4WD Low Range Set Speeds
• 1st = 1 mph (1.6 km/h)
• 2nd = 2.5 mph (4 km/h)
• 3rd = 4 mph (6 km/h)
• 4th = 5.5 mph (9 km/h)

• PARK = HDC will not function
HDC is intended for low speed off-road driv-
ing only. At vehicle speeds above 20 mph
(32 km/h), HDC will no longer function. When
the vehicle speed drops below 20 mph
(32 km/h), HDC function will automatically re-
sume and the vehicle speed will return to the
chosen set speed.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to the
driving conditions and is responsible for main-
taining a safe vehicle speed.
ESC Activation/Malfunction Indicator
Light and ESC OFF Indicator Light
The "ESC Activation/Malfunction
Indicator Light" in the instrument
cluster will come on when the igni-
tion switch is turned to the ON
position. It should turn off with the
engine running. 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), see your authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
The "ESC Activation/Malfunction Indicator
Light" (located in the instrument cluster) starts
to flash as soon as the tires lose traction and
the ESC system becomes active. The "ESC
Activation/Malfunction Indicator Light" also
flashes when TCS is active. If the "ESC
Activation/Malfunction Indicator Light" begins
to flash during acceleration, ease up on the
accelerator and apply as little throttle as pos-
sible. Be sure to adapt your speed and driving
to the prevailing road conditions.
NOTE:
• The "ESC Activation/Malfunction Indica-
tor Light" and the "ESC OFF Indicator
Light" come on momentarily each time
the ignition switch is turned ON.
• Each time the ignition is turned ON, the
ESC system will be ON even if it was
turned off previously.
• The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
