Ypage 276).
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
tire pressure is incorrect. Observe the notes on
the

Dependin gonthedrivin gstyle, th evehicl econ-
sumes amaximum of 1. 0USqt(1.0l )ofe ngine
oil over adistance of 620 miles (1,000 km).
Oil consumption may be higher if:
Rthe vehicle is new.
Ryou mainly operate the vehicle under arduous
operating conditions.
Ryou frequently drive at high engine speeds.
Regularm aintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven aconsiderable distance.
Check the engine oil level on aregular basis, e.g.
weekly or each time you refuel (

the brake fluid .Ifthe boiling point of the brake
fluid is too low, vapor pockets may form in the

Coolan tadditive with corrosion and
antifreeze protection
!Use only approved antifreeze/corrosion
inhibitor that complies withMBS pecification
300Service products and capacities
Technical data
for Service Products, Sheet Number 325.
Using other, non-approved antifreeze/corro-
sion inhibitors may causedamage to the cool-
ant system and reduce the engine' sservice
life

.
The coolant is amixture of water and antifreeze
and corrosion inhibitor. It performs the following
tasks:
Rcorrosion protection
Rantifreeze protection
Rraises the boiling point
When the vehicl eisfirst delivered, it is filled with
ac oolant mixture that ensure sadequate anti-
freeze and corrosion protection. Coolant must
remai ninthe engine cooling system all year
round to ensure anti-corrosion protection and a
higher boiling point, even in countries with high
outside temperatures.
To prevent damage to the engine cooling sys-
tem, use only approved antifreeze and corrosion
inhibitor that complies with the Mercedes-Benz Specifications for Service Products.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the requirements
in the Mercedes-Benz Specifications for Service
Products Sheet Number 325.
Check the antifreeze/corrosio ninhibitor con-
centration in the coolant every six months.
The percentag eofcorrosion inhibitor/anti-
freeze additive in the engine cooling system
should:
Rbe at least 50%. This way, the engine cooling
system is protected against freezing downt o
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡[-45 †]) .Otherwise, hea twilln ot be
dissipated as effectively.
If ther ehasbeen coolant loss, do not refill only
with water. If the vehicl ehaslost coolant, add
equa lparts water and antifreeze/corrosion
inhibitor. The water used as part of the coolant
mixture must fulfil lcertain requirements; these
are usuall yfulfille dbyd rinking water. If the
water quality is not sufficient, yo umusttrea tthe
water.

Clim ate control systemr efrigerants
Important safety notes
The climate control system of you rvehicle is fil-
led with the refrigerant R ‑134a.
The warning label for the refrigerant being used
can be found on the radiator cross member.
!Only the refrigerant R ‑134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. Otherwise ,the climate
control system may be damaged.
Maintenance work such as adding refrigerant or
replacing components may only be carried out
by aq ualified specialist workshop. All applicable
regulations thereto and the SAE standard J639
need to be respected.
All work on the climate control system should
always be carried out at qualified specialist
workshop.
