4 Tyre pressure loss warning system
G
Risk of accident
The tyre pressure loss warning system*
does not warn you of an incorrectly set tyre
pressure. The table on the inside of the fue l
filler flap will help you decide whether the
tyre pressures should be corrected.
The tyre pressure loss warning system*
does not replace the need to regularly
check your vehicle's tyre pressures, since
an even loss of pressure on several tyres at
the same time cannot be detected by the
tyre pressure loss warning system*.
The tyre pressure loss warning system* is
not able to warn you of a sudden loss of
pressure, e.g. following penetration by a
foreign object.
In the event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so.
While the vehicle is in motion, the tyre pres-
sure loss warning system* monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the spee d
of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning
message will appear in the multi-function dis-
play.
The function of the tyre pressure loss warning
system* is limited or delayed if:
R
snow chains are fitted to your vehicle's
tyres
R road conditions are wintry
R you are driving on sand or grave l
R you adopt a very sporty driving style (cor -
nering at high speeds or driving with high
rates of acceleration)
R you are towing a very heavy or large trailer
R you are driving with a heavy load (in th e
vehicle or on the roof)
Restarting the tyre pressure loss warn-
ing system* Restart the tyre pressure loss warning sys-
tem* if you have
:
R changed the tyre pressure
R changed the wheels or tyre s
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler fla pto ensure that the tyre pressure in all fou
r
tyres is set correctly for the operating con-
ditions concerned .
X Also observe the notes in the section on
tyre pressures (Y page 213). G
Risk of accident
The tyre pressure loss warning system* can
only give reliable warnings if you have set
the correct tyre pressure.
If an incorrect tyre pressure is set, thes e
incorrect values will be monitored.
A tyre with insufficient pressure results in
an instability of the vehicle when driving,
thus increasing the risk of an accident .

G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions, for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a tightening torque of
130 Nm.
For safety reasons, Mercedes-Benz recom -
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wheels may be interchanged every 5,000
km to 10,000 km depending on the degree of
tyre wear, provided that the vehicle has the
same size front and rear tyres. Do not reverse
the direction of tyre rotation. Operation

5 Trailer power suppl
y
When delivered from the factory, your vehi-
cle's trailer socket outlet is equipped with a
permanent power supply and a power supply
that is switched on via the ignition lock .
The permanent power supply is supplied via
trailer socket pin 9.
The power supply that is switched on via the
ignition lock is supplied via trailer socket pin
10.
! You can connect consumers with a power
rating of up to 240 W to the permanen t
power supply and up to 180 W to the power
supply that is switched on via the ignition
lock .
You must not charge a trailer battery using
the power supply.
You can obtain further information about
installing the trailer electrics from a qualified
specialist workshop, e.g. a Mercedes-Ben z
Service Centre.
X To switch the switched power supply on
or off: turn the key in the ignition lock to
position 2or 0, respectively. Trailer with 7-pin connector
If your trailer has a 7-pin connector, you can
connect it to the 13-pin socket on the ball
coupling using an adapter or, if necessary, an
adapter cable. Both of these can be obtained
at a qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre.
Fitting the adapter 1
Connector with lug
2 Socket with groove
X Open the socket cover.
X Insert the connector with lug 1into
groove 2on the socket and turn the con-
nector clockwise to the stop.
X Make the cover engage. X
If you are using an adapter cable, secure
the cable to the trailer with cable ties.
! Make sure that there is sufficient cable
play so that the cable cannot become
detached when cornering. Operation

High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle or - especially - the tyres. Yo u
could otherwise damage the tyres and
cause an accident.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle .
Do not aim directly at any of the following:
R Tyres
R Door joint
R Electrical components
R Batter y
R Connectors
R Bulbs
R Seals
Damaged seals or electrical components
can lead to failures or leaks .Cleaning the wiper blades and the out
-
side of the windscreen G
Risk of injury
Turn the key to position 0in the ignition
lock before cleaning the windscreen or the
wiper blades. There is otherwise a risk of
the windscreen wipers being set in motion
and causing injury.
! Only fold the windscreen wipers away
from the windscreen when vertical, other-
wise you will damage the bonnet.
X Fold the wiper arms away from the wind-
screen until you feel them engage.
X Clean the windscreen and the wiper blades .
X Fold the windscreen wipers back agai n
before the ignition is switched on.
! Do not clean the wiper blades too often,
as otherwise the coating may come off.
This could cause wiper noise.
Cleaning the windows !
Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Clean the insides of the windows with
a
damp cloth or commercially-available glass
cleaner. Avoid touching the inside of the
rear windscreen and the side windows with
hard objects, e.g. ice scrapers or rings. You
could otherwise cause damage to the win-
dows, rear window heating or aerial on the
rear window.
i Anti-glare film retrofitted to the insides of
the windows could interfere with radio or
mobile phone reception, especially if it is
conductive or metal-coated film. Informa -
tion about anti-glare film can be obtained
from any Mercedes-Benz Service Centre.
Cleaning the headlamps X
Clean the headlamp lenses with a wet
sponge.
! Only use washer fluid which is suitable
for plastic lenses. Unsuitable washer fluid
could damage the plastic lenses of th e
headlamps.
Therefore, do not use the following:
R Dry cloths
R Abrasive cleaning agents Operatio
