OFF-ROAD DRIVING TIPS
When To Use 4WD Low — If Equipped
When off-road driving, shift to 4WD Low for
additional traction. This range should be limited to
extreme situations such as deep snow, mud, or
sand where additional low speed pulling power is
needed. Vehicle speeds in excess of 25 mph
(40 km/h) should be avoided when in 4WD Low.
Driving Through Water
Although your vehicle is capable of driving through
water, there are a number of precautions that
must be considered before entering the water. Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
If you must drive through water, try to determine
the depth and the bottom condition (and location
of any obstacles) prior to entering. Proceed with
caution and maintain a steady controlled speed
less than 5 mph (8 km/h) in deep water to
minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm
run-off), avoid crossing until the water level
recedes and/or the flow rate is reduced. If you
must cross flowing water avoid depths in excess of
9 inches (23 cm). The flowing water can erode the
streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting. Standing Water
Avoid driving in standing water deeper than
20 inches (51 cm), and reduce speed
appropriately to minimize wave effects. Maximum
speed in 20 inches (51 cm) of water is less than
5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil,
transmission oil, axle, transfer case) to ensure the
fluids have not been contaminated. Contaminated
fluid (milky, foamy in appearance) should be
flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to AWD Low if necessary Ú
page 112. Only
shift into a lower gear to maintain forward motion.
Over-revving the engine can spin the wheels and
traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
.
WARNING!
Do not drive in 4WD Low on dry pavement;
driveline damage may result. 4WD Low locks
front and rear drivelines together and does not
allow for differential action between the front to
rear driveshafts. Driving in 4WD Low on
pavement will cause driveline binding; use only
on wet or slippery surfaces.
CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering as a precaution, and check all
fluids afterward. Driving through water may
cause damage not covered by the New Vehicle
Limited Warranty.

Disabling And Enabling HSA
This feature can be turned on or turned off.
To change the current setting see Ú page 159.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. It will periodically apply a small amount
of brake pressure to remove any water buildup on
the front brake rotors. It functions when the
windshield wipers are in LO or HI speed. When Rain
Brake Support is active, there is no notification to
the driver and no driver interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full
braking during emergency braking situations. It
anticipates when an emergency braking situation
may occur by monitoring how fast the throttle is
released by the driver. The Electronic Brake
Controller (EBC) will prepare the brake system for
a panic stop.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of
each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce engine power to
provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD)
functions similarly 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 power
to be applied to the wheel that is not spinning.
BLD may remain enabled even if TCS and ESC are
in reduced modes.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement. It
is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there
may not be enough brake pressure to hold
both the vehicle and the trailer on a hill when
the brake pedal is released. In order to avoid
rolling down an incline while resuming accel -
eration, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.
HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle.
Also, be certain to place the transmission
in PARK.
Failure to follow these warnings can result in a
collision or serious personal injury.
