Start/Stop
With the Start/Stop function, the engine switches off temporarily when the car has stop-ped e.g. at traffic lights or in a traffic queue, andthen starts again automatically when the journeyis resumed.
Start/Stop is one of several energy-saving func- tions intended to reduce fuel consumption, whichin turn helps to reduce exhaust emissions. The system makes it possible to adopt an envi- ronmentally-conscious driving style by allowingthe car to engine auto-stop when possible.

• Conditions for the Start/Stop function(p. 398)
Using the Start/Stop function The Start/Stop function temporarily switches off the engine when stationary and then restarts itautomatically when the journey is resumed.
The Start/Stop function is available when the engine is started and can be activated if certainconditions have been met. The driver display indi-cates whether the function is available, active orunavailable, see heading "Symbols in driver dis-play" below. All of the car's normal systems such as lighting, radio, etc. work normally, even when the engine isauto-stopped. However, some equipment mayhave its output temporarily reduced, e.g. the cli-mate control system's fan speed or extremelyhigh volume on the audio system.
Auto-stopThe following is required for the engine to auto-stop:

With automatic gearbox
• Stop the car with the foot brake and then keep your foot on the brake pedal - theengine stops automatically.
With manual gearbox
• Declutch, set the gear lever in neutral posi-tion and release the clutch pedal - theengine stops automatically.
In drive mode
Eco or Comfort3 , the engine may
auto-stop before the car is completely stationary. With the
Adaptive cruise or Pilot Assist func-
tion activated, the engine will autostop after approximately three seconds. See the section "Conditions for Start/Stop func- tion".
AutostartThe following is required for the engine to auto-start: With automatic gearbox
• Release the brake pedal - the engine will autostart and you can continue driving. On anuphill gradient hill start assist (HSA) engages, which prevents the car from rollingbackwards.
• When the
Auto hold function is activated,
auto-start is delayed until the accelerator pedal is depressed.
• When the
Adaptive cruise or Pilot Assistfunction are activated, the engine will autos- tart when the accelerator pedal is depressed, or by pressing the
button on the left
keypad of the steering wheel.
• Maintain foot pressure on the brake pedal and depress the accelerator pedal - theengine auto-starts.
• On a downhill gradient: Release pressure onthe brake pedal slightly so that the carbegins to roll - the engine will auto-start aftera slight speed increase.

Drive mode ECO
Driving mode ECO mode optimises the car's
driving characteristics for more fuel efficient and environmentally-conscious driving.
Use this drive mode to save fuel and the environ- ment. The following properties are adapted for Eco driv- ing:
• Gearbox gearshift points 8
.
• Engine management and response from theaccelerator pedal.
• The Eco Coast 9
freewheel function is acti-
vated and engine braking is deactivatedwhen the accelerator pedal is released atspeeds between 65 and 140 km/h(40 and 87 mph).
• Some of the climate control system's set-tings work at reduced power or are deacti-vated.
• The driver display shows information in anECO gauge which facilitates environmentally-conscious and fuel-efficient driving.
Selecting ECO modeThe Eco mode is deactivated when the engine isswitched off, and it must therefore be activatedafter each time the engine is started. The driver display shows ECO when the function is acti-vated.

Driving mode ECO in the
centre display's function view.
–Press the button in order to activate the function.
> An indicator in the button illuminates when the function is activated.
Freewheel function Eco Coast 10The freewheel function Eco Coast means in prac- tice that engine braking ceases, meaning in turnthat the car's kinetic energy is used to freewheelfor longer distances. When the driver releasesthe accelerator pedal the gearbox is automaticallydisengaged from the engine whose speed isreduced to idling speed with reduced consump-tion. The function is best used where it is possible to freewheel a long way, e.g. roads with a slightdownhill gradient or when there is a predictablespeed reduction to freewheel into a zone with alower speed limit.
Activating the freewheel function
The function is activated when the accelerator pedal is fully released, in combination with thefollowing parameters:
• Drive mode
Eco is activated.
• The gear selector is in
D position.
• Speed within the range of approx. 65-140 km/h (40-87 mph).
• The road's downhill gradient is not steeperthan approx. 6%.
The driver display shows
COASTING when the
freewheel function is being used.
Limitations
The freewheel function is not available if:
• Engine and/or gearbox are not at normal operating temperature.
• The cruise control is activated.
• The gear selector is moved from the
D posi-
tion and the manual position.
• The speed is outside the range ofapprox. 65-140 km/h (40-87 mph).
• The road's downhill gradient is steeper thanapprox. 6%.
• Manual gear changing is performed with the steering wheel paddles
*.
Deactivating and switching off the freewheel function
In certain situations it may be desirable to deacti- vate or switch off the function in order to useengine braking. Examples of such situations maybe on steep downhill gradients or before animminent overtaking manoeuvre - in order to beable to do it in the safest way possible. Deactivate the freewheel function as follows:
• Actuate the accelerator or brake pedal.
• Move the gear selector to manual position.
• Changing gear with steering wheel paddles
*.
Switch off the freewheel function as follows:
• Change drive mode
*, or switch off the
Driving mode ECO in the function view.
Even without the freewheel function, it is possible to freewheel for short distances. This, in turn,reduces consumption. However, for the best fueleconomy it is better to have the freewheel func-tion activated and be able to freewheel for longerdistances.
