138Driving and operatingConditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the ambient temperature is not too low
● the defrosting function is not activated
● the climate control system does not inhibit an Autostop
● the rear air conditioning system is
not activated
● the brake vacuum is sufficient● the self-cleaning function of the diesel particle filter is not active
3 142
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See "Climate control" chapter for
further information 3 116.
Immediately after motorway driving
an Autostop may be inhibited.

Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.Restart of the engine by the driverManual transmission
With the selector lever in neutral,
depress the clutch pedal to restart the
engine.
Note
If any gear is selected, the clutch
pedal must be fully depressed to
restart the engine.
If the engine does not restart first
time, depress clutch pedal fully again.Manual transmission automated
With the selector lever in position N
(or A/M ) and the parking brake
released, release the brake pedal to
restart the engine.
Engaging reverse gear or depressing
the accelerator pedal may also restart the engine.
The green control indicator Ï will
extinguish in the instrument cluster
when the engine is restarted. If
certain conditions are not fulfilled, a
restart will not take place; start using
the ignition key.

150Driving and operatingManual transmission
To engage reverse, with the vehicle
stationary depress the clutch pedal, pull up the collar 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 inadvisable to drive with hand
resting on the selector lever.
Upshift 3 98.

Manual transmission
automated
The manual transmission automated (MTA) permits manual (manual
mode) or automatic gear shifting
(automatic mode), both with
automatic clutch control.
Transmission display
Shows the mode and current gear.
Driving and operating151Starting the engine
Depress the brake pedal when
starting the engine. If the brake pedal
is not depressed, T illuminates in the
transmission display and the engine
cannot be started.
When the brake pedal is depressed,
the transmission automatically shifts
to N (neutral); "N" appears in the
transmission display and the engine
can be started. There may be a slight delay.
Selector leverAlways move the selector lever in the
appropriate direction as far as it will
go. Upon release, it automatically
returns to the centre position.N:neutralA/M:switch between automatic and manual mode
The transmission display
shows "A" when in automatic
mode.R:reverse gear
Engage only when vehicle is
stationary. The transmission
display shows "R" when
reverse gear is engaged.+:shift to a higher gear.-:shift to a lower gear.
Starting off
When the engine is started, the
transmission is in automatic mode. Depress the brake pedal and move
the selector lever towards + to
engage first gear.
If R is selected, reverse gear is
engaged. The vehicle starts to move
when the brake pedal is released. To
start off quickly, release the brake pedal and accelerate immediately
after engaging a gear.
In automatic mode the transmission
shifts to other gears automatically,
dependent on driving conditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display.
To engage first gear, depress brake
pedal and move selector lever
towards + or -. Shift to a higher or
lower gear by moving selector lever to + or -. Gears can be skipped by
moving the selector lever repeatedly
at short intervals.
Stopping the vehicle In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped.
In R, reverse gear remains engaged.
When stopping on gradients, engage
parking brake or depress the brake
pedal. To prevent overheating of the
clutch, an intermittent audible
Driving and operating153Activate the Winter mode if you have
problems starting off on a slippery
road surface.
Activation
Press V. Control indicator V is shown
in the transmission display. The
transmission switches to automatic
mode and the vehicle starts off in a
suitable gear.
Deactivation
The Winter mode is switched off by:
● pressing V again
● turning off the ignition
● switching to manual mode
In order to protect the transmission at
extremely high clutch temperatures,
an intermittent audible warning may
sound. In such cases, depress the
brake pedal, select "N" and apply the parking brake to allow the clutch to
cool down.Laden mode kg
It is possible to use the Laden mode
in both manual and automatic modes. In both cases, the gearshifting
patterns are adapted automatically
for carrying an increased payload.
Activation
Press kg. Control indicator kg is
shown in the transmission display.
The transmission will then select
optimized gearshift patterns.
Deactivation
The Laden mode is switched off by:
● pressing kg again
● turning off the ignition
Kickdown If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear
depending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault
In the event of a fault, control indicator W is shown in the transmission
display. Continued driving is possible
provided the vehicle is driven with
care and anticipation.
Have the cause of the fault remedied
by a workshop.
154Driving and operatingInterruption of power supplyThe clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 213.
If the cause of the fault is not a
discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the
drive wheels raised off the ground
3 215.
Towing the vehicle 3 215.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 98.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
Control indicator u 3 98.
Fault
If control indicators u and A
illuminate with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre, there is a fault in
the ABS. The brake system remains
operational but without ABS
regulation.
Driving and operating161Increase speedWith cruise control active, the vehicle
speed can be increased continuously or in small increments by holding
down or tapping < repeatedly.
When the switch is released the
current speed is stored and
maintained.
Alternatively, accelerate to the
desired speed and store by pressing
< .
Reduce speed With cruise control active, the vehicle
speed can be decreased
continuously or in small increments
by holding down or tapping ]
repeatedly.
When the switch is released the
current speed is stored and
maintained.Deactivation
Press $: cruise control is deactivated
and the green control indicator m
extinguishes in the instrument cluster.
Automatic deactivation: ● vehicle speed drops below 30 km/h
● the brake pedal is depressed
● the clutch pedal is depressed
● selector lever in N
The speed is stored and a
corresponding message appears in
the Driver Information Centre.
Reactivation
Press R at a speed above 30 km/h.
If the stored speed is much higher
than the current speed, the vehicle
will accelerate powerfully until the
stored speed is obtained.
Pressing < will also reactivate the
cruise control function, but at the
current vehicle speed only, not the stored speed.
Deleting the stored speedPress m: Green control indicators
U and m extinguish in the instrument
cluster.
Cruise control speed limiter
The speed limiter prevents the
vehicle exceeding a preset maximum speed above 30 km/h.
172Driving and operatingIn the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded (including all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment audible
warning
For vehicles fitted with towing
equipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
signals.
The pitch of the audible warning will
change if a turn signal light on the
trailer or the towing vehicle fails.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While the system is working,keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic Stability
Program (ESP) 3 157.Auxiliary features
