Brake System Warning Light
MetricEnglish
The vehicle brake system consists of
electronically controlled hydraulic brake
circuits. If a fault is detected, valves are
adjusted to allow the brake pedal to push
brake fluid directly into the hydraulic brake
circuits. When a fault occurs, the brake system
warning light comes on, and Driver
Information Center (DIC) messages may
display.
Vehicle speed may also be limited and the
amount of brake pedal force applied may
need to increase. Have the vehicle brake
system serviced as soon as possible.
This light should come on briefly when the
engine is started. If it does not come on
then, have it fixed so it will be ready to
warn if there is a problem.
The brake system warning light may also
come on when the parking brake is set,
if the vehicle has low brake fluid, or if the
brakes are severely faded. See
Brake Fluid
0 260. If the brakes are overheated, DIC
messages may display, and the vehicle
speed may be limited. If the brake fluid is
not low, if the brakes are not overheated,
and if the parking brake is fully released,
then the vehicle has a brake problem.
Have the vehicle brake system serviced as
soon as possible.
If the light comes on while driving, pull off
the road and stop carefully. The pedal might
be harder to push, or the pedal may go
closer to the floor. It could take longer to stop. If the light is still on, have the vehicle
towed for service. See
Towing the Vehicle
0 304.
{Warning
The brake system might not be working
properly if the brake system warning
light is on. Driving with the brake system
warning light on can lead to a crash.

Engine Oil Pressure Light
Oil pressure can vary with engine speed,
outside temperature, and oil viscosity.
On some models, the oil pump will vary
engine oil pressure according to engine
needs. Oil pressure may change quickly as
the engine speed or load varies. This is
normal. If the oil pressure warning light or
Driver Information Center (DIC) message
indicates oil pressure outside the normal
operating range, check the vehicle's oil as
soon as possible.
Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is
still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.
This light should come on briefly as the
engine is started. If it does not come on,
have the vehicle serviced by your dealer.
If the light comes on and stays on, it means
that oil is not flowing through the engine
properly. The vehicle could be low on oil
and might have some other system
problem. See your dealer.
Low Fuel Warning Light
This light is near the fuel gauge and comes
on briefly when the ignition is turned on as
a check to show it is working.
It also comes on when the fuel tank is low
on fuel. The light turns off when fuel is
added. If it does not, have the vehicle
serviced.
Security Light
The security light should come on briefly as
the engine is started. If it does not come on,
have the vehicle serviced by your dealer.
If the system is working normally, the
indicator light turns off.
