2014 MERCEDES-BENZ CLS-Class engine

If ESP
®
detects that the vehicle is deviating
from the direction desire dbythe driver, one
or more wheels are braked to stabilize the
vehicle .The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP ®
assists the driver when
pulling away on wet or slippery roads. ESP ®
can also stabilize the vehicle during braking.
If ESP ®
intervenes, the 0011ESP®
warning
lamp flashes in the instrumentc luster.
If ESP ®
intervenes:
X Do not deactivat eESP®
under any
circumstances.
X Only depres sthe accelerator pedal as far
as necessary when pulling away.
X Adapt your drivin gstyle to suit the
prevailing road and weathe rconditions.
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) ETS/4ETS traction control is part of ESP
®
.
Traction control brakes the drive wheels
individuall yifthey 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
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP ®
.

WARNING
If you deactivate ESP ®
,E SP ®
no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following. !
Avoid spinnin gthe driven wheels for an
extended period with ESP ®
deactivated.
You could otherwise damage the drivetrain.

OFF warning lamp in the
instrument cluster goes out.
ESP ®
is activated automatically when the
engine is started.
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving. The engine starts
automatically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. Example: if ESP ®
was
deactivated before the 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 0011ESP®
warning lamp in
the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehicle.
It may be best to deactivate ESP ®
in the
following 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 traction control is still activated.
R ESP ®
still provides support when you
brake.
R engine torque is not limited and the drive
wheels are able to spin. The spinning

i Observe the "Important safety notes"
section (Y page 66). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at aqualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Y page 267) as well as
displaym essages (Y page 240).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking. Driving safety systems
71Safety Z
