Driving and operating135Steering wheel lockRemove key from ignition switch and
turn steering wheel until it engages.9 Danger
Never remove the key from
ignition switch during driving as
this will cause steering wheel lock.
Starting the engine
Manual transmission: operate clutch.
Manual transmission automated:
operate brake; transmission
automatically shifts to N.
Do not accelerate.
Turn the key to position 2 for
preheating, and hold until control
indicator N extinguishes from the
Driver Information Centre.
Note
Depending on vehicle, if a gear is
engaged during preheating, a
message may appear in the Driver
Information Centre (DIC) 3 102
indicating that the clutch pedal must be depressed when starting the
engine.
Turn key to position 3 and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.Note
Rear-wheel drive: When starting on
a level surface with an unladen
vehicle, it is recommended that
second gear is selected when
starting off.
Before restarting or to switch off the
engine, turn key back to 0.
During an Autostop, the engine can
be started by depressing the clutch
pedal. Stop-start system 3 136.
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
136Driving and operatingIdle speed control
To increase the idle speed press the
switch. After a few seconds the
function will be activated.
The function will be deactivated
when:
● The clutch pedal is depressed.
● The accelerator pedal is depressed.
● MTA is not in N (neutral).
● Vehicle speed is above 0 km/h. ● Control indicator A, W or C
illuminate in the instrument
cluster.
To increase or decrease the fast idle
speed rate, consult a workshop.
Note
When the fast idle function is
activated, the stop-start system is
automatically deactivated.
Stop-start system 3 136.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam.It restarts the engine automatically as
soon as the clutch pedal is depressed (manual transmission) or the brake
pedal is released (manual
transmission automated).
A vehicle battery sensor ensures that
an Autostop is only performed if the vehicle battery is sufficiently charged
for a restart.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
If the below conditions are not
fulfilled, an Autostop is prohibited and
control indicator \ illuminates in the
instrument cluster 3 100.
Driving and operating137Deactivation
Deactivate the stop-start system
manually by pressing Î.
Deactivation is indicated when the
LED in the button illuminates.
To reactivate, press Î again; LED
extinguishes in the button. The
system is reactivated automatically
the next time the ignition is switched
on.
Note
When the fast idle function is
activated, the stop-start system is
automatically deactivated and
cannot be reactivated by pressing
Î . LED in button illuminates to
indicate deactivation and a
corresponding message may
appear in the Driver Information Centre 3 102.
Idle speed control 3 136.
AutostopManual transmission
If the vehicle is at low speed or
standstill, activate an Autostop as
follows:
● depress the clutch pedal
● move the selector lever to neutral
● release the clutch pedal
Control indicator Ï may flash if the
clutch is not released sufficiently.Manual transmission automated
If the vehicle is at a standstill, activate an Autostop as follows:
● selector lever in position N (or
A/M )
● depress brake pedal firmly
● do not accelerate
The engine will be switched off while
the ignition stays on if the required conditions are fulfilled.
An Autostop is indicated when Ï
illuminates green in the instrument
cluster 3 100.
During an Autostop, the heating
performance, power steering and
brake performance will be
maintained. Brake assist, however, is
not available 3 156.
Note
If you exit the vehicle while the
engine is in an Autostop, a warning
chime will sound as a reminder that
the engine is on standby and has not been switched off.
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.
New vehicle running-in 3 134.
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.
Starting the engine 3 135.
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.
