Emergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) or air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 297) for
instructions on initiating an emergency call
manually.
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
Connecting Call
appears in the multifunction display and
the audio system is muted. When the
connection is established, the message
Call Connected appears in the multifunc-
tion display. All information relevant to the
emergency, such as the location of the
vehicle (determined by the GPS satellite
location system), vehicle model, identifica-
tion number and color are generated.A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to
determine more precisely the nature of the
emergency provided they can speak to an
occupant of the vehicle.
The Tele Aid system is available if:
it has been activated and is
operational. Activation requires a
subscription for monitoring services,
connection and cellular air time
the relevant cellular phone network
and GPS signals are available and pass
the information on to the Response
Center
Warning!G
If the indicator lamps in the SOS button, in
the Roadside Assistance button and/or in
the Information button remain illuminated
constantly in red and/or message
Tele Aid Inoperative is displayed in the
multifunction display after the system
self-check, a malfunction in the system has
been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
iLocation of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.

Vehicle care
Chrome-plated exhaust tip*
Regular cleaning and care of chrome-plat-
ed exhaust tips will help to maintain their
shine and the classy appearance.
Use Mercedes-Benz approved Chrome
Polishing Paste each time the vehicle
has been washed, especially during the
winter.Light alloy wheels
If possible, clean wheels once a week.
Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light
alloy wheels.Plastic and rubber parts
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Wipe with a cloth moistened in a
lukewarm solution.
The surface may temporarily change
color. If this is the case, wait for it to
dry.
!Do not use alkaline cleaners such as wheel
cleaners as they could cause corrosion.
!Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!The vehicle should not be parked for an
extended period of time immediately after it has
been cleaned, especially not after the wheel rims
have been cleaned with wheel rim cleaner.
Wheel rim cleaners can lead to increased
corrosion of the brake disks and brake pads.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning. Therefore, the vehicle’s brake system
should always be warmed-up before it is parked
after cleaning. To do so, please drive your vehicle
for several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved Tire
Care and Mercedes-Benz approved Wheel Care
products, take care not to spray them on the
brake disks.
Warning!G
Do not use cleaners or cockpit care sprays
containing solvents to clean the cockpit or
the steering wheel. Cleaners containing sol-
vents will make the surface porous and vehi-
cle occupants could suffer serious injuries
from plastic parts coming loose in the event
of air bag deployment.

Upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently
discolored. By lining the seats with a
proper intermediate cover,
contact-discoloration will be prevented.Leather upholstery
Please note that leather upholstery is a
natural product and is therefore subject to
a natural aging process. Leather
upholstery may also react to certain
ambient influences such as high humidity
or high temperature by showing wrinkles
for example.
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather
Care.
Exercise particular care when cleaning
perforated leather as its underside should
not become wet.Wood trims
Dampen cloth using water and use
damp cloth to clean wood trims in your
vehicle.
Warning!G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent
deployment of the head-thorax air bags
(CLK cabriolet)
activation of the active head restraints
Contact an authorized Mercedes-Benz
Center for availability.
!Wipe with light pressure to avoid damage to
the upholstery.
!Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as these
may be abrasive.

Front Passenger
Airbag Enabled
See Operator’s ManualFront passenger front air bag is
activated while driving even though
a child, small individual, or object
below the system’s weight
threshold is on the front passenger
seat, or the front passenger seat is
empty. Objects on the seat or
forces acting on the seat may
make the system sense supple-
mental weight.Stop the vehicle in a safe location as soon as possible and check the
front passenger seat for the following:
Switch off the ignition (page 38).
Remove child and child restraint from front passenger seat and
properly secure the child in rear seat employing the child restraint
if necessary.
Make sure no objects applying supplemental weight onto the seat
are present. The system may recognize such supplemental weight
and sense that an occupant on the front passenger seat is of a
greater weight than actually present.
Keep the seat unoccupied, close the front passenger door and
switch on the ignition (
page 38).
