Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
■ The stop-start system is not manually deactivated
■ the bonnet is fully closed
■ the driver's door is closed or the driver's seat belt is fastened
■ the vehicle 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 above -5° C
■ the climate control system allows an Autostop
■ the brake vacuum is sufficient
■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle was driven at least at walking speed since the last
AutostopOtherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 154.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 161.
Vehicle battery discharge protection
To ensure reliable engine restarts, several battery discharge protection
features are implemented as part of
the stop-start system.
Power saving measures
During an Autostop, several electric
features, e.g. auxiliary electric heater
or rear window heating are disabled
or switched into a power saving
mode. The fan speed of the climate
control system is reduced to save
power.Restart of the engine by the
driver
Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.
If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a symbol in the Driver
Information Centre.
Control indicator - 3 114.
Restart of the engine by the
stop-start system The selector lever has to 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:
■ The stop-start system is manually deactivated
■ the bonnet is opened
■ the driver's seat belt is unfastened and the driver's door is opened

Driving and operating173
Electric parking brake
Applying when vehicle is stationary
Pull switch m for approx.
one second, the electric parking
brake operates automatically with an adequate force. For maximum force,
e.g. parking with trailer or on inclines,
pull switch m twice.
The electric parking brake is applied
when control indicator m illuminates
3 115.
The electric parking brake can always
be activated, even if the ignition is off.
Do not operate electric parking brake
system too often without engine
running because this will discharge
the vehicle battery.
Before leaving the vehicle, check the
electric parking brake status. Control
indicator m 3 115.
Releasing
Switch on ignition. Keep brake pedal
depressed and then push switch m.
Drive away function
Depressing clutch pedal (manual
transmission) or engaging drive gear
(automatic transmission) and then
depressing the accelerator pedal
releases the electric parking brake
automatically. This is not possible
when the switch is pulled at the same
time.
This function also helps driving away
on inclines.
Aggressive drive away may reduce life time of wear parts.Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electric
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Fault
Failure mode of electric parking brake
is indicated by control indicator j and
by a code number or a vehicle message which is displayed in the
Driver Information Centre. Vehicle
messages 3 126.
Apply electric parking brake: pull and
hold the switch m for more than
5 seconds. If control indicator m
illuminates, electric parking brake is
applied.
Release electric parking brake: push
and hold the switch m for more than
2 seconds. If control indicator m
extinguishes, electric parking brake is released.

210Driving and operating
Pressing the LPG button switches
between petrol and liquid gas
operation as soon as the required
parameters (coolant temperature,
gas temperature and minimum
engine speed) have been reached.
The requirements are usually fulfilled
after around 60 seconds (depending
on exterior temperature) and the first
firm press on the accelerator. The
LED status shows the current
operating mode.1 off=petrol operation1 illumi‐
nates=liquid gas operation1 flashes=no switching is
possible, one type
of fuel is empty
As soon as the liquid gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
Every six months, run the petrol tank
down until control indicator i
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
■ Is there enough liquid gas present?
■ Is there enough petrol present for starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If possible, close the manual shut-off
valve on the multivalve. The
multivalve is located on the liquid gas
tank in the load compartment,
underneath the rear floor cover.

Tyre pressure 3 306 and on the label
on the front left or right door frame.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the body style.
2. Identify the engine identifier code.
Engine data 3 289.
3. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 306.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre pressure monitoring system The tyre pressure monitoring system
checks the pressure of all four wheels
once a minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
