Red Key - restricted remote key
*
A Red Key makes it possible for the vehicle owner to set limitations for certain vehicleproperties. The limitations are intended topromote safe use of the vehicle, e.g. when itis loaned out.
For a Red Key, it is possible to define the vehi- cle's maximum speed, set speed remindersand limit the audio system's volume. Severalof the driver support systems will also alwaysbe active. Otherwise, the Red Key functions inthe same way as a standard remote key. These restrictions are intended to help reduce the risk of accidents and help the driver feelmore secure when handing over the vehicle toe.g. a young driver, parking attendant or work-shop.
Driver profile for Red KeyA Red Key is linked to a specific Red Keydriver profile, and when it is active the key'ssettings cannot be changed. It is also not pos-sible to switch to another driver profile, as thisrequires a regular remote key. The Red Key driver profile is activated when the vehicle is unlocked using a Red Key with-out a regular remote key nearby.
NOTE
If the vehicle changes owners, the vehicle must be locked and then unlocked for anew driver profile to be activated.
Ordering a Red KeyOne or more Red Key can be ordered from a Volvo retailer. A total of twelve keys can beprogrammed and used for the same vehicle.Up to ten may be restricted keys, but at leasttwo must be standard remote keys.

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.

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.
