10. Lower car and remove jack.
Tighten the five bolts evenly by
going around the wheel and
tightening every other bolt until
all the bolts are tight. Observe a
tightening torque of 10 m kp/
72 Ib-ft.
11. Correct tire pressure.
Tire Inflation Pressure
A table (see fuel filler flap or last
page) lists the tire inflation pressures
specified for summer and winter tires
as well as for the varying operating
conditions.
Tire pressures listed for light loads
are minimum values offering high
driving comfort. Increased inflation
pressures for heavy loads produce
favorable handling characteristics
with lighter loads and are perfectly
permissible. The ride of the vehicle,
however, will become somewhat
harder.
Tire temperature and pressure in­
crease with the vehicle speed. Tire
pressure should therefore only be
corrected on cold tires. Correct tire
pressure in hot tires only if pressure
has dropped below the data listed in
the table and the respective operating
conditions are taken into considera­
tion.
