2005 CADILLAC CTS V Owners Manual

{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) on page 5-76for more
information.
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.
5-73

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.
If a Tire Goes Flat
It is unusual for a tire to “blowout” while you’re driving,
especially if you maintain your tires properly. See
Tires on page 5-54. If air goes out of a tire, it’s 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.
5-74

If a tire goes at, and your vehicle has a spare tire,
seeChanging a Flat Tire (CTS) on page 5-76.
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.
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. Don’t 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.
5-75

SeeRun-Flat Tires (CTS-V) on page 5-61andTire
Pressure Monitor System (CTS-V) on page 5-65,
for additional information.
{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.
To order a service manual seeService Publications
Ordering Information on page 7-11.
Changing a Flat Tire (CTS)
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).
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.
5-76

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
the jack and change a tire.Removing the Spare Tire and
Tools (CTS)
The equipment you will need is in the trunk.
To gain access to the spare tire and jacking equipment,
do the following:
1. Turn the center nut on
the compact spare tire
cover counterclockwise
to remove it. Then
remove the cover.
5-77

2. Turn the nut holding the jack counterclockwise and
remove it. Then remove the jack and wheel wrench.
3. Remove the compact spare tire. SeeCompact
Spare Tire (CTS) on page 5-85for more
information about the compact spare tire.4. The tools you will be using next include the jack (A)
and the wheel wrench (B).
5-78

Removing the Flat Tire and
Installing the Spare Tire (CTS)
If your vehicle has wheel covers, use the at end of the
wheel wrench to remove the covers. Turn the wheel
wrench clockwise to gently pry off the wheel cover.
Be careful not to scratch the aluminum wheel edge and
do not try to remove the wheel cover with your hands.If your vehicle has wheel nut caps, turn the wheel
wrench counterclockwise to remove the caps.
5-79

Once the wheel cover and wheel nut caps have been
removed, use the following steps to remove the at tire
and install the spare tire.
1. Place the wheel wrench (A) securely over the wheel
nut (B). Turn the wheel wrench counterclockwise to
loosen all the wheel nuts. Do not remove them yet.2. Find the jacking location using the diagram above
and corresponding hoisting notches located in the
plastic molding. The notches in the plastic molding
are marked with a triangle shape to help you
nd them.
The front location (A) is about 14 inches (35.6 cm)
from the rear edge of the front wheel well, and
the rear location (B) is about 7 inches (17.8 cm)
from the front edge of the rear wheel well.
