vated.
i PARKTRONIC is automaticallya ctivated
when you turn the key to position 2in the
ignition lock.
Trailer towing* PARKTRONIC is deactivated for the rear area
when you establish an electrical connection
between your vehicle and atrailer.
! Fold in the ball coupling if the trailer tow
hitch is not required.P ARKTRONIC meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling. Parking Guidance*
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle. A
suitablep arking space is indicated by the
parking symbol. You receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 138). G
Risk of accident
Parking Guidance is merely an aid and may
recommend parking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited, drive-
ways, unsuitables urfaces, etc.
Parking Guidance measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Parking Guidance does not relieve you of the
responsibility for paying attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourselfa nd others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
Risk of accident
Objects located above the height range of
Parking Guidance will not be detected when
the parking space is measured. These are not
taken into account when the parking proce-
dure is calculated, e.g. overhanging loads, tail
sections or loading ramps of goods vehicles.
In some circumstances, Parking Guidance
might therefore issue steering instructions
too soon. This may lead to acollision. For this
reason, you should avoid using Parking Guid-
ance in such situations. 140

X Check that the bonnet has engage dprop-

i If the bonnet can be raiseds lightly, it is
not properl yengaged. Open it again and
close it with alittle more force. Engine oil
Depending on driving style, the vehicle con-
sumes up to 0.8 loil per 1,000 km. The oil
consumption may be highert han this when
the vehicle is new or if you frequently drive at
high engine speeds.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle shouldbe
met:
R
the vehicle shouldbep arked on level
ground.
R the engine shouldbes witched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine shouldbes witched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
Depending on the engine, the oil dipstick may
be installed at adifferent location. E3

X Wipe off oil dipstick 0046.
X Insert oil dipstick 0046into the oil dipstick

The oil level is correct if the level is between
the minimum mark 008Aand maximum
mark 0047.
X Top up the oil if necessary.
Topping up the engine oil H
Environmental note
When topping up the oil, take care not to spill
any. Oil must not be allowed to escape into
the soil or waterways. You would otherwis ebe
damaging the environment. Cap (example)
X Turn cap 0046anti-clockwise and remove.
X Top up with the amount of oil required
(Y page 288).
i The difference in quantity betwee nthe
minimum mark and maximu mmark is
approximately 2litres.
i On vehicle switha4-cylinder petrol
engine and vehicle swith an 8-cylinder pet-
rol engine, the difference betwee nthe MIN
mark and the MAX mark is approximately
1.5 litres.

atrailer G
Risk of accident
When reversin gthe vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load R
the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section.
i When towing atrailer, set the tyre pres-
sure on the rear axle of the towing vehicle
for am aximum load; see the tyre pressure
table in the fuel filler flap.
You will find installation dimensions and loads
in the "Technical data" section
(Y page 303).
The maximum drawbar load of the trailer
drawbar on the ball coupling is 75 kg. How-
ever, the actual noseweight must not exceed
the value given on the trailer tow hitch and
trailer identification plates. The lowest weight
applies.
! Use anoseweight as close as possible to
the maximum permissible noseweight. Do
not use anoseweight of less than 50 kg,
otherwise the trailer may come loose.
Bear in mind that the payloa dand the rear
axle load are reduced by the actual nose-
weight.
Please notet hat when towing atrailer, PARK-
TRONIC* (Y page 140) and Parking Guid-
ance* (Y page 143) are only availabl ewith
limitations ,ornot at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use atrailer with aheight-adjustable trailer
drawbar. 194
