Important safety notes
G
WARNING
Children could become trapped if they adjust the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle.
The seats can still be adjusted when there is
no SmartKey in the ignition lock. G
WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. G
WARNING
If you adjust the seat height carelessly, you or other vehicle occupants could be trapped andthereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem. G
WARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat. G
WARNING
If head restraints are not installed and adjus-
ted correctly, they cannot provide protection
as intended. There is an increased risk of
injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
! To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see "Interior care". Seats

0050Solutions The seat heating has
switched off prema-
turely or cannot be
switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Programming Programming buttons
Pay attention to the "Important safety notes"
(Y page 311). Garage door remote control
0083is not inclu-
ded with the integrated garage door opener.

X Select one of buttons 0044to0085 to use to
control the garage door drive.
X To start programming mode: press and
hold one of buttons 0044to0085 on the inte-
grated garage door opener.
The garage door opener is now in program-
ming mode. After a short time, indicator
lamp 0043lights up yellow.
Indicator lamp 0043lights up yellow as soon
as button 0044,0087or0085 is programmed for
the first time. If the selected button has
already been programmed, indicator lamp
0043will only light up yellow after ten
seconds have elapsed.
X Release button 0044,0087or0085. Indicator
lamp 0043flashes yellow.
X To program the remote control: point
garage door remote control 0083towards

(Y page 312).
X Release button 0084on remote control 0083for
the garage door drive system.
If indicator lamp 0043lights up red: repeat the
programing procedure for the correspond-

doing so, vary the distance between remote control 0083and the rear-view mirror.
The required distance between remote
control 0083and the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
(Y page 311).
If the garage door system uses a rolling code,
you will also have to synchronize the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. The program-
ming button may be positioned at different
locations depending on the manufacturer. It
is usually located on the door drive unit on the garage ceiling.
Familiarize yourself with the garage door
