STARTING AND OPERATING 119
Automatic Transmission
Select the DRIVE range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control (if equipped) to
manually select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
u n
der heavy loading conditions will improve perfor -
mance and extend transmission life by reducing
e x

cessive shifting and heat buildup. This action will
also provide better engine braking.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
d i
sengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.
AutoStick — If Equipped
When using the AutoStick shift control, select
the highest gear that allows for adequate perfor -
mance and avoids frequent downshifts. For
e x

ample, choose “5” if the desired speed can be
maintained. Choose “4” or “3” if needed to
maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce vehicle
speed as necessary to avoid extended driving at
high RPM. Return to a higher gear or vehicle
speed when grade and road conditions allow.
RECREATIONAL TOWING (BEHIND
MOTORHOME)
Recreational towing (with all four wheels on the
ground, or using a tow dolly) is NOT ALLOWED. The
only acceptable method for towing this vehicle
(behind another vehicle) is on a vehicle trailer with
all four wheels OFF the ground.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
Information in this section will aid in safe
controlled launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or other
slippery surfaces may cause the driving wheels to
pull erratically to the right or left. This phenomenon
occurs when there is a difference in the surface
traction under the rear (driving) wheels.
Traction
When driving on wet or slushy roads, it is possible
for a wedge of water to build up between the tire
and road surface. This is known as hydroplaning
and may cause partial or complete loss of vehicle
control and stopping ability. To reduce this
possibility, the following precautions should be
observed:
Slow down during rainstorms or when the roads
are slushy.
Slow down if the road has standing water or
puddles.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
WARNING!
Rapid acceleration on slippery surfaces is
dangerous. Unequal traction can cause sudden
pulling of the front wheels. You could lose
control of the vehicle and possibly have a
collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).

120 STARTING AND OPERATING
(Continued)
Replace tires when tread wear indicators first
become visible.
Keep tires properly inflated.
Maintain sufficient distance between your
vehicle and the vehicle in front of you to avoid a
collision in a sudden stop.
Your vehicle may be equipped with a Limited Slip
D i

fferential (LSD) that reduces, but does not
eliminate, the amount of wheel slip across a given
axle for improved handling.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
Flowing/Rising Water Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following
Warnings and Cautions before doing so.
WARNING!
Do not drive on or across a road or path where
water is flowing and/or rising (as in storm
run-off). Flowing water can wear away the road
or path's surface and cause your vehicle to sink
into deeper water. Furthermore, flowing and/or
rising water can carry your vehicle away swiftly.
Failure to follow this warning may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not exceed
5
mph (8 km/h) when driving through
st

anding water.
Driving through standing water limits your
vehicle’s braking capabilities, which increases
stopping distances. Therefore, after driving
through standing water, drive slowly and
lightly press on the brake pedal several times
to dry the brakes.
Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
CAUTION!
Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom
of the tire rims mounted on the vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when driving
th
rough standing water. This will minimize
wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
( i

.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is milky
or foamy in appearance) after driving through
standing water. Do not continue to operate
the vehicle if any fluid appears contaminated,
as this may result in further damage. Such
damage is not covered by the New Vehicle
Limited Warranty.
Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause
serious internal damage to the engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
CAUTION!

SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and
brake performance under most braking conditions.
The system automatically prevents wheel lock and
enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that
th

e ABS is working properly each time the vehicle
is started and driven. During this self-check, you
may hear a slight clicking sound as well as some
related motor noises.
The ABS is activated during braking when the
s y

stem detects one or more wheels are beginning
to lock. Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic stops
may increase the likelihood of ABS activation(s).
You also may experience the following normal
c h

aracteristics when the ABS activates:
ABS motor noise or clicking sounds (you may
continue to hear for a short time after the stop).
Brake pedal pulsations.
A slight drop of the brake pedal at the end of the
stop. The ABS is designed to function with the Original
E
q

uipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may
stay on for as long as four seconds.
If the ABS Warning Light remains on or comes on
w h

ile driving, it indicates that the Anti-Lock portion
of the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally if
the Anti-Lock Brake Warning Light is on.
If the ABS Warning Light is on, the brake system
s h

ould be serviced as soon as possible to restore
the benefits of Anti-Lock Brakes. If the Anti-Lock
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to interfer -
ence caused by improperly installed or high
out
put radio transmitting equipment. This
interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by qual -
ified professionals.
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer.
Just press firmly on your brake pedal when you
need to slow down or stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro -
planing.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize the
user’s safety or the safety of others.

138 SAFETY
Brake Warning Light does not come on when the
ignition is placed in the ON/RUN mode, have the
light repaired as soon as possible.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Electronic Brake Force
Distribution (EBD), Electronic Roll Mitigation
(ERM), Electronic Stability Control (ESC), Hill Start
Assist (HSA), and Traction Control System (TCS).
These systems work together to enhance both
vehicle stability and control in various driving
conditions.
Your vehicle may also be equipped with Rain Brake
S u

pport (RBS) and Ready Alert Braking (RAB).
Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.
If the Brake System Warning Light remains on or
com

es on while driving, it indicates that the brake
system is not functioning properly and that
immediate service is required. If the Brake System
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
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 sensing 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
continuous braking pressure during the stopping
sequence (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released,
the BAS is deactivated.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking
torque between the front and rear axles by limiting
braking pressure to the rear axle. This is done to
prevent overslip of the rear wheels to avoid vehicle
instability, and to prevent the rear axle from
entering the Anti-Lock Brake System (ABS) before
the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel angle
and vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen
the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during
severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, striking
objects or other vehicles.
NOTE:
ERM is disabled any time the ESC is in “Full Off”
m od
e (if equipped). See Ú page 139 in this
section for a complete explanation of the available
E S
C modes.
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. 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.
