Service Electric Parking Brake Light0116.
There are also parking brake-related Driver
Information Center (DIC) messages.
Before leaving the vehicle, check the red EPB
status light to ensure that the EPB is
applied.
If a message displays on the DIC indicating
the transmission is unable to shift soon, the
service electric parking brake is on, and the
EPB light flashes at the same time, the
system must be reset. Start the vehicle,
apply the EPB, and then release it. The
message and the light should turn off. See
Electric Parking Brake Light 0116 and
Service Electric Parking Brake Light 0116.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch.
The red EPB status light will flash and then
stay on once the EPB is fully applied. If the
red EPB status light flashes continuously,
then the EPB is only partially applied or
there is a problem with the EPB. A DIC
message will display. Release the EPB and
try to apply it again. If the light does not come on, or keeps flashing, have the vehicle
serviced. Do not drive the vehicle if the red
EPB light is flashing. See your dealer.
If the amber service EPB warning light is on,
press the EPB switch. Continue to hold the
switch until the red EPB status light remains
on. If the amber service EPB warning light is
on, see your dealer.
If the EPB is applied while the vehicle is
moving, the vehicle will decelerate as long
as the switch is pressed. If the switch is
pressed until the vehicle comes to a stop,
the EPB will remain applied.
The vehicle may automatically apply the EPB
in some situations when the vehicle is not
moving. This is normal, and is done to
periodically check the correct operation of
the EPB system, or as required by other
safety functions that utilize the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:
1. Turn the ignition on or to accessory mode.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily. The EPB is released when the red EPB status
light is off.
If the amber service EPB warning light is on,
release the EPB by pressing and holding the
EPB switch. Continue to hold the switch
until the red EPB status light is off. If either
light stays on after release is attempted, see
your dealer.
Caution
Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake
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 0288.
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.

This feature is not intended for use when
the vehicle is stuck in sand, mud, ice, snow,
or gravel. If the vehicle becomes stuck, seeIf
the Vehicle Is Stuck 0204.
7Off-Road Mode : Use this mode for
off-road recreational driving. Off-Road Mode
should be used to improve driving at
moderate speeds, on grass, gravel, dirt,
unpaved roads, or snow-covered roads. The
accelerator pedal is tuned for off-road use.
This mode modifies pedal mapping, ride
height, and Traction Control System (TCS)
performance. For more information on
off-road driving, see Off-Road Driving0198.
_Tow/Haul Mode : Use this mode
when hauling heavy loads to provide
increased performance and vehicle control.
Tow/Haul Mode adjusts the transmission
shift pattern, steering, and Electronic
Stability Control (ESC) performance.
If the vehicle is turned off while in Tow/
Haul Mode and then restarted within four
hours or less, it will remain active.
Otherwise, the vehicle will start in
Normal Mode. 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, see
Towing
Equipment 0296 orTransporting a Disabled
Vehicle 0386.
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.

230 Driving and Operating
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.
