Auxiliary Switches — If Equipped
Four auxiliary switches located in the lower
switch bank of the instrument panel can be
used to power various electrical devices. You
have the ability to configure the functionality
of the auxiliary switches via the Uconnect
settings. All switches can be configured for
setting the switch type operation to latching
or momentary, power source of either battery
or ignition, and ability to hold last state
across key cycles.NOTE:
Holding last state conditions are met when
switch type is set to latching and power
source is set to ignition.
For more information, refer to “Uconnect
Settings” in “Multimedia” in your owner’s
manual.
For the connection and installation of your
electrical devices refer to your authorized
dealership.
ENVIRONMENTAL
PROTECTION SYSTEMS
Gasoline Particulate Filter (GPF) — 2.0L
T4 200kW Petrol Versions Only
The Gasoline Particulate Filter is a mechani-
cal filter, integral to the exhaust system,
which physically traps carbon particles pres-
ent in the exhaust gases of 2.0L T4 200kW
petrol engine.The particulate filter is needed to eliminate
almost all carbon particle emissions in com-
pliance with current/future regulations and
standards.
Since this filter physically traps particulates,
it must be cleaned (regenerated) during nor-
mal driving operation to remove carbon par-
ticles. The regeneration procedure is con-
trolled 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 harsh-
ness (NVH) and reduced engine perfor-
mance.
Dedicated messages can appear in the in-
strument cluster display as a result of the
condition of the filter. Refer to the opening
paragraph of the "Warning Lights And Mes-
sages" section for further information.

MESSAGE DESCRIPTION
Engine Will Not Start Service Ad-
Blue System See DealerNOTE:
• The display may take up to five seconds to update after adding 2 gallons (7.5 Liters) or more of AdBlue
(UREA) to the AdBlue (UREA) tank. If you have a fault related to the AdBlue (UREA) system, the display
may not update to the new level. See an authorized dealer for service.
• AdBlue freezes at temperatures lower than 51.8°F (11°C). If the car stands for a long time at this tem-
perature, refilling could be difficult. For this reason, it is advised to park the vehicle in a garage and/or
heated environment, and wait for the AdBlue (UREA) to return to liquid state before topping up.

quiredThe engine control unit has detected an issue with the gasoline particulate filter system. See an autho-
rized dealer.
Exhaust System Regeneration in
Process Continue DrivingThe 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. The driver should continue driving nor-
mally. This message will continue to appear until regeneration is complete.

WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate in

cated message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive and/or alternativeto the information contained in the Owner’s
Manual, which you are advised to read care-
fully in all cases. Always refer to the informa-
tion in this chapter in the event of a failure
indication. All active telltales will display first
if applicable. The system check menu may
appear different based upon equipment op-
tions and current vehicle status. Some tell-
tales are optional and may not appear.

faster, with the transmission in PARK or
NEUTRAL, until the light turns off. Once the
light turns off, you may continue to drive
normally.
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.

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 Warn-
ing 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 in-
spected by an authorized dealer.

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.
• The “ESC Off Indicator Light” and the
