Control of the vehicle
Never coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction in power steering assist and vehicle
speed is reduced.
Stop-start system 3 110.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Steering
If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.
108Driving and operatingCaution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and
engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
battery.

Driving and operating111AutostopIf the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● depress the clutch pedal
● set the lever to neutral
● release the clutch pedal
The engine will be switched off while
the ignition stays on.
An Autostop is indicated when control
indicator ^ flashes in the DIC 3 85.
During an Autostop, the heating,
power steering and brake
performance will be maintained.
Caution
The steering assist may be
reduced during an Autostop.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
Otherwise an Autostop will be
inhibited.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the driver's door is closed and the
driver's seat belt is fastened
● the battery is sufficiently charged
and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the engine exhaust temperature is not too high, e.g. after driving
with high engine load
● the ambient temperature is not too low
● the climate control system allows
an Autostop
● the self-cleaning function of the diesel particle filter is not active
● the vehicle has moved since the last Autostop
● the brake vacuum is sufficient ● the windscreen wipers are not operating at fast speed
● reverse gear is not selected
● heated rear window is not operating
Ambient temperature near to the
freezing point can inhibit an
Autostop.
For manual transmission automated vehicles, an Autostop may be
inhibited until a speed of approx.
6 mph is reached.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 108.
Battery discharge protection
To ensure reliable engine restarts,
several battery discharge protection
features are implemented as part of
the stop-start system.
112Driving and operatingRestarting the engine
Manual transmission
The selector lever must be in neutral
to enable an automatic restart.
Depress the clutch pedal to restart the
engine.
Manual transmission automated
If the lever is in position N, select
another gear, otherwise release the
brake pedal or move the lever to +, –
or R to enable an automatic restart.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart may be noticeable.
Restarting the engine with the key When one of the following conditions
occurs during an Autostop, the
engine will need to be restarted
manually using the key.
● the driver's seat belt is unfastened and the driver's door
is opened
● three minutes have elapsed since the engine was switched offIn this event, control indicator ^
flashes in the DIC in conjunction with
a warning chime. Depending on
version, a corresponding message
may also appear in the DIC 3 85.
Fault
If control indicator Æ illuminates in the
instrument cluster, there is a fault in
the stop-start system 3 84.
Depending on version, 9 will
illuminate as an alternative if control
indicator Æ is not present. A warning
message may also be displayed in
the DIC 3 85.
Generic warning 9 3 76.
Seek the assistance of a workshop.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine. Turn the ignition key to position 0 and
remove it. Turn the steering
wheel until the steering wheel
lock is felt to engage.
● If the vehicle is on a level surface or uphill slope, engage
first gear before switching off
the ignition. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before switching off the ignition. Turn the front wheels towardsthe kerb.
Lock the vehicle 3 21 and activate the
anti-theft locking system 3 26 .
130Driving and operatingTrailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Vehicles with natural gas engine may
require special towing equipment.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball bar for towing. Always keep the
coupling ball bar in the vehicle.
Driving characteristics and towing tips
Before attaching a trailer, lubricate the coupling ball. However, do not do so if a stabiliser, which acts on the
coupling ball, is being used to reduce
snaking movements.For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than
1300 kg the use of a stabiliser is
strongly recommended when driving
above 50 mph.
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 3 179.
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
3 170.
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.

Accessories and vehiclemodifications
We recommend the use of 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.
136Vehicle careEngine coolantThe coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be between the
MIN and MAX mark. Top up if the
level is low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluid
If the fluid level in the reservoir falls
below the MIN mark consult a
workshop.
If an unusual noise sounds during
steering or the power steering reacts
conspicuously, seek the assistance of
a workshop.
154Vehicle care9Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.
9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 10 mm to the tyre tread
and the inboard sides (including chain lock).
Do not exceed 30 mph when tyre
chains are fitted.
9 Warning
Damage may lead to tyre blowout.
Tyre repair kit
Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that is at tyre's sidewall cannot be repairedwith the tyre repair kit.9 Warning
Do not drive faster than 50 mph.
Do not use for a lengthy period.
Steering and handling may be
affected.
If you have a flat tyre:
Apply the parking brake and engage
first or reverse gear.
The tyre repair kit may be located
under the front seat, in the glovebox,
or on the right side of the load
compartment behind a cover.
