Section 2 Features and Controls

Automatic Transmission Operation
Your vehicle is equipped with an automatic transmission
and features an electronic shift position indicator
located within the instrument panel cluster.
There are several different positions for your shift lever.
PARK (P):This position locks your drive wheels. It’s
the best position to use when you start your engine
because your vehicle can’t move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move
CAUTION: (Continued)
CAUTION: (Continued)
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into Park (P) on
page 2-30. If you are pulling a trailer, see
Towing a Trailer on page 4-75.
{CAUTION:
Your vehicle will be free to roll — even if your
shift lever is in PARK (P) — if your transfer
case is in NEUTRAL. So, be sure the transfer
case is in a drive gear — not in NEUTRAL. See
Shifting Into Park (P) on page 2-30.
2-22

REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
see If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-56.
NEUTRAL (N):In this position, your engine doesn’t
connect with the drive wheels. To restart when you’re
already moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
2-23

DRIVE (D):This position is for normal driving. If you
need more power for passing, and you’re:
Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
DRIVE (D) can be used when towing a trailer, carrying
a heavy load, driving on steep hills or for off-road driving.
You may want to shift the transmission to THIRD (3)
or, if necessary, a lower gear selection if the
transmission shifts too often.
THIRD (3):This position is also used for normal driving,
however it offers more power and lower fuel economy
than DRIVE (D).
SECOND (2):This position gives you more power but
lower fuel economy. You can use SECOND (2) on
hills. It can help control your speed as you go down
steep mountain roads, but then you would also want to
use your brakes off and on.If you manually select SECOND (2), the transmission
will drive in second gear. You may use this feature
for reducing the speed of the rear wheels when you are
trying to start your vehicle from a stop on slippery
road surfaces. Once the vehicle is moving, shift into
DRIVE (D).
FIRST (1):This position gives you even more power,
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1) while the vehicle is moving
forward, the transmission won’t shift into rst gear
until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
On cold days, approximately 32°F (0°C) or colder, your
transmission is designed to shift differently until the
engine reaches normal operating temperature. This is
intended to improve heater performance.
2-24

Tow/Haul Mode
Your vehicle is equipped
with a tow/haul mode. The
button is located on the
instrument panel to
the right of the steering
wheel.
You can use this feature to assist when towing or
hauling a heavy load. See “Tow/Haul Mode” under
Towing a Trailer on page 4-75for more information.
All-Wheel Drive
All-wheel drive sends your engine’s driving power to all
four wheels for extra traction. To get the most
satisfaction out of all-wheel drive, you must be familiar
with its operation.
Notice:Driving on pavement in 4HI Lock or
4LO Lock for extended periods may cause
premature wear on your vehicle’s powertrain and
tires. Do not drive in 4HI Lock or 4LO Lock on
pavement for extended periods.
Transfer Case Buttons
The transfer case buttons
are located to the right of
the instrument panel
cluster. Use these switches
to shift into and out of the
different all-wheel drive
modes.
You can choose between four modes:
G(4HI):This setting is used for driving in most
street and highway situations. You can also use this
setting for light or variable off-road conditions.
H(4HI Lock):Use this mode when you need extra
traction in most off-road situations such as sand,
mud, snow or level, rocky trails.
2-25

I(4LO Lock):This mode delivers extra torque to all
four wheels and is used for extreme off-road conditions.
You might choose 4LO Lock if you are driving off-road,
deep sand, mud, or snow and climbing or descending
steep hills.
When in this mode you can also choose to lock the rear
axle for additional traction in extreme off-road situations.
SeeLocking Rear Axle on page 4-11.
Notice:Operating your vehicle in 4LO Lock above
50 mph (80 km/h) for any extended period of time
could cause damage to the transfer case. Do
not operate your vehicle in 4LO Lock above 50 mph
(80 km/h) for extended periods.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. SeeParking Brake on
page 2-29.N (NEUTRAL):Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 4-65orTowing
Your Vehicle on page 4-65for more information.
Indicator lights in the buttons show which mode you are
in. The indicator lights will come on briey when you
turn on the ignition and one will stay on. If the lights do
not come on, you should take your vehicle to your
dealer for service. An indicator light will ash while
shifting the transfer case. It will remain illuminated when
the shift is complete. If for some reason the transfer
case cannot make a requested shift, it will return to the
last chosen setting.
If the SERVICE 4WD message stays on, you should
take your vehicle to your dealer for service. See “Service
4WD message” underDriver Information Center (DIC)
on page 3-44.

{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
{CAUTION:
All-wheel drive vehicles with the transfer case
in NEUTRAL will allow the vehicle to roll, even
if your shift lever is in PARK (P). So, be sure
the transfer case is in a drive gear — not in
NEUTRAL. Always set your parking brake.Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-30.
If you are pulling a trailer, seeTowing a Trailer on
page 4-75.
Mirrors
Automatic Dimming Rearview Mirror
with Compass and Temperature
Display
The automatic dimming mirror will automatically dim to
the proper level to minimize glare from lights behind
you after dark.
The mirror also includes a display in the upper right
corner of the mirror. The compass reading and
the outside temperature will both appear in the display
at the same time. The dual display can be turned
on or off by briey pressing either the TEMP or the
COMP button.
