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 cmtinue 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
STABiLiiY SYSTEM ACTIVE message comes on, you’!!
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
If a Tire Goes Flat on page 5-72.) Also check
the tire pressure in all four tires as soon as you can.
See
inflation -- lire Pressure on page 5-62 and Check
Tire Pressure System
on page 5-64.
Driver Identifier DIC Display
This feature allows two different drivers to store and
recall their own preferred display mode. The
personalization settings displayed
on the DIC are
determined by the transmitter used to enter the vehicle.
After the uniock button
on a remote keyless entry
transmitter (if equipped) is pressed and the ignition is
in
ON, the DIC will display the identified driver. The
settings can also be changed by briefly pressing one of
the MEMORY buttons located on the driver’s door.
The DIC is used to program information for DRIVER
#I
UNKNOWN DRIVER if they are neither DRIVER #I nor
DRIVER
#2.

Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading information
label found on the rear edge of the driver’s door tells
you the proper size, speed rating and recommended
inflation pressures for the tires on your vehicle. It also
gives you important information about the number
of people that can be in your vehicle and the total weight
that you can carry. This weight is called the Vehicle
Capacity Weight and includes the weight of all
occupants, cargo and all nonfactory-installed options.
THIS VEHICLE CONFORMS
VEHICLE
SAFETY BUMPER
The other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the gross
weight capacity of your vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the Gross
Axle Weight Rating (GAWR) for either the front or
rear axle.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer.
If you ever have questions
about your tire warranty and where to obtain service,
see your
P tiac Warranty booklet for details.
Poorly maintained and improperly used
Overloading your tires can cause
tires are dangerous.
overheating as a result of too much
friction. You could have an air-out and a
serious accident. See ”Loading Your
Vehicle”
in the Index.
Underinflated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued)
Overinflated tires are more likely be
cut, punctured or broken by a sudden impact
- such as when you hit a pothole.
Keep tires at the recommended pressure.
If your tread is badly worn, or if your tires
have been damaged, replace them. See
”Inflation
- Tire Pressure” in this section
for inflation pressure adjustment for higher
speed driving.
Worn, old tires can cause accidents.
Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the rear
edge of the driver’s door, shows the correct inflation
pressures for your tires when they’re cold.
“Cold” means
your vehicle has been sitting for at least three hours
or driven no more than
1 mile (1.6 km).
If you’ll be driving at high speeds (e.g., speeds
of
100 mph (160 km/h) or higher), where it is legal,
set the cold inflation pressure to the maximum
inflation pressure shown on the tire sidewall, or
to
35 psi (244 kPa), whichever is lower.
5-62

See the example below. When you end this high-speed
driving, return to the cold inflation pressure shown on
the Tire-Loading Information label.
Example:
You’ll find maximum load and inflation pressure molded
on the tire’s sidewall, in small letters near the rim
flange. It will read something like this: Maximum load
690
kg (1521 Ibs) @ 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high-speed driving at
35 psi (244 kPa).
Notice: Don’t let anyone tell you that underinflation
or overinflation
is all right. It’s not. If your tires
don’t have enough air (underinflation), you can get
the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy
If your tires have too much air (overinflation), you
can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back
on the valve stems.
They help prevent leaks by keenin9 out dirt and
moisture.
5-63

Check Tire Pressure System
The check tire pressure system can alert you to a large
change in the pressure of one tire. The system won’t
alert you before you drive that a tire is low or flat.
You must begin driving before the system will work
properly.
The CHECK TIRE PRESSURE message will appear on
the Driver Information Center (DIC) or the system
monitor TIRE PRESS light will come on
if pressure
difference (low pressure) is detected in one tire.
The check tire pressure system may not alert you
if:
more than one tire is low,
the vehicle is moving faster than 65 mph (105 km/h),
the system is not yet calibrated,
the compact spare tire is installed,
the tire treadwear is uneven,
tire chains are being used, or
the vehicle is being driven on a rough or
frozen road. If
the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-43.
The check tire pressure system detects differences
in tire rotation speeds that are caused by changes in tire
pressure. The system can alert you about a low
tire
- but it doesn’t replace normal tire maintenance.
See
Tires on page 5-62.
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center (DIC) 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
If a Tire Goes Flat on
page
5-72. Also check the tire pressure in all four tires
as soon as you can. See
Inflation -- Tire Pressure
on page
5-62.
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
and install or remove the compact spare.
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.
5-64

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
Check Tire
Pressure System on page
5-64.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and
Specifications on page
5- 100.
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 “Changing a Flat
Tire”
in the Index.

Compact Spare Tire
Although the compact spare tire was fully inflated when
Check the inflation pressure regularly. It should be
60 psi (420 kPa).
..^..I yuul vehicle was iievi, it mi7 lose air after a tine. After
installing the compact spare on your vehicle, you
should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km)~
so you can finish your trip and have your full-size
tire repaired or replaced where you want. You must:
calibrate the Check Tire Pressure System after installing
or removing the compact spare. See
Check Tire
Pressure
System on page 5-64. Of course, it’s best to
replace your spare with a full-size tire as soon as
you can. Your spare will last longer and be in good
shape in case you need
it again.
Notice: When the compact spare is installed, don’t
take your vehic!e through
an automatic car wash
with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
spare tire and its wheel together.
