display MERCEDES-BENZ CLS 2014 Owner's Guide

You can use this function to set the
headlamps to change betweenlow 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 detectsany other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.

(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM levelisrecommended.
RSet thetemperaturetof72‡(22 †).
ROnly use the"Windshield defrosting"
function briefly until thewindshield is clear
again.
ROnly use air-recirculation modebriefly, e.g.
if there are unpleasantoutside odorsor
when inatunnel. The windows could
otherwise fog up, since no fresh air is drawn
intothevehicleinair-recirculation mode.
RUse theZONEfunction to adopt the

to heat or ventilate the vehicle interior
when the ignition is switched off. The
residual heat function can only be activated
or deactivated with the ignition switched
off.

Setting climate control to automatic
Points to observe before use
In automatic mode, the set temperature is
maintained automatically ataconstant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-
dehumidification" function, the air inside the
vehicle will not be cooled. The air inside the
vehicle will also not be dehumidified. The
windows can fog up more quickly. Therefore,
deactivate the cooling with air-
dehumidification function only briefly.

Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshift the automatic transmission out of
parking position P.
Rstartingthe engine.
There isarisk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
isarisk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There isarisk
of fire.
Carry out regular checkstomake sure that
there are no flammable foreign materials in
the engine compartmentorinthe exhaust
system.
!Do not depress the accelerator pedal
when startingthe engine.
General notes
iThe catalytic converter is preheated for
up to 30 seconds afteracold start. The
sound of the engine may change during this
time.
Automatic transmission
XShift the transmission to positionP.
The transmission position display in the
multifunction display showsP.
iYou can also start the engine when the
transmission is in positionN.
Starting procedurewith the SmartKey
iTo start the engine using the SmartKey
instead of KEYLESS-GO, pull the Start/
Stop button out of the ignition lock.
XTurn the SmartKey to position3in the
ignition lock (Ypage 147) and release it as
soon as the engine is running.
Using KEYLESS-GO to startthe engine
iThe Start/Stop button can be usedto
start the vehicle manually without inserting
the SmartKey into the ignition lock. The
Start/Stop button must be inserted in the
ignition lock and the SmartKey must be in
the vehicle. This mode for starting the
engine operates independently of the ECO
start/stop automatic engine start function.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(Ypage147).

Pulling away
Automatic transmission
GWARNING
If the engine speed is above the idling speed
and you engage transmission positionDor
R,the vehicle could pull away suddenly. There
isarisk of an accident.
When engaging transmission positionDorR,
always firmly depress the brake pedal and do
not simultaneously accelerate.
!Ifawarning tone sounds and the
Release Park. Brakemessage appears
in the multifunction display,the parking
brake is still applied. Release the parking
brake.
XDepress the brake pedal and keep it
depressed.
XShift the transmission to positionDorR.
XRelease the parking brake (Ypage 169).
XRelease the brake pedal.
XCarefullydepress the accelerator pedal.
iIt is only possible to shift the transmission
from positionPto the desired position if
you depress the brake pedal. Only then is
the parking lock released. If you do not
depress the brake pedal, you can move the
DIRECT SELECT lever but the parking lock
remains engaged.
iThe vehicle locks centrally once you have
pulledaway.The locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic
locking feature (Ypage 232).
iUpshifts take place at higher engine
speeds afteracold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill startassist
GWARNING
Afterashort time, hill start assist will no
longer brake your vehicle and it could roll
away. There isarisk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle forashort time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
XTake your foot off the brake pedal.
The vehicle is then held for aboutasecond.
XPull away.
Hill start assist will not function if:
Ryou are pulling away onalevel road or on
adownhill gradient.
Rthe transmission is in positionN.
Rthe parking brake is applied.
RESP®is malfunctioning.
ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is
stopped under certain conditions.
The engine startsautomatically when the
driver wants to pull away again. The ECO
start/stop function thereby helps you to
reduce the fuel consumption and emissions
of your vehicle.
