ESP MERCEDES-BENZ GL 2010 Workshop Manual

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.
LOW RANGE mode
The LOW RANGE mode is available on
vehicles with enhanced off-road package.
In the following situations you should switch
to the LOW RANGE mode:
R during off-road driving
R before driving through water
R when towing up or down on steep gradients
With LOW RANGE selected, the engine’s
power delivery and the shifting behavior of
the automatic transmission are adjusted.
Furthermore, the ABS, the ESP ®
, and the
4-ETS functions especially adapted to off-
road travel are activated.
For more information on off-road driving, see
“Off-road driving” ( Y page 262).
For information on driving safety systems
during LOW RANGE mode, see “Driving safety
systems” ( Y page 61).
Gear ranges
There are two possible settings.
HIGH
RANGERoad position for all normal
driving situations.
(LOW RANGE mode off)LOW
RANGEOff-road position for
traveling on rough terrain.
(LOW RANGE mode on)
Also use the off-road
position when driving on-
road on steep gradients,
especially when towing a
trailer.
LOW RANGE acts by raising
the engine’s gear ratio. The
vehicle travels at roughly
third the speed compared to
when in HIGH RANGE
position, leading to an
increase in the engine’s
drive power.GWarning!
Always wait until the procedure of shifting
from HIGH RANGE to LOW RANGE – and from
LOW RANGE to HIGH RANGE – has been
entirely completed. During this procedure do
not turn off the engine or shift the automatic
transmission into another gear.
If you do not wait until the shifting procedure
has been entirely completed then it might not
be correctly performed. The transfer case
might be in neutral, thus interrupting the
transfer of power between the engine and the
drive axle.
The vehicle is then freely movable, even if a
gear has been selected, and could
unintentionally be set into motion –
particularly on up – or downhill grades. This
could lead to an accident and cause injury to
yourself and others.
Please observe related messages appearing
in the multifunction display.

and rear axle differential to improve vehicle
traction.
The center differential compensates for
differences in wheel rotation between the
front and rear axle.
The rear axle differential compensates
differences between the rear wheels.
i At the front axles, the 4-ETS system
compensates for any traction problems.
For more information on off-road driving, see
“Off-road driving” ( Y page 262).
A few words about differentials and
differential locks
When a vehicle negotiates a turn, wheels on
the outside of the curve must travel farther
and rotate faster than the inside wheels. The
differential, the operation of a set of gears
that allows the powered wheels in a vehicle
to turn at different speeds, makes this
essential function possible.
The drawback is that the differential also
sends most of the engine’s power to the
wheel with the least load or strain on it. For
example, if one of a vehicle’s powered wheels
sits on a patch of snow and spins because
there is no traction, all of the engine’s power
will go to that wheel because the power will
take the path of least resistance. Meanwhile,
the opposite wheel, sitting on dry pavement
where it could get enough grip to start the
vehicle moving, sits idle because it receives
no power.
The 4-ETS addresses this problem and
provides for good control and steering ability
by automatically slowing the slipping wheel
and thus increasing the power to the other
non-slipping drive wheels to get the vehicle
moving. The ESP ®
and the 4-ETS in this
vehicle feature such intelligent limited-slip
differential technology, ideally suited for on-
road and light off-road driving. Transfer case
position LOW (Y page 120) also enhances off-
road driving capabilities.
More extreme off-road conditions may call for
another solution, engaging a differential lock
or preventing the differential from operating
altogether. This vehicle comes with two
differential locks: transfer case (center) and
rear. Each can be engaged simply by
operating the rotary switch located on the
center console ( Y page 123). When the
transfer case (center) differential is locked,
the combined (or average) speed of the front
wheels is identical to the combined rear
wheel speed. When the rear differential is
locked, both rear wheels turn at the same
speed, independent of the individual torque.
Please be aware that engaging the differential
locks will significantly reduce the steering
ability of the vehicle.
For your safety and the safety of others and
to prevent damage to the vehicle, the
differential locks must not be engaged when
driving on paved roads. It is important to
understand that during on-road/paved
driving, differentials are absolutely necessary
for providing the essential control and
steering ability of the vehicle. The differential
locks, therefore, must not be engaged when
driving on paved roads and should only be
used to the extent necessary to negotiate off-
road conditions which cannot be handled by
the systems (the 4-ETS, the ESP ®
, and the
transfer case in LOW RANGE mode) this
vehicle comes equipped with.
Switching differential locks
! If the differential locks are engaged,
accelerate gently when setting the vehicle
in motion.
Only operate the vehicle on a single axle
dynamometer if the axle not being driven is
jacked up or the associated propeller shaft
is disconnected.
Otherwise the transmission could be
damaged.

The AUTO mode is adequate for most driving
situations since the center differential is
locked and released as required.
iAt speeds up to 19 mph (30 km/h), it is
possible to manually lock the differential
locks for driving on rough terrain.
XStart the engine.
The center differential lock is in AUTO
mode. The indicator lamp on adjustment

A message indicating that the center
differential lock is in AUTO mode appears in
the multifunction display when the off-road
menu is selected. For selecting the off-road
menu, see the “Controls in detail” section
(Y page 131).
Center and rear axle differential locksGWarning!
Never drive on a paved surface with the center
and rear axle differential locks manually
engaged. Ability to steer the vehicle is greatly
reduced when the differential locks are
manually engaged, increasing the risk of an
accident.
For safety reasons, the locks are
automatically released at a vehicle speed
above 31 mph (50 km/h). Nevertheless, you
should only manually lock the differential if
absolutely necessary because engaged locks
will restrict the vehicle drivetrain while
cornering and cause the vehicle to chatter.
This could cause you to lose control of the
vehicle and cause an accident.
! The differential locks must not be
engaged manually when towing the vehicle
or spinning the wheels.
The differential locks should only be engaged
manually if traction is insufficient in AUTO
mode.
The differential locks can be engaged in the
sequence 3, 4 (Y page 123) up to a speed
of 19 mph (30 km/h).

Cruise control
The cruise control maintains the speed you

remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
RThe use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
RThe use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
RDeactivate the cruise control when driving

The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.
GWarning!
When the cruise control is braking, the brake
pedal is retracted (i.e. depressed
automatically). The pedals’ range of motion
must not be impeded by any obstacles:
RDo not place any objects in the footwell.
RMake sure that the floormats and carpets
are securely in place.
RDo not rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
