3. When you finish driving, come to a complete stop.
4. Pull lever toward the driver and move the gearshift lever and securely latch
it in park (P).
MANUALLY SHIFTING GEARS
SHIFTING USING THE BUTTONS
ON THE SELECTOR LEVER
Pressing the manual (M) button on the
shifter allows you to select the gear you
prefer. Only the current gear displays. Press
the + button to upshift or the – button to
downshift. Return the transmission to a
different gearshift position to deactivate
manual control or press manual (M).
Your vehicle has a SelectShift Automatic
transmission gearshift lever. This gives you
the ability to change gears up or down,
without a clutch, as preferred.
Note: To prevent the engine from running
at too low an RPM, which could cause it to
stall, SelectShift still makes some
downshifts if it determines that you have
not downshifted in time. Although
SelectShift makes some downshifts for you,
it still allows you to downshift at any time
if it determines that damage to the engine
from over-revving does not occur.
Note: SelectShift does not automatically
upshift, even if the engine is approaching
the RPM limit. Shift manually by pressing
the
+ button. Note:
Engine damage could occur if you
maintain excessive engine revving without
shifting. BRAKE SHIFT INTERLOCK
WHAT IS BRAKE SHIFT
INTERLOCK
Brake shift interlock prevents you from
shifting out of park (P) when you have
switched the ignition on and not pressed
the brake pedal.

PRECAUTIONS
WARNING:
Do not drive your
vehicle until you verify that the
stoplamps are working. WARNING:
When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheels
chocks if appropriate.

FOUR-WHEEL DRIVE
LIMITATIONS
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components. four-wheel
drive high or four-wheel drive low modes
intended for consistently slippery or loose
surfaces. Use of four low mode on these
surfaces could produce some noise, such
as occasional clunks, but should not
damage drive components. When
transitioning from consistently loose or
slippery surfaces, be sure the four-wheel
drive systems not mechanically blocked
once on dry, hard surfaced roads in
two-wheel drive high.
Operating Four-Wheel Drive with
a Spare or Mismatched tires
On four-wheel drive vehicles, the size of
the spare tire can affect the four-wheel
drive system. If there is a significant
difference between the size of the spare
tire and the remaining tires, you could have
limited four-wheel drive functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed 50 mph (80 km/h) with a
four-wheel drive mode turned on.
• Turn on a four-wheel drive mode
unless the vehicle is stationary.
• Use a four-wheel drive mode on dry
pavement.
When driving with the full-size dissimilar
spare wheel and tire assembly, four-wheel
drive functionality is limited, especially
when driving in a mechanically locked
four-wheel drive mode. You can experience
the following: •
Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked four-wheel drive mode.
Use of a dissimilar spare wheel and tire
assembly can lead to impairment of the
following:
• Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
SELECTING A FOUR-WHEEL
DRIVE MODE The four-wheel drive mode control is on
the instrument panel.
To select a four-wheel drive mode, rotate
the four-wheel drive mode control to
switch to the desired mode. You can select
two-wheel drive high (2H), or four-wheel
drive high (4H), at a stop or while driving.
Once the shift is complete, the information
display then displays the selected
four-wheel drive mode. While shifts are in
progress, you could see messages in the
information display indicating that a shift
is in progress or to release the accelerator
pedal to improve shift performance.

FOUR-WHEEL DRIVE MODES
TWO-WHEEL DRIVE HIGH
Two-wheel drive high is for general
on-road driving. Power's sent to the rear
wheels only.
FOUR-WHEEL DRIVE HIGH
Four-wheel drive high provides
electronically or mechanically locked
four-wheel drive power to both the front
and rear wheels for use in off-road or
winter conditions such as deep snow, sand
or mud. This mode is not for use on dry
pavement.
FOUR-WHEEL DRIVE LOW
Four-wheel drive low provides
electronically or mechanically locked
four-wheel drive power to both the front
and rear wheels for use on low traction
surfaces, but does so with additional
gearing for increased torque multiplication.
This mode is only for off-road conditions
such as deep sand, steep slopes, or pulling
heavy objects.

chances of a loss of vehicle control
which can lead to serious injury or death.
If the rear end of your vehicle slides while
cornering, steer in the direction of the
slide until you regain control of your
vehicle.
Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it cannot stop any faster as
braking occurs at all four wheels. Do not
become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Do not pump the brake
pedal. See Anti-Lock Braking System
Limitations (page 240). Note:
Excessive tire slippage can cause
transmission damage.

WHAT IS HILL START ASSIST
Hill Start Assist makes it easier for you to
pull away when your vehicle is on a slope
without using the parking brake.
HOW DOES HILL START
ASSIST WORK
When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake
pedal to the accelerator pedal. The brakes
release when the engine has developed
sufficient torque to prevent your vehicle
from rolling down the slope.
HILL START ASSIST
PRECAUTIONS
WARNING: The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system turns off if
there is a malfunction or if you
excessively rev the engine. HILL START ASSIST –
