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.

STARTING AND DRIVING
* Option/accessory.427
•
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.

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.

Low Speed Control
*
The low-speed function, Low Speed Control (LSC), facilitates and improves control and trac-tion on rough roads and slippery surfaces, e.g.when towing a trailer on grass or up boat ramps. In vehicles equipped with drive mode control *,
the function is included in the Off Road drive mode.
Low Speed Control is designed for driving on rough roads and when towing trailers at lowspeeds, up to approximately 40 km/h (25 mph). When driving at low speeds, LSC prioritizes low gears and all-wheel drive to help avoid wheel spinand improve traction on all wheels. The accelera-tor pedal will be less responsive to improve trac-tion and speed control at low speeds. The function is activated together with Hill Descent Control (HDC), which makes it possibleto control speed going down steep hills using theaccelerator pedal and reduces the need to usethe brake pedal. The system makes it possible tomaintain a low and uniform speed when drivingdown steep hills.

Hill Descent Control *
The function for assisting when driving downhill, Hill Descent Control (HDC), is a low-speedfunction with increased engine braking. Thefunction makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients by only using the accelerator pedal,without applying the brakes. In vehicles equipped with drive mode control *,
the function is included in the Off Road drive mode.
HDC is designed for driving on rough roads at low speeds and downhill gradients with slipperyor otherwise difficult road surfaces. The driverdoes not need to use the brake pedal but caninstead focus on steering.
WARNING
HDC is only intended to be a supplementary braking aid and it does not function in all sit-uations. The driver is always ultimately responsible for operating the vehicle in a safe manner.
FunctionHill Descent Control allows the vehicle to move forward or backward at very low speeds assistedby the brake system. The driver can increase thespeed by pressing the accelerator pedal. Whenthe accelerator pedal is released, the vehicle will return to very low speed regardless of how steepthe hill is and without the brakes needing to beapplied. The brake lights will illuminate when thefunction is activated. The driver can brake to stop or slow the vehicle at any time by depressing the brake pedal. HDC is activated along with Low Speed Control (LSC), which facilitates and improves traction andcontrol on rough and slippery surfaces. The sys-tem is intended to be used at low speeds, up toapproximately 40 km/h (25 mph).
To keep in mind when using HDC
•
If the function is switched off while driving ona steep downhill gradient, braking effect willbe gradually reduced.
• HDC can be used in gear positions
D and R,
and in manual gears 1 or 2.
• It is not possible to manually shift to thirdgear or higher when HDC is active.
NOTE
When LSC with HDC is activated, the feel of the accelerator pedal and engine responsewill change.
NOTE
This drive mode is not designed to be used for normal street driving.
NOTE
The function is deactivated when driving at high speeds and must be reactivated at lowerspeeds if so desired.
