2014 MERCEDES-BENZ CLS-Class front light

You can use this function to set the
headlamps to change betwee
nlow beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detect sany other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.

The 0010 indicator lamp in the
multifunction display lights up if it is dark
and the light sensor activates the low-beam
headlamps.
If you are driving at speeds above
approximately 28 mph (45 km/h): The headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you are driving at speeds above
approximately 35 mph (55 km/h) and no
other road users have been detected:
The high-beam headlamps are switched on
automatically. The
0015indicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below
approximately 30 mph (45 km/h) or other
road users have been detected or the roads
are adequately lit:
The high-beam headlamps are switched off
automatically. The 0015indicator lamp in
the instrument cluster goes out. The 0010

Braking
Important safety notes G
WARNING
If yo ushift down on aslipper yroads urface in
an attempt to increas ethe engine's braking
effect,t he drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on aslippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting
early to alower gear. This allowsy ou to take
advantage of the engine braking effect and
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
braking effect,ad rive wheel may not turn
for some time, e.g. on aslippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Ben zwarranty.
Do no tdepress the brake pedal continuously
while the vehicle is in motion ,e.g. causing the
brakes to rub by constantly applying light
pressure to the pedal. This results in
excessive and premature wear to the brake
pads.
On long and steep downhill gradients, you
must select shift range 1,2or 3in good time.
This is especially important if the vehicle is
laden.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the brakin gsystem can overheat .This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident. Never use the brake pedal as
afootrest .Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately, but
drive on for ashort while. This allows the
airflow to cool the brakes more quickly.
Wet roads If you have driven for
along time in heavy rain
without braking ,there may be adelayed
reaction from the brakes when braking for the
first time. This may also occur after the
vehicle has been washed or driven through
deep water.
You have to depress the brake pedal more
firmly. Maintain agreater distanc efrom the
vehicle in front.
After driving on awet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will
warm up the brake discs, thereby drying them
more quickly and protecting them against
corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads,
alayer of salt
residue may form on the brake discs and
brake pads. This can result in asignificantly
longer braking distance.
R Brak eoccasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginnin gand end of ajourney.
R Maintain agreater distanc etothe vehicle
ahead. 172

sensor system. DISTRONIC PLUS brakes
automaticallysot hat the set speed is not
exceeded.
Change into alower gear in good time on long
and steep downhill gradients. This is
especially important if the vehicle is laden. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is arisk
of ac ollision, you will be warned visually and
acoustically.D ISTRONIC PLUS cannot
prevent acollision without your intervention.
An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster. Brake immediately in
order to increase the distance to the vehicle
in front or take evasive action provided it is
safe to do so.
For DISTRONIC PLUS to assist you, the radar
sensor system must be operational.
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and 120 mph (Canada:
200 km/h). If avehicle is driving in front of
you, it operates in the speed range between
0m ph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked aboutt his.
