2010 MERCEDES-BENZ GL Owners 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
GObserve 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.
XApply 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.
GWarning!
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
GObserve 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.GWarning!
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 ®
GObserve 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.
Driving safety systems63Safety and securityX164_AKB; 5; 31, en-USd2ureepe,Version: 2.11.8.12009-09-11T12:30:16+02:00 - Seite 63Z

GWarning!
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.
! 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 the parking
brake is being tested on a brake test
dynamometer. Such testing should be no
longer than 10 seconds.
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
as specified in the “Technical data” section
of this Operator’s Manual.
i The Distronic system and cruise control
switch off automatically when the ESP ®
engages.
Electronic Traction System (4-ETS) GObserve Safety notes, see page 62.
The 4-ETS (four-wheel Electronic Traction
System) is a component of the ESP ®
. The
4-ETS improves the vehicle’s ability to utilize
available traction, especially under slippery
road conditions by applying the brakes to a
spinning wheel. In addition, more power is
transferred to the wheel(s) with traction.
When you switch off the ESP ®
, the 4-ETS is
still enabled.
XIf conditions require, switch on the off-road
driving program ( Y page 158) or the LOW
RANGE mode ( Y page 119).
Off-road 4-ETS
With the off-road driving program switched on
( Y page 158), or the transmission in LOW
RANGE mode ( Y page 120), the 4-ETS
designed for off-road use is activated
automatically.
Switching off the ESP ®
GWarning!
The ESP
®
should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP ®
when a spare
wheel is mounted.
To improve the vehicle’s traction, switch off
the ESP ®
. This allows the drive wheels to spin
and thus cut into surfaces for better grip, for
example
R when driving with snow chains
R in deep snow
R in sand or gravel

GWarning!
Switch on the ESP® immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the ESP® will not
stabilize the vehicle when it is starting to skid
or a wheel is spinning.
When you switch off the ESP®,
Rthe ESP® does not stabilize the vehicle
Rthe engine output is not limited, which
allows the drive wheels to spin and thus cut
into surfaces for better grip
Rthe 4-ETS will still apply the brakes to a
spinning wheel
Rthe ESP® continues to operate when you
are braking
Rthe cruise control or the Distronic system
cannot be activated
Rthe cruise control or the Distronic system
switch off if activated
iWhen the ESP® is switched off and one or
more drive wheels are spinning, the ESP®
warning lamp d in the instrument
cluster flashes. However, the ESP® will
then not stabilize the vehicle.
XWith the engine running, press ESP®
switch : until the ESP® warning lamp
d in the instrument cluster comes on.
The ESP® is switched off.
GWarning!
When the ESP® warning lamp d is
illuminated continuously, the ESP® is
switched off or is not operational due to a
malfunction. Vehicle stability in standard
driving maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESP®.
! Avoid spinning of a drive wheel for an
extended period with the ESP® switched
off. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
Switching on the ESP®
XPress ESP® switch : until the ESP®
warning lamp d in the instrument
cluster goes out.
You are now again in normal driving mode
with the ESP® switched on.
Off-road ESP®
With the off-road driving program switched on
(Y page 158), or with the transmission in
LOW RANGE mode (Y page 120), the ESP®
designed for off-road use is activated
automatically. At speeds below 27 mph
(45 km/h), the ESP® assists in over–
understeering, thus improving vehicle
traction.
ESP® trailer stabilization
If the trailer you are towing should begin to
sway, the rig can only be stabilized by
immediately applying the brakes hard.
Steering during this maneuver will not help to
stabilize the rig.
The ESP® will assist you in such situations.
The ESP® recognizes when the trailer starts
swaying and will apply the brakes to reduce
the vehicle speed to a non-critical speed that
Driving safety systems65Safety and securityX164_AKB; 5; 31, en-USd2ureepe,Version: 2.11.8.12009-09-11T12:30:16+02:00 - Seite 65Z

allows the vehicle-trailer combination to
stabilize.
The ESP ®
trailer stabilization is functional at
vehicle speeds above approximately 40 mph
(65 km/h) when the ESP ®
is switched on.GWarning!
The system will not be able to assist when the
trailer jackknifes
R if the ESP ®
has switched off due to a
malfunction
R on wet or icy roads
R on roads with slippery surface
R in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying of
the trailer.
