AUTOMATIC TRANSMISSION
WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death.

simultaneously for more than a few
seconds will limit engine performance,
which may result in difficulty maintaining
speed in traffic and could lead to serious
injury.

Putting your vehicle in or out of gear:
1. Fully press the brake pedal.2. Move the gearshift lever into the
preferred gear.
3. When you finish driving, come to a
complete stop.
4. Move the gearshift lever and securely
latch it in park (P) or neutral (N).
The instrument cluster displays the current
gear.
Park (P)
If your transmission has a park (P) position,
this position locks the transmission and
prevents the rear wheels from turning.
Reverse (R)
With the gearshift lever in reverse (R), your
vehicle moves backward. Always come to
a complete stop before shifting into and
out of reverse (R).
Neutral (N)
With the gearshift lever in neutral (N), you
can start your vehicle and it is free to roll.
Hold the brake pedal down when in this
position.
Drive (D)
Drive (D) is the normal driving position for
the best fuel economy. The overdrive
function allows automatic upshifts and
downshifts through gears one through six.
Manual (M)
With the gearshift lever in manual (M), the
driver can change gears up or down as
preferred. By moving the gearshift lever
from drive (D) to manual (M), you now
have control of selecting the gear you
prefer using the buttons on the shift lever.

WHAT IS THE PNEUMATIC
LOCKING DIFFERENTIAL
The pneumatic locking differential can lock
or unlock the differential when the vehicle
is moving or stopped. The differential lock
provides full power to both wheels when
extra traction is required.
HOW DOES THE PNEUMATIC
LOCKING DIFFERENTIAL
WORK
If your vehicle is equipped with a
pneumatic locking differential:
• Power is transmitted to the opposite
wheel should one of the wheels begin
to slip.
• Raise both wheels off the ground if it
becomes necessary to operate one
wheel with the vehicle stationary.
The differential can be locked or unlocked
when the vehicle is moving at a constant
speed of less than 25 mph (40 km/h) and
while the wheels are not slipping. Do not
lock the differential when the vehicle is
traveling down steep grades and traction
is minimal.
Note:Do not use the differential lock at
vehicle speeds above 25 mph (40 km/h).
When the differential is locked, the
vehicle’s turning radius increases causing
understeer.
The differential lock and differential lock
light automatically disengage at speeds
above 25 mph (40 km/h). The differential
lock remains off until the vehicle is
restarted or the differential lock switch is
turned off then back on.
PNEUMATIC LOCKING
DIFFERENTIAL PRECAUTIONS
WARNING: Exceeding any vehicle
weight rating can adversely affect the
performance and handling of your
vehicle, cause vehicle damage and can
result in the loss of control of your
vehicle, serious personal injury or death.
WARNING: Failure to raise all drive
wheels with this type of differential could
cause the vehicle to move unexpectedly,
resulting in property damage, personal
injury or death.
WARNING: Sudden acceleration
on slippery surfaces could cause the
wheels to spin, the vehicle to turn
sideways on a crowned road surface or
in a turn, possibly resulting in loss of
vehicle control and personal injury.
SWITCHING THE PNEUMATIC
LOCKING DIFFERENTIAL ON
AND OFF
Press and hold the button on the dash to
turn the system on or off.
