the light after engine start. The vehicle should
be serviced if the light stays on through several
of your typical driving cycles. In most situa-
tions, the vehicle will drive normally and will not
require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also
could affect fuel economy and drivability. If the
MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Im-
mediate service is required.
WARNING!
A malfunctioning catalytic converter, as refer-
enced above, can reach higher temperatures
than in normal operating conditions. This can
cause a fire if you drive slowly or park over
flammable substances such as dry plants or
wood or cardboard, etc. This could result in
death or serious injury to the driver, occupants
or others.
25. Front Fog Light Indicator — If
Equipped
This indicator will illuminate when the
front fog lights are on.
26. Electronic Stability Control (ESC) OFF
Indicator Light — If Equipped
This light indicates the Electronic
Stability Control system (ESC) has
been turned off by the driver.
27. Electronic Stability Control (ESC)
Malfunction Indicator Light — If Equipped
The "ESC Malfunction Indicator
Light" in the instrument cluster will
come on when the ignition switch
is turned to the ON/RUN position.
It should go out with the engine
running. If the "ESC Malfunction
Indicator Light" comes on continuously with the
engine running, a malfunction has been de-
tected in the ESC system. If this light remains
on after several ignition cycles, and the vehicle
has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to
have the problem diagnosed and corrected.
NOTE:
• The "ESC Off Indicator Light" and the
"ESC Malfunction Indicator Light" come
on momentarily each time the ignition
switch is turned to ON/RUN.
• Each time the ignition is turned to ON/
RUN, the ESC system will be ON even if it
was turned off previously.
• The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
28. 4WD! Malfunction Light
This light monitors the 4-wheel
drive (4WD) system. The light will
come on, for a bulb check, when
the ignition key is turned to the
ON/RUN position and may stay on
for as long as three seconds.
