fore running it through the automatic car
wash.When taking the vehicle through an auto-
matic conveyor type car wash, observe the
following instructions.

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 400). Otherwise, e.g. 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 dam-
age to the mirrors.
Warning!

Vehicle care
Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.Headlamps, tail lamps, side markers,
turn signal lenses

Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water.Cleaning the DISTRONIC Plus*/

Switch off the ignition (
page 365).

Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water and a
non-scratching cloth to clean sensor
cover1.
i
After running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 603). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may
vibrate.
!
Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which you
are sure are chrome-plated, use a chrome clean-
er. If in doubt whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Center.
!
Only use window cleaning solutions that are
suitable for plastic lamp lenses. Window clean-
ing solutions which are not suitable may damage
the plastic lamp lenses of the headlamps. There-
fore, do not use abrasives, solvents or cleaners
that contain solvents.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry
cloth or sponge.
Otherwise you may scratch or damage the lens
surface.

Possible cause/consequence
Suggested solution
±
The yellow engine malfunc-
tion indicator lamp comes
on while driving.
There is a malfunction in:

The fuel management system


The ignition system


The emission control system


Systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the en-
gine to Limp-Home Mode (emergency oper-
ation).

Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics system.
It allows the accurate identification of
system malfunctions through the read-
out of diagnostic trouble codes. It is lo-
cated in the front left area of the
footwell.
i
Some states may by law require you to visit
a workshop as soon as the engine malfunction
indicator lamp comes on. Check local require-
ments.

On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may ap-
pear in the malfunction display.
For your convenience the messages are di-
vided into two sections:

Text messages (

Symbol messages (
page 639)
Warning!
G
All categories of messages contain impor-
tant information which should be taken note
of and, where a malfunction is indicated, ad-
dressed as soon as possible at an autho-
rized Mercedes-Benz Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property dam-
age or personal injury.i
Switching on the ignition causes all instru-
ment cluster lamps (except high beam headlamp
indicator lamp and turn signal indicator lamps
unless activated) as well as the multifunction dis-
play to come on. Make sure the lamps and multi-
function display are in working order before
starting your journey.

Possible cause/consequence
Possible solution
Front Passenger
Airbag Disabled
See Oper. Manual
Front passenger front air bag is
deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Engage the electronic parking brake (
page 412).

Switch off the ignition (
page 365).

Have the front passenger vacate the seat and exit the vehicle.

Adjust the seat in a height position (
page 368).

Make sure that no objects which apply forces to the seat are present (e.g.
objects such as books, briefcases etc. lodged underneath, behind or
around the seat). Such forces may cause the system to sense that an oc-
cupant of a lesser weight than actually present is on the front passenger
seat.

Keep the seat unoccupied, close the passenger door and switch on the ig-
nition (
page 365).
Monitor the 59indicator lamp right of the instrument cluster
(
page 51) and the multifunction display in the instrument cluster
(page 282) for the following:

Possible cause/consequence
Possible solution
Front Passenger
Airbag Disabled
See Oper. Manual
With the seat unoccupied and the ignition switched on (
page 365),


the 59indicator lamp right of the instrument cluster should
illuminate and remain illuminated, indicating that the OCS (
page 48)
has deactivated the air bag.


the message “Front Passenger Airbag Enabled See Oper. Manual” or the
message “Front Passenger Airbag Disabled See Oper. Manual” should not
appear in the multifunction display at any time the seat is unoccupied.
Wait at least 60 seconds for the system to complete the necessary check
cycles and to make sure neither message appears in the multifunction dis-
play.
If above conditions are met, you can occupy the front passenger seat again.
Depending on the front passenger classification sensed by the OCS
(
page 48), the59indicator lamp will remain illuminated or go
out.
If above conditions are not met, the system is not working properly. Have the
system checked as soon as possible by an authorized Mercedes-Benz Center.
Warning!
G
If the 59indicator lamp re-
mains illuminated with an adult occupant on
the front passenger seat even after
performing the above corrective steps, do
not have any passenger use the front pas-
senger seat until the system has been re-
paired.
