Tires and wheels
Certification label
Even after careful determination of the 
combined weight of all occupants, cargo 
and the trailer tongue load (if applicable) 
(
page 557) as to not exceed the permis-
sible load limit, you must make sure that 
your vehicle never exceeds the Gross Vehi-
cle Weight Rating (GVWR) and the Gross 
Axle Weight Rating (GAWR) for either the 
front or rear axle. You can obtain the 
GVWR and GAWR from the certification la-
bel. The certification label can be found on 
the driver’s door B-pillar, see “Technical 
data” (
page 712).Gross Vehicle Weight Rating (GVWR): The 
total weight of the vehicle, all occupants, 
all cargo, and the trailer tongue load 
(
page 557) must never exceed the 
GVWR.
Gross Axle Weight Rating (GAWR): The to-
tal allowable weight that can be carried by 
a single axle (front or rear). 
To assure that your vehicle does not ex-
ceed the maximum permissible weight 
limits (GVWR and GAWR for front and rear 
axle), have the loaded vehicle (including 
driver, passengers and all cargo and, if ap-
plicable, trailer fully loaded) weighed on a 
suitable commercial scale.Trailer tongue load
The tongue load of any trailer is an impor-
tant weight to measure because it affects 
the load you can carry in your vehicle. If a 
trailer is towed, the tongue load must be 
added to the weight of all occupants riding 
and any cargo you are carrying in the 
vehicle. The tongue load typically is 10% of 
the trailer weight and everything loaded in 
it.
Your Mercedes-Benz has been designed 
primarily to carry passengers and their 
cargo. Mercedes-Benz does not recom-
mend trailer towing with your vehicle.

581 Operation
Winter driving
Snow chainsSnow chains should only be driven on 
snow-covered roads at speeds not to 
exceed 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 
(
page 718).
Use snow chains in pairs and on rear 
wheels only. Follow the manufacturer’s 
mounting instructions.
Only use snow chains that are 
approved by Mercedes-Benz. Any 
authorized 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.
Do not use snow chains on the spare 
wheel (
page 718).
Warning!G
If you use your spare tire when winter tires 
are fitted on the other wheels, be aware that 
the difference in tire characteristics may 
very well impair turning stability and that 
overall driving stability may be reduced. 
Adapt your driving style accordingly.
Have the spare tire replaced with a winter 
tire at the nearest authorized 
Mercedes-Benz Center.
!When driving with snow chains, always se-
lect the raised level of the level control system 
Airmatic (
page 440) or ABC* (page 443). 
Other settings may result in damage to your 
vehicle.
! Even on vehicles with all-wheel-drive, use 
snow chains on rear tires only.
 Some tire sizes do not leave adequate clearance 
for snow chains. To help avoid serious damage to 
your vehicle or tires, make sure that the use of 
snow chains is permissible as specified in the 
“Technical data” section of this Operator’s 
Manual, see “Rims and tires” (
page 718).
! If snow chains are mounted to the front 
wheels, they may scrape against the body or axle 
components. The tires or the vehicle could be 
damaged as a result.
iAll models except S 63 AMG:
When driving with snow chains, you may wish to 
switch off the ESP
® (page 73) before setting 
the vehicle in motion. This will improve the 
vehicle’s traction.
iS 63 AMG:
Do not switch off the ESP® when driving in snow 
or with snow chains mounted.
