CADILLAC CTS V 2006 1.G Owners Manual

Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned
and balanced carefully at the factory to give you
the longest tire life and best overall performance.
Adjustments to wheel alignment and tire balancing
will not be necessary on a regular basis. However,
if you notice unusual tire wear or your vehicle pulling to
one side or the other, the alignment may need to be
checked. If you notice your vehicle vibrating when
driving on a smooth road, your tires and wheels may
need to be rebalanced. See your dealer for proper
diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly
rusted or corroded. If wheel nuts keep coming loose,
the wheel, wheel bolts, and wheel nuts should be
replaced. If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.If you need to replace any of your wheels, wheel
bolts, or wheel nuts, replace them only with new
GM original equipment parts. This way, you will be
sure to have the right wheel, wheel bolts, and wheel
nuts for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts, or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire (CTS Only) on page 5-84for
more 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 it is contacting your vehicle,
and do not spin your wheels. If you do nd
traction devices that will t, install them on
the rear tires.
5-78

Lifting Your Vehicle (CTS-V)
{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. Place the shift lever in REVERSE (R)
and rmly apply the parking brake.
2. Turn off the engine.
To be even more certain the vehicle will not
move, you can put blocks in front of and
behind the wheels. Also seeParking Your
Vehicle (Manual Transmission) on page 2-36
andParking Brake on page 2-33for additional
information.
{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.
5-79

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 the jack you are using meets the
weight standards for your vehicle and is in
good working order.
Be sure to place a block or pad between the
jack and the vehicle.
Make sure the jack you are using only contacts
the jacking location lift points and is not leaning
on any other vehicle components such as the
rocker panels, the oor pan, or the stone guard
moldings.
Lift only in the areas shown in the following
pictures.
Lifting From the Front
The front lifting points can be accessed from either side
of your vehicle, behind the front tires.
1. Locate the front lifting points using the diagram
shown above and corresponding triangular-shaped
hoisting notches located in the plastic molding.
The front lifting location is about 14 inches (35.6 cm)
from the rear edge of the front wheel well.
2. Be sure to place a block or pad between the jack
and the vehicle.
3. Lift the vehicle with the jack, making sure the jack
is centered on the front lifting point.
5-80

Lifting From the Rear
The rear lifting points can be accessed from either side
of your vehicle, in front of the rear tires.
1. Locate the rear lifting points using the diagram
shown above and corresponding triangular-shaped
hoisting notches located in the plastic molding.
The rear lifting location is about 7 inches (17.8 cm)
from the front edge of the rear wheel well.2. Be sure to place a block or pad between the jack
and the vehicle.
3. Lift the vehicle with the jack, making sure the jack
is centered on the rear lifting point.

If a Tire Goes Flat
It is unusual for a tire to “blowout” while you are driving,
especially if you maintain your tires properly. See
Tires on page 5-57. If air goes out of a tire, it is much
more likely to leak out slowly. But if you should ever
have a “blowout”, here are a few tips about what
to expect and what to do:
If a front tire fails, the at tire will create 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.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop — well off the road if possible.If a tire goes at, and your vehicle has a spare tire,
seeChanging a Flat Tire (CTS Only) on page 5-84.
This information shows you how to use your vehicle’s
tire changing equipment and how to change a at
tire safely.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and
training. The jack provided with your vehicle
is designed only for changing a at tire.
If it is used for anything else, you or others
could be badly injured or killed if the vehicle
slips off the jack. Use the jack provided with
your vehicle only for changing a at tire.
5-82

Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare tire
and no tire changing equipment. Run-at tires can
operate effectively with no air pressure for a limited
distance and speed. Your vehicle also has a Tire
Pressure Monitor (TPM) which will alert you if there
is a loss of tire pressure in any of the tires. These
tires perform so well without any air pressure that a
Tire Pressure Monitor (TPM) is used to alert you when
there is a low tire condition.
{CAUTION:
When the low tire warning light is displayed on
the instrument panel cluster, 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. Do not drive over
55 mph (90 km/h) when the low tire warning
light is displayed. Drive cautiously and check
your tire pressures as soon as you can.SeeRun-Flat Tires (CTS-V) on page 5-64andTire
Pressure Monitor System on page 5-68, for additional
information.
{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools
and procedures are not 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.
To order a service manual seeService Publications
Ordering Information on page 7-16.

Changing a Flat Tire (CTS Only)
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your
hazard warning ashers.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put an automatic transmission shift lever
in PARK (P), or shift a manual transmission
to FIRST (1) or REVERSE (R).
CAUTION: (Continued)
CAUTION: (Continued)
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
Put the wheel blocks at the front and rear of
the tire farthest away from the one being
changed. That would be the tire on the other
side, at the opposite end of the vehicle.
5-84

When you have a at tire, use the following example as a
guide to assist you in the placement of wheel blocks.
The following information will tell you next how to use
