Risk of accident
If the engine is not running, there is no
power assistance for the steering and
brakes. Steering and braking then takes
much more effort.
As a result, you might lose control of the
vehicle, cause an accident and injure your-
self and others.
Do not switch off the engine while driving.

Introduction to the transmission
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any
objects in the driver's footwell. Make sure
that floormats or carpets are correctly
secured and that there is sufficient clear-
ance for the pedals. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. This could
cause you to lose control of your vehicle
and cause an accident. Controls

Refuelling

!
If the wrong fuel has been added by mis-
take, do not switch on the ignition. If you
do, the fuel could enter the fuel lines. The
tank and the fuel lines would then have to
be emptied. Inform a qualified specialist
workshop and have the tank and the fuel
lines emptied completely.
When you open or close the vehicle with the
key or KEYLESS GO*, the fuel filler flap is
automatically unlocked or locked.
The fuel filler flap is to the rear on the right. 1

4 Fuel type X
Turn the fuel filler cap to the left and
remove it.
X Insert the fuel filler cap into the holder
bracket on the inside of filler flap 2.
X Only fill the tank until the pump nozzle
switches off.
! Overfilling the tank could damage the fuel
system.
X To close: replace the fuel filler cap and turn
it clockwise. The fuel filler cap audibly
engages.
X Close the fuel filler flap.
i Vehicles with a diesel engine:
If the tank has been run completely dry, it
will be necessary to bleed the fuel system
(Y page 294). Petrol (EN 228)
! Refuel using only unleaded premium
grade petrol with a minimum octane num-
ber of 95 RON/85 MON conforming to
European standard EN 228.
You could otherwise impair engine output
or damage the engine.
You will find further information about pet-
rol under "Fuel" in the index.
i As a temporary measure, but only when
the recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MO N. Thismay reduce per-
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-
tainer. Operation
