NOTE: The TSC is disabled when the ESC system is
in the “Partial Off” mode.
WARNING!
• TSC cannot stop all trailers from
swaying. Always use caution when tow-
ing a trailer and follow the tongue weight recom-
mendations. Refer to “TrailerTowing” in “Starting
and Driving” for further information.
• If TSC activates while towing a trailer, stop the
vehicle at the nearest safe location and adjust
the trailer load to eliminate the trailer sway.
• Failure to follow these warnings can result in an
accident or serious personal injury.
ONBOARD DIAGNOSTIC SYSTEM —
OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and auto-
matic transmission control systems. When these sys-
tems are operating properly, your vehicle will provide
excellent performance and fuel economy, as well as
engine emissions well within current government regu-
lations.
If any of these systems require service, the OBD II
system will turn on the “Malfunction Indicator Light”
(MIL). It will also store diagnostic codes and other
information to assist your service technician in making
repairs. Although your vehicle will usually be drivable
and not need towing, see your authorized dealer for
service as soon as possible.
• Prolonged driving with the MIL on
could cause further damage to the emis-
sion control system. It could also affect
fuel economy and drivability.The vehicle must be
serviced before any emissions tests can be per-
formed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
