on, the compass will show two character boxes for
a few seconds. After a few seconds, the mirror
will display the current compass direction.
Compass Calibration
If after a few seconds the display does not show a
compass direction, (N for North for example), there
may be a strong magnetic eld interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, note pad holder, or
similar object. If the letter C or CAL appears in the
compass window, the compass may need to be
reset or calibrated.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour
(km/h). Your odometer shows how far your vehicle
has been driven, in either miles or kilometers.
Your vehicle has a tamper resistant odometer.
You may wonder what happens if your vehicle
needs a new odometer installed. If the new one
can be set to the mileage total of the old odometer,
then it must be. But if it cannot, then it is set at
zero and a label must be put on the driver’s door to
show the old mileage reading when the new
odometer was installed.
Trip Odometer
A trip odometer can tell you how far you have
driven since you last set it to zero. SeeDriver
Information Center (DIC) on page 212for
information on resetting the trip odometer.
Tachometer
The tachometer tells you how fast the engine is
running. It displays engine speed in thousands of
revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will be provided for several seconds to remind
people to buckle their safety belts. The driver
safety belt light will also be provided and stay on
for several seconds, then it will ash for several
more. You should buckle your seat belt.
This chime and light will
be repeated if the driver
remains unbuckled and
the vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor
the light will be provided.

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light(s) will
come on when your
engine is started and
may stay on for
several seconds.
That’s normal.
If the light stays on, turn the ignition to OFF. Or, if
the light comes on when you’re driving, stop as
soon as possible and turn the ignition off. Then start
the engine again to reset the system. If the light still
stays on, or comes on again while you’re driving,
your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes,
but you don’t have anti-lock brakes. If the regular
brake system warning light is also on, you don’t
have anti-lock brakes and there’s a problem with
your regular brakes. SeeBrake System Warning
Light on page 201.
The anti-lock brake system warning light will come
on briey when you turn the ignition key to RUN.This is normal. If the light doesn’t come on then,
have it xed so it will be ready to warn you if there
is a problem.Traction Control System (TCS)
Warning Light
This warning light
should come on briey
when the engine is
started.
If the warning light does not come on then, have it
xed so it will be ready to warn you if there is a
problem. If it stays on, or comes on when you are
driving a SERVICE TRACTION CONTROL
message will appear in the Driver Information
Center (DIC). This indicates that there may be a
problem with your traction control system and your
vehicle may need service. When this warning light
is on and the SERVICE TRACTION CONTROL
message appears on the DIC, the system will not
limit wheel spin. Adjust your driving accordingly.

DIC Buttons
The buttons are the trip/fuel, vehicle information,
customization, and set/reset buttons. The button
functions are detailed in the following pages.
3(Trip/Fuel):Press this button to display the
odometer, trip odometers, fuel range, average
economy, instantaneous economy, and average
speed.
T(Vehicle Information):Press this button
to display the oil life, park assist on vehicles with
this feature, units, tire pressure readings and Tire
Pressure Monitor (TPM) system programming,
compass zone and compass calibration on vehicles
with this feature, and Remote Keyless Entry (RKE)
transmitter programming.
U(Customization):Press this button to
customize the feature settings on your vehicle.
SeeDIC Vehicle Customization on page 231
for more information.
V(Set/Reset):Press this button to set or reset
certain functions and to turn off or acknowledge
messages on the DIC.
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).
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.
213

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 the
retro-active 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 retro-active 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 retro-active 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 retro-active 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.Fuel Range
Press the trip/fuel button until FUEL RANGE
displays. This display shows the approximate
number of remaining miles (mi) or kilometers (km)
the vehicle can be driven without refueling.
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.
If your vehicle is low on fuel, the FUEL LEVEL
LOW message will be displayed. See “FUEL
LEVEL LOW” underDIC Warnings and Messages
on page 221for more information.
214

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. The display will return to zero.
Instantaneous Economy
Press the trip/fuel button until INST ECONOMY
displays. This display shows the current fuel
economy at a particular moment and will change
frequently as driving conditions change. This
display shows the instantaneous fuel economy in
miles per gallon (mpg) or liters per 100 kilometers
(L/100 km). Unlike average economy, this screen
cannot be reset.
Average Speed
Press the trip/fuel button until AVERAGE 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, press and
hold the set/reset button. The display will return
to zero.
Blank Display
This display shows no information.
