Centre
154Driving and operatinggateway, a courtyard or even a
crossing as a parking slot. After selecting reverse gear the system
will start a parking manoeuvre. Take care regarding the availability of the
suggested parking slot.
Surface irregularities, e.g. on construction zones, are not detected
by the system. The driver accepts
responsibility.
Notice
If engaging a forward gear and
exceeding a certain speed, the
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse for the first time,
the parking assist will detect the rear carrier system and provide a buzzing
sound. Press r or D briefly to
deactivate the parking assist.
Notice
After production, the system
requires a calibration. For optimal
parking guidance, a driving distance
of at least 6 miles, including a
number of bends, is required.Side blind spot alert
The Side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system
displays a visual alert in each exterior
mirror, when detecting objects that
may not be visible in the interior and
exterior mirrors.
Side blind spot alert uses some of the advanced parking assist sensors
which are located in the front and rear
bumper on both sides of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● Vehicles outside the side blind zones which may be rapidly
approaching.
● Pedestrians, cyclists or animals.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects a vehicle in the side blind zone while driving
forwards, either while passing a
vehicle or being passed, a yellow warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
yellow as a warning not to change
lanes.
Notice
If the overtaking vehicle is at least
6 mph faster than the vehicle being
overtaken, the warning symbol B in
the relevant exterior mirror may not
illuminate.
Driving and operating155Side blind spot alert is active from
speeds of 6 mph up to 87 mph.
Driving faster than 87 mph
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the
speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both
exterior mirror displays will briefly
illuminate to indicate that the system
is operating.
The system can be activated or
deactivated in the Info-Display,
vehicle personalisation 3 99.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zones The detection zones start at the rear
bumper and extend approx. three metres rearwards and to the sides.
The height of the zone is between
approx. 0.5 metres and two metres off
the ground.Side blind spot alert is designed to
ignore stationary objects, e.g.
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault
Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions.
Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice, slush, or in heavy
rainstorms. Cleaning instructions
3 207.
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.Fuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 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.
156Driving and operatingCaution
Use of fuel that does not comply toEN 228 or E DIN 51626-1 or
equivalent can lead to deposits 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 3 219. A
country specific label at the fuel filler
flap can supersede the requirement.
Fuel for liquid gas operation Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under
its French name GPL (Gaz de Pétrole Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between 105 and 115, depending on the
butane proportion. LPG is stored
liquid at around five to ten bar
pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient
pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full function of the LPG system can only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
Fuel selector
Pressing LPG switches between
petrol and liquid gas operation as
soon as the required parameters (coolant temperature, gas
temperature and minimum engine
speed) have been reached. The
requirements are usually fulfilled after
approx. 60 seconds (depending on
exterior temperature) and the first firm press on the accelerator. The LED
status shows the current operating
mode.
Vehicle care185On version with subwoofer box, the
tools and the towing eye are located
together with the tyre repair kit and
the warning triangle in the box below
the floor cover. To gain access,
remove floor cover: fold rear part to
the front and pull out the cover to the
rear 3 65.
Vehicles with spare wheel
The jack, the wheel bolt wrench, the
tools and two straps for securing a
damaged wheel are in the tool box
below the load compartment floor
cover 3 65.
Wheels and tyres
Tyre condition, wheel condition Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres
on the rear axle.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 225.
Tyre size 185/60 R 15 is only
permitted as winter tyre.In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.

Directional tyres
Directional tyres must be mounted so that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel.
This also applies to vehicles with tyre
pressure monitoring system.
Unscrew the valve cap.
Tyre pressure 3 225.
The tyre pressure information label
on the right door frame indicates the
original equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and fuel economy and will increase tyre
wear.
The tyre pressure tables show all
possible tyre combinations 3 225.
Identify the respective tyre.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table
may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Vehicle care187If the tyre pressure must be reduced
or increased, switch off ignition. After
adjusting tyre pressure switch on
ignition and select the relevant setting on the page Tyre load in the Driver
Information Centre 3 89.
Temperature dependency The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down tyre will show a decreased value,
which does not indicate an air leak.Tyre pressure monitoring
system
The tyre pressure monitoring system
checks the pressure of all four tyres
once a minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information
Centre.
The menu can be selected by
pressing the buttons on the turn
signal lever.
