The red ABS warning lamp is lit while the engine is running.
The ABS (Anti-lock Braking System) is malfunctioning.
An additional warning tone indicates that EBD (electronic brake force distribution) is malfunctioning.
Other driving and driving safety systems may also be malfunctioning.
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 may increase in an emergency braking situation.
If ESP ®
is not operational, ESP ®
is unable to stabilise the vehicle.
There is an increased risk of skidding and/or accident.
X Observe the additional display messages on the multifunction display.
X Drive on carefully.
X Consult aqualified specialist workshop immediately.
If the ABS control unit is faulty, there is also apossibility that other systems, such
as the navigation system or the automatic transmission, will be unavailable. !

WARNING
Work carried ou tincorrectly on the battery
can lead, for example, to ashort circui tand
thus damage the vehicl eelectronics. This can
leadtof unction restrictions applying to
safety-relevant systems ,e.g the lighting sys-
tem, the ABS (anti-lock braking system) or the

R when braking
R in the event of abrupt steering manoeuvres
and/or when the vehicle's spee disnot

There is arisk of an accident.
In the event of ashort circui torasimilar inci-
dent, contact aqualified specialist workshop
immediately. Do not drive any further. Always have work on the battery carrie dout at a

Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Electrostatic
charge is created, for example:
R by wearing synthetic-fibre clothing
R by friction between clothing and the seat
R if you pull or push the battery across carpet or
other synthetic materials
R if you rub the battery with acloth G
WARNING
During the charging process, abattery produ-
ces hydrogen gas. If ashort circui toccurs or
sparks are created ,the hydrogen gas can
ignite. There is arisk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicl eparts.
R Never place metal objects or tools on abat-
tery.
R It is important that you observe the descri-
bed order of the battery terminal swhen
connecting and disconnecting abattery.
R When jump-starting, make sure that the
battery pole swith identical polarity are
connected.
R It is particularl yimportant to observe the
described order when connecting and dis-
connecting the jump leads.
R Never connect or disconnect the battery
terminal swhile the engine is running. G
WARNING
Battery acid is caustic. There is arisk of injury.

You can ask for information regarding permitted
wheel/tyre combinations at aMercedes-Benz
Service Centre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres, wheels and
accessories which have been approved by
Mercedes-Benz for you rvehicle. These are
speciall yadapted to the various driving safety
systems, such as ABS or ESP ®
.
Only use the tyres, wheels and accessories
tested and recommende dbyMercedes-Benz.
Certain characteristics, such as handling,
vehicl enoise emissions, fuel consumption,
etc. may otherwise be adversely affected.
Other wheel sizes may caus ethe tyres to
come into contact with the vehicl ebody and
axle components, whe nunder load. This may
result in damage to the tyre or the vehicle.
Mercedes-Benz is not responsibl efor any
damage caused by using tyres, wheels or
accessories other than those recommended.
Informatio nontyres, wheels and permissible
combinations can be obtained at aqualified
specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommende dbyMercedes-Benz, since previ-
ous damage cannot alwaysbed etected on
retreaded tyres. As aresult, Mercedes-Benz
cannot guarantee vehicl esafety if retreaded
tyres are fitted. Do not fit use dtyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Rol lcomfort
and suspension comfort are reduced and the risk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommende dtyre pressures for various
operating conditions can be found on the tyre 246

G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to aheavy load. This would impair brak-
ing efficiency. There is arisk of an accident.
Have the brake flui drenewe datthe prescri-
bed intervals.
Comply with the important safety notes for ser- vice products when handling brake fluid
(Y page2 50).
Only use brake flui dapproved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0.
Information about approved brake flui dcan be
obtained at any qualified specialist worksho por

WARNING
If antifreeze come sinto contact with hot com-
ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool downb efore you top up
the antifreeze .Make sure that antifreeze is
not spilled next to the filler neck. Thoroughly
clea nthe antifreeze from components before
starting the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
coul dotherwise damage the engine.

The coolant is amixture of water and anti-
freeze/anti-corrosion additive. It is responsible
for the following:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosio ninhibitor is present in the
correct concentration, the boiling point of the
coolant willbea round 130 †. Service products and capacities
