228 OperationWinter driving
Winter drivingBefore the onset of winter, have your vehi-
cle 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 321).
Battery test. Battery capacity drops 
with decreasing ambient temperature. 
A well charged battery helps to ensure 
that the engine can be started even at 
low ambient temperatures.
Tire change. We recommend M+S rat-
ed radial-ply tires on all four wheels for 
the winter season.
Winter tires
Always use winter tires at temperatures 
below 39°F (4°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, EBB and 
4-ETS in winter operation.
For safe handling, ensure that all winter 
tires mounted 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 ve-
hicle, you must place a notice to this effect 
where it will be seen by the driver. Such no-tices are available from your tire dealer or 
from any authorized Mercedes-Benz Light 
Truck Center.
Block heater (Canada only)
The engine is equipped with a block heat-
er.
The electrical cable may be installed at 
your authorized Mercedes-Benz Center.
Warning!
G
Winter tires with a tread depth under 0.16 in 
(4 mm) must be replaced. They are no long-
er 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.
