Charging System Light
This light comes on briefly
when the ignition key is
turned on, but the engine
is not running, as a check
to show it is working.
It should go out once the engine is running. If it stays
on, or comes on while driving, there could be a problem
with the charging system or it could indicate that there
are problems with a generator drive belt, or that there is
an electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light on,
to turn off the accessories, such as the radio and air
conditioner.
Up-Shift Light
The vehicle may have an
up-shift light.
When this light comes on, shift to the next higher gear if
weather, road, and traffic conditions allow.
See Manual Transmission Operation
on page 3‑31for
more information.

If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light can
prevent more serious damage to the vehicle. This
system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with this
light on, after a while, the emission controls might
not work as well, the vehicle's fuel economy might
not be as good, and the engine might not run as
smoothly. This could lead to costly repairs that
might not be covered by the vehicle warranty.
Notice: Modifications made to the engine,
transmission, exhaust, intake, or fuel system of
the vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) 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.
This could also result in a failure to pass a
required Emission Inspection/Maintenance test.
See Accessories and Modifications on page 6‑3. This light comes on during a malfunction in one of
two ways:
Light Flashing:
A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the amount of cargo
being hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still flashing, follow the
previous steps and see your dealer/retailer for
service as soon as possible.

When the ESC system is turned off, the TRACTION
OFF and ESC OFF messages appear, and the
ESC/TCS light comes on to warn the driver that
both traction control and ESC are disabled.
It is recommended that the system remain on for normal
driving conditions, but it may be necessary to turn the
system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to“rock”your vehicle to attempt to
free it. It may also be necessary to turn off the system
when driving in extreme off-road conditions where high
wheel spin is required. See If Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow
on page 5‑23.
ESC may also turn off automatically if it determines that
a problem exists with the system. The ESC OFF and
SERVICE ESC messages and the ESC/TCS light
comes on to warn the driver that ESC is disabled and
requires service. If the problem does not clear after
restarting the vehicle, see your dealer/retailer for
service. See DIC Warnings and Messages
on
page 4‑48for more information.
Adding non‐dealer/non‐retailer accessories can
affect the vehicle's performance. See Accessories and
Modifications
on page 6‑3for more information.
Competitive Driving Mode
(SS Models Only)
The driver can select this optional handling mode by
pressing the ESC/TCS button on the console two times
quickly. COMPETITIVE MODE will be displayed in the
DIC. See DIC Warnings and Messages
on page 4‑48.
Competitive Driving Mode allows the driver to have full
control of the front wheels while the ESC system helps
maintain directional control of the vehicle by selective
brake application. The ESC/TCS light will be on and the
traction control system will not be operating. Adjust your
driving accordingly. This electronic stability control
mode is recommended only for use during closed track
events and competitive driving venues.
When the ESC button is pressed again, or the vehicle is
restarted, the ESC and TCS will be turned back on.
Notice: When traction control is turned off,
or Competitive Driving Mode is active, it is possible
to lose traction. If you attempt to shift with the
front wheels spinning with a loss of traction, it is
possible to cause damage to the transmission.
Do not attempt to shift when the front wheels do
not have traction. Damage caused by misuse of the
vehicle is not covered. See your warranty book for
additional information.
