When the anti-dazzle function is enabled, the
interior rear vision mirror will darken auto-
matically according to the amount of light it
receives. The anti-dazzle function is cancel-
led if reverse gear is engaged. Note
● The autom atic
anti-dazzle function will only
work properly if the sun blind* for the rear window is retracted and there are no other
ob
j
ects preventing light from reaching the in-
terior rear vision mirror.
● If you have to stick any type of sticker on
the winds
creen, do not do so in front of the
sensors. Doing so could prevent the anti-daz-
zle function from working well or even from
working at all. Folding in the exterior mirrors man-

WARNING
● Con v
ex or aspheric mirrors increase the
field of vision however the objects appear
smaller and further away in the mirrors. If you
use these mirrors to estimate the distance to
vehicles behind you when changing lane, you
could make a mistake. Risk of accident. ●
If po s
sible, use the rear vision mirror to es-
timate distances to vehicles behind you.
● Make sure that you do not get your finger
trapped betw
een the mirror and the mirror
base when folding back the mirrors. Risk of
injury! For the sake of the environment
The exterior mirror heating should be switch-
ed off when it i
s no longer needed. Other-
wise, it is an unnecessary fuel waste. Note
● If the el ectric
al adjustment ever fails to op-
erate, the mirrors can be adjusted by hand by
lightly pressing the edge of the mirror glass.
● In vehicles with electric exterior mirrors,
the fol
lowing points should be observed: if,
due to an external force (e.g. being knocked
while manoeuvring), the adjustment of the
mirror housing is altered, the mirror will have
to be fully folded electrically. Do not readjust
the rear vision mirror housing by hand, as
this will interfere with the mirror adjuster
function.
● The rear vision mirrors can be adjusted sep-
arately
or simultaneously, as described
above.
● The fold-in function on the exterior mirrors

Towing bracket device and trailer
Towing bracket device and
tr ai
l
er
Driving with a trailer What do you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c
orrect equipment.
If the car is supplied with a factory-fitted tow-
ing bracket it will already have the necessary
technical modifications and meet the statuto-
ry requirements for towing a trailer. If you
wish to retrofit a towing bracket, consult
››› page 188.
Connectors
Your vehicle is fitted with a 12-pin connector
for the electrical connection between the
trailer and the vehicle.
If the trailer has a 7-pin plug you will need to
use an adapter cable. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum permitted trailer weight, you can then
climb correspondingly steeper slopes. The maximum trailer weights listed are only
app
lic
able for altitudes up to 1000 m above
sea level. With increasing altitude the engine
power and therefore the vehicle climbing
ability are impaired because of the reduced
air density. The maximum trailer weight has
to be reduced accordingly. The weight of the
vehicle and trailer combination must be re-
duced by 10% for every further 1000 m (or
part thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the towing bracket, but do not exceed the
specified limit.
The figures for trailer weights and drawbar
loads that are given on the data plate of the
towing bracket are for certification purposes
only. The correct figures for your specific
model, which may be lower than these fig-
ures for the towing bracket, are given in the
vehicle documentation or in ››› chapter Tech-
nical Data .
Distributing the load
Distribute loads in the trailer so that heavy
objects are as near to the axle as possible.
Loads carried in the trailer must be secured
to prevent them moving. Tyre pressure
Set tyr
e pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear. WARNING
Never transport people in a trailer. This could
re s
ult in fatal accidents. Note
● To w
ing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to to
wing a trailer in your country. 187

Sensors and camera lenses ●
Use a small brush to remove snow and a
de-icer s pr
ay to remove ice.
● Clean the sensors with a solvent-free prod-
uct and a soft, dr
y cloth.
● Moisten the camera lens using a standard
alcohol-b
ased glass cleaning agent and
clean the lens with a dry cloth. CAUTION
● When y ou c
lean the vehicle with a pressure
washer:
–Stay a suitable distance from the sensors
on the front and rear bumpers.
– Do not clean the camera lenses or sur-
rounding area with the pressure washer.
● Never use warm or hot water to remove
snow and ic
e from the reverse camera lens,
as it could crack the lens.
● Never use abrasive cleaning agents on the
lens. Vehicle paint maintenance
Regular waxing protects the paintwork.
Y
ou need t
o ap
ply wax to your vehicle if water
does not form small drops and run off the
paintwork when it is clean.
Good quality hard wax products are available
at your Technical Service. Regular wax applications help to protect the
paintwork
from environmental contaminants
››› page 191. It is also effective in protecting
against minor scratches.
Even if a wax solution is used regularly in the
vehicle washing tunnel, it is advisable to pro-
tect the paint with a hard wax coating at least
twice a year.
Polishing the paintwork Polishing is only necessary if the paint has
lo
s
t
its shine, and the gloss cannot be
brought back by applying wax. Polishing
products can be purchased in your Technical
Service.
The vehicle must be waxed after polishing if
the polish used does not contain wax com-
pounds to seal the paint ››› page 194, Vehicle
paint maintenance . CAUTION
To prevent damage to the paintwork:
● Do not use polishes and hard wax on pain-
ted p ar
ts with a matt finish or on plastic
parts.
● Do not polish your vehicle in a sandy or
dusty
environment. Caring for plastic parts
If normal washing fails to clean plastic parts,
cl
e
an them with approved solvent-free plas-
tic cleaning and care products. CAUTION
● The use of li
quid air freshener directly over
the air vents of the vehicle may damage the
plastic parts if the liquid is accidentally spil-
led.
● Cleaning products which contain solvents
wil
l damage the material. Cleaning of windows and mirrors
Cleaning windows
– Moisten the windows with commercially
av ai
l
able, alcohol based glass cleaner.
– Dry the windows with a clean chamois
leather or a lint
-free cloth.
Removing snow – Use a small brush to remove snow from the
window
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
194
Care and maintenance
painted surfaces are not suitable to clean
w indo
w
s 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 heating element for the rear window is
located on the inner s
ide 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 se al
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-
mature 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-
t
er
. T
o de-ice the lock cylinders you should only
use spr
ay 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. Steel wheel rims
–
Clean steel wheel rims regularly using a
sep ar
at
e sponge.
Use an industrial cleaner to remove brake
dust. Any damage to the paint on steel wheel
rims should be repaired before starting to
rust. »
