Magnetic Ride Control™
The vehicle may have the MagneRide control system.
MagneRide constantly checks speed, wheel position,
lift/dive and steering of the vehicle. The damping force
for each shock absorber and adjustment level is chosen
for the best ride and handling.
MagneRide also works with the tow/haul switch that,
when engaged, will provide more firmness from the
shock absorbers. This added control gives better ride
and handling when carrying heavy loads or towing a
trailer. SeeTow/Haul Mode
on page 3‑39for more
information.
Road Sensing Suspension
The Road Sensing Suspension (RSS) feature provides
superior vehicle ride and handling under a variety of
passenger and loading conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed, wheel
to body position, lift/dive and steering position of the
vehicle. The controller then sends signals to each shock
absorber to independently adjust the damping level to
provide the optimum vehicle ride. RSS also interacts with the tow/haul mode that, when
engaged, will provide additional control of the shock
absorbers. This additional control results in better ride
and handling characteristics when the vehicle is loaded
or towing a trailer. See
“Tow/Haul Mode”underTowing a
Trailer on page 6‑42.
Locking Rear Axle
Vehicles with a locking rear axle can give more traction
on snow, mud, ice, sand or gravel. It works like a
standard axle most of the time, but when traction is low,
this feature will allow the rear wheel with the most
traction to move the vehicle.
All-Wheel Drive (AWD) System
With this feature, engine power is sent to all four wheels
at all times. This is like four-wheel drive, but there is no
separate lever or switch to engage or disengage the
front axle. It is fully automatic, and adjusts itself as
needed for road conditions.

Driving in Water
{WARNING:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown. If it is
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Do not drive
through rushing water.
Heavy rain can mean flash flooding, and flood waters
demand extreme caution.
Find out how deep the water is before driving through
it. Do not try it if it is deep enough to cover the wheel
hubs, axles, or exhaust pipe —you probably will not get
through. Deep water can damage the axle and other
vehicle parts.
If the water is not too deep, drive slowly through it. At
faster speeds, water splashes on the ignition system
and the vehicle can stall. Stalling can also occur if you
get the tailpipe under water. If the tailpipe is under
water, you will never be able to start the engine.
When going through water, remember that when the
brakes get wet, it might take longer to stop. See Driving
in Rain and on Wet Roads on page 6‑25.
After Off-Road Driving
Remove any brush or debris that has collected on
the underbody, chassis, or under the hood. These
accumulations can be a fire hazard.
After operation in mud or sand, have the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the body structure,
steering, suspension, wheels, tires, and exhaust system
for damage and check the fuel lines and cooling system
for any leakage.
The vehicle requires more frequent service due to
off-road use. Refer to the Maintenance Schedule for
additional information.
Driving at Night
Night driving is more dangerous than day driving
because some drivers are likely to be impaired —by
alcohol or drugs, with night vision problems, or
by fatigue.
Night driving tips include:
.Drive defensively.
.Do not drink and drive.
.Reduce headlamp glare by adjusting the inside
rearview mirror.
6-24
{WARNING:
Do not load the vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do, parts
on the vehicle can break, and it can change
the way the vehicle handles. These could
cause you to lose control and crash.
Also, overloading can shorten the life of
the vehicle.
The vehicle warranty does not cover parts or
components that fail because of overloading.
The label will help you decide how much cargo
and installed equipment the truck can carry.
Using heavier suspension components to get
added durability might not change your weight
ratings. Ask your dealer/retailer to help you load
the vehicle the right way. If you put things inside the vehicle
—like
suitcases, tools, packages, or anything
else —they go as fast as the vehicle goes. If you
have to stop or turn quickly, or if there is a crash,
they will keep going.
{WARNING:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn,
or in a crash.
.Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
.Never stack heavier things, like
suitcases, inside the vehicle so that some
of them are above the tops of the seats.
.Do not leave an unsecured child restraint
in your vehicle.
.When you carry something inside the
vehicle, secure it whenever you can.
.Do not leave a seat folded down unless
you need to.
6-37
There is also important loading information for
off-road driving in this manual. See“Loading Your
Vehicle for Off-Road Driving” underOff-Road
Driving
on page 6‑13.
Add-On Equipment
When you carry removable items, you may need
to put a limit on how many people you can carry
inside the vehicle. Be sure to weigh the vehicle
before you buy and install the new equipment.
Notice :Overloading the vehicle may cause
damage. Repairs would not be covered by the
vehicle warranty. Do not overload the vehicle.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.
The Cargo Weight Rating (CWR) is the maximum
weight of the load the vehicle can carry. It does
not include the weight of the people inside. But
you can figure about 150 lbs (68 kg) for each seat.
The total cargo load must not be more than the
vehicle's CWR.
Automatic Level Control
The automatic level control rear suspension
comes as a part of the Road Sensing Suspension.
See Road Sensing Suspension
on page 6‑9.
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 air compressor connected
to the rear shocks will raise or lower the rear of
the vehicle to maintain proper vehicle height.
The system is activated when the ignition key is
turned to ON/RUN and will automatically adjust
vehicle height thereafter. The system may exhaust
(lower vehicle height) for up to 10 minutes after
the ignition key has been turned to OFF/LOCK.
You may hear the air compressor operating when
the height is being adjusted.
6-38
Level Control
Automatic Level Control
The automatic level control rear suspension is available
on light‐duty vehicles and comes as a part of the
Autoride
®suspension, if equipped.
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 air compressor connected to the rear
shocks will raise or lower the rear of the vehicle to
maintain proper vehicle height. The system is activated
when the ignition key is turned to ON/RUN and will
automatically adjust vehicle height thereafter. The
system may exhaust (lower vehicle height) for up to
ten minutes after the ignition key has been turned off.
You may hear the air compressor operating when the
height is being adjusted.
If a weight‐distributing hitch is being used, it is
recommended to allow the shocks to inflate, thereby
leveling the vehicle prior to adjusting the hitch.
Autoride®
With this feature, improved vehicle ride and handling is
provided under a variety of passenger and loading
conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed, wheel
to body position, lift/dive and steering position of the
vehicle. The controller then sends signals to each shock
absorber to independently adjust the damping level to
provide the optimum vehicle ride.
Autoride also interacts with the tow/haul mode that,
when activated, will provide additional control of the
shock absorbers. This additional control results in better
ride and handling characteristics when the vehicle is
loaded or towing a trailer. See “Tow/Haul Mode”under
Towing a Trailer
on page 6‑42for more information.
6-41
Notice: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.
See Changing a Flat Tire
on page 7‑79for more
information.
Used Replacement Wheels
{WARNING:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how far
it has 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
{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, or other
vehicle parts. The area damaged by the tire
chains could cause you to lose control of the
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 the
vehicle and tire size combination and road
conditions. Follow that manufacturer's
instructions. To help avoid damage to the vehicle,
drive slowly, re‐adjust or remove the device if it is
contacting the vehicle, and do not spin the
wheels. If you do find traction devices that will fit,
install them on the rear tires.
