Deactivating/activating the Pilot Assist*
Pilot Assist can be temporarily deactivated so that it is set in the standby mode and can bereactivated later.
Deactivating and setting Pilot Assist in
standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
To temporarily switch off Pilot Assist and set it in standby mode:
–Press the steering wheel button (2).
> Pilot Assist is set in standby mode - the symbol (8) in the driver display changes colour from WHITE to GREY and thestored speed in the centre of the speed-ometer changes from BEIGE to GREY.
...or...
–Press ◀ (3).
> Pilot Assist is switched off and changes to the adaptive cruise control in active mode.
In standby mode, the driver is no longer given anydriver steering recommendations and must con-trol both speed and distance him/herself. When Pilot Assist is in standby mode and the car drives too close to a vehicle ahead, the driver iswarned about the short distance by the DistanceWarning function instead (see reference to theheading "Distance Warning" at the end of thissection).
Standby mode on driver intervention
Pilot Assist is temporarily deactivated and set in standby mode if:
• the foot brake is used
• the gear selector is moved to
N position.
• the direction indicators are used for longerthan 1 minute .
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
• the clutch pedal is depressed forapprox. 1 minute - applies to cars with man-ual gearbox.
A temporary increase in speed with the accelera-tor pedal, e.g. during overtaking, does not affectthe setting - the car returns to the last storedspeed when the accelerator pedal is released. When the direction indicators are used, PilotAssist steering assistance is temporarily disen-gaged. When this is no longer the case, steeringassistance is automatically reactivated if thelane's side markings can still be detected.

Automatic standby mode
Pilot Assist is dependent on other systems, e.g. stability control/anti-skid ESC. If any of theseother systems stops working, Pilot Assist isswitched off automatically. In the event of automatic deactivation a signal will sound and a message is shown in the driver dis-play. The driver must then intervene and adaptthe speed and distance to the vehicle ahead. Automatic deactivation may occur if:
• the speed is below 5 km/h (3 mph) and Pilot Assist is uncertain whether the vehicle aheadis a stationary vehicle or an object, such as aspeed bump.
• the speed is below 5 km/h (3 mph) and thevehicle ahead turns off so that Pilot Assist nolonger has a vehicle to follow.
• speed is reduced to below 30 km/h(20 mph) - only applies to cars with manualgearbox.
• the driver's hands are not on the steeringwheel
• the driver opens the door
• the driver takes off the seatbelt
• engine speed is too low/high
• wheels lose traction
• brake temperature is high
• the parking brake is applied •
the camera and radar unit is covered by e.g.snow or heavy rainfall (camera lens/radiowaves are blocked).
Reactivating Pilot Assist from the
standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
–Press the steering wheel button (1).
> The speed is then set to the most recently stored speed.
NOTE
A marked speed increase may occur once the speed has been resumed by pressing steer- ing wheel button

Change of target and automatic braking with Pilot Assist *
In combination with automatic gearbox, Pilot Assist has functionality for change of target and braking at certain speeds.
Change of target
If the target vehicle in front suddenly turns then there may be stationary traffic in front.
When Pilot Assist is following another vehicle at speeds below 30 km/h (20 mph) and changes
target from a moving to a stationary vehicle, Pilot Assist will slow down for the stationary vehicle.
WARNING
When Pilot Assist is following another vehicle at speeds in excess of approx. 30 km/h
(20 mph) and the target is changed from a moving vehicle to a stationary vehicle, PilotAssist will ignore the stationary vehicle andinstead select the stored speed.
• The driver must then intervene him/ herself and brake.
Automatic standby mode with change of target
Pilot Assist is disengaged and set in standby mode: •when the speed is below 5 km/h (3 mph) and Pilot Assist is uncertain whether the tar-get object is a stationary vehicle or someother object, e.g. a speed bump.
• when the speed is below 5 km/h (3 mph)and the vehicle in front turns off so the PilotAssist no longer has a vehicle to follow.
Automatic brakingFor shorter stops in connection with inching for-ward in slow traffic or at traffic lights, driving isautomatically resumed if the stops do not exceedabout 3 seconds - if it takes longer before thecar in front starts moving again then the PilotAssist is set in standby mode with automaticbraking.
–Pilot Assist is reactivated in the following way:
• Press the steering wheel button
.
• Depress the accelerator pedal.
> Pilot Assist resumes following the vehicle ahead if it starts moving forward within 6 seconds.
NOTE
Pilot Assist can hold the car stationary for a maximum of 5 minutes - then the parkingbrake is applied and the function is disen-gaged. Before Pilot Assist can be reactivated, the parking brake must be released.

IMPORTANT
In certain situations, Pilot Assist steering assistance may have difficulty helping thedriver in the right way or it may be automati-cally deactivated - in which case, the use ofPilot Assist is not recommended. Examples ofsuch situations may be that: •the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits or inthe event of multiple sets of markings.
• edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
• the lane is narrow or winding.
• the lane contains ridges or holes.
• weather conditions are poor, e.g. rain,snow or fog or slush or impaired viewwith poor light conditions, back-lighting,wet road surface etc.
The driver should also note that Pilot Assisthas the following limitations: • High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane
markings, with a subsequent risk of con- tact between the car and such obstacles.The driver must ensure him/herself thatthe car is at a suitable distance from suchobstacles.
• The camera and radar sensor does nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects which completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is forcelimited, which means that it cannotalways help the driver to steer and keepthe car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed byPilot Assist and can turn the steering wheel tothe desired position.
Steep roads and/or heavy loadBear in mind that Pilot Assist is primarilyintended for use when driving on level road surfa-ces. The function may have difficulty in keepingthe correct distance from the vehicle ahead whendriving on steep downhill slopes - in which case,be extra attentive and ready to brake. Do not usePilot Assist with a heavy load or with a trailer con-nected to the car.
Miscellaneous
•Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Park Assist Pilot *
Active parking assistance (Park Assist Pilot - PAP) helps the driver to park in or leave a park-ing space.
PAP checks first if a space is sufficiently big and thereafter helps the driver to turn the steeringwheel and manoeuvre the car into the space. The centre display indicates with symbols, graph- ics and text the various operations to be carriedout and when to do so.
NOTE
The PAP function measures the space and steers the car - the driver's task is to:
• keep a close watch around the car
• follow the instructions in the centre dis-play
• change gear (reverse/forward)
• control and maintain a safe speed
• brake and stop.

11. Start the engine in the car with the dis-
charged battery.
IMPORTANT
Do not touch the connections between cable and car during the starting attempt. There is arisk of sparks forming.
12. Remove the jump leads in reverse order -first the black and then the red. Make sure that none of the black jump lead's clamps comes into contact with the car'spositive jump-starting point/donor battery'spositive terminal or the clamp connected tothe red jump lead.
WARNING
• The battery can generate oxyhydrogen gas, which is highly explosive. A spark canbe formed if a jump lead is connectedincorrectly, and this can be enough forthe battery to explode.
• The battery contains sulphuric acid, whichcan cause serious burns.
• If sulphuric acid comes into contact witheyes, skin or clothing, flush with largequantities of water. If acid splashes intothe eyes - seek medical attention imme-diately.

Gearbox
The gearbox is part of the car's driveline (power transmission) between engine and drive wheels.The function of the gearbox is to change thegear ratio depending on speed and powerrequirements.
There are two main types of gearbox, manual and automatic. The manual gearbox has six gears. The automatic gearbox can have either eight gears or six gearsdepending on which engine the car is equippedwith. The number of gear changes means thatthe engine's torque and power range can beused effectively. It is also possible to select gears manually with the automatic gearbox. The driver display respec-tively shows which gear or gear position is cur-rently in use.
IMPORTANT
To prevent damage to any drive system com- ponents, the working temperature of thegearbox is checked. If there is a risk of over-heating, a warning symbol illuminates in thedriver display and a text message is shown -follow the recommendation given.
Symbols in the driver displayIf a fault should occur in the gearbox, the driver display shows a symbol and a message.

STARTING AND DRIVING

Drive position - D
D is the normal driving position. Shifting up and
down takes place automatically based on the level of acceleration and speed. The car must be stationary when changing gear from R position to
D position.
Manual gearshift mode - M
The manual gearshift mode can be selected at any time while driving. The car engine-brakeswhen the accelerator pedal is released. Select manual gearshift mode by moving the gear selector sideways from position D to the
end position at " ±". The driver display shows
which gear is engaged at the time.
• Press the gear selector forwards to "
+"
(plus) to change up one step and release it.
• Press the gear selector backwards to "
–"
(minus) to change down one step and release it.

.
The gearbox automatically shifts down if the speed decreases to a level lower than appropri-ate for the selected gear, in order to avoid jerkingand stalling. To return to automatic gear changing, press the gear selector sideways to the end position at D.
Kick-downWhen the accelerator pedal is pressed all the way to the floor (beyond the position normallyregarded as full acceleration) a lower gear isimmediately engaged. This is known as kick-down. If the accelerator is released from the kick-down position, the gearbox automatically changes up. Kick-down is used when maximum accelerationis needed, such as for overtaking.
Safety function
To prevent over-revving of the engine, the gear- box control program has a protective downshiftinhibitor. The gearbox does not permit downshifting/kick- down which would result in an engine speed highenough to damage the engine. Nothing happensif the driver still tries to shift down in this way athigh engine speed – the original gear remainsengaged. When kick-down is activated the car can change one or more gears at a time depending onengine speed. The car changes up when theengine reaches its maximum speed in order toprevent damage to the engine.

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.
