Gear selector inhibitorThe gear selector inhibitor prevents accidental changing between different gear positions in anautomatic gearbox.
There are two different types of gear selector inhibitor - mechanical and automatic.
Mechanical gear selector inhibitor
The gear selector can be moved forward and back freely between N and D. Other positions are
locked with a latch that is released with the inhib- itor button on the gear selector. With the inhibitor button depressed the lever can be moved forwards or backwards between P, R ,
N and D.
Automatic gear selector inhibitorThe automatic gear selector inhibitor has special safety systems.
From park position - P
To be able to move the gear selector from the P
position, the brake pedal must be depressed and the ignition position must be II.
From neutral position - N
If the gear selector is in the N position and the
car has been stationary for at least 3 seconds (irrespective of whether the engine is running)then the gear selector is locked. To be able to move the gear selector from the N
position to another gear position, the brake pedal must be depressed and the ignition position must be II.
Deactivate automatic gear selector
inhibitor
If the car cannot be driven, e.g. due to a dis- charged battery, the gear selector must be moved to the
N position so that the car can be
moved.
Lift the rubber mat in the compartment in front of the gear selector. Locate the holewith a spring-loaded button in the bottom ofthe compartment.
Press a small screwdriver into the hole and hold.
Move the gear selector to position N and
release the button.
4. Put the rubber mat back in place.

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.
Settings for parking brake
Automatic activation of the parking brake isselected via the centre display. Automatic activation when the car is switched off:1.
Press
Settings in the top view.
2. Press
My CarParking Brake and
Suspension and deselect/select the func-
tion Auto Activate Parking Brake.

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

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.

Economical driving
Drive economically and eco-consciously by driv- ing smoothly, thinking ahead, and adjusting yourdriving style and speed to the prevailing condi-tions.
• For lower fuel consumption, activate ECO drive mode.
• Use the Eco Coast 17
freewheel function -
engine braking will cease and the car'skinetic energy can be used to freewheel forlonger distances.
• Drive in the highest gear 18
possible, adapted
to the current traffic situation and road -lower engine speeds result in lower fuel con-sumption. Use the gear shift indicator.
• Drive at a steady speed and keep a good dis-tance to other vehicles and objects to mini-mise braking.
• High speed results in increased fuel con-sumption - the wind resistance increaseswith speed.
• Do not run the engine to operating tempera-ture at idling speed, but rather drive with anormal load right after starting - a coldengine consumes more fuel than a warmone. •
Drive with the correct air pressure in thetyres and check this regularly - select ECOtyre pressure for best results.
• Choice of tyres can affect fuel consumption -seek advice on suitable tyres from a dealer.
• Remove unnecessary items from the car -the greater the load the higher the consump-tion.
• Use engine braking to slow down, when itcan take place without risk to other roadusers.
• A roof load and space box increase windresistance, leading to higher consumption -remove the load carriers when not in use.
• Avoid driving with open windows.
WARNING
Never switch off the engine while moving, such as downhill, this deactivates importantsystems such as the power steering andbrake servo.

Towing bracket
*
The car can be equipped with a towing bracket that makes it possible to tow e.g. a trailer afterthe car.
There may be different towing bracket variants available for the car; contact a Volvo dealer formore information. For information on towing capacity and towball load, see the section "Towing capacity and tow-ball load".
IMPORTANT
When the engine is switched off, the constant battery voltage to the trailer connector can beswitched off automatically so as not to drainthe starter battery.
IMPORTANT
The towball needs regular cleaning and lubri- cation with grease in order to prevent wear.
