Heated  Seats

The front seat heaters can  be 

switched  on with the  key in  steering 
lock positions  1  or 2, the rear seat 
heaters only  in  steering  lock 
position  2.

The switches for the front seats are 

located at the forward end  of the 

center console,  those for the rear 
seats  are  located  in  the  rear doors.

Heater  operation:

Push  in  upper switch  portion;  position
1  =  normal  heater operation,  one  indi­

cator  lamp  lights  up.

Push  in  lower switch  portion;  position

2  =  rapid  heating,  both  indicator 

lamps  light  up.

After approximately 5  minutes  in the 

rapid  heating  mode, the heater auto­
matically switches to normal  opera­

tion and only one indicator lamp will 
stay  on.

Turning  off  heater:

If one  indicator lamp  is on,  press  in 

upper  part  of switch,  position  1.

If both  indicator lamps are on,  press 

in  lower  part  of switch,  position  2.

The  heater  automatically turns  off 
after approximately 30 minutes of 
operation.

Notes:

When  in operation, the seat heater 
consumes a large amount of power.  It 

is advisable not to use the seat heater 
longer than  necessary.

The seat heaters  may automatically 
switch off if too many power con­
sumers are switched on at the same 
time,  or if the battery charge is low. 
When this occurs, the indicator lamp 

in the switch will  blink (both  indicator 
lamps blink during  rapid  seat heating). 

The seat heaters will switch on again 
as soon as sufficient voltage is avail­
able.

If the blinking of the indicator lamps is 
distracting to you, the seat heaters 

can be switched off.
