Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to any
of the audio sources: radio, cassette tapes, or CDs,
depending on your vehicles options. However, the rear
seat passengers can only control the music sources
that the front seat passengers are not listening to. For
example, rear seat passengers may listen to a cassette
tape through headphones while the driver listens to
the radio through the front speakers. The rear seat
passengers have control of the volume for each set of
headphones. The front seat audio controls always
override the RSA controls.

The following functions are controlled by the RSA
system buttons:

audio system on or off. The rear speakers will be muted
when the power is turned on unless your vehicle is

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 4LO Lock mode. This
is the only mode which will allow the rear axle to
lock. SeeAll-Wheel Drive on page 2-25for
more information regarding the transfer case and
4LO 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 4LO 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.
