cluster displayPractical hints Car care Index 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 356.
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 309.
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 346 for location of the spare wheel, and
page 356 for tire inflation pressure.

Engine oil level indicator
To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after turning
off the engine, allowing for the oil to return to the oil
pan.
The message “OBSERVE WAITING PERIOD” will be
displayed if the required waiting period has not been
observed after turning off the engine:
•with engine at operational temperature
approximately 5 minutes.•with engine not at operational temperature up to
approximately 30 minutes.
The engine oil level check can be repeated after a short
time.
Turn the electronic key in starter switch to position 2.
To call up the trip odometer and main odometer, press
button è or ÿ on the multifunction steering
wheel until the display appears. See page 122.
Press button j or k on the multifunction
steering wheel repeatedly until the “CORRECT
MEASUREMENT ONLY IF VEHICLE LEVEL” engine oil
level indicator appears. This indicator is only a
reminder. Measurement can be cancelled by pressing
button j or k if the vehicle is not parked on level
ground. An incorrect reading will be recorded if you do
not cancel the measurement. Move the vehicle to level
ground and measure again.
The electronic key in starter switch is not in position 2 if
the “ENGINE OIL LEVEL – IGNITION ON PLEASE!”
message appears.
The “ENGINE OIL LEVEL – MEASUREMENT IN
PROCESS” message is displayed after approximately
3seconds.

To signal minor directional changes, such as changing
lanes on a highway, move combination switch briefly to
the point of resistance only and release. The turn
signals blink three times.
To operate the turn signals continuously, move the
combination switch past the point of resistance (up or
down). The switch is automatically canceled when the
steering wheel is turned to a large enough degree.
Turn signal failure
If one of the turn signals fails, the turn signal indicator
system flashes and sounds at a faster than normal rate.

Failure to complete either of these steps will result in a
system that is not activated. If the system is not
activated the indicator lamp in the “SOS” button stays
on after turning electronic key in starter switch to
position 2 (vehicles with KEYLESS-GO:
operating position, see page 232) and the message
“TELE AID – NOT ACTIVATED” will be shown in the
