Driving and operating123
Before restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Key lock release
Some vehicles with an automatic
transmission are equipped with an electronic key lock release system.
The key lock release is designed to
prevent ignition key removal unless
the selector lever is in P.
Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct fuel, performed services and a
sufficiently charged battery. With
temperatures below -30 °C the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position P .Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not have to hold the key in position 3.
Once applied, the system will go on starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
■ Clutch pedal not operated (manual transmission)
■ Brake pedal not operated or selector lever not in P or N
(automatic transmission)
■ Timeout occurred
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is depressed. A battery sensor ensures
that an Autostop is only performed if
the battery is sufficiently charged for
a restart.
Activation The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are fulfilled.

Driving and operating131Manual transmission
To engage reverse, with the vehicle
stationary wait 3 seconds after
depressing the clutch pedal and then press the release button 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 not advisable to drive with the hand resting on the selector lever.
Drive systems
All-wheel drive
The All-Wheel Drive (AWD) system
enhances driving characteristics and
stability, and helps to achieve the best possible driveability regardless of
ground surface. The system is always
active and cannot be deactivated.
The torque is distributed steplessly
between the wheels of the front and rear axle, depending on the driving
conditions. Additionally the torque
between the rear wheels is distributed
depending on the surface.
For optimum system performance,
the vehicle's tyres should not have
varying degrees of wear.
When using a temporary spare
wheel, the AWD system is
automatically disabled.
The AWD system will also be
temporarily disabled to protect the
system from overheating if there is
excessive wheel spin. When the
system cools down, AWD will be
restored.

Driving and operating149Fuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable to run with
E10 fuel that fulfills these standards.
E10 fuel contains up to 10 %
bioethanol.
Use fuel with the recommended
octane rating 3 201. Use of fuel with
too low an 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 E DIN 51626-1 or
equivalent can lead to deposits or
engine damage and may affect
your warranty.
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled combustion and engine damage.
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and loss of
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.

Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
5. Unscrew the wheel nuts. 6. Change the wheel. Spare wheel 3 184.
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuring that it locates securely and tighten
each nut in a crosswise
sequence. Tightening torque is
140 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
Install centre cap on alloy wheels.
11. Install vehicle jacking point cover on versions with sill panelling.
12. Stow the replaced wheel 3 184
and the vehicle tools 3 172.
13. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.
Have the defective tyre renewed or
repaired as soon as possible.Jacking position for lifting
platform
Rear arm position of the lifting
platform centrically under the recess
of the sill.
