Notes on the tyre pressure
WARNING Risk of accident due to in-
sufficient or excessive tyre pressure
Insufficient or excessive tyre pressure
pose the following risks:
● The tyres may burst and their service
lives are shortened as a result, espe-
cially as the payload and vehicle
speed increase.
● Driving comfort can be compromised.
● Damage may occur when driving on
rugged road.
● The tyre traction can be impaired.
● The tyres may wear excessively and/
or unevenly.
● The handling and braking perform-
ance can be adversely affected.
● Tyres can overheat and deform.
● Vehicle’s operational range can be
reduced.
► Maintain the tyre pressure at a nor-
mal level.
WARNING Risk of accident due to re-
peated tyre pressure drop
If the tyre pressure drops repeatedly,
the wheel, valve or tyre may be
damaged.
Insufficient tyre pressure can cause the
tyres to burst.
► Inspect the tyre for signs of foreign
objects.
► Check whether the wheel or valve
has a leak.
► If you are unable to rectify the fault,
contact a smart Authorized Service
Partner.
