300 front starts moving again then the adaptive cruise control is set in standby mode with automaticbraking.
–The Adaptive Cruise Control is reactivated in one of the following ways:
• Press the steering wheel button
.
• Depress the accelerator pedal.
> The Adaptive Cruise Control resumes fol- lowing the vehicle ahead if it starts mov- ing forward within 6 seconds.
NOTE
ACC can keep the car stationary for a maxi- mum of 5 minutes. After this the parkingbrake is applied and adaptive cruise control isdisengaged. The parking brake must be released before the adaptive cruise control can be reactivated.
Cessation of automatic braking
In some situations, automatic braking ceases on reaching 0 km/h and Adaptive Cruise Control isset in standby mode. This means that the brakesare released and the car may start to roll - thedriver must therefore intervene and brake the carhimself/herself to keep it stationary. This may take place in the following situations:
• the driver puts his/her foot on the brakepedal
• the parking brake is applied
• the gear selector is moved to
P, N , or R posi-
tion
• the driver sets the adaptive cruise control inthe standby mode.
Automatic activation of parking brakeIn certain situations the parking brake is appliedto keep the car stationary. This takes place if the adaptive cruise control is holding the car stationary with the foot brake and: •the driver opens the door or takes off his/her seatbelt
• ACC has kept the car stationary for morethan approx. 5 minutes
• the brakes have overheated
• the engine is switched off.

Limitations of the adaptive cruise control *
The (Adaptive Cruise Control - ACC) may have limitations in certain situations.
Steep roads and/or heavy loadBear in mind that the adaptive cruise control is primarily intended for use when driving on levelroad surfaces. The function may have difficulty inkeeping the correct distance from the vehicleahead when driving on steep downhill slopes - inwhich case, be extra attentive and ready to brake.Do not use the adaptive cruise control with aheavy load or with a trailer connected to the car.
Miscellaneous
• Drive mode Off Road cannot be selected
when the adaptive cruise control is activated.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Cessation of automatic braking
In some situations, automatic braking ceases on coming to a standstill and Pilot Assist is set instandby mode. This means that the brakes arereleased and the car may start to roll - the drivermust therefore intervene and brake the car him-self/herself to keep it stationary. This may take place in the following situations:
• the driver puts his/her foot on the brake pedal
• the parking brake is applied
• the gear selector is moved to
P, N , or R posi-
tion
• the driver sets Pilot Assist in the standbymode.
Automatic activation of parking brakeIn certain situations the parking brake is appliedto keep the car stationary. This takes place if Pilot Assist is holding the car stationary with the foot brake and: •
the driver opens the door or takes off his/her seatbelt
• Pilot Assist has kept the car stationary formore than approx. 5 minutes
• the brakes have overheated
• the engine is switched off.

Gear positions for automatic gearbox
With an automatic gearbox, the system chooses the gear so that driving is optimal. The gearboxalso has a manual gearshift mode.
Gear positions in the driver display
The driver display shows the gear selector's posi- tion:
P, R, N, D or M.
In manual gearshift mode, the gear being used is also shown.
Gear positions
Park position - P
Select the P position when the car is parked or
when starting the engine. The car must be sta- tionary when the park position is selected. To be able to move the gear selector from thepark position, the brake pedal must be depressed and the ignition position must be
II.
The gearbox is mechanically blocked when the P
position is engaged. Apply the parking brake first when the car is parked.
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.
NOTE
The gear selector must be in P position to
allow the car to be locked and alarmed.
Reverse position - R
Select position R to reverse. The car must be sta-
tionary when reverse position is selected.
Neutral position - N
No gear is engaged and the engine can be started. Apply the parking brake if the car is sta- tionary with the gear selector in N position.
To be able to change from the neutral position to another gear position, the brake pedal must be depressed and the ignition position must be II.

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 (p. 412)
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

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
Engine temperature High
temperature Turn off engine or Engine
coolant Level low, turn off engine is
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.

Driving with a trailer under special conditions
When driving with a trailer in hilly terrain in a hot climate there may be a risk of overheating.
In the event of overheating, a warning symbol illu- minates in the driver display together with a mes-sage, see section "Overheating in the engine anddrive system". The following only applies to cars with automatic gearbox. The automatic gearbox selects the optimum gear related to load and engine speed.
Steep inclinesDo not lock the automatic gearbox in a highergear than the engine "can cope with" - it is notalways a good idea to drive at a high gear withlow engine speed.
Parking on a hill1. Depress the brake pedal fully.
2. Activate the parking brake.3. Select gear position P.
4. Release the brake pedal.Block the wheels with chocks when parking a car with hitched trailer on a hill.
