WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified newfuses of the correct amperage.
! Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Only use fuses marked with an "S". Compo-
nents or systems could otherwise be dam-
aged.
! Make sure that no moisture can enter the
fuse box when the cover is open.
! When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper- ation of the fuses.
The fuses in your vehicle disconnect faulty cir-
cuits. If a fuse blows, all the components in the circuit and their functions will fail.
Blown fuses must be replaced with fuses of the same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart.
The fuse allocation chart is in the fuse box in the front-passenger footwell (Y page 332).
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified special- Fuses

Only screw standard valve caps or valve caps
specifically provided by Mercedes-Benz for
your vehicle onto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident.
R Check the tyre for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days.
The recommended tyre pressures for various
operating conditions can be found on the tyre
pressure table on the fuel filler flap
(Y page 164).
Operation with an emergency spare wheel:
information on operation with an emergency
spare wheel can be found in the general notes in the "Emergency spare wheel" section
(Y page 348).
Operation with a trailer: the applicable value
for the rear axle is the maximum value stated in the tyre pressure table inside the fuel filler flap.
Additionally, the tyre pressure table may also
state tyre pressures for different load condi-
tions. These are defined in the table as different numbers of passengers and amounts of lug-
gage. The actual number of seats may vary; for
more information, please refer to the vehicle
documents.
If tyre sizes are not specified, the tyre pressures
stated on the tyre pressure table apply for all
tyres approved at the factory for this vehicle. If a tyre size precedes a tyre pressure, the fol-
lowing tyre pressure information is valid only for that tyre size.
Use a suitable pressure gauge to check the tyre
pressure. The outer appearance of a tyre does
not give any reliable indication of the tyre pres-
sure. On vehicles fitted with the electronic tyre
pressure monitor, you can also check the tyre
pressure using the on-board computer.
If possible, correct tyre pressures only when the
tyres are cold.
The tyres are cold:
R if the vehicle has been parked with the tyres
out of direct sunlight for at least three hours
and
R if the vehicle has been driven less than
1.6 km
Depending on the ambient temperature, the
vehicle speed and the load on the tyres, the tyre temperature and thus the tyre pressure changes by approximately 10 kPa (0.1 bar/1.5 psi) per
10 †. Take this into account when checking the
pressure of warm tyres. Correct the tyre pres-
sure only if it is too low for the current operating
condition.
Driving with a tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are minimum values that offer you good driving
comfort characteristics.
However, you can also use the values given for
higher loads. These are permissible and will not
adversely affect the running of the vehicle. 338

Tyre pressure loss warning system
General notes While the vehicle is in motion, the tyre pressure
loss warning system monitors the set tyre pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in a tyre. If the rotational speed of
a wheel changes as a result of a loss of tyre
pressure, a corresponding warning message will
appear on the multifunction display.
You can recognise the tyre pressure loss warn-
ing by the Run Flat Indicator active
Run Flat Indicator active
Restart with OK Restart with OK message which appears in
the multifunction display in the Serv.
Serv.menu.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 339).
Important safety notes The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe the notes on the recommended tyre pressure
(Y page 337).
The tyre pressure loss warning system does not
replace the need to regularly check the tyre
pressure. 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 air, e.g. if the
tyre is penetrated by a foreign object. In this
event, bring the vehicle to a halt by braking
carefully. Avoid abrupt steering manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted on your vehicle
R road conditions are wintry
R you are driving on a loose surface (e.g. sand or
gravel)
R you adopt a very sporty driving style (corner-
ing 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 the vehi-
cle or on the roof) Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system if
you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres for
the respective operating conditions. The rec-
ommended tyre pressures can be found in the
tyre pressure table on the fuel filler flap.
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, this incorrect value will be
monitored.

Carefully depress the accelerator pedal and
make sure that the wheels do not spin when
driving on steep terrain.
If the load on the front axle is reduced when
pulling away on a steep uphill slope, the front
wheels have a tendency to spin. 4ETS recogni-
ses this and brakes the wheels accordingly. The
rear wheel torque is increased and it is easier to pull away.
