122Driving and operatingCaution
Fuel grades other than those listedon pages 3 135, 3 183 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Manual transmission
To engage reverse, with the vehicle
stationary, wait three seconds after
depressing the clutch pedal, pull up
the collar on the selector lever and
engage the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
Caution
It is inadvisable to drive with hand
resting on the selector lever.
When gearshifting is recommended
to improve fuel economy, control
indicator [ or Ò illuminates in the
Driver Information Centre.
Gear shifting control indicator 3 86.
Stop-start system 3 117.

Driving and operating125Switch off engine if stopping for alengthy period, e.g. in traffic jams.
Engine braking
Automatic mode
When driving downhill, the manual
transmission automated does not shift into higher gears until a fairly
high engine speed has been reached.
It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect, select a lower gear in good time when driving downhill.
Rocking the vehicle Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud, snow or a hole. Move the
selector lever between R and A/M (or
between + and -) in a repeat pattern,
while applying light pressure to the
accelerator pedal. Do not race the
engine and avoid sudden
acceleration.Parking
Apply the parking brake. The mostrecently engaged gear (see
transmission display) remains
engaged.Caution
Do not leave the vehicle with the
transmission in position N.
When the ignition is switched on, a
warning chime will sound when the
vehicle is parked if the transmission is still in N.
When the ignition is switched off, the transmission no longer responds to
movement of the selector lever.
Manual mode If engine speed is too low, the
transmission automatically shifts to a
lower gear.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions. If engine
speed is too high, the transmission
only switches to a higher gear via
kickdown 3 125.
When gearshifting is recommended
to improve fuel economy, control
indicator [ or Ò illuminates in the
Driver Information Centre 3 86.
Electronic driving programmes
Eco mode E
When automatic mode is engaged,
the Eco mode can be selected to
reduce fuel consumption.

Driving and operating135Fuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or
equivalent.
The engine is capable of running with fuel that contains up to 10% ethanol(e.g. named E10).
Use fuel with the recommended
octane rating. A lower octane rating
can reduce engine power and torque
and slightly increases fuel
consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to EN 228 or equivalent can lead todeposits or engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine-specific requirements
regarding octane rating are given in
the engine data overview 3 183. A
country-specific label at the fuel filler
flap can supersede the requirement.
Fuel for diesel engines Only use diesel fuel that complies
with EN 590 and which has a sulphur
concentration of max. 10 ppm.
Fuels with a biodiesel (compliant with
EN 14214) content of max. 7% by
volume may be used (e.g. named
B7).
If travelling in countries outside the
European Union occasional use of Euro-Diesel fuel with a sulphur
concentration below 50 ppm is
possible.Caution
Frequent usage of diesel fuel containing more than 15 ppm
sulphur will cause severe engine
damage.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.

136Driving and operatingLow temperature operation
At temperatures below 0° C, some diesel products with biodiesel blends
may clog, freeze or gel, which may
affect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0°C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20° C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage on the fuel
injection system.
Fuel for natural gasoperation
Use natural gas with a methane
content of approx. 78 - 99%. L-gas
(low) has approx. 78 - 87% and H-gas (high) has approx. 87 - 99%. Biogas
with the same methane content can
also be used if it has been chemically
prepared and desulphurised.
Only use natural gas or biogas that complies with DIN 51624.Liquid gas or LPG must not be used.
Refuelling
Fuel filler flap is located at left rear
side of vehicle.9 Danger
