determines the speed to which your vehicle is limited.
Have your vehicle serviced if this message appears.
STABILITY SYS ENGAGED
- 55: You may see
the STABILITY SYS ENGAGED message on the
Driver Information Center. It means that an advanced,
computer
-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or
other slippery spot on the road. When the system is on,
you may hear a noise or feel a vibration in the brake
pedal. This is normal.
When the STABILITY SYS ENGAGED 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
SYS ENGAGED message comes on, you'll know that
something has caused your vehicle to start to spin,
so you should consider slowing down.STARTING DISABLED REMOVE KEY

again. If it still does not start, try another ignition key
or see your dealer for service.

-in
attempt while you were away from your vehicle.
TOP SPEED FUEL CUT
-OFF - 111 : This message
will appear when the Powertrain Control Module (PCM)
detects that the maximum speed for your vehicle has
been reached. The speed of your vehicle will surge as
the fuel supply is cut off. Your vehicle's top speed is
based on the top speed rating of the tires. This ensures
that your vehicle stays in a safe operating range for
the tires.

2-111 Comfort Controls and Radio
System Personalization
These features allow both drivers to personalize their
own climate control settings as well as their radio
settings. For more information, see ªClimate Control
Personalizationº and ªRadio Personalizationº in
the Index.
The outside temperature is always available for display
if it has been selected for a DIC display when your
vehicle is running unless an overriding DIC message
appears. You can change the temperature from
Fahrenheit to Celsius by pressing the ENG/MET
(English/metric) button on the instrument panel.
For more information on the DIC, see ªDIC Messagesº
in the Index.
The electronic sensor can be affected by road or engine
heat during idling, slow driving or when the engine is
first started after a short trip. To ensure proper automatic
climate control operation, the outside air temperature
display may not update as quickly as expected. This is to allow the air surrounding the outside
temperature sensor to be as close to the actual
outside conditions as possible. This is determined
by how much time has elapsed since the vehicle has
been turned off and by vehicle speed.
Continuous Variable Road Sensing
Suspension (CVRSS) -- STS Only
The CVRSS automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through a
computer used to control and monitor the suspension
system. The controller receives input from various
sensors to determine the proper system response.
If the controller detects a problem within the system,
the DIC will display a SERVICE SUSPENSION SYS
message. If this message appears, have your vehicle
serviced at your dealership.

6-41
The vehicle should be properly prepared as follows:

The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall or other
flat surface.

The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.

The vehicle should be placed so it is perpendicular to
the wall or other flat surface.

The vehicle should not have any snow, ice or mud
attached to it.

The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.

The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs. (75 kg) on
the driver's seat.

Tires should be properly inflated.

Start the vehicle and rock it to level the suspension.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.The headlamp aiming devices are under the hood near
the headlamps.
If you believe your headlamps need horizontal
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx

socket or T15 Torx screwdriver.

6-60 Tire Chains
CAUTION:
If your vehicle has P235/55R17 size tires, don't
use tire chains, there's not enough clearance.
Tire chains used on a vehicle without the proper
amount of clearance can cause damage to the
brakes, suspension or other vehicle parts. The
area damaged by the tire chains could cause you
to lose control of your vehicle and you or others
may be injured in a crash.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer's
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it's contacting your vehicle, and don't
spin your wheels.
If you do find traction devices that will fit, install
them on the front tires.
NOTICE:
If your vehicle has a tire size other than
P235/55R17 size tires, use tire chains only where
legal and only when you must. Use only SAE
Class ªSº type chains that are the proper size
for your tires. Install them on the front tires and
tighten them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer's instructions. If you can
hear the chains contacting your vehicle, stop
and retighten them. If the contact continues,
slow down until it stops. Driving too fast or
spinning the wheels with chains on will damage
your vehicle.

Part C: Periodic
Maintenance Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall). You should let your dealer's
service department or other qualified service center
do these jobs. Make sure any necessary repairs are
completed at once.
Proper procedures to perform these services may be
found in a service manual. See ªService and Owner
Publicationsº in the Index.
Steering, Suspension and Front Drive
Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook
-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out
-of-position parts as well as open seams,
holes, loose connections or other conditions which could
cause a heat build
-up in the floor pan or could let
exhaust fumes into the vehicle. See ªEngine Exhaustº
in the Index.
