* Option/accessory.207
The function utilises several systems in different cases: •
Residual heat from the engine, in a cold cli- mate, heats the passenger compartment tocomfort temperature.
• The ventilation, in a hot climate, cools thepassenger compartment to the current outertemperature.
NOTE
Climate comfort retention is switched off when the car is locked from the outside toavoid using residual heat unnecessarily. Useof the function is intended to maintain climatecomfort when driver or passengers remaininside the car.

Parking heater *
The parking heater helps the passenger com- partment reach the correct temperature beforedriving.
The parking heater is one of two subfunctions of the car's heater. The heater is fitted in the frontright-hand wheel housing.
NOTE
When the heater is running, smoke may be emitted from the right-hand front wheel hous-ing and a low hum may be heard. A tickingsound from the fuel pump may also be heardfrom the rear section of the car. This is per-fectly normal.
The parking heater starts automatically when extra heat is required if the parking climate con- trol's preconditioning * is activated.
It is then switched off automatically when the right temperature, the time of a set timer or theheater's maximum running time has beenreached. The heater's maximum running time is 40 minutes.
NOTE
Make sure there is enough fuel in the car's normal fuel tank if the heater needs to beused. Make sure that there is enough charge in the starter battery if the heater needs to be used.
IMPORTANT
Repeated use of the parking heater combined with short journeys may discharge the batteryand impair starting. If the heater is used on a regular basis, then the car should be driven for the same amountof time that the heater is used in order toensure that the car's battery is recharged withthe same amount of energy as consumed bythe parking heater. The parking heater is usedfor a maximum of 40 minutes each time.
WARNING
Do not use preconditioning if the car is equip- ped with a heater *:
• In unventilated spaces indoors. Exhaust gases are emitted if the heater starts.
• In locations with combustible or flamma-ble material nearby. Fuel, gas, long grass,sawdust, etc. may ignite.

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.
