!Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
Example: cap and coolant expansion tank
Checkingt he coolant level
XStop your vehicle as far awayf rom traffic as
possible on level ground.
XSwitch off the engine.
XSecure the vehicle to prevent it from rolling
away.
XOpen the hood (Ypage 241).
XSlowly turn cap :half aturn counter-clock-
wise to allow excess pressure to escape.
XTurn cap :further and remove it from cool-
ant expansion tank ;.
XCheck the coolant level.
If the coolant is up to marker bar =in the
filler neck when cold, there is asufficient
amount of coolant in coolant expansion
tank ;.
If the coolant is approximately 0.59 in
(1.5 cm) above marker bar =in the filler neck
when warm, there is asufficient amount of
coolant in coolant expansion tank ;.
Adding coolant
XIf the coolant drops under marker bar =in
the filler neck, add coolant.
Observe the information on the correct cool-
ant mixture ratio and the required water qual-
ity under "Service products and capacities"
(
Ypage 300). To prevent damage to the
engine cooling system, use only approved
corrosion inhibitor/antifreeze that complies
with the Mercedes-Benz Specifications for
Service Products.
XReplace cap :and turn it clockwise to
tighten.
XStart the engine.
XSet the temperature in the vehicle interior to
the maximum output on the air-conditioning
system control panel.
XAfter approximately 5minutes ,switch off the
engine and allow it to cool down.
XCheck the coolant level againa nd add coolant
if necessary.
XClose the hood.

Let an overheated engine cool down before
opening the hood. If there is afire in the
engine compartment,k eep the hood closed
and contact the fire department.
GWARNING
Certain componentsint he engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible,l et the engine cool down and
touch only the componentsd escribed in the

Important safety notes
GWARNING
Each tire, including the spare (ifp rovided),
should be checked at least once amonth
whe ncold and inflated to the pressure rec-
ommended by the vehicle manufacturer on
the Tir eand Loading Information placard on
the driver's doo rB-pilla rort he tire pressure
label on the inside of the fue lfiller flap. If your
vehicle has tires of adifferent size than the
size indicated on the Tir eand Loading Infor-
mation placard or the tire pressure label ,you
should determine the proper tire pressure for
those tires.
As an added safety feature ,you rv ehicle has
bee nequipped with atire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sur etelltal ewheno ne or more of your tires
are significantly underinflated. Accordingly,
whe nthe low tire pressure telltal eillumi nates,
yo us hould stop and check your tires as soon
as possible, and inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire causes the tire to overheata nd can
lea dtot ire failure. Underinflation also
reduce sfue lefficiency and tire treadl ife, and
may affect the vehicle' shandling and stop-
ping ability.
Please note that the TPMSisn otas ubstitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMSl ow tire pressure telltale.
USA only:
You rvehicle has also bee
nequipped with a
TPM
Sm alfunction indicator to indicate if the
system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. Whe nthe system
detects amalfunction, the warning lamp will
flash for approximately aminute and then
remain continuously illuminated. This
sequence will be repeated ever ytime the vehi-
cle is starte daslong as the malfunction
exists.
Whe nthe malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMSm alfunc-
tions may occur for avariety of reasons,
including the mounting of incompatible
replacement or alternate tires or wheels on
the vehicle that prevent the TPMSf rom func-
tioning properly. Alway scheck the TPMSm al-
function telltal eafterreplacing one or more
tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMStoc ontinuetofunction prop-
erly.
It is the driver's responsibility to set the tire
pressure to the recommende dcold tire pressure
suitabl efor the operating conditions
(
Ypage 270).
Note that the correct tire pressure for the cur-
rent operating conditions mus tfirs tb ep ro-
gramed into the tire pressure monitor. If there is
as ubstantial los sofpressure, the warning
threshol dfor the warning messag eisaligne dto
the reference value sprograme din. Restart the
tire pressure monito rafte radjusting the cold
tire pressure (
Ypage 277). The current pres-
sures are saved as new reference values. This
will ensure that awarning messag ewillo nly
appea rifthe tire pressure drop ssignificantly.
The tire pressure monito rdoesn ot warn yo uifa

the
