SERVICE STABILITY SYSTEM
- 54: If you ever
see the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system (stop; turn off the engine; then start the
engine again). If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem. You
should see your dealer for service. Reduce your speed
and drive accordingly.STABILITY SYSTEM ACTIVE
- 55: You may see
the STABILITY SYSTEM ACTIVE 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 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.
Tire Pressure Status
- 144: If you see the CHECK
TIRE PRESSURE message, you should stop as soon as
you can and check all your tires for damage. (If a tire is
flat, see ªIf a Tire Goes Flatº in the Index.) Also check
the tire pressure in all four tires as soon as you can. See
ªInflation
- Tire Pressureº and ªCheck Tire Pressure
Systemº in the Index.
6-47
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center or the systems monitor
TIRE PRESS light comes on, you should stop as soon as
you can and check all your tires for damage. If a tire is
flat, see ªIf a Tire Goes Flatº in the Index. Also check
the tire pressure in all four tires as soon as you can.
See ªInflation
-Tire Pressureº in the Index.
Any time you adjust a tire's pressure or have one or
more tires repaired or replaced, you'll need to reset
(calibrate) the check tire pressure system. You'll also
need to reset the system whenever you rotate the tires,
buy new tires, install or remove the compact spare, and
whenever the vehicle's battery has been disconnected.
Don't reset the check tire pressure system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the check
tire pressure system will not work properly and may not
alert you when a tire is low or high.
To reset (calibrate) the system with a Driver Information
Center (DIC):
1. Turn the ignition switch to ON.
2. Using the MODE and SELECT buttons, change the
DIC to display TIRE PRESSURE.
3. Press and hold the RESET button for about
five seconds.4. The display should change to read TIRE PRESSURE
RESET. If TIRE PRESSURE RESET does not
appear on the display after about five seconds, see
your dealer for service.
5. When you release the button after seeing the TIRE
PRESSURE RESET message, the display will
change to read TIRE PRESSURE NORMAL.
To reset (calibrate) the system with a systems monitor:
1. Turn the ignition switch to ON.
2. Press and hold the TIRE PRESS RESET button for
about five seconds.
3. The TIRE PRESS light on the systems monitor
should begin to flash. If the TIRE PRESS light does
not begin to flash after about five seconds, see your
dealer for service.
4. Release the TIRE PRESS RESET button and the
system should reset The TIRE PRESS light will
go out.
The system completes the calibration process during
driving. Calibration time can take 45 to 90 minutes,
depending on your driving habits. After the system has
been calibrated, the system will alert the driver that a tire
is low, up to a maximum speed of 65 mph (105 km/h).
6-48 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don't include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire
-Loading
Information label. Reset the Check Tire Pressure
System. See ªCheck Tire Pressure Systemº in the Index.
Make certain that all wheel nuts are properly tightened.
See ªWheel Nut Torqueº in the Index.
CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later, if
you need to, to get all the rust or dirt off.
See ªChanging a Flat Tireº in the Index.
