Antilock Brake System (ABS)
Warning Light
The Antilock Brake
System (ABS) light comes
on briefly when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 4-27.

Engine Coolant Temperature
Warning Light
This light comes on briefly
while starting the vehicle.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally
the indicator light goes off.
Notice:Driving with the engine coolant temperature
warning light on could cause the vehicle to overheat.
SeeEngine Overheating on page 6-29. The vehicle’s
engine could be damaged, and it might not be
covered by the vehicle warranty. Never drive with
the engine coolant temperature warning light on.
The engine coolant temperature warning light comes on
when the engine has overheated.

Tire Pressure LightFor vehicles with a tire pressure monitoring system,
this light comes on briefly when the engine is started.
It provides information about tire pressures and the
Tire Pressure Monitoring System.When the Light is On SteadyThis indicates that one or more of the tires are
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC) on page 4-37for more
information. Stop and check the tires as soon as it is safe
to do so. If underinflated, inflate to the proper pressure.
SeeInflation - Tire Pressure on page 6-59for more
information.
When the Light Flashes First and Then is
On SteadyThis indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about
a minute and stays on steady for the remainder of
the ignition cycle. This sequence repeats with every
ignition cycle. SeeTire Pressure Monitor Operation
on page 6-62for more information.Malfunction Indicator LampCheck Engine LightA 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 should come 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.
4-31

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 6-3.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.
To 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.

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 RangePress 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 displays. See “FUEL LEVEL LOW” underDIC
Warnings and Messages on page 4-44for more
information.
Average EconomyPress 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 this display to zero, press
and hold the set/reset button.Instantaneous EconomyPress 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 SpeedPress 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 DisplayThis display shows no information.
