Wheels and tyres
Tyre pressure
Recommended tyre pressure
The tyre pressure decal 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.
Stated on the decal:
• Tyre pressure for the car’s recommended
wheel size
• ECO pressure
• Spare wheel pressure (Temporary Spare).
Checking the tyre pressure
Check the tyre pressure regularly.
NOTE!
Tyre pressure decreases over time,
this is a natural phenomenon. Tyre pressure
also varies depending on ambient temper-
ature.
The correct tyre pressure is specified in the
tyre pressure table. The specified tyre
pressures refer to "cold tyres". ("Cold tyres"
means the tyres are the same temperature as
the ambient temperature.)
Even after several few kilometres of driving
the tyres warm up and the pressure
increases, so air must not be released if the
pressure is checked when the tyres are
warm, while the pressure must be increased
if it is too low. Inadequately inflated tyres
adversely affect fuel consumption, tyre
lifespan and the car’s roadholding. Driving on
tyres with tyre pressure that is too low can
also result in the tyres overheating and disin-
tegrating. For information on the correct tyre
pressure, refer to the tyre pressure table on
page 156.
Fuel economy, ECO pressure
At speeds under 160 km/h, the general tyre
pressure for full load is recommended in
order to obtain optimum fuel economy.
Tyre pressure affects travelling comfort, road
noise and steering characteristics.
