Headphones
Wireless Headphones
The RSE system might include two sets of
wireless headphones. Each headphone has an
L marked on the left-side, for the left ear and an
R marked on the right-side, for the right ear. The
L and R marks are to show how the headphones
should be worn.
OFF/ON (Power):The wireless headphones have
an OFF/ON power switch located on the
earpiece. To use the headphones, turn the switch
to ON. An indicator light on the earpiece of the
headphones illuminates. If the light does not
illuminate, the batteries might need to be replaced.
See “Battery Replacement” later in this section.
Switch the headphones to OFF when not in use.
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 transmitter
window for more than three minutes. The
transmitter window is located on the bottom edge
of the monitor. If you move too far forward or
step out of the vehicle, the headphones could lose
the audio signal.Channel Selector:The wireless headphones
have a channel selector switch located on the right
earpiece. The channel selector switches between
Channel A and Channel B. Since each monitor
can function as two independent sources through
auxiliary input, it is necessary to transmit audio
signals on separate channels. The driver’s
side monitor is designated as Channel A, and the
passenger’s side as Channel B. The Headphone
channel selector switch must be set to the
correct channel according to the monitor being
viewed. When the head restraint monitor is initially
turned on, the message, “To listen to this
monitor tune your headphones to channel A
(or B)” displays for ve seconds then disappears.
VOL
0(Volume):To adjust the volume
on the wireless headphones, use the volume
control.
Notice:Do not store the headphones in heat
or direct sunlight. This could damage the
headphones and repairs will not be covered by
your warranty. Keep the headphones stored
in a cool, dry place.

Locking Rear Axle
The locking rear axle can give your vehicle
additional traction from the rear wheels when
traveling in off-road situations such as mud, snow,
sand, steep hills and uneven terrain.
The button used to turn
this feature on or off is
located above the
transfer case buttons
to the right of the
steering wheel.
To lock the rear axle, do the following:
1. Place the transfer case in the Four-Wheel-Low
Lock mode. This is the only mode which will
allow the rear axle to lock. SeeFull-Time
Four-Wheel Drive on page 128for more
information regarding the transfer case and
Four-Wheel-Low-Lock mode.
2. Press the button with the vehicle stopped or
moving less than 2 mph (3 km/h).You must wait for the light in the button to stop
ashing and remain illuminated before the
rear axle is locked.
Notice:If you try to lock the rear axle while
your vehicle is stuck and the tires are spinning,
you could damage your vehicle’s drivetrain.
The repairs would not be covered by your
warranty. Always lock the rear axle before
attempting situations and/or navigating terrain
which could possibly cause the vehicle to
become stuck.
The locking rear axle will be disengaged when the
vehicle’s speed is greater than 20 mph (32 km/h), if
the vehicle’s battery is low and/or the transfer case
is shifted out of Four-Wheel-Low-Lock mode.
Notice:If you lock the rear axle while driving
on pavement, you could damage your
vehicle’s drivetrain. The repairs would not be
covered by your warranty. Do not use the
locking rear axle on pavement. If you need
four-wheel drive when traveling on pavement,
use only 4HI.

You can run the engine to keep warm, but be
careful.
{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
your 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.
356

You will need a well-charged battery to restart the
vehicle, and possibly for signaling later on with your
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
In order to free your vehicle when it is stuck,
you will need to spin the wheels, but you do not
want to spin your wheels too fast. The method
known as rocking can help you get out when you
are stuck, but you must use caution.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or others
could be injured. And, the transmission or
other parts of the vehicle can overheat.
That could cause an engine compartment
re or other damage. When you are stuck,
spin the wheels as little as possible. Do not
spin the wheels above 35 mph (55 km/h) as
shown on the speedometer.
Notice:Spinning the wheels can destroy parts
of your vehicle as well as the tires. If you
spin the wheels too fast while shifting
the transmission back and forth, you can
destroy the transmission.
For information about using tire chains on your
vehicle, seeTire Chains on page 465.

Dinghy Towing
Use the following procedure to tow your vehicle:
1. Shift the transmission to PARK (P).
2. Turn the engine off, but leave the ignition in
ACCESSORY.
3. Firmly set the parking brake.
4. Securely attach the vehicle being towed to the
tow vehicle.
{CAUTION:
Shifting a full-time four-wheel-drive
vehicle’s transfer case into NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or others
could be injured. Make sure the parking
brake is rmly set before you shift the
transfer case to NEUTRAL.
5. Shift the transfer case to NEUTRAL (N).
SeeFull-Time Four-Wheel Drive on
page 128for the proper procedure to select
the NEUTRAL position for your vehicle.6. Release the parking brake only after the
vehicle being towed is rmly attached to
the towing vehicle. You can use your vehicle’s
front mounted receiver with the proper
accessories to tow it. See “Front Mounted
Receiver” underIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 357.
7. Turn the ignition to ACCESSORY.
8. Disconnect the battery if you are going to tow
for long distances or long periods of time.
When towing your vehicle for extended periods of
time, start your vehicle as often as possible to
prevent battery drain. This should only be
done when the tow vehicle is parked.
Dolly Towing
Your vehicle cannot be dolly towed. If you must
tow your vehicle behind another, use the
dinghy towing procedure listed previously.
Notice:Dolly towing your vehicle will damage
drivetrain components. Do not dolly tow
your vehicle.
