Telephone, general
See separate instruction manual for instructions on how 
to operate the telephone.
1 Observe the legal requirements in all countries concerned.
Wa r n i n g !
Your concentration on the road and traffic 
conditions must take priority. Only use the 
telephone
1 when road and traffic conditions 
permit. 
Park if you wish to use the handset rather than the 
hands-free device to make a call.Bear in mind that at a speed of just 30 mph 
(approximately 50 km/h), your vehicle is covering 
a distance of approximately 50 feet (approximately 
14 m )  e v e r y  s e c o n d .  
Never operate radio transmitters equipped with a 
built-in or attached antenna (i.e. without being 
connected to an external antenna) from inside the 
vehicle while the engine is running. Doing so could 
lead to a malfunction of the vehicle’s electronic 
system, possibly resulting in an accident and 
personal injury.

from the steering lock and turn radio and telephone 
off to lower antenna. The indicator lamp in the soft 
top switch should go out.

Removal of the key from the steering lock is a safety 
measure ensuring that the key cannot be turned to 
position 2 and the soft top switch is without 
function should anybody push the switch forward 
causing the roof locking mechanism to work. If 
hands are at that moment between roof and car 
body they can be badly injured.6. Lift the hardtop vertically from its attachment points 
(3) and locating points (4) and carefully remove to 
the rear. Exercise caution when maneuvering the 
top. To avoid paint damage, the top’s mounting pins 
must not be allowed to contact the body.
Wa r n i n g !
To prevent possible accidents, drive the vehicle 
only with the hardtop either completely closed and 
locked, or fully lowered into its storage 
compartment.

Control and operation of radio transmitters
Radio and telephone 
1 Observe all legal requirements.
Telephones and two-way radio
Radio transmitters, such as a portable telephone or a 
citizens band unit should only be used inside the 
vehicle if they are connected to an antenna that is 
installed on the outside of the vehicle.
Refer to the radio transmitter operation instructions 
regarding use of an external antenna.
Wa r n i n g !
Please do not forget that your primary 
responsibility is to drive the vehicle. Only operate 
the radio or telephone
1 if road and traffic 
conditions permit.
Bear in mind that at a speed of just 30 mph 
(approximately 50 km/h), your vehicle is covering 
a distance of approximately 50 feet (approximately 
14 m )  e v e r y  s e c o n d .
Wa r n i n g !

built-in or attached antenna (i.e. without being 
connected to an external antenna) from inside the 
vehicle while the engine is running. Doing so could 
lead to a malfunction of the vehicle’s electronic 
system, possibly resulting in an accident and 
personal injury.
