Driving and operating133starting 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 depressed (manual transmission).
● Brake pedal not depressed 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 pedal is released.Depending on driving conditions, the
overrun cut-off may be deactivated.
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.Deactivation
Deactivate the stop-start system
manually by pressing Ï.
Deactivation is indicated when the
LED in the button extinguishes.
Autostop If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal.
● Move the selector lever to neutral.
● Release the clutch pedal.

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.The deactivation of the AWD system
will be indicated by a message on the
Driver Information Centre.
If a service message or warning
code S73 is displayed on the Driver
Information Centre, there is a
malfunction in the AWD system. Seek
the assistance of a workshop.

Driving and operating163The lane departure warning system is
activated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on.
When the control indicator ) in the
instrument cluster illuminates green,
the system is ready to operate.
The system is only operable at
vehicle speeds above 35 mph and if
lane markings are available.
When the system recognises an
unintended lane change, the control
indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.
Deactivation
The system is deactivated by
pressing ), the LED in the button
extinguishes.
At speeds below 35 mph the system
is inoperable.
Fault
The lane departure warning system
may not operate properly when:
● the windscreen is not clean
● there are adverse environmental conditions like heavy rain, snow,
direct sunlight or shadows
The system can not operate when no
lane marking is detected.Fuel
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.

2. Fold out the wheel wrench and
install ensuring that it is located
securely and loosen each wheel
nut by half a turn.
3. Ensure the jack is correctly positioned under the relevant
vehicle jacking point.
Depending on the equipment, first
remove the covers from the
jacking points.
4. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.Attach wheel wrench and with the jack correctly aligned rotate wheelwrench until wheel is clear of the
ground.
5. Unscrew the wheel nuts.
6. Change the wheel. Spare wheel 3 204.
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.

Vehicle care20710. Align the valve hole in the wheelcover 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 panels.
12. Stow the replaced wheel 3 204
and the vehicle tools 3 192.
13. Check the tyre pressure of the installed tyre and the wheel nuttorque as soon as possible.
Have the defective tyre renewed or
repaired as soon as possible.
Stowing a damaged full size
wheel in the load compartment
The spare wheel well is not designed
for other tyre sizes than the spare
wheel.
A damaged full size wheel must be
stowed in the load compartment and
secured with a strap.
Vehicle tools 3 192.
To secure the wheel: 1. Position the wheel in the middle of
the load compartment.
2. Place the loop end of the strap through the lashing eye on one
side.
3. Place the hook end of the strap through the loop and pull it until
the strap is fastened securely to
the lashing eye.4. Insert the strap through the spokes of the wheel as shown in
the illustration.
5. Mount the hook to the opposite lashing eye.
6. Tighten the strap and secure it using the buckle.
9 Danger
Always drive with folded up and
engaged rear seat backrests when stowing a damaged full size wheel
in the load compartment.
