STARTING AND DRIVING
426
Brake Assist System
The brake enhancing system, Brake Assist
System (BAS), helps increase braking force and
thereby reduce braking distance.
The system monitors the driver's braking habits
and increases braking force when necessary.
Braking force can be increased up to the point at
which the ABS intervenes. The function is deacti-
vated when pressure on the brake pedal is
decreased.
NOTE
When BAS is activated, the brake pedal will
go down slightly more than usual. Press
(hold) down the brake pedal as long as nec-
essary.
When the brake pedal is released, all braking
ceases.

Braking on wet roads
Prolonged driving in heavy rain without braking
may cause braking effect to be slightly delayed
the first time the brakes are applied.
This may also occur after washing the vehicle. It
will then be necessary to apply greater pressure
to the brake pedal. You should therefore maintain
a greater distance to the vehicle ahead.
Firmly apply the brakes after washing the vehicle
or driving on wet roads. This helps warm up the
brake discs, enabling them to dry more quickly
and protecting them against corrosion. Consider
the current traffic situation when braking.

Braking on salted roads
When driving on salted roads, a layer of salt may
form on the brake discs and brake pads.
This could increase stopping distance. Maintain
an extra large safety distance to the vehicle
ahead. Make sure to also:
•
Apply the brakes from time to time to help
remove salt. Make sure braking does not
pose a risk to any other road users.
•
Gently apply the brakes when you have fin-
ished driving and before driving again.
