(Continued)
The following conditions will also deactivate the
Speed 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
ADAPTIVE CRUISE CONTROL (ACC) — IF
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. Speed
Control function performs differently. Please
refer to the proper section within this chapter.
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 sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accelerate
(not to exceed the original set speed) auto
-
matically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.
The Cruise Control system has two control
modes:
Adaptive Cruise Control mode for main -
taining an appropriate distance between
vehicles.
Normal (Fixed Speed) Cruise Control mode
for cruising at a constant preset speed. For
additional information, refer to “Normal
(Fixed Speed) Cruise Control Mode” in this
section.
NOTE:
Normal (Fixed Speed) Cruise Control will not
react to preceding vehicles. Always be aware of
the mode selected. You can change the mode by using the Cruise
Control buttons. The two control modes
function differently. Always confirm which mode
is selected.
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 opera -
tion 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 and death or serious personal
injury.

2. Open the fuel filler door.

Fuel Filler

NOTE:
In certain cold conditions, ice may prevent
the fuel door from opening. If this occurs,
lightly push on the fuel door to break the ice
buildup and re-release the fuel door using the
inside release button. Do not pry on the door.
There is no fuel filler cap. A flapper door
inside the pipe seals the system.
3. Insert the fuel nozzle fully into the filler pipe – the nozzle opens and holds the flapper
door while refueling. NOTE:
Only the correct size nozzle opens the latches
allowing the flapper door to open.
4. Fill the vehicle with fuel – when the fuel
nozzle “clicks” or shuts off the fuel tank is
full.
5. Wait five seconds before removing the fuel nozzle to allow fuel to drain from nozzle.
6. Remove the fuel nozzle and close the fuel door.
Emergency Gas Can Refueling
NOTE:
Most gas cans will not open the flapper door.
A funnel is provided to open the flapper door
to allow emergency refueling with a gas can.

1. Retrieve funnel from the spare tire storage area.

2. Insert funnel into same filler pipe opening as the fuel nozzle. 3. Ensure funnel is inserted fully to hold
flapper door open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire
storage area.
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
“Malfunction 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.

Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and
equipment (permanent or temporary) 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.
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 Certification Label” in
this chapter for further information.
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.WARNING!
If the gross trailer weight is 5,000 lbs
(2,267 kg) or more, it is recommended to use
a weight-distributing hitch to ensure stable
handling of your vehicle. If you use a standard
weight-carrying hitch, you could lose control
of your vehicle and cause a collision.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.

NOTE:
The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight referenced
on the Tire and Loading Information placard. Refer to “Tires” in “Servicing And Maintenance” for further information. The addition of passengers and
cargo may require reducing trailer tongue load and Gross Trailer Weight (GTW). Redistributing cargo (to the trailer) may be necessary to avoid
exceeding Rear Gross Axle Weight Rating (GAWR) of 3,900 lbs (1,769 kg).
Vehicles not factory equipped with trailer tow package are limited to 3,500 lbs (350 lbs tongue weight).

(Continued)
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
equipment 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 Information”
placard for the maximum combined weight of
occupants and cargo for your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of the new vehicle
drivetrain components, the following guidelines
are recommended.
Perform the maintenance listed in the
“Scheduled Servicing”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance” for
the proper maintenance intervals. 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 colli -
sion.
When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over -
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspension,
chassis structure or tires.
Safety chains must always be used
between your vehicle and trailer. Always
connect the chains to the hook retainers of
the vehicle hitch. Cross the chains under
the trailer tongue and allow enough slack
for turning corners.
