Check tyres Check tyres The tyre pressure loss warning system has detected a significant loss
in pressure.
A warning tone also sounds.
Possible causes:
R you have changed the positions of the wheels and tyres or fitted new
wheels and tyres
R the tyre pressure in one or more tyres has dropped
G WARNING
Underinflated tyres pose the following risks:
R the tyres may burst, especially as the load and vehicle speed
increase
R the tyres may wear excessively and/or unevenly, which may greatly
impair tyre traction
R the driving characteristics, as well as steering and braking, may be
greatly impaired
There is a risk of an accident.
X Stop the vehicle without making any sudden steering or braking
manoeuvres. Pay attention to the traffic conditions as you do so.
X Safeguard the vehicle against rolling away (Y page 157).
X Check the tyres and, if necessary, follow the instructions for a flat
tyre (Y page 306).
X Check the tyre pressures and, if necessary, correct the tyre pres-
sure.

sure is correct (Y page 326). Check Check

removed. If this occurs, note that the value dis-
played for the position where the spare wheel is fitted is not the same as the current tyre pres-
sure of the emergency spare wheel.
Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a pressure
loss in one or more tyres, a warning message is
shown in the multifunction display. The yellow
tyre pressure warning lamp then lights up.
R If the Please correct tyre pressure
Please correct tyre pressure
message appears in the multifunction display,
the tyre pressure in at least one tyre is too
low. The tyre pressure must be corrected
when the opportunity arises.
R If the Check
Check tyre(s)
tyre(s) message appears in the
multifunction display, the tyre pressure in at
least one tyre has dropped significantly. The
tyres must be checked.
R If the Warning tyre defect Warning tyre defect message
appears in the multifunction display, the tyre
pressure in at least one tyre has dropped sud- denly. The tyres must be checked.
Observe the instructions and safety notes in the display messages in the "Tyres" section
(Y page 246).
If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed
for the wrong positions for a short time. After a few minutes of driving, this is rectified and the
tyre pressures are displayed for the correct
positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure monitor will automatically detect the new refer-
ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.
X Use the table on the inside of the fuel filler flap
to ensure that the tyre pressure is set cor-
rectly in all four tyres for the current operating
conditions. Also observe the notes in the section on tyre
pressures (Y page 324).

ignition lock.
