and after the monitor has learned the correct
tyre pressure for the current operating sit-
uation. This occurs automatically in most
situations, but may also be specified after
restarting the tyre pressure monitor. Before
restarting, check the tyres for the recom-
mended tyre pressure.
The tyre pressure monitor does not provide a
warning in the following cases:
Even loss of pressure on multiple tyres
R
Sudden loss of tyre pressure, e.g. due to
R
penetration by a foreign body
Incorrectly set tyre pressure
R
The tyre pressure monitor has a yellow
warning lamp in the instrument cluster for
indicating a pressure loss or malfunction.
Restarting the tyre pressure monitor
(on-board computer with a mono-
chrome display)
X
Set the tyre pressure of all tyres to the
recommended value.

On the multifunction lever press the ´
button repeatedly until the ° and h
symbols are displayed in the instrument
cluster display.
X
Press and hold the a button on the mul-
tifunction lever.
The ° and h symbols flash in the
instrument cluster display for approx-
imately five seconds. The two symbols
then light up.
The tyre pressure monitor is restarted.

WARNING
Underinflated or overinflated tyres pose
the following risks:
the tyres may burst, especially as the
R
load and vehicle speed increase.
the tyres may wear excessively and/or
R
unevenly, which may greatly impair
tyre traction.
the driving characteristics, as well as
R
steering and braking, may be greatly
impaired.
There is a risk of an accident.
Observe the recommended tyre pressure
and check the tyre pressure of all the tyres:
at least every two weeks
R
when the load changes
R
before embarking on a longer journey
R
for changed operating conditions, e.g.
R
off-road driving
If necessary, correct the tyre pressure.
G
WARNING
If you mount unsuitable accessories onto
tyre valves, the tyre valves may be over-
loaded and malfunction, which can cause
tyre pressure loss. Aftermarket tyre pres-
sure monitoring systems will cause the
tyre valve to remain open. This can also
result in tyre pressure loss. There is a risk
of an accident.
Only screw standard valve caps or valve
caps specifically approved by smart for
your vehicle onto the tyre valve.
G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
