Starting and Operating Your
VehicleNew Vehicle Break-InNotice:The 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 first 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
•
Avoid making hard stops for the first 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 5-28for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

Automatic Transmission OperationThe automatic transmission has a shift lever on the
steering column or on the console between the seats.
There is a display, located on the instrument panel
cluster that will indicate the gear the vehicle is in.
Maximum engine speed is limited on automatic
transmission vehicles while in P (Park) or N (Neutral) to
protect driveline components from improper operation.
There are several different positions for the shift lever.
P (Park):This position locks the front wheels. It is
the best position to use when the engine is started
because the vehicle cannot move easily.
{
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 5-28.
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 brakes first, then press the shift lever
button before you can shift from P (Park) while the
ignition is in ON/RUN. If you cannot shift out of P (Park),
ease pressure on the shift lever and push the shift
lever all the way into P (Park) as you maintain brake
application. Then press the shift lever button and move
the shift lever into another gear. SeeShifting Out of
Park on page 3-29.
3-24

Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 5-11.
Notice:Driving the vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have the
vehicle serviced right away. You can drive in
2 (Second) when you are driving less than 35 mph
(55 km/h) and D (Drive) for higher speeds until then.
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, 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) on hills. It can help control vehicle speed
as you go down steep mountain roads. You would also
want to use the brakes off and on.Notice:Driving in 2 (Second) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
2 (Second) at speeds above 65 mph (105 km/h)
can cause damage. Drive in 3 (Third) or D (Drive)
instead of 2 (Second).
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 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.
3-26

Parking BrakeThe parking brake 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 down the parking brake pedal.To release the parking brake, hold the brake pedal
down and push the parking brake pedal. When you lift
your foot off the parking brake pedal, the pedal will
follow it to the released position.
A warning chime will sound and a brake warning light
located on the instrument panel cluster will come
on, if the parking brake is set, the ignition is on and
the vehicle speed is greater than 8 km/h (5 mph).
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 parking on any hill, see
Towing a Trailer on page 5-28.

Running the Vehicle While ParkedIt is better not to park with the engine running. But if you
ever have to, here are some things to know.
{
WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
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, see
Engine Exhaust on page 3-31.
{
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 you are
on fairly level ground, always set the parking brake
and move the shift lever to P (Park).
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 3-28.
If parking on a hill and pulling a trailer, seeTowing a
Trailer on page 5-28.

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 4-44.
Battery Run-Down ProtectionThis feature helps prevent the battery from being drained,
if the interior courtesy lamps, reading/map lamps, visor
vanity lamps or trunk lamp are accidentally left on. If any
of these lamps are left on, they automatically turn off after
10 minutes, if the ignition is off. The lamps will not come
back on again until one of the following occurs:•
The ignition is turned on.
•
The exterior lamps control is turned off, then on
again.
The headlamps will timeout after 10 minutes, if they are
manually turned on with the ignition on or off.

If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modifications made to the engine,
transmission, exhaust, intake, or fuel system of the
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modifications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6-3.This light comes on during a malfunction in one of
two ways:
Light Flashing:A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
•
Reduce vehicle speed.
•
Avoid hard accelerations.
•
Avoid steep uphill grades.
•
If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still flashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.

Steps for Determining Correct Load Limit1.
Locate the statement “The combined weight of
occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle’s placard.
2.
Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.
3.
Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.
4.
The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be five 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400−750 (5 x 150) = 650 lbs).
5.
Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated in
Step 4.
6.
If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity for your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer on page 5-28for important information
on towing a trailer, towing safety rules, and
trailering tips.
