Changing the Set Speed
• Accelerate or brake to the desiredspeed, then press and release
SET+.
• Press and hold SET+ or SET- until the desired set speed shows on the
information display. The vehicle
speed will gradually change to the
selected speed.
• Press and release SET+ or SET-. The set speed will change in
approximately 1 mph (2 km/h)
increments.
The system may apply the brakes to
slow the vehicle to the new set speed.
The set speed will display
continuously in the information
display while the system is active.
Resuming the Set Speed
Note: Only use resume if you are
aware of the set speed and intend to
return to it.
Press and release RES. The vehicle
will return to the previously set speed.
The set speed will display
continuously in the information
display while the system is active.
Low Speed Automatic
Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An
audible alarm will sound and the
automatic braking releases if the
vehicle drops below this speed.
Hilly Condition Usage
Note: An audible alarm will sound and
the system will shut down if it is
applying brakes for an extended period
of time. This allows the brakes to cool
down. The system will function
normally again when the brakes have
cooled down.
You should select a lower gear
position when the system is active in
situations such as prolonged downhill
driving on steep grades, for example
in mountainous areas. The system
needs additional engine braking in
these situations to reduce the load on
the vehicle’s regular brake system to
prevent them from overheating.
Switching the System Off
Note: The set speed memory erases
when you switch off the system.
Press and release OFF or turn off the
ignition.
Detection Issues
The radar sensor has a limited field of
vision. It may not detect vehicles at all
or detect a vehicle later than expected
in some situations. The lead vehicle
graphic will not illuminate if the
system does not detect a vehicle in
front of you.

Cruise Control

E71621
Detection issues can occur:When driving on a different
line than the vehicle in front.
A
With vehicles that edge into
your lane. The system can
only detect these vehicles
once they move fully into
your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming
out of a bend or curve in the
road.
C
In these cases the system may brake
late or unexpectedly. The driver
should stay alert and intervene when
necessary. If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This
could cause missed or false vehicle
detections. See an authorized dealer
to have the radar checked for proper
coverage
and operation.
System Not Available
Conditions that can cause the system
to deactivate or prevent the system
from activating when requested
include:
• a blocked sensor
• high brake temperature
• a failure in the system or a related
system.
Blocked Sensor
WARNINGS
Do not use the system when
towing a trailer with brake
controls. Aftermarket trailer brakes
will not function properly when the
system is activated because the
brakes are electronically controlled.
Failing to do so may result in loss of
vehicle control, which could result in
serious injury.
Do not use tire sizes other than
those recommended because
this can affect the normal operation
of the system. Failing to do so may
result in a loss of vehicle control,
which could result in serious injury.

E145632
A message displays if something
obstructs the radar signals from the
sensor. The sensor is located behind
a fascia cover near the driver side of
the lower grille. The system cannot
detect a vehicle ahead and will not
function when something obstructs
the radar signals. The following table
lists possible causes and actions for
this message displaying.
Action
Cause
Clean the grille surface in front of the
radar or remove the object causing the obstruction.
The surface of the radar in the grille is
dirty or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that it is no longer obstructed.
The surface of the radar in the grille is
clean but the message remains in the display.
Do not use the system in these condi-tions because it may not detect any vehicles ahead.
Heavy rain or snow is interfering with
the radar signals.
Do not use the system in these condi-tions because it may not detect any vehicles ahead.
Swirling water, or snow or ice on the
surface of the road may interfere with the radar signals.
Wait a short time or switch to normalcruise control.
You are in a desert or remote area with
no other vehicles and no roadside objects.
Due to the nature of radar technology,
it is possible to get a blockage warning
and not be blocked. This can happen,
for example, when driving in sparse
rural or desert environments. A false
blocked condition will either self clear
or clear after a key cycle.
Switching to Normal Cruise
Control
WARNING
Normal cruise control will not
brake due to slower vehicles.
Always be aware of which mode is
selected and apply the brakes when
necessary.

COLLISION WARNING
SYSTEM
PRINCIPLE OF OPERATION (If
Equipped)
WARNINGS
This system is designed to be a
supplementary driving aid. It is
not intended to replace the driver’s
attention, and judgment, or the need
to apply the brakes. This system does
NOT activate the brakes
automatically. Failure to press the
brake pedal to activate the brakes
may result in a collision.
The collision warning system
with brake support cannot help
prevent all collisions. Do not rely on
this system to replace driver judgment
and the need to maintain distance
and speed.
Note: The system does not detect,
warn or respond to potential collisions
with vehicles to the rear or sides of the
vehicle.
Note: The collision warning system is
active at speeds above approximately
5 mph (8 km/h).
E156130
This system is designed to alert the
driver of certain collision risks. A radar
detects if your vehicle is rapidly
approaching another vehicle traveling
in the same direction as yours.
E156131
If it is, a red warning light illuminates
and an audible warning chime sounds.
The brake support system assists the
driver in reducing the collision speed
by charging the brakes. If the risk of
collision further increases after the
warning light illuminates, the brake
support prepares the brake system
for rapid braking. This may be
apparent to the driver. The system
does not automatically activate the
brakes but, if the brake pedal is
pressed, full force braking is applied
even if the brake pedal is lightly
pressed.
Using the Collision Warning
System
WARNING
The collision warning system’s
brake support can only help
reduce the speed at which a collision
occurs if the driver applies the
vehicle’s brakes. The brake pedal
must be pressed just like any typical
braking situation.

System Limitations
WARNING
The collision warning system’s
brake support can only help
reduce the speed at which a collision
occurs if the driver applies the
vehicle’s brakes. The brake pedal
must be pressed just like any typical
braking situation.
Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision
warning. These include: • Stationary vehicles or vehicles
moving below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane.
• Severe weather conditions (see blocked sensor section).
• Debris build-up on the grille near the headlamps (see blocked
sensor section).
• Small distance to vehicle ahead.
• Steering wheel and pedal movements are large (very active
driving style).

for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.The
Gross Combined Weight must
never exceed the Gross
Combined Weight Rating.
Maximum Loaded Trailer
Weight - is the highest possible
weight of a fully loaded trailer the
vehicle can tow. It assumes a
vehicle with mandatory options,
driver and front passenger weight
(150 pounds [68 kilograms]
each), no cargo weight (internal
or external) and a tongue load of
10–15% (conventional trailer) or
king pin weight of 15–25% (fifth
wheel trailer). Consult an
authorized dealer (or the RV and
Trailer Towing Guide available at
an authorized dealer) for more
detailed information.
Tongue Load or Fifth Wheel
King Pin Weight - refers to the
amount of the weight that a trailer
pushes down on a trailer hitch. Examples: For a 5000 pound
(2268 kilogram) conventional
trailer, multiply 5000 by 0.10 and
0.15 to obtain a proper tongue
load range of 500 to 750 pounds
(227 to 340 kilograms). For an
11500 pound (5216 kilogram) fifth
wheel trailer, multiply by 0.15 and
0.25 to obtain a proper king pin
load range of 1725 to 2875 pounds
(782 to 1304 kilograms).
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
Safety Compliance Certification
Label.
Do not use replacement tires
with lower load carrying
capacities than the original tires
because they may lower the
vehicle’s GVWR and GAWR
limitations. Replacement tires
with a higher limit than the original
tires do not increase the GVWR
and GAWR limitations.
Exceeding any vehicle weight
rating limitation could result
in serious damage to the vehicle
and/or personal injury.
Steps for determining the
correct load limit:
1. Locate the statement "The combined weight of occupants
and cargo should never exceed
XXX kg or XXX lb." on your
vehicle’s placard.

Load Carrying

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label.
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of your vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury.
Note: There may be electrical
items such as fuses or relays that
can affect trailer towing operation.
See Fuses (page 255).
Weight, not volume designates
your vehicle's load capacity. You
cannot necessarily use all
available space when loading a
vehicle.
Towing a trailer places an
additional load on your vehicle's
engine, transmission, axle, brakes,
tires and suspension. Inspect
these components periodically
during, and after, any towing
operation. Load Placement
To help minimize how trailer
movement affects the vehicle
when driving:
• Load the heaviest items closest
to the trailer floor.
• Load the heaviest items in the center of the left and right side
trailer tires.
• Load the heaviest items above the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a tow bar with the correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward the
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in the Load Carrying
chapter. See Load Limit (page
224). You can also find the
information in the RV & Trailer
Towing Guide, available at an
authorized dealer.

RECOMMENDED TOWING
WEIGHTS
Note:Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
below.
Note: Be sure to take into
consideration trailer frontal area.
Do not exceed 20 feet
2 (1.86
meters2).
Note: For high altitude operation,
reduce the gross combined weight
by 2% per 1000 feet (300 meters)
starting at the 1000 foot (300
meter) elevation point. Note:
Certain states require
electric trailer brakes for trailers
over a specified weight. Be sure to
check state regulations for this
specified weight. The maximum
trailer weights listed may be limited
to this specified weight, as the
vehicle’s electrical system may not
include the wiring connector
needed to activate electric trailer
brakes.
Your vehicle may tow a Class I
trailer provided the maximum
trailer weight is less than or equal
to the maximum trailer weight
listed for your vehicle
configuration on the following
charts.

ESSENTIAL TOWING
CHECKS
Follow these guidelines for safe
towing:
• Do not tow a trailer until you driveyour vehicle at least 1000 miles
(1600 kilometers).
• Consult your local motor vehicle laws for towing a trailer.
• See the instructions included with towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if you tow a trailer. See
your scheduled maintenance
information.
• If you use a rental trailer, follow the instructions the rental agency gives
you.
You can find information on load
specification terms found on the tire
label and Safety Compliance label as
well as instructions on calculating
your vehicle's load in the Load
Carrying chapter. See Load Limit
(page 224).
Remember to account for the trailer
tongue weight as part of your vehicle
load when calculating the total
vehicle weight.
Hitches
Do not use a hitch that either clamps
onto the bumper or attaches to the
axle. Distribute the trailer load so 10-15%
of the total trailer weight is on the
tongue.
Safety Chains
Note:
Never attach safety chains to
the bumper.
Always connect the safety chains to
the hook retainers of your vehicle
hitch.
To connect the safety chains, cross
them under the trailer tongue and
allow enough slack for turning tight
corners. Do not allow the chains to
drag on the ground.
Trailer Brakes
WARNING
Do not connect a trailer's
hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase.
Electric brakes and manual,
automatic or surge-type trailer brakes
are safe if you install them properly
and adjust them to the
manufacturer's specifications. The
trailer brakes must meet local and
federal regulations.
The rating for the tow vehicle's
braking system operation is at the
gross vehicle weight rating, not the
gross combined weight rating.
234
Towing

Trailer Lamps
WARNING
Never connect any trailer lamp
wiring to the vehicle's tail lamp
wiring; this may damage the electrical
system resulting in fire. Contact your
authorized dealer as soon as possible
for assistance in proper trailer tow
wiring installation. Additional
electrical equipment may be required.
Trailer lamps are required on most
towed vehicles. Make sure all running
lights, brake lights, turn signals and
hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing
up to get the feel of your
vehicle-trailer combination before
starting on a trip. When turning, make
wider turns so the trailer wheels clear
curbs and other obstacles.
When Towing a Trailer
• Do not drive faster than 70 mph (113 km/h) during the first 500
miles (800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections and trailer wheel lug
nuts thoroughly after you have
traveled 50 miles (80 kilometers).
• When stopped in congested or heavy traffic during hot weather,
place the gearshift in position P to
aid engine and transmission
cooling and to help A/C
performance. • Turn off the speed control with
heavy loads or in hilly terrain. The
speed control may turn off
automatically when you are towing
on long, steep grades.
• Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as
they may overheat and become
less effective.
• If your transmission is equipped with a Grade Assist or Tow/Haul
feature, use this feature when
towing. This provides engine
braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade:
• Turn the steering wheel to pointyour vehicle tires away from
traffic flow.
• Set your vehicle parking brake.
• Place the automatic transmission in position P.
• Place wheel chocks in front and back of the trailer wheels.
(Chocks not included with
vehicle.)
Launching or Retrieving a Boat
or Personal Watercraft (PWC)
Note: Disconnect the wiring to the
trailer before backing the trailer into
the water.
