Preconditioning
Preconditioning the vehicle before driving can help reduce wear and reduce energy consump-tion during a trip.
Preconditioning can be started immediately or started at a preset time using a timer. The function utilizes several of the vehicle's sys- tems:
• In cold weather, the high-voltage coolantheater (HVCH) heats the passenger com-partment to a comfortable temperature.
• In warm weather, air conditioning cools thepassenger compartment to a comfortabletemperature.
• The electrically heated steering wheel
* and
seats * can be activated.
• Heating for the windshield, rear window anddoor mirrors are automatically activated asneeded.
During preconditioning in a hot climate, conden-sation from the air conditions may drip under thevehicle. This is normal.
NOTE
Preconditioning is only available when the car is connected to an electrical outlet. A charg-ing post that is not always active, for examplebecause of a timer, can cause loss of functionfor preconditioning. If the car is not connected to an electrical socket it is still possible in a warm climate toachieve brief cooling of the passenger com-partment by direct starting preconditioning.
NOTE
During preconditioning of the passenger compartment, the vehicle works to reach acomfortable temperature and not the tem-perature set in the climate system.

Overheating of engine andtransmission
In demanding driving conditions, such as driving in mountainous areas or hot weather, there is arisk of the engine or transmission overheating,especially when carrying heavy loads.
• Engine power may be temporarily limited.
• Remove any auxiliary lights mounted in front of the grille when driving in hot weather.
• If the temperature in the engine's coolingsystem becomes too high, a warning symbolwill appear in the instrument panel along with the message
Engine temperature High
temperature Stop safely. Pull over to a
safe location and let the engine idle for a few minutes to cool down.
• If the message
Engine temperature High
temperature Turn off engine or Engine
coolant Level low, turn off engine is dis-
played, stop the vehicle and turn off the engine.
• If the transmission begins to overheat, analternative gear shifting program will beselected. An integrated protective functionwill also be activated, the warning symbol will illuminate and the message
Transmission
warm Reduce speed to lower
temperature or Transmission hot Stop
safely, wait for cooling will be displayed in
the instrument panel. Follow the recommen- dations given by reducing speed or stopping the vehicle safely and letting the engine idle for a few minutes to let the transmissioncool.
• If the vehicle begins to overheat, the air con-ditioning may be temporarily switched off.
• After a prolonged period of driving indemanding conditions, do not turn off theengine immediately after stopping.
NOTE
It is normal for the engine's cooling fan to operate for a short time after the engine isswitched off.

NOTE
If the conditions for measuring oil level are not properly fulfilled (time after engine shut-down, vehicle inclination, ambient tempera- ture, etc.) the message
No value availablewill be shown in the center display. This does not mean that anything is wrong in the vehi-
cle systems.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions on the package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.
Coolant expansion tank, left-hand drive vehicle.

MAINTENANCE AND SERVICE
* Option/accessory.603
Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fill coolant as needed. The level should not exceed the yellow MAX mark inside the
expansion tank.
Put the components back in place in the reverse order.
CAUTION
• Mix the coolant with water of acceptable quality. If you are unsure of the quality ofthe water, use a Volvo-recommendedpremixed coolant.
• Make sure the coolant mixture is 50%water and 50% coolant.
• Only use coolants with corrosion protec-tion recommended by Volvo.
• To help ensure sufficient corrosion pro-tection in the system, only use new cool-ant when replacing larger components inthe cooling system.
• Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
• High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.

Replacing bulbs
Halogen headlights are not available on all mod- els and markets. Contact a Volvo retailer formore information. LED 13
bulbs must be replaced by a workshop.
An authorized Volvo workshop is recommended.
NOTE
For information on lights not mentioned in this article, contact a Volvo dealer or a certi-fied Volvo service technician.
NOTE
Exterior lighting such as headlights and tail- lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
NOTE
Bulbs for active curve lighting * contain traces
of mercury and should therefore always be submitted to a certified Volvo service techni-cian.
