system parts. Make sure that the parking
brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and parking on a
hill, see Driving Characteristics and Towing
Tips 0280.
Automatic EPB Release
The EPB automatically releases if the vehicle
is running, placed into gear, and an attempt
is made to drive. Avoid rapid acceleration
when the EPB is applied to preserve parking
brake lining life.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brake
pedal pulsation, and/or pedal movement
during this time may occur. Continue to
apply the brake pedal as the driving
situation dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
(Continued)
Warning (Continued)
driving may result in injury, death,
or vehicle damage. SeeDefensive Driving
0 205.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) prevents the vehicle from
rolling in an unintended direction during the
transition from brake pedal release to
accelerator pedal apply. The brakes release
when the accelerator pedal is applied. If the
accelerator pedal is not applied within a few
minutes, the Electric Parking Brake will
apply. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.

238 Driving and Operating
If the vehicle has a diesel engine, exhaust
braking is automatically activated when
Tow/Haul Mode is selected. It maintains
vehicle speed by automatically
implementing a shift pattern that uses the
engine and the transmission to slow the
vehicle. The system will command
downshifts and use the turbo charger on the
engine to reduce vehicle speed when the
brake is applied. The normal Tow/Haul shift
pattern will return once the vehicle is on a
low grade or when the accelerator pedal is
pressed.
For more information, seeTowing
Equipment 0287 or
Towing the Vehicle 0376.If equipped, select Terrain Mode by
pressing the
gbelow the 4mtransfer
case button.
gTerrain Mode : Use this mode when
traveling on very rough roads at very low
speeds, such as a two-track or heavily rutted
road. This mode can also be used for pulling
a boat out of the water on a trailer. When
in Terrain Mode, the vehicle shifts
automatically, but will hold a lower gear
longer to maximize engine torque. This
mode has a unique pedal map and
transmission shift pattern for better control
at lower speeds and over rough terrain. This
mode modifies accelerator pedal mapping,
transmission shift pattern, ride height, and
electronic Limited Slip Differential (eLSD).
When the vehicle comes to a stop on an
upward grade, automatic vehicle hold is
engaged until the driver presses the
accelerator pedal. Stop/Start and cruise
control are disabled in Terrain Mode. Active Braking during lift throttle will be
engaged. This feature automatically applies
light braking to simulate heavy engine
braking of four-wheel-dive low. It also
applies light braking in D (Drive) until the
vehicle is at idle speeds. In L1 and L2 light
braking will typically bring the vehicle to a
stop. Active Braking during lift throttle also
reduces trailer braking.
Terrain Mode automatically exits to Normal
Mode if the brake temperatures become too
hot, electronic parking brake becomes
inoperable, or the vehicle cannot perform
braking or vehicle hold.
