Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to make sure it can bedriven safely.
Before the cold season arrives:
• Make sure the engine coolant contains 50% antifreeze. This mixture helps protect theengine from frost erosion down toapprox. -35 °C (-31 °F). Do not mix differenttypes of antifreeze as this could pose ahealth risk.
• Keep the fuel tank well filled to prevent con-densation from forming.
• Check the viscosity of the engine oil. Oil withlow viscosity (thinner oil) improves cold-weather starting and reduces fuel consump-tion when driving with a cold engine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
•
Check the condition and charge level of the start battery. Cold weather places greaterdemands on the start battery and reduces itscapacity.
• Use washer fluid containing antifreeze tohelp prevent ice from forming in the washerfluid reservoir.
Slippery driving conditionsFor optimal traction and roadholding, Volvo rec-ommends using snow tires on all wheels when-ever there is a risk of snow or ice on the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under con- trolled conditions to learn how the vehicle reacts.

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.

Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can thenread "faults." In some states, this type of inspec-tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons:
• If your Check Engine (MIL) light is lit, yourvehicle may fail inspection.
• If your vehicle's Check Engine light was lit,but went out without any action on your part,OBD II will still have a recorded fault. Yourvehicle may pass or fail, depending on theinspection practices in your area.
• If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit - or was lit but went out without service, have your vehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, a periodof driving is necessary to bring the OBD IIsystem to "ready" for inspection. Two half-hour trips of mixed stop-and-go/highwaydriving are typically needed to allow OBD II toreach readiness. Your Volvo retailer can pro-vide you with more information on planning atrip.
• Maintain your vehicle in accordance with yourvehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet. The following points can be carried out between the normally scheduled maintenance services.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
• Check cold tire pressure in all tires. Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min" and"max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with a softcloth.
• Visually inspect battery terminals for corro-sion. Corrosion may indicate a loose terminalconnector, or a battery near the end of itsuseful service life. Consult your Volvo retailerfor additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup ofdirt, and corrosion that can be caused by salt res-idues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other placeswhere they may collect.

Engine compartment overview
This overview shows some service-related com- ponents.
The layout of the engine compartment may vary depend- ing on model and engine variant.

WARNING
Bear in mind that the cooling fan (located at the front of the engine compartment behindthe radiator) may start or continue runningautomatically up to about 6 minutes after theengine is turned off. Always entrust engine washing to a workshop – an authorized Volvo workshop is recom-mended. If the engine is hot, there is a risk offire.
WARNING
The ignition system works with extremely high and dangerous voltages. The vehicle electrical system should always be in ignition mode
0
when work in being performed in the engine compartment. Do not touch any spark plugs or ignition coils when the vehicle electrical system is in igni- tion mode II or when the engine is warm.

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.
