DRIVING AND OPERATING
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the
windscreen may help.
A camera blocked message may
display if the camera is blocked.
Cleaning the outside of the
windscreen behind the rearview
mirror may correct the issue. Some
driver assistance systems may have
reduced performance or not work at
all. An LKA or LDW unavailable
message may display if the systems
are temporarily unavailable. This
message could be due to a blocked
camera. The LKA system does not
need service. Clean the outside of the
windscreen behind the rearview
mirror.
LKA assistance and/or LDW alerts
may occur due to tar marks, shadows,
cracks in the road, temporary or
construction lane markings, or other
road imperfections. This is normal
system operation; the vehicle does not
need service. Turn LKA off if these
conditions continue.
Fuel
Use the recommended fuel for proper
vehicle maintenance.
Use unleaded petrol with a posted
octane rating of 95 RON or higher.
Unleaded petrol rated at 91 RON can
be used, but acceleration and fuel
economy will be reduced, and an
audible knocking noise may be heard.
If this occurs, use petrol rated at 95
RON as soon as possible, otherwise
the engine could be damaged. If heavy
knocking is heard when using
unleaded petrol rated at 95 RON, the
engine needs service.
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
.
Fuel with any amount of
methanol, methylal, and
aniline. These fuels can

corrode metal fuel system
parts or damage plastic and
rubber parts.
.
Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control system
and spark plugs.
.
Fuel with a posted octane
rating of less than the
recommended fuel. Using this
fuel will lower fuel economy
and performance, and may
decrease the life of the
emissions catalyst.
Fuel Additives
Petrol should contain detergent
additives that help prevent engine and
fuel system deposits from forming.
Clean fuel injectors and intake valves
will allow the emission control system
to work properly. Some petrol does not
contain sufficient quantities of
