ENVIRONMENTAL PROTECTION
SYSTEMS — IF EQUIPPED

Gasoline Particulate Filter (GPF) — 2.0L T4
Petrol Versions Only
The Gasoline Particulate Filter is a mechan-
ical filter, integral to the exhaust system,
which physically traps carbon particles present in the exhaust gases of 2.0L T4
petrol engines.
The particulate filter is needed to eliminate
almost all carbon particle emissions in
compliance with current/future regulations
and standards.
Since this filter physically traps particulates,
it must be cleaned (regenerated) during
normal driving operation to remove carbon
particles. The regeneration procedure is
controlled automatically by the engine
control unit according to the filter conditions
and car use conditions.
The following may occur during regeneration:
increased levels of noise vibration and
harshness (NVH) and reduced engine
performance.
Dedicated messages can appear in the
instrument cluster display as a result of the
condition of the filter. Refer to the opening
paragraph of the "Warning Lights And
Messages" section for further information.
WARNING!
Cargo must be securely tied down before
driving your vehicle. Improperly secured
loads can fly off the vehicle, particularly
at high speeds, resulting in personal
injury or property damage. Follow the roof
rack cautions when carrying cargo on your
roof rack.
CAUTION!
To avoid damage to the roof rack and
vehicle, do not exceed the maximum roof
rack load capacity. Always distribute
heavy loads as evenly as possible and
secure the load appropriately.
Long loads, which extend over the wind
-
shield, should be secured to both the
front and rear of the vehicle.
Place a blanket or other protection
between the surface of the roof and the
load.
Travel at reduced speeds and turn
corners carefully when carrying large or
heavy loads on the roof rack. Wind
forces, due to natural causes or nearby
truck traffic, can add sudden upward
loads. It is recommended to not carry
large flat loads, such as wood panels or
surfboards, which may result in damage
to the cargo or your vehicle.
Load should always be secured to cross
bars first, with tie down loops used as
additional securing points if needed. Tie
loops are intended as supplementary tie
down points only. Do not use ratcheting
mechanisms with the tie loops. Check
the straps frequently to be sure that the
load remains securely attached.

— Swing Gate Open Warning Light
This warning light will illuminate when the
swing gate is open.
NOTE:
If the vehicle is moving, there will also be a
single chime.
— Transmission Temperature Warning
Light — If Equipped
This warning light will illuminate to warn of
a high transmission fluid temperature. This
may occur with strenuous usage such as
trailer towing. If this light turns on, stop the
vehicle and shift the transmission into Park
and allow the vehicle to sit idle (propulsion
system active), until the light turns off. Once
the light turns off, you may continue to drive
normally.
— Vehicle Security Warning Light — If
Equipped
This light will flash at a fast rate for approxi -
mately 15 seconds when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
Yellow Warning Lights
— Anti-Lock Brake (ABS) Warning Light
This warning light monitors the Anti-Lock
Brake System (ABS). The light will turn on
when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and may stay on for as
long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the
brake system is not functioning and service
is required as soon as possible. However, the conventional brake system will continue to
operate normally, assuming the Brake
Warning Light is not also on.
If the ABS light does not turn on when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position, have the brake system
inspected by an authorized dealer.
— Electronic Stability Control (ESC)
Active Warning Light — If Equipped
This warning light will indicate when the
Electronic Stability Control system is Active.
The “ESC Indicator Light” in the instrument
cluster will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN posi -
tion, and when ESC is activated. It should go
out with the engine running. If the “ESC
Indicator Light” comes on continuously with
the engine running, a malfunction has been
detected in the ESC system. If this warning
light remains on after several ignition cycles,
and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see an authorized dealer as soon
as possible to have the problem diagnosed
and corrected.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning
Light is illuminated you could cause the
fluid to boil over, come in contact with hot
engine or exhaust components and cause a
fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated
will eventually cause severe transmission
damage or transmission failure.

ONBOARD DIAGNOSTIC
SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II.
This system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern -
ment regulations.
If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light (MIL). It will also store diag -
nostic codes and other information to assist
your service technician in making repairs.
Although your vehicle will usually be drive -
able and not need towing, see an authorized
dealer for service as soon as possible.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard
Diagnostic system (OBD II) and a connection
port to allow access to information related to
the performance of your emissions controls.
Authorized service technicians may need to
access this information to assist with the
diagnosis and service of your vehicle and
emissions system. For further information, refer to “Cybersecu-
rity” in “Multimedia” in your Owner’s
Manual.
CAUTION!
Prolonged driving with the MIL on could
cause further damage to the emission
control system. It could also affect fuel
economy and driveability. The vehicle
must be serviced before any emissions
tests can be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter
damage and power loss will soon occur.
Immediate service is required.
WARNING!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
CAUTION! (Continued)
If unauthorized equipment is connected
to the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems, including safety related systems,could be impaired or a loss of vehicle
control could occur that may result in
an accident involving serious injury
or death.
Access, or allow others to access, information stored in your vehicle
systems, including personal informa-
tion.
