sounds, it means oil isn't going through the engine
properly. The oil could be low, or there might be some
other oil problem. See your dealer for service.

If you do, your engine can become so hot that
it catches fire. You or others could be burned.

vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

When the STABILITY SYSTEM ACTIVE message
is on, you should continue to steer in the direction you
want to go. The system is designed to help you in bad
weather or other difficult driving situations by making
the most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on,
you'll know that something has caused your vehicle to
start to spin, so you should consider slowing down.
DIC Personal Choice Programming
The DIC can be used to program the following personal
choice features available with your vehicle:

Automatic Door Locks

Window Lockout

Security Feedback

Delayed Locking

Perimeter Lighting

Memory Seats

Tilt Mirrors (If Equipped)

Driver ID ON/OFFFor vehicles not equipped with a DIC, see ªPersonal
Choice Programmingº in the Index.
The personal choice settings displayed on the DIC
are determined by the transmitter used to enter the
vehicle. Each remote keyless entry transmitter was
pre
-programmed to belong to DRIVER 1 or DRIVER 2
and is numbered on the back. After the button with the
unlock symbol on a remote keyless entry transmitter is
pressed and the ignition is in RUN, the DIC will display
the identified driver and recall the settings previously
programmed for that driver. The settings can also be
recalled by briefly pressing one of the MEMORY
buttons located on the driver's door.
If you unlock the vehicle using your door key instead
of your transmitter, the DIC will not change drivers and
will recall the information from the last transmitter used
or the last driver using the memory seat controls. If this
happens and you were not the last driver of the vehicle,
simply press your correct driver number on the memory
seat controls or press the button with the unlock symbol
on your remote keyless entry transmitter.

Winter Driving
Here are some tips for winter driving:

Have your vehicle in good shape for winter.

You may want to put winter emergency supplies in
your trunk.
Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and a
couple of reflective warning triangles. And, if you will
be driving under severe conditions, include a small bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.

4-32
CAUTION:
Things you put inside your vehicle can strike and
injure people in a sudden stop or turn, or in
a crash.

Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can.
Try to spread the weight evenly.

Never stack heavier things, like suitcases,
inside the vehicle so that some of them are
above the tops of the seats.

Don't leave an unsecured child restraint in
your vehicle.

When you carry something inside the
vehicle, secure it whenever you can.
Electronic Level Control
This feature keeps the rear of your vehicle level as the
load changes. It is automatic
-- you do not need to
adjust anything.
Towing a Trailer
CAUTION:
If you don't use the correct equipment and drive
properly, you can lose control when you pull a trailer.
For example, if the trailer is too heavy, the brakes
may not work well
-- or even at all. You and your
passengers could be seriously injured. You may also
damage your vehicle; the resulting repairs would not
be covered by your warranty. Pull a trailer only if you
have followed all the steps in this section. Ask your
dealer for advice and information about towing a
trailer with your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in ªWeight of the Trailerº
that appears later in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.

4-36 Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer's recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Trailer Brakes
Does your trailer have its own brakes? Be sure to read and
follow the instructions for the trailer brakes so you'll be
able to install, adjust and maintain them properly.
Because you have anti
-lock brakes, do not try to tap into
your vehicle's brake system. If you do, both brake
systems won't work well, or at all.
Trailer Wiring Harness
All of the electrical circuits required for your trailer
lighting system can be accessed at the driver's side rear
lamp connector. This connector is located under the
carpet on the rear corner of the trunk compartment.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.

2. If your vehicle has this
aluminum wheel, it may
have plastic wheel nut
caps. Use the wheel nut
wrench to remove the
wheel nut caps and to
loosen the wheel nuts.
3. When reinstalling the decorative nut caps, tighten the
caps snugly with the wheel wrench, then continue
one
-quarter turn to secure plastic caps.
When reinstalling the wheel cover, carefully line up the
tire valve stem and the notch in the wheel cover.
Removing the Flat Tire and Installing the
Spare Tire
1. Use the wheel wrench to loosen the wheel nuts, but
don't remove them yet.
2. The jack has a bolt at the end. Attach the wheel
wrench to the bolt to create a jack handle.

5-26 Storing the Flat Tire and Tools
CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
After you've put the compact spare tire on your vehicle,
you'll need to store the flat tire in your trunk. Use the
following procedure to secure the flat tire in the trunk.
Store the flat tire as far forward in the trunk as possible.
Store the jack and wheel wrench in their compartment in
the trunk.
