Control of the vehicle Never coast with engine not
running
Many systems will not function in this
situation (e.g. brake servo unit, power steering). Driving in this manner is a
danger to yourself and others.
All systems function during an
Autostop.
Stop-start system 3 111.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
Driving and operating109Use only floor mats, which fit properly
and are fixed by the retainers on the
driver side.
Driving downhill
Engage a gear when driving downhill
to ensure that sufficient brake
pressure is available.
Steering If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.
Control indicator c 3 75.Caution
Vehicle equipped with electric
power steering:
If the steering wheel is turned until it reaches the end of its travel and
is held against that position for an
extended period of time, power
steering assistance may be
reduced.
If the steering assistance is used
for an extended period of time,
power assistance may be
reduced.
Power steering assistance should
return back to normal when the
system has cooled down.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and engine oil consumption may be
higher.
Autostop may be inhibited to allow for
charging of the vehicle battery.
Ignition switch positions
Turn key:
120Driving and operatingFault9Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Manual parking brake9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
brake pedal at the same time.
Control indicator R 3 74.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, the brakes
remain on for a further 2 seconds. The brakes release automatically as soon
as the vehicle begins to accelerate or the 2 seconds holding time is over.
Driving and operating123ESC is reactivated by pressing t
again. If the TC system was
previously disabled, both TC and
ESC are reactivated. k and t
extinguish when TC and ESC are
reactivated.
ESC is also reactivated the next time
the ignition is switched on.
Fault
If there is a fault in the system, the control indicator b illuminates
continuously and a warning code
appears in the Driver Information
Centre. The system is not
operational.
Have the cause of the fault remedied
by a workshop.
City mode City mode is a feature which enablesincreased steering assistance during
lower speed conditions, e.g. city
traffic or parking. Steering assistance
is increased for greater convenience.Activation
Press B when engine is running. The
system works from standstill up to
60 km/h, and also in reverse gear. Above this speed, the system
changes to normal mode. When
activated, City mode engages
automatically below 60 km/h.
An illuminated LED in the City mode
button indicates that the system is
active and 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 3 111.
Deactivation
Press B. The LED in the button
extinguishes.
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
Driving and operating127By switching off the ignition, speed
limiter is also deactivated, but the
speed limit will be stored for next
speed limiter activation.
Parking assist
Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic signals
and display indication.
The system has three ultrasonic
parking sensors in the rear bumper.
Activation
When reverse gear is engaged, the
system is ready to operate
automatically.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle. The interval between the
sounds becomes shorter as the
vehicle gets closer to that obstacle.
When the distance is less than
approx. 40 cm, the sound is
continuous.
Deactivation
The system automatically switches
off when reverse gear is disengaged.
The system might not detect the
obstacle when the vehicle is driven above 10 km/h.
Fault
In the event of a fault in the system,
control indicator r illuminates in the
instrument cluster 3 75.
Additionally if the system does not work due to temporary conditions like
snow covered sensors, r
illuminates.
128Driving and operatingBasic notes on parking assist
systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and
correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● No operation of turn lights.
● No brake pedal operation.
● No active accelerator operation or speeding-up.
● No active steering.
If the driver is performing these
actions, no warning will be issued.
Activation
The lane departure warning system is activated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on. When control indicator ) in the
instrument cluster illuminates green, the system is ready to operate.
The system is only operable at
vehicle speeds above 56 km/h and if lane markings are available.
130Driving and operatingCaution
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 equivalent can lead todeposits 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 3 182. A
country specific label at the fuel filler
flap can supersede the requirement.
Fuel additive
Fuel should contain detergent
additives that help prevent engine
and fuel system deposits from
forming. Clean fuel injectors and
intake valves will allow the emission
control system to work properly. In
certain countries fuel does not
contain sufficient quantities of
additive to keep fuel injectors and
intake valves clean. In these
countries a fuel additive is required for
some engines to make up for this lack
of detergency. Only use fuel additive
approved for the vehicle.
Adding fuel additive to the filled fuel
tank is required at least every 15,000 km or after one year, whichever
occurs first. For further information,
contact your workshop.
Prohibited fuels
Fuels containing oxygenates such as
ethers and ethanol, as well as
reformulated fuel, are available in
some cities. If these fuels comply with the previously described
specification, then they are
acceptable to use. However, E85(85% ethanol) and other fuels
containing more than 15% ethanol
must be used only in FlexFuel
vehicles.Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
This damage would not be
covered by the vehicle warranty.
Some fuels, mainly high octane
racing fuels, can contain an octane
enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use fuels or fuel additives with MMT as they can
reduce spark plug life and affect
emission control system
performance. The malfunction
indicator light Z may illuminate 3 74.
If this occurs, seek the assistance of
a workshop.
