various multi‐media. The wireless
headphones have a power button,
channel 1/2 switch, and a volume
control. Turn the headphones off
when not in use.
Push the power button to turn on
the headphones. A light on the
headphones comes on. If the light
does not come on, check the
batteries. Intermittent sound or static
can also indicate weak batteries.
See“Battery Replacement” later in
this section for more information.
Infrared transmitters are on the top
of the left seatback video screen.
The headphones shut off
automatically to save the battery
power if the RSE system is shut off
or if the headphones are out of
range of the transmitters for more
than three minutes. Moving too far
forward or stepping out of the
vehicle can cause the headphones
to lose the signal or have static. To adjust the volume on the
headphones, use the volume
control.
For optimal audio performance, the
headphones must be worn correctly.
Headphones should be worn with
the headband over the top of the
head for best audio reception. The
symbol L (Left) appears on the
outside bottom edge of the ear cup
and should be positioned on the left
ear. The symbol R (Right) appears
on the outside bottom edge of the
ear cup and should be positioned on
the right ear.
Notice:
Do not store the
headphones in heat or direct
sunlight. This could damage the
headphones and repairs will not
be covered by the warranty.
Storage in extreme cold can
weaken the batteries. Keep the
headphones stored in a cool, dry
place. If the foam ear pads attached to the
headphones become worn or
damaged, the pads can be replaced
separately from the headphone set.
To purchase replacement ear pads,
call 1‐888‐293‐3332, then prompt
zero (0), or contact your dealer.

7-26 Infotainment System
Audio Output
Audio from the DVD player or
auxiliary inputs can be heard
through the following:
.Wireless Headphones
.Vehicle Speakers
The RSE system transmits the
audio signal to the wireless
headphones if an audio signal is
available. See “Headphones” earlier
in this section for more information.
The front seat passengers are able
to listen to playback from the A/V
jacks through the vehicle speakers
by selecting Rear A/V as the source
on the radio.
Video Screens
The video screens are located in the
back of the driver and front
passenger seats.
To use the video screen:
1. Push the release button located on the seatback console.
2. Move the screen to the desired viewing position.
Push the video screen down into its
locked position when it is not in use.
The screen turns off automatically.
Only the left RSE seatback console
contains the infrared transmitters for
the wireless headphones. They may
be visible as eight illuminated LEDs.
These LEDs are not on the right
video screen. Both seatback consoles contain an infrared
receiver for the remote control. They
are located at the top of each
console.
Notice:
Avoid directly touching
the video screen, as damage may
occur. See “Cleaning the Video
Screens” later in this section for
more information.
Video Screen Input Jack
Each video screen is equipped with
a video input jack to allow video
cables to be connected from an
auxiliary device such as a
camcorder or a video game system.
This signal will override any video
provided by the RSE system; either
the DVD or auxiliary A/V jack
source. The RSE system must be
on for this input to operate.

sight could also affect the function
of the remote control. If a CD, DVD, or MP3 disc is in the
Radio DVD slot, the remote control
Obutton can be used to turn on the
video screen display and start the
disc. The infotainment system can
also turn on the video screen
display. See the separate navigation
manual for more information.
Notice: Storing the remote
control in a hot area or in direct

Driving and Operating 9-15
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See
Traction
Control System (TCS) on
page 9‑35.
{WARNING
If the 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 fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph).
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑65.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a forward
gear, spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears.
Release the accelerator pedal while
shifting, and press lightly on the
accelerator pedal when the
transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. If the vehicle
does need to be towed out, see
Towing the Vehicle on page 10‑79.

Driving and Operating 9-49
When the vehicle crosses a
detected lane marking, the LDW
indicator will flash and three beeps
will sound. LDW will not warn if the
turn signal is on or if a sharp
maneuver is made.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press the
LANE DEPART control on the
steering wheel. The control indicator
will light when LDW is on.When the vehicle is started, the
LDW indicator on the instrument
panel will come on briefly.
LDW operates at speeds of 56 km
(35 mph) or greater. If LDW is on,
the LDW indicator will appear green
if the system detects a left or right
lane marking. This indicator will
change to amber, flash, and three
beeps will sound if the vehicle
crosses a detected lane marking
without using the turn signal.

Driving and Operating 9-59
Backing Up
Hold the bottom of the steering
wheel with one hand. 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.
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument panel flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well. The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
will boil at a lower temperature than
at normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle may show signs
similar to engine overheating. To
avoid this, let the engine run while
parked, preferably on level ground,
with the transmission in P (Park) for
a few minutes before turning the
engine off. If the overheat warning
comes on, see
Engine Overheating
on page 10‑20.
