vertical position before folding them away
from the windshield. They could otherwise
damage the hood.
Never open the hood when the wiper arms
are folded forward.
XMake sure the hood is fully closed.XSwitch on the ignition.XTurn combination switch to wiper setting
II (Y page 95).XWith wiper arms in vertical position, switch
off the ignition.GWarning!
For safety reasons, switch off wipers and
remove SmartKey from starter switch before
cleaning the windshield and/or the wiper
blades. Vehicles with KEYLESS-GO: Make
sure the vehicle’s on-board electronics have
status 0. Otherwise, the wiper motor could
suddenly turn on and cause injury.
! Do not pull on the wiper blade inserts.
They could tear.
XFold the wiper arms forward until they snap
into place.XClean the windshield and the wiper blade
inserts with a clean cloth and mild

containing solvents. Do not touch the
inside of the windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.

Inhalation of exhaust gas is hazardous to your

unconsciousness and lead to death. Do not
run the engine in confined areas (such as a

!
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

GWarning!
Driving when your engine is overheated can cause some fluids which may have leaked into the
engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until the engine has cooled down.
! The engine should not be operated with the coolant temperature above 248‡ (120†).
Doing so may cause serious damage which is not covered by the Mercedes-Benz Limited
Warranty.
