250 Driving and Operating
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the
wheels and brake
components, always clear
snow and ice from inside the
wheels and underneath the
vehicle before driving.
Snow or ice between the tires
and the road creates less
traction or grip, so drive
carefully. Wet ice can occur at
about 0 °C (32 °F) when
freezing rain begins to fall.
Avoid driving on wet ice or in
freezing rain until roads can be
treated. For Slippery Road Driving:
.Accelerate gently.
Accelerating too quickly
causes the wheels to spin
and makes the surface under
the tires slick.
.Turn on Traction Control.
See Traction Control/
Electronic Stability Control
0
276.
.Antilock Brake System (ABS)
improves vehicle stability
during hard stops, but the
brakes should be applied
sooner than when on dry
pavement. See Antilock
Brake System (ABS) 0273.
.Allow greater following
distance and watch for
slippery spots. Icy patches
can occur on otherwise clear
roads in shaded areas. The
surface of a curve or an
overpass can remain icy
when the surrounding roads
are clear. Avoid sudden
steering maneuvers and
braking while on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD)
mode. See Driver Mode
Control 0278 and
All-Wheel Drive 0273.
Blizzard Conditions
Stop the vehicle in a safe
place and signal for help. Stay
with the vehicle unless there is
help nearby. Get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine
exhaust under the vehicle.
This may cause exhaust
gases to get inside. Engine
exhaust contains carbon
monoxide (CO), which cannot
be seen or smelled. It can
cause unconsciousness and
even death.

a TPC specification code
molded onto the sidewall.
Original equipment all-season
tires can be identified by the
last two characters of this
TPC code, which will be“MS.”
Consider installing winter tires
on the vehicle if frequent
driving on snow or ice-covered
roads is expected. All-season
tires provide adequate
performance for most winter
driving conditions, but they
may not offer the same level
of traction or performance as
winter tires on snow or
ice-covered roads. See Winter
Tires 0402.
Winter Tires
This vehicle was not originally
equipped with winter tires.
Winter tires are designed for
increased traction on snow
and ice-covered roads.
Consider installing winter tires
on the vehicle if frequent
driving on ice or snow covered
roads is expected. See your
dealer for details regarding winter tire availability and
proper tire selection. Also, see
Buying New Tires
0419.
With winter tires, there may
be decreased dry road
traction, increased road noise,
and shorter tread life. After
changing to winter tires, be
alert for changes in vehicle
handling and braking.
If using 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 the
original equipment tires.
Winter tires with the same
speed rating as the original
equipment tires may not be
available for H, V, W, Y, and ZR
speed rated tires. If winter
tires with a lower speed rating
are chosen, never exceed the
tire's maximum speed
capability.
Tire Sidewall Labeling
Useful information about a
tire is molded into its
sidewall. The examples
show a typical passenger
vehicle tire and a compact
spare tire sidewall.
Passenger Tire Example
(1) Tire Size:The tire size
is a combination of letters
and numbers used to
define a particular tire's
width, height, aspect ratio,
construction type, and

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -

420 Vehicle Care
performance may be
adversely affected if all the
tires are not replaced at
the same time. If proper
rotation and maintenance
have been done, all four
tires should wear out at
about the same time.
However, if it is necessary
to replace only one axle set
of worn tires, place the
new tires on the rear axle.
See Tire Rotation0417.
{Warning
Tires could explode
during improper service.
Attempting to mount or
dismount a tire could
cause injury or death.
Only your dealer or
authorized tire service
center should mount or
dismount the tires.
{Warning
Mixing tires of different
sizes (other than those
originally installed on the
vehicle), brands, tread
patterns, or types may
cause loss of vehicle
control, resulting in a
crash or other vehicle
damage. Use the correct
size, brand, and type of
tire on all wheels.
{Warning
Using bias-ply tires on
the vehicle may cause the
wheel rim flanges to
develop cracks after
many miles of driving.
A tire and/or wheel could
fail suddenly and cause a
crash. Use only radial-ply
tires with the wheels on
the vehicle. Winter tires with the same
speed rating as the original
equipment tires may not be
available for H, V, W, Y and
ZR speed rated tires. Never
exceed the winter tires’
maximum speed capability
when using winter tires
with a lower speed rating.
If the vehicle tires must be
replaced with a tire that
does not have a TPC Spec
number, make sure they
are the same size, load
range, speed rating, and
construction (radial) as the
original tires.
The Tire and Loading
Information label indicates
the original equipment tires
on the vehicle. See Vehicle
Load Limits
0252.

Vehicle Care 421
Different Size Tires
and Wheels
If wheels or tires are installed
that are a different size than
the original equipment wheels
and tires, vehicle performance,
including its braking, ride and
handling characteristics,
stability, and resistance to
rollover may be affected. If the
vehicle has electronic systems
such as antilock brakes,
rollover airbags, traction
control, electronic stability
control, or All-Wheel Drive, the
performance of these systems
can also be affected.
{Warning
If different sized wheels are
used, there may not be an
acceptable level of
performance and safety if
tires not recommended for
those wheels are selected.
This increases the chance of
a crash and serious injury.(Continued)
Warning (Continued)
Only use GM specific wheel
and tire systems developed
for the vehicle, and have
them properly installed by a
GM certified technician.
See Buying New Tires 0419
and Accessories and
Modifications 0363.
Uniform Tire Quality
Grading
The following information
relates to the system
developed by the United
States National Highway
Traffic Safety
Administration (NHTSA),
which grades tires by
treadwear, traction, and
temperature performance.
This applies only to
vehicles sold in the United
States. The grades are
molded on the sidewalls of
most passenger car tires. The Uniform Tire Quality
Grading (UTQG) system
does not apply to deep
tread, winter tires, compact
spare tires, tires with
nominal rim diameters of
10 to 12 inches
(25 to 30 cm), or to some
limited-production tires.
While the tires available on
General Motors passenger
cars and light trucks may
vary with respect to these
grades, they must also
conform to federal safety
requirements and
additional General Motors
Tire Performance Criteria
(TPC) standards.
Quality grades can be
found where applicable on
the tire sidewall between
tread shoulder and
maximum section width.
For example:
