Pilot Assist*34
Pilot Assist can help the driver keep the vehi- cle in the current traffic lane by providingsteering assistance and maintaining an evenspeed and a set time interval to the vehicleahead.
How Pilot Assist worksThe Pilot Assist function is primarily intended for use on highways and other major roadswhere it can help provide a more comfortableand relaxing driving experience.
The camera/radar sensor monitors the distance to the vehicle ahead and detects lane markings.
Camera and radar sensor
Distance monitor
Lane marker line monitors The driver sets the desired speed and distance to the vehicle ahead. Pilot Assist monitors thedistance to the vehicle ahead and the trafficlane's side markers using the camera andradar sensor. The system maintains the settime interval to the vehicle ahead by automati-cally adjusting your vehicle's speed and keepsyour vehicle in its lane by providing steeringassistance. If the Curve Speed Assist (CSA)
* function is
activated, it may also affect the vehicle's speed. Pilot Assist's steering assistance is based on monitoring the direction of the vehicle aheadand the traffic lane's side marker lines. Thedriver can override Pilot Assist's steering rec-ommendations at any time and steer inanother direction, e.g. to change lanes or avoidobstacles on the road. If the camera/radar sensor cannot detect the lane's side marker lines or if Pilot Assist isunable for some other reason to clearly inter-pret the lane, Pilot Assist will temporarilydeactivate steering assistance until it can onceagain interpret the lane markings. However,the speed and distance warnings will remainactive. The driver will be alerted by slightvibrations in the steering wheel that the func-tion has been temporarily deactivated.
WARNING
Pilot Assist is deactivated automatically and resumes working without prior notice.
The color of the steering wheel symbol indicates thecurrent status of steeringassistance: • GREEN indicates that steering assistance is active
• GRAY (as shown in illustration) indicates thatsteering assistance is deactivated.
34 Depending on market, this function can be either standard or optional.

Lane Keeping Aid alerts the driver using vibrations in the steering wheel.
Depending on the settings used, Lane Keep- ing Aid functions in different ways:
Assist enabled: When the vehicle
approaches a lane marker line, the func- tion will actively steer the vehicle back intothe lane using light pressure on the steer-ing wheel.

Warning enabled: If the vehicle is about
to move over a lane marker line, the driver will be alerted by vibrations in the steeringwheel.
There is also an option for activating steeringassistance and alerts at the same time.
NOTE
When the direction indicators/turn signals are activated, the Lane Keeping Aid doesnot provide any warning or intervene withsteering.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.
Lane Keeping Aid does not intervene
Lane Keeping Aid does not intervene in sharp inside curves.
In certain cases, such as when a turn signal is used or when "straightening out" an insidecurve, Lane Keeping Aid will not provide steer-ing assistance or alerts.
Hands on the steering wheelSteering assistance with Lane Keeping Aidonly functions if the driver's hands are on thesteering wheel, which the system continu-ously monitors.
If the driver's hands are noton the steering wheel, anaudible signal will be givenand a message will instructthe driver to actively steer thevehicle:

Start knob in the tunnel console.
WARNING
Before starting:
Buckle your seat belt.
Adjust the seat, steering wheel and mirrors.
Make sure you can fully depress thebrake pedal.
The remote key is not physically used to startthe ignition because the vehicle is equippedwith the keyless Passive Start system. To start the vehicle:
1. The remote key must be inside the vehicle.
For vehicles with Passive Start, the key must be in the front section of the passen-ger compartment. With the optional key- less locking/unlocking function *, the key
can be anywhere in the vehicle.
2. Press and hold down the brake pedal 1
as
far as possible.
3. Turn the start knob clockwise and release. The control will automatically return to the original position.
WARNING
Never use more than one inlay mat at a time on the driver's floor. If any othertype of floor mat is used, remove theoriginal mat from the driver's seat floorbefore driving. All types of mats mustbe securely anchored in the attach-ment points in the floor. Make sure thefloor mat does not impede the move-ment of the brake pedal or acceleratorpedal in any way, as this could be aserious safety hazard.
Volvo's floor mats are specially manu-factured for your vehicle. They must beproperly secured in the attachmentpoints in the floor to help ensure theycannot slide and become trappedunder the pedals.
The starter motor will crank until the enginestarts or until overheating protection is trig-gered.
Error messagesIf the Vehicle key not found message is
shown in the instrument panel at start, place the remote key at the backup reader and thenmake a new start attempt.

Leveling control * and suspension
Self-leveling and suspension functions are controlled automatically.
Rear leveling control keeps the rear section of the vehicle at the same height regardless ofload. Leveling control may also remain activewhen the vehicle is parked.
Shock absorbers (Four-C)On vehicles equipped with Four-C, the shockabsorbers are adapted to the selected drive mode and the current vehicle speed. Theshock absorbers are normally set to help opti-mize comfort and are adjusted continuouslyaccording to the road surface and the vehicle'sacceleration, braking and cornering.
TransportingWhen transporting the vehicle on a ferry, trainor truck, only secure (lash) the vehicle aroundthe tires, not using any other parts of the chas-sis. Changes in the pneumatic suspension
may occur during transport, which couldadversely affect the lashing and result in dam-age.

Jump starting using another battery If the start battery is discharged, current from another battery can be used to start the vehi-cle.
Jumper cable connecting points. Engine compart- ment appearance may vary depending on vehiclemodel and equipment level.
To avoid short circuits or other damage, the following steps are recommended when jumpstarting the battery using another battery:
1. Put the ignition in mode 0.
2. Make sure the auxiliary battery (the bat- tery used to jump start the discharged battery) has a voltage of 12 volts. 3. If the auxiliary battery is in another vehicle,
turn off that vehicle's engine and makesure that the vehicles are not touchingeach other.
4. Clamp the red jumper cable onto the auxil- iary battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to pre- vent short circuits with other componentsin the engine compartment.
5. Fold back the cover over your vehicle'spositive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start terminal (2).
7. Clamp the black jumper cable onto the auxiliary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securely attached to help prevent sparks whilejump starting. 10. Start the engine of the assisting vehicle
and let it run for a few minutes at a higheridling speed than normal, about1500 rpm.
11. Start the engine of the vehicle with the dead battery.
CAUTION
Do not touch the connections between the cable and the vehicle during the startattempt. Risk of sparking.
12. Remove the jumper cables in the reverseorder ‒ first the black cables and then the
red cables. Make sure that none of the clamps of the black jumper cables come into contactwith either vehicle's positive (+) jump startterminals or either of the red jumpercable's connected clamps.

using this as a lever.
CAUTION
It is important that the towing eye is screwed in securely as far as possible.
To consider before using the towing eyelet
In certain conditions, the towing eyelet may be used to pull the vehicle onto a flat-bed tow truck. The vehicle's position andground clearance determines if this is pos-sible.
If the incline of the tow truck is too steepor if the ground clearance under the vehi-cle is insufficient, attempting to pull it up using the towing eyelet may result in dam-age.
If necessary, lift the vehicle using the towtruck's lifting device instead of using thetowing eyelet.
WARNING
No person or object should be behind the tow truck when the vehicle is lifted ontothe bed of the truck.
CAUTION
The towing eyelet is only intended for tow- ing on roads – not for pulling vehicles fromditches or any similar purpose involvingsevere strain. Call a tow truck for profes-sional assistance.
Removing the towing eyelet–Unscrew the towing eyelet after use and return it to its storage location in the foamblock. Replace the cover on the bumper.
