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.
For more information, see the “Practical
hints” section (
컄
page 327).
ESP
®
The Electronic Stability Program (ESP
®
) is
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.
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.
The ESP
®
warning lamp
v
in the instru-
ment cluster (
컄
page 26) flashes when the
ESP
®
is engaged.
The ESP
®
warning lamp
v
comes on
when you switch on ignition (
컄
page 39).
It goes out when the engine is running.
!
Operational or performance test must only
be conducted on a two-axle dynamometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!
Because the ESP
®
operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position
0 or 1 )
when testing the parking brake on a brake test
dynamometer and such testing should be no
longer than 10 seconds.
Active braking action through ESP
®
may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
Warning!
G
If the EBB is malfunctioning, the brake
system is still functioning. However, the rear
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.
