A table (see fuel filler flap) lists the tire inflation 
pressures specified for Mercedes-Benz recommended 
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approx. 1.5 psi (0.1 bar) per 
18°F (10°C) of air temperature change. Keep this in 
mind when checking tire pressure inside a garage - 
especially in the winter.
Example:
If garage temperature = approx. +68°F (+20°C) and 
ambient temperature = approx. +32°F (0°C) then the 
adjusted air pressure = specified air pressure +3psi 
(+0.2 bar).
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 increase with the vehicle 
speed. Tire pressure should therefore only be checked 
and corrected on cold tires. Correct tire pressure in

The spare wheel rim is for temporary use only. Use 
for over a total of 12 000 miles (20 000 km) may 
cause wheel rim failure leading to an accident and 
possible injuries. Vehicles with Sport Package:
The dimensions of the spare wheel are different 
from those of road wheels. As a result, the vehicle 
handling characteristics change when driving with 
a mounted spare wheel.The spare wheel should only be used temporarily, 
and replaced with a regular road wheel as quickly 
as possible.
