METRIC or ENGLISH units. All of the vehicle information will then be
displayed in the unit of
measurement selected.
FRONT TIRES or REAR TIRES
On vehicles with the Tire Pressure
Monitor System (TPMS), the
pressure for each tire can be viewed
in the DIC. The tire pressure will be
shown in either kilopascals (kPa) or
pounds per square inch (psi). Press
the vehicle information button until
the DIC displays FRONT
TIRES kPa (PSI) LEFT ##
RIGHT ##. Press the vehicle
information button again until the
DIC displays REAR TIRES kPa
(PSI) LEFT ## RIGHT ##.
If a low tire pressure condition is
detected by the system while
driving, a message advising you
add air to a specific tire will appear
in the display. See
Tire Pressure on
page 10-44 andTire Messages on
page 5-39 for more information.

If the tire pressure display shows
dashes instead of a value, there
may be a problem with your vehicle.
If this consistently occurs, see your
dealer for service.
COMPASS ZONE SETTING
This display will be available if the
vehicle has a compass. See
Compass on page 5-4for more
information.

Blank Display
This display shows no information.Trip/Fuel Menu Items
3(Trip/Fuel): Press this button
to scroll through the following menu
items:
ODOMETER
Press the trip/fuel button until
ODOMETER displays. This display
shows the distance the vehicle has
been driven in either kilometers (km)
or miles (mi). Pressing the trip
odometer reset stem will also
display the odometer.
To switch between English and
metric measurements, see “UNITS”
earlier in this section.
TRIP A and TRIP B
Press the trip/fuel button until
TRIP A or TRIP B displays. This
display shows the current distance
traveled in either kilometers (km) or
miles (mi) since the last reset for
each trip odometer. Both trip
odometers can be used at the same
time. Pressing the trip odometer
reset stem will also display the trip
odometers. Each trip odometer can be reset to
zero separately by pressing the set/
reset button or the trip odometer
reset stem while the desired trip
odometer is displayed.
The trip odometer has a feature
called retroactive reset. This can be
used to set the trip odometer to the
number of kilometers (miles) driven
since the ignition was last turned on.
This can be used if the trip
odometer is not reset at the
beginning of the trip.
To use the retroactive reset feature,
press and hold the set/reset button
for at least four seconds. The trip
odometer will display the number of
kilometers (km) or miles (mi) driven
since the ignition was last turned on
and the vehicle was moving. Once
the vehicle begins moving, the trip
odometer will accumulate mileage.
For example, if the vehicle was
driven 8 km (5 mi) before it is started
again, and then the retroactive reset
feature is activated, the display will
show 8 km (5 mi). As the vehicle

System on page 10-46, and Tire
Pressure on page 10-44 for more
information.
Transmission Messages
ALL WHEEL DRIVE OFF
If your vehicle has the All-Wheel
Drive (AWD) system, this message
displays when there is a temporary
condition making the AWD system
unavailable. The vehicle will run in
2WD. This could be caused by:
.A compact spare tire on the
vehicle
.AWD system overheat
.Loss of wheel or vehicle speed
.Certain other vehicle electrical
conditions
This message turns off when the
compact spare tire is replaced by a
full-size tire, the differential fluid
cools or the above conditions are no
longer present and the warning
message is reset. To reset the
warning message manually, turn the
ignition off and then back on again
after 30 seconds. If the message
stays on, see your dealer. See
All-Wheel Drive on page 9-25.
SERVICE ALL WHEEL DRIVE
This message displays if a problem
occurs with the All-Wheel Drive
(AWD) system. The vehicle will run
in 2WD. This could be caused by:
.An electronics problem
.Worn out or overheated clutch
plates
.Various electrical issues
If this message appears, stop as
soon as possible and turn off the
ignition for 30 seconds. Restart the
vehicle and check for the message

9-10 Driving and Operating
Vehicle Load Limits
It is very important to know how
much weight your vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on your vehicle show
how much weight it may
properly carry, the Tire and
Loading Information label and
the Certification/Tire label.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
(Continued)
Warning (Continued)
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
shorten the life of the vehicle.
Tire and Loading Information
Label
Example Label
A vehicle-specific Tire and
Loading Information label is
attached to the center pillar
(B-pillar). The tire and loading information label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
size of the original equipment
tires (3) and the recommended
cold tire inflation pressures (4).
For more information on tires
and inflation see
Tires on
page 10-37 andTire Pressure
on page 10-44.
There is also important loading
information on the vehicle
Certification/Tire label. It tells
you the Gross Vehicle Weight
Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for
the front and rear axle. See
“Certification/Tire Label” later in
this section.

9-22 Driving and Operating
Automatic
Transmission
P (Park):This position locks the
front wheels. It is the best position
to use when starting the engine
because the vehicle cannot move
easily.
{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. 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 9-19 andDriving
Characteristics and Towing Tips
on page 9-46.
Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. With the ignition in ON/
RUN, fully apply the regular brake, then press the button on the back of
the shift lever before shifting from
P (Park). If you cannot shift out of
P (Park), ease pressure on the shift
lever, then push the shift lever all
the way into P (Park) as you
maintain brake application. Then
press the shift lever button and
move the shift lever into another
gear. See
Shifting out of Park on
page 9-20.
R (Reverse): Use this gear to
back up.
{Caution
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.

9-26 Driving and Operating
Brakes
Antilock Brake
System (ABS)
This vehicle has ABS, an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
might be heard while this test is
going on, and it might even be
noticed that the brake pedal moves
a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5-19. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.
