Parking brake The parking brake prevents the car from rolling away from stationary by means of mechanicallylocking/blocking two wheels.
The control for the parking brake is located in the tunnel console between the seats.
A faint electric motor noise can be heard when the electrically-operated parking brake is beingapplied. The noise can also be heard during theautomatic function checking of the parking brake. If the car is stationary when the parking brake is applied then it only acts on the rear wheels. If it isapplied when the car is moving then the normalfoot brake is used, i.e. the brake acts on all fourwheels. Brake function changes over to the rearwheels when the car is almost stationary.

Parking on a hill
WARNING
Always use the parking brake when parking on an inclined surface. Engaging a gear or the automatic transmission's P position is not suf-
ficient to hold the car stationary in all situa- tions.
If the car is parked facing uphill: • Turn the wheels
away from the kerb.
If the car is parked facing downhill:
• Turn the wheels
towards the kerb.
Heavy load uphill
A heavy load, such as a trailer, can cause the car to roll backward when the parking brake isreleased automatically on a steep incline. Avoid this by pulling the control upwards while drivingthe car away. Release the control when theengine achieves traction.

In the event of a fault in the parking brake
Contact an authorised Volvo workshop if it is not possible to release or apply the parking brakeafter several attempts.
An acoustic warning signal sounds when driving with the parking brake applied. If the car has to be parked before a possible fault is rectified then the wheels must be turned as ifparking on a hill and the gear selector must be in position P, or engage first gear if the car has a
manual gearbox.
Low battery voltageIf the battery voltage is too low then the parking brake can neither be released nor applied. Con-nect a donor battery if the battery voltage is toolow.
Replacing the brake liningsThe rear brake linings must be replaced at aworkshop due to the design of the electrically-operated parking brake - an authorised Volvoworkshop is recommended.

Hill start assist
Hill start assist, Hill Start Assist (HSA), prevents the car from rolling backwards when starting onan uphill gradient. When reversing uphill, it pre-vents the car from rolling forwards.
The function means that the pedal pressure in the brake system remains for several secondswhile the driver's foot is moved from brake pedalto accelerator pedal. The temporary braking effect releases after sev- eral seconds or when the driver accelerates. Hill start assist is available even if the function for automatic braking when stationary (Auto hold) isdeactivated.

Automatic braking when stationary
Automatic braking when stationary (Auto Hold) means that the driver can release the brakepedal while maintaining braking effect when thecar has stopped at traffic lights or a junction.
FunctionWhen the car has stopped, the brakes are acti- vated automatically. The function can use eitherfoot brake or parking brake to hold the car sta-tionary and it works on all gradients. When theaccelerator pedal is depressed again, the brakesare released. When braking to a stop on a downhill or uphill gradient - depress the brake pedal a bit harderbefore releasing to ensure that the car does notroll at all. If the driver switches off the engine when the car is stationary, the parking brake is applied.
Automatic deactivation
The function is deactivated automatically: • when the driver's door is open and the driv- er's seatbelt is unfastened.
• in gear position

Driving in water Driving in water means that the car is driven through deep water on a water-covered road-way. Driving in water must be carried out withgreat caution.
The car can be driven through water at a maxi- mum depth of 25 cm at a maximum speed ofwalking pace. Extra caution should be exercisedwhen passing through flowing water. During driving in water, maintain a low speed and do not stop the car. When the water has beenpassed, depress the brake pedal lightly andcheck that full brake function is achieved. Waterand mud for example can make the brake liningswet resulting in delayed brake function.
• If necessary, clean the contacts for the elec-tric heater and trailer coupling after driving inwater and mud.
• Do not let the car stand with water over thesills for any long period of time - this couldcause 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 the lubri-cating ability of the oils and shortens theservice life of these systems. Damage to any component, engine, transmis- sion, turbocharger, differential or its internalcomponents caused by flooding, hydrostaticlocking or oil shortage, is not covered by thewarranty. In the event of the engine stalling in water, do not try restart - tow the car from the water toa workshop - an authorised Volvo workshop isrecommended. Risk of engine breakdown.

Overheating in the engine and drive system
Under special conditions, for example hard driv- ing in hilly terrain and hot climate, there is a riskthat the engine and drive system may overheat -in particular with a heavy load.
• In the event of overheating, the engine's power may be limited temporarily.
• Remove any auxiliary lamps from in front ofthe grille when driving in hot climates.
• If the temperature in the engine's coolingsystem becomes too high then a warningsymbol is illuminated and the driver display shows the message
Engine temperature
High temperature Stop safely. Stop the
car in a safe way and allow the engine to run at idling speed for several minutes and cooldown.
• If the message

shown, stop the car and switch off the engine.
• In the event of overheating in the gearbox, analternative gear shift program will beselected. In addition, a built-in protectionfunction is activated that, amongst otherthings, illuminates a warning symbol and thedriver display shows the message
Transmission warm Reduce speed to
lower temperature or Transmission hot Stop safely, wait for cooling
. Follow the
recommendation given, reduce speed or stop the car in a safe way and allow the engine torun at idling speed for several minutes toenable the gearbox to cool down.
• If the car overheats, the air conditioning maybe switched off temporarily.
• Do not turn the engine off immediately youstop after a hard drive.
NOTE
It is normal for the engine's cooling fan to operate for a time after the engine has beenswitched off.

Overloading the starter battery
The electrical functions in the car load the starter battery to varying degrees. Avoid using the igni-tion position II when the car is switched off.
Instead, use ignition position I - which uses less
power.
Also, be aware of different accessories that load the electrical system. Do not use functions whichuse a lot of power when the car is switched off.Examples of such functions are:
• ventilation fan
• headlamps
• windscreen wiper
• audio system (high volume).
If the starter battery voltage is low, the message
12 V Battery Low charge, will soon enter
power save mode is shown in the driver display.
The energy-saving function then shuts down cer- tain functions or reduces certain functions suchas the ventilation fan and/or audio system.
–In which case, charge the starter battery by starting the car and then running it for atleast 15 minutes - starter battery charging ismore effective during driving than runningthe engine at idling speed while stationary.

Preparations for a long trip
Before a driving holiday or some other type of long journey, it is important to check the car'sfunctions and equipment particularly carefully.
Check that:
• the engine is working normally and that fuel consumption is normal
• there are no leaks (fuel, oil or other fluid)
• all bulbs are working
• the tyres have sufficient tread depth andpressure
• a warning triangle and high-visibility vest arelocated in the car - legally required in certaincountries
• the wiper blades are in good condition.

Winter driving
For winter driving it is important to perform cer- tain checks of the car in order to ensure that itcan be driven safely.
Check the following in particular before the cold season:
• The engine coolant must contain 50% glycol.This mixture protects the engine againstfrost erosion down to approximately –35 °C.To avoid health risks, different types of glycolmust not be mixed.
• The fuel tank must be kept filled to preventcondensation.
• Engine oil viscosity is important. Oils withlower viscosity (thinner oils) facilitate startingin cold weather and also reduce fuel con-sumption while the engine is cold. Readmore about suitable oils in the section"Adverse driving conditions for engine oil".
IMPORTANT
Low viscosity oil must not be used for hard driving or in hot weather.
• The condition of the starter battery and charge level must be inspected. Coldweather places great demands on the starter battery and its capacity is reduced by thecold.
• Use washer fluid with antifreeze to avoid iceforming in the washer fluid reservoir.
Slippery driving conditionsTo achieve optimum roadholding Volvo recom-mends using winter tyres on all wheels if there isa risk of snow or ice.
NOTE
The use of winter tyres is a legal requirement in certain countries. Studded tyres are notpermitted in all countries.
Practise driving on slippery surfaces under con- trolled conditions to learn how the car reacts.

Handling of fuel
Do not use fuel with a lower quality than that rec- ommended by Volvo, as this will negatively affectengine power and fuel consumption.
WARNING
Always avoid inhaling fuel vapour and getting fuel splashes in the eyes. In the event of fuel in the eyes, remove any contact lenses and rinse the eyes in plenty ofwater for at least 15 minutes and seek medi-cal attention. Never swallow fuel. Fuels such as petrol, bioe- thanol and mixtures of them and diesel arehighly toxic and could cause permanent injuryor be fatal if swallowed. Seek medical atten-tion immediately if fuel has been swallowed.
WARNING
Fuel which spills onto the ground can be igni- ted. Switch off the fuel-driven heater before star- ting to refuel. Never carry an activated mobile phone when refuelling. The ring signal could cause sparkbuild-up and ignite petrol fumes, leading tofire and injury.
