The integrated Rear Traffic Alert provides assistance when reversing out of a parking space and
manoeuvring.
System limits
Use the lane keeping system only on paved roads.
The lane change system may interpret the traffic situation incorrectly in the following driving
situations, for example:
•In tight bends.
•When driving in the middle of two lanes.
•When road lanes are of varying width.
•At the brow of a hill.
•In poor weather conditions.
•Where there are special roadside structures, e.g. high or offset crash barriers.
You can save some settings in the user accounts of the personalisation function
⇒ Personalisation.
Driving with the lane change system
Fig. 148 In the exterior mirror housing: visual displays for the lane change system.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Switching on and off
•By means of the Assist systems menu in the instrument cluster ⇒ Instrument cluster
operation.
•OR: depending on the vehicle equipment, by means of the button for the driver assist systems
⇒ Button for driver assist systems.
•OR: depending on the vehicle equipment, in the Driver assistance menu in the Infotainment
system ⇒ Operation and display in the Infotainment system.
When the lane change system is switched on, the yellow indicator lamp in the exterior mirror
housing lights up once briefly ⇒ Fig. 148.
This most recent system setting is retained even after the ignition has been switched off and on.
Function
When switched on, the lane change system is active from a speed of around 15 km/h (9 mph). The
lane change system is deactivated at a vehicle speed below 10 km/h (6 mph).
The intelligent technology of the lane change system including Rear Traffic Alert cannot
overcome the laws of physics, and functions only within the limits of the system. Never let
the extra convenience afforded by the lane change system including Rear Traffic Alert
tempt you into taking any risks when driving. Always take care when using the lane
change system and the Rear Traffic Alert 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.
•Your hands should always be on the steering wheel so that you can steer at any time.
•Pay attention to the visual displays in the exterior mirror housing and in the instrument
cluster display, and respond to the commands.
•Always pay close attention to what is happening around the vehicle.
•Never use the lane change system including Rear Traffic Alert if the radar sensors are
dirty, covered or damaged. These circumstances can impair the proper functioning of
the system.
•It may be hard to see the display in the exterior mirror in direct sunlight.
WARNING
Red and green frames: vehicle outline (mode 2).
Trailer support (mode 3)
In vehicles with a factory-fitted towing bracket, the trailer support function can be used when
approaching a trailer drawbar. The powerful zoom level used in this mode means that obstacles
behind the vehicle appear very late.
Auxiliary lines are shown on the Infotainment system.
Red line: position of the towing bracket.
Green lines: distance to towing bracket. The distance intervals are around 0.1 m in each case.
Orange line: predicted path of the towing bracket, depending on the steering angle.
Crossing traffic (mode 4)
This display representation helps the driver to monitor traffic behind the vehicle and can be used in
situations such as driving out of a garage or narrow exits, for example.
Prerequisites
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The following prerequisites must be met for detection of a parking space:
•Do not exceed a speed of approximately 15 km/h (9 mph).
•Width of the parking space: vehicle width + 0.2 m.
•Distance: position the vehicle approximately one metre from the parking space (mode 2 only).
•Length of the parking space: approx. 8 m (mode 2 only).
The following conditions must be met in order to display a correct image:
•The boot lid is closed.
•The surrounding area has a flat surface.
•Vehicle does not have a heavy load at the rear.
Parking perpendicular to the road (mode 1)

Driving into a parking space
•Press the or button before driving past the selected parking space.
•With the rear view camera system switched on and operational, select mode 1 .
•Position the vehicle in front of the parking space ⇒ Fig. 155②.
•Steer so that the yellow lines ③ lead into the parking space . The green and yellow lines
must be aligned with the side limit lines ③.

In the example there are 4 plies under the tread surface:
1 ply of rayon (artificial silk), 2 steel belt plies and 1 nylon
ply.
The tyre lettering is located on both sides. Certain labels may only be found on one side of the tyre,
e.g. tyre identification number and manufacturing date.
Any further numbers and letters are internal codes used by the tyre manufacturer or
country-specific denotations.
Low-profile tyres
Low-profile tyres have a wider tread surface, larger rim diameter and lower side walls than
conventional wheel/tyre combinations ⇒. Low-profile tyres can improve the vehicle's handling
and precision. They may however result in a less comfortable ride on uneven road surfaces and
tracks.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with directional tread. The
direction of rotation must be observed in all cases. This guarantees the best possible running
characteristics.
If, however, the tyre is fitted in the opposite direction to the tread pattern, you must take more care
when driving as the tyre is now no longer being used according to its designation. The tyres must
be replaced as quickly as possible or be fitted with the tread in the correct direction.
Asymmetrical tyres
Asymmetrical tyres take into account the differing behaviour of the inner and outer areas of the
tread pattern. The sidewalls of asymmetrical tyres are marked to indicate "inside" or "outside".
Maintain the correct tyre positioning on the wheel rim.
Tyre load
The load capacity index indicates how many kilograms can be loaded onto an individual tyre (tyre
load).

Type plate
The type plate ⇒ Fig. 253 can be seen on the lower part of the door pillar when the door is
open. Vehicles for certain export countries do not have a type plate.
The type plate contains the following data:
Permit
Gross vehicle weight rating
Gross combination weight rating (vehicle plus trailer ⇒ Trailer towing)
Gross axle weight rating, front
Gross axle weight rating, rear
Vehicle identification number
The vehicle identification number can be read from outside the vehicle through a viewer in the
windscreen ⇒ Fig. 254 (arrow). The viewer is located in the lower corner of the windscreen. The
vehicle identification number is also stamped on the right-hand water drainage channel. The water
drainage channel is located between the suspension turret and wing. Open the bonnet ⇒ In the
engine compartment to gain access to the vehicle identification number.
Dimensions

The data in the table apply to the most basic German model.
The specified values can vary due to different tyre and wheel sizes, if additional equipment is fitted,
for different equipment packages, for retrofitted accessories, and for special vehicles. They can also
vary in vehicles that have been manufactured for other countries.
