If your vehicle’s engine ever stops
while you are driving, brake normally
but do not pump the brakes. If you
do, the pedal could get harder to
push down. If the engine stops, you
will still have some power brake
assist. But you will use it when you
brake. Once the power assist is used
up, it can take longer to stop and the
brake pedal will be harder to push.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.Antilock Brake
System (ABS)
Your vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that
will help prevent a braking skid.
When you start the engine and
begin to drive away, ABS will check
itself. You might hear a momentary
motor or clicking noise while this
test is going on, and you might even
notice that the brake pedal moves a
little. This is normal.
If there is a problem with ABS,
this warning light will stay on.
SeeAntilock Brake System (ABS)
Warning Light on page 4-18.Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
You slam on the brakes and
continue braking. Here is what
happens with ABS:
A computer senses that wheels
are slowing down. If one of
the wheels is about to stop rolling,
the computer will separately
work the brakes at each wheel.
ABS can change the brake
pressure faster than any driver could.
The computer is programmed to
make the most of available tire and
road conditions. This can help you
steer around the obstacle while
braking hard.
As you brake, the computer keeps
receiving updates on wheel speed
and controls braking pressure
accordingly.
8-18 Driving and Operating
ProCarManuals.com

Remember: ABS does not change
the time you need to get your foot
up to the brake pedal or always
decrease stopping distance. If you
get too close to the vehicle in front of
you, you will not have time to apply
the brakes if that vehicle suddenly
slows or stops. Always leave enough
room up ahead to stop, even though
you have ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down rmly and
let antilock work for you. You might
hear the antilock pump or motor
operate, and feel the brake
pedal pulsate, but this is normal.
Braking in Emergencies
With ABS, you can steer and
brake at the same time. In many
emergencies, steering can help
you more than even the very best
braking.
StabiliTrak®System
Your vehicle may have StabiliTrak
which combines antilock brake,
traction and stability control systems
and helps the driver maintain
directional control of the vehicle
in most driving conditions.
When you rst start your vehicle and
begin to drive away, the system
performs several diagnostic checks
to ensure there are no problems.
You may hear or feel the system
working. This is normal and does not
mean there is a problem with your
vehicle. The system should initialize
before the vehicle reaches 20 mph
(32 km/h).
The system monitors vehicle
movements, and helps the driver
maintain control of the vehicle in
most driving situations. When the
vehicle’s stability is affected the
engine output is reduced, and the
brakes are applied to individual
wheels.When you turn the ignition on,
this light on the instrument panel
cluster will come on for a few
seconds, then go out when the
system is ready.
You may also feel or hear the
system working; this is normal.
StabiliTrak is automatically enabled
whenever you start your vehicle.
To assist the driver with vehicle
directional control, especially in
slippery road conditions, you should
always leave the system on. But, you
can turn it off if you ever need to.
Driving and Operating 8-19
ProCarManuals.com

It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if your vehicle
is stuck in sand, mud, ice or snow,
and you want to “rock” your vehicle
to attempt to free it. It may also be
necessary to turn off the system
when driving in extreme off-road
conditions where high wheel spin
is required. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow
on page 8-29.
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system.
The light on the instrument panel
cluster will be on solid to warn
the driver that StabiliTrak is disabled
and requires service. If the problem
does not clear after restarting
the vehicle, you should see your
dealer/retailer for service.The
gswitch is located on the
instrument panel below the Driver
Information Center (DIC).
To turn off StabiliTrak, press and
hold the
gswitch until the light in the
switch illuminates.
To turn StabiliTrak on again, press
the
gswitch again or restart the
vehicle.
A light in the switch should come
on briey when the ignition key
is turned to ON/RUN as a check
to let you know that the light
is working.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3for
more information.
Steering
If the engine stalls while you
are driving, the power steering assist
system should continue to operate
until you are able to stop the
vehicle. If you lose power steering
assist because the power steering
system is not functioning, you
can steer, but it will take more effort.
If you turn the steering wheel in
either direction several times until it
stops, or hold the steering wheel in
the stopped position for an extended
amount of time, you may notice a
reduced amount of power steering
assist. The normal amount of power
steering assist should return shortly
after a few normal steering
movements.
The power steering system does not
require regular maintenance. If you
suspect steering system problems
and/or the Service Vehicle Soon light
comes on, contact your dealer/
retailer for service repairs.

{CAUTION
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (carbon
monoxide) gas to get inside.
CO could overcome you and
kill you. You cannot see it or
smell it, so you might not know
it is in your vehicle. Clear away
snow from around the base of
your vehicle, especially any
that is blocking the exhaust
pipe. And check around again
from time to time to be sure
snow does not collect there.
Open a window just a little on
the side of the vehicle that is
away from the wind. This will
help keep CO out.Run your engine only as long as you
must. This saves fuel. When you run
the engine, make it go a little faster
than just idle. That is, push the
accelerator slightly. This uses less
fuel for the heat that you get and it
keeps the battery charged. You will
need a well-charged battery to
restart the vehicle, and possibly
for signaling later on with the
headlamps. Let the heater run
for a while.
Then, shut the engine off and close
the window almost all the way to
preserve the heat. Start the engine
again and repeat this only when
you feel really uncomfortable from
the cold. But do it as little as
possible. Preserve the fuel as long
as you can. To help keep warm,
you can get out of the vehicle and
do some fairly vigorous exercises
every half hour or so until help
comes.
If Your Vehicle is
Stuck in Sand, Mud, Ice,
or Snow
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It
Out on page 8-30.
{CAUTION
If you let your vehicle’s tires
spin at high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment re or
other damage. Spin the wheels
as little as possible and avoid
going above 35 mph (55 km/h)
as shown on the speedometer.

chains on the vehicle, seeTire
Chains on page 9-59.

the engine oil level right away.
SeeLow Oil Level Light on
page 4-23. You should check the
engine oil level regularly; this is just
a reminder.
Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on page 9-6
for the location of the engine oil
dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If you do not
do this, the oil dipstick might not
show the actual level.
2. Pull the dipstick and clean it with
a paper towel or cloth, then push
it back in all the way. Remove it
again, keeping the tip down
and check the level.
