and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Note:
When in operation, the seat heater consumes a large 
amount of electrical power. It is not advisable to use the 
seat heater longer than necessary.
The seat heaters may automatically switch off if too 
many power consumers 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 mode). 
The seat heaters will switch on again automatically as 
soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to 
you, the seat heaters can be switched off.

1Left mirror
2Right mirror
To adjust, toggle the switch forward, backward or to 
either side.With the key in steering lock position 2, the driver’s 
side mirror reflection brightness responds to changes in 
light sensitivity.
With gear selector lever in position “R”, or with the 
interior lamp switched on, the driver’s side mirror 
brightness does not respond to changes in light 
sensitivity.
Notes:
The exterior mirrors have electrically heated glass. The 
heater switches on automatically, depending on outside 
temperature.
If the mirror housing is forcibly pivoted from its normal 
position, it must be repositioned by applying firm 
pressure until it snaps into place.

Wa r n i n g !
Exercise care when using the passenger-side 
mirror. The passenger-side exterior mirror is 
convex (outwardly curved surface for a wider field 
of view). Objects in mirror are closer than they 
appear. Check your inside rear view mirror or 
glance over your shoulder before changing lanes.
