237 Practical hints
Flat tire
Detach the electric air pump.
The air hose may still be hot. Please ex-
ercise appropriate caution.
Store the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.
Close the trunk lid.
Drive away immediately.
The TIREFIT sealant will distribute itself
evenly inside the tire.
After driving vehicle for an initial
10 minutes, check tire pressure using
the pressure gauge on the air pump.
Warning!
G
Do not exceed vehicle speed of
50 mph (80 km / h). A TIREFIT repair is not
designed to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.
Warning!
G
If tire pressure has fallen below
20 psi (1.3 bar) do not continue to drive the
vehicle.
Park your vehicle safely away from the road-
way and contact the nearest authorized
Mercedes-Benz Center or Roadside Assis-
tance.
I f ti re pre s su re is a t l ea s t 2 0 ps i (1 .3 bar ), in -
flate tire to correct pressure (see label on
fuel filler flap), and drive vehicle to nearest
tire repair facility to have tire repaired or re-
placed.
Recommended duration of use:
300 miles (500 km) at 50 mph (80 km / h)
with the recommended tire pressure.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
244 Practical hintsFlat tire
Detach the electric air pump.
Reinstall tire valve cap.
Stow the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.
Close the trunk lid.Storing collapsible spare wheel in
wheel well
Before you can store the spare wheel with
collapsible tire in the wheel well you have
to release the air pressure of the tire.
Unscrew valve stem removal tool,
which is part of the valve cap, from tire
valve.
Using the valve stem removal tool,
open tire valve slightly by turning the
tire valve insert counterclockwise to
release air pressure.
When the air pressure has been re-
leased, remove tire valve insert (pro-
tect it from dirt and sand) using the
previously removed tire valve cap.
Once all air is out of the tire, and the
tire has collapsed to its original shape,
reinstall the tire valve insert and valve
cap.
Place spare wheel in wheel well and
secure it with the pump holder.

To prevent possible injury when unscrewing
air pump filler hose from tire valve after in-
flating the tire, use a rag since the tire valve
could be hot.
261 Technical data
Rims and Tires
Rims and Tires
Use only tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as
poor handling characteristics
increased noise
increased fuel consumption
!Moreover, tires and rims not approved
by Mercedes-Benz may, under load, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A tire inflation
pressure table is located on the fuel fill-
er cap of the vehicle. The tire pressure
should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.

273 Technical data
Fuels, coolants, lubricants etc.
Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.Coolants
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-
vides:
Corrosion protection
Freeze protection
Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil over-pro-
tection. You should have it replaced every
15 years or 150 000 miles (250 000 km),
whichever comes first. Coolant system de-
sign and coolant used stipulate the re-
placement interval. The above
replacement interval is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see Facto-
ry Approved Service Products pamphlet)
are used to renew the coolant concentra-
tion or bring it back up to the proper level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. -22°F [-30°C]). If you
use a solution that is more than 55% anti-
corrosion/antifreeze (freeze protection to
approx. -49°F [-45°C]), the engine temper-
ature will increase due to the lower heat
transfer capability of the solution. There-
fore, do not use more than this amount of
anticorrosion/antifreeze.If the coolant level is low, water and MB
Anticorrosion /Antifreeze should be used
to bring it up to the proper level (have cool-
ing system checked for signs of leakage).
Please make sure that the mixture is in ac-
cordance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult your authorized Mercedes-Benz
Center.
