2008 MERCEDES-BENZ CL-Class air condition

622 Practical hintsWhat to do if …?Vehicle status messages in the multi-function display
Warning and malfunction messages ap-
pear in the multifunction display located in
the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
High-priority messages are shown in red
on the multifunction display. Messages of
lower priority are also shown in yellow or
white.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.Certain messages of high priority cannot
be cleared from the multifunction display
using# or L on the multifunction
steering wheel (
page 283).
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using# or L. They are then stored
in the vehicle status message memory
(
page 300). Remember that clearing a
message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.
Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Contact an authorized
Mercedes-Benz Center as soon as possible.

What to do if …?
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 (

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.

Display
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.

736 Technical dataFuels, coolants, lubricants, etc.Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System. For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet (USA
only), or contact an authorized
Mercedes-Benz Center.
Engine oil additivesAir conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Any au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!
Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or chang-
ing of oil and oil filter at change intervals longer
than those called for by the Maintenance System
will result in engine or emission control system
damage not covered by the Mercedes-Benz Lim-
ited Warranty.
Please follow Maintenance System recommen-
dations for scheduled oil changes. Failure to do
so will result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz
Limited Warranty.
!
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from blending
oil additives are not covered by the
Mercedes-Benz Limited Warranty.
!
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the system
will occur.
Warning!
G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere.
Under extremely strenuous operating condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement inter-
val.
