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
driving may result in injury, death,
or vehicle damage. SeeDefensive Driving
0 151.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) temporarily 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 or automatically release after a few
seconds. 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.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control System
(TCS) and Electronic Stability Control (ESC).
These systems help limit wheel spin and
assist the driver in maintaining control,
especially on slippery road conditions.
TCS activates if it senses any of the drive
wheels are spinning or beginning to lose
traction. When this happens, TCS applies the
brakes to the spinning wheels and reduces
vehicle power to limit wheel spin.
The TCS and ESC calibrations are different
while in Off Road, Terrain, or Baja mode,
if equipped. They provide optimum
performance in various off-road
environments.
ESC activates when the vehicle senses a
difference between the intended path and
the direction the vehicle is actually traveling.
ESC selectively applies braking pressure to
one or more of the vehicle wheel brakes to
assist the driver in keeping the vehicle on
the intended path. Trailer Sway Control (TSC) is also on automatically when the
vehicle is started. See
Trailer Sway Control
(TSC) 0242.
If using cruise control and ESC begins
limiting wheel spin, cruise control will
automatically disengage. You can turn cruise
control back on when road conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See If the
Vehicle Is Stuck 0161 and “Turning the
Systems Off and On” later in this section.

Hill Descent Control (HDC)
If equipped, HDC can be used when driving
downhill. It sets and maintains vehicle speed
while descending a very steep incline in a
forward or reverse gear.
To activate HDC, in the controls app on the
infotainment home screen, select Controls >
Drive & Park > Hill Descent Control.
Press ON or OFF to enable or disable HDC.
Vehicle speed must be below 60 km/h
(37 mph).
The HDC light displays on the instrument
cluster when enabled.
HDC can maintain vehicle speeds between
4 and 30 km/h (3 and 19 mph) on an incline
greater than or equal to a 10% grade. A blinking HDC light indicates that the
system is actively applying the brakes to
maintain vehicle speed.
Set speed is established as soon as you
enable HDC. Apply the accelerator to
increase, or the brake pedal to decrease, the
set speed.
Smaller HDC speed control adjustments are
accomplished using the cruise up or down
buttons. Each tap of the +RES will increase
the set speed by 0.8 km/h (0.5 mph), while
each tap of the SET–
will decrease the set
speed by 0.8 km/h (0.5 mph). This adjusted
speed becomes the new set speed.
HDC will remain enabled between 30 and
60 km/h (19 and 37 mph); however, vehicle
speed cannot be set or maintained in this
range. It will automatically disable if the
vehicle speed is above 80 km/h (50 mph) or
above 60 km/h (37 mph) for at least
30 seconds.

192 Driving and Operating
Caution
If you try to lock the axle while the
vehicle is stuck and the tires are spinning,
the vehicle’s drivetrain could be damaged.
The repairs would not be covered by the
vehicle warranty. Always lock the axle
before attempting situations and/or
navigating terrain that could cause the
vehicle to become stuck.
Caution
If the vehicle’s axle is locked while driving
on pavement, the drivetrain could be
damaged. Repairs would not be covered
by the vehicle warranty. Do not use the
locking axle on pavement.
Before the front axle can be locked, the rear
axle must be locked and the transfer case
must be in 4
n.
To lock the rear axle: 1. Press the rear axle locking switch with the vehicle moving less than 30 km/h
(20 mph).
2. Wait for the light in the switch to stop flashing and remain illuminated to show
that the rear axle is locked.
If the electronic locking differential has
difficulty engaging, release the
accelerator pedal.
The locking rear axle will be disengaged
when the vehicle speed exceeds 30 km/h
(20 mph). The Off-Road Mode allows the
axle lock to remain engaged at higher
vehicle speeds. After pressing the switch to unlock the axle,
it may remain locked due to torque in the
driveline. The axle is more easily unlocked
by turning the steering wheel to the right
and to the left while traveling at a low
speed.
Locking Front Axle
If equipped, the locking front axle can give
the vehicle additional traction when
traveling in off-road situations such as mud,
snow, steep hills, and uneven terrain.
The locking front axle must not be used on
high traction surfaces such as pavement.
