26. Electronic Stability Program (ESP) Indicator Light /
Traction Control System (TCS) Indicator Light
If the Electronic Stability Program (ESP) /
Traction Control System (TCS) Indicator Light
begins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. This indicator light starts to flash as soon as the
tires lose traction and the Electronic Stability Program
(ESP) becomes active. The ESP/TCS Indicator Light also
flashes when TCS is active. Be sure to adapt your speed
and driving to the prevailing road conditions. If the
ESP/TCS Indicator Light is on solid, the ESP system has
been turned off by the driver or a temporary condition
exists that will not allow full ESP function.
27. O/D (Overdrive) Off Indicator Light
This light will illuminate when the O/D OFF
button has been selected and overdrive has been
turned off. The O/D OFF button is located on the center
console.
28. Sway Bar Indicator Light — If Equipped
This indicator will illuminate when the front
sway bar is disconnected.
29. Electronic Stability Program (ESP) / Brake Assist
System (BAS) Warning Light
The Electronic Stability Program (ESP) / Brake
Assist System (BAS) warning light in the in-
strument cluster comes on when the ignition
switch is turned to the ON position. The light
should go out with the engine running. If the ESP/BAS
warning light comes on continuously with the engine
running, a malfunction has been detected in either the
ESP or the BAS system. If this light stays illuminated,
have the ESP and BAS checked at an authorized dealer as
soon as possible. Refer to “Electronic Brake Control
System” in Section 5 for more information.
