warning light MERCEDES-BENZ G-CLASS SUV 2015 Owner's Manual

XIf appropriate for the driving conditions,
engage the LOW RANGE off-road gear
( Y page 132).
Traction control is part of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP ®
.
Traction control is no longer active above a
speed of approximately 37 mph (60 km/h).
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Deactivating/activating ESP®
iObserve the "Important safety notes" sec-
tion ( Ypage 64).
GWARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
!Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You could otherwise damage the drivetrain.
X To deactivate: press button:until the
å warning lamp lights up in the instru-
ment cluster.
X To activate: press button :until the å
warning lamp goes out in the instrument cluster.
ESP ®
is activated automatically when the
engine is started.
iVehicles with the ECO start/stop func-
tion: the ECO start/stop function automat-
ically switches the engine off when the
vehicle comes to a stop. The engine starts
automatically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. For example, if ESP ®
was
deactivated before the engine was
switched off, ESP ®
remains deactivated
when the engine is switched on again.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R and are driving at above 37 mph (60 km/h)
(on AMG vehicles above 62 mph
(100 km/h)), ESP ®
still intervenes when
one wheel reaches its grip limit even
though it is deactivated.
iIf ESP ®
is deactivated and one or more
wheels start to spin, the ÷warning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehi-
cle.

Exterior lighting
Important safety notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations.
Driving abroad
Conversion to symmetrical low beam
Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country where the vehicle is registered. This prevents
glare to oncoming traffic. When using sym-
metrical lights, the edge of the road is not lit
as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Conversion to asymmetrical low beam
after returning
Have the headlamps converted back to asym- metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after
crossing the border again.
