Driving and operating137
Activation
Press button B when engine is
running. The system works from
standstill up to 22 mph, and in reverse gear. Above this speed the system
changes to normal mode. When
activated, City mode engages
automatically below 22 mph.
An illuminated LED in the City mode
button indicates that the system is
active.
Additionally, a message pops-up in
the Driver Information Centre.
City mode remains active during an
Autostop, but is only operational
when the engine is running.
Stop-start system 3 124.
Deactivation
Press button B; LED in the button
extinguishes and a message pops-up
in the Driver Information Centre.
Each time the engine is started, City
mode is deactivated.
Overload If the steering in City mode is heavily
loaded, e.g. in long parking
manoeuvres or heavy city traffic, the
system is deactivated for overheat
protection. Steering operates in
normal mode until City mode
activates automatically.Fault
In the event of a fault in the system,
c illuminates and a message is
displayed in the Driver Information
Centre.
Vehicle messages 3 97.
System calibration
If control indicators c and b
illuminate simultaneously, a
calibration of the power steering
system is necessary. This can occur
e.g. when turning the steering wheel for one rotation with ignition switched
Driving and operating139
Switching on
Press button m; control indicator m in
instrument cluster illuminates white.
Activation
Accelerate to the desired speed and
turn thumb wheel to SET/-, the
current speed is stored and
maintained. Control indicator m in
instrument cluster illuminates green. Accelerator pedal can be released.
Vehicle speed can be increased by depressing the accelerator pedal.
When the accelerator pedal is
released, the previously stored speed is resumed.
Cruise control remains activated
while gearshifting.
Increase speed
With cruise control active, hold thumb wheel turned to RES/+ or briefly turn
to RES/+ repeatedly: speed
increases continuously or in small
increments.
Alternatively accelerate to the desired speed and store by turning to SET/-.
Reduce speed
With cruise control active, hold thumb
wheel turned to SET/- or briefly turn to
SET/- repeatedly: speed decreases
continuously or in small increments.
Deactivation
Press button y; control indicator m in
instrument cluster illuminates white.
Cruise control is deactivated. Last
stored speed remains in memory for
later speed resume.
Automatic deactivation:
■ Vehicle speed is below approx. 20 mph.
■ Vehicle speed is above approx. 125 mph.
■ The brake pedal is depressed.
■ The clutch pedal is depressed for a
few seconds.
■ Engine speed is in a very low range.
■ The Traction Control system or Electronic Stability Control is
operating.
Resume stored speed Turn thumb wheel to RES/+ at a
speed above 20 mph. The stored
speed will be obtained.
Switching off
Press button m; control indicator m in
instrument cluster extinguishes. The
stored speed is deleted.
Switching off the ignition also
switches off cruise control and
deletes the stored speed.
Driving and operating151
The system can be activated or
deactivated in the Info-Display,
vehicle personalisation 3 100.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zones
The detection zones start at the rear
bumper and extend approx.
3 metres rearwards and to the sides.
The height of the zone is approx.
between 0.5 metres and 2 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
3 203.
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 enginesOnly use unleaded fuel that complies
with European standard EN 228 or E DIN 51626-1 or equivalent.
The engine is capable of running with E10 fuel that fulfills these standards.E10 fuel contains up to 10 %
bioethanol.
Use fuel with the recommended
octane rating 3 215. 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.
152Driving 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 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 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 5 - 10 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 the LPG button 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.LED off=petrol operationLED illumi‐ nates=liquid gas operationLED
flashes=no switching is
possible, one type of
fuel is empty
As soon as the liquid gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
Every six months, run the petrol tank
down until control indicator Y
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Driving and operating153
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
■ Is there enough liquid gas present?
■ Is there enough petrol present for starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If the gas odour persists, do not start
the engine. Have the cause of the
fault remedied by a workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Notice
In the event of an accident, switch off
the ignition and lights.
Refuelling9 Danger
Before refuelling, switch off the
engine.
Switch off any mobile phones.
Follow the operating and safety
instructions of the gas station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
