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.

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
• blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Put the ignition in mode 0.
2. Make sure the auxiliary battery (the battery used to jump start the discharged battery) has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and make surethat the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliary battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to prevent short circuits with other components in theengine compartment.
5. Fold back the cover over your vehicle's posi- tive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start termi- nal (2).
7. Clamp the black jumper cable onto the auxili- ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securely attached to help prevent sparks while jumpstarting. 10. Start the engine of the assisting vehicle and
let it run for a few minutes at a higher idlingspeed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the engine does not start, allow an additional 10minutes of charging time and then try to startthe engine again.
NOTE
When the engine is started under normal conditions, the vehicle's electrical drive motoris prioritized – the gasoline engine remainsoff. This means that the electric motor has"started" and the vehicle is ready to be drivenonce the start knob has been turned clock-wise. Start of the electric motor is indicatedby the indicator lights on the instrument panelgoing out and its preselected theme illuminat-ing.
CAUTION
Do not touch the connections between the cable and the vehicle during the start attempt.Risk of sparking.
12. Remove the jumper cables in the reverse
order ‒ first the black cables and then the
red cables. Make sure that none of the clamps of the black jumper cables come into contact witheither vehicle's positive (+) jump start termi-nals or either of the red jumper cable's con-nected clamps.

Towing using a towlineThis section refers to one vehicle being towed behind another using a towline.
Twin Engine vehicles may not be towed behind another vehicle due to the risk of damage to theelectric motor. If the vehicle cannot be driven andneeds to be moved, it must be transported on atow truck with all four wheels on the bed of thetruck.
Towing another vehicleTowing another vehicle requires a lot of power - use the AWD drive mode. This helps charge the
hybrid battery and improve the vehicle's driving and roadholding characteristics. Before towing another vehicle, check applicable speed limit regulations.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.

intended for this, such as chargers, laptops, etc.
The ignition must be in at least mode I for the
outlets to supply current. The outlets will then be active as long as there is sufficient charge in thestart battery. If the engine is turned off and the vehicle is locked, the outlets will be deactivated. If theengine is turned off and the vehicle remainsunlocked, the sockets will remain active for up to7 minutes.
NOTE
Bear in mind that using the electrical outlets when the engine is off could cause the starterbattery to have too low of a charge level,which could limit other functionality. Accessories connected to the electrical out- lets can be activated even when the vehicleelectrical system is off or if preconditioning isused. For this reason, disconnect plugs whenthey are not in use to prevent the starter bat-tery from becoming discharged.
WARNING
• Do not use accessories with large or heavy plugs – they could damage the out-let or come loose while you are driving.
• Do not use accessories that could causedisruptions to e.g. the vehicle's radioreceiver or electrical system.
• Position the accessory so that there is norisk of it injuring the driver or passengersin the event of heavy braking or a colli-sion.
• Pay attention to connected accessoriesas they can generate heat that could burnpassengers or the interior.

Periodic maintenance helps minimize
emissions
NOTE
•Refer to your Service and Warranty Book- let for a comprehensive service and main-tenance schedule up to 240,000 km(150,000 miles). This program containsinspections and services necessary forthe proper function of your vehicle andincludes components that affect vehicleemissions.
• The Warranty and Service Records Infor-mation booklet also contains detailedinformation concerning the warrantiesthat apply to your vehicle.
On-board Diagnostic SystemOBD II is part of your vehicle's computerized engine management system. It stores diagnosticinformation about your vehicle's emission con-trols. It can light the Check Engine light (MIL) if itdetects an emission control "fault." A "fault" is acomponent or system that is not performingwithin an expected range. A fault may be perma-nent or temporary. OBD II will store a messageabout any fault.
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.

Data transfer between vehicle andworkshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net- work for secure data transfer between your vehi-cle and the workshop. Your visit to the workshopwill be easier and more effective when diagnos-tics information and software can be transferredover the workshop's network.
When you arrive at the workshop, your technician can connect your vehicle to the workshop's Wi-Finetwork to perform troubleshooting and down-load software. For this type of communication,the vehicle only connects to the workshop's net-work. The vehicle can only be connected to thedesignated workshop networks, not to any othernetwork, e.g. your home network.
Manual connection to workshop Wi-FiManual connection is usually performed by aservice technician. Because the technician usesthe buttons on your remote key to connect thevehicle, it is important that you bring a key withbuttons when taking the vehicle in to a workshop.Pressing the lock button on the remote key threetimes will connect the vehicle to the workshop'sWi-Fi network. When the car is connected to a Wi-Fi network, the
