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 .
Configuring with the multi-function steer-
ing wheel

the ignition lock .

Downhill gradient
sOn long and steep downhill stretches, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or,
on vehicles with automatic transmission*,
select shift range 1,2 or 3.
i This also applies if you have activated
cruise control* or Speedtronic*.
This uses the braking effect of the engine and
you will not have to brake to such an exten t
to maintain the same speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need additional braking ,
depress the brake pedal repeatedly rather
than continuously.
Heavy and light loads If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly. G
Risk of accident
Never depress the brake pedal continu -
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If you drive for a long time in the rain without
braking, there may be a delayed reaction
when you first brake and you will have to
depress the pedal harder.
You must therefore maintain a greater dis-
tance from the vehicle in front.
Brake firmly after driving on a wet road. Thi
s
way the brake discs will become warm, dryin g
more quickly, which will protect them against
corrosion. Limited braking performance on salted
roads G
Risk of accident
The layer of salt on the brake discs and the
brake linings may cause a delay in the brak-
ing effect, resulting in a significantly longer
braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully when you
are driving on salted roads, so that any
layer of salt that may have started to
build up on the brake discs and the brake
linings is removed without putting other
road users at risk.
R maintain a greater distance to the vehicl e
ahead and drive with particular car e
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues ar e
removed from the brake disc.
New brake linings For safety reasons, Mercedes-Benz recom
-
mends that you have only brake pads/linings
fitted to your vehicle that have been approved Operation

An extensive Mercedes-Benz Service networ k
is also available in other countries. You can
obtain the relevant workshop directories
from any Mercedes-Benz Service Centre.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 204). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. Oncoming traf -
fic will be dazzled less .
X Have the headlamps switched over at a
qualified specialist workshop, e. g. a
Mercedes-Benz Service Centre. G
Risk of accident
Have your headlamps switched back to
asymmetrical dipped beam if you visit a
country in which traffic drives on the same
side of the road as in the country in which
your vehicle was registered. You may oth- erwise dazzle the oncoming traffic and
could cause an accident.
Trailer towing*
Folding out the ball coupling
Please also observe the notes on the restric-
ted function of Parktronic* when towing a
trailer on (Y page 155).
Before you can tow a trailer with your vehicle,
you must fold out the ball coupling.
The release wheel is located behind the left-
hand side trim panel in the boot/luggage
compartment . G
Risk of accident
Make sure that the ball coupling is
engaged, either in its folded out or folded
in position, and that the indicator lamp is
off.
Do not turn the release wheel when a traile r
is coupled up. The trailer might otherwise
become detached. Operation

specification, it is greased or dry (without
grease) when used. Notes on towing a trailer
G
Risk of accident
When reversing the 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 permitted trailer drawbar nose-
weight
R The permitted trailer load
R The permitted 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
vehicle documents. You will find the values approved by the
manufacturer on the vehicle identification
plates and those for the towing vehicle in
the “Technical data” section.
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg.
However, the weight must not exceed the fig-
ure given on the trailer hitch and trailer iden-
tification plates. The lowest weight applies.
! Use a noseweight as close as possible to
the maximum permissible noseweight. Do
not use a noseweight of less than 50 kg,
otherwise the trailer may come loose.
Bear in mind that the payload and the rear
axle load are reduced by the actual nose-
weight.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable draw-
bar.
Coupling up a trailer G
Risk of injury
Do not connect a trailer with an engaged
overrun brake. Otherwise, your hand could become trapped between the bumper and
drawbar.
! Do not uncouple a trailer with overru n
brake between the bumper and drawbar,
otherwise your vehicle could be damaged
by the spring action of the overrun brake.
X Position the trailer level behind the vehicle.
X Couple up the trailer .
X Establish the electrical connectio n
between the vehicle and the trailer.
Driving tip s In Germany, the maximum permitted speed
for vehicle/trailer combinations is 80 km/h.
!
A maximum speed of 80 km/h should not
be exceeded, even in countries where
higher speeds are permitted for vehicle /
trailer combinations.
When towing a trailer, your vehicle's handling
characteristics will be different in compariso n
to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capabilit yOperation
