–Pull one of the paddles toward the steering wheel and then release.
" -": Shift down one gear.

Manual deactivation in gear position D
–Deactivate the paddles by pulling the right paddle (+) toward the steering wheel and
holding it until the number of the current gear is no longer displayed in the instrumentpanel.
Automatic deactivation
In gear position D, the steering wheel paddles
are deactivated after a short period of time if they are not used. The number of the current gear willno longer be displayed in the instrument panel. Ifengine braking is currently being used, the pad-dles will remain active until engine braking stops. In gear position M, the paddles will not activate
automatically.

ECO
•Adapt the vehicle for more fuel-efficient and eco-friendly driving with Eco mode.
In this mode, the Start/Stop function is activated,the ground clearance is lower to reduce air resis-tance and certain climate settings are reduced. The instrument panel has an ECO gauge to facili- tate fuel-efficient driving.
OFF ROAD
• Maximizes the vehicle's ability to traverse dif- ficult terrain or poor roads.
In this mode, ground clearance is high, steering islight, and all-wheel drive and Hill Descent Controlare activated. The Start/Stop function is deacti-vated. This mode can only be activated at low speeds. The permitted speed range will be shown in thespeedometer. If this speed is exceeded, Off roadmode will be deactivated and another drive modeactivated. In Off road mode, a compass will be displayed between the speedometer and the tachometer inthe instrument panel.
NOTE
This drive mode is not designed to be used for normal street driving.
NOTE
Due to the increased ground clearance, if the OFF ROAD mode was selected when theengine was switched off, the suspension willlower when the engine is restarted.
CAUTION
Do not use the OFF ROAD drive mode when towing a trailer without an electrical connec-tion. This could result in damage to the pneu-matic suspension system's bellows.
DYNAMIC
• Dynamic mode is designed to provide sport- ier driving characteristics and a faster accel-eration response.
Gear shifting will be faster and more distinct andthe transmission will prioritize gears with a highertraction force. Steering response is faster, suspension is stiffer and ground clearance is lower to help reducebody roll when cornering. The Start/Stop function is deactivated.
INDIVIDUAL
• Customizes drive mode to personal preferen- ces. Select one of the drive modes as a basis andadjust the settings to achieve your preferred driv-ing characteristics. These settings will be storedin your driver profile. Individual drive mode is only available if it has been activated in the center display.Settings view

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.
• The suspension's self-leveling function
* will
lower ground clearance to help reduce windresistance.
• 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 usedto roll greater distances. When the driver releasesthe accelerator pedal, the transmission is auto-matically disengaged from the engine. Engine speed 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.

Activating and deactivating ECOdrive mode using the functionbutton
Vehicles equipped with drive mode controls in the tunnel console have a function button forEco drive mode in the center display's Functionview.
When the engine is switched off, ECO mode is deactivated and must therefore be reactivated each time the engine is started. ECO will be dis-
played in the instrument panel when the function is activated.

display's Function view
–Tap the Driving Mode ECO button to acti-
vate or deactivate the function.

Start/Stop function
Start/Stop is a function that temporarily switches off the engine when the vehicle has stopped,e.g. at a traffic light or in heavy traffic, and thenstarts it again automatically when the brakepedal is released.
The Start/Stop function reduces fuel consump- tion, which helps to reduce exhaust emissions. The system makes it possible to drive more eco- nomically and climate-smart by letting the engineauto-stop when appropriate.

Driving with the Start/Stop function
Start/Stop is a function that temporarily turns off the engine when the vehicle is stationary andthen automatically starts it again when the vehi-cle starts moving.
The Start/Stop function is available when the engine is started and can be activated if certainconditions are met. The instrument panel indi-cates if the function is available, active or notavailable. All of the vehicle's ordinary systems, such as lighting, radio, etc. function normally when theengine has been auto-stopped. Certain functionsmay be temporarily reduced, however, such asthe climate system's blower speed or extremelyhigh audio system volume.
Auto-stopTo auto-stop the engine:
• Stop the vehicle by applying the brakes andkeep the brake pedal depressed. The enginewill auto-stop.
In Eco or Comfort 5
drive mode, the engine may
auto-stop before the vehicle has completely stop-ped. With Adaptive Cruise Control or Pilot Assist acti- vated, the engine will auto-stop after approxi-mately three seconds.
5 Normal start mode.

Auto-startThe following conditions must be met for the engine to auto-start. •Release the brake pedal. The engine will auto-start and the vehicle can be driven. Onan uphill gradient, Hill Start Assist (HSA) willactivate to help prevent the vehicle from roll-ing backward.
• When Auto-hold is activated, auto-start willbe delayed until the accelerator is pressed.
• When Adaptive Cruise Control or Pilot Assistare activated, the engine will auto-start whenthe accelerator pedal is depressed or the
button on the left-side steering wheel
keypad is pressed.
• Maintain pressure on the brake pedal and press the accelerator pedal. The engine willauto-start.
• On a downhill gradient: Release the brakepedal slightly so that the vehicle begins toroll. The engine will auto-start after a slightincrease in speed.
