Tire and loading terminology
Accessory weight
The combined weight (in excess of those 
standard items which may be replaced) of 
automatic transmission, power steering, 
power brakes, power windows, power 
seats, radio, and heater, to the extent that 
these items are available as 
factory-installed equipment (whether 
installed or not).
Air pressure
The amount of air inside the tire pressing 
outward on each square inch of the tire. 
Air pressure is expressed in pounds per 
square inch (psi), or kilopascal (kPa) or 
bar.
Aspect ratio
Dimensional relationship between tire 
section height and section width 
expressed in percentage.
Warning!
G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and 
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause 
excessive heat build-up and possible tire 
failure.
iFor illustration purposes only. Actual 
data on tires are specific to each vehi-
cle and may vary from data shown in 
above illustration. 

338 OperationWinter drivingBlock heater* (Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at 
your authorized Mercedes-Benz Center.Snow chains
Snow chains should only be driven on 
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains 
as soon as possible when driving on roads 
without snow.Please observe the following guidelines 
when using snow chains:
Use of snow chains is not permissible 
with all wheel/tire combinations.
Snow chains should only be used on 
the rear wheels. Follow the manufac-
turer's mounting instructions.
Only use snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Center will be 
glad to advise you on this subject.
Use of snow chains may be prohibited 
depending on location. Always check 
local and state laws before installing 
snow chains.
!When driving with snow chains, always 
select the raised level of the level con-
trol system Airmatic* (
page 245). 
Other settings may result in damage to 
your vehicle.
iWhen driving with snow chains, you 
may wish to deactivate the ESP 
(page 91) before setting the vehicle 
in motion. This will improve the vehi-
cle’s traction.
!Even on vehicles with all-wheel-drive 
use snow chains on rear tires only.
Use of snow chains is not permissible 
with tire sizes:
