'M
Q ' (USA only) or M (Canada only): the red brake system warning lamp is
lit while the engine is running. Aw arning tone also sounds.
G WARNING
There is not enough brake fluid in the brake fluid reservoir.
The braking effect may be impaired.
There is ar isk of an accident.X
Pull over and stop the vehicle safely as soon as possible, paying attention to road
and traffic conditions. Do not continue driving under any circumstances. X
Secure the vehicle against rolling away ( Y
page 131).X
Do not add brake fluid. Adding more will not correct the malfunction. X
Consult aq ualified specialist workshop.X
Observe the additional display messages in the multifunction display.

Q USA only: the red brake system warning lamp is lit while the engine is running.
The multifunction display also shows ad isplay message with the & symbol.
The brake pads/linings have reached their wear limit. X
Visit aq ualified specialist workshop.
%
Q The yellow ABS warning lamp is lit while the engine is running.
ABS (anti-lock braking system) is malfunctioning.
If there is an additional warning tone, the EBD (electronic brake force distribution)
is malfunctioning.
Other driving systems and driving safety systems may also malfunction.
G WARNING
The brake system continues to function normally, but without the functions listed
above. The front and rear wheels could therefore lock if you brake hard, for exam-
ple.
The steerability and braking characteristics may be severely affected. The braking
distance in an emergency braking situation can increase.
If ESP ®
is not operational, ESP ®
is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident. X
Observe the additional display messages in the multifunction display. X
Drive on carefully. X
Visit aq ualified specialist workshop immediately.
If the ABS control unit is faulty, there is also ap ossibility that other systems, such
as the navigation system or the automatic transmission, will not be available.204

Pull the tire sealant bottle out of the tire infla-
tion compressor.
The filler hose remains attached to the tire
sealant bottle. X
Drive to the nearest qualified specialist work-
shop and have the tire changed there. X

Battery (vehicle)
Important safety notes Special tools and expert knowledge are required
when working on the battery, e.g. removal and
installation .Y ou should therefore have all work
involvin gt he battery carried out at aq ualified
specialist workshop.
G WARNING
Work carried out incorrectly on the battery
can lead, for example, to as hort circuit and
thus damage the vehicle electronics. This can
lead to function restriction sa pplying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-loc kb raking system) or the
ESP ®
(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example: R
when braking R
in the event of abrupt steerin gm aneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is ar isk of an accident.
In the event of as hort circuit or as imilar inci-
dent, contact aq ualified specialist workshop
immediately. Do not drive any further .Y ou
should have all work involvin gt he battery car-
ried out at aq ualified specialist workshop.
For further information about ABS and ESP ®
,
see ( Y
page 55) and ( Y
page 58). G WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of ab attery. There is ar isk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existin ge lectrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-start-
ing.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Ab uild-up of
electrostatic charge can be caused, for exam-
ple: R
by wearing clothin gm ade from synthetic
fibers R
due to friction between clothin ga nd seatsR
if you push or pull the battery across the car-
pet or other synthetic materials R
if you wipe the battery with ac loth
G WARNING
During the charging process, ab attery produ-
ces hydrogen gas. If as hort circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is ar isk of an explosion. R
Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts. R
Never place metal object sort ools on ab at-
tery. R
It is importan tt hat you observe the descri-
bed order of the battery terminals when
connectin ga nd disconnectin gab attery.R
When jump-starting, make sure that the
battery poles with identical polarity are
connected. R
It is particularly importan ttoo bserve the
described order when connectin ga nd dis-
connectin gt he jumper cables. R
Never connect or disconnect the battery
terminals while the engine is running.
G WARNING
Battery acid is caustic. There is ar isk of injury.246

Breakdown assistance

These tires have been specially adapted for
use with the control systems, such as ABS or
ESP ®
,a nd are marked as follows:R
MO = M ercedes-Benz OriginalR
MOE = M ercedes-Benz Original Extended
(tires featuring run-flat characteristics) R
MO1 = M ercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz .C ertain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with al oad, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components .T his
could result in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Information on tires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz ,s ince previ-
ous damage cannot alway sbed etected on
retreaded tires. As ar esult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if
you have no information about their previous
usage.
The recommended pressures for various oper-
ating conditions can be found: R
on the Tire and Loading Information placard
on the B-pillar on the driver's side R
in the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
( Y
page 258).
Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicle document wallet. Notes on the vehicle equipment –a lway se quip
the vehicle: R
with tires of the same size on ag iven axle (left
and right) R
with the same type of tires at ag iven time
(summer tires, winter tires, MOExtended
tires)
Exception: it is permissible to install ad iffer-
ent type or make in the event of af lat tire.
Observe t he
"MOExtended tires (tires with
run-flat characteristics" section ( Y
page 242).
Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefor er ecommended that you additionally
equip your vehicle with aT IREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. AT IREFIT kit may be obtained from
aq ualified specialist workshop.
