When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means you
have a brake problem.
If the light comes on while you are driving, pull
off the road and stop carefully. You may notice that
the pedal is harder to push, or the pedal may go
closer to the oor. It may take longer to stop.
If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 340.
{CAUTION:
Your brake system may not be working
properly if the brake system warning
light is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light will
come on when your
engine is started
and may stay on for
several seconds.
That is normal.
If the ABS warning light comes on and stays on,
there may be a problem with the antilock portion
of the brake system. If the red BRAKE light is
not on, you still have brakes, but you do not have
antilock brakes. SeeBrake System Warning
Light on page 229.
If the light stays on, turn the ignition to OFF or
ACCESSORY. If the light comes on when you are
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 are driving, your vehicle needs
service. If the regular brake system warning light
is not on, you still have brakes, but you do not
have anti-lock brakes.

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on when
the engine is very hot.
This light will also come on briey when the
vehicle is started.
If the light does not go out or comes on and stays
on while driving, there may be a problem with
the cooling system. Driving with engine coolant
temperature light on could cause your vehicle
to overheat, seeOverheated Engine Protection
Operating Mode on page 379. SeeEngine
Overheating on page 377andDIC Warnings and
Messages on page 246for more information.
Engine Coolant Temperature Gage
This gage shows
the engine coolant
temperature.
It indicates when the engine has warmed up and
if the cooling system is operating properly. If
the gage pointer moves into the shaded area,
the engine coolant is too hot and the engine
coolant temperature warning light will come on.
SeeEngine Overheating on page 377for
more information.

Fuel Gage
The fuel gage shows
approximately how
much fuel is in the tank.
It works only when
the engine is on.
If the fuel supply gets low, the FUEL LEVEL LOW
message will appear in the Driver Information
Center and a single chime will sound. SeeDIC
Warnings and Messages on page 246for more
information.Here are a few concerns some owners have had
about the fuel gage. All of these situations are
normal and do not indicate that anything is wrong
with the fuel gage:
At the gas station the gas pump shuts off
before the gage reads full.
The gage may change when you turn, stop
quickly or accelerate quickly.
It takes a little more or less fuel to ll the
tank than the gage indicated. For example, the
gage may have indicated that the tank was
half full, but it actually took a little more or less
than half the tank’s capacity to ll the tank.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC
is also used to display warning/status messages.
All messages will appear in the DIC display located
at the bottom of the instrument panel cluster, below
the tachometer and speedometer. The DIC buttons
are located on the instrument panel, to the left of
the steering wheel.
The DIC comes on when the ignition is on. After
a short delay, the DIC will display the information
that was last displayed before the engine was
turned off.
The top line of the DIC display shows the vehicle
system information and the warning/status
messages. The bottom line of the DIC display
shows the odometer on the left side. The bottom
line of the DIC display also shows a digital
speedometer on the right side.
If a problem is detected, a warning message
will appear on the display. Be sure to take any
message that appears on the display seriously
and remember that clearing the message will only
make the message disappear, not correct the
problem.
DIC Controls and Displays
The Driver Information
Center (DIC) has
different displays
which can be accessed
by pressing the DIC
buttons located on the
instrument panel, to the
left of the steering wheel.

up and down the menu items.
Trip/Fuel Display Menu Items
3
(Trip/Fuel):The following display menu
items can be displayed by pressing the trip/fuel
button:
TRIP A or TRIP B
These displays show the current distance traveled
since the last reset for each trip odometer in either
miles (mi) or kilometers (km). Both odometers can
be used at the same time. Each trip odometer can
be reset to zero separately by pressing and holding
the set/reset button for a few seconds while the
desired trip odometer is displayed.
FUEL RANGE
This display shows the approximate number
of remaining miles (mi) or kilometers (km) you can
drive without relling the fuel tank. This estimate
is based on the current driving conditions and
will change if the driving conditions change.
For example, if you are driving in traffic and
making frequent stops, the display may read
one number, but if you enter the freeway,
the number may change even though you still
have the same amount of fuel in the fuel tank.
This is because different driving conditions
produce different fuel economies. Generally,
freeway driving produces better fuel economy
than city driving.
Once the range drops below an estimated
40 miles (64 km) remaining, the display will
show FUEL RANGE LOW.
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 246for more information.

BATTERY VOLTAGE
This display shows the current battery voltage.
If the voltage is in the normal range, the value
will display. For example, the display may read
BATTERY VOLTAGE 13.2 VOLTS. If the voltage
is low, the display will show LOW. If the voltage is
high, the display will show HIGH. Your vehicle’s
charging system regulates voltage based on the
state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal. SeeCharging System Light on
page 229for more information.
If there is a problem with the battery charging
system, the DIC will display a message. SeeDIC
Warnings and Messages on page 246and
Electric Power Management on page 201for
more information.

LIFE REMAINING on the display, that means that
99% of the current oil life remains.
When the oil life is depleted, the CHANGE ENGINE
OIL SOON message will appear on the display.
You should change the oil as soon as possible.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is recommended
in the Maintenance Schedule in this manual. See
Scheduled Maintenance on page 465andEngine
Oil on page 365.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
