Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone
where you live, the compass may
give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
To adjust for compass variance, use
the following procedure:
Compass Variance (Zone)
Procedure
1. Do not set the compass zonewhen 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 away
from 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.

5-14 Instruments and Controls
Speedometer
The speedometer shows the
vehicle's speed in both kilometers
per hour (km/h) and miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper-resistant
odometer. If the vehicle needs a
new odometer installed, the new
one is set to the mileage of the old
odometer. If this is not possible, it is
set at zero and a label is put on the
driver's door to show the old
mileage reading.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Fuel Gage
United StatesCanada
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 first indicate empty
before the vehicle is out of fuel, but
the vehicle's fuel tank should be
filled soon. When the fuel tank is low on fuel,
the FUEL LEVEL LOW message
appears on the Driver Information
Center (DIC). For more information
see
Fuel System Messages
on
page 5‑34.
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 fill 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 fill the tank.
.The gage goes back to empty
when the ignition is turned off.

5-18 Instruments and Controls
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer/retailer for service.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light
on page 5‑16for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
It should go out when the engine is
started.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer/retailer. Driving while this
light is on could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays the SERVICE BATTERY
CHARGING SYSTEM message.
See Vehicle Messages
on
page 5‑31for more information. If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator Lamp
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.

Instruments and Controls 5-19
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:
Modifications 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. Modifications 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 10‑3.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
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 flash, 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 flashing,
follow the previous steps and see
your dealer/retailer for service as
soon as possible.

5-20 Instruments and Controls
Light On Steady:An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
An emission system malfunction
might be corrected.
.Make sure the fuel cap is fully
installed. See Filling the Tankon
page 9‑42. 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, misfiring,
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.
See Gasoline Specifications
on
page 9‑40.
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
fix 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

5-26 Instruments and Controls

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 miles (mi) or
kilometers (km).
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 miles (mi) or
kilometers (km) since the last reset
for each trip odometer. Both trip
odometers can be used at the
same time. Each trip odometer can be reset to
zero separately by pressing the
set/reset button 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 miles (kilometers) 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
miles (mi) or kilometers (km) 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 5 miles (8 km) before it is
started again, and then the
retroactive reset feature is activated,
the display will show 5 miles (8 km).
As the vehicle begins moving, the
display will then increase to
5.1 miles (8.2 km), 5.2 miles
(8.4 km), etc.
If the retroactive reset feature is
activated after the vehicle is started,
but before it begins moving, the
display will show the number of
miles (mi) or kilometers (km) that
were driven during the last ignition
cycle.
RANGE
Press the trip/fuel button until
RANGE displays. This display
shows the approximate number
of remaining miles (mi) or
kilometers (km) the vehicle can be
driven without refueling. The display
will show LOW if the fuel level
is low.

5-30 Instruments and Controls
The fuel range estimate is based on
an average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank. This estimate will
change if driving conditions change.
For example, if driving in traffic and
making frequent stops, this display
may read one number, but if the
vehicle is driven on a freeway, the
number may change even though
the same amount of fuel is in the
fuel tank. This is because different
driving conditions produce different
fuel economies. Generally, freeway
driving produces better fuel
economy than city driving.
Fuel range cannot be reset.
AVG (Average) ECONOMY
Press the trip/fuel button until AVG
ECONOMY displays. This display
shows the approximate average
miles per gallon (mpg) or liters
per 100 kilometers (L/100 km).This number is calculated based on
the number of mpg (L/100 km)
recorded since the last time this
menu item was reset. To reset AVG
ECONOMY, press and hold the set/
reset button.
TIMER
Press the trip/fuel button until
TIMER displays. This display can be
used as a timer.
To start the timer, press the
set/reset button while TIMER is
displayed. The display will show the
amount of time that has passed
since the timer was last reset, not
including time the ignition is off.
Time will continue to be counted as
long as the ignition is on, even if
another display is being shown on
the DIC. The timer will record up to
99 hours, 59 minutes and
59 seconds (99:59:59) after which
the display will return to zero.
To stop the timer, press the set/reset
button briefly while TIMER is
displayed.To reset the timer to zero, press and
hold the set/reset button while
TIMER is displayed.
FUEL USED
Press the trip/fuel button until FUEL
USED displays. This display shows
the number of gallons (gal) or
liters (L) of fuel used since the last
reset of this menu item. To reset the
fuel used information, press and
hold the set/reset button while FUEL
USED is displayed.
AVG (Average) SPEED
Press the trip/fuel button until AVG
SPEED displays. This display
shows the average speed of the
vehicle in miles per hour (mph) or
kilometers per hour (km/h). This
average is calculated based on the
various vehicle speeds recorded
since the last reset of this value. To
reset the value to zero, press and
hold the set/reset button.
