Start/Stop* - the engine auto-starts
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. An auto-stoppedengine may restart in certain cases withoutthe driver having decided that the journeyshould continue. In the following cases the engine also starts automatically if the driver has not depressedthe clutch pedal (manual gearbox) or takeshis/her foot off the brake pedal (automaticgearbox):

WARNING
If  and  illuminate at the same
time, there may be a fault in the brake sys- tem. If the level in the brake fluid reservoir is normal at this stage, drive carefully to thenearest workshop and have the brake sys-tem checked - an authorised Volvo work-shop is recommended. If the brake fluid is below the  MIN level in
the brake fluid reservoir, do not drive fur- ther before topping up the brake fluid. The reason for the loss of brake fluid must be investigated.

Foot brake - anti-lock braking system
The anti-lock braking system, ABS (Anti-lock Braking System), prevents the wheels fromlocking up during braking. The function allows steering ability to be maintained, and it is easier to swerve to avoida hazard for example. Vibration may be felt inthe brake pedal when this is engaged and thisis normal. A short test of the ABS system is made auto- matically after the engine has been startedwhen the driver releases the brake pedal. Afurther automatic test of the ABS system maybe made when the car reaches 10 km/h. Thetest may be experienced as pulses in thebrake pedal.

Foot brake - emergency brake lights and automatic hazard warningflashers
Emergency brake lights are activated to alert vehicles behind about sudden braking. Thefunction means that the brake light flashesinstead of - as in normal braking - shining witha constant glow. Emergency brake lights are activated at speeds above 50 km/h in the event of suddenbraking. After the car's speed has beenslowed below 10 km/h the brake light returnsfrom flashing to the normal constant glow -while at the same time the hazard warningflashers (p. 86) are activated, and they flashuntil the driver changes engine speed with theaccelerator pedal or they are deactivated withtheir button.

Foot brake - emergency brake assistance
Emergency brake assistance EBA (Emergency Brake Assist) helps to increase the brakingforce and so reduce the braking distance. EBA detects the driver's braking style and increases the braking force when necessary.The brake force can be reinforced up to thelevel when the ABS system is engaged. TheEBA function is interrupted when the pressureon the brake pedal is reduced.
NOTE
When EBA is activated the brake pedal lowers slightly more than usual, depress(hold) the brake pedal as long as neces-sary. If the brake pedal is released then allbraking ceases.

Fording
Fording means that the car is driven through a water-covered roadway. Fording must be car-ried out with great caution. The car can be driven through water at a maximum depth of 25 cm at a maximumspeed of 10 km/h. Extra caution should beexercised when passing through flowingwater. During driving in water, maintain a low speed and do not stop the car. When the water hasbeen passed, depress the brake pedal lightlyand check that full brake function is achieved.Water and mud for example can make thebrake linings wet resulting in delayed brakefunction. •Clean the electric contacts of the electric engine block heater and trailer couplingafter driving in water and mud.
• Do not let the car stand with water overthe sills for any long period of time - thiscould cause electrical malfunctions.IMPORTANT
Engine damage can occur if water enters the air filter. In depths greater than 25 cm, water could enter the transmission. This reduces thelubricating ability of the oils and shortensthe service life of these systems. In the event of the engine stalling in water, do not try restart - tow the car from thewater to a workshop - an authorised Volvoworkshop is recommended. Risk of enginebreakdown.

Overheating
Under special conditions, for example hard driving in hilly terrain and hot climate, there isa risk that the engine and drive system mayoverheat - in particular with a heavy load. For information about overheating when driv- ing with a trailer, see Driving with a trailer (p.306). • Remove any auxiliary lamps from in front of the grille when driving in hot climates.
• If the temperature in the engine's coolingsystem is too high then a warning symbolis illuminated in the combined instrumentpanel's information display and a text message 
High engine temp Stop safelyis shown there - stop the car in a safe way and allow the engine to run at idlingspeed for several minutes in order to cooldown.
• If the text message 
High engine temp
Stop engine or Coolant level low, Stop
engine is shown then the engine must be
switched off after stopping the car.
• In the event of overheating in the gearbox a built-in protection function is activatedwhich, amongst other things, illuminatesa warning symbol in the combined instru-ment panel, and its display shows the text message 
Transmission hot Reduce
speed or Transmission hot Stop safely- follow the recommendation given and lower the speed and stop the car in a safeway and allow the engine to run at idling

• For lowest fuel consumption, activate ECO (p. 288)* 16
.
• Use the ECO Guide which indicates how fuel-efficiently the car is being driven, seeEco guide & Power guide* (p. 63).
• Drive in the highest gear possible, adap-ted to the current traffic situation androad - lower engine speeds result in lowerfuel consumption. Use the gear indicator(p. 272).
• Avoid sudden unnecessary accelerationand heavy braking.
• High speed results in increased fuel con-sumption - the wind resistance increaseswith speed.
• Do not run the engine to operating tem-perature at idling speed, but rather drivewith a light load as soon as possible - acold engine consumes more fuel than awarm one.
• Drive with the correct air pressure in thetyres and check this regularly - selectECO tyre pressure for best results, seeTyres - approved tyre pressures (p. 407).
• Choice of tyres can affect fuel consump-tion - seek advice on suitable tyres from adealer.
• Remove unnecessary items from the car -the greater the load the higher the con-sumption. •
Use engine braking to slow down, when itcan take place without risk to other roadusers.
• A roof load and ski box increase air resis-tance, leading to higher consumption -remove the load carriers when not in use.
• Avoid driving with open windows.
For information about Volvo Car Corpora- tion's environmental philosophy, see VolvoCars' environmental philosophy (p. 19). For more information about fuel consumption, see Fuel consumption and CO2 emissions (p.403).
WARNING
Never switch off the engine while moving, such as downhill, this deactivates impor-tant systems such as the power steeringand brake servo.

Driving with a trailer
When driving with a trailer there are a number of important points to think about regardinge.g. the towing bracket, the trailer and howthe load is positioned in the trailer. Payload depends on the car's kerb weight. The total of the weight of the passengers andall accessories, e.g. towbar, reduces the car'spayload by a corresponding weight. For moredetailed information on weights, see Weights(p. 390). If the towing bracket is mounted by Volvo, then the car is delivered with the necessaryequipment for driving with a trailer. • The car's towing bracket must be of an approved type.
• If the towbar is retrofitted, check withyour Volvo dealer that the car is fullyequipped for driving with a trailer.
• Distribute the load on the trailer so thatthe weight on the towing bracket com-plies with the specified maximum towballload.
• Increase the tyre pressure to the recom-mended pressure for a full load. For tyrepressure label location, see Tyres - airpressure (p. 328).
• The engine is loaded more heavily thanusual when driving with a trailer.

•
Do not tow a heavy trailer when the car is brand new. Wait until it has been drivenat least 1000 km.
• The brakes are loaded much more thanusual on long and steep downhill slopes.Downshift to a lower gear and adjust yourspeed.
• For safety reasons, the maximum permit-ted speed for the car when coupled witha trailer should not be exceeded. Followthe regulations in force for the permittedspeeds and weights.
• Maintain a low speed when driving with atrailer up long, steep ascents.
• Avoid driving with a trailer on inclines ofmore than 12%.
Trailer cableAn adapter is required if the car's towing bracket has 13 pin electrics and the trailerhas 7 pin electrics. Use an adapter cableapproved by Volvo. Make sure the cable doesnot drag on the ground.

trailer text is shown.
Level control*The rear shock absorbers maintain a constant height irrespective of the car's load (up to themaximum permissible weight). When the caris stationary the rear of the car lowers slightly,which is normal.
Trailer weightsFor information on Volvo's permitted trailerweights, see Towing capacity and towballload (p. 391).
NOTE
The stated maximum permitted trailer weights are those permitted by Volvo.National vehicle regulations can furtherlimit trailer weights and speeds. Towbarscan be certified for higher towing weightsthan the car can actually tow.
WARNING
Follow the stated recommendations for trailer weights. Otherwise, the car andtrailer may be difficult to control in theevent of sudden movement and braking.

Lamp replacement
Lamp replacement can be carried out for bulbs. When replacing LED and Xenon lamps,please refer to a workshop. The bulbs are specified (p. 358). The follow- ing list contains locations of bulbs and otherlight sources that are specialised, such as LED 10
 lamps, or are unsuitable for changing
for some other reason, except at a workshop:
• Active Xenon headlamps - ABL (Xenon lamps)
• Daytime running lights/Position/parkinglamps front
• Side marker lamps front
• Cornering lights
• Side direction indicators, door mirrors
• Approach lighting, door mirrors
• Interior lighting apart from Courtesy light-ing front
• Glovebox lighting
• Position/parking lamps rear/Side markerlamps rear
• Brake light.WARNING
On cars with Xenon headlamps, the replacement of Xenon lamps must be car-ried out at a workshop - an authorisedVolvo workshop is recommended. Workingwith Xenon lamps demands extreme cau-tion because the headlamp is equippedwith a high voltage unit.
WARNING
The car's electrical system must be in key position 
0 for bulb replacement; see Key
positions - functions at different levels (p.70).
IMPORTANT
Never touch the glass part of the bulbs with your fingers. Grease from your fingersis vaporised by the heat, coating thereflector and then causing damage.
NOTE
If an error message remains after the bro- ken bulb has been replaced then we rec-ommend that you visit an authorised Volvoworkshop.
