Initial Drive Information
Transmission
Range Selection Mode
The Range Selection Mode switch is located on the
shift lever. To enable the Range Selection feature,
move the column shift lever to the M (Manual) position.The current range will appear next to the M. This is the
highest attainable range with all lower gears accessible.
As an example, when 3 (Third) gear is selected, 1 (First)
through 3 (Third) gears are available.
Press the plus/minus buttons, located on the steering
column shift lever, to select the desired range of
gears for current driving conditions. See Automatic
Transmission Operation in the owner manual.
Cruise control can be used while the vehicle is in
Range Selection Mode.
Four-Wheel Drive
If the vehicle has four-wheel drive, you can send
the engine's driving power to all four wheels for
extra traction. Read the following before using
four-wheel drive.
1-2

Automatic Transfer Case
The transfer case knob is located to the left of the
instrument panel cluster. You can choose among
five driving settings:
2
m(Two-Wheel Drive High):This setting is used for
driving in most street and highway situations.
AUTO (Automatic Four-Wheel Drive) : This setting is
ideal for use when road surface traction conditions are
variable.
4
m(Four-Wheel Drive High): Use the four-wheel high
position when you need extra traction, such as on
snowy or icy roads or in most off-road situations. 4
n(Four-Wheel Drive Low) :
This setting delivers
extra torque. You might choose Four-Wheel Drive Low if
you are driving off-road in deep sand, deep mud, deep
snow, and while climbing or descending steep hills.
N (Neutral) : Shift the vehicle's transfer case to
N (Neutral) only when towing the vehicle. See
Recreational Vehicle Towing or Towing Your Vehicle
in the index of the Owner Manual.
See Four-Wheel Drive on page 3‑10.
Hybrid Features
Hybrid Safety Information
This vehicle has a standard 12-volt battery and a
high-voltage hybrid battery. Only a trained service
technician with the proper knowledge and tools should
inspect, test, or replace the hybrid battery. See your
dealer/retailer if the hybrid battery needs service.
The 12-volt battery cables, in the engine compartment,
are clearly labeled. In emergency situations, first
responders can cut those cables to disable the
high-voltage hybrid battery system.

Automatic Transmission Operation
The vehicle has an electronic shift position indicator
within the instrument panel cluster.
There are several different positions for the shift lever.
See“Range Selection Mode” later in this section.
P (Park) : This position locks the rear wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
When parked on a hill, especially when the vehicle has
a heavy load, you may notice an increase in the effort to
shift out of P (Park). See “Shifting Into P (Park)”in the
Index of vehicle's owner manual for more information.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park in the Owner Manual. If you are pulling a
trailer, see Towing a Trailer on page 5‑8.
3-6

{WARNING:
If you have Four-Wheel Drive, the vehicle will
be free to roll—even if the shift lever is in
P (Park) —if the transfer case is in Neutral.
So, be sure the transfer case is in a drive gear,
Two-Wheel Drive High or Four-Wheel Drive High
or Four-Wheel Drive Low —not in Neutral.
See “Shifting Into Park” in the Owner Manual.
R (Reverse) : Use this gear to back up.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission, see
“If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow” in
the Index of the vehicle's owner manual. N (Neutral) :
In this position, the engine and
transmission are not connected with the wheels.
To restart the engine when the vehicle is already
moving, use N (Neutral) only.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice: Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
3-7

Four-Wheel Drive
If the vehicle has four-wheel drive, you can send the
engine's driving power to all four wheels for extra
traction. Read the following before using four-wheel
drive.
Notice:Driving on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive Low for
an extended period of time may cause premature
wear on your vehicle's powertrain. Do not drive on
clean, dry pavement in Four-Wheel-Drive High or
Four-Wheel-Drive Low for extended periods of time.
While driving on clean dry pavement and during tight
turns, you may experience a vibration in the steering
system.
The vehicle has StabiliTrak
®. Shifting into
Four-Wheel-Drive Low will turn Traction Control and
StabiliTrak
®off. See StabiliTrak®System in the index
of the Owner Manual for more information.
Front Axle
The front axle engages and disengages automatically
when you shift the transfer case. Some delay for the
axle to engage or disengage is normal.
Automatic Transfer Case
The transfer case knob is
located to the left of the
instrument panel cluster.
Use this dial to shift into and out of four-wheel drive.
You can choose among five driving settings:
Indicator lights in the switches show you which setting
you are in. The indicator lights will come on briefly
when you turn on the ignition and the last chosen
setting will stay on. If the lights do not come on, you
should take the vehicle to your dealer/retailer for
service. An indicator light will flash while shifting. It will
stay on when the shift is completed. If for some reason
the transfer case cannot make a requested shift, it will
return to the last chosen setting.

2m(Two-Wheel Drive High):This setting is used for
driving in most street and highway situations. The front
axle is not engaged in two-wheel drive. This setting also
provides the best fuel economy.
AUTO (Automatic Four-Wheel Drive) : This setting is
ideal for use when road surface traction conditions are
variable. When driving your vehicle in AUTO, the front
axle is engaged, but the vehicle's power is primarily
sent to the rear wheels. When the vehicle's software
determines a need for more traction, the system will
transfer more power to the front wheels. Driving in this
mode results in slightly lower fuel economy than
Two-Wheel Drive High.
4
m(Four-Wheel Drive High): Use the four-wheel high
position when you need extra traction, such as on
snowy or icy roads or in most off-road situations.
This setting also engages the front axle to help drive
the vehicle. This is the best setting to use when
plowing snow.
4
n(Four-Wheel Drive Low) : This setting also
engages the front axle and delivers extra torque.
You may never need this setting. It sends maximum
power to all four wheels. You might choose Four-Wheel
Drive Low if you are driving off-road in deep sand, deep
mud, deep snow, and while climbing or descending
steep hills. The vehicle has StabiliTrak
®. Shifting into
Four-Wheel-Drive Low will turn Traction Control and
StabiliTrak
®off. See StabiliTrak®System in the index
of the Owner Manual for more information.
{WARNING:
Shifting the transfer case to N (Neutral) can cause
the vehicle to roll even if the transmission is in
P (Park). You or someone else could be seriously
injured. Be sure to set the parking brake before
placing the transfer case in N (Neutral). See
Parking Brake in the index of the Owner Manual
for more information.
N (Neutral) : Shift the vehicle's transfer case to
N (Neutral) only when towing the vehicle. See
Recreational Vehicle Towing or Towing Your Vehicle in
the index of the Owner Manual.
If the SERVICE 4 WHEEL DRIVE message stays on,
you should take the vehicle to your dealer/retailer for
service. See DIC Warnings and Messages
on
page 4‑12for more information.
