Antilock Brake System (ABS)
Illuminates when the ABS is not available or when the ABS is malfunctioning. Since the ABS system

Esc - Electronic Stability Control
At vehicle ignition, the ESC telltale lamp illuminates for approximately 3 seconds and then turns off. If
it remains on steadily (not flashing) after ignition, or if it illuminates steadily while you are driving, the
ESC system may not be fully functional or their operation may be completely disabled. If this happens,
your vehicle will still have normal service braking and can still be driven, but without the benefits of the
ESC system.
Flashes quickly when ESC intervenes to reduce risk of loss of control.
High Beam
Illuminates when the high beams are selected. High and low beams are selected with the multi-
function lever. Refer to
"ANTILOCK BRAKING SYSTEM (ABS)" on page 27
