service indicator MERCEDES-BENZ C-CLASS CABRIOLET 2016 User Guide

If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified special- ist workshop, e.g. a Mercedes-Benz Service
Centre.
! Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Otherwise, components or systems could be
damaged.
! 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 on the
circuit and their functions will fail. Before replacing a fuse

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. 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 tire
pressure, a corresponding warning message will
appear in 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 Service
Service menu of the multifunction display.
Information on the message display can be
found in the "Restarting the tyre pressure loss
warning system" section (Y page 347).
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 345).
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 the
event of a sudden loss of air, 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
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.
