The towing eye may be used to pull the car up onto a recovery vehicle with a flatbed platform.The car's position and ground clearance deter-mine whether it is possible. If the slope of the recovery vehicle's ramp is too steep, or if the ground clearance under the car isinadequate, then the car may be damaged if youtry to pull it up using the towing eye. If necessary, raise the car by using the recovery vehicle's lifting device. Do not use the towing eye.
WARNING
No one/nothing is allowed to remain behind the recovery vehicle while the car pulled uponto the flatbed platform.
IMPORTANT
The towing eye is only designed for towing on roads -
not for pulling the car unstuck or out
of a ditch. Call a recovery service for recovery assistance.

Factors affecting the network.
The amount of data transferred is dependent on the services or apps in use in the car. For exam-ple, streaming audio can require large amounts ofdata which requires a good connection and goodsignal strength.
Mobile phone to carThe speed of the connection may vary dependingon the location of the mobile phone in the car.Move the mobile phone handset closer to thecentre display in order to increase the signalstrength. Ensure that there is no source of inter-ference in between.
Mobile phone to networkThe speed of the mobile network varies depend-ing on the coverage in the present location. Poornetwork coverage may occur, for example in tun-nels, in mountainous country, in deep valleys orindoors. The speed also depends on the agree-ment you have with your network.
NOTE
In the event of problems with data traffic, con- tact your network operator.
6 This does not apply in the case of connection with Wi-Fi.
