such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or

EBB

The Electronic Brake Booster (EBB)
enhances braking effectiveness by allow-
ing the rear brakes to supply a greater
proportion of the braking effort in straight
line braking circumstances without a loss
of vehicle stability.
Warning!
If the EBB is malfunctioning, the brake
system is still functioning. However, the rear

may
wheels may lock during hard braking, caus-
ing you to lose control over the vehicle and
possibly causing an accident. Adjust your
driving style to the non-operating status of
the EBB.

hints" section ( page 327).

ESP

The Electronic Stability Program (ESP
operational as soon as the engine is run-
ning and monitors the vehicle's traction
(force of adhesive friction between the
tires and the road surface) and handling.
®
The ESP recognizes when a wheel is
spinning or if the vehicle starts to skid.
G
By applying the brakes to the appropriate
wheel and by limiting engine output, the
®
ESP works to stabilize the vehicle.
®
The ESP is especially useful while driving
off and on wet or slippery road surfaces.
®
The ESP also stabilizes the vehicle during
braking and steering maneuvers.
