Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that
helps prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 4-17. 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 the 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
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to apply
the brakes if that vehicle suddenly
slows or stops. Always leave
enough room up ahead to stop,
even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and
let antilock work. The antilock pump
or motor might be heard operating,
and the brake pedal might be
felt to pulsate, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help more
than even the very best braking.

StabiliTrak System
The vehicle has the StabiliTrak
system which combines antilock
brake, traction and stability control
systems. This system automatically
controls the brakes and engine to
help prevent the vehicle from
skidding when cornering on a
slippery road surface or turning
the steering wheel abruptly.
This system activates when the
vehicle speed reaches or exceeds
15 km/h (9 mph), and deactivates
when the vehicle speed reduces to
below 15 km/h (9 mph).
A sound may be heard in the engine
compartment for a few seconds
when the engine is started or just
after the vehicle begins to move.
This means that the system is in
the self-check mode, but does not
indicate a problem.If the vehicle is going to skid during
driving, the traction control system
warning light flashes and an alarm
sounds intermittently. Adjust your
driving accordingly.
To turn off both the traction control
system and StabiliTrak, press and
hold

system or StabiliTrak.
Driving and Operating 8-35

Cruise Control
For vehicles with cruise control, the
lever is located on the right side
of the steering wheel.Cruise control, lets a speed of
25 mph (40 km/h) or more be
maintained without keeping your foot
on the accelerator. Cruise control
does not work at speeds below
25 mph (40 km/h).
{CAUTION
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.Setting Cruise Control
{CAUTION
If you leave your cruise control on
when you are not using cruise,
you might hit a button and go into
cruise when you do not want to.
You could be startled and even
lose control. Keep the cruise
control switch off until you want to
use cruise control.
1. Press the ON-OFF button at the end of the lever. The CRUISE
light on the instrument panel
cluster comes on. See Cruise
Control Light on page 4-21 .
2. Get to the desired speed.
3. Move the lever down to −SET
and release it.
4. Take your foot off the accelerator pedal.
8-36 Driving and Operating

•Vehicles with an automatic
transmission can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts too
often under heavy loads and/or
hilly conditions. For vehicles with
a manual transmission, it is better
not to use the highest gear.
•Use the Sport Shift mode and the
cruise control when towing.
•Obey speed limit restrictions
when towing a trailer. Do not drive
faster than the maximum posted
speed for trailers, or no more than
90 km/h (55 mph), to save wear
on the vehicle’s parts.
Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Get to know
the rig before setting out for the open
road. Get acquainted with the feel of
handling and braking with the added
weight of the trailer. And always keep
in mind that the vehicle you are
driving is now longer and not as
responsive as the vehicle is by itself.Before starting, check all trailer
hitch parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirror adjustments. If the
trailer has electric brakes, start the
vehicle and trailer moving and then
apply the trailer brake controller by
hand to be sure the brakes are
working. This checks the electrical
connection at the same time.
During the trip, check occasionally
to be sure that the load is secure,
and that the lamps and any
trailer brakes are still working.
Towing with StabiliTrak
When towing, the sound of the
StabiliTrak modulator might
be heard. StabiliTrak is reacting to
the vehicle movement caused
by the trailer, which mainly occurs
during cornering. This is normal
when towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations that
require heavy braking and sudden
turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the lane.
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move the
trailer to the left, move that hand to
the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and, if
possible, have someone guide you.

If No Steam Is Coming From
Your Engine
If an engine overheat warning is
displayed but steam is not heard or
seen escaping, the problem may
not be too serious. Sometimes
the engine can get a little too
hot when the vehicle:
•Climbs a long hill on a hot day.
•Stops after high-speed driving.
•Idles for long periods in traffic.
•Tows a trailer.
If the overheat warning is displayed
with no sign of steam, try this for
a minute or so:
1. In heavy traffic, let the engine idle in N (Neutral) while stopped. If it
is safe to do so, pull off the road,
shift to P (Park) or N (Neutral)
and let the engine idle.
2. Turn on the heater to full hot at the highest fan speed and open
the windows as necessary. If the overheat warning is no longer
displayed, the vehicle can be driven.
Just to be safe, drive slower for about
10 minutes. If the warning does not
come back on, continue to drive.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is still no sign of steam, idle
the engine for three minutes while
the vehicle is parked. If the warning
is still displayed, turn off the engine
and get everyone out of the vehicle
until it cools down.
You may decide not to lift the hood
but to get service help right away.
Power Steering Fluid
The vehicle has electronic power
steering and does not use power
steering fluid. If you suspect a
problem, see your dealer/retailer.
Washer Fluid
What to Use
When you need windshield
washer fluid, be sure to read
the manufacturer’s instructions
before use. If you will be operating
your vehicle in an area where the
temperature may fall below freezing,
use a fluid that has sufficient
protection against freezing.
