54 Getting startedDrivingSingle wipe
Press the combination switch briefly in 
direction of arrow1.
The windshield wipers wipe one time 
without washer fluid.
Wiping with windshield washer fluid
Push the combination switch in direc-
tion of arrow1 past the resistance 
point.
The windshield wipers operate with 
washer fluid.
For information on filling up the washer 
reservoir, see “Windshield washer system 
and headlamp cleaning system” 
(
page 278).
!If anything blocks the windshield 
wipers (leaves, snow, etc.), switch 
them off immediately.
For safety reasons,
turn off the engine by turning 
the SmartKey to position 0 and 
withdraw the SmartKey from 
the starter switch
or
turn off the engine by pressing 
the KEYLESS-GO* start/stop 
button and open the driver’s 
door (with the driver’s door 
open, the starter switch is in po-
sition 0, same as with the 
SmartKey removed from the 
starter switch)
before attempting to remove any 
blockage.
Remove blockage.
Turn the windshield wipers on 
again.
If windshield wipers fail to function at 
all in switch positionI,
set the combination switch to the 
next higher wiper speed
have the windshield wipers 
checked at the nearest authorized 
Mercedes-Benz Center

86 Safety and SecurityDriving safety systemsThe SBC brake system is automatically 
activated when you
unlock the vehicle with the SmartKey 
or the SmartKey with KEYLESS-GO*
open the driver’s or passenger door
turn the SmartKey in the starter switch 
to position1
in vehicles with KEYLESS-GO*, press 
the start/stop button on the gear se-
lector lever once
depress the brake pedal
release the parking brake
iIf the SBC brake system is activated as 
the brake pedal is first depressed, you 
may feel a reduced pedal resistance 
and longer pedal travel than normal. 
When releasing the pedal, you may also 
feel the brake pedal pulsate and you 
may hear a sound which is caused by 
the activation of the SBC brake system 
pump. This is normal and not an indica-
tion of a malfunction. Pedal travel re-
turns to normal when you release the 
brake pedal and the sound soon ceas-
es.
If you experience the above while driv-
ing and the red brake warning lamp 
(page 326) illuminates and/or warn-
ing messages appear in the multifunc-
tion display (
page 347), the brake 
system is malfunctioning. Follow the in-
structions of the warning message(s) 
and have the brake system checked 
immediately.
Warning!
G
Have brake pad replacement and other work 
on the SBC brake system carried out by 
qualified technicians only. Contact an au-
thorized Mercedes-Benz Center for further 
information. The SBC 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 acti-
vated when the vehicle is unlocked by re-
mote control, when the driver or passenger 
door is opened, when the SmartKey in the 
starter switch is turned to position1 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 mainte-
nance will cause brake pistons to extend 
and brake fluid to leak, which may result in 
injuries (contusions and acid burns). Extend-
ed brake pistons may also cause injury.

266 OperationDriving instructions
Coolant temperature
During severe operating conditions, e.g. 
stop-and-go city traffic, the coolant tem-
perature may rise close to approx. 266°F 
(130°C).
The engine should not be operated with 
the coolant temperature over 248°F 
(120°C). Doing so may cause serious en-
gine damage which is not covered by the 
Mercedes-Benz Limited Warranty.
Warning!
G
Inhalation of exhaust gas is hazardous to 
your health. All exhaust gas contains carbon 
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas 
(such as a garage) which are not properly 
ventilated. If you think that exhaust gas 
fumes are entering the vehicle while driving, 
have the cause determined and corrected 
immediately. If you must drive under these 
conditions, drive only with at least one win-
dow fully open at all times.
Warning!
G
Driving when your engine is badly over-
heated can cause some fluids, which 
may have leaked into the engine com-
partment, to catch fire. You could be se-
riously burned.
Steam from an overheated engine can 
cause serious burns and can occur just 
by opening the engine hood. Stay away 
from the engine if you see or hear steam 
coming from it. Turn off the engine, get 
out of the vehicle and do not stand near 
the vehicle until the engine has cooled 
down.

there is a malfunction in the SBC brake system.
There is insufficient brake fluid in the reservoir.
Release the parking brake

Read and observe messages in the 
display (

Risk of accident! Carefully stop the 
vehicle and notify an authorized 
Mercedes-Benz Center. Do not add 
brake fluid! This will not solve the 
problem.
Warning!
G
Driving with the brake warning lamp illumi-
nated can result in an accident. Have your 
brake system checked immediately if the 
brake warning lamp stays on. Do not add 
brake fluid before checking the brake sys-
tem. 
Overfilling the brake fluid reservoir can re-
sult in spilling brake fluid on hot engine 
parts and the brake fluid catching fire. You 
can be seriously burned.
!If you find that the brake fluid in the 
brake fluid reservoir has fallen to the 
minimum mark or below, have the 
brake system checked for brake pad 
thickness and leaks.
