WARNING Risk of accident when the low
beam is switched off in poor visibility
When the light switch is set to0058 ,th e low
beam may not be switched on automatically if
th ere is fog, snow or other causes of poor vis‐
ibility such as spr ay. #
In such cases, turn the light switch to
0058 . The automatic low beam is only an aid.
Responsi‐
bility forve hicle lighting rests with you.

ately in theev ent of fog, snow or spr ay. Other‐
wise, the low beam is temp orarily inter rupte d.
Switching the automatic low beam on:
R Turn the light switch tothe0058 position.
Switch thevo ltage supply on: the parking
light automatically switches on or off depend‐
ing on the sur rounding brightness.
The daytime running la mps are switched on
when the engine is running. The pa rking light
and the low beam also switch on or off
depending on the sur rounding brightness.
When the low beam is switched on, the0058

tector &
WARNING Risk of inju ryby laser beam
from motion de tector
The motion de tector transmits invisible radia‐
tion from LEDs (light-emitting diodes).
These LEDs are classified under the 1M laser
class and can cause retina dama geinthefo l‐
lowing situations:
R Ifyo u look directly into the unfiltered
laser beam from the motion de tector for
an extended pe riod
R Ifyo u look direct lyinto the laser beam of
th e motion de tector wi thoptical instru‐
ments such as eyeglasses or a magnifying
gl ass. #
Never look directly into the laser beam. The motion de
tector is loca ted in the cargo com‐
partment behind the partition, in the middle of
th ero of. 1
Position of motion de tector
If th eve hicle is equipped with a motion de tector,
th e cargo compartment lighting is also activated
via the motion de tector.
If th e motion de tector de tects mo vement in the
cargo compa rtment while theve hicle is station‐
ar y, the cargo compartment lighting switches on
fo r appro ximately two minu tes.
The cargo compartment lighting can be switched
on via the motion de tector if:
R The vehicle is stationar y,the parking brake is
applied and the brake pedal is not being
depressed.
R Vehicles with automatic transmission: the
selector le ver is in position 005Dand you are
not depressing the brake pedal.
R The vehicle has not been loc ked from the out‐
side using thekey.
If no change totheve hicle, such as a door open‐
ing, is de tected over se veral hours, the motion
de tector will au tomatically switch off. This pre‐
ve nts the battery from discharging. Switching interior lighting delay time on/off

In particular, do not park on dry grass‐
land or har vested grain fields. If
th eve hicle is predominantly used for short dis‐
ta nce driving or extended non-operational times,
th is could lead toa malfunction in the automatic
cleaning function forth e diesel particulate filter.
As a result, permanent blocking of the diesel par‐
ticulate filter may occur and fuel may also accu‐
mulate in the engine oil and cause engine failure.

The permissible gross
weight forve hicle-trailer
combinations (GCWR) is calculated byadding the
gross weight of the trailer tothe gross vehicle
we ight including a driver's weight of appr ox‐
imately 150 lbs (68 kg). The maximum permissi‐
ble gross combination weight is vehicle-specific
and equipment-dependent. When driving with a
trailer, you should not exceed the maximum per‐
mitted permissible gross weight forve hicle-trailer
combinations (GCWR).
The permissible values, which must not be excee‐
ded, can be found in your vehicle documents and
on the identification plates of the trailer tow
hitch, the trailer and theve hicle. The values
appr ovedby the manufacturer can also be found
in the "Technical data" section. Where theva lues
dif fer, th e lo west value alw ays applies.
Loading the trailer
Use a dr awbar nose weight that is as close as
possible tothe maximum permissible nose‐
we ight. Do not undershoot the minimum permis‐
sible nose weight. Otherwise, the trailer may
become de tach ed.
R Distribute the load over theve hicle and the
trailer so as not toexceed either the maxi‐
mum permissible values forth e gross vehicle
we ight rating (GVWR) and gross trailer weight
(G TW ),th e permissible gross weight forve hi‐
cle-trailer combinations (GCWR), nor the max‐
imum permissible gross axle weight rating
(GAWR) and trailer dr awbar nose weight (TWR)
of your vehicle.
R Addth ere ar axle load tothe trailer dr awbar

head (TWR). This will ensure that you do not
ex ceed the permissible gross axle weight rat‐
ing (G AWR).
R Addth eve hicle load tothe trailer dr awbar
nose weight of the trailer dr awbar on the ball

R Make sure that thewe ights of theto wing
ve hicle and the trailer comply with the maxi‐
mum permissible values. Ha vethe car/t railer
combination weighed on a calibrated weigh‐
ing machine. The car/trailer combination
comprises theto wing vehicle including driver,

Check the maximum permissible gross axle
