appear in the instrument cluster display
Ú page 91.
If the “SERVICE STOP/START SYSTEM” message
appears in the instrument cluster display, have the
system checked by an authorized dealer.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL — IF EQUIPPED
When engaged, the Cruise Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h).
The Cruise Control buttons are located on the right
side of the steering wheel.
Cruise Control Buttons

1 — On/Off
2 — CANC/Cancel
3 — SET (+)/Accel
4 — RES/Resume
5 — SET (-)/Decel
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.

To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, pushing the CANC button,
or normal brake pressure while slowing the vehicle
will deactivate the Cruise Control system without
erasing the set speed from memory.
The following conditions will also deactivate the
Cruise Control without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Pushing the on/off button or placing the ignition in
the OFF position will erase the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC) —
I
F EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently Ú page 119.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your Cruise Control. ACC
utilizes a radar sensor and a forward facing
camera designed to detect a vehicle directly ahead
of you.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or acceleration (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the mode selected
Ú page 327.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead; and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance condi -
tions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.

To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) button or
SET (-) button, the new set speed will be the current
speed of the vehicle.
When ACC Is Active:
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system applies the brake down to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
your vehicle will release the brakes two seconds
after coming to a full stop.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting appears in the instrument cluster display.

Distance Settings

1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

VEHICLE LOADING
CERTIFICATION LABEL
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side door or
pillar.
This label contains the month and year of
manufacture, Gross Vehicle Weight Rating
(GVWR), front and rear Gross Axle Weight Rating
(GAWR), and Vehicle Identification Number (VIN). A
Month-Day-Hour (MDH) number is included on this
label and indicates the Month, Day and Hour of
manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your
vehicle including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear (GAWR).
Total load must be limited so GVWR and front and
rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable
load weight a truck can carry, including the weight
of the driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the
front and rear axles. The load must be distributed
in the cargo area so that the GAWR of each axle is
not exceeded.
Each axle GAWR is determined by the components
in the system with the lowest load carrying capacity
(axle, springs, tires or wheels). Heavier axles or
suspension components sometimes specified by
purchasers for increased durability does not
necessarily increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire
size listed.
Inflation Pressure
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full GAWR.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the “Malfunc -
tion Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

21_WD_OM_EN_USC_t.book Page 141

STARTING AND OPERATING143
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do not
exceed either front or rear GAWR Ú page 141.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch
ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied
by the maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle.
These kinds of hitches are commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and
the trailer axle(s). When used in accordance with
the manufacturer's directions, it provides for a
more level ride, offering more consistent steering and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway
control also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer Sway Control
(TSC) and a weight distributing (load equalizing)
hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on
vehicle and trailer configuration/loading to comply
with Gross Axle Weight Rating (GAWR)
requirements.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the vehicle
and have a collision.WARNING!
An improperly adjusted weight-distributing
hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight-distributing hitch systems may not be
compatible with surge brake couplers. Consult
with your hitch and trailer manufacturer or a
reputable Recreational Vehicle dealer for
additional information.

TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your bumper or trailer hitch.

Weight Distribution
Consider the following items when computing the
weight on the rear axle of the vehicle:The tongue weight of the trailer.
The weight of any other type of cargo or equip
-
ment put in or on your vehicle.
The weight of the driver and all passengers.
NOTE:
Remember that everything put into or on the trailer
adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options
must be considered as part of the total load on
your vehicle. Refer to the Tire And Loading Infor -
mation placard for the maximum combined weight
of occupants and cargo for your vehicle
Ú page 300.
TOWING REQUIREMENTS
To promote proper break-in of the new vehicle
drivetrain components, the following guidelines
are recommended. Perform the maintenance listed in Scheduled
Servicing Ú
page 264. When towing a trailer,
never exceed the GAWR or GCWR ratings.
CAUTION!
Always load a trailer with 60% of the weight in
the front of the trailer. This places 10% of the
GTW on the tow hitch of your vehicle. Loads
balanced over the wheels or heavier in the rear
can cause the trailer to sway severely side to
side which will cause loss of control of the
vehicle and trailer. Failure to load trailers heavier
in front is the cause of many trailer collisions.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The engine, axle or other parts could be
damaged.
Then, during the first 500 miles (805 km) that
a trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have a collision.
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure
or tires.
CAUTION!

152STARTING AND OPERATING
TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission
Select the DRIVE (D) 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 to manually
select a lower gear.
If equipped with Tow N Go, it is recommended
to place the vehicle in tow mode by pushing the
TOW button.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions, will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
This action will also provide better engine braking.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate perfor -
mance and avoids frequent downshifts. For
example, 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.
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),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.

DRIVING TIPS
ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance and a
narrower track to make them capable of
performing in a wide variety of off-road
applications. Specific design characteristics give
them a higher center of gravity than conventional
passenger cars.
An advantage of the higher ground clearance is a
better view of the road, allowing you to anticipate
problems. They are not designed for cornering at
the same speeds as conventional passenger cars
any more than sports cars are designed to perform
satisfactorily in off-road conditions. Avoid sharp
turns or abrupt maneuvers. As with other vehicles
of this type, failure to operate this vehicle correctly
may result in loss of control or vehicle rollover.
