Regulation according to the vehicle in the adjacent lane
During regulation your vehicle may be regulated according to the vehicle in the adjacent lane.
This could occur at speeds above about 80 km / h when your vehicle is moving
faster than the vehicle in the adjacent lane on the driver's side. The display
shows the detected vehicle is in the adjacent lane.
Note
Some ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.

Operation
179
Operating conditions
179
The traffic jam assistant helps at speeds below 60 km / h to keep the vehicle within the lane while keeping the distance to the vehicle ahead.
The system is only available for vehicles with Automatic transmission.
WARNING■
Please take note of the general points relating to the use of assistance
systems » page 142, in section Introduction .■
The driver must always have hands on the steering wheel and be ready to
take over steering of the vehicle himself (accelerate or brake).
Note
The system is designed primarily for use on motorways.
Operation
Read and observe
on page 179 first.
The traffic jam assistant is an extension of the systems Lane Assist » page 174
and ACC » page 163 and works by using the functions of these two systems.
For this reason, the chapters on System Lane Assist and ACC are to be read
carefully and the safety notes are to be observed.
Operating conditions
Read and observe
on page 179 first.
The system can work when the following basic conditions are present. Lane Assist with the adaptive tracking is enabled, the boundary lines on
both sides are recognized lane » page 174.
ACC is activated and the regulation » page 163 follows.
The vehicle is travelling less than about 60 km/h.
The system activation is automatic provided that the above conditions are met and a preceding vehicle is detected. The warning light
illuminates in the in-
strument cluster.
Assistant for emergencies
Introduction

Operating conditions

179Assist systems
The assistant for emergencies (following known as system) detects inactivity
of the driver, which for example can be caused by a sudden loss of conscious-
ness. The system then performs measures as safely as possible to decelerate
the vehicle to a stop.
The system is only available for vehicles with Automatic transmission.WARNING■
Please take note of the general points relating to the use of assistance
systems » page 142, in section Introduction .■
The system is intended for emergency situations when the driver is sud-
denly unable to take over the steering task. Therefore, never try to test out
the system - there is a risk of an accident!
Operation
Read and observe
on page 180 first.
The assistant for emergencies is an extension of the systems Lane Assist
» page 174 and ACC » page 163 and works by using the functions of these two
systems.
For this reason, the chapters on System Lane Assist and ACC are to be read
carefully and the safety notes are to be observed.
System intervention
If the system detects the driver's inactivity, it draws attention to this fact by a
beep and a message on the display of the instrument cluster. It keeps the ve-
hicle in its lane.
If the driver does not take over the steering even after repeated warning, the
system begins to automatically brake the vehicle. This is followed by continu-
ous braking. After the vehicle has come to a stop, automatic activation of the
parking brake takes place.
With automatic braking, the hazard warning lights are activated to warn other
road users.
Note
The automatic braking interventions can be cancelled by pressing the acceler-
ator pedal or by steering intervention.Operating conditions
Read and observe
on page 180 first.
The system can intervene when the following basic conditions are present. Lane Assist is activated and the boundary line is detected at least on one
side of the lane » page 174.
ACC is activated and the regulation » page 163 follows.

The traffic sign recognition (following known as system) shows certain traffic
signs (e.g. speed limits) on the display of the instrument cluster and if necessa-
ry warns against excessive speeds.
WARNING■ Please take note of the general points relating to the use of assistance
systems » page 142, in section Introduction .■
Vertical traffic signs must always take precedence over the traffic signs
shown in the display. The driver is always responsible for correctly assess-
ing the traffic situation.
■
Traffic signs may not be recognised at all by the system, or may be recog-
nised incorrectly. As a result, the traffic signs may not be displayed at all, or
the wrong one may appear.
■
The speed limits shown in the road signs displayed refer to the country-
specific speed measurement units. For example, the display
may refer to
km/h or mph, i.e. specific to that country.
Note
The system is only available in some countries.180Driving

road (instead they should remain behind a crash barrier, for instance) while
the wheel is being changed.
Tyres with increased puncture resistance
Some vehicles may be fitted with tyres at the factory that have increased
puncture resistance (so-called “SEAL” tyres).
These vehicles are delivered without a puncture repair kit, spare wheel and
appropriate hand tools.
If the tyres with increased puncture resistance are replaced with tyres that
have no increased puncture resistance then the vehicle should be equipped
with a puncture repair kit, spare wheel and appropriate hand tools.
