Electric parking brake
An electric parking brake has the same func- tion as a manual parking brake.
NOTE
•A faint sound from the parking brake's electric motor can be heard when theparking brake is being applied. Thissound can also be heard during theautomatic function check of the park-ing brake.
• The brake pedal will move slightlywhen the electric parking brake isapplied or released.
Low battery voltageIf the battery voltage is too low, the park- ing brake cannot be applied or released. Connect an auxiliary battery if the battery voltage is too low, see page 119.
Applying the electric parking brake
Parking brake control
1. Press firmly on the brake pedal.
2. Push the control. >The
symbol in the instrument
panel flashes while the parking brake is being applied and glows steadily whenthe parking brake has been fullyapplied.
3. Release the brake pedal and ensure that the vehicle is at a standstill.
4. When the vehicle is parked, the gear selector must be in position P.
NOTE
• In an emergency the parking brake can be applied when the vehicle is movingby holding in the control. Braking willbe interrupted when the acceleratorpedal is depressed or the control isreleased.
• An audible signal will sound during thisprocedure if the vehicle is moving atspeeds above 6 mph (10 km/h).
Parking on a hill
•
If the vehicle is pointing uphill, turn the front wheels so that they point away fromthe curb.

Introduction
The Dynamic Stability and Traction Control system (DSTC) consists of a number of func-tions designed to help reduce wheel spin,counteract skidding, and to generally helpimprove directional stability.
CAUTION
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel spin by transferring power from a drivewheel that begins to lose traction to thewheel on the opposite side of the vehicle (onthe same axle). TC is most active at low speeds.This is one of DSTC's permanent functions and cannot be switched off.
Active Yaw Control (AYC)This function helps maintain directional stabil-ity, for example when cornering, by brakingone or more of the wheels if the vehicleshows a tendency to skid or slide laterally. This is one of DSTC's permanent functions and cannot be switched off.
Spin control (SC)The spin control function is designed to helpprevent the drive wheels from spinning whilethe vehicle is accelerating.
Operation
Sport modeThe stability system is always activated and cannot be switched off. However, the driver can select
Sport mode,
which offers more active driving characteris- tics. In this mode, the engine managementsystem monitors movement of the acceleratorpedal and steering wheel for sportier drivingby allowing more lateral movement of the rearwheels before DSTC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose sand, it may be advisable totemporarily use
Sport mode for maximum
tractive force. If the driver releases pressure on the acceler- ator pedal, DSTC will also activate to helpstabilize the vehicle. To switch to Sport mode:
1. Press the My Car button in the center
console control panel and select
My S80
DSTC in the menu.
2. Unselect the symbol and leave the menu by pressing EXIT.
> This puts DSTC in Sport mode.
Sport mode remains active until the driver
switches it off in the menu or until the engine is switched off. DSTC will return to normalmode when the engine is restarted.

WARNING
The stability system is intended to help improve driving safety. It supplements, butcan never replace, the driver's judgmentand responsibility when operating the vehi-cle. Speed and driving style should alwaysbe adapted to traffic and road conditions.

Road sign information (RSI)*
04
138* Option/accessory, for more information, see Introduction.
Introduction
Examples of readable road signs Road Sign Information (RSI) is a feature that helps the driver see road signs with the pos-ted speed limit. If the vehicle passes a sign showing the speed limit, this will be displayed in the centerconsole.
WARNING
RSI does not function in all situations and is only intended to provide supplementaryinformation. The driver is always responsible for oper- ating the vehicle safely.
Operation
Speed limit information
When RSI registers a road sign showing the speed limit, this sign is displayed as a symbolon the instrument panel.
Settings in MY CAR
Possible settings in MY CAR Displaying the speed limit indication can be deactivated. To do so:
• Deselect the alternative in
MY CAR
SettingsCar settingsRoad Sign
Information or cancel by pressing EXIT.
Speed alertThe driver can opt to be alerted if the vehicle exceeds the posted speed limit by more than3 mph (5 km/h). The alert is given when thesymbol with the posted speed limit in theinstrument panel begins to flash. To activate speed alert:
• Check the Speed alert box in
MY CAR
SettingsCar settingsSpeed alertor cancel by pressing EXIT.
Limitations
RSI's camera has the same limitations as the human eye. See page 166 for more informa-tion about the camera's limitations. Signs that indirectly indicate the speed limit (such as a sign with a town's name and thepermitted speed limit) will not be registeredby RSI. Other factors that may interfere with RSI include:
• Faded signs
• Signs located in a curve
