The relative performance of tires depends upon
the actua lc onditions of their use ,h owever, and
may depart significantly from the norm du et o
variations in driving habits, service practices
and differences in road characteristics and cli-
mate.

MOE = M ercedes-Benz Original Extended
(tires featuring run-flat characteristics) R
MO1 = M ercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz .C ertain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with al oad, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components .T his
could result in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Information on tires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz ,s ince previ-
ous damage cannot alway sbed etected on
retreaded tires. As ar esult, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if
you have no information about their previous
usage.
The recommended pressures for various oper-
ating conditions can be found: R
on the Tire and Loading Information placard
on the B-pillar on the driver's side R
in the tire pressure table on the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
( Y
page 263).
Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicle document wallet. Notes on the vehicle equipment –a lway se quip
the vehicle: R
with tires of the same size on ag iven axle (left
and right) R
with the same type of tires at ag iven time
(summer tires, winter tires, MOExtended
tires)
Exception: it is permissible to mount ad iffer-
ent type or make in the event of af lat tire.
Observe t he
"MOExtended tires (tires with
run-flat characteristics)" section
( Y
page 247).
Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefor er ecommended that you additionally
equip your vehicle with aT IREFIT kit if you mount
tires that do not feature run-flat characteristics,
e.g. winter tires. AT IREFIT kit may be obtained
from aq ualified specialist workshop.

Important safety notes
G WARNING
The wheel or tire size as well as the tire type of
the spare wheel or emergenc ys pare wheel
and the wheel to be replaced may differ.
Mountin gane mergenc ys pare wheel may
severely impair the driving characteristics.
There is ar isk of an accident.
To avoid hazardous situations: R
adapt your driving style accordingly and
drive carefully. R
never mount more than one spare wheel or
emergenc ys pare wheel that differs in size. R
only use as pare wheel or emergenc ys pare
wheel of ad ifferent size briefly. R
do not switch ESP ®
off.R
have as pare wheel or emergenc ys pare
wheel of ad ifferent size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
When using an emergenc ys pare wheel or spare
wheel of ad ifferent size, you must not exceed
the maximum speed of 50 mph (80 km/h).Emergency spar ew heel 285

You shoul dr egularl yc heck the pressure of the
emergency spare wheel ,p ar ticularly prior to
long trips, and correct the pressure as neces-
sary ( Y
page 263). The value on the wheel is
valid.
An emergency spare wheel may also be moun-
ted against the direction of rotation. Observe
the time restriction on us easw el last he speed
limitation specified on the emergency spare
wheel.
Replace the tire sa fte rs ix years at the latest,
regardless of wear. Thi sa ls oa pplies to the
emergency spare wheel.
Whe ny ou are driving with the collapsibl es pare
wheel mounted, the tire pressure loss warning
system or the tire pressure monitor canno tf unc-
tion reliably. Only restart the tire pressure loss
warning system or tire pressure monitor when
the defectiv ew he el ha sb ee nr eplaced with a
new wheel.
Vehicles with tire pressure monitor: after
mounting an emergency spare wheel ,t he sys-
tem may stil ld is play the tire pressure of the
removed wheel for af ew minutes. The value dis-
played for the mounted emergency spare wheel
is not the same as the current tire pressure of
the emergency spare wheel.

The coolant is am ixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following: R
anti-corrosion protection R
antifreeze protection R
raising the boiling point
If the coolant has antifreeze protection dow nt o
-35 ‡( -3 7† ), the boiling point of the coolant
during operation is approximatel y2 66 ‡

Technical data Z

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should: R
be at least 50%. This will protec tt he engine
cooling system against freezin gd own to
approximately -35 ‡( -37 †).R
not exceed 55% (antifreez ep rotection down
to -49 ‡[ -45 †]). Otherwise, heat will not be
dissipated as effectively
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for Servic eP roducts
310.1.

fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB
WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps. ! Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The

Climate control system refrigerant
Important safety notes The climate control system of your vehicle is fil-
led with refrigerant R ‑ 134a.
The instruction label regarding the refrigerant
type 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 .O therwise, the climate
control system may be damaged.
Servic ew ork, such as refilling with refrigerant or
replacing component parts, may only be carried
out by aq ualified specialist workshop. All appli-
cable regulations, as well as SAE standard J639,
must be adhered to.
Always have work on the climate control system
carried out at aq ualified specialist workshop.294
