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 harsh
-
ness (NVH) and reduced engine perfor -
mance.
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.
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.
CAUTION! (Continued)
