GWarning!
Do not exceed a 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
instrument cluster where it will be easily seen
by the driver.
Vehicle handling characteristics of a TIREFIT
repaired tire may change. Adapt your driving
accordingly.
XAfter driving for approximately 5 miles
(3 km) or 10 minutes, stop the vehicle and
check the tire inflation pressure using the
electric air pump.
i The TIREFIT sealing may impair the
function of the sensors in the tire. Proper
operating sensors are necessary to check
the tire inflation pressure with the
Advanced Tire Pressure Monitoring
System. When the sensors are not
operating properly, the measured tire
inflation pressure may be inaccurate or the
tire inflation pressure may not be displayed
at all. Error messages may appear.
Therefore, check and adjust the tire
inflation pressure with pressure gauge B
on the electric air pump.
GWarning!
If tire inflation pressure has fallen below
130 kPA (1.3 bar, 20 psi) do not continue to
drive the vehicle.
Park your vehicle safely away from the
roadway and contact the nearest authorized
Mercedes-Benz Center or Roadside
Assistance.
Have the damaged tire replaced.
If the tire inflation pressure is at least 130 kPA
(1.3 bar, 20 psi), inflate or deflate the tire to
the correct tire inflation pressure (see Tire
and Loading Information placard on the
driver’s door B-pillar):XTo increase tire inflation pressure:

Do not rub the battery with rags or cloths. The
battery could explode if touched due to
electrostatic charge or due to spark
formation.
! The battery is a Valve-Regulated Lead
Acid (VRLA) battery, also referred to as
“fleece” battery.
Such batteries do not require topping-up of
the electrolyte level. VRLA batteries
therefore do not have cell caps and the
battery cover is non-removable. Do not
attempt to open the battery as otherwise
the battery will be damaged.
VRLA batteries do not require topping-up of
the electrolyte level. They cannot be
opened to check the electrolyte level.
However, the battery condition must be
checked periodically by performing a
battery conductance test. Refer to

Jump startingGWarning!
Failure to follow these directions will cause damage to the electronic components, and can lead
to a battery explosion and severe injury or death.
Never lean over batteries while connecting or jump starting. You might get injured.
Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected area with water, and seek medical help if
necessary.
A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or
sparks away from battery, avoid improper connection of jumper cables, smoking, etc.
Attempting to jump start a frozen battery can result in it exploding, causing personal injury.
Read all instructions before proceeding.
! Do not tow-start the vehicle. You could otherwise seriously damage the transmission which
is not covered by the Mercedes-Benz Limited Warranty.
! Avoid repeated and lengthy starting attempts.
Do not attempt to start the engine using a battery quick-charge unit.
If the engine does not run after several unsuccessful starting attempts, have it checked at
the nearest authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated failed starting attempts may damage the
catalytic converter and may present a fire risk.
Make sure the jumper cables do not have loose or missing insulation.
Make sure the cable clamps do not touch any other metal part while the other end is still
attached to a battery.
If the battery is discharged, the engine can be started with jumper cables and the fully charged
battery of another vehicle or an equivalent starter pack. Observe the following:
R Access to the battery is not possible on all vehicles. If you cannot access the battery of the
other vehicle, provide jump start power by an external battery or starter pack.
R Jump starting should only be performed when the engine and catalytic converter are cold.
R Do not jump start the engine or charge the battery if the battery is frozen. Let the battery
thaw out first.
R Only jump start from batteries with the same voltage rating (12 V). Jump starting with a
more powerful battery could damage the vehicle’s electrical system. Such damage will not
be covered by the Mercedes-Benz Limited Warranty.
R Only use jumper cables with sufficient cross-section and insulated terminal clamps.
R Always make sure the jumper cables are not on or near pulleys, fans or other parts that
move when an engine is started or running.
R Should the battery be drained completely, let the donating power source charge the vehicle
for several minutes before reattempting the starting process.
The battery is located in the engine compartment on the passenger side.

Fuses
Introduction
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating.
GWarning!
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center.
A blown fuse must be replaced by an
appropriate spare fuse (recognizable by its
color or the fuse rating given on the fuse) of
the amperage recommended in the fuse
chart. Any Mercedes-Benz Center will be glad
to advise you on this subject.
i In case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-
Benz Center.
If a newly inserted fuse blows again, have the
cause determined and rectified by an
authorized Mercedes-Benz Center.
The fuse chart is located in the trunk with the
vehicle tool kit ( Y page 362). The fuse chart
explains the fuse allocation and fuse
amperages.

use of Mercedes-Benz approved additives is
recommended.
Contact an authorized Mercedes-Benz Center
or visit http://www.MBUSA.com (USA
only) for a listing of approved products.
Follow directions on the product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and may
be harmful to the engine operation.
! Damage or malfunction resulting from
poor fuel quality or from blending additional
fuel additives other than those tested and
approved by us for use on Mercedes-Benz
vehicles are not covered by the Mercedes-
Benz Limited Warranty or by any pre-owned
or Extended Limited Warranties.
Coolants
The engine coolant is a mixture of water and
anticorrosion/antifreeze, which provides:
R Corrosion protection
R Freeze protection
R Boiling protection (by increasing the boiling
point)
The cooling system was filled at the factory
with a coolant providing freeze protection to
approximately -35‡ (-37†) and corrosion
protection.
! Add premixed coolant solution only.
Adding water and MB 325.0 Anticorrosion/
Antifreeze separately from each other,
could cause engine damage not covered by
the Mercedes-Benz Limited Warranty.
If the antifreeze mixture is effective to -35‡
(-37†) , the boiling point of the coolant in the
pressurized cooling system is reached at
approximately 266‡ (130†).
The coolant solution must be used year round
to provide the necessary corrosion protection
and increase boil-over protection. Refer to
the Maintenance Booklet for replacement
interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze solution
or other Mercedes-Benz approved products
of equal specification are used to renew the
coolant concentration or bring it back up to
the proper level.
For information on other Mercedes-Benz
approved products of equal specification,
contact an authorized Mercedes-Benz Center
or visit http://www.MBUSA.com (USA
only).
To provide important corrosion protection,
the solution must be at least 50%
anticorrosion/antifreeze (equivalent to
freeze protection to approximately -35‡
[-37†]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protection
to approximately -49‡ [-45†]), the engine
temperature will increase due to the lower
heat transfer capability of the solution.
Therefore, do not use more than this amount
of anticorrosion/antifreeze.
If the coolant level is low, water and MB 325.0
Anticorrosion/Antifreeze should be used to
bring it up to the proper level (have cooling
system checked for signs of leakage). Please
make sure the mixture is in accordance 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,
contact an authorized Mercedes-Benz
Center.
Anticorrosion/antifreeze
Your vehicle contains a number of aluminum
parts. The use of aluminum components in
motor vehicle engines necessitates that
anticorrosion/antifreeze coolant used in
such engines be specifically formulated to
protect the aluminum parts. Failure to use
428Fuels, coolants, lubricants, etc.Technical data

such anticorrosion/antifreeze coolant will
result in a significantly shortened service life.
Therefore, the following product is strongly
recommended for use in your vehicle:
MB 325.0 Anticorrosion/Antifreeze agent.
Before the start of the winter season (or once
a year in hot southern regions), you should
have the anticorrosion/antifreeze
concentration checked.
The coolant is also regularly checked each
time you bring your vehicle to an authorized
Mercedes-Benz Center for service.Approximate freeze protection-35‡ (-37†)-49‡ (-45†)5.8 US qt (5.5 l)6.3 US qt (6.0 l)
