Notice
Adjusting opening height should be programmed at ground level.
A chime sound indicates the new
setting and the outer rear lights will
flash if the tailgate is below an
opening angel of 30°.
When turning the adjuster wheel in
the driver's door to intermediate mode 3/4 , the power tailgate will stop
opening at the newly set position.
The tailgate can only be held open ifa minimum height is exceeded
(minimum opening angle from 30°).
The opening height cannot be
programmed below that height.
Safety function
If the power tailgate encounters an obstacle during opening or closing,
the direction of movement will
automatically be reversed slightly.
Multiple obstacles in one power cycle
will deactivate the function. In this
case, close or open the tailgate
manually.The power tailgate has pinch sensors
on the side edges. If the sensors
detect obstacles between tailgate and chassis, the tailgate will open, until it
is activated again or closed manually.
The safety function is indicated by a
warning chime.
Remove all obstacles before
resuming normal power operation.
If the vehicle is equipped with factory-
fitted towing equipment and a trailer
is electrically connected, the power
tailgate can only be opened with the
touchpad switch or closed with G in
the open tailgate. Ensure that there
are no obstacles in the moving area.
General hints for operatingtailgate9 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, such as a
garage door, to avoid damage to
the tailgate. Always check the
moving area above and behind the
tailgate.
Notice
Power tailgate: If the lifters of the
open tailgate lose pressure, the
tailgate falls a bit and will then be
stopped by the system. Following
the tailgate will be power opened
and closed. During this the tail lights will flash and a chime will sound.
After closing, the tailgate may not be operated until it has been serviced
by a workshop.

Windscreen
Heat-reflecting windscreen The heat-reflecting windscreen has a
coating which reflects solar radiation.
Also data signals, e.g. from toll
stations, might be reflected.
The marked areas on the windscreen are not covered with the coating.
Devices for electronic data recording
and fee payment must be attached in
these areas. Otherwise data
recording malfunctions may occur.
Windscreen stickers
Do not attach stickers such as toll
road stickers or similar on the
windscreen in the area of the interior
mirror. Otherwise the detection zone
of the sensor and the view area of the camera in the mirror housing could be restricted.
Manual windows The rear door windows can be
opened or closed manually with the
window cranks.
Power windows9 Warning
Take care when operating the
power windows. Risk of injury,
particularly to children.
If there are children on the rear seats, switch on the child safety

84StorageLoading information
■ Heavy objects in the loadcompartment should be placedagainst the seat backrests. Make
sure that the backrests are securely engaged, i.e. no longer showing the
red markings on the side near the release lever. If objects can be
stacked, heavier objects should be
placed at the bottom.
■ Secure objects with lashing straps attached to lashing eyes 3 77.
■ Secure loose objects in the load
compartment to prevent from
sliding.
■ When transporting objects in the load compartment, the backrests of
the rear seats must not be angled
forward.
■ Do not allow the load to protrude above the upper edge of the
backrests.
■ Do not place any objects on the load compartment cover or theinstrument panel, and do not cover
the sensor on top of the instrument panel.
■ The load must not obstruct the operation of the pedals, parking
brake and gear selector, or hinder
the freedom of movement of the
driver. Do not place any unsecured objects in the interior.
■ Do not drive with an open load compartment.9 Warning
Always make sure that the load in
the vehicle is securely stowed.
Otherwise objects can be thrown
around inside the vehicle and
cause personal injury or damage
to the load or car.
■ The payload is the difference between the permitted gross
vehicle weight (see identification
plate 3 274) and the EC kerb
weight.
To calculate the payload, enter the
data for your vehicle in the Weights
table at the front of this manual.
The EC kerb weight includes
weights for the driver (68 kg),
luggage (7 kg) and all fluids (tank
90 % full).
Optional equipment and
accessories increase the kerb
weight.
■ Driving with a roof load increases the sensitivity of the vehicle to
cross-winds and has a detrimental
effect on vehicle handling due to
