Overheating the engine and transmission
In demanding driving conditions, such as when transporting heavy loads, driving in mountainousareas or in very hot weather there is a risk ofoverheating the engine or transmission.
• The engine's output may be slightly limited if there is a risk of overheating.
• Remove e.g., auxiliary lights mounted in frontof the grille in hot weather.
• If the temperature of the engine coolantbecomes too high, the warning symbol will illuminate and the message
Engine
temperature/Stop safely will be displayed.
Stop the vehicle as soon as possible in a safe place and let the engine idle for severalminutes.
• If the message
Engine temperature/High
temperature Turn off engine or Engine
coolant/Stop safely is displayed, stop
safely and turn off the engine.
• If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also by activated, the warning symbol will illuminate and the message
Transmission
warmHigh temperature Reduce speed
or Transmission warmStop safely, wait
for cooling will be displayed in the instru-
ment panel. •
The air conditioning may be switched off temporarily.
• After a prolonged period of driving, do notturn off the engine immediately after stop-ping.
• The engine cooling fan commonly continuesto run for several minutes after the enginehas been turned off.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator) maystart or continue to operate (for up to6 minutes) after the engine has beenswitched off.

2. After refueling, close the fuel filler door by
pressing lightly.
Refueling from a service station pump
To refuel:
1. Open the fuel filler door. Do not refuel with
the engine running 1
2. Insert the pump's nozzle into the fuel filler pipe's opening as far as possible (see the
illustration).
3. Avoid overfilling the fuel tank. Do not press the handle on the filler nozzle after it has stopped pumping. Too much fuel in the tankin hot weather conditions can cause the fuelto overflow. Overfilling could also cause dam-age to the emission control systems.
CAUTION
Avoid spilling gasoline during refueling. In addition to causing damage to the environ-ment, gasolines containing alcohol can causedamage to painted surfaces, which may notbe covered under the New Vehicle LimitedWarranty.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
• Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
• Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
• Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components

To start the engine.
1. A remote key must be in the passenger com-
partment. On models with the standard Passive Start, the key has to be in the frontsection of the passenger compartment. If thevehicle is equipped the optional PassiveEntry system (keyless locking/unlocking) thekey can be anywhere in the vehicle.
2. Press firmly on the brake pedal 2
.
3. Turn the start knob toward START and
release it to start the engine.
> The starter motor will crank until the engine starts or its overheating protection is triggered.
WARNING
• Never use more than one floor mat at a time on the driver's floor. Before driving,remove the original mat from the driver'sseat floor before using any other type offloor mat. Any mat used in this positionshould be securely and properly anchoredin the attaching pins. An extra mat on thedriver's floor can cause the acceleratorand/or brake pedal to catch. Check thatthe movement of these pedals is notimpeded.
• Volvo's floor mats are specially manufac-tured for your car. They must be firmlysecured in the clips on the floor so thatthey cannot slide and become trappedunder the pedals on the driver's side.
During normal starts, the electric motor is priori-tized and the gasoline engine will not start. Thismeans that when the start knob has been turned toward START and released, the electric motor is
activated ("started") and the vehicle is ready to be driven. The warning and information symbolsin the instrument panel will go out and thechosen theme will be displayed to indicate thatthe electric motor has been activated. However, in certain situations, such as in coldweather or if the hybrid battery is not sufficientlycharged, the gasoline engine will start instead. The vehicle should not be started if the charging cable is connected.
However, if the
cable cannot be disconnected or if the vehicleincorrectly detects a cable that is not connected,the vehicle can be started using an override pro-cedure:
1. Press the brake pedal and turn the start
knob to START.
2.
Remove charge cable to start will appear
in the instrument panel.
3. Turn the start knob to START again.
4.
Charge cable removed? Press start button 7s to start will be displayed. Turn
the start knob to START again and hold it for
7 seconds to start the vehicle.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
2 If the vehicle is moving, it is only necessary to turn the start knob toward START to start the engine.

Back-up reader in the tunnel console
If Vehicle key not found is displayed in the
instrument panel, place the remote key in the back-up reader in the tunnel console (see theillustration) and try again to start the engine.
NOTE
When the remote key is in the back-up reader, be sure there are no other metallicobjects (e.g., other keys, coins, cell phones) inthe cup holder. This could affect the back-upreader's function.
If Vehicle start System check, wait is dis-
played in the instrument panel when you try to start the vehicle, wait until the message is nolonger displayed and try to start again.
CAUTION
If the engine does not start after the third try, wait for approximately 3 minutes before tryingto start it again to give the battery time torecover its starting capacity.
WARNING
• Always remove the remote key from the passenger compartment when leaving thevehicle and ensure that the ignition in mode
0.
• On vehicles with the optional Passive Entry, never remove the remote key fromthe vehicle while it is being driven ortowed.
• Always place the gear selector in Parkand apply the parking brake before leav-ing the vehicle. Never leave the vehicleunattended with the engine running.
• Always open garage doors fully beforestarting the engine inside a garage toensure adequate ventilation. The exhaustgases contain carbon monoxide, which isinvisible and odorless but very poisonous.
NOTE
After a cold start, idle speed may be noticea- bly higher than normal for a short period. Thisis done to help bring components in theemission control system to their normal oper-ating temperature as quickly as possible,which enables them to control emissions andhelp reduce the vehicle's impact on the envi-ronment.
CAUTION
•
When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
• Selecting
P or N when idling at a stand-
still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.

Preparations for charging the hybrid batterySeveral preparatory steps should be taken before starting to charge the hybrid battery.WARNING
• The charging cable must be grounded when in use. It is equipped with a cordwith a grounding conductor and agrounding plug. The plug must beinserted into an appropriate outlet that isproperly installed and grounded inaccordance with all local codes and ordi-nances and is not damaged in any way
• Children should be supervised when inthe vicinity of the charging cable when itis plugged in
• High voltage is present in your electricmeter housing and power distributionservice panel. Contact with high voltagecan cause death or serious personalinjury
• Do not use the charging cable if it isdamaged in any way
• Always position the charging cable sothat it will not be driven over, stepped on,tripped over or otherwise damaged, orcause personal injury
• Disconnect the charger from the wall out-let before cleaning it
• Never connect the charging cable to anextension cord or a multiple plug socket
• If the hybrid battery needs to be replaced, this may only be done by Volvo retailer orauthorized Volvo workshop
Also, refer to the manufacturer's instructions for using the charging cable and its compo-nents.
Prior to chargingThe charging cable and any of its components should not be wet or submerged in any liquid. The charge module or its plug should not be exposed to direct sunlight. This could cause theunit's overheating protector to reduce or stop thehybrid battery charging process. Be sure the 120-/240-volt socket used has ade- quate current for charging electrically poweredvehicles. Have the socket checked by an licensedelectrician if you are uncertain.

CAUTION
Never disconnect the charging cable from the 120-/240-volt socket while charging is inprogress. This could damage the socket. Always stop the charging process (by unlock- ing the vehicle) and disconnect the chargingcable from the vehicle's charging socket before disconnecting the other end from the
120-/240-volt socket being used.
During the charging process, condensation may form under the vehicle, which is normal and iscaused by cooling the hybrid battery.

Charging the hybrid battery In addition to the conventional fuel tank, Twin Engine Plug-in Hybrid vehicles are also equip-ped with a rechargeable lithium-ion hybrid bat-tery.
The hybrid battery is recharged using a charging cable located in a storage compartment underthe floor of the cargo area. See also the article"Charging cable."
WARNING
The hybrid electrical system in your vehicle uses high voltage electrical current. Any dam-age to this system or to the hybrid batterymay result in the danger of overheating, fire,or serious injury. If the vehicle is involved in acollision or is subjected to flooding, fires, etc.,have it inspected by a trained and qualifiedVolvo service technician. Prior to this inspec-tion, the vehicle should be parked outdoors ata safe distance from any building or poten-tially flammable materials.
The hybrid battery's charging time depends on the charging current used.
NOTE
The capacity of the hybrid battery diminishes somewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.
Charging is indicated in three ways: • Charge module (the unit that is plugged into the wall socket): The blue indicator light onthe cable's charge module will flash red sev-eral times when the unit is plugged into awall socket while a safety check is being per-formed and will then glow steadily blue toindicate that the charger is ready to use.
• A green indicator light in the vehicle's charg-ing socket will flash green while the batteryis charging and will glow steadily green whenthe hybrid battery is fully charged. The blueindicator light in the charge module will alsoflash while charging is underway and willglow steadily blue when charging is comple-ted.
• A gauge in the instrument panel will alsoindicate the battery's charge level.
The hybrid battery charging process also chargesthe vehicle's start battery. If the hybrid battery's temperature is below – 13 ºF (–10 ºC) or above +104 ºF (+40 ºC), some
of the vehicle's functions may be reduced or not

Loading specifications Properly loading your vehicle will provide maxi- mum return of vehicle design performance.
Weight designations
Before loading your vehicle, familiarize yourself with the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
Permissible axle weight
The maximum allowable weight that can be car- ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load Limit
1. Locate the statement "the combined weightof occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driver and passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.
WARNING
• Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.
