Information Transmission Range Selection Mode
The Range Selection Mode switch
is located on the shift lever.
To enable the Range Selection
feature:
1. 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.
2. 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 ‑ 10 .
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 In Brief 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 on
page 10 ‑ 33 and “ Towing the
Vehicle ” in the owner manual.
See Four-Wheel Drive on
page 9 ‑ 11 .Hybrid Features High Voltage 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 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.

1-4 In Brief 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. EV Mode The vehicle also has an 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.
For more information on Auto Stop,
Auto Start, and EV Mode, see
Starting the Vehicle on page 9 ‑ 2 .
Regenerative Braking Regenerative braking enables the
electric drive motor to operate as a
generator when coasting or braking.
Energy from the moving vehicle
recharges the hybrid battery.
The hydraulic disc brakes work with
the regenerative braking to insure
effective braking. The braking system is computer
controlled and blends the
regenerative braking with the
conventional hydraulic disc brakes
to meet any requirements for
deceleration. Because the controller
applies the hydraulic brakes through
its high pressure accumulator, you
may occasionally hear the motor
driven pump when it recharges the
system. This is normal. In the event
of a controller problem, the brake
pedal may be harder to push and
the stopping distance may be
longer.
See Regenerative Braking on
page 9 ‑ 15 .

In Brief 1-5
Battery This vehicle has a standard 12-volt
battery and a high voltage hybrid
battery. When a new standard
12-volt battery is needed, see
your dealer for one that has the
replacement number shown on
the original battery's label. Only a
trained service technician with the
proper knowledge and tools should
inspect, test, or replace the hybrid
battery. See your dealer if the hybrid
battery needs service. See Battery
on page 10 ‑ 11 . Service Never try to do your own service on
hybrid components. You can be
injured and the vehicle can be
damaged if you try to do your own
service work. Service and repair of
these hybrid components should
only be performed by a trained
service technician with the proper
knowledge and tools. See Doing
Your Own Service Work on
page 10 ‑ 2 .
Performance and
Maintenance Tire Sealant and
Compressor Kit This vehicle has a tire sealant and
compressor kit that can be used to
seal small punctures in the tread
area of the tire. Significant sidewall
damage will require the tire to be
replaced.
See Tire Sealant and Compressor
Kit on page 10 ‑ 22 for complete
operating information.

Charging System Light
This 12 ‐ volt battery light comes on
briefly when the ignition is turned to
ON/RUN, but the engine is not
running, as a check to show it is
working.
It should go out once the engine
has been started. If it stays on,
or comes on while driving, there
could be a problem with the 12 ‐ volt
charging system. Have the vehicle
serviced by your dealer. A 12 ‐ volt
charging system Driver Information
Center (DIC) message may also
appear. See Driver Information
Center (DIC) on page 5 ‑ 5 for more
information. This light could indicate
that there are electrical problems.
Have it checked right away. If a short distance must be driven with
the light on, be certain to turn off all
the accessories.
Engine Oil Pressure Light
{ WARNINGDo not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil. This light comes on briefly as a
check it works, when the ignition is
in ON/RUN. If it does not, have the
vehicle serviced.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
During an Auto Stop there is zero
oil pressure, but this light will not
come on.
