SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust system each
time the vehicle is raised for lubrication or oil
change. Replace as required.
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, people riding in these
areas are more likely to be seriously
injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing (CO), follow
these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift-
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.

If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force
outside air into the vehicle. Set the
blower at high speed.

To increase the distance setting, push the
Distance Setting — Increase button and
release. Each time the button is pushed, the
distance setting increases by one bar
(longer).
To decrease the distance setting, push the
Distance Setting — Decrease button and
release. Each time the button is pushed, the
distance setting decreases by one bar
(shorter).
PARKSENSE REAR PARK
ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system
provides visual and audible indications of
the distance between the rear fascia and a
detected obstacle when backing up (e.g.
during a parking maneuver). Refer to “Park-
Sense System Usage Precautions” in this
section for limitations of this system and
recommendations.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the ON/
RUN position. ParkSense can be active only when the gear
selector is in REVERSE. If ParkSense is
enabled at this gear selector position, the
system will remain active until the vehicle
speed is increased to approximately 7 mph
(11 km/h) or above. When in REVERSE and
above the system's operating speed, a
warning will appear within the instrument
cluster display indicating the vehicle speed
is too fast. The system will become active
again if the vehicle speed is decreased to
speeds less than approximately 6 mph
(9 km/h).
ParkSense Sensors
The four ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors’ field of
view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction,
depending on the location, type and orienta
-
tion of the obstacle.
Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch, located on the switch
panel below the climate controls.
ParkSense Switch
When the ParkSense switch is pushed to
disable the system, the instrument cluster
display will show the “PARKSENSE OFF”
message for approximately five seconds.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” in
your Owner’s Manual for further information.
When the gear selector is moved to
REVERSE and the system is disabled, the
instrument cluster display will show the
“PARKSENSE OFF” message for as long as
the vehicle is in REVERSE (Not in 4L).

on the instrument panel below the climate
controls.Push the switch to turn on the
Hazard Warning flasher. When the
switch is activated, all directional turn signals will flash on and off to warn
oncoming traffic of an emergency. Push the
switch a second time to turn off the Hazard
Warning flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled
and it is creating a safety hazard for other
motorists. When you must leave the vehicle to seek
assistance, the Hazard Warning flashers will
continue to operate even though the ignition
is placed in the OFF position.
NOTE:
With extended use the Hazard Warning
flashers may wear down your battery.

FUEL CONSUMPTION AND
CO
2 EMISSIONS

The fuel consumption and CO2 emission
figures declared by the manufacturer are deter -
mined on the basis of the type-approval tests
laid down by the applicable standards in the
country where the vehicle is registered.

The type of route, traffic conditions, weather
conditions, driving style, general condition of
the vehicle, trim level/equipment/ accesso -
ries, use of the climate control system,
vehicle load, presence of roof racks and other
situations that adversely affect the aerody -
namics or wind resistance lead to different
fuel consumption values than those
measured. The fuel consumption will only become more
regular after driving the first 1,864 miles
(3,000 km).
To find the specific fuel consumption and
CO
2 emission figures for this vehicle, please
refer to the data in the Certificate of Confor -
mity (if equipped), and the related documen -
tation that accompanies the vehicle (if
equipped).

The button located in the center of the
left-hand control will make the radio switch
between various modes available (AM/FM/
DAB, etc.).
Media Mode
Pushing the top of the switch once goes to
the next track on the selected media (AUX/
USB/Bluetooth®). Pushing the bottom of the
switch once goes to the beginning of the
current track or to the beginning of the
previous track if it is within eight seconds
after the current track begins to play.
AUX/USB/MP3 CONTROL
The Media Hub is located on the instrument
panel, below the climate controls. Behind
the media hub access door, the Media Hub
contains one AUX port, a Type C USB Port
and one standard USB Port. Both USB Ports
allow you to play music from MP3 players /
smartphones or USB devices through the
vehicle’s sound system.
The Smart Charging USB ports provide
power to your device up to an hour after the
vehicle is turned off.
NOTE:
Two devices can be plugged in at the same
time and both ports will provide charging
capabilities. Only one port can transfer
data to the system at a time. A pop-up will
appear and allow you to select the device
transferring data.
Both ports share a single data connection.
The user cannot switch between Type A or
Type C. For example, if a device is plugged into the
Type A USB port and another device is
plugged into the Type C USB port, a message
will appear and allow you to select which
device to use.
