permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal also lists engine displacement.
Please consult your warranty information for complete emission warranty
information.
On-board Diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle.When the service engine soon indicator illuminates, the OBD-II
system has detected a malfunction. Temporary malfunctions
may cause the service engine soon indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel fill inlet may not have been properly closed. See Easy Fuel®
No Cap Fuel System in this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly closing the fuel fill inlet or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon indicator
should stay off the next time the engine is started. A driving cycle
consists of a cold engine start-up followed by mixed city or highway
driving. No additional vehicle service is required.
If the service engine soon indicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the service engine soon indicator on can result in
increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and can lead to more costly repairs.

Anti-Lock Brake System
This system helps you maintain steering control during emergency stops
by keeping the brakes from locking.This lamp momentarily illuminates when you turn the ignition
on. If the light does not illuminate during start-up, remains on
or flashes, the anti-lock brake system may be disabled and may
need to be serviced.
If the anti-lock brake system is disabled, normal braking is still
effective. If the brake warning lamp illuminates with the parking
brake released, have your brake system serviced immediately.
HINTS ON DRIVING WITH ANTI-LOCK BRAKES
When the system is operating, the brake pedal will pulse and may travel
further. Maintain pressure on the brake pedal. You may also hear a noise
from the system. This is normal.
The anti-lock braking system will not eliminate the risks when:
• You drive too closely to the vehicle in front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
PARKING BRAKE
WARNING: If the parking brake is fully released, but the brake
warning lamp remains illuminated, then driving your vehicle
could result in reduced braking ability, increased stopping distances and
potential loss of brakes. See your authorized dealer as soon as possible.
WARNING: Always set the parking brake fully and make sure
that the transmission is securely latched in park (P). Failure to
set the parking brake and engage park could result in vehicle roll-away,
property damage or bodily injury.
To set the parking brake, press the parking brake pedal down to its
fullest extent.
To release the parking brake, press the parking brake pedal down again.

SENSING SYSTEM (IF EQUIPPED)
WARNING:To help avoid personal injury, please read and
understand the limitations of the system as contained in this
section. Sensing is only an aid for some (generally large and fixed)
objects when moving in reverse on a flat surface at parking speeds.
Traffic control systems, inclement weather, air brakes, and external
motors and fans may also affect the function of the sensing system; this
may include reduced performance or a false activation.
WARNING: To help avoid personal injury, always use caution
when in R (Reverse) and when using the sensing system.
WARNING: This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller objects,
particularly those close to the ground.
WARNING: Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the normal
detection zone of the system, may create false beeps.
Note: Keep the sensors (located on the bumper/fascia) free from snow,
ice and large accumulations of dirt. If the sensors are covered, the
system’s accuracy can be affected. Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to the bumper/fascia, leaving it
misaligned or bent, the sensing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
The sensing system warns the driver of obstacles within a certain range
of the bumper area. The system turns on automatically whenever the
ignition is switched on.
When receiving a detection warning, the radio volume is reduced to a
predetermined level. After the warning goes away, the radio volume
returns to the previous level.
The system can be turned off using the information display control.
Refer to the Information Display chapter.

If a fault is present in the system, a warning message appears in the
information display and does not allow the driver to switch the faulted
system on.
Note:If your vehicle is equipped with MyKey®, it is possible to prevent
turning the sensing system off. Refer to the MyKey®chapter.
Using the Rear Sensing System
The rear sensors are only active when the transmission is in R.Asthe
vehicle moves closer to the obstacle, the rate of the audible warning
increases. When the obstacle is fewer than 12 inches (30 centimeters)
away, the warning sounds continuously. If a stationary or receding object
is detected farther than 12 inches (30 centimeters) from the side of the
vehicle, the tone sounds for only three seconds. Once the system detects
an object approaching, the warning sounds again.
A. Coverage area of up to 6 feet
(2 meters) from the rear bumper
(with a decreased coverage area at
the outer corners of the bumper).
The system detects certain objects while the transmission is in R:
• and moving toward a stationary object at a speed of 3 mph (5 km/h)
or less.
• but not moving, and a moving object is approaching the rear of the
vehicle at a speed of 3 mph (5 km/h) or less.
• and moving at a speed of less than 3 mph (5 km/h) and a moving
object is approaching the rear of the vehicle at a speed of less than
3 mph (5 km/h).

ACTIVE PARK ASSIST (IF EQUIPPED)
WARNING:This system is designed to be a supplementary park
aid. It may not work in all conditions and is not intended to
replace the driver’s attention and judgment. The driver is responsible
for avoiding hazards and maintaining a safe distance and speed, even
when the system is in use.
Note: The driver is always responsible for controlling the vehicle,
supervising the system and intervening if required.
The system detects an available parallel parking space and automatically
steers the vehicle into the space (hands-free) while you control the
accelerator, gearshift and brakes. The system visually and/or audibly
instructs the driver to park the vehicle.
The system may not function correctly if something passes between the
front bumper and the parking space (i.e. a pedestrian or cyclist) or if the
edge of the neighboring parked vehicle is high from the ground (i.e. a
bus, tow truck or flatbed truck).
Note: The sensors may not detect objects in heavy rain or other
conditions that cause disruptive reflections.
Note: The sensors may not detect objects with surfaces that absorb
ultrasonic waves.
Note: After a tire change the system will go through a relearning
procedure. During this time the system performance may deteriorate.
The system should not be used if:
• a foreign object (i.e. bike rack or trailer) is attached to the front or
rear of the vehicle or at another location close to the sensors.
• an overhanging object (i.e. surfboard) is attached to the roof.
• the front bumper or side sensors are damaged (i.e. in a collision) or
obstructed by a foreign object (i.e. front bumper cover).
• a mini-spare tire is in use.

Troubleshooting the System
The system does not look for a space
The traction control system may be off
Any door (except the driver’s) may not be completely closed
The system does not offer a particular space
Something may be contacting the front bumper or side sensors
There is not enough room on both sides of the vehicle in order to park
There is not enough space for the parking maneuver on the opposite
side of the parking space
The vehicle is farther than 5 ft (1.5 m) from the parking space
The vehicle is closer than 16 in. (40 cm) from neighboring parked
vehicles
The transmission is in R (Reverse); the vehicle must be moving
forward to detect a parking space
The vehicle is going faster than 20 mph (35 km/h)
The system does not position the vehicle where I want in the space
The vehicle is rolling in the opposite direction of the transmission (i.e.
rolling forward when R [Reverse] is selected)
The transmission is in R (Reverse); the vehicle must be moving forward to
detect a parking space
An irregular curb along the parking space prevents the system from
aligning the vehicle properly
Vehicles or objects bordering the space may not be positioned correctly
The vehicle was pulled too far past the parking space. The system
performs best when you drive the same distance past the parking space
The tires may not be installed or maintained correctly (i.e. not inflated
correctly, improper size, or of different sizes)
A repair or alteration has changed detection capabilities
A parked vehicle has a high attachment (i.e. salt sprayer, snowplow,
moving truck bed, etc.)
The parking space length or position of parked objects changed after your
vehicle passed
The temperature around your vehicle changes quickly (i.e. driving from a
heated garage into the cold, or after leaving a car wash)

REAR VIEW CAMERA SYSTEM
WARNING:The rear view camera system is a reverse aid
supplement device that still requires the driver to use it in
conjunction with the interior and exterior mirrors for maximum
coverage.
WARNING: Objects that are close to either corner of the
bumper or under the bumper, might not be seen on the screen
due to the limited coverage of the camera system.
WARNING: Back up as slow as possible since higher speeds
might limit your reaction time to stop the vehicle.
WARNING: Use caution when using the rear video camera and
the trunk is ajar. If the trunk is ajar, the camera will be out of
position and the video image may be incorrect. All guidelines have been
removed when the trunk is ajar.
WARNING: Use caution when turning camera features on or off
while in R (Reverse). Make sure the vehicle is not moving.
The rear view camera system provides a video image of the area behind
the vehicle.
During operation, lines appear in the display which represent your
vehicle’s path and proximity to objects behind the vehicle. The camera is located on the trunk
under the badge.

Guidelines and the Centerline
Note:Fixed guidelines and active guidelines (if equipped) are only
available when the transmission is in R (Reverse).
A. Active guidelines (if equipped)
B. Centerline
C. Fixed guideline: Green zone
D. Fixed guideline: Yellow zone
E. Fixed guideline: Red zone
F. Rear bumper
If your vehicle is equipped with active guidelines they are only shown
with fixed guidelines. To use active guidelines, turn the steering wheel to
point the guidelines toward an intended path. If the steering wheel
position is changed while reversing, the vehicle might deviate from the
original intended path.
The fixed and active guidelines fade in and out depending on the
steering wheel position. When the steering wheel position is straight, the
active guidelines are not shown.
Always use caution while reversing. Objects in the red zone are closest
to your vehicle and objects in the green zone are further away. Objects
are getting closer to your vehicle as they move from the green zone to
the yellow or red zones. Use the side view mirrors and rear view mirror
to get better coverage on both sides and rear of the vehicle.
