2004 CADILLAC XLR Owners Manual

{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 a crash. 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.
{CAUTION:
Never use oil or grease on studs or the
threads of the wheel nuts. If you do, the wheel
nuts might come loose and the wheel could
fall off, causing a crash.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become
loose and even come off. This could lead to a
crash. Be sure to use the correct wheel nuts. If
you have to replace them, be sure to get new
GM original equipment wheel nuts.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque speci®cation.

Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can't know how it's been used
or how far it's 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:
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 ®nd traction
devices that will ®t, install them on the
rear tires.
5-68

Lifting Your Vehicle
{CAUTION:
Lifting a vehicle can cause an injury. The
vehicle can slip off the jack and roll over you
or other people. You and they could be badly
injured. Find a level place to lift your vehicle.
To help prevent the vehicle from moving:
1. Set the parking brake ®rmly.
2. Put an automatic transmission shift lever
in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't
move, you can put blocks in front of and
behind the wheels.
{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get
under a vehicle when it is supported only
by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to place
the jack in the proper location before raising
the vehicle.
If you ever use a jack to lift your vehicle, follow the
instructions that came with the jack, and be sure to use
the correct lifting points to avoid damaging your
vehicle.
5-69

Notice:Lifting your vehicle improperly can damage
your vehicle and result in costly repairs not
covered by your warranty. To lift your vehicle
properly, follow the advice in this part.
To help prevent vehicle damage:
·Be sure to place a block or pad between the
jack and the vehicle.
·Make sure the jack you're using spans at least
two crossmember ribs.
·Lift only in the areas shown in the following
pictures.
For additional information, see your dealer and the
Cadillac XLR service manual.

If a Tire Goes Flat
It's unusual for a tire to ªblow outº while you're driving,
especially if you maintain your tires properly. If air
goes out of a tire, it's much more likely to leak out
slowly. See
Tires on page 5-50for additional
information.
Your vehicle, when new, had run-¯at tires. This type of
tire can operate effectively with no air pressure, so
you won't need to stop on the side of the road to change
a ¯at tire. You can just keep on driving. The shorter
the distance you drive and the slower the speed,
the greater the chance that the run-¯at tire will not have
to be replaced. Run-¯at tires perform so well without
any air that a Tire Pressure Monitor (TPM) is used
to alert you if a tire has lost pressure. See
Run-Flat Tires
on page 5-56andTire Pressure Monitor System on
page 5-58.
5-73

{CAUTION:
When the TIRE FLAT MAX SPD 55, REDUCED
HNDLG message is displayed on the Driver
Information Center, your vehicle's handling
capabilities will be reduced during severe
maneuvers. If you drive too fast, you could
lose control of your vehicle. You or others
could be injured. Don't drive over 55 mph
(90 km/h) when the TIRE FLAT MAX SPD 55,
REDUCED HNDLG message is displayed. Drive
cautiously and check your tire pressures as
soon as you can.
If the TPM system detects a tire pressure below 5 psi
(34 kPa), the TIRE FLAT MAX SPD 55, REDUCED
HNDLG warning message is displayed on the Driver
Information Center (DIC). See
DIC Controls and
Displays on page 3-55andDIC Warnings and Messages
on page 3-57for information and details about the
DIC operation and displays.
{CAUTION:
Special tools and procedures are required to
service a run-¯at tire. If these special tools and
procedures aren't used you or others could be
injured and your vehicle could be damaged.
Always be sure the proper tools and
procedures, as described in the service
manual, are used.
Notice:Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in your
run-¯at tires. This damage would not be covered
by warranty. Don't use liquid sealants in your
run-¯at tires.
To order a service manual, see
Service Publications
Ordering Information on page 7-11.
If a tire goes ¯at, the stability control system will turn on
automatically even if it was disabled by the driver.
When a ¯at tire condition exists the Stabilitrak
žsystem
cannot be turned off. SeeStabilitrakžSystem on
page 4-11.
