Checking the wheel clearance
*
NOTE Damage to the steering linkage
due to snow chains
If the clearance between the snow chain and
steering linkage is less than 25 mm, the snow
chain could damage the steering linkage.
#
In this case, remove the snow chains
again.
#
Have the steering geometry checked at
a qualified specialist workshop.
#
Apply the parking brake.
#
Fit the snow chains in accordance with the
fitting instructions of the chain manufacturer.
#
Start the engine.
#
Turn the steering wheel towards the co-driver
side to the stop.
With the steering on full lock, there must be a
clearance of at least 30 mm between the
snow chain and the drag link.
Cold climate package
Cold-start limits
Without special equipment, your vehicle is capa‐
ble of starting at temperatures as low as -20 °C.
When fitted with the special equipment and filled
with cold-resistant operating fluids, your vehicle
can be started at temperatures as low as -30 °C.
%
At temperatures lower than the stated cold-
start limits, engine starting may be impaired
despite taking the appropriate measures.

Hydraulic fluid (345.0): the use of the hydraulic
fluid is not permitted in vehicles with a steered
leading/trailing axle. A list of approved operating
fluids can be found in the Mercedes-Benz Specifi‐
cations for Operating Fluids.
Have the vehicle converted to cold-resistant oper‐
ating fluids at a qualified specialist workshop.
Remember to fill the vehicle fuel tank with winter
diesel fuel when it is time to do so.
%
If the vehicle is mainly operated at low tem‐
peratures, the maintenance intervals are
reduced.
Function of the coolant preheater
The coolant preheater consists of an electrical
heating element and is installed in the engine
crankcase. The coolant preheater is operated
independently of the on-board electrical system
with a voltage of 230 V.
