Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See
the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much
flexing. There could be a
blowout and a serious
crash. See Vehicle Load
Limits 0191.
(Continued)
Warning (Continued)
.Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could
cause serious injury.
Check all tires frequently
to maintain the
recommended pressure.
Tire pressure should be
checked when the tires
are cold.
.Overinflated tires are
more likely to be cut,
punctured, or broken by
a sudden impact —such
as when hitting a pothole.
Keep tires at the
recommended pressure.
.Worn or old tires can
cause a crash. If the
tread is badly worn,
replace them.

364 Vehicle Care
If equipped, carefully open the cover
by using the small notch that
conceals the rear tow eye socket.
Install the tow eye into the socket by
turning it until it stops.
When the tow eye is removed,
reinstall the cover with the notch in
the original position.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
Recreational Vehicle Towing0364.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle –such as behind a motor
home. The two most common types
of recreational vehicle towing are
known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly. Here are some important things to
consider before recreational vehicle
towing:
.
Before towing the vehicle,
become familiar with the local
laws that apply to recreational
vehicle towing. These laws may
vary by region.
. The towing capacity of the
towing vehicle. Be sure to read
the tow vehicle manufacturer's
recommendations.
. How far the vehicle will be
towed. Some vehicles have
restrictions on how far and how
long they can tow.
. The proper towing equipment.
See your dealer or trailering
professional for additional advice
and equipment
recommendations.
. If the vehicle is ready to be
towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.

Vehicle Care 365
Dinghy TowingCaution
If the vehicle is towed with all four
wheels on the ground, the
drivetrain components could be
damaged. The repairs would not
be covered by the vehicle
warranty. Do not tow the vehicle
with all four wheels on the
ground.
The vehicle was not designed to be
towed with all four wheels on the
ground. The vehicle may be towed
using a platform trailer with all four
wheels off the ground. Some
vehicles may be dolly towed. See
the following information on dolly
towing.
Dolly Towing (All-Wheel-Drive
Vehicles)
All-wheel-drive vehicles cannot be
towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground.
Dolly Towing
(Front-Wheel-Drive Vehicles)
Tow the vehicle with the two rear
wheels on the ground and the front
wheels on a dolly.
To tow the vehicle from the front
with the rear wheels on the ground:1. Put the front wheels on the dolly.
2. Shift the transmission to P (Park). See Shifting Into Park
0 202.
3. Set the parking brake.
4. Secure the vehicle to the dolly.

Service and Maintenance 377
The Tire Rotation and Required
Services are the responsibility of the
vehicle owner. It is recommended to
have your dealer perform these
services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions.
Because of the way people use
vehicles, maintenance needs vary.
There may need to be more
frequent checks and services. The
Additional Required Services -
Normal are for vehicles that:
.Carry passengers and cargo
within recommended limits on
the Tire and Loading Information
label. See Vehicle Load Limits
0 191.
. Are driven on reasonable road
surfaces within legal driving
limits.
. Use the recommended fuel.
See Recommended Fuel (LYX -
1.5L L4 Turbo Engine) 0260 or
Recommended Fuel (LTG - 2.0L
L4 Turbo Engine) 0260. Refer to the information in the
Maintenance Schedule Additional

Mainly driven in heavy city traffic
in hot weather.
. Mainly driven in hilly or
mountainous terrain.
. Frequently towing a trailer.
