Magnetic Ride Control
If equipped, the Magnetic Ride Control
monitors the suspension system.
Based on road conditions, steering
wheel angle, and vehicle speed, the
system automatically adjusts to
provide the best handling while
providing a smooth ride. The Tour and
Sport Modes will feel similar on a
smooth road.
Tour : Use for normal city and
highway driving. This setting provides
a smooth, soft ride.
Sport : Use where road conditions or
personal preference demand more
control. This setting provides more
“feel,” or response to road conditions.
The vehicle is normally in Tour Mode.
Sport Mode is engaged when the shift
lever is placed in M (Manual Mode). When the shift lever is placed in D
(Drive) the system will revert back to
Tour Mode.
The Driver Information Center (DIC)
may briefly display a message on
vehicle startup or when a new mode is
selected.Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow, mud,
ice, sand or gravel. When traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. The limited-slip rear axle
also gives the driver enhanced control
when cornering hard or completing a
maneuver, such as a lane change.
Automatic Level Control
The automatic level control rear
suspension is available on some
vehicles.
This type of level control is fully
automatic and will provide a better
leveled riding position as well as
better handling under a variety of
passenger and loading conditions. An

286 VEHICLE CARE
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
can be dangerous. It could affect
the braking and handling of the
vehicle. Tires can lose air, and
cause loss of control, causing a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
Caution
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.
Professional vehicle wheels have a
unique offset and bolt hole diameter.
Professional vehicle wheels have six wheel nuts. Non-professional vehicle
wheels have five wheel nuts. See
Tire
Changing 0295.
Used Replacement Wheels
{Warning
Replacing a wheel with a used one
is dangerous. How it has been used
or how far it has been driven may
be unknown. It could fail suddenly
and cause a crash. When replacing
wheels, use a new GM original
equipment wheel.
Tire Chains
{Warning
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,
(Continued)
Warning (Continued)
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 it contacts the vehicle. Do
not spin the wheels. If traction
devices are used, install them on
the front tires.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires are
maintained properly. See Tires0267.
If air goes out of a tire, it is much
more likely to leak out slowly. But if
there is ever a blowout, here are a few
tips about what to expect and what
to do:

304 VEHICLE CARE
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to suspension
components. Use the proper straps
around the tires to secure the
vehicle.
Have the vehicle towed on a wheel lift
tow truck or flatbed car carrier. If a
wheel lift tow truck is used, the drive
wheels cannot contact the road while
the vehicle is being towed. A wheel
dolly must be used to lift all drive
wheels off the ground.
Front Attachment Points
The vehicle is equipped with specific
attachment points to be used by the
towing provider. These holes may be
used to pull the vehicle from a flat
road surface onto the flat bed tow
truck.
Consult your dealer or a professional
towing service if the disabled vehicle
must be towed.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle such as 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:
. What is the towing capacity of the
towing vehicle? Be sure to read the
tow vehicle manufacturer's
recommendations.
. What is the distance that will be
traveled? Some vehicles have
restrictions on how far and how
long they can tow.

310 VEHICLE CARE
Caution (Continued)
that have been sprayed with
magnesium, calcium, or sodium
chloride. These chlorides are used
on roads for conditions such as ice
and dust. Always wash the chrome
with soap and water after exposure.
Caution
To avoid surface damage, do not
use strong soaps, chemicals,
abrasive polishes, cleaners, brushes,
or cleaners that contain acid on
aluminum or chrome-plated wheels.
Use only approved cleaners. Also,
never drive a vehicle with
aluminum or chrome-plated wheels
through an automatic car wash that
uses silicone carbide tire cleaning
brushes. Damage could occur and
the repairs would not be covered by
the vehicle warranty.
Brake System
Visually inspect brake lines and hoses
for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake
pads for wear and rotors for surface
condition. Inspect drum brake linings/
shoes for wear or cracks. Inspect all
other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering, suspension,
and chassis components for damaged,
loose, or missing parts or signs of
wear at least once a year.
Inspect power steering for proper
attachment, connections, binding,
leaks, cracks, chafing, etc.
Visually check constant velocity joint
boots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood
hinges, liftgate hinges, and the steel
fuel door hinges, unless the
components are plastic. Applying
silicone grease on weatherstrips with aclean cloth will make them last
longer, seal better, and not stick or
squeak.
Underbody Maintenance
At least twice a year, spring and fall,
use plain water to flush any corrosive
materials from the underbody. Take
care to thoroughly clean any areas
where mud and other debris can
collect.
Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate
the fluid. Contaminated fluid will
decrease the life of the transfer case
and/or axles and should be replaced.
Sheet Metal Damage
If the vehicle is damaged and requires
sheet metal repair or replacement,
make sure the body repair shop
applies anti-corrosion material to
parts repaired or replaced to restore
corrosion protection.
