wheel, to operate the windshield wipers.
9(Off):Move the lever to this position to turn off the
windshield wipers.
&(Intermittent; Speed Sensitive Wipers):Move the
lever to this position for intermittent or speed sensitive
operation. When you select this position, the delay
will vary depending on the vehicles speed, as well as,
the manually selected delay.
x(Delay):When the lever is in the intermittent
position, turn the intermittent adjust band with this
symbol on it up or down to set for a shorter or longer
delay between wipes. To the left of the adjust band are
bars, increasing in size from bottom to top, that
indicate the frequency of the wipes. Smaller bars mean
the wipers movement is less frequent. Larger bars
mean the movement is more frequent.

Low-Prole Performance Tire (GTP)
If your vehicle has P225/50R18 94W size tires, they are
classied as “low-prole performance” tires. These
tires are designed for very responsive driving on wet or
dry pavement. You may also notice more road noise
with low-prole performance tires and that they tend to
wear faster.
Notice:If your vehicle has low-prole tires, they
are more susceptible to damage from road hazards
or curb impact than standard prole tires. Tire
and/or wheel assembly damage can occur when
coming into contact with road hazards like,
potholes, or sharp edged objects, or when sliding
into a curb. Your GM warranty does not cover
this type of damage. Keep tires set to the correct
ination pressure and, when possible avoid contact
with curbs, potholes, and other road hazards.For cold weather driving conditions, you may prefer to
get tires designed for snow or ice. See your dealer
for details regarding winter tire availability and proper
tire selection. Also, seeBuying New Tires on page 5-68.
If you choose to use winter tires:
Use tires of the same brand and tread type on
all four wheel positions.
Use only radial ply tires of the same size,
load range, and speed rating as your original
equipment tires.
Winter tires with the same speed rating as your original
equipment tires may not be available for H, V, W
and ZR speed rated tires. If you choose winter tires with
a lower speed rating, never exceed the tire’s maximum
speed capability.

Tire Size
The following illustration shows an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as
the rst character in the tire size means a passenger
vehicle tire engineered to standards set by the U.S. Tire
and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.(C) Aspect Ratio:A two-digit number that indicates the
tire height-to-width measurements. For example, if
the tire size aspect ratio is 60, as shown in item C of
the illustration, it would mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire.
The letter R means radial ply construction; the letter D
means diagonal or bias ply construction; and the
letter B means belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters represent
the load range and speed rating of the tire. The load
index represents the load carry capacity a tire is certied
to carry. The load index can range from 1 to 279. The
speed rating is the maximum speed a tire is certied
to carry a load. Speed ratings range from A to Z.
5-61

{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 needed, to get
all the rust or dirt off. SeeChanging a Flat Tire
on page 5-74.
When It Is Time for New Tires
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need a new tire if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
cannot be repaired well because of the size or
location of the damage.
5-67

Buying New Tires
To nd out what kind and size of tires your vehicle
needs, look at the tire and loading information label. For
more information about this label and its location on
your vehicle, seeLoading Your Vehicle on page 4-33.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specication (TPC Spec)
number on each tire’s sidewall. When you get new
tires, GM recommends that you get tires with that same
TPC Spec number. That way your vehicle will continue
to have tires that are designed to give proper endurance,
handling, speed rating, load range, traction, ride and
other things during normal service on your vehicle.
If your tires have an all-season tread design, the TPC
number will be followed by an “MS” (for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different
sizes, brands, or types (radial and bias-belted
tires), the vehicle may not handle properly,
and you could have a crash. Using tires of
different sizes, brands, or types may also
cause damage to your vehicle. Be sure to
use the correct size, brand, and type of tires
on all wheels. It is all right to drive with
your compact spare temporarily, as it was
developed for use on your vehicle. See
Compact Spare Tire on page 5-86.
5-68

{CAUTION:
If you use bias-ply tires on your vehicle,
the wheel rim anges could develop cracks
after many miles of driving. A tire and/or
wheel could fail suddenly, causing a crash.
Use only radial-ply tires with the wheels on
your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
handling characteristics and resistance to rollover.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable level
of performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will
crash and suffer serious injury. Only use
GM specic wheel and tire systems developed
for your vehicle, and have them properly
installed by a GM certied technician.
SeeBuying New Tires on page 5-68andAccessories
and Modications on page 5-3for additional information.

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has been
used or how far it has been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Tire Chains
{CAUTION:
Do not use tire chains, there is 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, re-adjust or remove the
device if is contacting your vehicle, and do
not spin your wheels.
If you do nd traction devices that will t,
install them on the front tires.

The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire as soon
as you can. SeeCompact Spare Tire on page 5-86.
See the storage instructions label to replace your
compact spare into your trunk properly.
GTP and Retractable Hardtop Models
To store the at tire and jack in the compact spare
tire compartment, do the following:
1. Ensure the retractable hardtop is in the up position.
2. Open the trunk. SeeTrunk on page 2-14for
more information.
3. If you have a retractable hardtop model, unlatch the
trunk cargo cover so that it is in the open position.
4. Remove the bolt extension (in the yellow sleeve)
from the jack and remove the center cap from the
wheel.5. Place the jack over the bolt (B) on the oor, making
sure it contacts the bolt as shown.
6. Place the extension bolt (A) onto the bolt (B).
7. Thread the jack retainer nut (C) until it is at or near
the end of the threads.

Compact Spare Tire
Although the compact spare tire was fully inated when
your vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inated. 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 nish your trip and have your full-size
tire repaired or replaced where you want. 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, do
not take your vehicle 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.
