Tire Inflation Pressure
A table (see fuel filler flap or last
page) lists the tire inflation pressures
specified fo r summer and w inter tires
as well as fo r the varying operating
conditions.
Im portant!
Tire pressure differs by approx.
0.1 bar/1.5 psi per 10° C/18° F of air
tem perature change. Keep this in
mind when checking tire pressure
inside a garage — especially in the
winter.

Example:
Room tem perature = approx.
+ 20° C /+ 6 8 ° F
A m bient tem perature = approx.
0° C / + 32° F
A djusted air pressure = specified air
pressure + 0 .2 bar/3 psi.
Tire pressures listed fo r light loads
are minimum values offering high
driving com fort. Increased inflation
pressures fo r heavy loads produce
favorable handling characteristics
w ith lighter loads and are perfectly
perm issible. The ride of the vehicle,
however, will become som ewhat
harder.
Tire tem perature and pressure in
crease with the vehicle speed. Tire
pressure should therefore only be
corrected on cold tires. C orrect 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.
