Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the driver
Vehicles with manual transmission
Depress the clutch pedal without
depressing the brake pedal to restart the engine.
Vehicles with automatic transmission Type A: The engine is restarted if
● the gear selector is in position D
with M activated or not and the
brake pedal is released● the gear selector is in position N,
the brake pedal is released and
the gear selector is moved to
position D with M activated or not
● the gear selector is in position P,
the brake pedal is depressed and the gear selector is moved to
position R, N or D with M
activated or not
● the reverse gear is engaged
Type B: The engine is restarted if ● the gear selector is in position A
or M and the brake pedal is
released
● the gear selector is in position N,
the brake pedal is depressed and and the gear selector is moved toA or M
● the reverse gear is engaged
Restart of the engine by the stop- start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically by the stop-start system:● depending on engine, vehicle speed exceeding 0.6 mph or
15 mph(manual transmission)
● vehicle speed exceeding 0.6 mph (automatic
transmission)
● stop-start system manually deactivated
● driver's door opened
● sliding door opened.
● driver's seat belt unfastened
● engine temperature too low
● charging level of vehicle battery below defined level
● brake vacuum not sufficient
● vehicle driven at least at walking speed
● climate control system requests engine start
● air conditioning manually switched on
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart might be noticeable.
206Driving and operatingBy driving uphill, the temperature of
the coolant is increased. To reduce
heating, drive at a reduced speed and
pay attention to the coolant
temperature. If the control indicator
2 of the engine coolant temperature
gauge illuminates, stop the vehicle
and switch off engine as soon as
possible.
Trailer towing Trailer loadsThe 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 12%.
The permissible trailer load applies
up to the specified incline and at sea
level. Since engine power decreases
as altitude increases due to the airbecoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of 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
3 264.
When distributing the loads in the
trailer, heavy objects should be
placed as close as possible to the
axle.
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 is specified on the
towing equipment identification plate
and in the vehicle documents.Always aim for the maximum vertical
coupling 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
60 kg , the gross vehicle weight rating
must not be exceeded. If the
permissible rear axle load is
exceeded, a maximum speed of
60 mph applies.
Towing equipment Depending on version the vehicle canbe fitted with a detachable or a fixed
coupling ball bar.
Type ACaution
When operating without a trailer,
remove the coupling ball bar.
Vehicle care217When the vehicle battery is being
replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap,
and the ventilation in the vicinity of the negative terminal must be opened.
Ensure that the battery is always replaced by the same type of battery.
The vehicle battery has to be
replaced by a workshop.
Stop-start system 3 156.
Charging the vehicle battery9 Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed 14.6 V
when using a battery charger.
Otherwise the vehicle battery may be damaged.
Jump starting 3 249.
Discharge protection
Battery voltage
When the vehicle battery voltage is
running low, a warning message will
appear in the Driver Information
Centre.
When the vehicle is being driven, the
load reduction function temporarily
deactivates certain functions, such as
the air conditioning, the heated rear
window, heated steering wheel, etc.
The deactivated functions are
reactivated automatically as soon as
conditions permit.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must
be increased. This will be achieved by
an idle boost which may be audible.
A message appears in the Driver
Information Centre.
Power outlet
The power outlets are deactivated in
the event of low vehicle battery
voltage.Warning label
Meaning of symbols:
● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
