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. 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
Top Tier Fuel (Petrol)
GM recommends the use of TOP TIER
Detergent Gasoline to keep the engine clean,
reduce engine deposits, and maintain
optimal vehicle performance. Look for the
TOP TIER Logo or see www.toptiergas.com
for a list of TOP TIER Detergent Gasoline
resellers and applicable countries.
Recommended Fuel (Petrol)
Driving and Operating
Use the recommended fuel for proper
vehicle maintenance. Use unleaded petrol
with a posted octane rating of 95 RON or
higher and with ethanol up to 10% by
volume. 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. If heavy knocking is heard when
using unleaded petrol rated at 95 RON, the
engine needs service.
Prohibited Fuels (Petrol)
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
