Start/Stop* - function and operation
Some engine and gearbox combinations are equipped with a Start/Stop function whichengages in the event of e.g. stationary trafficor waiting at traffic lights. The Start/Stopfunction is activated automatically when theengine is started with the key.
The Start/Stop function isactivated automatically whenthe engine is started with thekey. The driver is madeaware of this by the func-tion's symbol illuminating inthe combined instrumentpanel and the On/Off buttonlamp illuminating. All of the car's normal sys-
tems such as lighting, radio, etc. work as nor- mal even with an engine that has stoppedautomatically, except that some equipmentmay have the function temporarily reduced,e.g. the climate control system's fan speed orextremely high volume on the audio system.
Engine auto-stopThe following is required for the engine to auto-stop:
ConditionsM/A A
Declutch, set the gear lever in neu- tral position and release the clutchpedal - the engine stops automati-cally.M
Stop the car with the foot brake, and then keep your foot on thepedal - the engine auto-stops.A
AM = Manual gearbox, A = Automatic gearbox.
If the ECO function is acti- vated then the engine mayauto-stop before the car iscompletely stationary.
As verification and reminder that the engine is auto-stopped the com-bined instrument panel's symbol forthe Start/Stop function illuminates.

The Start/Stop function is disengaged until it is reactivated with the button or until the nexttime the engine is started with the key.
Start assistance HSAThe foot brake can also be released on anuphill slope to auto-start the engine - the HSA(p. 279) (Hill Start Assist) function preventsthe car from rolling backwards. HSA means that the pressure in the brake system remains temporarily available whilethe driver moves his/her foot from the brakepedal to the accelerator pedal for driving offwith the engine having stopped automatically.The temporary braking effect releases after afew seconds or when the driver depressesthe accelerator pedal.

ECO*
ECO is an innovative Volvo function for auto- matic-gearbox cars, capable of reducing fuelconsumption by up to 5%, depending on thedriver's driving style. The function gives thedriver the option of a more active environ-mentally conscious way of driving.
GeneralThe following are changedupon activation of the ECOfunction:
• Gearbox gearshift points.
• Engine management and response from the accelerator pedal.
• Start/Stop function - the engine can alsoauto-stop before the car has stopped tobeing fully stationary.
• The Eco Coast function is activated -engine braking ceases.
• Climate control system settings - someelectricity consumers are deactivated oroperate at reduced power.
NOTE
When the ECO function is activated, sev- eral parameters in the climate control sys-tem's settings are changed, and severalelectricity consumer functions are reduced- a press of the
AC button resets the cli-
mate control system, but then withreduced AC function.
ECO - Operation
ECO On/Off
ECO symbol
The ECO function is deactivated when the engine is switched off, and must therefore beactivated after each time the engine isstarted. There are exceptions for certainengines. However, it is easily verified bymeans of both the combined instrument panel
ECO symbol and the ECO button lamp
illuminating when the function is activated.
ECO function On or OffDisengaged ECO function is indicated by the combined instrument panel
ECO sym-
bol and the ECO button lamp extinguishing. The function isthen switched off until it isreactivated with the ECObutton.
Eco Coast - FunctionThe Eco Coast subfunction means in practice that engine braking is deactivated, meaning inturn that the car's kinetic energy is used tocoast for longer distances. When the driverreleases the accelerator pedal the gearbox isautomatically disengaged from the enginewhose speed is reduced to idling speed withminimum consumption. This function is intended for use in the event of an anticipated reduction in speed, e.g. toroll forward to an intersection or a red light. Eco Coast enables proactive driving where the driver can use the so-called "Pulse &Glide" technique and a minimum of braking. Combination On and Off A combination of Eco Coast and temporarily deactivated ECO function can also collec-tively contribute to reduced consumption.Accordingly:
• Active Eco Coast: Long coasting
without
engine braking = Low consumption

tion, see Key positions (p. 70) for more information.
2. Press the START button without
depressing the brake and/or clutch pedal.
3. Wait approx. 1 minute.
4. To start the engine: Depress the brake and/or clutch pedal and then press the START button again.
NOTE
Before filling with fuel in the event of fuel shortage:
• Stop the car on as flat/level ground as possible - if the car is tilting there is arisk of air pockets in the fuel supply.
Draining condensation from the fuel filter
The fuel filter separates condensation from the fuel. Condensation can disrupt engineoperation. The fuel filter must be drained at the intervals specified in the Service and Warranty Bookletor if you suspect that the car has been filledwith contaminated fuel. For more information,see Volvo service programme (p. 340).
IMPORTANT
Certain special additives remove the water separation in the fuel filter.

Catalytic converters
The purpose of the catalytic converters is to purify exhaust gases. They are located closeto the engine so that operating temperature isreached quickly. The catalytic converters consist of a monolith (ceramic or metal) with channels. The channelwalls are lined with a thin layer of platinum/rhodium/palladium. These metals act as cata-lysts, i.e. they participate in and accelerate achemical reaction without being used upthemselves.
Lambda-sond TM
oxygen sensorThe Lambda-sond is part of a control systemintended to reduce emissions and improvefuel economy (see Fuel consumption andCO2 emissions (p. 403)). An oxygen sensor monitors the oxygen con- tent of the exhaust gases leaving the engine.This value is fed into an electronic systemthat continuously controls the injectors. Theratio of fuel to air directed to the engine iscontinuously adjusted. These adjustmentscreate optimal conditions for efficient com-bustion, and together with the three-way cat-alytic converter reduce harmful emissions(hydrocarbons, carbon monoxide and nitrousoxides).

end up in the wrong lane or leave the car- riageway. The trailer stability assist continually monitors the car's movements, particularly lateralmovements. If snaking is detected, the frontwheels are individually braked. This serves tostabilise the car/trailer combination. This isoften enough to help the driver regain controlof the car. If snaking is not eliminated the first time the trailer stability assist comes into action, thecar/trailer combination is braked with allwheels and engine power is reduced. Oncesnaking has been gradually suppressed andthe car/trailer combination is stable onceagain, the system stops regulating and thedriver once again has full control of the car.For more information, see Stability and trac-tion control system (DSTC) - operation (p.176)
MiscellaneousThe trailer stability assist can engage withinthe speed interval 60-160 km/h.
NOTE
TSA function is switched off if the driver selects Sport mode, see Stability and
traction control system (DSTC) (p. 175).
The trailer stability assist may fail to engage if the driver uses sudden steering wheel move-ments to try to rectify the snaking because in such a situation the system cannot determinewhether it is the trailer or the driver that iscausing the snaking.
When the trailer stability assist isworking, the combined instrument
panel's DSTC symbol flashes.

Towing
During towing, one vehicle is towed by another vehicle using a tow rope.
IMPORTANT
Note that the car must always be towed with the wheels rolling forward. Do not tow the vehicle at speeds higher than 80 km/h or for distances in excess of80 km.
Find out the statutory maximum speed limit for towing before towing begins.
1. Unlock the steering lock by inserting the
remote control key in the ignition switch and giving a long press on the START/
STOP ENGINE button - key position II is
activated, see Key positions (p. 70) formore information about key positions.
2. The remote control key must remain in the ignition switch while the car is beingtowed.
3. Keep the towline taut when the towing vehicle reduces speed by holding yourfoot gently pressed on the brake pedal -thereby avoiding unnecessary jerking.
4. Be prepared to brake to stop.
