General hints for operating
tailgate9 Danger
Do not drive with the tailgate open
or ajar, e.g. when transporting
bulky objects, since toxic exhaust
gases, which cannot be seen or
smelled, could enter the vehicle.
This can cause unconsciousness
and even death.
Caution
Before opening the tailgate, check overhead obstructions, e.g. a
garage door, to avoid damage to
the tailgate. Always check the
moving area above and behind the
tailgate.
Notice
The installation of certain heavy
accessories onto the tailgate may
affect its ability to remain open.
Notice
The operation of the power tailgate
is disabled under low vehicle battery
conditions. In this case, the tailgate
may not even by manually operable.
Notice
With the power tailgate disabled and all doors unlocked, the tailgate can
only be operated manually. In this
event, manually closing the tailgate
requires significantly greater force.
Notice
At low outside temperatures the
tailgate may not open fully by itself.
In this case lift the tailgate manually
to its normal end position.

disconnected (e.g. for maintenance
work), the alarm siren must be
deactivated as follows: switch the
ignition on then off, then disconnect
the vehicle's battery within
15 seconds.
Immobiliser
The system is part of the ignition
switch and checks whether the
vehicle is allowed to be started with
the key being used.
The immobiliser is activated
automatically after the key has been removed from the ignition switch.
Notice
Radio Frequency Identification
(RFID) tags may cause interference
with the key. Do not have it placed
near the key when starting the
vehicle.
Notice
The immobiliser does not lock the doors. You should always lock the
vehicle after leaving it and switch on the anti-theft alarm system 3 24,
3 35.
52Seats, restraintsSeat belts
The seat belts are locked during
heavy acceleration or deceleration of
the vehicle, holding the occupants in
the seat position. Therefore the risk of injury is considerably reduced.
9 Warning
Fasten seat belt before each trip.
In the event of an accident, people
not wearing seat belts endanger their fellow occupants and
themselves.
Seat belts are designed to be used by only one person at a time. Child
restraint system 3 61.
Periodically check all parts of the belt
system for damage, soiling and
proper functionality.
Have damaged components
replaced. After an accident, have the
belts and triggered belt pretensioners replaced by a workshop.
Notice
Make sure that the belts are not
damaged by shoes or sharp-edged
objects or are trapped. Prevent dirt
from getting into the belt retractors.
Seat belt reminder
Each seat is equipped with a seat belt
reminder, indicated by a control
indicator X for the respective seat in
the roof console. 3 93.
Belt force limiters
Stress on the body is reduced by the
gradual release of the belt during a
collision.Belt pretensioners
In the event of a head-on, rear-end or
side-on collision of a certain severity,
the front and rear seat belts are
tightened. The front seat belts are
tightened by two pretensioners per
seat. The outer rear seat belts are
tightened by one pretensioner per
seat.9 Warning
Incorrect handling (e.g. removal or
fitting of belts) can trigger the belt
pretensioners.
Deployment of the belt pretensioners
is indicated by continuous illumination
of control indicator v 3 93.
Triggered belt pretensioners must be replaced by a workshop. Belt
pretensioners can only be triggered
once.
Notice
Do not affix or install accessories or
other objects that may interfere with
the operation of the belt
pretensioners. Do not make any
Seats, restraints63In addition to the ISOFIX mounting
brackets, fasten the Top-tether strap
to the Top-tether anchors.
ISOFIX child restraint systems of
universal category positions are
marked in the table by IUF 3 64.
Selecting the right system The rear seats are the most
convenient location to fasten a child
restraint system.
Children should travel facing
rearwards in the vehicle as long as
possible. This makes sure that the
child's backbone, which is still very
weak, is under less strain in the event
of an accident.
Suitable are child restraint systems
that comply with valid UN ECE
regulations. Check local laws and
regulations for mandatory use of child restraint systems.The following child restraints are
recommended for the following
weight classes:
● Group 0, Group 0+ :
Maxi Cosi Cabriofix with or without ISOFIX base for children
up to 13 kg
● Group I : Duo Plus with ISOFIX
and Top-tether for children from 9 kg to 18 kg
● Group II, Group III : Kidfix XP with
or without ISOFIX for children
from 15 kg to 36 kg
● Group III : Graco Booster for
children from 22 kg to 36 kg
Ensure that the child restraint system to be installed is compatible with the
vehicle type.
Ensure that the mounting location of
the child restraint system within the
vehicle is correct, see following
tables.
Allow children to enter and exit the
vehicle only on the side facing away
from the traffic.
When the child restraint system is not
in use, secure the seat with a seat belt or remove it from the vehicle.Notice
Do not affix anything on the child restraint systems and do not cover
them with any other materials.
A child restraint system which has
been subjected to stress in an
accident must be replaced.
