trol without the key in the ignition slot. Seat
adjustment is normally made when the ignition
is on and can always be made when the engine
is running.

can be used at the same time.
•The power seats have an overload pro-
tector that activates if a seat is blocked
by any object. If this occurs, switch off
the ignition (key in position 0) and wait
for a short period before operating the
seat again.

Remote key memory and the power
driver's seat* and door mirrors2
Each remote key has a feature that enables it
to store (remember) the position of the power
driver's seat and door mirrors when the vehicle
is locked with that remote key.
This feature has to be activated for each of the
remote keys used in the vehicle as follows:
1. Insert a remote key in the ignition slot.2.
Go into the MY CAR menu and go to
Settings
Car settingsCar key
memory
3. To activate the remote key memory fea-
ture, press ENTER (check the box).
> The remote key is now ready to store the
position of the power driver's seat and
door mirrors.
Repeat this procedure for each of the vehicle's
remote keys.
See page 191 for a description of the menu
system.
Storing the positions of the power
driver's seat/mirrors in the remote key
1. Move the seat and door mirrors to the
desired position using the seat and mirror
adjustment controls.
2. Exit the vehicle and lock the doors with the
remote key (or close the driver's door and
press the lock button on the door handle
with the remote key in your possession on
vehicles with the optional keyless drive).
> The positions of the power driver's seat
and door mirrors are now stored in the
remote key's memory.
NOTE
The remote key's memory feature and the
power driver's seat memory function (the
settings made using the buttons on the side
of the seat, see the section "Power seat
memory function" on page 87) work inde-
pendently of each other.
Returning the seat/mirrors to the stored
positions
To move the seat and door mirrors to the posi-
tion stored in the remote key:
1.
Unlock the driver's door with the same
remote key (the one used to lock the
doors). For models equipped with the
optional keyless drive, you must have the
same remote key in your possession.
2. Open the driver's door within 2 minutes.
The driver's seat and door mirrors will auto-
matically move to the position in which you left
them (if the vehicle has been unlocked with one
of the other keys and new seat/mirror adjust-
ments have been made).
2This information also applies to vehicles with the optional keyless drive.

ferent position and locked the vehicle
with a different remote key.

folded down for prolonged periods. This
could result in pressure marks in leather
upholstery.
WARNING

allowed to sit in the outboard rear seat posi-
tions if the head restraints are folded down.
If these positions are occupied, the head
restraints should be in the upright (fixed)

Folding down the rear seat backrestsThe three sections of the rear seat backrest can
be folded down in different combinations to
make it easier to transport long objects.
•The left (driver's side) section can be folded
down separately.
•The center section can be folded down
separately.
•The right (passenger's side) section can
only be folded down together with the cen-
ter section.

there should be no objects on the rear seat
and the seat belt should not be buckled
when the backrest is folded down.

restraint (see page 89) if the center and/or
right section of the backrest is to be low-
ered. The outboard head restraints fold
down automatically.
Pull up the backrest release control on the
respective section(s) (

rest is returned to the upright position,
check that it is properly locked in place
by pushing and pulling it. The red indi-
cators should also not be visible.
•Return the outboard head restraints to
the upright position.
•Long loads should always be securely
anchored to help avoid injury in the
event of a sudden stop.
•Always turn the engine off and apply the
parking brake when loading/unloading
the vehicle.
•Place the transmission in the Park (P)
position to help prevent inadvertent
movement of the gear selector.
•On hot days, the temperature in the
vehicle interior can rise very quickly.
Exposure of people to these high tem-
peratures for even a short period of time
can cause heat-related injury or death.
Small children are particularly at risk.
