formance and increase petrol consump-
tion. Avoid driving at full throttle.
In some countries, the available petrol qual-
ity may not be sufficient and could cause
coking around the inlet valve. In such
cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios given on the con-

Refuel using only super unleaded petrol
with a minimum octane number of
98 RON/88 MON conforming to European
standard EN 228.
You could otherwise impair engine output
or damage the engine.
You will find further information about pet-

If the recommended fuel is not available
and only as a temporary measure, you may
also use premium unleaded petrol,
95 RON/85 MON. This may reduce per-
176
formance and increase petrol consump-
tion. You must avoid driving at full throttle.
!
In emergencies, and only when the rec-
ommended fuel is not available, you may
also use standard unleaded petrol,
91 RON/82.5 MON. However, using this
fuel results in considerably higher petrol
consumption and significantly reduced per-
formance. Avoid driving at full throttle, and
only drive in drive program C.
If no fuel other than regular petrol fuel
91 RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service.

There is a risk of injury if the bonnet is open,
even if the engine is not running.
Some engine components can become
very hot.
To avoid the risk of burns, only touch those
components described in the Owner's Man-
ual and observe the relevant safety notes.
G Risk of injury
The radiator fan between the radiator and
the engine can start automatically, even if
the key has been removed from the ignition
lock. For this reason you must not reach
into the turning area of the fan. You can
otherwise be injured.
