When you are in a severe braking condition involving
the use of the ABS, you will experience some pedal drop
as the vehicle comes to a stop. This is the result of the
system reverting to the base brake system.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal and indicate that the
system is functioning properly.
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
continuousbraking pressure during the stopping se-
quence (do not “pump” the brakes). Do not reduce
brake pedal pressure unless braking is no longer de-
sired. Once the brake pedal is released, the BAS is
deactivated.
WARNING!
• The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions.
•
The BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
• The capabilities of a BAS-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)
The Traction Control System (TCS) 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), func-
tions 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
204 STARTING AND OPERATING
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 the Partial Off mode or Full Off
mode. Refer to “Electronic Stability Control (ESC)” in
this section for further information.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will
maintain the level of brake pressure the driver applied
for a short period of time after the driver takes his foot
off the brake pedal. If the driver does not apply the
throttle during this short period of time, the system will
release brake pressure and the vehicle will roll down
the hill. The system will release brake pressure in
proportion to the amount of throttle applied as the
vehicle starts to move in the intended direction of
travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped. •
Vehicle must be on a 2.5% (manual transmission) or
7% grade or greater (automatic transmission) grade
hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle in NEUTRAL [manual transmission], vehicle
facing uphill is in forward gear; vehicle backing
uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer, when the
system will not activate and slight rolling may
occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be
done using the Customer Programmable Features in the
Uconnect Settings. Refer to “Uconnect Settings” in for
further information.

Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) system enhances
directional control and stability of the vehicle under
various driving conditions. ESC corrects for oversteer-
ing or understeering of the vehicle by applying the
brake of the appropriate wheel to assist in counteracting
the oversteering or understeering condition. Engine
power may also be reduced to help the vehicle maintain
the desired path. ESC uses sensors in the vehicle to
determine the vehicle path intended by the driver and
compares it to the actual path of the vehicle. When the
actual path does not match the intended path, ESC
applies the brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESC Off Switch (Automatic Transmission)
ESC Off Switch (Manual Transmission)
206 STARTING AND OPERATING
NOTE:The ESC Off switch is located left of the steering
column (Manual Transmission Only).
WARNING!
• The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from acting on
the vehicle, nor can it increase the traction af-
forded by prevailing road conditions. ESC cannot
prevent all accidents, including those resulting
from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC also can-
not prevent collisions resulting from loss of ve-
hicle control due to inappropriate driver input for
the conditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of
an ESC equipped vehicle must never be exploited
in a reckless or dangerous manner which could
jeopardize the user ’s safety or the safety of others.
• Vehicle modifications, or failure to properly
maintain your vehicle, may change the handling
characteristics of your vehicle, and may nega-
tively affect the performance of the ESC system.
(Continued)
WARNING! (Continued)
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion or poor vehicle maintenance that reduces the
effectiveness of the ESC system can increase the
risk of loss of vehicle control, vehicle rollover,
personal injury and death.
ESC Operating Modes
The ESC system has three available operating modes.
Full On
This is the normal operating mode for ESC. Whenever
the vehicle is started, the ESC system will be in On
mode. This mode should be used for most driving
situations. ESC should only be turned to Partial Off for
specific reasons as noted below.
5
STARTING AND OPERATING 207
Partial Off
This mode is entered by momentarily pressing the ESC
Off switch. This mode is intended for times when a
more spirited driving experience is desired. It is also
intended for driving in deep snow, sand or gravel
conditions, when more wheel spin than ESC would
normally allow is required to gain traction.
To turn ESC on again, momentarily press the switch
again. This will restore the normal ESC On mode of
operation.
WARNING!
When in “Partial Off” mode, the TCS functionality
of ESC (except for the limited slip feature described
in the TCS section) has been disabled and the “ESC
Off Indicator Light” will be illuminated. When in
“Partial Off” mode, the engine power reduction of
TCS is disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.Full Off
This mode is intended for off-highway or off-road use
only and should not be used on public roadways. In this
mode, all TCS and ESC stability features are turned
OFF, except for the limited slip feature described in the
TCS section. To enter the “Full Off” mode, depress and
hold the ESC OFF switch for five seconds. After five
seconds, the ESC OFF Indicator Light will illuminate,
and the “ESC OFF” message will display in the instru-
ment cluster. To turn ESC ON again, momentarily press
the ESC OFF switch.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are cancelled.
Therefore, the enhanced vehicle stability offered by
ESC is unavailable. The “Full Off” ESC mode is
intended for off-highway or offroad use only.
