Magnetic Ride Control
Magnetic Ride Control automatically adjusts the ride of
your vehicle. Automatic ride control is achieved
through a computer used to control and monitor the
suspension system. The controller receives input from
various sensors to determine the proper system
response. If the controller detects a problem within the
system, the DIC will display a SERVICE SUSPENSION
SYS message. See
DIC Warnings and Messages
on page 3-56for more information. See your dealer for
service.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Magnetic Speed Variable Assist
Steering
Your vehicle may be equipped with a steering system
that continuously adjusts the effort you feel when
steering at all vehicle speeds. It provides ease when
parking, yet a ®rm, solid feel at highway speeds.
Steering Tips
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº accidents mentioned on
the news happen on curves. Here's why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there's no traction, inertia
will keep the vehicle going in the same direction. If
you've ever tried to steer a vehicle on wet ice, you'll
understand this.
4-11

The vehicle should be properly prepared as follows:
·The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other ¯at
surface.
·The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other ¯at surface.
·The vehicle should be placed so it is perpendicular
to the wall or other ¯at surface.
·The vehicle should not have any snow, ice or mud
attached to it.
·The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
·The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs (75 kg) on
the driver's seat.
·Tires should be properly in¯ated.
·Start the vehicle and rock it to level the suspension.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.The headlamp aiming devices are under the hood near
the headlamps.
If you believe your headlamps need horizontal (left/right)
adjustment, follow the horizontal aiming procedure. If
you believe your headlamps need only vertical
(up/down) adjustment, follow only the vertical aiming
procedure.
Adjustment screws can be turned with an E8 Torx
ž
socket or T15 Torx screwdriver.

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.
Tire Chains
{CAUTION:
If your vehicle has P235/55R17 size tires, don't
use tire chains, there's 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, readjust or remove the
device if it's contacting your vehicle, and don't
spin your wheels.
If you do ®nd traction devices that will ®t,
install them on the front tires.
