odometer
on page 3-29for more information.
2-29

While using the MSM feature the vehicle will have rmer
shifting and sportier performance. You can use this
for sport driving or when climbing hills to stay in gear
longer or to downshift for more power or engine braking.
The transmission will only allow you to shift into gears
appropriate for the vehicle speed and engine revolutions
per minute (RPM):
The transmission will not automatically shift to the
next higher gear if the engine RPM is too high.
The transmission will not allow shifting to the next
lower gear if the engine RPM is too high.
If the vehicle does not respond to a gear change, or
detects a problem with the transmission, the range
of gears may be reduced and the Malfunction Indicator
Lamp will come on. SeeMalfunction Indicator Lamp
on page 3-38for more information.
SECOND (2)/THIRD (3) Gear Start
Feature
Notice:If you attempt a third gear start while
trailering or towing a heavy load, you will notice
reduced engine power. This could overheat
and damage your transmission. Do not attempt a
third gear start while trailering or towing your
vehicle.
If your vehicle has the 6-speed transmission, when
accelerating your vehicle from a stop in snowy and icy
conditions, you may want to shift into SECOND (2),
or THIRD (3) gear. A higher gear, and light application
of the gas pedal, may allow you to gain more traction
on slippery surfaces.
With the MSM, the vehicle can accelerate from a stop in
SECOND (2) or THIRD (3).
1. Move the shift lever from DRIVE (D) into the
MANUAL MODE (M) position.
2. With the vehicle stopped, move the lever forward
towards the plus (+) to select SECOND (2) or
THIRD (3)gear. The vehicle will start from a stop
position in SECOND (2) or THIRD (3) gear.
3. Once the vehicle is moving select the desired
drive gear.

Parking Brake
To set the parking brake, pull up on the parking brake
handle. If the ignition is on, the brake system warning
light will come on. SeeBrake System Warning Light on
page 3-34.To release the parking brake:
1. Hold the brake pedal down.
2. Pull the parking brake handle up until you can
press the release button.
3. Hold the release button in as you move the brake
handle all the way down.
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 you are parking on a hill,
seeTowing a Trailer on page 4-28.

Shifting Into PARK (P) (Automatic
Transmission)
{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 4-28.Use this procedure to shift into PARK (P):
1. Hold the brake pedal down with your right foot and
set the parking brake.
SeeParking Brake on page 2-31for more
information.
2. Move the shift lever into PARK (P) by holding in the
button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. For vehicles with base ignitions, remove the key
and take it with you. If you can leave your vehicle

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 under
Engine Exhaust on page 2-35.
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 4-15.
{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) (Automatic
Transmission) on page 2-32.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-28.

This light comes on, as a check to show it is working,
when the ignition is turned ON/RUN but the engine is not
running. If the light does not come on, have it repaired.
This light also comes on during a malfunction in
one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and could damage the emission control system on
your vehicle. Diagnosis and service might be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service might be required.
If the Light is Flashing
The following can prevent more serious damage to your
vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops ashing and remains on steady, see “If
the Light Is On Steady” following.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 ignition off, wait at least 10 seconds, and restart
the engine. If the light remains on steady, see “If the
Light Is On Steady” following. If the light is still ashing,
follow the previous steps and see your dealer/retailer
for service as soon as possible.
If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling the Tank on page 5-9. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap allows fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed should
turn the light off.
Did you just drive through a deep puddle of water?
If so, your vehicle’s electrical system might be wet. The
condition is usually corrected when the electrical system
dries out. A few driving trips should turn the light off.
