1 One or more tires is or has deflated rapidly. Carefully bring the
vehicle to a halt, avoiding abrupt steering and braking maneuvers.
For reference on changing wheels, see page 348.
2 The tire pressure on one or more tires is already below minimum
value. Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. For reference on changing
wheels, see page 351.
3 For tire inflation pressure monitor, see page 152.4 Tire pressure in one or more tires is low. Check and correct tire
pressure according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 356.
The tire inf lation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 152.
5 When the message appears after starting the engine, the tire
inflation pressure on all road wheels should be checked and
corrected according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 356.
The tire inf lation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 152.
6 The tire inflation pressure monitor system is unable to monitor the
tire pressure due to the presence of several wheel electronics in
the vehicle (e.g. a deflated road wheel in the trunk), or nearby
radio interference source, or excessive wheel sensor temperatures,
or unrecognized wheel sensors mounted.
7 The tire inflation pressure monitor is defective or a wheel without
proper sensor was installed. Visit your authorized Mercedes-Benz
Center.Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire will cause excessive heat build-up and possibly
a fire.

* C = Category, see page 309.
1 The engine oil level must be checked immediately. See Engine oil
level indicator on page 156.
2 There is no oil in the engine. There is a danger of engine damage.3 There is a risk of damaging the engine or catalytic converter. The
engine oil level must be checked immediately. See Engine oil level
indicator on page 156.
4 The engine oil level has dropped to a critical level.
Check the engine oil level immediately. See Engine oil level
indicator on page 156 and check the engine for visible leakage
(loss of oil).
Possibility of water in the engine oil. Have the engine oil checked.
5 The measuring system is malfunctioning.
When the “ENGINE OIL LEVEL – CHECK LEVEL!”
message appears while the engine is running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning will first come on
intermittently and then stay on if the oil level drops
further.
If no oil leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The engine oil level warnings should not be ignored.
Extended driving with the symbol displayed could
result in serious engine damage that is not covered by
the Mercedes-Benz Limited Warranty.
