EMERGENCIES
• If the MIL flashes when the engine is running, serious conditions may exist that
could lead to immediate loss of power or severe catalytic converter damage. We
recommend you do not operate the vehicle. Have the vehicle serviced immediately.
- Electronic Stability Control (ESC) Activation/Malfunction Indicator Light
• If the "ESC Activation/Malfunction Indicator Light" comes on continuously with
the engine running, a malfunction has been detected 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), we recom-
mend you drive to the nearest service center and have the vehicle serviced
immediately.
• The "ESC Activation/Malfunction Indicator Light" starts to flash as soon as the
tires lose traction and the ESC system becomes active. If the light begins to flash
during acceleration, ease up on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to the prevailing road conditions.
The light also flashes when TCS is active. To improve the vehicle's traction when
starting off in deep snow, sand or gravel, it may be desirable to switch the ESC
system to Partial Off mode by momentarily pressing the ESC Off
below the climate controls, on the switch panel.
- Charging System Light
• This light shows the status of the electrical charging system. If the charging
system light remains on, it means that the vehicle is experiencing a problem with
the charging system.
• We recommend you do not continue driving if the charging system light is on. Have
the vehicle serviced immediately.
- Oil Pressure Warning Light
• This light indicates low engine oil pressure. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound for four
minutes when this light turns on.
• We recommend you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
• This light monitors the Anti-Lock Brake System (ABS).
• If the light is not on during starting, stays on, or turns on while driving, we
recommend you drive to the nearest service center and have the vehicle serviced
immediately.
- Electronic Throttle Control (ETC) Light
• This light informs you of a problem with the Electronic Throttle Control (ETC)
system.
