Limited field of vision
The radar sensor has a limited field of vision. Insome situations, it may detect a vehicle later thanexpected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles veryclose to your vehicle may be delayed in cer-tain situations, e.g. if a vehicle pulls in
between your vehicle and the vehicle directlyahead.
Small vehicles, such as motorcycles, or vehi-cles that are not driving in the center of thelane may remain undetected.
In curves, the radar may detect the wrongvehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossi-ble for the radar to detect. The driver should beextra alert when driving behind vehicles towinglow trailers when Adaptive Cruise Control or PilotAssist is activated.
Camera
Reduced visibility
Cameras have the same limitations as the humaneye. In other words, their “vision" is impaired byadverse weather conditions such as heavy snow-fall/rain, dense fog, swirling dust/snow, etc.These conditions may reduce the function of sys-
tems that depend on the camera or cause thesesystems to temporarily stop functioning.
Strong sunlight, reflections from the road surface,ice or snow covering the road, a dirty road sur-face, or unclear lane marker lines may drasticallyreduce the camera
HYBRID INFORMATION

General information about TwinEngine
Twin Engine vehicles are driven just like anyother vehicle, but certain functions differ from avehicle powered exclusively by gasoline. Theelectric motor powers the vehicle primarily at lowspeeds; the gasoline engine is used at higherspeeds or during more active driving.
The instrument panel displays Twin Engine-spe-cific information - charging information, selecteddrive mode, distance to discharged battery andhybrid battery charge level.
Different drive modes can be selected while driv-ing, e.g. electric power only or, if more power isneeded, a combination of electric and gasolinepower. The vehicle calculates the optimal combi-nation of driveability, driving experience, environ-mental impact and fuel economy for the selecteddrive mode.
In order to function optimally, the hybrid battery(and its electrical drive systems) and the gasolineengine (and its drive systems) must be at thecorrect operating temperature. Battery capacitycan be considerably reduced if the battery is toocold or too hot. Preconditioning prepares thevehicle's drive systems and passenger compart-ment before driving to help reduce both wear andenergy consumption. It also helps increase thehybrid battery's range.
The hybrid battery which powers the electricmotor is recharged using the charging cable. It
can also be recharged during light braking andthrough engine braking in gear position B. Thecombustion engine can also help recharge thehybrid battery.
Important
No electrical current
Keep in mind that if there is no electrical currentto the vehicle, i.e. the ignition is switched off orthe start battery is discharged, certain functionssuch as brakes, power steering, etc. will not work.
WARNING
If the vehicle does not have electrical currentand both the electric motor and the gasolineengine are switched off, the brakes cannot beused to stop the vehicle.
Towing not permitted
Never tow a Twin Engine vehicle behind anothervehicle, as this could damage the electric motor.
Exterior engine noise
WARNING
Please be aware that there is no sound fromthe engine when the vehicle is being poweredby the electric motor and it may be difficult todetect by children, pedestrians, cyclists andanimals. This is especially true at low speeds.
High-voltage electrical current
WARNING
A number of electrical components in TwinEngine Plug-in Hybrid vehicles use high-volt-age current and can be extremely dangerousif handled incorrectly. These components andany orange wiring in the vehicle may only behandled by trained and qualified Volvo servicetechnicians.
Do not touch anything that is not clearly descri-bed in this Owner's Manual.

STARTING AND DRIVING
414
This drive mode is optimized for maximum drivingdistance with electric propulsion and is primarilyintended for use in city driving. Pure helps pro-vide the lowest possible consumption even whenthe hybrid battery is fully discharged. ECO climateis activated to control the climate in the passen-ger compartment, and in slippery road conditionsslightly more wheel spin may be permitted beforeall-wheel drive is automatically activated.
ECO Climate
In Pure mode, ECO climate is automatically acti-vated in the passenger compartment to helpreduce energy consumption.
NOTE
When the Pure drive mode is activated, set-tings for certain climate system and electricityconsuming functions are reduced. Some ofthese settings can be reset manually, but fullfunctionality will only be restored by leavingPure mode or adapting the Individual drivemode to full climate system functionality.
If condensation forms on the windows, tap themax defroster button, which will function normally.
Constant AWD
Improves the vehicle's traction and handlingby increasing all-wheel drive.
This drive mode locks the vehicle in all-wheeldrive. An optimal distribution between front andrear axle torque helps provide the best possible
control, stability and traction, e.g. on slipperyroads or when towing a heavy trailer or anothervehicle. The Constant AWD drive mode isalways available regardless of the hybrid battery'scharge status.
Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption.
In the other drive modes, the vehicle automati-cally adapts the need for all-wheel drive accord-ing to the road surface, and can activate the elec-tric motor or start the combustion engine as nee-ded.
Power
The vehicle gets sportier driving characteris-tics and a faster acceleration response.
This drive mode maximizes the combined powerfrom the combustion engine and the electricmotor by providing power to both the front andrear wheels. Gear shifting will be faster and moredistinct and the transmission will prioritize gearswith a higher traction force. Steering response isfaster and suspension is stiffer.
Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption.
This drive mode is optimized for maximum per-formance and throttle response. It changes thethrottle response, gear shifting program andturbo boost system. Chassis settings and steer-ing and brake response are also optimized. The
Power drive mode is always available regardlessof the hybrid battery's charge status.

Use of Additives
With the exception of gas line antifreeze duringwinter months, do not add solvents, thickeners, orother store-bought additives to your vehicle'sfuel, cooling, or lubricating systems. Overuse maydamage your engine, and some of these additivescontain organically volatile chemicals. Do notneedlessly expose yourself to these chemicals.
WARNING
Never carry a cell phone that is switched onwhile refueling your vehicle. If the phone rings,this may cause a spark that could ignite gaso-line fumes, resulting in fire and injury.
WARNING
Carbon monoxide is a poisonous, colorless,and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumes insidethe vehicle, make sure the passenger com-partment is ventilated, and immediately returnthe vehicle to a trained and qualified Volvoservice technician for correction.
Demanding driving
In demanding driving conditions, such as whentowing a trailer or driving in hot weather or forprolonged periods at high altitudes, it may be agood idea to switch to a higher-octane fuel
(AKI10 91 or higher) or to switch to another
brand of gasoline in order to fully utilize the vehi-cle's engine capacity and optimize traction.

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certainengine 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

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.
NOTE
The vehicle cannot be started if the hybridbattery is discharged.
NOTE
If the starter battery has been discharged tothe extent that the vehicle does not have nor-mal electrical functions and the engine mustthen be jump-started with an external batteryor a battery charger, the Start/Stop functionmay remain activated. If the Start/Stop func-tion shortly thereafter auto-stops the engine,there is a huge risk that auto-start of theengine will fail due to insufficient batterycapacity since the battery had not had time torecharge.
If the vehicle has been jump-started or ifthere has not been enough time for the bat-tery to be charged with a battery charger, theStart/Stop function should be temporarilydeactivated until the battery has beenrecharged by the vehicle. At an ambient tem-perature of about +15°C (about 60°F), thebattery must be charged by the vehicle for atleast one hour. At lower ambient tempera-tures, the charging time can increase to3-4 hours. It is advisable to charge the batterywith an external battery charger.

Driving with a trailer
There are a number of things to consider whentowing a trailer, such as the towbar, the trailerand how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehi-cle's curb weight. The total weight of all passen-gers and any installed accessories, e.g. towbar,reduces the vehicle's load-carrying capacity bythe corresponding amount.
Towbars used on the vehicle must beapproved for the applicable use.
Distribute the load on the trailer so that theweight on the towbar complies with thespecified maximum towball weight. Thetongue weight is calculated as part of thevehicle's payload.
Increase the tire pressure to the recom-mended pressure for a full load.
The engine is subjected to more load thanusual when towing a trailer.
Towing a trailer affects the vehicle's han-dling, durability and driving economy.
Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
On long and steep downgrades, the vehicle'sbrakes are subjected to much more loadthan usual. When manually shifting, down-shift and adapt speed accordingly.
STARTING AND DRIVING
}}
* Option/accessory.435
Follow applicable regulations regarding per-mitted speed and weight.
Drive slowly when towing a trailer up a longand steep incline.
The maximum trailer weights given only applyto altitudes up to 1000 meters (3280 feet)above sea level. At higher altitudes, enginepower (and thus the vehicle's climbing ability)is decreased due to the reduced air density,and the maximum trailer weight must there-fore be reduced. The weight of the vehicleand trailer must be decreased by 10% foreach additional 1000 m (3280 feet) or partthereof.
Avoid driving with a trailer on inclines of morethan 12%.
Avoid overloading and other incorrect use.
The trailer's brakes must be balanced withthe vehicle's brakes to help ensure safestops (follow applicable local regulations).
CAUTION
Bumper-attached trailer hitches must notbe used on Volvos, nor should safetychains be attached to the bumper.
Trailer hitches attaching to the vehiclerear axle must not be used.
Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
NOTE
The optional detachable trailer hitch may notbe available in all markets or on all models.Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer,high altitude and lower fuel grade than rec-ommended are factors that can significantlyincrease the vehicle's fuel consumption.
Trailer weights
WARNING
Please adhere to the recommendations provi-ded for trailer weight. If the recommendationsare not followed, the vehicle and trailer maybe difficult to control during evasive maneu-vers and braking.
NOTE
The specified maximum trailer weights arethose permitted by Volvo. National vehicleregulations may set additional restrictions ontrailer weight and speed. The trailer hitchesmay be certified for higher towing weightsthan the vehicle is permitted to tow.
Self-leveling suspension *
The vehicle's self-leveling system attempts tokeep the vehicle at a constant level, regardless ofload (up to the maximum permitted weight).When the vehicle is stationary, the rear end of thevehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weather
In certain conditions, there is a risk of overheat-ing when driving with a trailer. If overheating ofthe engine and drive system is detected, a warn-ing symbol will illuminate in the instrument paneland a message will appear.

Trailer Stability Assist*
Trailer Stability Assist (TSA12) is a functiondesigned to help stabilize a vehicle that is tow-ing a trailer when the vehicle and trailer havebegun to sway. The function is part of the Elec-
tronic Stability Control system ESC13.
Reasons for swaying
A vehicle towing a trailer may begin to sway forvarious reasons. Normally this only occurs at highspeeds. However, if the trailer is overloaded orunevenly distributed, e.g. too far back, there is arisk of swaying even at low speeds.
Swaying may be caused by factors such as:
The vehicle and trailer are hit by a sudden,strong crosswind.
The vehicle and trailer are traveling on anuneven road or over a bump.
Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult orimpossible to stop it. This makes the vehicle andtrailer difficult to control and there is a risk ofswerving into oncoming traffic or driving off theroad.
Trailer Stability Assist function
Trailer Stability Assist continuously monitors thevehicle's movements, particularly lateral move-
ments. If swaying is detected, the brakes areapplied individually on the front wheels, which hasa stabilizing effect on the vehicle and trailer. Thisis often enough to enable the driver to regaincontrol of the vehicle.
If the Trailer Stability Assist function's firstattempt is not adequate to stop the swayingmotion, the brakes are applied on all wheels andengine power is temporarily reduced. As theswaying motion begins to decrease and the vehi-cle and trailer have once again become stable,TSA stops regulating the brakes/engine powerand the driver regains control of the vehicle.
NOTE
Trailer Stability Assist is deactivated if thedriver selects the sport mode by deactivatingESC in the center display's menu system.
Trailer Stability Assist may not intervene if thedriver tries to compensate for the swaying motionby moving the steering wheel rapidly, becausethe system will then not be able to determine if itis the trailer or the driver causing the swaying.
