volume level remains in memory for
later calls. To prevent missed calls, a
minimum volume level is used if the
volume is turned down too low.

Headphones should be stored in the
front oor console and not in the
front seat back pocket. Headphone
damage can occur when the
second row seats are folded
forward.
Battery Replacement
To change the batteries on the
headphones:
1. Turn the screw to loosen the
battery door located on the
left side of the headphones.
Slide the battery door open.
2. Replace the two batteries in the
compartment. Make sure that
they are installed correctly, using
the diagram on the inside of
the battery compartment.
3. Replace the battery door and
tighten the door screw.
If the headphones are to be stored
for a long period of time, remove
the batteries and keep them
in a cool, dry place.Audio/Video (A/V) Jacks
The A/V jacks, located on the rear
of the oor console, allow audio
or video signals to be connected
from an auxiliary device such
as a camcorder or a video game
unit to the RSE system. Adapter
connectors or cables (not supplied)
might be required to connect the
auxiliary device to the A/V jacks.
Refer to the manufacturer’s
instructions for proper usage.The A/V jacks are color coded to
match typical home entertainment
system equipment. The yellow
jack (A) is for the video input.
The white jack (B) is for the left
audio input. The red jack (C) is for
the right audio input.
Power for auxiliary devices is not
supplied by the radio system.
To use the auxiliary inputs of the
RSE system, connect an external
auxiliary device to the color-coded
A/V jacks and turn both the auxiliary
device and the video screen
power on. If the video screen is in
the DVD player mode, pressing
the AUX (auxiliary) button on
the remote control, switches the
video screen from the DVD player
mode to the auxiliary device.
The radio can listen to the audio of
the connected auxiliary device by
sourcing to auxiliary. SeeRadio(s)
on page 3-74for more information.

And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry, or icy;
tire tread; the condition of the brakes;
the weight of the vehicle; and the
amount of brake force applied.
Avoid needless heavy braking. Some
people drive in spurts — heavy
acceleration followed by heavy
braking — rather than keeping pace
with traffic. This is a mistake. The
brakes might not have time to cool
between hard stops. The brakes will
wear out much faster with a lot of
heavy braking. Keeping pace with
the traffic and allowing realistic
following distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to
push down. If the engine stops,there will still be some power brake
assist but it will be used when
the brake is applied. 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 vehicle
performance. SeeAccessories and
Modifications on page 5-3.
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that will
help 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. See
Antilock Brake System (ABS)
Warning Light on page 3-39.
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.
4-4 Driving Your Vehicle

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 rmly and
let antilock work. The antilock pump
or motor operating might be
heard 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.
Brake Assist
This vehicle has a Brake Assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsations or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal
as the driving situation dictates.The Brake Assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly decreased.
StabiliTrak®System
The vehicle has the StabiliTrak
system 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 the vehicle and
begin to drive away, the system
performs several diagnostic checks
to ensure there are no problems. The
system may be heard or felt while it
is working. This is normal and does
not mean there is a problem with the
vehicle. The system should initialize
before the vehicle reaches 20 mph
(32 km/h). In some cases, it may take
approximately two miles of driving
before the system initializes.

Towing a Trailer
{CAUTION
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly.
For example, if the trailer is too
heavy, the brakes may not work
well — or even at all. The driver
and passengers could be
seriously injured. The vehicle may
also be damaged; the resulting
repairs would not be covered by
the vehicle warranty. Pull a trailer
only if all the steps in this section
have been followed. Ask your
dealer/retailer for advice and
information about towing a trailer
with the vehicle.
To identify the trailering capacity of
the vehicle, read the information
in “Weight of the Trailer” that
appears later in this section.Trailering is different than just
driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
durability and fuel economy.
Successful, safe trailering takes
correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering
tips and safety rules. Many of these
are important for the safety of the
driver and the passengers. So
please read this section carefully
before pulling a trailer.
Load-pulling components such as
the engine, transmission, rear
axle, wheel assemblies and tires are
forced to work harder against the
drag of the added weight. The
engine is required to operate
at relatively higher speeds and
under greater loads, generating
extra heat. What’s more, the trailer
adds considerably to wind
resistance, increasing the pulling
requirements.
Pulling A Trailer
Here are some important points:
There are many different
laws, including speed limit
restrictions, having to do with
trailering. Make sure the rig will
be legal, not only where you
live but also where you will be
driving. A good source for
this information can be state or
provincial police.
Consider using a sway control.
See “Hitches” later in this section.
Do not tow a trailer at all during
the rst 500 miles (800 km) the
new vehicle is driven. The engine,
axle or other parts could be
damaged.
Then, during the rst 500 miles
(800 km) that a trailer is towed, do
not drive over 50 mph (80 km/h)
and do not make starts at full
throttle. This helps the engine and
other parts of the vehicle wear in
at the heavier loads.
