2014 MERCEDES-BENZ CLS lights

If ESP®detects that the vehicle is deviating
from the direction desiredbythe 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, theESP®warning
lamp flashes in the instrumentcluster.
If ESP®intervenes:
XDo not deactivateESP®under any
circumstances.
XOnly depressthe accelerator pedal as far
as necessary when pulling away.
XAdapt your drivingstyle to suit the
prevailing road and weatherconditions.
iOnly 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
individuallyifthey 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®.
Deactivating/activating ESP®(except
AMG vehicles)
GWARNING
If you deactivate ESP®,ESP®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 spinningthe driven wheels for an
extended period with ESP®deactivated.
You could otherwise damage the drivetrain.
XTo deactivate:(Ypage 227).
The ESP®OFF warning lamp in the
instrument cluster lights up.
XTo activate:(Ypage 227).
The ESP®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, theESP®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:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
If you deactivate ESP®:
RESP®no longer improves driving stability.
Rtraction control is still activated.
RESP®still provides support when you
brake.
Rengine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produceacutting effect for better
traction.

limited degree.
When SPORT handling mode is activated:

Rengine torque is only restricted toalimited
degree, and the drive wheels are able to

cutting effect for better traction.
Vehicles with ECO start/stop function: the
ECO start/stop function switches the engine
off automatically when the vehicle comes to
astop. The engine startsautomatically when

EBD (electronic brake force
distribution)
iObserve the "Important safety notes"
section (Ypage 66).
GWARNING
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 ataqualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Ypage 267) as well as
displaymessages (Ypage 240).
EBD monitors and controls the brake
pressure on the rear wheels to improve
driving stability while braking.

In order to maintain the appropriatedistance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
Due to the nature of the system, particularly
complicated driving conditionsmay cause

vehicle, have the configurationand operation
of the radarsensorschecked ataqualified
specialist workshop. This also applies to
collisions at low speeds where thereisno
visible damage to the frontofthe vehicle.
Function
XTo activate/deactivate:activate or

board computer (Ypage 228).
If the PRE-SAFE®Brake is not activated, the

symbol appears in the multifunction
display.
If you approachavehicle in front very quickly,
this function warns you fromaspeed of
approximately4mph (7 km/h). An
intermittent warning tone sounds and the
distance warning signal lamp in the
instrumentcluster lightsup.
XBrake immediately to defuse the situation.
or
XTake evasiveaction provided it is safe to do
so.
Fromaspeed of approximately4mph
(7 km/h), if the driver and frontpassenger
have fastened their seat belts, PRE-SAFE®
Brakecan brake the vehicle automatically at
speeds up to approximately 124 mph
(200 km/h).
You can preventthe intervention of the PRE-
SAFE®Brakeatany time by:
Rdepressingthe accelerator pedal further.
Ractivating kickdown.
Rreleasing the brake pedal.
The brakingaction of PRE-SAFE®Brakeis

will alert you both visually and acoustically. If
you do not brake or takeevasive action,the
system will warn you by automatically braking
the vehicle gently. If thereisanincreased risk
of collision, preventative passenger
protection measures (PRE-SAFE®)are
activated (Ypage 54). Ifarisk of collision
remains at speeds of over 20 mph
(30 km/h) and you do not brake, takeevasive
action or significantly accelerate, automatic
brakingmay be performed up to and including
emergency braking. Automatic emergency
