Guarding Against Exhaust Fumes
WARNING
If you smell exhaust fumes inside your
vehicle, have your vehicle checked by
your authorized dealer immediately. Do not
drive your vehicle if you smell exhaust fumes.
Carbon monoxide is present in exhaust
fumes. Take precautions to avoid its
dangerous effects. Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods, we
recommend that you do one of the following:
•
Open the windows at least 1 in (3 cm).
• Set your climate control to outside air. ENGINE BLOCK HEATER
(If Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury. Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. Do not fully close the hood, or allow it
to drop under its own weight when
using the engine block heater. This could
damage the power cable and may cause an
electrical short resulting in fire, injury and
property damage. Note:
The heater is most effective when
outdoor temperatures are below 0°F (-18°C).
The heater acts as a starting aid by warming
the engine coolant. This allows the climate
control system to respond quickly. The
equipment includes a heater element
(installed in the engine block) and a wire
harness. You can connect the system to a
grounded 120-volt AC electrical source. We recommend that you do the following for
a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by Underwriter’ s
Laboratory (UL) or Canadian Standards
Association (CSA). This extension cord
must be suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord plug
connections are free and clear of water.
This could cause an electric shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• Make sure the heater, heater cord and
extension cord are firmly connected.

•
Check for heat anywhere in the electrical
hookup once the system has been
operating for approximately 30 minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is checked
for proper operation before winter.
Using the Engine Block Heater
Make sure the receptacle terminals are clean
and dry prior to use. Clean them with a dry
cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours of
energy per hour of use. The system does not
have a thermostat. It achieves maximum
temperature after approximately three hours
of operation. Using the heater longer than
three hours does not improve system
performance and unnecessarily uses
electricity.

1. Fully press down the brake pedal.
2.
Move the gearshift lever into the desired
gear.
3. Come to a complete stop.
4. Move the gearshift lever and securely latch it in park (P).
Park (P)
This position locks the transmission and
prevents the rear wheels from turning. Reverse (R)
With the gearshift lever in reverse (R), your
vehicle will move backward. Always come
to a complete stop before shifting into and
out of reverse (R).
Neutral (N)
With the gearshift lever in neutral (N), your
vehicle can be started and is free to roll. Hold
the brake pedal down while in this position.

Understanding your SelectShift
Automatic
™ Transmission (If Equipped)
Your vehicle is equipped with a SelectShift
Automatic transmission gearshift lever. The
SelectShift Automatic transmission gives you
the ability to change gears up or down
(without a clutch) as desired.
In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift will still automatically make
some downshifts if it has determined that
you have not downshifted in time. Although
SelectShift will make some downshifts for
you, it will still allow you to downshift at any
time as long as the SelectShift determines
that damage will not be caused to the engine
from over-revving.
SelectShift will not automatically upshift, even
if the engine is approaching the RPM limit. It
must be shifted manually by pressing the +
button. Note:
Engine damage may occur if you
maintain excessive engine revving without
shifting.
The SelectShift Automatic transmission
feature has two modes: PRS and M mode.
Progressive Range Selection (PRS)
Progressive Range Selection gives you the
ability to lockout gears from the automatic
shifting range. This may provide you with an
improved driving experience (for example,
in slippery conditions or when experiencing
a steep grade).
With the gearshift lever in drive (D), press the
– button to active PRS. The available and
selected gears are indicated on the
instrument cluster.
All available gears will display with the
current gear indicated. Press the – button
again to lock out gears beginning with the
highest gear. Example: press the – button
twice to lock out 6th and 5th gears. Only the
available gears will display and the transmission will automatically shift between
the available gears. Press the + button to
unlock gears to allow the transmission to
shift to higher gears. The transmission will
shift automatically within the gear range you
select.
Manual (M)
Moving the gearshift lever to the manual (M)
position will allow you to manually select the
gear you desire. Only the current gear will
display. Use the buttons on the gearshift
lever to manually select gears. Press the +
button to upshift or the – button to downshift.
Return the transmission to a different
gearshift position to deactivate manual
control.
Upshift to the recommended shift speeds

Brake-Shift Interlock WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are working.
When doing this procedure, you will
be taking your vehicle out of park (P)
which means your vehicle can roll freely. To
avoid unwanted vehicle movement, always
fully set the parking brake prior to doing this
procedure. Use wheel chocks if appropriate. WARNINGS
If you fully release the parking brake
and the brake warning lamp remains
illuminated, the brakes may not be working
properly. See your authorized dealer. Your vehicle is equipped with a brake-shift
interlock feature that prevents moving the
gearshift lever from park (P) when the ignition
is in the on position and the brake pedal is
not pressed.
If you cannot move the gearshift lever out of
park (P) position with the ignition in the on
position and the brake pedal pressed, a
malfunction may have occurred. It is possible
that a fuse has blown or your vehicle
’s brake
lamps are not operating properly. See Fuse
Specification Chart (page 250).
If the fuse is not blown and the brake lamps
are working properly, the following
procedure will allow you to move the
gearshift lever from park (P):
1. Apply the parking brake. Turn the ignition
key to the off position, then remove the
key.

making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as the halves rotate together.
If Your Vehicle Gets Stuck In Mud or
Snow
Note: Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute or damage to the transmission and
tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow,
you may rock it out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.

Note: The Control Trac® selector switch
should not be changed while the rear wheels
are slipping. The Control Trac® system functions in three
modes:
•
4X2
delivers power to the rear wheels
only. The information display will
momentarily display 4x2 when this mode
is selected. This mode is appropriate for
normal on-road driving on dry pavement
and provides the best fuel economy.
• 4X4 AUTO
provides electronic control
four-wheel drive with power delivered to
all four wheels, as required, for increased
traction. The information display will
display 4A when this mode is selected.
This mode is appropriate for all on-road
driving conditions, such as dry road
surfaces, wet pavement, snow, or gravel.
• 4X4
provides electronically locked
four-wheel drive power to front and rear
wheels. The information display will
display 4X4 when this mode is selected.
This mode is not recommended for use
on dry pavement. This mode is only
intended for severe winter or off-road
conditions, such as deep snow, ice or
shallow sand. Shifting between system modes
Note:
Momentarily releasing the accelerator
pedal while a shift in progress message
displays will improve
engagement/disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: Some noise may be heard as the
system shifts or engages; this is normal.
Press any button (4X2, 4X4 AUTO or 4X4) at
a stop or while driving. The information
display may display a message indicating a
4X4 shift is in progress. Once the shift is
complete the information display will then

How Your Vehicle Differs From Other
Vehicles
WARNING
Vehicles with a higher center of gravity
such as utility and four-wheel drive
vehicles handle differently than vehicles with
a lower center of gravity. Utility and
four-wheel drive vehicles are not designed
for cornering at speeds as high as passenger
cars any more than low-slung sports cars are
designed to perform satisfactorily under
off-road conditions. Avoid sharp turns,
excessive speed and abrupt maneuvers in
these vehicles. Failure to drive cautiously
could result in an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough terrain
without getting hung up or damaging
underbody components.
The differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car. Maintain steering wheel control at all times,
especially in rough terrain. Since sudden
changes in terrain can result in abrupt
steering wheel motion, make sure you grip
the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the area.
To maintain steering and braking control of
your vehicle, you must have all four wheels
on the ground and they must be rolling, not
sliding or spinning.
Driving Off-Road With Truck and Utility
Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive while
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern. Note:
Your vehicle may be equipped with a
front air dam that can become damaged
(due to reduced ground clearance) when
taking your vehicle off-road. This air dam
can be taken off by removing two bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud and
rough terrain and have operating
characteristics that are somewhat different
from conventional vehicles, both on and off
the road.
Power is supplied to all four wheels through
a transfer case. On Four-wheel drive
vehicles, the transfer case allows you to
select different 4WD modes when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found in the
Maintenance chapter. You should become
thoroughly familiar with this information
before you operate your vehicle.
