140Driving and operatingHeating functionalitiesNote
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will
be resumed after some minutes.
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.
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.
DeactivationDeactivate the stop-start system
manually by pressing Ò. The
deactivation is indicated when the
LED in the button illuminates.
AutostopVehicles with manual transmission
An Autostop can be activated at a
standstill.
Activate an Autostop as follows: ● Depress the clutch pedal.
● Set the selector lever to neutral.
● Release the clutch pedal.
The engine will be switched off while the ignition stays on.Vehicles with automatic transmissionIf the vehicle is at a standstill with
depressed brake pedal, Autostop is
activated automatically.
The engine will be switched off while the ignition stays on.
The stop-start system will be disabled
on inclines of 12% or more.

Driving and operating157Standard mode 2
This mode is calibrated for a low level of wheel spin, based on the differenttypes of grip generally encountered in
normal day to day driving.
Everytime the ignition is switched off,
the system is automatically reset to
this mode.
Snow mode 3
This mode adapts to the grip
conditions encountered by each
wheel when starting.
When advancing, the system
optimises wheel spin to guarantee the
best acceleration based on the
available traction. Recommended in
cases of deep snow and steep
inclines.
This mode is active up to a speed of
50 km/h.
Mud mode 4
This mode allows considerable wheel spin at start-up for the wheel with the
least grip, this removes mud and re-
establishes traction.Simultaneously, the wheel with the
most grip is provided with the most
torque possible.
This mode is active up to a speed of
80 km/h.
Sand mode 1
This mode allows a small amount of
simultaneous wheel spin on the two
drive wheels, enabling the vehicle to
advance and reduce the risk of
sinking.
This mode is active up to a speed of
120 km/h.Caution
Do not use the other modes on
sand as the vehicle may become
stuck.
Sport mode
Sport mode adapts the settings of
some vehicle systems to a sportier
driving style.
Activation
Press SPORT when engine is
running.
LED in the button illuminates when
sport mode is active and a status
message appears in the Driver
Information Centre.

Vehicle care229● Never crawl under a jacked-upvehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
Tightening torques
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
100 Nm.
Tightening torque for steel wheels is 115 Nm.
Just use the correct wheel bolts for the respective wheels.
Jacking positions
The jacking positions shown refer to
the use of lifting arms and accessory
jacks used for changing winter /
summer tyres.
Rear arm position of the lifting
platform centrically under the relevant vehicle jacking point.
Front arm position of the lifting
platform centrically under the relevant vehicle jacking point.

232Vehicle care
3. Ensure the jack is correctlypositioned under the relevant
vehicle jacking point.
4. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Ensure that the edge of the body
fits into the notch of the jack.
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 3 230
7. Screw on the wheel nuts.
8. Lower the vehicle and remove jack.
9. Install the wheel wrench ensuring that it is located securely and
tighten each bolt in a crosswise
sequence. Tightening torque is
115 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
11. Stow the replaced wheel 3 230,
the vehicle tools 3 220 and the
adapter for the locking wheel nuts.
12. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.
