To operate the front power seat adjustment switches, 
turn the electronic key in starter switch to position 1 
or 2 (with a front door open, the power seats can also be 
operated with the electronic key removed or in starter 
switch position 0).
Wa r n i n g !
Do not adjust the driver’s seat while driving. 
Adjusting the seat while driving could cause the 
driver to lose control of the vehicle.Never ride in a moving vehicle with the seat back 
reclined. Sitting in an excessively reclined position 
can be dangerous. You could slide under the seat 
belt in a collision. If you slide under it, the belt 
would apply force at the abdomen or neck. That 
could cause serious or fatal injuries. The seat back 
and seat belts provide the best restraint when the 
wearer is in an upright position and belts are 
properly positioned on the body.Never place hands under seat or near any moving 
parts while a seat is being adjusted.
When leaving the vehicle always remove the 
electronic key from the starter switch, take the 
KEYLESS-GO-card (if so equipped) with you, and 
lock your vehicle. The power seats can also be operated with the 
driver’s or front passenger door open. Do not leave 
children unattended in the vehicle, or with access 
to an unlocked vehicle. Unsupervised use of vehicle 
equipment may cause serious personal injury.

The switches are located in each front door.
We recommend to adjust the power seat in the following 
order:
1Seat adjustment, fore / aft
Press the switch (fore / aft direction) until a 
comfortable seating position is reached that still 
allows you to reach the accelerator / brake pedal 
safely. The position should be as far rearward as 
possible, consistent with ability to properly operate 
controls.Note:
Do not move the front passenger seat completely 
forward if objects are stored in the parcel net in the 
front passenger-side footwell. Items in the net may 
be damaged. 
2Press and hold the E button.
When depressed, the exterior mirrors, interior 
mirror and steering wheel position are preset based 
on the fore / aft position of the driver’s seat. 
Only minor personal adjustments, as described 
below, should then be required.
For steering wheel adjustment, see page 105;
rear view mirror, see page 106;
exterior rear view mirrors, see page 107.
3Seat, up / down
Press the switch (up / down direction) until 
comfortable seating position with still sufficient 
headroom is reached.

The multicontour backrest is equipped with a 
massage function to help prevent fatigue during 
longer journeys.
The PULSE function inflates and deflates the air 
cushions in the backrest rhythmically.
An indicator lamp on the switch lights up when the 
PULSE function is switched on. The PULSE function 
switches off automatically after approximately 
5minutes.
Note:
If the top cushion is inflated, only the middle air 
cushion is inflated and deflated.Seat heater
The seat heaters can be switched on with the electronic 
key in starter switch positions 1 or 2. 
The buttons are located on each door.
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. In this case, one or 
both indicator lamps will blink. 
The seat heaters switch back 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.

Seat ventilation system
The buttons are located on each door.
Seat ventilation can be activated manually with the 
electronic key in starter switch positions 1 or 2, or by 
the summer opening function, see page 45.
Notes:
When in operation, the seat ventilation system 
consumes a large amount of electrical power. It is not 
advisable to use the seat ventilator longer than 
necessary.The seat ventilators may automatically switch off if too 
many power consumers are switched on at the same 
time or if the battery charge is low. In this case, one or 
more indicator lamps will blink.
The seat ventilation switch back on again automatically 
as soon as sufficient voltage is available.
If the blinking of the indicator lamps is distracting to 
you, the seat ventilators can be switched off.
The maximum ventilation level (level 3) is automatically 
selected if the driver’s seat ventilation is activated by 
the summer opening function, see page 45.
