Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and lead to death. Do not
run the engine in confined areas (such as a
garage) which are not properly ventilated.Display messagesPossible causes/consequences and 0050 Solutions0026Brake WearThe brake pads have reached their wear limit.XHave the brake pads replaced as soon as possible.
!
Brake pad thickness must be visually inspected by a qualified technician at the intervals
specified in the Maintenance Booklet.
GWarning!
Have brake pad replacement and other work
on the electro-hydraulic brake system carried
out by qualified technicians only. Contact an
authorized Mercedes-Benz Center for further
information.
The electro-hydraulic brake system must be
deactivated prior to working on the system.
High pressure is intermittently built up in the
system as part of its automatic self-test.
In addition, the system is automatically
activated when the vehicle is unlocked by
remote control, when the driver or passenger
door is opened, when the SmartKey in the
starter switch is turned to position 1 or the
KEYLESS-GO start/stop button is pressed
once, when the brake pedal is depressed or
when the parking brake is released. Failure to
deactivate the system prior to maintenance
will cause brake pistons to extend and brake
fluid to leak, which may result in injuries
(contusions and acid burns). Extended brake
pistons may also cause injury.238Vehicle status messages in the multifunction displayPractical hints

Replacing wiper blades
Safety notes
GWarning!
For safety reasons, switch off the wipers and
remove the SmartKey from the starter switch
(vehicles with KEYLESS-GO: Make sure the
vehicle’s on-board electronics have status 0)
before replacing a wiper blade. Otherwise, the
wiper motor could suddenly turn on and cause
injury.
GWarning!
Wiper blades are components that are subject
to wear and tear. Replace the wiper blades
twice a year, preferably in the spring and fall.
Otherwise the windshield will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.
! To avoid damage to the hood, the wiper
arms should only be folded forward when
in the vertical position.
! Never open the hood when a wiper arm is
folded forward.
Hold on to the wiper when folding a wiper
arm back. If released, the force of the
impact from the tensioning spring could
crack the windshield.
Do not allow a wiper arm to contact the
windshield glass without a wiper blade
inserted.
Mercedes-Benz recommends that you have
this work carried out at an authorized
Mercedes-Benz Center.
