When you override the system,
the green indicator light
illuminates and the lead vehicle
graphic does not show in the
information display.
The system will resume operation when
you release the accelerator pedal. The
vehicle speed will decrease to the set
speed, or a lower speed if following a
slower vehicle.
Changing the Set Speed • Accelerate or brake to the desired
speed, 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.
189Cruise 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.

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. ActionCause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.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 conditions
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 conditions
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 normal cruise
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.
You can manually change from adaptive
cruise control to normal cruise control
through the information display. E71340
The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting will not display, the system will not
automatically respond to lead vehicles and
automatic braking will activate. The
system defaults to adaptive cruise control
when you start the vehicle.
ECO Cruise Control This feature saves vehicle energy by
relaxing acceleration compared to
standard cruise control. For example, your
vehicle may temporarily lose speed when
going uphill. ECO will appear in the
information display when you activate ECO
cruise control. It can be switched on or off
in the information display. See General
Information (page 86).
191Cruise Control
If your vehicle loses electrical power while
you are driving (or if the ignition is turned
off), you can steer the vehicle manually,
but it takes more effort. Extreme
continuous steering may increase the effort
it takes for you to steer. This occurs to
prevent internal overheating and
permanent damage to your steering
system. If this should occur, you will neither
lose the ability to steer the vehicle
manually nor will it cause permanent
damage. Typical steering and driving
maneuvers will allow the system to cool
and steering assist will return to normal.
Steering Tips
If the steering wanders or pulls, check for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.
Adaptive Learning
The EPS system adaptive learning helps
correct for road irregularities and improves
overall handling and steering feel. It
communicates with the vehicle's brake
system to help operate advanced stability
control and accident avoidance systems.
Additionally, whenever the battery is
disconnected or a new battery installed,
the vehicle must be driven a short distance
before the strategy is relearned and all
systems are reactivated. 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
202Driving Aids
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.
The warning system sensitivity can be
adjusted to one of three possible settings
by using the information display control.
See General Information (page 86).
Note: If the system cannot be turned off in
a vehicle equipped with MyKey®, See
Principle of Operation (page 50). Note: If collision warnings are perceived as
being too frequent or disturbing then the
warning sensitivity can be reduced, though
the manufacturer recommends using the
highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings. See General
Information (page 86).
Blocked Sensors E145632
If a message regarding a blocked sensor
appears in the information display, the
radar signals from the sensor have been
obstructed. The sensors are located behind
a fascia cover near the driver side of the
lower grille. When the sensors are
obstructed, a vehicle ahead cannot be
detected and the collision warning system
does not function. The following table lists
possible causes and actions for this
message being displayed.

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).
•
If the front end of the vehicle is hit or
damaged, the radar sensing zone may be
altered causing missed or false collision
warnings. See your authorized dealer to
have your collision warning radar checked
for proper coverage and operation.

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.
210Load Carrying
E142667
When driving through water, traction or
brake capability may be limited. Also,
water may enter your engine’s air intake
and severely damage your engine or your
vehicle may stall.
Once through the water, always dry the
brakes by moving your vehicle slowly while
applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as
quickly as dry brakes.
FLOOR MATS E142666 WARNINGS
Always use floor mats that are
designed to fit the foot well of your
vehicle. Only use floor mats that
leave the pedal area unobstructed. Only
use floor mats that are firmly secured to
retention posts so that they cannot slip out
of position and interfere with the pedals
or impair safe operation of your vehicle in
other ways.
Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury.
Always make sure that the floor
mats are properly attached to the
retention posts in the carpet that are
supplied with your vehicle. Floor mats must
be properly secured to both retention posts
to ensure mats do not shift out of position.
Never place floor mats or any other
covering in the vehicle foot well that
cannot be properly secured to
prevent them from moving and interfering
with the pedals or the ability to control the
vehicle.
Never place floor mats or any other
covering on top of already installed
floor mats. Floor mats should always
rest on top of vehicle carpeting surface and
not another floor mat or other covering.
Additional floor mats or any other covering
will reduce the pedal clearance and
potentially interfere with pedal operation.
Check attachment of floor mats on
a regular basis. Always properly
reinstall and secure floor mats that
have been removed for cleaning or
replacement.
Always make sure that objects
cannot fall into the driver foot well
while the vehicle is moving. Objects
that are loose can become trapped under
the pedals causing a loss of vehicle control.
