Spare tyre pressure (Temporary Spare).
Check the tyre pressure on cold tyres. "Cold
tyres" means the tyres are the same tempera-
ture as the ambient temperature. After several
few kilometres of driving, the tyres warm up
and the pressure increases.
Inadequate tyre pressure increases fuel con-
sumption, shortens tyre lifespan and impairs
the car's driving characteristics. Driving on
tyres with tyre pressure that is too low could
result in the tyres overheating and being
damaged. Tyre pressure affects travelling
comfort, road noise and driving characteris-
tics.
The tyre pressure label on the driver's side
door pillar (between frame and rear door)
shows which pressures the tyres should have
at different loads and speed conditions. This
is also specified in the tyre pressure table,
see Tyres - approved tyre pressures (p. 420).
NOTE
Fuel economy, ECO pressure
Tyre pressure decreases over time, this is
a natural phenomenon. Tyre pressure also
varies depending on ambient temperature.
In order to obtain optimum fuel economy at
speeds below 160 km/h (100 mph) an ECO
pressure is recommended (applies to both full
and light load), see Tyres - approved tyre
pressures (p. 420).
