r-f"n First read and observe the introductory L-W! information and safety warnings & on page 312.
Visual display in the exterior Situation mirror housing
The lane change assist system uses radar sensors to monitor the area behind the vehicle. The system then measures the distance and the difference in speed to other vehicles. The lane change assist system is activated at speeds over approximately 10 km/h (6 m ph) and deactivated at speeds under 5 km/h (3 mph). The driver receives infonmation via the visual display in the exterior mirror housing.
Visual display in the exterior mirror housing
The visual displays 248 in the exterior mirror housing notify the driver of following traffic on ei-ther side of the vehicle whenever a traffic situation is classified as critical when the driver intends to change lanes.
Tinted side windows or retrofitted tinting foils can negatively affect or distort the visual displays in the exterior mirror.

Radar sensors
The radar sensors are on the left and right behind the rear bumper and are not visible from outside. They monitor an area of approximately 70 metres behind the vehicle and the blind spots to the right and left of the vehicle. The monitored area to the side of the vehicle is approximately one lane wide.
The width of the lane is not detected in individual cases. but is predefined in the system. For this rea-son. incorrect displays could be shown when driv-

(l) System faulty. ed off and back on again and if it is not possi-ble to calibrate the tyre monitoring system, please go to a qualified workshop. Have the system checked.
•I Indicator lamp flashes for around 1 minute and then lights continuously.
Several warning and indicator lamps will light up briefly as a functional check when the lgnilion is switched on. They will go out after a few seconds.
A WARNING
Differing tyre pressures or tyre pressures that are too low can cause tyre failure, the loss of vehicle control, accidents, serious in-jury and death.
• If the Indicator lamp (l) lights up, stop the vehicle as soon as possible and check all the tyres.
• Different tyre pressures or tyre pressures that are too low can Increase wear on the tyres, reduce vehicle stability and Increase the braking distance.
• Differing tyre pressures or tyre pressures that are too low can cause sudden tyre failure and lead to a tyre burst and the loss of con-trol over the vehicle.
• The driver Is responsible for the correct tyre pressure of all tyres on the vehicle. The recommended tyre pressure can be found on the tyre pressure label 367.
• The tyre monitoring system cannot func-tion correctly until all cold wheels have the correct tyre pressure.
• The use of Incorrect tyre pressures can cause accidents and tyre damage. All tyres must always have the correct tyre pressure to suit the vehicle load.
• Always Inflate all tyres to the correct tyre pressure before every journey.
• If driven with Insufficient pressure, the tyre flexes more. This could warm up the tyre to such an extent that the tread may separate and the tyre could burst.
• High speeds and overloading of the vehi-cle may cause the tyres to heat up to such an extent that the tyre bursts, leading you to lose control of the vehicle.

A WARNING (Continued)
• If the tyre pressure Is too low or too high, the tyres will wear prematurely and the vehl-cle will not handle well.
• If the tyre Is not flat and it Is not necessary to change the wheel immediately, drive at low speed to the nearest qualified workshop and check and correct the tyre pressure.
A WARNING
Failure to observe illuminated warning lamps and text messages can lead to your vehicle breaking down In traffic, and can cause acci-dent and serious injury.
• Never ignore any illuminated warning lamps or text messages.
• Stop the vehicle as soon as possible and when safe to do so.

.........r'n First read and observe the Introductory L-.lr:.ll Information and safety warnings & on page 322.
The cooling system for the vehicle interior only works when the engine is running and the blower is switched on.
The air conditioning system operates most effec-tively with the windows and the sliding/tilting roof closed. However, if the vehicle has heated up after standing in the sun for some time, the air inside can be cooled more quickly by opening the win-dows and the sliding/tilting roof for a short time.
Settings for optimal road visibility
Switching the cooling system on not only reduces the temperature of the vehicle interior, but also the humidity. This improves comfort for the vehicle oc-cupants and prevents the windows from misting when the outside humidity is high.
Climatic
• Switch off air recirculation mode 330.
• Set the blowers to the required level.
• Set the temperature to +22•c (+72.F).
• Open and position all vents on the dash panel 329.
• Turn the air distribution controller to the desired position.
• Press the@) button to switch the cooling sys-tem on. The indicator lamp in the button lights up.

Cllmatronlc
• Press button.
• Set the temperature to +22•c (+72.F).
• Open and position all vents on the dash panel 329.
The cooling system cannot be switched on
The following criteria may prevent the cooling sys-tem from being switched on:
• The engine is not running.
• The blower is switched off.
• The air conditioning system fuse has blown.
• The ambient temperature is lower than approxi-mately +3"C (+38°F).
• The compressor has been temporarily switched off because the coolant temperature is too high.
• There is a different fault in the vehicle. The air conditioning system should be checked by a quali-fied workshop.
Things to note
If the humidity and temperature outside the vehicle are high, condensation can drip off the evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does not indicate a
