2018 MERCEDES-BENZ E-CLASS WAGON overheating

The probability of a serious oreven fata l acci‐
dent greatly inc reases if youdriv e when
under the influence of alcohol or drugs.
#Do not drink alcohol or take drugs while
driving, and do not allow an yone to
drive who has been drinking alcohol or

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.

#If tire sealant has been swallowed,
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.
*NO
TEOverheating due tothe tire infla‐
tion compressor running too long
#Do not runth e tire inflation compressor
fo r longer than ten minu tes without
inter ruption.
Comply with the manufacturer's saf etyno tes in

RThe tires maywearexc essively and/or
une venly, which may greatlyimpair tire
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-
ro ad driving
#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
all the tires, including the spare wheel.
Excessively high tire pressure can result in:
RIncreased braking dis tance
RImpaired handling characteristics
RIrre gular wear
RImpaired driving com fort

TEOverheating at high outside tem‐
peratures
If an inappro priate coolant is used, the
engine cooling sy stem is not suf ficiently pro‐
te cted against overheating and cor rosion at
high outside temp eratures.
#Alw ays use coolant appr ovedby

#Obser vethe instructions in the
Mercedes-Benz Specifications for Oper‐
ating Fluids 310.1.
Ha ve the coolant regularly changed at a qualified
specialist workshop.
The proportion of cor rosion inhibitor/antifreeze
concentrate in the engine cooling sy stem should
be:
RA minimum of 50% (antifreeze pr otection
down toappr oximately -35 °F (-37 °C)).
