● the 4WD switch must be in the 4H position
and the vehicle speed must be under 21
mph (35 km/h), and
● the hill descent control system switch must
be ON.
The hill descent control indicator light will come
on when the system is activated. Also, the
stop/tail lights illuminate while the hill descent
control system applies the brakes to control ve-
hicle speed.
If the accelerator or brake pedal is depressed
while the hill descent control system is on, the
system will stop operating temporarily. As soon
as the accelerator or brake pedal is released, the
hill descent control system begins to function
again if the hill descent control operating condi-
tions are fulfilled.
The hill descent control indicator light blinks if the
switch is on and all conditions for system activa-
tion are not met or if the system becomes disen-
gaged for any reason.
To turn off the hill descent control system, push
the switch to the OFF position.
For additional information, see “Hill descent con-
trol system on indicator light” earlier in this sec-
tion and “Hill descent control system” in the
“Starting and driving” section of this manual.
The Electronic Locking Rear Differential (E-Lock)
system can help provide added traction if the
vehicle is stuck or becoming stuck.
To activate the E-Lock system:
● the 4WD switch must be in the 4LO position
(4-wheel drive vehicles),
● the vehicle must be stopped or moving at 4
mph (7 km/h) or less, and
● the E-Lock system switch must be turned
ON.
When the E-Lock switch is turned ON, the indi-
cator light will flash until the system engages.
However, if all operation conditions listed above
are not met or the system becomes disengaged,
the indicator light will continue to flash.
The Anti-Lock Brake (ABS) system is disabled
and the ABS light illuminates when the E-Lock
system is ON. Also, the Vehicle Dynamic Control
(VDC) system is disabled and the VDC light
illuminates when the E-Lock system is ON.
See “Electronic locking rear differential (E-Lock)
system” in the “Starting and Driving” section for
further explanation and system limitations.
WARNING
● Never leave the E-Lock system ON
when driving on paved or hard-surfaced
roads. Turning the vehicle may result in
the rear wheels slipping and result in an
accident and personal injury. After us-
ing the E-Lock system to free the ve-
hicle, turn the system OFF.
