The GVW comprises the weight of the 
vehicle including fuel, tools, spare wheel, 
installed accessories, passengers and 
cargo and, if applicable, trailer tongue 
load. The GWV must never exceed the 
GWVR indicated on the Certification label 
located on the driver’s door B-pillar.

This is the maximum permissible vehicle 
weight of the fully loaded vehicle (weight of 
the vehicle including all options, passen-
gers, fuel, and cargo and, if applicable, 
trailer tongue load). It is indicated on 
Certification label located on the driver’s 
door B-pillar.
Kilopascal (kPa)
The metric unit for air pressure. There are 
6.9 kPa to one psi; another metric unit for 
air pressure is bars. There are 
100 kilopascals (kPa) to one bar.Maximum load rating
The maximum load in kilograms and 
pounds that can be carried by the tire.
Maximum loaded vehicle weight
The sum of curb weight, accessory weight, 
vehicle capacity weight and production 
options weight.
Maximum tire inflation pressure
This number is the greatest amount of air 
pressure that should ever be put in the tire 
under normal driving conditions.
Normal occupant weight
The number of occupants the vehicle is 
designed to seat, multiplied by 
68 kilograms (150 lbs).
Occupant distribution
The distribution of occupants in a vehicle 
at their designated seating positions.Production options weight
The combined weight of those installed 
regular production options weighing over 
5 lbs (2.3 kilograms) in excess of those 
standard items which they replace, not 
previously considered in curb weight or 
accessory weight, including heavy duty 
brakes, ride levelers, heavy duty battery, 
and special trim.
PSI (P
ounds per s
quare i
nch)
A standard unit of measure for air pressure 
-> bar, kilopascal (kPa).
Recommended tire inflation pressure
Recommended tire inflation pressure 
listed on placard located on driver’s door 
B-pillar for normal driving conditions. 
Provides best handling, tread life and 
riding comfort.

275 Operation
Winter driving
Winter driving
Before the onset of winter, have your 
vehicle winterized at an authorized 
Mercedes-Benz Light Truck Center. This 
service includes:
Check of anticorrosion and antifreeze 
concentration.
Addition of cleaning concentrate to the 
water of the windshield and headlamp 
cleaning system. Add MB Concentrate 
“S” to a premixed windshield washer 
solvent/antifreeze which is formulated 
for below freezing temperatures 
(page 380).
Battery test. Battery capacity drops 
with decreasing ambient temperature. 
A well charged battery helps to make 
sure that the engine can be started, 
even at low ambient temperatures.
Tire change. Mercedes-Benz recom-
mends M+S rated radial-ply tires with a 
minimum tread depth of approximately 1/6in (4 mm) on all four wheels for the 
winter season.
Winter tires
Always use winter tires at temperatures 
below 45°F (7°C) and whenever wintry 
road conditions prevail. Use of winter tires 
is the only way to achieve the maximum ef-
fectiveness of the ABS, ESP, 4-ETS, and 
EBP in winter operation.
For safe handling, make sure that all 
mounted winter tires are of the same make 
and have the same tread design.Always observe the speed rating of the 
winter tires installed on your vehicle. If the 
maximum speed for which your tires are 
rated is below the speed rating of your 
vehicle, you must place a notice to this 
effect where it will be seen by the driver. 
Such notices are available from your tire 
dealer or from any authorized 
Mercedes-Benz Light Truck Center.Warning!
G
Winter tires with a tread depth under 
1/6in 
(4 mm) must be replaced. They are no 
longer suitable for winter operation.
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 Light Truck Center.
