Deactivating/activating ESP

WARNING
If you deactivat eESP®
,E SP ®
no longer sta-
bilises the vehicle. There is an increased risk
of skidding and an accident.
Only deactivat eESP®
in th esituation sdescri-
bed in th efollowing. X
To switch off: press button:.
The å ESP®
OF Fw arnin glamp in the
instrumen tcluster lights up.
X To switch on: press button:.
The å ESP®
OFF warnin glamp in the
instrumen tcluster goes out.
ESP ®
is activated automatically when the
engin eisstarted.
The ECO start/stop fun ction switches the
engin eoff automaticall yifthe vehi cles tops
moving. When pulling away again, the engine
start sautomatically. ESP ®
remain sinits pre-
viousl yselected status. Example: if ESP ®
was
deactiva tedb efor ethe engine was switched
off ,ESP ®
remains deactivated when the
engine is switched on again.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in
th ei nstrumen tcluster flashes. In such situa-
tions, ESP ®
will not stabilise th evehicle. It may be best to deact
ivateESP®
in the fol-
lowing situations:
R when using sno wchains
R in deep snow
R on sand or gravel
If you deactivate ESP ®
:
R ESP ®
no longe rimproves driving stab ility.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R engine torque is not limited and the drive
wheels are abl etospin. The spinnin gofthe
wheels resu ltsinac utting action for better
traction.

trailer stabilisation G
WARNING
If roa dand weather conditions are poor,
trailer stabilis ation will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with ahigh centre of gravit ycan
tip over before ESP ®
can detect this. There is
ar isk of an accident.
Always adap tyour driving style to the prevail-
ing road and weather conditions.
If your vehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/
trailer combination by depressin gthe brake
firmly. Driving safety systems

R Befor etackling steep downhill gradients,
select shift range 1.
Do not shift int otransmission position N

vehicle using the servic ebrake .Ifthe gradient

ent-climbing capabilit yisavailable.
i If th eload on the fron taxle is reduced
whe npulling away on asteep uphill slope,
the fron twheels hav eatendency to spin.
4ETS recognises this and brakes the
wheels accordingly. The rear wheel torque
is increased and it is easier to pull away.
Hilltops When driving up an uphill gradient, slightly

epressure on th eaccelerator immedi-
atel ybefor ereachin gthe brow of the hill.
Make use of the vehicle' sown impetus to
travel over the brow.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of ahill
R the vehicle from travelling too quickly down
the other side.
Driving downhill R
Driv eslowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight. Oth-
erwise, the vehicle could slip sideways, tip
and overturn.
R Befor etackling steep downhill gradients,
select shift range 1.
R Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line
of fall.
R Check that the brakes are working normally
after along downhil lstretch.
