Towing using a towline
This section refers to one vehicle being towedbehind another using a towline.
Twin Engine vehicles may not be towed behindanother vehicle due to the risk of damage to theelectric motor. The vehicle must be lifted onto atow truck and transported with all four wheels onthe bed or lifting platform of the truck (no wheelsmay touch the road).
Towing another vehicle
Towing another vehicle requires a lot of power -use the AWD drive mode. This helps charge thehybrid battery and improve the vehicle's drivingand roadholding characteristics.
Before towing another vehicle, check applicablespeed limit regulations.

Jump starting
Do 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.

CAUTION
Attempts to tow-start the vehicle could causedamage to the electrical drive motor andthree-way catalytic converter.

Using the electrical outlets
The 12 V outlet can be used for devicesintended for this such as MP3 players, coolersand cellular phones.
The ignition must be in at least mode I for theoutlets to supply current. The outlets will then beactive as long as there is sufficient charge in thestart battery.
If the engine is turned off and the vehicle islocked, 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 outletswhen 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 orheavy 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.

Using 12 V outlets
1. Remove the stopper (tunnel console) or folddown the cover (trunk/cargo compartment)over the socket and plug in the device.
2. Unplug the device and put the stopper backin (tunnel console) or fold up the cover(trunk/cargo compartment) when the socketis not in use or left unattended.

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 System
OBD II is part of your vehicle's computerizedengine 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 avehicle'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 inspectionfor 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 waslit 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 maintenance
Periodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet.
The following points can be carried out betweenthe 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. Inspectthe 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, toreduce 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 atthe 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 servicetechnician can connect your vehicle to the work-shop's Wi-Fi network to perform troubleshootingand download software. For this type of commu-nication, the vehicle only connects to a work-shop's network. It is not possible to connect thevehicle to another Wi-Fi network (e.g. your homenetwork) in the same way as to a workshop's net-work.

Connecting with remote key
Connection is usually managed by the servicetechnician, who will use the remote key buttons. Itis therefore important to bring a key with buttonswith you when you visit the workshop. Pressingthe lock button on the remote key three times willconnect the vehicle to the workshop's Wi-Fi net-work.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.

Start battery
The vehicle has a single-pole electrical systemthat uses the chassis and engine mount as con-ductors.
The start battery is used to start the electricalsystem and power electrical equipment in thevehicle. The hybrid battery is used to start thecombustion engine.
The start battery should only be replaced by a
workshop15.
The start battery is a 12 V AGM (Absorbed GlassMat) battery, dimensioned for regenerative charg-ing and to support the function of the vehicle'svarious systems.
The service life and performance of the start bat-tery are affected by factors such as driving style,driving conditions, climate, battery discharges,number of starts, etc.
Never disconnect the start battery while theengine is running.
Make sure the cables to the start battery arecorrectly connected and the clamps aresecurely tightened.

WARNING
Batteries generate hydrogen gas, whichis flammable and explosive.
Do not connect the jumper cable to anypart of the fuel system or to any movingparts. Avoid touching hot manifolds.
Battery fluid contains sulfuric acid. Do notallow battery fluid to contact eyes, skin,fabrics or painted surfaces.
If contact occurs, flush the affected areaimmediately with water. Obtain medicalhelp immediately if eyes are affected.
Never expose the battery to open flameor electric spark. Do not smoke near thebattery. Failure to follow the instructionsfor jump starting can lead to injury.

CAUTION
It is not possible to charge another vehicle'sbattery by means of current through thecharging points. Using the charging points tocharge another vehicle's battery could causea fuse to blow, which would cause the charg-ing points to stop working.

CAUTION
Only a modern battery charger with controlledcharge voltage should be used to charge thestarter battery. The rapid charging functionshould not be used as this could damage thebattery.

NOTE
If both the starter battery and the hybrid bat-tery are discharged, both batteries must becharged. In such cases, it is not possible tocharge only the hybrid battery first.
The starter battery must have a certain levelof charge for it to be possible to charge thehybrid battery.
CAUTION
Failure to observe the following could causethe infotainment energy save mode to tempo-rarily stop working and/or a message in thedriver's display regarding the state of chargeof the starter battery may be temporarilyincorrect after an external starter battery orbattery charger has been connected:
The negative battery terminal of the vehi-cle's starter battery must never be usedto connect an external starter battery orbattery charger – only the vehicle's neg-ative charging point should be used asa grounding point.
NOTE
If the starter battery becomes discharged toomany times, it will shorten its service life.
The service life of the starter battery is affec-ted by several factors, such as driving condi-tions and climate. The starting capacity of thebattery reduces gradually over time. The bat-tery must therefore be recharged if the vehi-cle is not used or a long period of time or if itis only driven short distances. Severe cold fur-ther limits the starting capacity.
To keep the starter battery in a good condi-tion, the vehicle should be driven at least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging.
A starter battery that is always kept fullycharged has the maximum service life.
