directly related to the operating conditions of the
vehicle.
The symbol9 or½ appears together with a
message in the multifunction indicator prior to the next
suggested service. Depending on operating conditions
throughout the year, the next service is calculated and

One of the following messages will appear in the display
(e.g. Service A):
“SERVICE A – IN xx DAYS”
“SERVICE A – IN xx MILES” (Canada: KM)
“SERVICE A – EXCEEDED BY xx DAYS”
“SERVICE A – EXCEEDED BY xx MILES” (Canada: KM)
“SERVICE A – PERFORM SERVICE”
The next service due date is displayed either in days or

(optional for Canada)
The tire inflation pressure, as selected by the driver, is
monitored in all four wheels on the ground. A warning
is issued to the driver in the case of a decrease in the
inflation pressure in one or more of the tires.Inquiry of present tire inflation pressure
Turn electronic key in starter switch to position 1 or 2.
Pressè or ÿbutton on the multifunction
steering wheel until the display for trip and main
odometer appears, see page 124.
Press thej or kbutton repeatedly until the tire
inflation pressure monitor is displayed.
The present tire inflation pressure for each wheel is
displayed in multifunction display.
Wa r n i n g !
The tire inflation pressure monitor does not
indicate a warning for wrongly selected inflation
pressures. Always adjust tire inflation pressure
according to the label affixed on the fuel filler flap.
See page 351 for tire inflation pressure.The tire inflation pressure monitor is not able to
issue a warning due to a sudden loss of pressure
(e.g. tire puncture caused by a foreign object). In
this case bring vehicle to a halt by carefully
applying the service brakes and avoiding abrupt
steering maneuvers.

Notes:
To ensure proper functioning of the tire inflation
pressure monitor, the tire inflation pressure should be
checked and corrected according to the label affixed
inside the fuel filler flap. For a detailed description,
refer to page 351.
The message “REACTIVATE – TIRE PRESS. MONITOR”
appears if the tire inflation pressure shows an increase
of 4.4 psi (0.3 bar) or more. Reactivate the tire inflation
pressure monitor.
The tire inflation pressure monitor only functions on
wheels equipped with the proper electronic sensors.
Inquire at your authorized Mercedes-Benz Center about
retrofitting other than original Mercedes-Benz wheels
with electronic sensors.
Transporting a deflated road wheel in the vehicle, e.g.
after having a flat, the tire inflation pressure monitor
should only be activated once the flat tire and rim are
removed from the vehicle.To prevent possible damage to the electronic sensors,
have tire changes only performed at an authorized
Mercedes-Benz Center.
For malfunction and warning messages, see page 318.
When checking the tire inflation pressure of the road
wheels, also check the spare tire.
The tire inflation pressure of the spare wheel, mounted
or not mounted, is not monitored by the tire inflation
pressure monitor.
See page 341 for location of the spare wheel, and
page 351 for tire inflation pressure.

“ENGINE OIL LEVEL – O.K.”
No oil needs to be added.
“ENGINE OIL LEVEL – ADD 1.0 QUART”
(Canada: 1.0 L)
“ENGINE OIL LEVEL – ADD 1.5 QUART”
(Canada: 1.5 L)
“ENGINE OIL LEVEL – ADD 2.0 QUART”
(Canada: 2.0 L)
See “Checking engine oil level”, on page 337 for
instructions on adding engine oil.
“ENGINE OIL LEVEL – REDUCE OIL LEVEL”
Do not overfill the engine.
Excessive oil must be siphoned or drained off. It could
cause damage to the engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
The “MEASURING NOT POSSIBLE!” message will be
displayed if a proper oil level check cannot be
performed. The engine oil level check can be repeated
after a short while.CL 500 and CL 55 AMG only:
Perform the engine oil level check with the dipstick, if it
cannot be completed via the multifunction display.
See “Checking engine oil level”, page 337.
In this case we recommend that you have the system
checked at a Mercedes-Benz Center.
Notes:
See malfunction and warning messages on page 303
and page 320 if an engine oil level indicator appears on
the multifunction display when the engine is running.
The engine oil level cannot be checked while the engine
is running. The “ENGINE OIL LEVEL – NOT WHEN
ENGINE ON” message will appear.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.
