Select the drive mode that is best suited to the current driving conditions. Keep in mind that notall drive modes are available in all situations. To change drive mode:
1. Press the DRIVE MODE control.
> A pop-up menu will appear in the center display.
2. Roll the wheel upward or downward to the desired drive mode.
3. Press the drive mode control or tap its button in the center display to confirm the selection.
> The selected drive mode is shown in theinstrument panel. If a drive mode is grayed out in the pop-up menu, it cannot be selected.

ECO drive mode
The Eco drive mode optimizes the vehicle's driv- ing characteristics for more fuel-efficient andeco-friendly driving.
Use this mode to save fuel and promote eco- friendly driving. When ECO mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points.
• Engine control and accelerator pedalresponse.
• Eco Coast functionality is activated andengine braking is disabled when the acceler-ator pedal is released at speeds between65 and 140 km/h (40 and 87 mph).
• Some of the climate system settings will bereduced or switched off.
• Information will be shown in the ECO gaugein the instrument panel to help promotemore eco-friendly and economical driving.
Coast function Eco CoastEco Coast essentially deactivates engine braking,allowing the vehicle's kinetic energy to be used to roll greater distances. When the driver releases the accelerator pedal, the transmission is auto- matically disengaged from the engine. Enginespeed is reduced to idling speed to reduce fuelconsumption. This function is most effective in driving situa-tions where the vehicle can roll freely for a longdistance, e.g. on roads with slight downgrades orwhen a decrease in speed is anticipated, such aswhen approaching an area with a lower speedlimit.
Activating Eco Coast
The function is activated when the accelerator pedal is fully released and the following condi-tions are met:
• Eco drive mode is activated.
• The gear selector is in
D.
• The vehicle's speed is approximately65-140 km/h (40-87 mph).
• The gradient of the downgrade is less thanapproximately 6%.
COASTING will be displayed in the instrument
panel when Eco Coast is being used.
Limitations
Eco Coast is not available if:
• The engine and/or transmission are not at normal working temperatures.
• The gear selector is moved from
D to manual
shifting mode.
• The vehicle's speed is not within the65-140 km/h (40-87 mph) range.
• The gradient of the downgrade is more thanapproximately 6%. •
The steering wheel paddles
* are being used
for manual shifting.
Deactivating and turning off Eco Coast
In certain situations, it may be advisable to deac- tivate or turn off Eco Coast so that engine brak-ing can be used. These situations might includedriving down steep hills or before passinganother vehicle to help ensure this can be doneas safely as possible. Deactivate Eco Coast by:
• Pressing the accelerator or brake pedal.
• Moving the gear selector to manual mode.
• Using the steering wheel paddles
* to shift.
Turn off Eco Coast by:
• Switching drive mode
* or switching off drive
mode Eco in Function view.
It is possible to roll short distances even without Eco Coast in order to help conserve fuel. How-ever, for the best fuel economy, Eco Coast shouldbe activated and used to roll longer distances.
Cruise control Eco CruiseWhen cruise control is activated in the Eco drivemode, the vehicle's acceleration and decelerationwill be slower than in other drive modes to helpfurther conserve fuel. Because of this, the vehi-cle's actual speed may be slightly above or belowthe set speed.

STARTING AND DRIVING
* Option/accessory.423
•
On a level road, the vehicle's actual speed may differ from the set speed when cruisecontrol is active and the vehicle is coasting.
• On a steep uphill gradient, the vehicle'sspeed is reduced until the transmissiondownshifts. Reduced acceleration is then ini-tiated in order to reach the set speed.
• On a downhill gradient in which the vehicle iscoasting, the vehicle's actual speed may beslightly above or below the set speed. Thefunction uses engine braking to keep the setspeed. If necessary, the normal brakes arealso applied.
ECO gauge in the instrument panelThe ECO gauge indicates how economical cur-rent driving is:
• A low reading in the green area of the gaugeindicates economical driving.
• A high reading is shown when driving is noteconomical, e.g. heavy braking or rapid accel-eration.
The ECO gauge also has an indicator showinghow a reference driver would drive in the samedriving situation. This is shown by the shortpointer in the gauge.
Eco gauge in 12" instrument panel *.
Eco gauge in 8" instrument panel.
ECO ClimateIn Eco mode, ECO climate is automatically acti- vated in the passenger compartment to helpreduce energy consumption.
NOTE
When the ECO function is activated, settings for certain climate system and electricity con-suming functions are reduced. Some of thesesettings can be reset manually, but full func-tionality will only be restored by switching off the ECO function or adapting the
Individual*
drive mode to full climate system functionality.
If condensation forms on the windows, tap the max defroster button, which will function normally.

Temporarily deactivating the Start/Stop function
In certain situations, it may be advisable to tem- porarily turn the Start/Stop function off.
To turn off Start/Stop, tap theStart/Stop function button in
the center display's Function view. The indicator light in thebutton will go out when thefunction has been turned off.
The function will remain turned off until:
• it is reactivated
• the drive mode is changed to Eco or Comfort
• the engine is restarted.

Conditions for the Start/Stopfunction Certain conditions must be met for Start/Stop to function.
If any condition is not met, this will be indicated in the instrument panel.
The engine does not auto-stopThe engine will not auto-stop if: •
the vehicle has not reached a speed of ca 10 km/h (6 mph) after starting.
• after several auto-stops, the speed mustagain exceed approximately ca 10 km/h(6 mph) before the next auto-stop.
• the driver's seat belt is unbuckled.
• the start battery's charge is below the mini-mum level.
• the engine is not running at its normal oper-ating temperature.
• the ambient temperature is under approxi-mately -5 °C (23 °F) or over approximately30 °C (86 °F).
• windshield heating is activated.
• the climate system settings and the actualclimate in the passenger compartment differ.
• the vehicle is backing up.

•
High levels of condensation on the inside of the windows.
• the climate system settings and the actualclimate in the passenger compartment differ.
• Electrical current consumption is temporarilyhigh or the start battery's charge is below theminimum level.
• The brake pedal is pumped repeatedly.
• The hood is open.
• The vehicle begins to roll or increases speedslightly if the engine auto-stopped before thevehicle was at a standstill.
• The driver's seat belt is unbuckled with the gear selector in the

• The driver's door is opened with the gearselector in
D. An audible signal and a text
message informs the driver that the ignition is on.
