Manoeuvring the vehicle
To manoeuvre the vehicle back and forth
during attempts to park or in garage
entrances the creeping movement can be
utilised by releasing the foot brake.
Never actuate accelerator and brake
pedals simultaneously.
To prevent damage, the manual
transmission automated deactivates the
"creep function" when the temperature of
the automatic clutch is extremely high. Vehicle storage
Apply the handbrake and remove the key
from the ignition. The most recently
engaged gear (indicator in transmission
display) remains engaged. With
N, no gear
is engaged.
When the ignition is switched off the
manual transmission automated no longer
responds to movement of the selector
lever.
Lock the vehicle. Otherwise the battery
may become discharged if the vehicle is
parked for long periods.
If the hand brake has not been applied, the
control indicator R flashes for a few
seconds after the ignition is switched off.
With the engine off and the hand brake not
applied, when the driver ’s door is opened a
warning buzzer sounds and the control
indicator R flashes; switch on ignition,
engage gear, switch off ignition and apply
hand brake.

Fault
To prevent damage to the automated
manual transmission, the clutch is closed
automatically at high clutch temperatures.
Warning light A lights up in the event of a
fault. Continued driving is possible, but
manual mode can no longer be used for
changing gear.
If "F" also appears in the transmission
display, continued driving is not possible.
Have cause of fault remedied by a
workshop. The system’s integrated self
diagnostics allow faults to be quickly
remedied.

Interruption of power supply
The clutch is not disengaged if there is an
interruption of the power supply when a
gear is engaged. The vehicle cannot move.
If the battery is flat, start the car using
jump leads 3191. If the cause of the power supply
interruption is not a flat battery, contact a
workshop for assistance. If the vehicle has
to be moved out of flowing traffic,
disengage clutch as follows:
1. Apply hand brake and switch off
ignition.
2. Open bonnet and engage support.
3. Clean transmission around the cap (see Fig.) so that no dirt can get into
the opening when the cap is removed.
4. Rotate cap to slacken and remove by lifting upwards – see figure.
5. Turn the adjusting screw clockwise using a flathead screwdriver (vehicle
tools 3 3198) until clear resistance can
be felt. The clutch has now been
disengaged. 6. Fit cleaned cap again. The cap must be
in full contact with the housing.
Contact a workshop for assistance
immediately.
Caution
Do not turn any further after feeling
resistance, since this can damage the
manual transmission automated.
Caution
Towing the vehicle and starting the
engine is not permitted when the clutch
has been released in this way, although
the vehicle can be moved a short dis-
tance.

150 Driving and operationSave energy – more kilometres
Please observe the running-in hints on the
previous page and the tips for saving
energy on the following pages.
Good, technically correct and economical
driving ensures maximum durability and
performance for your vehicle.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, e.g. when the vehicle is
driven with a gear engaged but no throttle
application. Overrun cut-off is deactivated
if catalytic converter temperature is high.
Vehicles with turbocharged engine Flow-generated noises may be audible if
the accelerator is released quickly on
account of air flow in the turbocharger.
Engine speed
Drive in a low engine speed range for each
gear as much as possible. Warming up
After a cold start, the automatic
transmission
3 or manual transmission
automated 3 in automatic mode shifts into
higher gears at higher rpm. This allows the
catalytic converter to quickly reach the
temperature required for optimum pollutant
reduction.
Correct gear selection
Do not race your engine whilst in neutral or
with a low gear selected. Driving too fast in
individual gears as well as stop-and-go
traffic increases engine wear and fuel
consumption.
Change down
When decreasing speed, shift down into
the next lowest gear. Do not slip the clutch
with a high-revving engine. This is
especially important when hill climbing. Cooling fan
The cooling fan is controlled via a
thermoswitch and therefore only runs if
necessary.
The cooling fan automatically switches on
when the diesel particle filter is being
cleaned
3 depending on the engine.
Pedals
Do not place any objects in the foot well
which could slip under the pedals and
inhibit the pedal travel.
To ensure the pedal travel is uninhibited,
there must be no mats in the area of the
pedals.
Battery care
When driving slowly or when the vehicle is
stationary, e.g. in slow urban traffic, stop-
and-go traffic or traffic jams, turn off all
unnecessary electrical loads where
possible (e.g. heated rear window, heated
front seats, etc.).
Declutch when starting in order to relieve
the strain on the starter and the battery.

Hydraulic brake system The foot brake comprises two independent
brake circuits.
If a brake circuit fails, the vehicle can still be
braked using the other brake circuit.
However, the brake pedal must be
depressed a considerable way before any
braking effect occurs, and much more
force is required. The braking distance is
longer. Contact a workshop for assistance
before continuing to drive. To ensure that full
pedal travel can be
utilised, especially in case of a fault in one
of the brake circuits, there must be no mats
in the vicinity of the pedals 3150.
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. This is especially important
to bear in mind when towing.
The brake fluid level should be checked
regularly. If the brake fluid level is too low
and the hand brake is not applied, control
indicator R on the instrument panel
illuminates 389.
Picture no: 18257s.tif
Brake system control indicator R
The control indicator lights up when the
ignition is switched on when the hand
brake is applied or when the brake or
clutch fluid level is too low. Brake fluid
level 3246.
For vehicles with manual transmission
automated 3, the control indicator flashes
for a few seconds when the ignition is
turned off when the hand brake is not
applied.

Warning
If the control indicator illuminates when
the hand brake is released, stop driving
immediately. Contact a workshop for
assistance.
