244 Operation
Driving instructions
Telephones and two-way radios
Radio transmitters, such as a portable
telephone or a citizens band unit should
only be used inside the vehicle if they are
connected to an antenna that is installed
on the outside of the vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna.Catalytic converter
Your Mercedes-Benz is equipped with
monolithic-type catalytic converters, an
important element in conjunction with the
oxygen sensors to achieve substantial
control of the pollutants in the exhaust
emissions. Keep your vehicle in proper
operating condition by following our
recommended maintenance instructions
as outlined in your Maintenance Booklet.
Warning!G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system,
possibly resulting in an accident and
personal injury.
!To prevent damage to the catalytic
converters, only use premium unleaded gasoline
in this vehicle.
Any noticeable irregularities in engine operation
should be repaired promptly. Otherwise exces-
sive unburned fuel may reach the catalytic
converter, causing it to overheat and potentially
start a fire.
Warning!G
As with any vehicle, do not idle, park or
operate this vehicle in areas where combus-
tible materials such as grass, hay or leaves
can come into contact with the hot exhaust
system, as these materials could be ignited
and cause a vehicle fire.
Warning!G
The exhaust areas on the engine hood and
between the doors and front wheels get very
hot. Avoid contact with them, otherwise
there is the risk of severe burns.

270 Operation
Tires and wheels
The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in tire inflation pressure in one or
more of the tires.
Tire pressure inquiries are made using the
multifunction display. The present inflation
pressures are displayed only after a few
minutes’ travel time.
Switch on the ignition (page 40).
Press button è or ÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(
page 122).
Press button k or j repeatedly
until the current tire inflation pressures
for each tire appear in the multi-
function display.
iPossible differences between the readings
of a tire inflation pressure gauge of an air hose,
e.g. gas station equipment, and the vehicle’s
control system can occur. The readings issued
by the control system are more precise.
iWhen the message Tire pressure
displayed only after driving a few
minutes
appears in the multifunction display,
the individual inflation pressure values are
matched with the tires. The individual values are
displayed after a few minutes driving.
Warning!G
It is the driver’s responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might lose control over the vehicle.
Warning!G
The TPMS does not indicate a warning for
wrongly selected inflation pressures. Always
adjust tire inflation pressure according to
the placard on the driver’s door B-pillar
(
page 267) or, if available, the supple-
mental tire pressure information on the
inside of the fuel filler flap.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of tire inflation
pressure (e.g. tire blowout caused by a for-
eign object). In this case bring the vehicle to
a halt by carefully applying the brakes and
avoiding abrupt steering maneuvers.

296 Operation
Vehicle care
Vehicle washing
Hand-wash
Do not use hot water or wash your vehicle
in direct sunlight.
Only use a mild car wash detergent,
which is recommended by
Mercedes-Benz.
Only use a soft sponge or a washing
brush.
Thoroughly spray the vehicle with a
diffused jet of water.
Direct only a very weak spray towards
the ventilation intake.
Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.
Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are
preferable.
To protect the filter system, switch the
automatic climate control to air
recirculation mode (
page 195).
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.!When washing the vehicle, fine and rigid
particles in sponges or brushes could scratch or
otherwise damage the paint. This applies to
both, hand-wash or automatic car wash.
Mercedes-Benz recommends you to have your
vehicle cleaned at an automatic car wash from
the start, preferably one without brushes, or to
use plenty of water when hand-washing your
vehicle.
Do not wash the car in direct sunlight and when
the body surface is hot.
In the winter, remove salt residue quickly and
thoroughly.
!Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the paint.
!Do not clean your vehicle in an automatic
touchless car wash which uses caustic spray.
Otherwise, the caustic spray will damage the
paint or ornamental moldings.
!Make sure that the windshield wiper switch
is set to0 (
page 52). Otherwise, the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 297). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.

Sealing tires with TIREFIT
Small tire punctures, particularly those in
the tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient tempera-
tures down to -4°F (-20°C).
Foreign objects (e.g. screws or nails)
should not be removed from the tire.
Take TIREFIT, the sticker, and the
electric air pump out of the trunk.
Attach the sticker where it will be easily
seen by the driver on the instrument
cluster.
!A wheel change should only be carried out
at an authorized Mercedes-Benz Center. Other-
wise there is a danger of damaging the vehicle by
jacking it up incorrectly.
iOpen door only when conditions are safe to
do so.
Warning!G
Keep TIREFIT away from sparks, open flame
or heat source.
Do not smoke.
Warning!G
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage caused by driving with extremely
low tire inflation pressure, or on a flat tire, or
a damaged wheel.
Do not drive the vehicle under such
circumstances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside
Assistance.
!After using TIREFIT, the tire inflation
pressure sensor may have to be replaced.
