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.

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 pressure that is too low may result
in a tyre blow-out. There is a risk of acci-
dent.
Check the tyre for foreign objects.
R
Check whether the wheel is losing air
R
or the valve is leaking.
If you are unable to rectify the damage,
contact a qualified specialist workshop.
H
Environmental note
Check the tyre pressure regularly, at
least every 14 days.
