Mercedes Benz 2007 r 320 cdi User Manual

Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal 
force may become necessary to produce 
the normal brake effect.

Depressing the brake pedal periodically 
when traveling at length on salt-strewn 
roads can bring road-salt-impaired braking 
efficiency back to normal.

If the vehicle is parked after being driven 
on salt-treated roads, the braking 
efficiency should be tested as soon as 
possible after driving is resumed.

To prevent water from entering the pas-
senger compartment or the engine com-
partment if you must drive through 
standing water, keep in mind that

앫

the maximum depth of the water may 
not exceed 10 in (25 cm)

you must drive slowly

Make sure not to endanger any other road 

users when carrying out these braking 

maneuvers.

G

If the vehicle becomes stuck in snow, make 

sure that snow is kept clear of the exhaust 

pipe and from around the vehicle with the 

engine running. Otherwise, deadly carbon 

monoxide (CO) gases may enter vehicle 

interior resulting in unconsciousness and 

death.

To assure sufficient fresh air ventilation, 

open a window slightly on the side of the 

vehicle not facing the wind.

G

The outside temperature indicator is not 

designed to serve as an ice-warning device 

and is therefore unsuitable for that purpose. 

Indicated temperatures just above the freez-

ing point do not guarantee that the road sur-

face is free of ice.
