Tire Pressure Checkup
The proper cold tire inflation pressure
is indicated on the table "Tire Inflation
Pressure" in section "Features and
Specifications".
Inflation pressure specified on the
table always refers to "cold tire
inflation pressure". Cold tire inflation
pressure is defined as the tire pressure
after the vehicle has not been driven
for at least three hours, or driven less
than 1.6 km (1 mi) after a three hour
period.
Check tire pressures more often in
case of significant outside
temperature changes, as tire pressure
varies according to temperature
changes.
The pressure should be checked and if
necessary adjusted; tire wear and
overall conditions should also be
checked monthly. Tire pressures
change by approximately 0.07 bar per
7°C of air temperature change. Keep
this in mind when checking tire
pressure inside a garage, especially in
winter.
Example: If garage temperature =
20°C and the outside temperature =
0°C then the cold tire inflation
pressure should be increased by 0.21
bar for every 7°C for this outside
temperature condition.
Tire pressure may increase from 0.13
to 0.4 bar during operation. DO NOT
reduce this normal pressure build-up
or your tire pressure will be too low.
After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve stem,
which could damage the valve stem
and the TPMS sensor connected to it.
Tread Wear Indicators
Tread wear indicators are in the
original equipment tires to help you
determine when your tires should be
replaced.
These indicators are moulded into the
bottom of the tread grooves. They will
appear as bands when the tread depth
becomes 1,6 mm (0.06 in) or 4 mm
(0.16 in) for winter or all-season tires.
When the tread is worn to one of the
tread wear indicators, the tire should
be replaced.
WARNING!
The wet performance (aquaplaning
resistance) will decrease
proportionally to the thickness of the
tread.
Tires Durability
The service life of a tire depends on
various factors including, but not
limited to:
• driving style;
• tire pressure;
• distance driven.
WARNING!
Tires and the spare tire (if equipped)
should be replaced after six years,
regardless of the remaining tread.
Failure to follow this warning can
result in tire failure. You could lose
control and have a collision resulting
in serious injury or death.
