of the braking effort in straight-line braking
without a loss of vehicle stability.
G Warning!
If the EBP malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.
ESP ®
G Observe Safety notes, see page 60.
The Electronic Stability Program (ESP ® ) is
operational as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP
® recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels and by limiting the 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 d in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
The ESP
® warning lamp d in the
instrument cluster flashes when the ESP ® is
engaged.
G Warning!
Never switch off the ESP ® when you see the
ESP ® warning lamp d flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESP
® cannot
prevent accidents resulting from excessive
speed.
! Vehicles with 4MATIC:
Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz 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 or KEYLESS-GO start/stop
button in position 0 or 1) when
R
the parking brake is being tested on a
brake test dynamometer
R
towing the vehicle with the front or rear
axle raised (not permissible for vehicles
with 4MATIC)
Active braking action through the ESP ®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! The ESP ® will only function properly if you
use wheels of the recommended tire size
