You must reset the electric sliding door if there
has been a malfunction or an interruption in the
voltage supply (
Ypage 78).
iPlease note, if the child-proof locks have
been activated, you cannot open the sliding
door from the inside. You can only open a
sliding door from the inside if the child-proof
locks have not been activated. Further infor-
mation can be found under "Child-proof locks
for the sliding door" (
Ypage 63) and "Open-
ing/closing from the inside" (Ypage 77).
Obstacle detection with reversing
feature
The sliding door is equipped with automatic
obstacle detection with reversing feature. If a
solid object blocks or restricts the sliding door
during the automatic closing process, the slid-
ing door opens again automatically. If the sliding
door is obstructed during the opening proce-
dure, it moves back a few centimeters in the
opposite direction and stops.
Automatic obstacle detection with reversing
feature is only an aid. It is not a substitute for
your attentiveness when closing the electrical
sliding door.
If an obstacle is detected, the display shows the
Left-hand Electric Sliding Door
ObstructionDetectedmessage for example,
and five warning tones sound.
GWARNING

Tailgate
Important safety notes
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate
is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open.
!The tailgate swings upwards and to the rear
when opened. Therefore, make sure that
there is sufficient clearance above and behind
the tailgate.

Also observe the notes under "Winter operation"
(
Ypage 279).
Driving off-road
Important safety notes
GWARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
GWARNING
When driving off-road, your body is subject to
forces from all directions, due to the uneven
surface. You could be thrown from your seat,
for instance. There is a risk of injury.
Always wear a seat belt, even when driving off-
road.
GWARNING
If you drive over obstacles or in ruts, the steer-
ing wheel may jerk out of your grip, causing
injury to your hands.
Always hold the steering wheel firmly with
both hands. When driving over obstacles, you
must expect steering forces to increase
briefly and suddenly.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
!When driving off-road or on unpaved surfa-
ces, check the underside of the vehicle and
the wheels and tires at regular intervals. In
particular, remove any trapped foreign
objects, e.g. stones and branches.
Such foreign objects may:
Rdamage the chassis, the fuel tank or the
brake system
Rcause imbalances and thus vibrations
Rbe flung out when you continue driving
If there is any damage, inform a qualified spe-
cialist workshop.
When driving off-road and on construction sites,
sand, mud and water mixed with oil, for exam-
ple, may get into the brakes. This may lead to a
reduction in braking performance or total brake
failure, also as a result of increased wear. The
braking characteristics will vary depending on
the material that has got into the system. Clean
the brakes after driving off-road. If you then
notice reduced braking performance or hear
scraping noises, have the brake system checked
at a qualified specialist workshop. Adjust your
driving style to the changed braking character-
istics.
Driving off-road or on construction sites increa-
ses the possibility of vehicle damage which may
in turn lead to the failure of certain assemblies
and systems. Adapt your driving style to the off- road driving conditions. Drive carefully. Have
any vehicle damage rectified at a qualified spe-
cialist workshop as soon as possible.
When loading your vehicle for driving off-road or
on a construction site, keep the vehicle's centerof gravity as low as possible.
Rules for driving off-road
!Always bear the vehicle's ground clearance
in mind and avoid obstacles, e.g. deep ruts.
Obstacles may damage the following parts of the vehicle:
Rthe chassis
Rthe drive train
Rthe fuel and supply tanks
For this reason, you should always drive
slowly when driving off-road. If you have to

In the event of an accident, have a damaged
cargo compartment floor or loading area, the
cargo tie-down rings and the tie down checked
at a specialist workshop. Otherwise, the load
may not be correctly secured the next time any-
thing is stowed.
Even if you follow all loading guidelines, the load
increases the risk of injury in the event of an
accident. Observe the information in the "Secur-ing a load" (
Ypage 244) and "Load distribution"
(Ypage 243) sections.
You will find information about the maximum
roof load under "Cargo tie-down points and car-
rier systems" (
Ypage 312). You will find infor-
mation about roof carriers under "Carrier sys-
tems" (
Ypage 248).
Before loading
!
The anti-slip mats cannot be used for secur-
ing goods and must be replaced when they
show signs of:
RPermanent deformation and crushing
RCrack formation
RCuts
XTire pressure: check the tire pressure and
correct if necessary (Ypage 280).
XCargo compartment floor: clean the cargo
compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to pre-
vent the load from slipping.
XPlace non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary.
During loading
XObserve the gross axle weight rating and per-
missible gross vehicle weight for your vehicle.
Take into account that your vehicle's curb
weight is increased if accessories or optional equipment are installed. The maximum pay-
load is thus reduced.
XObserve the notes on load distribution
(Ypage 243).
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.
XSecure the load (Ypage 244).
Observe the legal requirements of the country
in which you are currently driving.
Checks after loading
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tail-
gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is a risk of poisoning.
Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open.
XSecuring luggage/loads: make sure that
the luggage and/or load is secure before
every journey and at regular intervals during a
long journey, and correct it if necessary.
XDoors/tailgate: close the sliding doors and
tailgate/door.
XTire pressure: adjust the tire pressure
according to the vehicle load (Ypage 280).
XDriving style: adapt your driving style
according to the vehicle load.
Load distribution
General notes
!
Excessive loads on individual points of the
cargo floor or on the load surface impair vehi-
cle handling characteristics and could cause
damage to the floor covering.
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.

ervoir has fallen to the MIN mark or below,
check the brake system immediately for
leaks. Also check the thickness of the brake
linings. Visit a qualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
the malfunction.
!Brake fluid corrodes paint, plastic and rub-
ber. Ifpaint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake fluid renewed every two years at a qualified specialist workshop. Observe the
