Driving and operating127During an Autostop, the heating and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
● The stop-start system is not manually deactivated.
● The bonnet is fully closed.
● The driver's door is closed or the driver's seat belt is fastened.
● The vehicle battery is sufficiently charged and in good condition.
● The engine is warmed up.
● The engine coolant temperature is not too high.
● The engine exhaust temperature is not too high, e.g. after driving
with high engine load.
● The ambient temperature is above -5 °C.
● The climate control system allows an Autostop.● 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 more
details 3 116.
Immediately after motorway driving,
an Autostop may be inhibited.
New vehicle running-in 3 124.
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.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 84.Vehicles with manual transmission
automated:
Release the brake pedal or move
selector lever out of D to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
130Driving and operatingManual transmission
To engage reverse, depress the
clutch pedal and press the release button on the selector lever and
engage the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
Caution
It is not advisable to drive with the hand resting on the selector lever.
Gear shift indication 3 85.
Stop-start system 3 126.
Manual transmission
automated
The automated manual transmission permits manual gearshifting (manual
mode) or automatic gearshifting
(automatic mode), both with
automatic clutch control.
Manual shifting is possible by tapping the selector lever in manual mode.
Notice
When unlocking or opening a
vehicle door, a sound may be
audible caused by the hydraulic
system.
132Driving and operatingAlways move the selector lever in the
appropriate direction as far as it will
go. Upon release, it automatically
returns to the centre position.N:neutral positionD/M:switch between automatic (D)
and manual (M) shift mode.
The transmission display
shows either D or M with the
selected gear<:upshifting in manual mode]:downshifting in manual modeR:reverse gear. Engage only
when vehicle is stationary
If selector lever is moved from R to the
left, D is directly engaged.
If selector lever is moved from D to
< or ], the manual mode M is
selected and the transmission shifts.
Starting off
Depress the brake pedal and move
the selector lever to D/M or R. If D is
selected, transmission is in automatic mode and first gear is engaged. If R
is selected, reverse gear is engaged.
The vehicle starts to move when the
brake is released.
To start-off without depressing the
foot brake, accelerate immediately
after engaging a gear as long as D or
R flashes.
If neither the accelerator nor the
brake pedal are depressed, no gear is engaged and D or R flashes for a
brief time in the display.
Stopping the vehicle
In D, first gear is engaged and the
clutch is released when the vehicle is
stopped. In R, reverse gear remains
engaged.
Engine 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 intomanual mode is only possible while
the engine is running or during an
Autostop.
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.
Driving and operating133Tyre pressure monitoring systemTo start the sensor matching process
of the tyre pressure monitoring
system, the selector lever must be
moved and held in position N for
five seconds. P illuminates in the
transmission display to indicate that
the sensor matching process can be
started.
Tyre pressure monitoring system
3 183.
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. A warning
message is displayed in the Driver
Information Centre. Vehicle
messages 3 94.
If engine speed is too low, the
transmission automatically shifts to a
lower gear.
If engine speed is too high, the
transmission only switches to a higher gear via kickdown.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
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● The adaptive programme tailors gearshifting to the driving
conditions, e.g. greater load or
gradients.Kickdown
If the accelerator pedal is pressed down completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
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 94.
Continued driving is restricted or not
possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.
Driving and operating141Automatic 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 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.Speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum speed.
The maximum speed can be set at a
speed above 15 mph.
The driver can only accelerate up to
the preset speed. Deviations from the
limited speed may occur when driving
downhill.
The preset speed limit is displayed in
the Driver Information Centre when
the system is active.
ActivationPress L. If cruise control has been
activated before, it is switched off when speed limiter is activated and
the control indicator m extinguishes.
Set speed limit With speed limiter active, hold thumb
wheel turned to RES/+ or briefly turn
to RES/+ repeatedly until the desired
maximum speed is displayed in the
Driver Information Centre.
Alternatively accelerate to the desired speed and briefly turn thumb wheel to
SET/- : the current speed is stored as
maximum speed. Speed limit is
displayed in the Driver Information Centre.
Vehicle care163BrakesIn the event of minimum thickness ofthe brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake and clutch fluid 3 208.
Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the vehicle battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to vehicle battery
discharge. Disconnect the clamp from
the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
The anti-theft alarm siren must be deactivated as follows: Switch theignition on then off, disconnect the
vehicle's battery within 15 seconds.

Service and maintenance209Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 212.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze. Consult a
workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. Innorthern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional coolant additives will be rejected.
Brake and clutch fluidOver time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified interval.
