14. Lower car, remove jack.
15. Engage jack tube cover hooks on
top and snap bottom into place.
16. Tighten the five bolts evenly, al­
ways skipping one, until all bolts
are tight.
Observe a tightening torque of
110 Nm (80 Ib-ft).
17. Correct tire pressure.
Important!
Retighten wheel mounting bolts after
approx. 800 km (500 miles). Observe a
tightening torque of 110 Nm (80 Ib-ft).

Tire Inflation Pressure
A table (see fuel filler flap or last page)
lists the tire inflation pressures speci­
fied for summer and winter tires as well
as for the varying operating conditions.
Important!
Tire pressure differs by approx.
0.1 bar (1.5 psi) per 10 °C (18 °F) of air
temperature change. Keep this in mind
when checking tire pressure inside a
garage - especially in the winter.
Example:
If garage temperature =
approx.+ 20 ° C ( + 68 °F)
and, ambient temperature =
approx. 0°C (+ 32 °F)
then the adjusted air pressure =
specified air pressure
+ 0.2 bar (+ 3 psi).
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 cor­
rected on cold tires. Correct tire pres­
sure in warm tires only if pressure has
dropped below the pressure listed in
the table and the respective operating
conditions are taken into consideration
