Driving and operating139Parking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.
Control indicator R 3 88.
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 prevent unintended movement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further 2 seconds. The brakes release automatically as soon
as the vehicle begins to accelerate.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.
When ESP® Plus
comes into action v
flashes.

when driving.
Adapt speed to the road
conditions.

Deactivation
ESP® Plus
can be deactivated when
Sport mode is engaged for high-
performance driving:
Hold the SPORT button depressed
for about 4 seconds. Control indicator v illuminates. ESPoff also appears in
the service display.9 Warning
Do not deactivate ESP® Plus
if a
run-flat tyre has lost pressure.
ESP® Plus
is reactivated by pressing
the SPORT button. ESPon appears in
the service display. ESP® Plus
is also
reactivated the next time the ignition is switched on.

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.

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 operating147
For trailers with low driving stability
and trailers with a permitted gross
vehicle weight of more than 1300 kg a speed of 50 mph must not be
exceeded; the use of a stabiliser is
recommended.
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 3 205.
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 due to 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
3 196.
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 62 mph applies.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.

modifications
We recommend using genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
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.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve rubber seals.
■ Fill up fuel tank completely.
■ Change engine oil.
■ Drain washer fluid reservoir.
■ Check coolant antifreeze.
■ Adjust tyre pressure to the value specified for full load.
■ 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 parking brake.

152Vehicle care
■ Open bonnet, close all doors andlock 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 electronics of the
power windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir.
■ Check the engine oil level.
■ Check the coolant level.
■ Fit the number plate if necessary.End-of-life vehicle
