information about them. For
information on other DIC messages,
see “Vehicle Messages” in the
owner manual.
Battery Voltage and
Charging Messages
SERVICE BATTERY
CHARGING SYSTEM
If the 12V battery system faults or
fails this message will appear on the
DIC. The battery/charging system
light will appear in the instrument
panel cluster. See “Battery Warning
Light” in the owner manual. Driving
with this message on could drain
the battery. Have the electrical
system checked as soon as
possible.
Brake System Messages
SERVICE BRAKE SYSTEM
This message may be displayed if
there is a problem with the brake
system. You will still be able to
brake, but it will be noticeably more

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.

9-8 Driving and Operating
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
the Vehicle is Stuck” in the 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. D (Drive):
This position is for
normal driving. It provides the best
fuel economy. If you need more
power for passing, and you are:
.Going less than about 55 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 55 km/h (35 mph) or
more, push the accelerator all
the way down.
D (Drive) or M (Manual Mode) can
be used when towing a trailer,
carrying a heavy load, driving on
steep hills, or for off-road driving.
You may want to shift the
transmission to a lower gear
selection if the transmission shifts
too often.
Downshifting the transmission in
slippery road conditions could result
in skidding. See “Loss of Control” in
the owner manual.
When temperatures are very cold,
the transmission's gear shifting may
be delayed, providing more stable
shifts until the engine warms up.

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 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.
2
m(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.

Driving and Operating 9-13
Notice:Shifting the transmission
into gear before the Four-Wheel
Drive Low indicator light has
stopped flashing could damage
the transfer case. To help avoid
damaging the vehicle, always wait
for the Four-Wheel Drive Low
indicator light to stop flashing
before shifting the transmission
into gear.
The vehicle may have significant
engagement noise and bump when
shifting between Four-Wheel Drive
Low and Four-Wheel Drive High
ranges or from N (Neutral) while the
engine is running.
If the knob is turned to the
Four-Wheel Drive Low position
when the vehicle is in gear and/or
moving, the Four-Wheel Drive Low
indicator light will flash for
30 seconds and not complete the
shift unless the vehicle is moving
less than 5 km/h (3 mph) and the
transmission is in N (Neutral). After
30 seconds the transfer case will
shift to Four-Wheel Drive
High mode. Shifting Out of Four-Wheel
Drive Low
To shift from Four-Wheel Drive Low
to Four-Wheel Drive High, AUTO,
or Two-Wheel Drive High, the
vehicle must be stopped or moving
less than 5 km/h (3 mph) with the
transmission in N (Neutral) and the
ignition in ON/RUN. The preferred
method for shifting out of
Four-Wheel Drive Low is to have
your vehicle moving 1.6 to 3.2 km/h
(1 to 2 mph). Turn the knob to the
Four-Wheel Drive High, AUTO,
or Two-Wheel Drive High position.
You must wait for the Four-Wheel
Drive High, AUTO, or Two-Wheel
Drive High indicator light to stop
flashing and remain on before
shifting the transmission into gear.
Notice:
Shifting the transmission
into gear before the Four-Wheel
Drive Low indicator light has
stopped flashing could damage
the transfer case. To help avoid damaging the vehicle, always wait
for the Four-Wheel Drive Low
indicator light to stop flashing
before shifting the transmission
into gear.
The vehicle may have significant
engagement noise and bump when
shifting between Four-Wheel Drive
Low and Four-Wheel Drive High
ranges or from N (Neutral) while the
engine is running.
If the knob is turned to the
Four-Wheel Drive High, AUTO,
or Two-Wheel Drive High switch
position when the vehicle is in gear
and/or moving, the Four-Wheel
Drive High, AUTO or Two-Wheel
Drive High indicator light will flash
for 30 seconds but will not complete
the shift unless the vehicle is
moving less than 5 km/h (3 mph)
and the transmission is in
N (Neutral).

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.

10-20 Vehicle Care
.One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer for
service.
.Replacement tires or wheels do
not match your vehicle's original
equipment tires or wheels. Tires
and wheels other than those
recommended for your vehicle
could prevent the TPMS from
functioning properly. See
“Buying New Tires”in the owner
manual.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning it
cannot detect or signal a low tire
condition. See your dealer for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
rotate your vehicle's tires or replace
one or more of the TPMS sensors,
the identification codes will need to
be matched to the new tire/wheel
position. The sensors are matched
to the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire's air pressure. If increasing the
tire's air pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall.
To decrease air-pressure out of a
tire you can use the pointed end of
the valve cap, a pencil-style air
pressure gauge, or a key.
You have two minutes to match
the first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes longer
than two minutes, to match the first
tire and wheel, or more than
five minutes to match all four tire
and wheel positions the matching
process stops and you need to
start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/
RUN with the engine off.
3. Press
QandKon the Remote
Keyless Entry (RKE) transmitter
at the same time for
approximately five seconds. The
horn sounds twice to signal the
receiver is in relearn mode and
