front, rear and side vehicle lighting
is switched on. You can use the

one side for parking as an additional fea-
ture, refer to page 86.

When you switch off the ignition
with the headlamps on, the head-
lamps go out, and only the parking
lamps remain on.

After parking the vehicle and switching off
the headlamps, operating the headlamp
flasher activates the low beams. You can

you that the lamps have not yet been
switched off. At the same time a message
appears on the Control Display.
Daytime driving lamps*
If you wish, you can leave the light switch in
the low-beam position.
Always observe all applicable laws govern-
ing the use of daytime driving lamps.
You can switch on the parking lamps when
needed using the standard procedure
described under Parking lamps.
Automatic headlamp control
When you set the switch to this
position, the system activates and
switches on and off the low beams
in response to changes in ambient light
conditions, for instance, in a tunnel, at
dawn and dusk, and in rain and snow.
The LED next to the symbol is illuminated
when the low beams are on.
The low beams remain on indepen-
dent of the ambient lighting condi-
tions when you switch on the fog lamps.
With the daytime driving lamps activated,
the low beams are always switched on in

Warning lamp* lights up.
Fuel filler cap is not properly closed
or is missing. Check whether the
fuel filler cap is properly closed.
Fuel specifications
The engine uses lead-free gasoline only.
Required fuel
Premium Unleaded Gasoline,
Minimum Octane Rating: 91.
Minimum Octane Rating corresponds to
the Anti Knock Index AKI and is deter-
mined according to the so-called (R+M)/
2 method.
Do not use leaded gasoline, as other-
wise the lambda probe and catalytic
converter will be permanently damaged.<
Use high-quality brands
Field experience has indicated significant
differences in fuel quality: volatility, compo-
sition, additives, etc., among gasolines
offered for sale in the United States and
Canada. Fuels containing up to and includ-
ing 10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight, that is,
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may
result in drivability, starting and stall-
ing problems, especially under certain
environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the
fuel you are using, we recommend that you
respond by switching to a recognized high-
quality brand.
Failure to comply with these recommenda-
tions may also result in unscheduled main-
tenance.<
