Use this rotation pattern if
the vehicle has different
size tires on the front
and rear.
Different tire sizes should
not be rotated front
to rear.Use this rotation pattern
when rotating tires of the
same size installed on all
four wheel positions.
Adjust the front and rear
tires to the recommended
inflation pressure on the
Tire and Loading
Information label after the
tires have been rotated.
See Tire Pressure0422
and
Vehicle Load Limits 0255. Reset the Tire Pressure
Monitor System. See Tire

Check that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
Capacities and
Specifications 0480.
{Warning
Rust or dirt on a wheel,
or on the parts to which it
is fastened, can cause
wheel nuts to become
loose over time. The
wheel could come off and
cause a crash. When
changing a wheel, remove
any rust or dirt from
places where the wheel
attaches to the vehicle. In
an emergency, a cloth or
paper towel can be used;

Tire Chains
{Warning
If the vehicle has
235/40R18, 235/35R19,
255/35ZR18, or
275/35ZR18 size tires, 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
loss of control and a crash.
Use another type of traction
device only if its
manufacturer recommends
it for the vehicle's tire size
combination and road
conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage,
drive slow and readjust or
remove the traction device if(Continued)
Warning (Continued)
it contacts the vehicle. Do
not spin the wheels.
If traction devices are used,
install them on the rear tires.
Caution
If the vehicle is equipped
with a tire size other than
235/40R18, 235/35R19,
255/35ZR18, or
275/35ZR18, use tire chains
only where legal and only
when necessary. Use low
profile chains that add no
more than 12 mm thickness
to the tire tread and inner
sidewall. Use chains that are
the proper size for the tires.
Install them on the tires of
the rear axle. Don't use
chains on the tires of the
front axle. Tighten them as
tightly as possible with the
ends securely fastened.
Drive slowly and follow the(Continued)
Caution (Continued)
chain manufacturer's
instructions. If the chains
contact the vehicle, stop and
retighten them. If the
contact continues, slow
down until it stops. Driving
too fast or spinning the
wheels with chains on will
damage the vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow
out while driving, especially if
the tires are maintained
properly. If air goes out of a
tire, it is much more likely to
leak out slowly. See Tires
0413 for additional
information. But if there ever
is a blowout, here are a few
tips about what to expect and
what to do:
If a front tire fails, the flat tire
creates a drag that pulls the
vehicle toward that side. Take
your foot off the accelerator
pedal and grip the steering

After starting the disabled
vehicle and removing the
jumper cables, allow it to idle
for several minutes.
Towing the
Vehicle
Transporting a
Disabled Vehicle
(Electronic Shifter)
Caution
Incorrectly transporting a
disabled vehicle may cause
damage to the vehicle. Use
proper tire straps to secure
the vehicle to the flatbed
tow truck. Do not strap or
hook to any frame,
underbody, or suspension
component not specified
below. Do not move vehicles
with drive axle tires on the
ground. Damage is not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with an electric parking
brake and/or an electronic
shifter. In the event of a loss
of 12-volt battery power, the
electric parking brake
cannot be released, and the
vehicle cannot be shifted to
N (Neutral). Tire skates or
dollies must be used under
the non-rolling tires to
prevent damage while
loading/unloading the
vehicle. Dragging the vehicle
will cause damage not
covered by the vehicle
warranty.
Caution
The vehicle may be equipped
with a tow eye. Improper use
of the tow eye may cause
damage to the vehicle and is
not covered by the vehicle
warranty. If equipped, use(Continued)
Caution (Continued)
the tow eye to load the
vehicle onto a flatbed tow
truck from a flat road
surface, or to move the
vehicle a very short distance
at a walking pace. The tow
eye is not designed for
off-road recovery. The
vehicle must be in
N (Neutral) with the electric
parking brake released when
using the tow eye.
Contact a professional towing
service if the disabled vehicle
must be transported. GM
recommends a flatbed tow
truck to transport a disabled
vehicle. Use ramps to help
reduce approach angles,
if necessary.
If equipped, a tow eye may be
located near the spare tire or
emergency jack. Do not use
the tow eye to pull the vehicle
from the snow, mud, sand,
or ditch. Tow eye threads may

have right or left-hand
threads. Use caution when
installing or removing the
tow eye.
The vehicle must be in
N (Neutral) and the electric
parking brake must be
released when loading the
vehicle onto a flatbed tow
truck.
.If the vehicle is equipped
with car wash mode and has
12-volt battery power, refer
to“Car Wash Mode” under
Automatic Transmission
(Mechanical Shifter) 0272 or
Automatic Transmission
(Electronic Shifter) 0275 to
place the vehicle in
N (Neutral).
.If the 12-volt battery is dead
and/or the engine will not
start, the vehicle will not
move. Try to jump start the
vehicle. Refer to Jump
Starting - North America
0 447 and if the jump start is
successful, retry the “Car
Wash Mode” procedure.
.If jump starting is
unsuccessful, the vehicle will
not move. Tire skates or
dollies must be used under
the non-rolling tires to
prevent vehicle damage.
V-Series Blackwing Only
Due to low ramp angles on the
V-Series Blackwing, use care
when loading the vehicle onto
a flatbed carrier. Front spring
spacers were provided for
lifting the front suspension if
more clearance is necessary
when towing.
Front Tow Eye
The vehicle is equipped with a
tow eye. Only use the tow eye
to pull the vehicle onto a
flatbed car carrier from a flat
road surface. Do not use the
tow eye to pull the vehicle
from snow, mud, or sand. The
tow eye is located under the
carpet in the trunk.
Carefully open the cover in the
fascia by using the small notch
that conceals the tow eye
socket.

Recreational Vehicle
Towing
Caution
Dolly towing or dinghy
towing the vehicle may
cause damage because of
reduced ground clearance.
Always put the vehicle on a
flatbed truck or trailer.
The vehicle was neither
designed nor intended to be
towed with any of its wheels
on the ground. If the vehicle
must be towed, see
Transporting a Disabled
Vehicle (Electronic Shifter)

456 Vehicle Care
Remove any accessories that
may be damaged or interfere
with the car wash equipment.
Hand Wash
Rinse the vehicle well, before
and after washing, to remove
all cleaning agents completely.
If they are allowed to dry on
the surface, they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel
to avoid surface scratches
and water spotting.
Cleaning Underhood
Components
Caution
Do not power wash any
component under the hood
that has this
esymbol.
This could cause damage to
the vehicle that would not
be covered by the vehicle
warranty. Avoid using solvents or
abrasive cleaners that may
harm underhood components.
GM recommends using only
water to clean underhood
components.
If using a pressure washer,
ensure the following criteria
is met:
.Water pressure must be
kept below 14 000 KPa
(2,000 PSI).
.Water temperature must be
below 80 °C (180 °F).
.A spray nozzle with a
40 degree wide angle spray
pattern or wider must be
used, and must be kept at
least 30 cm (1 ft) away from
all surfaces.
Finish Care
Application of aftermarket
clearcoat sealant/wax
materials is not recommended.
If painted surfaces are
damaged, see your dealer to
have the damage assessed
and repaired. Materials such as calcium chloride and other
salts, ice melting agents, road
oil and tar, tree sap, bird
droppings, chemicals from
industrial chimneys, etc., can
damage the vehicle finish if
they remain on painted
surfaces. Wash the vehicle as
soon as possible. If necessary,
use non-abrasive cleaners that
are marked safe for painted
surfaces to remove foreign
matter.
Occasional hand waxing or
mild polishing should be done
to remove residue from the
paint finish. See your dealer
for approved cleaning
products.
Caution
Do not apply waxes or
polishes to uncoated plastic,
vinyl, rubber, decals,
simulated wood, or matte
paint as damage can occur.
