Automatic standby mode
Pilot Assist interacts with other systems, such asElectronic Stability Control. If any of these othersystems are not functioning properly, Pilot Assistwill automatically be deactivated.

WARNING
If this happens, the driver will be alerted by anaudible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
Pilot Assist switches automatically to standbymode if:
•the camera cannot detect the traffic lane'sside marker lines
•the vehicle ahead is not within a reasonable(detectable) distance
•the driver's hands are not on the steeringwheel
•the driver unbuckles the seat belt
•engine speed (rpm) is too high/low
•the wheels lose traction
•brake temperature is too high
•the parking brake is set
•The camera lens/radar sensor is covered bye.g., wet snow or if heavy rain interferes withradar waves

Collision warning
Warning light in the windshield
Pilot Assist can exert brake force that is equiva-lent to approximately 40% of the vehicle's totalbraking capacity.
In situations requiring more brake force than PilotAssist can provide and if the driver does notapply the brakes, an audible signal and warninglight will illuminate in the windshield to alert thedriver to react.

NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

WARNING
Pilot Assist only provides warnings for vehi-cles that its radar sensor and camera havedetected. For this reason, a warning may begiven later than expected or not at all. Thedriver should never wait for a warning beforeapplying the brakes.

Head-up-display *
A flashing symbol alerts the driver
If the vehicle is equipped with a head-up display,a flashing symbol in the windshield will alert thedriver.
NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

•the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that PilotAssist has the following limitations:
•High curbs, barriers and temporary obsta-cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
•The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
•Pilot Assist does not "see" pedestrians,animals, etc.
•Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.

Hands on the steering wheel
Pilot Assist only functions when the driver'shands are on the steering wheel, which is con-tinuously monitored by the system. If this is notthe case, the driver will be alerted by a text mes-sage in the instrument panel. If the driver's handsare not returned to the steering wheel, an audiblesignal will sound.
If the driver does not return his/her hands to thesteering wheel after the audible signal, Pilot
Assist will go into standby mode and must be
reactivated by pressing .

Time interval controls
Press to reduce the time interval to the vehi-cle ahead
Press to increase the time interval to thevehicle ahead
Distance indicator
In order to follow the vehicle ahead as smoothlyas possible, Pilot Assist allows the time interval tovary considerably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Pilot Assist increases the time intervalslightly.
•If Pilot Assist does not seem to react when itis put in active mode, this may be becausethe set time interval to the vehicle aheaddoes not allow an increase in speed.
•The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.

WARNING
•Only use a time interval that is suitable incurrent traffic conditions.
•A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

Maintaining/increasing the hybridbattery's charge while driving
In certain situations, it can be useful to controlthe hybrid battery's charge level while the vehicleis being driven. The hybrid battery functionsHold and Charge while driving are available inall drive modes.

The "Hold" and "Charge" function
buttons
These functions are activated from the centerdisplay's Function view.

Hold
Battery level sustained forlater use.
This function saves the hybridbattery's charge for use at alater time such as when drivingin an urban area or residentialneighborhood. Hold is available regardless of thehybrid battery's charge level.
The vehicle will function as in normal hybrid driv-ing and will use energy from e.g., regenerativebraking to support the gasoline engine.

Charge
Engine charges hybridbattery.
This function is only available when the hybridbattery's charge level is low and can recharge thebattery up to 33%, after which the Hold functionwill be activated automatically.
Symbol in the instrument panel
The symbol will appear in the instrumentpanel when either of these functions is activated.See also the article "Hybrid-related symbols andmessages" for additional information.

When the hybrid battery's charge level is low, thegasoline engine will start more often to help con-serve electrical energy. Charge the battery withthe charging cable as soon as possible.

PURE
This mode activates the electric motor only withas low energy consumption as possible and thelowest possible carbon dioxide emissions.
Ground clearance will be lowered to help reducewind resistance and certain climate system func-tions will be reduced.
Pure mode is available when the hybrid battery issufficiently charged. If the level gets too low, thegasoline engine will start.
The gasoline engine will also start:
•If the vehicle's speed goes above approx.78 mph (125 km/h)
•If the driver wants more response than theelectric motor alone can provide
•If factors such as cold weather, etc., affectthe system or components
To restart the climate system functions that havebeen reduced in the mode, press the AUTO ordefroster buttons.
In order to return to full functionality for all of thesystems that may be affected by Pure mode,select another drive mode or adapt the climatesystem functions using the INDIVIDUAL mode.
OFF ROAD
This mode helps maximize the vehicle's capacityto traverse difficult terrain or poor roads.
In OFF ROAD, ground clearance is maximized,the steering is light, All Wheel Drive and HillDescent Control are activated and a compassand altimeter will be displayed in the instrumentpanel.
This drive mode can only be activated at lowspeeds (the permissible speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and AWD willbe activated.
This mode is not intended for normal streetdriving.

CAUTION
OFF ROAD drive mode may not be used ifthe vehicle is towing a trailer without an elec-trical connection. This could result in damageto the pneumatic suspension system's bel-lows.
Due to the increased ground clearance, if theOFF ROAD mode was selected when the enginewas switched off, it will also restart in this mode.

AWD
This mode offers improved traction using four-wheel drive and is intended primarily for low-speed driving on slippery surfaces. However, it
also helps increase directional stability at higherspeeds.
In this mode, both the electric motor and the gas-oline engine are used continuously, which resultsin higher fuel consumption.
POWER
Power mode is intended for sportier, more activedriving.
This mode maximizes the combined effects ofthe electric motor and the gasoline engine andprovides power to all four wheels. Response topressure on the accelerator pedal is more imme-diate and the transmission shifts up at higherspeeds. Steering response is also more immedi-ate, the suspension is stiffer and lower groundclearance reduces body roll when cornering.
In this mode, both the electric motor and the gas-oline engine are used continuously, which resultsin higher fuel consumption.

Suspension leveling settings
Easy entry
The vehicle can be lowered to entering and exit-ing easier.
In the center display's Top view:
1.Tap Settings.
2.Tap My CarSuspension .
3.Select Easy Entry/Exit Control.
>When the vehicle is parked and theengine is turned off, the level is lowered.Level adjustment will stop if a side door isopened and will resume after a slightdelay when the door has been closed.When the engine is started and the vehi-cle begins to move, the level will be raisedto the height set by the selected drivemode.
If a door has been opened and closed, there maybe a slight delay before the leveling function willresume.

Turning off suspension and leveling control
In certain situations, this function has to beturned off, for example when lifting the vehicle ona jack to help avoid problems created by the dif-ference in levels in the pneumatic suspensionwhen the vehicle is raised.
1.Tap Settings in the center display's Topview.
2.Tap My CarSuspension .
3.Select Deactivate Suspension & LevelingControl.
Loading mode
Use the buttons in the cargo compartment toraise or lower the vehicle to make loading orunloading easier or when attaching a trailer.

Parking the vehicle
When parking, be sure that there is adequatespace above and below the vehicle since itsground clearance may vary, e.g., depending onthe ambient temperature, how the vehicle is loa-ded, if loading mode is being used or the drivemode selected after the engine is started.
The level may also be adjusted for a certain timeafter the vehicle has been parked to compensatefor possible height adjustments due to tempera-ture changes in the pneumatic suspension whenthe vehicle has cooled.
Transport
When transporting the vehicle on a ferry, train ora tow truck, it may only be secured (lashed)around the tires, not using any other chassiscomponents. Changes in the pneumatic suspen-sion may occur during transport that could nega-tively affect the lashing and result in damage.
