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.
See
Manual Mode on page 9‑9.
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.

Driving Information
Steering
This vehicle has On-Demand
Electric-Assist Power Steering
instead of conventional full-time
hydraulic power steering. It uses
electricity supplied by the same
battery which is re-charged by the
regenerative braking system.
Because the system is On-Demand
Electric-Assist, energy is used only
when the steering wheel is turned,
or when the steering gear is used to
help isolate the forces of rough
roads. This system does not use
power steering fluid, making it
maintenance-free.

Driving and Operating 9-3
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. SeeTachometer
on page 5‑4 for more information.
A chime will sound if the driver door
is opened while in Auto Stop as a
reminder that the ignition switch is
not in the LOCK/OFF position.
Always turn the ignition switch to
LOCK/OFF and remove the key
from the ignition switch when exiting
the vehicle.
Auto Start
The vehicle also has an Auto Start
feature. The engine will remain off
while in Auto Stop mode until
vehicle conditions require the
engine to run. The near-instant
starting of the engine from Auto
Stop mode is called Auto Start. Some of the vehicle conditions that
may cause the engine to Auto
Start are:
.The hood is opened.
.The gear selector is in
M (Manual Mode).
.The hybrid battery state of
charge is too low.
.The hybrid battery voltage,
temperature or power limits are
exceeded.
.A remote vehicle start has been
requested.
.The engine is not at operating
temperature.
.Acceleration demands require
the use of the engine.
EV Mode
The vehicle also has an Electric
Vehicle (EV) mode which uses only
the electric motor to move the
vehicle. With light acceleration, the
vehicle will drive in EV mode. EV
mode is unavailable when the
vehicle is out of fuel.
If increased acceleration is
required, or the vehicle reaches
approximately 40 km/h (30 mph), the
engine will start automatically. The
engine shuts off at speeds below
40 km/h (25 mph) unless the
transmission is in M (Manual Mode)
or Auto Stop is disabled.
During heavy acceleration, both the
engine and hybrid electric motors
supply power. A sensation similar to
a transmission gear change can be
felt as the transmission changes
modes. Engine RPM may remain
above 4,000 RPM for a longer
period during hard acceleration.

9-6 Driving and Operating
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake.
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the parking pawl
in the transmission, then you will be
able to pull the shift lever out of
P (Park).Engine Exhaust
Running the Vehicle
While Parked
It is better not to park with the
engine running. But if you ever have
to, here are some things to know.
{WARNING
Exiting the vehicle, without first
shifting into P (Park), may cause
the vehicle to move, and you or
others can be seriously injured.
Because the vehicle has the
Automatic Engine Start/Stop
feature, the vehicle’s engine
might seem to be shut off when
you come to a complete stop.(Continued)
WARNING (Continued)
However, once the brake pedal is
released, the vehicle can move.
The vehicle’s engine can also
restart at any time.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before
exiting the vehicle.
Follow the proper steps to be sure
the vehicle will not move. See
Shifting Into Park on page 9‑4.
If pulling a trailer, see “Driving
Characteristics and Towing Tips” in
the owner manual.

Driving and Operating 9-7
Automatic
Transmission
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” 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 Park on page 9‑4.
{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 on
page 9‑4. If you are pulling a
trailer, see “Driving
Characteristics and Towing Tips”
in the owner manual.
{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
on page 9‑4.

Driving and Operating 9-9
Shifts may be more noticeable with
a cold transmission. This difference
in shifting is normal.
M (Manual Mode):This position
lets drivers select the range of gears
appropriate for current driving
conditions. If the vehicle has this
feature, see Manual Mode on
page 9‑9.
Notice: Spinning the tires or
holding the vehicle in one
place on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.
The vehicle has a shift stabilization
feature that adjusts the transmission
shifting to the current driving
conditions to reduce rapid upshifts
and downshifts. If the shift
stabilization feature determines that
a current vehicle speed cannot be
maintained, the transmission does not upshift. In some cases, this may
appear to be a delayed shift,
however the transmission is
operating normally.
Manual Mode
Range Selection Mode
The Range Selection Mode controls
the vehicle's transmission.
To use this feature:
1. Move the shift lever to the
M (Manual Mode).
2. Press the plus/minus button to upshift or downshift selecting the
desired range of gears.
A number displays next to the M,
indicating the current gear that has
been selected. The number
displayed in the gear indicator is the
highest gear that can be used. The
vehicle can automatically shift to
lower gears as it adjusts to driving
conditions. When 3 (Third) is
selected, 1 (First) through 3 (Third)
gears are automatically shifted by
the vehicle, but 4 (Fourth) cannot be
used until it is selected.
The Range Selection Mode controls
the vehicle and engine speed while
driving down a hill or towing a trailer,
by allowing you to select a desired
range of gears.

9-10 Driving and Operating
When you move the shift lever into
M, the transmission will default to
M4. In this gear range, effective
engine braking occurs at speeds
above 72 km/h (45 mph).
Pushing the minus (−) button on the
shift lever reduces the gear range.
In the M3 gear range, effective
engine braking occurs at speeds
above 56 km/h (35 mph).
In the M2 gear range, effective
engine braking occurs at speeds
above 40 km/h (25 mph).
In the M1 gear range, effective
engine braking occurs at speeds
above 16 km/h (10 mph).
When operating in M (Manual
Mode), Auto Stop is disabled. For
better vehicle efficiency, operate the
vehicle in D (Drive) not
M (Manual Mode).
Cruise control can be used while
using the Range Selection Mode.Drive Systems
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 the
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
owner manual.
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.
