Driving
Occasionally, but not always, the braking distance is shorter with ABS
control. Ignoring these matters can lead to very dangerous situations
not only for the driver but also for other road users.
– Do not adapt the driving style to the knowledge of having ABS
control.
– Do not brake later and harder. This only causes unnecessary tyre
wear. It may also be extra hazardous for other road users.
Brake assist
Brake assist operates in emergency situations. If the brake pedal is rapidly depressed,
the EBS system will increase the brake pressure to a higher level.
Brake performance monitoring
During braking, the EBS system checks the brake performance of the vehicle or vehicle
combination.
If the vehicle or vehicle combination does not have the normal brake
performance, the 'Low brake performance' warning is shown on the
main display.
Reduced brake performance can be caused by defective brakes, for example worn-out
disk brakes or overheated drum brakes. It can also be caused by severe overloads of
the vehicle or vehicle combination.
The warning remains active until the EBS system has determined that the normal brake
performance has returned.
When the 'Low brake performance' warning is active, you may not be able to brake as
hard as you might otherwise expect. Adapt the driving style and drive cautiously. Brake
using the engine brake and/or the retarder as much as possible. If the message cannot
be logically explained from the loading situation or earlier braking behaviour, get the
brake system checked as soon as possible.
Third brake integration
If the vehicle is fitted with a retarder or engine brake, third brake integration is
automatically available in the EBS system. The EBS system can use braking torque
support from the retarder or engine brake when the service brake is applied. This has
a positive effect on the service life of the brake linings.
Hill Start Aid
If the vehicle is equipped with an automated gearbox, it also has Hill Start Aid. Hill Start
Aid can be used when driving off on a hill, without having to use the park brake. See
section 'Hill Start Aid'.
7.16 ENGINE BRAKE
The engine brake can be an exhaust brake or an MX Engine Brake.
