Transmission fluid level
The transmission fluid level does not need

have an authorized Mercedes-Benz Light 
Truck Center check the automatic trans-
mission.
Coolant level
The engine coolant is a mixture of water 
and anticorrosion/antifreeze. To check 
the coolant level, the vehicle must be 
parked on level ground.
!
Excess oil must be siphoned or drained off. 
It could cause damage to the engine or 
emission control system not covered by the

Warning!
G
In order to avoid any possibly serious burns:
Use extreme caution when opening the 
hood if there are any signs of steam or 
coolant leaking from the cooling system, 
or if the coolant temperature gauge indi-
cates that the coolant is overheated.
Do not remove pressure cap on coolant 
reservoir if coolant temperature is 
above 158°F (70°C). Allow engine to 
cool down before removing cap. The 
coolant reservoir contains hot fluid and 
is under pressure.
