Mercedes Benz 2007 r 320 cdi User Manual

During severe operating conditions and 
stop-and-go city traffic, the coolant 
temperature may rise to approximately 
248°F (120°C).

The engine should not be operated 
with the coolant temperature above 
248°F (120°C). Doing so may cause seri-
ous engine damage which is not covered 
by the Mercedes-Benz Limited Warranty.

G

Inhalation of exhaust gas is hazardous to 

your health. All exhaust gas contains carbon 

monoxide (CO), and inhaling it can cause un-

consciousness and possible death.

Do not run the engine in confined areas 

(such as a garage) which are not properly 

ventilated. If you think that exhaust gas 

fumes are entering the vehicle while driving, 

have the cause determined and corrected 

immediately. If you must drive under these 

conditions, drive only with at least one win-

dow fully open at all times.

앫

Driving when your engine is overheated 
can cause some fluids which may have 
leaked into the engine compartment to 
catch fire. You could be seriously 
burned.

앫

Steam from an overheated engine can 
cause serious burns and can occur just 
by opening the engine hood. Stay away 
from the engine if you see or hear steam 
coming from it.

Turn off the engine, get out of the vehicle 

and do not stand near the vehicle until the 

engine has cooled down.
