1 One or more tires def late rapidly or tire pressure 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 337.
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 337.
3 For tire inflation pressure monitor, see page 150.4 Tire pressure in one or more tires is low. Check and correct tire
pressure, see page 345.
5 The tire pressure monitor cannot be activated with the engine
running. Turn off the engine and repeat activation, see page 151.
6 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 345.
The tire inflation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 151.
7 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.
8 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.

CHIP-CARD (KEYLESS-GO)
* C = Category, see page 297.1 Check battery of KEYLESS-GO-card, see page 366.
2 The KEYLESS-GO-card cannot be recognized by the running
engine (e.g. strong radio-frequency interference) or the card is not
in the vehicle.
Stop immediately and search for the KEYLESS-GO-card or continue
to operate the vehicle with the electronic key, otherwise the vehicle
cannot be centrally locked or the engine started again after the
engine stops automatically. See page 38.
3 The KEYLESS-GO-card was momentarily not recognized. If
message repeats, place card in a different position or continue to
operate the vehicle with the electronic key, see page 38.
4 A KEYLESS-GO-card left inside the vehicle has been recognized
while locking the vehicle from the outside, see page 38.
5 The message appears for a maximum 60 seconds each time the
driver’s door is opened, as long as no electronic key is in the
starter switch. The message appears regardless of the past
operation method (electronic key or KEYLESS-GO-card), see
page 38. Line 1Line 2C*
