2010 MERCEDES-BENZ CLS COUPE warning lights

If ESP
®
intervenes, the ÷warning lamp
flashes in the instrument cluster. G
Risk of accident
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt yourd riving style to suitt he prevail-
ing road and weather conditions.
Otherwise, the vehicle could go into a skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Switch the ignition off when:
R the parking brake is being tested using a
dynamometer
R the vehicle is being towed with the front/
rear axle raised
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
! Do not tow vehicles with 4MATIC with the
front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) 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. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
Deactivating/activating ESP ®
(except
AMG vehicles) ESP
®
is activated automatically when the
engine is started.
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 G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply.E SP®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
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 bette rgrip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®

the vehicle to a limited degree if the vehicle
starts to skid or a wheel starts to spin.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R the engine's torque is restricted to a limited
degree 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.

tion)
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
Risk of accident
If EBD has malfunctioned, the braking system
remains available with full brake boosting
effect .However, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident .You should therefore adapt your
driving style to the different handling charac-
teristics. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (Y page 165) and
hill start assist (Y page 131). For further
information, see Driving tips (Y page 149). PRE-SAFE

61Safety Z

This function will issue a warning at speeds of
around 30 km/h or more if:
R
for a period of several seconds, the dis-
tance to the vehicle in fronti s too short for
the speed at which you are travelling. The
· distance warning lamp in the instru-
ment cluster will light up.
R you are rapidly approaching the vehicle in
front. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrument cluster.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning. G
Risk of accident
Pay particular attention to the traffic condi-
tions if the ·distance warning lamp in the
instrument cluster lights up or an intermittent
warning tone sounds. If necessary, brake or
manoeuvre to avoid an obstacle.
If the driver and passengers have fastened
their seat belts, PRE-SAFE ®
Brake can also
can also perform the following at speeds of
above approximately 30 km/h:
R brake the vehicle automatically from a
speed of up to approximately 200 km/h
R trigger preventative passenger protection
measures (PRE-SAFE ®
) G
Risk of accident
PRE-SAFE ®
Brake is only an aid to assist you
when driving. You are responsible for main-
taining a safe distance from other vehicles,
the vehicle's speed and for braking in good
time. Always pay attention to the traffic con-
ditions. Otherwise, you may recognise dan-
gers too late, cause an accident and injure
yourselfa nd others.
With the help of the rada rsensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time. If you approach an obstacle
and PRE-SAFE ®
Brake detects a risk of a col-
lision, the system will initially alert you both visually and acoustically. If you do not brake
or steer, the vehicle will at first automatically
brake slightly. In the event of an increased
risk of a collision, PRE-SAFE
®
is activated
(Y page 40). If the risk of collision remains
and you do not brake, take evasive action or
accelerate significantly, the vehicle may per-
form automatic emergency braking. G
Risk of accident
Only clearly detected obstacles will trigger a
warning and initiate braking assistance by
PRE-SAFE ®
Brake.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or the sensors are cov-
ered
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example in multi-storey car parks
PRE-SAFE ®
Brake does not react to persons,
animals, oncoming vehicles, crossing traffic
or when cornering.
PRE-SAFE ®
Brake may not detect narrow
vehicles such as motorcycles and vehicles
driving on a different line. G
Risk of accident
Depending on the current speed, PRE-SAFE ®
Brake decelerates your vehicle by up to
4 m/s 2
before performing possible emer-
gency braking. This is equivalent to approx-
imately 40 % of the maximum braking power
of the vehicle. You must additionally apply the
brakes yourself in order to preven tacollision
or minimis ean impact. Automatic emergency
braking is not performed until immediately
prior to an accident in the event that you are
unable to avoid one by, for instance, taking
evasive action.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a col-
lision, you must apply the brakes yourself. 62

Important safety notes
For reasons of safety, Mercedes-Ben zrecom-
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. Notes on driving abroad
Convert to symmetrical dipped beam
when driving abroad: switch the headlamps
to symmetrical dipped beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is reg-
istered. This prevents oncoming traffic from
being dazzled. Symmetrical lights do not illu-
minate as large an area of the edge of the
carriageway.
Convert the headlamps as close to the border
as possible before driving in these countries
(Y page 207).
Convert to asymmetrical dipped beam
after returning: convert the headlamps back
to asymmetrical dipped beam as soon as pos-
sible after crossing the border when returning
(Y page 207).
Vehicles with Intelligent Light System: if
the headlamps are converted to symmetrical
dipped beam, not all light functions are avail-
able. "Motorway mode" and the "extended
range foglamps" are deactivated. Light switch

Active light function The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Active:
when the lights are switched on. Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better vis-
ibility in tight bends, for example. It can only
be activated when the dipped-beam head-
lamps are switched on.
Active:
R
if you are driving at speeds below
40 km/h, the cornering light function is
activated either by the turn signal or by the
steering wheel being turned.
R if you are driving at speeds between
40 km/h and 70 km/h ,the cornering light
function is activated by the steering wheel
being turned.

Important safety notes
Xenon bulbs G
Risk of injury
Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric con-
tacts on xenon bulbs. Therefore, never
remove the cover from xenon bulbs.
Do not change xenon bulbs yourself, but have
them replaced at a qualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure 104
