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 10‑36 and“Towing the
Vehicle” in the owner manual.
See Four-Wheel Drive on
page 9‑10.
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.

Climate Control
Systems
For more information on the
vehicle's climate control system, see
“Climate Control System”in the
owner manual.
Electric Air Conditioning
Compressor
This hybrid vehicle has an
electrically powered air conditioning
compressor. This allows for
continuous air conditioning
operation and passenger comfort,
even while the hybrid engine cycles
on and off.
When operating the climate control
system, select the AUTO mode and
the desired temperature setting. The
climate control system automatically
adjusts the fan speed and airflow
direction. The climate control
system continues to adjust the
climate control settings chosen for
best use of electrical power. At mild temperatures, select a
warmer air conditioner temperature
or turn the air conditioner off to get
maximum fuel economy. Continuous
air conditioner use can cause the
vehicle to Auto Start more
frequently. During hot weather,
driving with the windows closed and
the air conditioner set to Auto mode,
will result in better Hybrid system
performance.
Some noise may be heard
occasionally from the compressor,
especially when air conditioning use
is high and the engine has
turned off.

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 9-15
Excessively shifting the transfer
case into or out of the different
modes may cause the transfer case
to enter the shift protection mode.
This will protect the transfer case
from possible damage and will only
allow the transfer case to respond to
one shift per 10 seconds. The
transfer case may stay in this mode
for up to three minutes.Brakes
Regenerative Braking
Regenerative braking is a hybrid
technology that 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, such as when a
high braking demand is requested.The braking system is computer
controlled and blends the
regenerative braking with the
conventional hydraulic disc brakes
to meet any requirements for
deceleration. The controller
interprets the braking request and
uses regenerative braking,
conventional hydraulic braking or a
combination of both as necessary.
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.

10-22 Vehicle Care
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. See“Vehicle Load Limits”
in the owner manual for an
example of the label and its
location on your vehicle.
The Tire Pressure Monitor
System (TPMS) sensors will
need to be reset after a tire
rotation. See “TPMS Sensor
Identification Codes” under“Tire
Pressure Monitor Operation”.
Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
“Capacities and Specifications ”
in the owner manual.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
Tire Chains
{WARNING
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause you to
lose control of the vehicle and
you or others may be injured in a
crash. Use another type of
traction device only if its
manufacturer recommends it for
use on the vehicle and tire size
combination and road conditions.
Follow that manufacturer's
instructions. To help avoid
(Continued)
WARNING (Continued)
damage to the vehicle, drive
slowly, re‐adjust or remove the
device if it is contacting the
vehicle, and do not spin the
wheels. If you do find traction
devices that will fit, install them on
the rear tires.
If a Tire Goes Flat
Your vehicle has a tire inflator kit.
There is no spare tire, no tire
changing equipment, and no place
to store a tire.
It is unusual for a tire to blow out
while you are driving, especially if
you maintain your tires properly.
If air goes out of a tire, it is much
more likely to leak out slowly. But,
if you should ever have a blow out,
here are a few tips about what to
expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
