The ventilation system consists of fans in the seats and backrests that draw air through theseat upholstery. The cooling effect increases thecooler the passenger compartment air becomes.The system can be activated when the engine isrunning and takes seat temperature, solar radia-tion and outside temperature into consideration.

STARTING AND DRIVING

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.

MAINTENANCE AND SERVICE

Coolant expansion tank, right-hand drive car.
Grip the hatch's handle and lift/jiggle the hatch from the plastic cover.
Screw off the cap on the expansion tank and top up with coolant. The coolant level must not exceed the yellow MAX mark inside the
expansion tank.
Reinstall the parts in reverse order. If there is coolant under the car, if there is cool- ant smoke, or if more than 2 litres have beenfilled, always call for recovery to avoid the risk ofengine damage due to a defective cooling sys-tem when attempting to start the car.
IMPORTANT
• A high content of chlorine, chlorides and other salts may cause corrosion in thecooling system.
• Always use coolant with anti-corrosionagent as recommended by Volvo.
• Ensure that the coolant mixture is 50%water and 50% coolant.
• Mix the coolant with approved quality tapwater. In the event of any doubt aboutwater quality, used ready-mixed coolant inaccordance with Volvo recommendations.
• When changing coolant/replacing cool-ing system components, flush the coolingsystem clean with approved quality tapwater or flush with ready-mixed coolant.
• The engine must only be run with a well-filled cooling system. Otherwise, tempera-tures that are too high may occur result-ing in the risk of damage (cracks) in thecylinder head.
