Important safety notes G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine. Automatic transmission X

Starting procedure with the key i
To start the engine using the key instead
of KEYLESS-GO, pull the Start/Stop button
out of the ignition lock.
X To start a petrol engine: turn the key to
position 3in the ignition lock
(Y page 129) and release it as soon as the
engine is running.
X To startad iesel engine: turn the key to
position 2in the ignition lock
(Y page 129).
The % preglow indicator lamp in the
instrumen tcluster lights up.
X When the %preglow indicator lamp
goes out, tur nthe key to position 3
(Y page 129) and release it as soon as the
engine is running.
i You can start the engine without preglow
if the engine is warm.
i You can also use the touch-start function.
To do this, turn the key to position 3
(Y page 129) and release it immediately.
The engine then starts automatically.
Using KEYLESS-GO to startt he engine G
Risk of injury
You rvehicle can be started using a valid KEY-
LESS-GO key. For this reason, children should
never be left unsupervised in the vehicle.
Always take the key with you when leaving the
vehicle, even if you are only leaving it for a
short time.
i The Start/Stop button can be used to
start the vehicle manually without inserting
the key into the ignition lock. The key must 130

be in the vehicle and the Start/Stop button
must be inserted in the ignition lock .This
mode for starting the engine operates inde-
pendently of the ECO start/stop automatic
engine start function.
X Depress the brake pedal and keep it
depressed.
X To startap etrol engine: press the Start/
Stop button (Y page 129) once.

Automatic transmission i
It is only possible to shift the transmission
from position Pto the desired position if
you depress the brake pedal. Only then is
the parking lock released.
X Depress the brake pedal and keep it
depressed.
X Shif tthe transmission to position Dor R.
X Release the parking brake (Y page 148).
X Release the brake pedal.
X Carefully depress the accelerator pedal.
i The vehicle locks centrally once you have
pulled away.T he locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic lock-
ing feature (Y page 209).
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill starta ssist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It holds the vehicle for a short 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 depress it before the vehicle begins to
roll. G
Risk of accident
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.
X Take your foot off the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
X Pull away.
Hill start assist will not function if:
R you are pulling away on a level road or a
downhill gradient.
R the transmission is in position N.
R the parking brake is applied.
R ESP ®
is malfunctioning. ECO start/stop function
General notes The ECO start/stop function is only available
for the CLS 350 BlueEFFICIENCY and
CLS 63 AMG models.
AMG vehicles:
the ECO start/stop function
is only available in the Cdrive program.
The ECO start/stop function switches the
engine off automatically when the vehicle
stops moving.
The engine starts automatically when you pull
away again. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle. Driving

Risk of accident and injury
If the engine is switched off and the ECO sym-
bol is shown in green in the multifunction dis-
play, the engine has been switched off auto-
matically. All of the vehicle's systems remain active. If you open the door, unfasten your
seat belt or remove your foot from the brake
pedal, the engine will automatically start.T
he
vehicle may begin moving. You could suffer
serious or even fatal injury or cause an acci-
dent resulting in injury or death.
Never leave the vehicle while the ECO symbol
in the multifunction display is shown in green
or yellow. Always secure the vehicle against
rolling away before leaving it.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
Automatic engine switch-off The ECO start/stop function switches the
engine off automatically if the vehicle is
braked to a standstill and the brake remains
depressed with the transmission in position
D or N.
i You can still activate HOLD when the vehi-
cle is stationary, even if the engine has
been switched off automatically .Itis then
not necessary to continue applying the
brakes during the automatic stop phase.
When you depress the accelerator pedal,
the engine starts automatically and the
braking effect of the HOLD function is deac-
tivated. Depress the accelerator pedal
carefully, as the engine must be started
first.
The engine is only switched off if:
R the outside temperature is within the range
which is suitable for the system.
R the engine is at normal operating temper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the battery is sufficiently charged.
R the system detects that the windscreen is
not misted up when the air-conditioning
system is switched on.
R the bonnet is closed.
R the front door is closed and the seat belt is
fastened. 132

Problem Possible causes/consequences and
M Solutions
Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop, e.g. a Mercedes-Benz Service Centre.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 268). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X At coolant temperatures under 120 †, drive on to the nearest
qualified specialist workshop e.g. to a Mercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Automatic transmission
Important safety notes
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you to lose control of your vehicle and cause an
accident. Automatic transmission

Changing gears
The automatic transmission shifts to the indi-
vidual gears automatically when it is in trans-
mission position D.This automatic gearshift-

R a shift range restriction, if selected
R the selected drive program (Y page 138)
R the position of the accelerator pedal
R the road speed Driving tips
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts AMG vehicles When shifting down, the double-clutch func-
tion is active regardless of the currently selec-
ted drive program. The double-clutch function
reduces load change reactions and is condu-
cive to a sporty driving style. The sound gen-
erated by the double-clutch function depends
on the drive program selected.
