Message
A malfunction is preventing the adaptive cruise from engaging.
Adaptive Cruise Malfunction
Front Sensor Not Aligned Contact an authorized dealer to have the radar checked for proper coverage and operation. Conditions exist preventing the system from being available.
Adaptive Cruise Not Available
You have a blocked radar because of poor radar visibility due to inclement weather or ic\
e, mud,or water in front of the radar. You can typically clean the sensor to resolve this.
Adaptive Cruise Not Available Sensor
Blocked See Manual Due to the nature of radar technology, it is possible to get a blockage warning with no actual
block. This happens, for example, when driving in sparse rural or desert environments. A false blocked condition either self clears, or clears after you restart your vehicl\
e.
You have selected normal cruise control. The system does not brake or react to traffic.
Normal Cruise Active Adaptive Braking Off
Displays when the adaptive cruise control is going to cancel and you mus\
t take control.
Adaptive Cruise - Driver Resume Control
Displays when the vehicle speed is too slow to activate the adaptive cru\
ise control and there isno lead vehicle in range.

Note:
Brake support and automatic
emergency braking are active at speeds up
to 75 mph (120 km/h). If the vehicle has a
radar sensor included with adaptive cruise
control, then brake support and automatic
emergency braking are active up to the
maximum speed of the vehicle.
Pedestrian Detection Limitations
Pedestrian detection is active at speeds up
to
50 mph (80 km/h).
Pedestrian detection functions optimally
when detected hazards are clearly
identifiable. System performance may reduce
in situations where pedestrians are running,
partly obscured, have a complex
background, or cannot be distinguished from
a group. LOCATING THE PRE-COLLISION
ASSIST SENSORS
Camera.
1
Radar sensor (if equipped).
2
If a message regarding a blocked sensor or
camera appears in the information display,
something is obstructing the radar signals or
camera images. The radar sensor is behind
the fascia cover in the center of the lower
grille. With a blocked sensor or camera, the
system may not function, or performance
may reduce.
See Pre-Collision Assist –
Information Messages (page 285). Note:
Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
could change. This could cause missed or
false vehicle detections. Have your vehicle
serviced to have the radar checked for
proper coverage and operation.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message could display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor recalibrates successfully.

If you disconnect or replace the battery and
your vehicle has an automatic transmission,
it must relearn its adaptive strategy. Because
of this, the transmission may shift firmly when
first driven. This is normal operation while
the transmission fully updates its operation
to optimum shift feel.
Remove and Reinstall the Battery
To disconnect or remove the battery, do the
following:
1. Apply the parking brake and switch the
ignition off.
2. Switch all electrical equipment off, for example lights and radio.
3. Wait a minimum of two minutes before disconnecting the battery.
Note: The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty. 4. Disconnect the negative battery cable
terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal procedure.
Note: Before reconnecting the battery, make
sure the ignition remains switched off.

If you disconnect or replace the vehicle
battery, you must reset the following
features:
• Window bounce-back. See Windows
(page 130).
• Clock Settings.
• Pre-set radio stations.
• Steering Angle Sensor. Note:
To calibrate the steering angle sensor,
drive the vehicle above
30 mph (50 km/h)
for a minimum of 1.2 mi (2 km). Make sure to
drive straight ahead for a minimum of 30
seconds. Several vehicle functions are
disabled and a warning light could appear
until the sensor is calibrated.
Battery Management System
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery drain
is detected, the system temporarily disables
some of the following features:

Cleaning Wheels
Only use a recommended wheel and tire
cleaner to clean the wheels weekly. For
additional information and assistance, we
recommend that you contact an authorized
dealer.
1.
Use a sponge to remove heavy deposits
of dirt and brake dust.
2. Rinse well after cleaning.
Note: Do not apply a cleaning chemical to
warm or hot wheel rims and covers.
If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before parking your vehicle.
This reduces the risk of corrosion of the
brake discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note: Some car washes could damage
wheel rims and covers.
Note: Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers. Cleaning the Engine Compartment
Use a vacuum cleaner to remove debris from
the screen area below windshield.
Note:
If you are not familiar with the parts
around the engine do not wash the engine
compartment. Avoid frequent engine
washes.
When washing the engine compartment:
• Never wash or rinse the engine while it
is hot or running.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well.
• Cover the battery, power distribution box,
and air filter assembly to prevent water
damage.
Note: If your vehicle has an engine cover
remove the cover before application of
shampoo and degreaser.
• Spray an approved engine shampoo and
degreaser on all parts that require
cleaning and rinse with water. Cleaning Stripes or Graphics
It is recommended to wash your vehicle by
hand however, pressure washing may be
used under the following conditions:
•
Use a spray with a 40° wide spray angle
pattern.
• Keep the nozzle at a 12 in (305 mm)
distance and 90° angle to your vehicle's
surface.
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than 179°F (82°C).
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
Cleaning Camera Lenses and Sensors
We recommend that you only use lukewarm
or cold water and a soft cloth to clean the
camera lens and sensors.
Note: Do not pressure wash camera lens
and sensors.

CHANGING A FLAT TIRE
WARNING: If the tire pressure
monitor sensor becomes damaged it may
not function.
Note: The use of tire sealant may damage
your tire pressure monitoring system and
should only be used in roadside
emergencies. If you must use a sealant, use
the Tire Mobility Kit sealant. Replace the tire
pressure monitoring system sensor and
valve stem on the wheel by an authorized
dealer after use of the sealant.
Note: The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
If you get a flat tire while driving, do not apply
the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe place
on the side of the road. Have a flat serviced by an authorized dealer
in order to prevent damage to the tire
pressure monitoring system sensors.
See
Tire Pressure Monitoring System Overview
(page 385). Replace the spare tire with a road
tire as soon as possible. During repairing or
replacing of the flat tire, have an authorized
dealer inspect the tire pressure monitoring
system sensor for damage.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased risk
of loss of vehicle control, injury or death.
If you have a dissimilar spare wheel and tire,
then it is intended for temporary use only.
This means that if you need to use it, you
should replace it as soon as possible with a
road wheel and tire assembly that is the
same size and type as the road tires and
wheels that were originally provided on your
vehicle. If the dissimilar spare tire or wheel
is damaged, replace it instead of repairing
it. A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire assembly
that is different in brand, size or appearance
from the road tires and wheels and can be
one of three types:
1.
T-type mini-spare: This spare tire begins
with the letter T for tire size and may have
Temporary Use Only molded in the sidewall.
2.
Full-size dissimilar spare with label on
wheel: This spare tire has a label on the
wheel that states: THIS WHEEL AND TIRE
ASSEMBLY FOR TEMPORARY USE ONLY.
When driving with one of the dissimilar spare
tires listed above, do not:
• Exceed
50 mph (80 km/h).
• Load the vehicle beyond maximum
vehicle load rating listed on the Safety
Compliance Label.
• Tow a trailer.
• Use snow chains on the end of the
vehicle with the dissimilar spare tire.
• Use more than one dissimilar spare tire
at a time.
