156Driver assistance systems
Note
If the City Safety Assist function activates a brake, the brake pedal range is
reduced. This makes the brake pedal seem “harder”.
Note
Automatic brake intervention by the City Safety Assist function can be can-
celled by pressing the clutch pedal, the accelerator pedal or by a corrective
intervention.
Note
During the automatic braking by the City Safety Assist function you may
hear unusual noises. This is normal and is produced in the brakes system. 
Warning and control lamps
The City Safety Assist function is switched on every time the ignition is
switched on. No special indication is produced.
If the City Safety Assist function is switched off, functions or there is an error
in the system, this will be shown by a control lamp on the instrument panel
display.

switch off after a few seconds.
WARNING
If the warning lamps are ignored, the vehicle may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle safely as soon as possible.
CAUTION
Failure to heed the warning lamps when they appear may result in faults in
the vehicle. 

Driver assistance systems
Special driving situations

ahead out of range of the laser sensor
Fig. 100 Other vehicles
changing lanes
The City Safety Assist function has physical limits, and has limits deter-
mined by the system itself. In certain circumstances, this may produce reac-
tions from the City Safety Assist system, that are late or unexpected by the
driver. For this reason, always pay due attention and if necessary, intervene. For example, the following driving situations require special attention:
Driving through a bend
When entering or leaving a “long” bend, the vehicle may decelerate when
the laser sensor detects a vehicle travelling in the opposite lane
⇒ Fig. 99 A.
To interrupt the deceleration you can accelerate, turn the steering wheel or
press the clutch.
Narrow vehicles in front
The laser sensor will only detect narrow vehicles in front if they are in the
sensor detection zone ⇒ Fig. 99 B. This applies especially to narrow vehi-
cles such as motorbikes.
Other vehicles changing lanes
Vehicles changing lane in close proximity can cause an unexpected brake
from the City Safety Assist system ⇒ Fig. 100. To interrupt the deceleration
you can accelerate, turn the steering wheel or press the clutch. 

workshop.
Some warning and control lamps will light up briefly when the ignition is
switched on to check certain functions. They will switch off after a few sec-
onds.
WARNING
If the warning lamps are ignored when they light up, the vehicle may
stall in traffic and cause accidents and severe injuries.
● Never ignore the warning lamps.
● Stop the vehicle at the next opportunity.
CAUTION
Failure to heed the control lamps when they light up may result in damage
to the vehicle. Start-Stop system
Fig. 101 At the top of
the centre console: Start-
Stop system button
With the Start-Stop system enabled, the engine is automatically stopped
when the vehicle is at a standstill. It will start again automatically as re-
quired.
This function remains enabled while the ignition is switched on. The instru-
ment panel display shows information on the current status ⇒ page 160.
Disconnect the Start-Stop system by hand whenever crossing water.
Vehicles with a manual gearbox
● When the vehicle is stopped, put it into neutral and release the clutch
pedal. The engine will stop.
● To restart, simply engage the clutch. 

Practical information
Instructions for tow starting
In general, the vehicle should not be started by towing. Jump-starting is
much more preferable ⇒  page 273.
For technical reasons, the following vehicles can not be tow started:
● Vehicles with an automatic gearbox.
● If the vehicle battery is flat, it is possible that the engine control unit
does not operate correctly.
However, if your vehicle must absolutely be tow-started (manual gearbox):
● Engage the 2nd or 3rd gear.
● Keep the clutch pressed down.
● Switch on the ignition and the hazard warning lights.
● Release the clutch when both vehicles are moving.
● As soon as the engine starts, press the clutch and move the gear lever
into neutral. This helps to prevent a collision with the towing vehicle.
CAUTION
When tow-starting, fuel could enter the catalytic converter and damage it. 
Notes on towing
Tow rope or tow bar
When towing, the tow bar is the safest and vehicle friendly way. You should
only use a tow rope if you do not have a tow bar.
A tow rope should be slightly elastic to avoid damage to both vehicles. It is
advisable to use a tow rope made of synthetic fibre or similarly elastic mate-
rial. Only secure the tow rope or tow bar to the tow ring or specially designed
fitting.
Towing vehicles with an automatic gearbox
Note the following for a towed vehicle:
●
Make sure the gear selector lever is in the N position.
● Do not drive faster than 50 km/h (30 mph) when towing a vehicle.
● Do not tow further than 50 km (30 miles).
● If a breakdown truck is used, the vehicle must be towed with the front
wheels raised.
Situations in which the vehicle should not be towed
In the following cases, the vehicle should not be towed but transported on a
trailer or special vehicle:
● If the vehicle gearbox does not contain lubricant due to a fault.
● If the battery is flat as the steering cannot be unlocked, as a result, the
electronic steering lock and electronic parking brake cannot be disengaged.
● If the vehicle to be towed has an automatic gearbox and the distance to
be covered is greater than 50 km (30 miles).
Note
The vehicle can only be towed if the steering lock electronic gearbox lock is
deactivated. If the vehicle has no power supply or there is an electric system
fault, the engine must be started using jump leads to deactivate the steer-
ing column electronic gearbox lock. 
