iWhen a Tele Aid call has been initiated,
the audio system or the COMAND* sys-
tem audio is muted and the selected
mode (radio, tape or CD) pauses. The
optional cellular phone (if installed)
switches off. If you must use this
phone, the vehicle must be parked. Dis-
connect the coiled cord and place the

A pop-up window will appear in the CO-
MAND* display to indicate that a
Tele Aid call is in progress.

243 Operation
Tires and wheels
Life of tire
The service life of a tire is dependent upon
varying factors including but not limited to:

Driving style


Tire pressure


Distance driven
Direction of rotation
Unidirectional tires offer added advantag-
es, such as better aquaplaning perfor-
mance. To benefit, however, you must
ensure that the tires rotate in the direction
specified.
An arrow on the sidewall indicates the in-
tended direction of tire rotation.Checking tire inflation pressure
Regularly check your tire pressure at inter-
vals of no more than 14 days.
Correct the tire pressure only when tires
are cold.If the tires are warm you should only cor-
rect the tire pressure if it is too low for cur-
rent operating conditions.
A table on the fuel filler flap lists the spec-
ified tire inflation pressures for warm and
cold tires as well as for various operating
conditions.
Tire pressure changes by approx. 1.5 psi
(0.1 bar) per 18°F (10°C) of air tempera-
ture change.
Warning!
G
Tires and spare tire should be replaced after
six years, regardless of the remaining tread.!Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease and gasoline.
Warning!
G
If the tire pressure repeatedly drops

check the tires for punctures from for-
eign objects


check to see whether air is leaking from
the valves or from around the rim
iThe pressures listed for light loads are
minimum values offering high driving
comfort.
Increased inflation pressures listed for
heavier loads may also be used for light
loads. These higher pressures produce
favorable handling characteristics. The
ride of the vehicle, however, will be
somewhat harder. Never exceed the
max. values or inflate tires below the
min. values listed in the fuel filler flap.

Vehicle care
Vehicle care
Cleaning and care of vehicle
While in operation, even while parked, your
vehicle is subject to varying external influ-
ences which, if gone unchecked, can at-
tack the paintwork as well as the
underbody and cause lasting damage.
Such damage is caused not only by ex-
treme and varying climatic conditions, but
also by:

Air pollution


Road salt


Tar, gravel and stone chippingTo avoid paint damage, you should imme-
diately remove:


Grease and oil


Fuel


Coolant


Brake fluid


Insects


Tree resins etc.
Frequent washing reduces and / or elimi-
nates the aggressiveness and potency of
the above adverse influences.
More frequent washings are necessary to
deal with unfavorable conditions:


Near the ocean


In industrial areas (smoke, exhaust
emissions)


During winter operationYou should check your vehicle from time to
time for stone chipping or other damage.
A n y d a m a g e s h o u l d b e r e p a i r e d a s s o o n a s
possible to prevent corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.
Your vehicle has been treated at the facto-
ry with a wax-base rustproofing in the body
cavities which will last for the lifetime of
the vehicle. Post-production treatment is
neither necessary nor recommended by
Mercedes-Benz because of the possibility
of incompatibility between materials used
in the production process and others ap-
plied later.
We have selected car-care products and
compiled recommendations which are
specially matched to our vehicles and
which always reflect the latest technology.
You can obtain Mercedes-Benz approved
car-care products at your authorized
Mercedes-Benz Center.
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or solvents that are not de-
signed for cleaning your vehicle.

Replacing bulbs
Rear lamps Notes on bulb replacement


Use only 12 volt bulbs of the same type
and with the specified watt rating.


Switch lights off before changing a bulb
to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not light
up, visit an authorized Mercedes-Benz
Center.


Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized
Mercedes-Benz Center:

Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas.
A bulb can explode if you

touch or move it when hot


drop the bulb


scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.

332 Technical dataFuels, coolants, lubricants etc.Engine oils
Engine oils are specifically tested for their
suitability in our engines. Therefore, use
only engine oils recommended by
Mercedes-Benz. Information on
recommended brands is available in the
Factory Approved Service Products pam-
phlet, or at your authorized Mercedes-Benz
Center.
Please follow FSS recommendations for
scheduled oil changes. Failure to do so
could result in engine damage not covered
by the Mercedes-Benz Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil.
They may be harmful to the engine opera-
tion.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil is used in the air condition-
ing system.
Never use R-12 (CFC) or mineral-based
lubricating oil, otherwise damage to the
system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere. Under extremely strenu-
ous operating conditions, this moisture
content can lead to the formation of bub-
bles in the system, thus reducing the sys-
tem’s efficiency.
Therefore, the brake fluid must be
replaced every two years, preferably in the
spring.
Only brake fluid approved by
Mercedes-Benz is recommended. Your
authorized Mercedes-Benz Center will
provide you with additional information.
