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 operating113● The brake vacuum is sufficient.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
"Climate control" chapter for further information 3 102.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 109.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features, e.g., the rear window
heating, are disabled or switched into
a power saving mode. The fan speed of the climate control system is
reduced to save power.Restart of the engine by the driverVehicles with manual transmission
Depress the clutch pedal to restart the
engine.
If the selector lever is shifted out of
neutral before depressing the clutch
pedal first, control indicator -
illuminates or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 73.Vehicles with manual transmission
automated
Release the brake pedal or move
selector lever out of D to restart the
engine.
Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and the driver's door
is opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
114Driving and operatingParking9Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake. Activate the manual
parking brake without pressing the release button. Apply as
firmly as possible on a downhill slope or uphill slope. Depress
brake pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear before removing the ignition key. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before removing the ignition
key. Turn the front wheels
towards the kerb.
● Close the windows and the sunroof.
● Remove the ignition key from the ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with manual
transmission automated, the key
can only be removed from the
ignition switch when the parking
brake is applied.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 139.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low
load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Note
In the event of an accident with
airbag deployment, the engine is
switched off automatically if the
vehicle comes to a standstill within a
certain time.
118Driving and operatingEngine braking
Automatic mode
When driving downhill, the manual transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached. It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect, select a lower gear in good time when driving downhill. Changing into
manual mode is only possible while
the engine is running.
Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between R and D in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
The most recently engaged gear (see transmission display) remains
engaged when switching off ignition.
With N, no gear is engaged.Therefore always apply the parking
brake when switching off ignition. If
parking brake is not applied, P flashes
in the transmission display and the
key cannot be removed from the
ignition switch. P stops flashing in the
transmission display as soon as the
parking brake is slightly applied.
When the ignition is switched off, the
transmission no longer responds to
movement of the selector lever.
Manual mode
If a higher gear is selected when the
engine speed is too low, or a lower
gear when the speed is too high, the
shift is not executed. This prevents
the engine from running at too low or too high an engine speed. M and the
number of the selected gear will be
flashed, then the current gear is
displayed again..
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
When + or - is selected in automatic
mode, the transmission switches to
manual mode and shifts accordingly.Gear shift indication
The symbol R with a number
alongside it, is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
The adaptive programme tailors
gearshifting to the driving conditions, e.g. greater load or gradients.
Fault
To prevent damage to the manual
transmission automated, the clutch is engaged automatically at high clutch
temperatures.
In the event of a fault, control indicator
g illuminates. Additionally, a
warning message is displayed in the
Driver Information Centre. Vehicle
messages 3 83.
Continued driving is restricted or not
possible, depending on the fault.
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 73.
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 two seconds.
The brakes release automatically as
Driving and operating121soon as the vehicle begins to
accelerate or the two seconds holding
time is over.
The hill start assist is only active when
the engine is running.Ride control systems
Traction Control system The Traction Control system (TC) is a
component of the Electronic Stability
Control (ESC).
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels start to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational after each engine
start as soon as the control indicator
b extinguishes.
When TC operates b flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Deactivation
TC can be switched off when spinning of drive wheels is required: press t
briefly.
122Driving and operating
Control indicator k illuminates.
When TC is deactivated, ESC
remains active.
TC is reactivated by pressing t again.
TC 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.
Electronic Stability Control
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the wheels are braked individually.
ESC operates in combination with the Traction Control system (TC). It
prevents the drive wheels from
spinning.
ESC is operational after each engine
start as soon as the control indicator
b extinguishes.
When ESC operates b flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 74.
Deactivation
For very high-performance driving
ESC can be deactivated:
Press and hold t for a minimum of
five seconds. Control indicator t
illuminates.
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
