Data stored in the vehicle
Data storage
A wide range of electronic components in your
vehicle contain data memories. These data memories temporarily or perma-
nently store technical information about:
Rthe vehicle's operating state
Rincidents
Rmalfunctions
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
Roperating conditions of system components,
e.g. fluid levels
Rthe vehicle's status messages and those of its
individual components, e.g. number of wheel
revolutions/speed, deceleration in move-
ment, lateral acceleration, accelerator pedal
position
Rmalfunctions and defects in important system
components, e.g. lights, brakes
Rvehicle reactions and operating conditions in
special driving situations, e.g. air bag deploy-
ment, intervention of stability control sys-
tems
Rambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to:
Rassist in recognizing and rectifying malfunc-
tions and defects
Ranalyze vehicle functions, e.g. after an acci-
dent
Roptimize vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memor
y
and malfunction data memory.
Services include, for example:
Rrepair services
Rservice processes
Rwarranties
Rquality assurance
The vehicle is read out by employees of the ser-
vice network (including the manufacturer) using
special diagnostic testers. More detailed infor-
mation is obtained from it, if required.
After a malfunction has been rectified, the infor-
mation is deleted from the malfunction memory or is continually overwritten.

Windshield wipers
Switching the windshield wipers
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.

GWARNING
Limbs could be crushed or trapped if the
engine is started unintentionally during ser-
vice or maintenance work. There is a risk of
injury.
Always secure the engine against uninten-
tional starting before carrying out mainte-
nance or repair work.
Make sure that the engine cannot be started via
your smartphone before carrying out mainte-
nance or repairs. You can prevent an engine
start via your smartphone, for example, if you:
Rswitch on the hazard warning lamps
Rdo not lock the doors
Ropen the hood
Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (
Ypage 196).
It is possible to shift the transmission from posi-
tion jto the desired position only if you
depress the brake pedal. Only then can the
parking lock be deactivated.
All vehicles (except Mercedes-AMG vehi-
cles): if you do not depress the brake pedal, the
DIRECT SELECT lever can still be moved but the parking lock remains engaged. Mercedes-AMG vehicles:
if you do not depress
the brake pedal, the selector lever can still be
moved but the parking lock remains engaged.
At transmission fluid temperatures below Ò4 ‡
(Ò20†), you can only shift out of position jinto
another transmission position when the engine
is running.
iUpshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.
Information on the automatic release of the
electric parking brake (
Ypage 145).
Hill start assist
Hill start assist helps you when pulling away
forward or in reverse on an uphill gradient. It
holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
Ryou are pulling away on a level road or on a
downhill gradient.
Rthe transmission is in position i.
Rthe electric parking brake is applied.
RESP®is malfunctioning.
Further information on holding the vehicle sta-
tionary on uphill gradients (
Ypage 136).

Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
RIn order to prevent any salt build-up, apply the
brakes occasionally while paying attention to the traffic conditions.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up in
the instrument cluster and
Ryou hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately.
Consult a qualified specialist workshop to
arrange this.
!A function or performance test should only
be carried out on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult a qualified spe- cialist workshop in advance. You could oth-
erwise damage the drive train or the brake
system.
!As the ESP®system operates automatically,
the engine and the ignition must be switched
off (the SmartKey must be in position uor
1 in the ignition lock), if the electric parking
brake is tested on a braking dynamometer
(maximum 10 seconds).
Braking triggered automatically by ESP
®may
cause severe damage to the brake system.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop. If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals.
You can find a description of Brak
e Assist (BAS)
on (Ypage 61).
Mercedes-Benz recommends that you only have
brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which have
not been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake
fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
Checking brake lining thickness
You can measure the break pad/lining thick-
ness using a test gage. Color-coding (green or
red) on the test gage allows you to determine
whether the brake pad/lining thickness is still
sufficient. The test gage is in the vehicle docu-
ment wallet in the glove box.
