Geartronic: starting on slippery
surfaces
Selecting 3rd gear in Geartronic’s manual shifting mode can help provide better tractionwhen starting off on slippery surfaces. To doso:
1. Depress the brake pedal and move the gear selector to the side from D toward
+S– .
2. Press the gear selector forward and release it (this selects 2nd gear). Press the selector forward again and release itto select 3rd gear. The optional steeringwheel paddles can also be used; see theprevious section "Geartronic: steeringwheel paddles."
3. Release the brake pedal and press gently on the accelerator pedal.
Shiftlock override
If the vehicle cannot be driven, for example because of a dead battery, the gear selectormust be moved from the P position before
the vehicle can be moved 4
.
Lift away the rubber mat on the floor of the storage compartment behind the cen-ter console to expose the small openingfor overriding the shiftlock system.
Insert the key blade into the opening. Press the key blade down as far as possi-ble and keep it held down.
Move the gear selector from the P posi-
tion. For information on the key blade, see page 60.
All Wheel Drive: AWD 5
Your Volvo can be equipped with permanent All Wheel Drive, which means that power isdistributed automatically between the frontand rear wheels. Under normal driving condi-tions, most of the engine's power is directedto the front wheels. However, if there is anytendency for the front wheels to spin, an elec-tronically controlled coupling distributespower to the wheels that have the best trac-tion.

If the battery is dead, the electric parking brake cannot be applied or released. Connect an auxiliary battery if the battery voltage is too low, see page 119.5

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 functionsand cannot be switched off.
Spin control (SC)The spin control function is designed to helpprevent the drive wheels from spinning whilethe vehicle is accelerating.
Trailer Stability Assist – TSATrailer Stability Assist helps stabilize a vehiclethat is towing a trailer when the vehicle andtrailer have begun to sway. See page 288 formore information. This system is automatically deactivated if the driver selects
Sport mode.
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 driving by allowing more lateral movement of the rearwheels before DSTC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow 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.

Active chassis (Four C)
Active chassis, Four-C (Continuously Con- trolled Chassis Concept), regulates the cha-racteristics of the shock absorbers so that thevehicle's driving characteristics can beadjusted. There are three settings: Comfort,Sport and Advanced.
ComfortComfort mode offers a somewhat softer rideand the transmission shifts gears at lowerrpm. This mode is particularly suitable forlong-distance highway driving. The indicatorlight in the button will be on when this modeis selected.
SportIn this mode, the vehicle's body sway isreduced during cornering and steeringresponse is more immediate. The transmis-sion shifts up at higher rpm for sportier driv-ing. The indicator light in the button will be onto indicate that Sport mode has beenselected.
AdvancedIn this mode, body sway in curves is minimaland steering response is very direct. Gearshifting is done at high rpm in each gear fordynamic and active driving.
Operation
Chassis settings
Use the buttons in the center console to change setting. The setting in use when theengine is switched off is activated the nexttime the engine is started.
Adjustable steering force*
Steering force increases with the speed of the vehicle to give the driver enhanced sensitivity.At low speed the vehicle is easy to steer inorder to facilitate parking, etc. Steering force can be changed under

. Select Low, Medium or High. For a
description of the menu system, see page 201.
NOTE
This steering force level menu function cannot be accessed when the vehicle is inmotion.
NOTE
In certain situations, the power steering may become too warm and will have to betemporarily cooled down. While this ishappening, the power steering effect willbe reduced slightly and somewhat moreeffort may be required to turn the steeringwheel. If this occurs, a message will be displayed in the instrument panel.

NOTE
•When parking the vehicle with a trailer on a hill, apply the parking brakebefore putting the gear selector in
P.
Always follow the trailer manufactur-er's recommendations for wheelchocking.
• When starting on a hill, put the gearselector in
D before releasing the park-
ing brake.
• If you use the manual (Geartronic) shiftpositions while towing a trailer, makesure the gear you select does not puttoo much strain on the engine (usingtoo high a gear).
• The drawbar assembly/trailer hitchmay be rated for trailers heavier thanthe vehicle is designed to tow. Pleaseadhere to Volvo's recommended trailerweights.
• Avoid driving with a trailer on inclinesof more than 15%.
Trailer cableAn adapter is required if the vehicle's trailer hitch has a 13-pin connector and the trailerhas 7 pins. Use an adapter cable approvedby Volvo. Make sure the cable does not dragon the ground.
Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to help stabilize a vehicle that is towing a trailerwhen the vehicle and trailer have begun tosway and is part of the Dynamic Stability andTraction Control system (DSTC). See page144 for information on DSTC.
FunctionA vehicle towing a trailer may begin to swayfor various reasons. Normally this only occursat high speeds but, for example, if the traileris overloaded or if the load is unevenly dis-tributed in the trailer, there is risk of swayingat speeds between approximately 45-55 mph(70-90 km/h). Swaying may be caused by factors such as: •
The vehicle and trailer are hit by a sud- den, strong crosswind
• The vehicle and trailer are traveling on anuneven road surface or drive over a bump
• Sudden movements of the steering wheel
Facts about TSA
• TSA intervenes at speeds above approxi-mately 40 mph (60 km/h)
• The DSTC symbol (
) in the instru-
ment panel will flash when TSA is working
• If the driver switches off the DSTC sys- tem's Spin Control function, TSA will also be switched off (but will be on again thenext time the engine is started)
• TSA may not intervene when the vehicleand trailer begin to sway if the driver triesto compensate for the swaying motion bymoving the steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very diffi- cult to stop, which makes it difficult to controlthe vehicle and trailer. The TSA system continuously monitors the vehicle's movements, particularly lateralmovement. If the system detects a tendencyto sway, the brakes are applied individuallyon the front wheels, which has a stabilizingeffect on the vehicle and trailer. This is oftenenough to enable the driver to regain controlof the vehicle. If this is not adequate to stop the swaying motion, the brakes are applied to all of thewheels on the vehicle and on the trailer if it isequipped with brakes, and engine power istemporarily reduced. As the swaying motionbegins to decrease and the vehicle-trailerhave once again become stable, TSA will nowstop regulating the brakes/engine power andthe driver regains control of the vehicle.
