Mercedes Benz 2009 M-Class User Manual

Because of their narrow profile, the vehi-
cles traveling near the outer edges of the 
lane have not yet been detected by 
Distronic. There will be insufficient 
distance to the vehicles ahead.

When Distronic* is deactivated, this 
function will continue to warn you when 
recognizing a stationary obstacle or a 
slower vehicle moving in your vehicle’s 
path and the danger of a collision exists:

앫

The distance warning lamp

l in the 

instrument cluster comes on.

앫

An intermittent warning will sound if 
necessary.

If these warnings are issued, you must 
brake manually to maintain a safe distance 
and avoid a collision with the preceding 
vehicle.

When pressing the brake pedal, the warn-
ing sound ceases. The warning sound will 
also cease when the distance to the 
preceding vehicle is sufficient again with-
out applying the brakes. In this case, the 
distance warning lamp will also go out.

왘

Switch on the distance warning 
function in the control system 
(

컄

page 179).

G

If the distance warning lamp

l in the in-

strument cluster comes on while driving 

and/or an intermittent warning sounds, 

immediate attention on the part of the driver 

is required. As required by the traffic 

situation, apply the brakes and navigate 

around a possible obstacle. However, do not 

drive by relying on the distance warning 

function, as this will result in an emergency 

braking application. This will not always 

enable you to avoid a collision, especially 

when traveling on varying road surface 

conditions and with varying driver reaction.

Complex driving situations are not always 

fully recognized by the distance warning 

function. This could result in wrong or miss-

ing distance warnings.
