HDC is intended for low speed off-road driving only.
At vehicle speeds above 30 mph (48 km/h), HDC will no
longer function. When the vehicle speed drops below
30 mph (48 km/h), HDC function will automatically
resume and the vehicle speed will return to the chosen set
speed.

ling vehicle speed when descending hills. The driver

is responsible for maintaining a safe vehicle speed.
ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator light for the ESP is
combined with the BAS indicator. The “ESP/
BAS Warning Light” and the “ESP/TCS Indi-
cator Light” in the instrument cluster both
come on when the ignition switch is turned to the ON
position. They should both go out with the engine
running.
If the “ESP/BAS Warning Light” comes on
continuously with the engine running, a mal-
function has been detected in either the ESP or
the BAS system, or both. If this light remains on
after several ignition switch cycles, and the vehicle has
been driven several miles at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon as possible
to have the problem diagnosed and corrected.
