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.

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

off until the ignition key is placed in the START position
or a remote vehicle start is performed. When the
tachometer needle indicates AUTO STOP, the hybrid
system is on, the engine is not running, but may Auto
Start at any time without notice. See Tachometer
on
page 4‑4for more information.
