Seat heater
The seat heaters can be switched on with the electronic
key in steering lock positions 1 or 2.Notes:
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.

Note:
The exterior mirrors have electrically heated glass. The
heater switches on automatically, depending on outside
temperature.
If an exterior mirror housing is forcibly pivoted from its
normal position, it must be repositioned by applying
firm pressure until it snaps into place.
The automatic antiglare function will not react for
example, if the rear window sun shade is in raised
position.Important!
Electrolyte drops coming into contact with the vehicle
paint finish can only be completely removed while in
their liquid state, by applying plenty of water.
Storing mirror positions in memory
The exterior rear view mirror positions are stored in
memory with the seat / head restraint / steering column
positions and can be recalled when necessary, see
page 45.
