very slippery surfaces, or hydroplaning. The capa-
bilities of an ABS-equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability.
A feature of the TCS system, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will allow more engine torque to be applied to the wheel
that is not spinning. This feature remains active even if
TCS and ESC are in either the “Partial Off” or “Full Off”
modes. Refer to “Electronic Stability Control (ESC)” in
this section for further information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer5
STARTING AND OPERATING 463

When in ESC Off mode, ESC and TCS, except for the
Brake Limited Differential (BLD) feature described in the
TCS section, are turned off until the vehicle reaches a
speed of 40 mph (64 km/h). For speeds at or exceeding
40 mph (64 km/h) the ESC goes into partial off. When the
vehicle speed drops below 35 mph (56 km/h), the ESCsystem goes back to off. To turn ESC on again, momen-
tarily press the ESC OFF switch. This will restore normal
“ESC On” mode of operation. The
ESC Off Indicator
Light” will always be illuminated when ESC is off and
partial off.

transfer case (if equipped) is shifted from 4H range or
NEUTRAL to 4L range, the ESC system will be in this
mode. In 4L range, ESC and TCS, except for the Brake
Limited Differential (BLD) feature described in the TCS
section, are turned off until the vehicle reaches a speed of
40 mph (64 km/h). For speeds at or exceeding 40 mph
(64 km/h) the ESC goes into partial off. When the vehicle
speed drops below 35 mph (56 km/h), the ESC system
shuts off. The ESC is off at low vehicle speeds in 4L range
so that it will not interfere with off-road driving, but the
ESC function returns to provide the stability feature at
speeds above 40 mph (64 km/h). The “ESC OFF Indicator
Light” will always be illuminated in 4L range when ESC
is off.NOTE:
The “ESC OFF” message will display and the
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.
