Kickdown If the accelerator pedal is pressed
past the pressure point, the
transmission shifts to a lower gear
depending on engine speed.
Fault
In
the event of a fault, A illuminates.
The transmission no longer shifts
automatically. Continued travel is
possible with manual shifting.
Have the cause of the fault remedied
by a workshop. Version without manual mode
2nd gear is not available. Manual
shifting:

Version with manual mode
Only the highest gear is available.
Depending
on the fault, 2nd gear may
also be available in manual mode.
Interruption of power
supply
In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P or N
position.
If the battery is discharged, start the
vehicle using jump leads 3 185.
If the battery is not the cause of the
fault, release selector lever: 1. Apply hand brake. 2. Remove ashtray insert

Activation
Press the T button. The transmission
switches to automatic mode. The
vehicle starts off in 2nd gear. Sport
mode is deactivated.
Deactivation
The Winter programme is switched off
by:
■ pressing the T button again
■ turning off the ignition,
■ switching to manual mode (when switched back to automatic mode,
the Winter programme is again
active)
■ when clutch temperature is too high Kickdown
If the accelerator pedal is pressed
past the pressure point, 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.
A illuminates in the event of a fault.
Continued driving is possible. Manual
mode cannot be used for shifting. If F appears in the transmission
display, continued driving is not
possible.
Have the cause of the fault remedied
by a workshop.
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 discharged, start the
vehicle using jump leads 3 185.
If the cause of the fault is not
a discharged battery, seek the
assistance of a workshop.

Driving and operating
141
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 though
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 89.
Adaptive brake lamp
During full braking, all three brake
lamps flash for the duration of ABS
control. Fault
9
Warning 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
Always apply hand brake firmly
without operating the release button,
and apply as firmly as possible on
a downhill or uphill slope.
To release the hand brake, pull the
lever up slightly, press the release
button and fully lower the lever.
To
reduce the operating forces of the
hand brake, depress the foot brake at
the same time.

Driving and operating
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 pull away on
inclines. After releasing the brake
pedal, if the hand brake is not applied
the brakes are released after a 2-
second delay. Ride control systems
Electronic stability
program
Electronic stability program
(ESP®
Plus
) improves driving stability
when necessary, regardless of the
type
of road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP® Plus
is operational as soon as
control indicator v extinguishes.

Interactive driving system
Interactive driving system (IDS Plus

combines the electronic stability
program (ESP® Plus
) with the antilock
brake system (ABS) and continuous
damping control (CDC) to improve
driving dynamics and vehicle safety. Sport mode
Suspension and steering become
more direct and provide better
contact with the road surface. The
engine reacts more quickly to
accelerator pedal movements.
Automatic
gear changing is also more
responsive.

Driving and operating
The fuel filler cap can be retained in
the bracket on the fuel filler flap. Caution
Wipe off any overflowing fuel
immediately.
Natural gas refuelling
When filling with natural gas, remove
the
protective cap from the filler neck. 9
Warning Refuel only with a maximum
output pressure of 250 bar. Use
only temperature compensated
filling stations.
The refuelling procedure must be
completed,
i.e. the filler neck must be
vented. Refit the protective cap.
The capacity of the natural gas tank
depends on outside temperature,
filling pressure and type of refuelling
system.

Driving and operating
If the trailer starts snaking, drive more
slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 220.
Trailer towing
Trailer loads
The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified
in the vehicle documents. In
general, they are valid for gradients
up to max. 12 % The permitted trailer load applies up
to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases because of the
air becoming thinner, therefore
reducing climbing ability, the
permissible gross train weight also
decreases by 10 % for every 1000
metres of additional altitude. The
gross
train weight does not have to be
reduced when driving on roads with
slight inclines (less than 8 %, e. g.
motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 208.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (75 kg) is specified on
the towing equipment identification
plate and in the vehicle documents. Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by 90
kg
and the gross vehicle weight rating
by 75 kg. If the permissible rear axle
load is exceeded, a maximum speed
of 100 km/h applies.
Towing equipment Caution
When operating without a trailer,
remove the coupling ball bar.

Vehicle storage
Storage for a long period of time
Following must be done if the vehicle
should be stored for several months:
■ Wash and wax the vehicle.

■ Park vehicle in dry, well ventilated place. Engage first or reverse gear
or set selector lever to P. Prevent
the vehicle from rolling.
■ Do not apply hand brake.
■ Open bonnet, close all doors and lock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are
not functional, e.g. anti-theft alarm
system.
Putting back into operation
Following must be done if the vehicle
is putting back into operation: ■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronic of the power
windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir.
