Switch off Traffic Jam Assist in the following situations
Traffic Jam Assist should always be switched off in the following situations due to system
limitations:
• When a high level of concentration is required by the driver.
• Very sporty driving.
• In poor weather conditions, e.g. snow or heavy rain.
• Poor road conditions.
• Driving through road works.
• In urban areas.
If Traffic Jam Assist does not function as described in this chapter, do not use the system
and go to a qualified workshop.
If there is a fault in the system, visit a qualified workshop and have the system checked.
Emergency Assist
Emergency Assist detects a lack of
activity on the part of the driver and can
keep the vehicle in lane automatically,
or brake the vehicle to a standstill if
required. The system can therefore
actively help to prevent an accident.
Emergency Assist is an extension of the lane keeping system (Lane Assist)

, and combines this function with the Adaptive Cruise Control (ACC)
⇒
Adaptive Cruise Control (ACC)
. Please therefore read both these chapters and observe the
information about the system limits and warnings.
Description
If there is no driver activity, Emergency Assist prompts the driver to take control of the vehicle again
by visual and acoustic warnings and by braking jolts.
If the driver remains inactive, the system automatically controls the accelerator, brake and steering
to slow the vehicle down and keep it in lane

The intelligent technology of Traffic Jam Assist cannot overcome the laws of physics, and
functions only within the limits of the system. Always take care when using Traffic Jam
Assist as you could otherwise cause accidents or injuries. The system is not a substitute
for the full concentration of the driver.
• Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road
and traffic conditions.
• Do not use Traffic Jam Assist in urban traffic.
• Do not use Traffic Jam Assist in poor visibility, on steep or winding roads, or on
slippery road surfaces e.g. on snow, ice, wet roads, loose chippings or flooded roads.
• Never use Traffic Jam Assist off-road or on unsurfaced roads. Traffic Jam Assist is
designed solely for use on surfaced roads.
• Traffic Jam Assist does not react to persons, animals or vehicles crossing or
approaching in the same lane.
• If the speed reduction achieved by Traffic Jam Assist is insufficient, brake the vehicle
immediately by depressing the foot brake.
• If the vehicle starts to roll unintentionally after the driver has been prompted to take
control of the vehicle, brake the vehicle immediately using the foot brake.
• If a prompt instructing the
driver to take control of the vehicle
appears on the
instrument cluster display, take control of the vehicle immediately.
• Your hands should always be on the steering wheel so that you can steer at any time.
The driver is always responsible for staying in lane.
• The driver must be prepared to take control of the vehicle (by accelerating or braking)
at all times.
