96 Instruments and Controls
Caution
If the vehicle is continually driven
with this light on, the emission
controls might not work as well,
the vehicle fuel economy might
not be as good, and the engine
might not run as smoothly. This
may lead to costly repairs that
might not be covered by the
vehicle warranty.
Modifications made to the engine,
transmission, exhaust, intake,
or fuel system of the vehicle 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.
If the light is flashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill gradients.
If towing a trailer, reduce the
amount of cargo being hauled as
soon as possible.
If the light continues to flash, find a
safe place to park. Turn the engine
off and wait at least 10 seconds
before restarting the engine. If the
light is still flashing, follow the
previous guidelines and see your
dealer for service as soon as
possible.
If the light is on steady : A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
.
If fuel has been added to the
vehicle using the capless fuel
funnel adaptor, make sure that it
has been removed.
The diagnostic system can
detect if the adaptor has been
left installed in the vehicle,
allowing fuel to evaporate into
the atmosphere. A few driving
trips with the adaptor removed
may turn off the light. See
Filling
the Tank 0 246 .
.
Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed
up. If this occurs, change the
fuel brand. It may require at
least one full tank of the correct
fuel to turn the light off. See
Fuel
0 244 .
If the light remains on, see your
dealer.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a problem with the braking
system. Have the brake system
inspected right away.
