crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If this warning light stays on after the engine is started,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-32
to see if it is set. If the parking brake is not set, have
the brake system inspected right away.
If the light comes on while driving and a CHECK
BRAKE FLUID message shows on the DIC, pull off the
road and stop carefully. The pedal may be harder to
push or the pedal may go closer to the oor. It may take

has right now and will change frequently as driving
conditions change. Unlike average fuel economy,
this menu item cannot be reset.
Press the fuel button again to display instantaneous
fuel economy, such as:
INSTANT FUEL ECONOMY 20.1 MPG or

distance you can drive without refueling. It is based on
fuel economy and the fuel remaining in the tank.
Press the fuel button again to display the range,
such as:
RANGE 30 MI or
RANGE 48 km
If the LOW FUEL warning is displayed or if RANGE
is less than 40 miles (64 km), the display will read
RANGE LOW.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your driving
conditions change, this data is gradually updated
automatically.If the vehicle has been idling for a long time, the range
displayed on the DIC could be abnormally low.
The vehicle must be driven 5–10 miles (8–16 km) to
get an accurate reading.
