2014 MERCEDES-BENZ CLS ESP

The Start/Stop button must be inserted in the
ignition lock and the SmartKey must be in the
vehicle.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button,the engine starts
immediately.
The Start/Stop button can be removed from
the ignition lock. Then, you can insert the
SmartKey into the ignition lock.
iYou do not have to remove the Start/Stop
button from the ignition lock when you
leave the vehicle. You should, however,
alwaystake the SmartKey with you when
leaving the vehicle. As long as the
SmartKey is in the vehicle:
Rthe vehicle can be started using the
Start/Stop button and
Relectrically powered equipment can be
operated.

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.

Changing gear
The automatic transmission shifts to the
individual gears automatically when it is in

Rthe selected drive program (Ypage 159)
Rthe position of the accelerator pedal
Rthe road speed
Driving tips
AMG vehicles
When shifting down, the double-clutch
function is active regardless of the currently
selected drive program. The double-clutch
function reduces load change reactions and
is conducive toasporty driving style. The
sound generated by the double-clutch
function depends on the drive program
selected.

Shift ranges
Introduction
iYou can restrictorderestrict the shift
range by using the steering wheel paddle
shifters.
When the automatic transmission is in
positionD,itispossible to restrictorexpand
the shift range (Ypage 162).
The shift range selectedisshown in the
multifunctiondisplay. The automatic
transmission shiftsonly as far as the selected
gear.
Shiftrange:
You can use the engine'sbraking
effect
\nYou can use the braking effect of
the engine on downhill gradients
and for driving:
Ron steep mountain roads
Rin mountainous terrain
Rin arduous conditions
To use the braking effect of the
engine on extremely steep downhill
gradients and on long downhill
stretches
Restricting theshiftrange
XPull the left-handsteeringwheel paddle
shifter.
The automatic transmission shifts down
one gear and restrictsthe shift range to the
relevant gear.
iIf the engine exceeds the maximum
engine speed when shifting down, the
automatic transmission protectsagainst
engine damage by not shifting down.
iIf the maximum engine speed for the shift
range is reached and you continue to
accelerate, the automatic transmission
shifts up, even if the shift range is
restricted. This prevents the engine from
overrevving.
Extending the shift range
XPull the right-hand steering wheel paddle
shifter.
The shift range is derestricted.
Clearing the shift range restriction
XPull and hold the right-hand steering wheel
paddle shifter untilDis shown again in the
multifunction display.
The automatic transmission shifts from the
current shift range directly toD.
Selecting the ideal shift range
XPull the left-hand steering wheel paddle
shifter and hold it in position.
The automatic transmission shifts to the
gear which allowsoptimum acceleration
and deceleration. To do this, the automatic
transmission shifts down one or more
gears.

!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the
ignition if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could result in damage to the
fuel system and the engine. The repair
costs are high. Notifyaqualified specialist
