Mercedes-Benz 2010 GL350 BlueTEC Automobile User Manual


 
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance.
Off-road ABS
With the off-road driving program switched
on, or with the transmission in LOW RANGE
mode, the ABS designed for off-road driving
is activated automatically.
When applying the brakes at speeds below
18 mph (30 km/h), the front wheels are
locked cyclically to shorten the braking
distance (dig-in effect). This will restrict
steering the vehicle.
BAS
G
Observe Safety notes, see page 62.
The Brake Assist System (BAS) operates in
emergency situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
X
Apply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated.
G
Warning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
EBP
G
Observe Safety notes, see page 62.
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
the rear brakes to supply a greater proportion
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 62.
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.
