ESP MERCEDES-BENZ CLS 2014 Service Manual

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.

starting the engine or lights up while driving,
see (Ypage 266).

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.

When shifting down, the double-clutch
function is active regardless of the currently

function reduces load change reactions and
is conducive toasporty driving style. The

\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

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
workshopand have thefuel tankand fuel
lines drainedcompletely.
!Overfilling the fuel tank could damage the

!Take carenot to spill any fuel on painted
surfaces.You could otherwise damage the
paintwork.
!Useafilter when refueling fromafuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from

Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.

drivingstyle in termsofconsumption,taking
the actual and selected conditionsinto
consideration.Your driving style can
significantly influence the vehicle's
consumption.
The ECO display consistsofthree bars:
RAcceleration
RConstant
RCoasting
The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%.Ahigher
percentage indicatesamoreeconomical
driving style.
The ECO display doesnot indicate the actual
fuelconsumption andafixedpercentage
count in the ECO display doesnot indicate a
fixedconsumption figure.
Apart from driving style, consumption is
dependent on many factors such as,e.g.:
Rload
Rcheck
Rcoldstart
Rchoice of route
Relectrical consumers switched on
These factors are not taken into
consideration by the ECO display.
The evaluation of your driving styleiscarried
outusing the following three categories:
RAcceleration(evaluation of all
acceleration processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(assessment of driving behavior
at all times):
-The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
-The bar empties: fluctuations in speed
RCoasting(assessment of all deceleration
processes):
-The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
-The bar empties: frequent braking
iAn economical driving style specially
requires driving at moderate engine
speeds.
To achieveahigher value in the categories
AccelerationandConstant:
Robserve the gearshift recommendations.
Rdrive in drive programE.
iOn long journeys ataconstant speed, e.g.
on the highway, only the bar forConstant
will change.
iThe ECO displaysummaries the driving
characteristics from the start of the journey
to its completion. For this reason, the bars
change dynamically at the beginning of the
journey. On longer journeys, there are
fewer changes. For more dynamic changes,
carry outamanual reset.
