The probability of a serious oreven fata l acci‐
dent greatly inc reases if youdriv e when
under the influence of alcohol or drugs.

WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the
brake sy stem may evenfa il.
#Ne ver use the brake pedal as a foot re st.
#Do not depress the brake pedal and the
accelerator pedal at the same time
while driving.
* NO
TEWearing out the brake linings by
continuously dep ressing the brake pedal
#Do not depress the brake pedal contin‐
uously whilst driving.
#To use the braking ef fect of the engine,
shift toa lo werge ar in good time.
* NO
TEDama getothe driv etra in and the
engine when pulling away
#Do not warm upthe engine when the
ve hicle is stationar y.Pull away immedi‐
atel y.
#Avoid high engine speeds and driving at
full thro ttle until the engine has reached
operating temp erature.
#Do not allow the wheels tospin.
* NO
TEDama getothe catalytic con verter
due tonon-combu sted fuel
The engine is not running smoot hly and is
misfiring.
Non-combus ted fuel may get into the cata‐
lytic con verter.
#Only depress the accelera tor pedal
slightl y.
#Have the cause rectified immediately at
a qu alified specialist workshop.
Limited braking ef fect on salt-treate dro ads:
RDue tosalt build-up on the brake discs and
brake lining, the braking dis tance can
increase conside rably or result in braking
only on one side.
RMaintain a much greater dis tance totheve hi‐
cle in front.
To preve nt salt build-up:
RBrake occasionally while paying attention to
th e tra ffic conditions.
RCarefully depress the brake pedal at the end
of the journey and when starting the next
journe y.

&WARNING Risk of injury and poisoning
from tire sealant
The tire sealant is harmful and causes ir rita ‐
tion. Do not allow it tocome into contact
wi th th e skin, eyes or clo thing, and do not
swallow it. Do not inhale tire sealant fumes.
Ke ep the tire sealant away from children.
If yo u come into contact withth e tire sealant,
obser vethefo llowing:
#Rinse off the tire sealant from your skin
immediately using water.
#If tire sealant gets into your eyes, thor‐
oughly rinse out theey es using clean
wate r.
#If tire sealant has been swallowe d,
immediately rinse out the mouth thor‐
oughly and drink plenty of water.Do not
induce vomiting and seek medical
attention immediately.
#Change out of any clo thes conta mina‐
te d with tire sealant immediatel y.
#If allergicreactions occur, seek medical
attention immediatel y.

traction.
RThe driving characteristics, as well as
st eering and braking, may be greatly
impaired.
#Comply with there commended tire
pressure and check the tire pressure of
all tires including the spare wheel regu‐
larly:
Rat least once a month
Rwhen the load changes
Rbefore embarking on a longe r journey
Rif operating conditionschange, e.g. off-

#Ad just the tire pressure as necessar y.
Driving withtire pressure that is too high or too
low can:
RSho rten the service life of the tires.
RCause increased tire damage.
RAd versely af fect handling characteristics and

&
WARNING Risk of an accident due to
insuf ficient tire pressure
Ti re s with pressure that is too low can over‐
heat and bur stas a result.
In addition, they also suf fer from excessive
and/or ir regular wear, which can significantly
impair the braking properties and the han‐
dling characteristics.
#Av oid excessively low tire pressures in
all the tires, including the spare wheel.
Tire pressure which is too low can cause:
RTire defects as a result of overheating
RImpaired handling characteristics
RIrre gular wear
RIncreased fuel consum ption
&
WARNING Risk of accident from exces‐
sive tire pressure
Ti re s with excessively high pressure can
burs t because they are damaged more easily
by highw ayfill, pot holes etc.
In addition, they also suf fer from ir regular
we ar, which can significantly impair the brak‐
ing properties and the handling characteris‐
tics.
#Av oid excessively high tire pressures in

The relative per form ance of tires depends upon
th e actual conditions of their use, ho wever,and
may depart significantly from the norm due to

DANG ER Risk of accident due toinade‐
qu ate traction
The traction grade assigned tothis tire is
based on stra ight-ahead braking traction
te sts, and does not include either accelera‐
tion, cornering, hydroplaning or peak traction
ch aracteristics.

The traction grades – from highest tolowest –
are AA, A,B and C. Those grades represent the
tire's ability tostop on wet pa vement as meas‐
ured under controlled conditions on specified
go vernment test sur faces made of asphalt and
concr ete.
Te mp erature grade
&
WARNING Risk of accident from tire
ove rheating and tire failure
The temp erature grade forth is tire is es tab‐
lished for a tire that is proper ly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately
or in combination, can cause excessive heat
build-up and possible tire failure.
#Obser vethere commended tire pres‐
sure s and regularly check the tire pres‐
sure of all tires including the spare
wheel.
#Ad just the tire pressure as necessar y.
Thetemp erature grades are A (the highest), B
and C. They represent the tire's resis tance tothe
ge neration of heat and its ability todissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel. Sus‐
ta ined high temp erature can cause the material
of the tire todegenerate and reduce tire life, and
exc essive temp erature can lead tosudden tire
fa ilure. Grade C cor responds toa le vel of per‐
fo rm ance which all passenger car tires must
meet under therequ irements of the US Depart‐
ment of Transpor tation.

US tire regulations stipulate that eve rytire man‐
ufactu rer or retreader must imprint a TIN in or
on the side wall of each tire produced.

Notes on brake fluid
Obser vethe no tes on operating fluids
(→page 447).
&
WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
te m
The brake fluid cons tantly absorbs moist ure
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be
impaired.
#Ha ve the brake fluid rene we d at the
specified inter vals.
Ha ve the brake fluid regularly changed at a quali‐
fi ed specialist workshop.
Only use brake fluid appr ovedby Mercedes-Benz
according toMB-F reigabe or MB-Appr oval 33 1.0. Fu
