all accessories, such as the
radio and air conditioner.
Voltmeter Gage
When the engine is not running, but
the ignition is on, this gage shows
the battery’s state of charge in
DC volts.
When the engine is running, this
gage shows the condition of
the charging system. The vehicle’s
charging system regulates
voltage based on the state of
charge of the battery. The voltmeter
may uctuate. This is normal.
Readings between the low and high
warning zones indicate the normal
operating range.Readings in the low warning zone
may occur when a large number
of electrical accessories are
operating in the vehicle and the
engine is left idling for an extended
period.
If there is a problem with the battery
charging system, a SERVICE

as possible.
Brake System Warning
Light
This vehicle’s hydraulic brake
system is divided into two parts. If
one part is not working, the
other part can still work and stop
the vehicle. For good braking
both parts need to be working.
If the warning light comes on, there
is a brake problem. Have the
brake system inspected right away.
This light should come on briey
when the ignition key is turned
to ON/RUN. If it does not come on
then, have it xed so it will be
ready to warn if there is a problem.

When the ignition is on, the brake
system warning light will also
come on when the parking brake is
set. The light will stay on if the
parking brake does not release fully.
If it stays on after the parking
brake is fully released, it means
there is a brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
Make sure the parking brake is
fully released. The pedal may be
harder to push or, the pedal may go
closer to the oor. It may take
longer to stop. If the light is still on,

page 5-20for more information.
Tire Pressure Light
The tire pressure light should come
on briey as the engine is started.
If it does not, have the vehicle
service by your dealer/retailer. It
provides information about tire
pressures and the Tire Pressure
Monitoring System.When the Light is On Steady
This indicates that one or more of
the tires are signicantly
underinated.
A tire pressure message in the
Driver Information Center (DIC),
may accompany the light. SeeDIC
Warnings and Messages on
page 3-48for more information.
Stop and check the tires as soon as
it is safe to do so. If underinated,
inate to the proper pressure.
SeeTires on page 5-36for more
information.
When the Light Flashes First and

Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on when the ignition
is on, but the engine is not running,
as a check to show it is working. If it
does not, have the vehicle serviced
by your dealer/retailer.
3-36 Instrument Panel

If the check engine light comes on
and stays on, while the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem
is apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system
assists the service technician in
correctly diagnosing any
malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle’s fuel economy
might not be as good, and the
engine might not run as
smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.Notice:Modications made to
the engine, transmission,
exhaust, intake, or fuel system of
the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle’s emission
controls and can cause this light
to come on. Modications to
these systems could lead
to costly repairs not covered by
the vehicle warranty. This
could also result in a failure to
pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications
on page 5-3.
This light comes on during a
malfunction in one of two ways:
Light Flashing:A misre condition
has been detected. A misre
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
If the light continues to ash, when it
is safe to do so, stop the vehicle.
Find a safe place to park the vehicle.
Turn the key off, wait at least
10 seconds, and restart the engine. If
the light is still ashing, follow the
previous steps and see your dealer/
retailer for service as soon as
possible.
Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
Instrument Panel 3-37

An emission system malfunction
might be corrected by:
Make sure the fuel cap is fully
installed. SeeFilling the Tank on
page 5-7. The diagnostic system
can determine if the fuel cap
has been left off or improperly
installed. A loose or missing fuel
cap allows fuel to evaporate into
the atmosphere. A few driving
trips with the cap properly
installed should turn the light off.
If the vehicle has been driven
through a deep puddle of water,
the vehicle’s electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out. A
few driving trips should turn the
light off.
Make sure to fuel the vehicle with
quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misring,hesitation on acceleration, or
stumbling on acceleration. These
conditions might go away once
the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand
used. It will require at least one
full tank of the proper fuel to turn
the light off.
SeeGasoline Octane on
page 5-5.
If none of the above have made the
light turn off, your dealer/retailer can
check the vehicle. The dealer/retailer
has the proper test equipment and
diagnostic tools to x any mechanical
or electrical problems that might
have developed.
Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection could
prevent getting a vehicle registration.Here are some things to know to
help the vehicle pass an inspection:
The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in
ON/RUN and the light is not on.
The vehicle will not pass this
inspection if the OBD II (on-board
diagnostic) system determines
that critical emission control
systems have not been
completely diagnosed by the
system. The vehicle would be
considered not ready for
inspection. This can happen if the
battery has recently been
replaced or if the battery has run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
3-38 Instrument Panel

If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer/
retailer can prepare the vehicle for
inspection.
Oil Pressure Light
{CAUTION
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches re.
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 in this manual for
changing engine oil.The oil pressure light should come
on briey as the engine is started.
If it does not come on have the
vehicle serviced by your
dealer/retailer.
If the light comes on and stays on, it
means that oil is not owing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
Security Light
This light ashes when the security
system is activated.
For more information, see
Theft-Deterrent Systems on
page 2-16.
Fog Lamp Light
The fog lamp light comes on when
the fog lamps are in use.
The light goes out when the fog
lamps are turned off. SeeFog Lamps
on page 3-14for more information.

Cruise Control Light
This light comes on whenever the
cruise control is set.
The light goes out when the cruise
control is turned off. SeeCruise
Control on page 3-10for more
information.
Highbeam On Light
The highbeam on light comes on
when the high-beam headlamps are
in use.
SeeHeadlamp High/Low-Beam
Changer on page 3-7for more
information.
Tow/Haul Mode Light
This light comes on when the
Tow/Haul mode has been activated.
For more information, see
Tow/Haul Mode on page 2-26.
Fuel Gage
When the ignition is on, the fuel
gage shows about how much fuel
the vehicle has left in the fuel tank.
An arrow on the fuel gage indicates
the side of the vehicle the fuel door
is on.The gage will rst indicate empty
before the vehicle is out of fuel, but
the vehicle’s fuel tank should be
lled soon.
When the fuel tank is low on fuel,
the FUEL LEVEL LOW message
appears on the Driver Information
Center (DIC). For more information
seeDIC Warnings and Messages
on page 3-48.
Here are some situations that can
occur with the fuel gage. None
of these indicate a problem with the
fuel gage.
At the gas station, the fuel
pump shuts off before the gage
reads full.
It takes a little more or less fuel
to ll up than the fuel gage
indicated. For example, the gage
may have indicated the tank
was half full, but it actually took a
little more or less than half the
tank’s capacity to ll the tank.
The gage goes back to empty
when the ignition is turned off.

Procedure
1. Do not set the compass zone
when the vehicle is moving.
Only set it when the vehicle is in
P (Park).
Press the vehicle information
button until PRESS
VTO
CHANGE COMPASS ZONE
displays.2. Find the vehicle’s current
location and variance zone
number on the map.
Zones 1 through 15 are available.
3. Press the set/reset button
to scroll through and select the
appropriate variance zone.
4. Press the trip/fuel button until the
vehicle heading, for example,
N for North, is displayed in
the DIC.
5. If calibration is necessary,
calibrate the compass. See
“Compass Calibration Procedure”
following.
Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an open
parking lot, where driving the
vehicle in circles is not a danger. It
is suggested to calibrate awayfrom tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated.
If the DIC display does not show a
heading, for example, N for
North, or the heading does not
change after making turns, there
may be a strong magnetic eld
interfering with the compass. Such
interference may be caused by
a magnetic CB or cell phone
antenna mount, a magnetic
emergency light, magnetic note pad
holder, or any other magnetic
item. Turn off the vehicle, move the
magnetic item, then turn on the
vehicle and calibrate the compass.
