Important information on
operation and traffic safety
9 Warning
The Infotainment system must be
used so that the vehicle can be
driven safely at all times. If in
doubt, stop the vehicle and
operate the Infotainment system
while the vehicle is stationary.
Radio reception
Radio reception may be disrupted by
static, noise, distortion or loss of
reception due to:
● changes in distance from the transmitter
● multi-path reception due to reflection
● shadowing
Theft-deterrent feature The Infotainment system is equipped
with an electronic security system for the purpose of theft-deterrence.
The Infotainment system therefore functions only in your vehicle and is
worthless to a thief.
