•Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
• Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc-
tion.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:
• If the “ACC/FCW Unavailable Wipe Front Radar Sen-
sor” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at your
authorized dealer.
• Installing a snow plow, front-end protector, an aftermar-
ket grille or modifying the grille is not recommended.
Doing so may block the sensor and inhibit ACC/FCW
operation.Service ACC/FCW Warning
If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/
FCW Unavailable Service Required”, there may be an
internal system fault or a temporary malfunction that
limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpectedly.
The driver needs to stay alert and may need to intervene.
Towing A Trailer
Towing a trailer is not advised when using ACC.
234 STARTING AND OPERATING

Offset Driving
ACC may not detect a vehicle in the same lane that is offset
from your direct line of travel, or a vehicle merging in from
a side lane. There may not be sufficient distance to the
vehicle ahead. The offset vehicle may move in and out of
the line of travel, which can cause your vehicle to brake or
accelerate unexpectedly.
Turns And Bends
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for stabil-
ity reasons, with no target vehicle detected. Once the
vehicle is out of the curve the system will resume your
original set speed. This is a part of normal ACC system
functionality.
NOTE:On tight turns ACC performance may be limited.

Using ACC On Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.
Lane Changing
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and it
may not detect the vehicle until it’s too late for the ACC
system to take action. ACC may not detect a vehicle until it
is completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be attentive
and ready to apply the brakes if necessary.

236 STARTING AND OPERATING

Narrow Vehicles
Some narrow vehicles traveling near the outer edges of the
lane or edging into the lane are not detected until they have
moved fully into the lane. There may not be sufficient
distance to the vehicle ahead.
Stationary Objects And Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and the
vehicle ahead is stopped in your lane. Always be attentive
and ready to apply the brakes if necessary.

the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect on
the way your vehicle steers and handles and the way the
brakes operate.
NOTE:Refer to the “Vehicle Certification Label” affixed to
the rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
TRAILER TOWING
In this section, you will find safety tips and information on
limits to the type of towing you can reasonably do with
your vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning vehicles
used for trailer towing.
Manual Transmission — If Equipped
Trailer towing with this vehicle is not recommended.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle. This
includes driver, passengers, cargo and tongue weight. The
total load must be limited so that you do not exceed the
GVWR. Refer to “Vehicle Loading/Vehicle Certification La-
bel” in “Starting And Operating” for further information.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables, and equipment (permanent or tempo-
rary) loaded in or on the trailer in its loaded and ready for
operation condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight of
the trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle
and trailer when weighed in combination.
6
STARTING AND OPERATING 253

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. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting And Operating” for further infor-
mation.
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.
Tongue Weight (TW)
The tongue weight 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
The trailer sway control 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 Trailer Sway Control (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 the most popular on the market today and they
are commonly used to tow small and medium sized
trailers.
254 STARTING AND OPERATING

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 addi-
tion 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 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!
•An improperly adjusted Weight Distributing Hitch
system may reduce handling, stability, braking per-
formance, and could result in a collision.
• Weight Distributing 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.
