Citroen 7550 Model Vehicle User Manual


 
Driving
As soon as the wear of the front brake pads becomes appreciable so that
replacement is necessary the yellow warning light G in the dial 3 comes on.
Should these warnings appear while on the road it is vital that you should have
the braking system inspected by the nearest CITROEN Agent, driving with extra
care to reach him.
When switching on for starting the red warning light B comes on: this is quite
normal. Wait for it to go out before setting off.
You are reminded that the efficient operation of the engine or of the brakes
precludes fitting anything:
either in the air duct to the engine
or in front of the cooling ducts for the brakes.
STOPPING DISTANCE
The soft suspension of the DS and its general comfort coupled with the monotony
of motorway driving or a long journey tend to make the driver unaware of speed.
Added to this the top speed of the DS has been raised year after year.
Bear in mind that the rate of deceleration produced by the most efficient brakes is
ultimately limited by the adhesion between the tyres and the road surface.
Moreover the distance travelled by the car during braking at a given deceleration,
however effective the braking effort, increases considerably with speed. At 25
mph (40 km/h), for instance, this distance is about 33 ft (10 metres) whereas it
becomes 524 ft (160 metres) (i.e. 16 times longer) by just raising the speed by a
factor of four, i.e. to 100 mph (160 km/h).
The total stopping distance is made up of the distance travelled with the brakes
applied and that covered between the instant the obstacle appears and that when
