Anti-theft locking system9 Warning
Do not use the system if there are
people in the vehicle! The doorscannot be unlocked from the
inside.
The system deadlocks all the doors. All doors must be closed otherwise
the system cannot be activated.
Unlocking the vehicle disables the
mechanical anti-theft locking system.
This is not possible with the central
locking button.
Activating
Press e on the electronic key twice
within five seconds.
Anti-theft alarm system
The anti-theft alarm system is
combined with the anti-theft locking
system.
It monitors: ● doors, tailgate, bonnet
● passenger compartment including adjoining load
compartment
● vehicle inclination, e.g. if it is raised
● ignition
Activation
All doors must be closed and the
electronic key of the electronic key
system must not remain in the
vehicle. Otherwise the system cannot be activated.
● self-activated 30 seconds after locking the vehicle by pressingthe button on any exterior door
handle.
Keys, doors and windows35●directly by pressing e twice within
five seconds.
● with passive locking enabled: briefly activated after passive
locking occurs.
Note
Changes to the vehicle interior such
as the use of seat covers, and open
windows or sunroof, could impair the
function of passenger compartment
monitoring.
Activation without monitoring of
passenger compartment and
vehicle inclinationSwitch off the monitoring of
passenger compartment and vehicle
inclination when animals are being
left in the vehicle, because of high
volume ultrasonic signals or
movements triggering the alarm. Also switch off when the vehicle is on a
ferry or train.
1. Close tailgate, bonnet, windows and sunroof.
2. Press o. LED in the button o
illuminates for a maximum of
ten minutes.
3. Close doors.

on top of the instrument panel.
Status during the first 30 seconds of
anti-theft alarm system activation:
LED illuminates:test, arming delayLED flashes
quickly:doors, tailgate or

Position9 Warning
Only drive with the head restraint
set to the proper position.
The upper edge of the head restraint
should be at upper head level. If this
is not possible for extremely tall
people, set to highest position, and
set to lowest position for small people.
Seats, restraints71Pedestrian protection
system
Active bonnet
Pedestrian protection system can help to reduce the injury of
pedestrians in case of a front
collision.
When the sensors in the front bumper
detect a certain impact within the
speed range of 25 km/h to 50 km/h, the rear part of the bonnet will be lifted
to reduce pedestrians head injuries.
In addition the front bumper is
designed to reduce leg injuries of
pedestrians.
The active bonnet can be triggered
only once and remains in the raised
position. A message is displayed in
the Driver Information Centre.
Seek the assistance of a workshop as soon as possible, thereby adapting
the driving style, to have the
actuators, hinges and bonnet
replaced.9 Warning
Do not drive with the bonnet
raised.
9 Warning
After any frontal accident the front
bumper may appear to be intact,
however, the sensors may be
damaged. Consult a workshop to
verify proper functionality of the
sensors.
The system may not trigger under the following conditions:
● The impact is out of sensor range.
● The sensors are damaged or blocked by accessory parts.
● The bonnet is blocked by snow or
ice.
● The vehicle speed is not within the range.
● The object is too small.
Manually bonnet lowering9 Warning
After the system has triggered, the
hinges of the bonnet are hot. Do
not touch.
To manually lower the triggered
bonnet for driving to the next
workshop:
1. Pull the bonnet release lever.
2. Push the safety catch to left vehicle side.
3. Open the bonnet approx. 20 cm and lower it slowly without
engaging.
4. Push down bonnet with both hands at rear corners in small
steps alternating between right
and left side.
9 Warning
Be sure to keep away from the
edge of the bonnet to prevent
injuries.
72Seats, restraints5.Check that the bonnet is engaged
at the rear.
6. Close bonnet at the front and check that it is engaged 3 241.
168Driving and operatingDuring an Autostop, the heating and
brake performance will be
maintained.
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
Autostop.
Otherwise an Autostop will be
inhibited.
The stop-start system will be
deactivated on inclines of 12% or
more.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 150.
Immediately after motorway driving,
an Autostop may be inhibited.
New vehicle running-in 3 163.
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 electrical
features e.g. auxiliary electric heater
or heated rear window are disabled orswitched 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 transmissionConventional restart
All engines have conventional restart.
Depress the clutch pedal without
depressing the brake pedal to restart
the engine.
On engines with late restart a
conventional restart is only possible
without depressed brake pedal.Late restart
All engines have late restart in
addition to conventional restart. Late
restart is only active on gradients up
to 5%.
● Depress the brake pedal.
● Depress the clutch pedal.
● Select first gear.
● Release the brake pedal to restart the engine.
Driving and operating169Vehicles with automatic transmissionRelease the brake pedal or move
selector lever out of D into N or P to
restart the engine.
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:
● 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.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.● The climate control systemrequests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a warning message is displayed in the
Driver Information Centre.
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.
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 the parking brake. Pull switch m for
approx. one second and check
if the control indicator m
illuminates.
The electric parking brake is applied when control indicator
m illuminates 3 109.
● Switch off the engine. ● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position P before
switching off ignition. On an
uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position P before switching off ignition.
Turn the front wheels towards
the kerb.
● Close the windows and the sunroof.
● Switch off ignition with power button. Turn the steering wheel
until the steering wheel lock is
felt to engage.
