Towing bracket device
Anti-theft alarm system When the vehicle is locked, the alarm is trig-
ger
ed when the el
ectrical connection be-
tween vehicle and trailer is interrupted.
Always turn off the anti-theft alarm system
before connecting or disconnecting a trailer
››› page 132.
Conditions for the integration of a trailer in
the anti-theft alarm system.
● The vehicle is factory-equipped with an an-
ti-theft al
arm system and a towing bracket
device.
● The trailer is connected electrically to the
tow
ing vehicle by the trailer connector.
● The electrical system of the vehicle and the
trail
er are prepared for operation.
● The vehicle is locked with the ignition key
and the anti-theft al
arm system is activated.CAUTION
For technical reasons, trailers fitted with rear
LED lights ar
e not integrated in the anti-theft
alarm system. Driving tips
Driving with a trailer always requires extra
c
ar e. W
eight distribution
The weight di
stribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.
Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of snak-
ing. Never try to stop the “snaking” by in-
creasing speed.
Always brake in due course. If the trailer has
an overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 116. Electronic stability control*
The ESC* sys
tem helps to stabilise the trailer
in case of skidding or rocking.

cle.
● Washing the vehicle in low temperatures:
when washin
g the vehicle with a hose, do not
direct water into the lock cylinders or the
gaps around the doors. Risk of freezing. For the sake of the environment
To protect the environment, the vehicle
shoul d be w
ashed only in specially provided
wash bays, to prevent toxic, oil-laden waste
water from entering the sewer system. In
some places, washing vehicles outside wash
bays is prohibited. Note
Do not wash the vehicle in direct sunlight. Washing the vehicle with a high pres-

– Always observe the instructions for the
high-pres
sure cleaner, particularly those
concerning the pressure and the spraying
distance.
– Increase the spraying distance for soft ma-
terial
s and painted bumpers.
– Do not use a high pressure cleaner to re-
move ic
e or snow from windows

● To avoid damage to the vehicle, keep a suf-
ficient di
stance from sensitive materials such
as flexible hoses, plastic, soundproofing ma-
terial, etc. This also applies to bumpers pain-
ted in the colour of the bodywork. The closer
the nozzle is to the surface, the greater the
wear on the material. Factory-fitted adhesive sheets

Advice
Removing snow – Use a small brush to remove snow from the
windo
w
s and mirrors.
Removing ice – Use a de-icer spray.
Use a cl
ean cloth or chamois leather to dry
the windows. The chamois leathers used on
painted surfaces are not suitable to clean
windows because they are soiled with wax
deposits which could smear the windows.
If possible, use a de-icing spray to remove
ice. If you use an ice scraper, push it in one
direction only without swinging it.
Use window cleaner or a silicone remover to
clean rubber, oil, grease and silicone depos-
its off.
Wax deposits can only be removed with a
special cleaner available at your Technical
Service. Wax deposits on the windscreen
could cause the wiper blades to judder. Add-
ing a window cleaner that dissolves wax to
the windscreen washer fluid prevents wiper
blades from juddering, but wax deposits are
not removed. CAUTION
● Never u se w
arm or hot water to remove
snow and ice from windows and mirrors. This
could cause the glass to crack! ●
The heatin g el
ement for the rear window is
located on the inner side of the window. To
prevent damage, do not put stickers over the
heating elements on the inside of the win-
dow. Cleaning windscreen wiper blades
Clean wiper blades improve visibility.
1. Use a soft cloth to remove dust and dirt
from the w ind
screen wiper blades.
2. Use window cleaner to clean the wind- scr
een wiper blades. Use a sponge or a
cloth to remove stubborn dirt.
Care of rubber seals If rubber seals are well looked after, they will
not
fr
eez
e so quickly.
1. Use a soft cloth to remove dust and dirt from the rubber seal
s.
2. Apply a specialist care product to the rub- ber seals.
The rubber s
trips on the doors, windows, etc.
will remain pliable and last longer if they are
treated with a suitable rubber care product
from time to time (for example silicone
spray). Caring for rubber seals will also prevent pre-
matur
e ageing and leaks. The doors will be
easier to open. If rubber seals are well looked
after, they will not freeze so quickly in winter.
Door lock cylinder The door lock cylinders can freeze up in win-
ter
.
T
o de-ice the lock cylinders you should only
use spray with lubricating and anti-corrosive
properties.
Cleaning chrome parts 1. Clean chrome parts with a damp cloth.
2. Polish chrome parts with a soft, dry cloth.
If
thi
s
does not provide satisfying results, use
a specialist chrome cleaning product.
Chrome cleaning products will remove stains
from the surface. CAUTION
To prevent scratching chrome surfaces:
● Never use an abrasive cleaning product on
chr ome.
● Do not
clean or polish chrome parts in a
sandy or du
sty environment.260
Advice
●
Never c o
ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes. –
Never ac c
elerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
syst
em or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. WARNING
If the bonnet is not correctly closed, it could
sud den
ly open while driving leaving the driv-
er without visibility. This could result in a se-
rious accident.
● After closing the bonnet, always check that
it is
properly secured by the locking mecha-
nism in the lock carrier piece. The bonnet
must be flush with the surrounding body pan-
els.
● While driving, if you notice that the bonnet
is not
correctly closed then stop immediately
and close it correctly.
● Only open and close the bonnet when there
is no
body within its range. CAUTION
When topping up service fluids, make sure
not t o mi
stake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment . F
or this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet
