Windshield Wipers
Use this lever, located on the right side of the
steering 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. The amount of
delay time varies between wiping cycles due to
the delay setting selected or the speed of the
vehicle.
x(Delay):While the lever is in the intermittent
position, turn the intermittent adjust band with
this symbol on it up or down to select a shorter or
longer delay between wiping cycles. 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.
6(Low Speed):Move the lever up to the
rst setting past intermittent, for steady wiping at
low speed.
1(High Speed):Move the lever up to the
second setting past intermittent, for wiping
at a high speed.
8(Mist):Move the lever all the way down to
this position for a single wiping cycle. Hold it there
until the windshield wipers start; then let go.
The windshield wipers stop after one wiping cycle.
If additional wiping cycles are needed, hold the
lever down longer.

(G) Maximum Cold Ination Load
Limit:Maximum load that can be carried and the
maximum pressure needed to support that
load. For information on recommended tire
pressure seeInation - Tire Pressure on page 304
andLoading Your Vehicle on page 242.
Tire Size
The following illustration shows, an example of, a
typical passenger car 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
75, as shown in item C, of the illustration, it would
mean that the tire’s sidewall is 75 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:The service description
indicates the load range and speed rating of a
tire. The load index can range from 1 to 279.
Speed ratings range from A to Z.

How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are
properly inated simply by looking at them. Radial
tires may look properly inated even when they
are under-inated. Check the tire’s ination
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
ination pressure is low, add air until you reach the
recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor System
(TPMS). This system uses radio and sensor
technology to check tire pressure levels. Sensors
are mounted onto each tire and wheel assembly.
The TPMS sensors monitor the air pressure
in your vehicle’s tires and transmit tire pressure
readings to a receiver located in the vehicle.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those 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 your
vehicle’s wheels.
{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.
If you must replace your vehicle’s tires with those
that do not have a TPC Spec number, make
sure they are the same size, load range, speed
rating, and construction type (radial and
bias-belted tires) as your vehicle’s original tires.
Your vehicle’s original equipment tires are listed on
the Tire and Loading Information label. This
label is attached to the vehicle’s center pillar
(B-pillar). SeeLoading Your Vehicle on page 242,
for more information about the Tire and Loading
Information label.

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 braking, ride and handling
characteristics, stability, and resistance to rollover.
Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction control,
and stability control, the performance of these
systems can be affected.{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 Saturn specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
Saturn certied technician.
SeeBuying New Tires on page 312and
Accessories and Modications on page 253for
additional information.

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,
readjust or remove the device if it is
contacting your vehicle, and do not spin
your vehicle’s wheels. If you do nd
traction devices that will t, install them on
the front tires.
If a Tire Goes Flat
Your vehicle has a tire inator kit. There is no
spare tire, no tire changing equipment, and
no place to store a tire.
It is unusual for a tire to blow out while you are
driving, especially if you maintain your tires
properly. SeeTires on page 298. If air goes out of a
tire, it is much more likely to leak out slowly. But, if
you should ever have a blow out, here are a few
tips about what to expect and what to do:
If a front tire fails, the at tire creates a drag that
pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the steering
wheel rmly. Steer to maintain lane position,
and then gently brake to a stop well out of the
traffic lane.
