Hill Descent Control
The function for assisting when driving downhill,Hill Descent Control (HDC), is a low-speedfunction with increased engine braking. Thefunction makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients by only using the accelerator pedal,without applying the brakes.
The function is included in the Off Road drivemode.
HDC is designed for driving on rough roads atlow speeds and downhill gradients with slipperyor otherwise difficult road surfaces. The driverdoes not need to use the brake pedal but caninstead focus on steering.

WARNING
HDC is only intended to be a supplementarybraking aid and it does not function in all sit-uations.
The driver is always ultimately responsible foroperating the vehicle in a safe manner.

Function
Hill Descent Control allows the vehicle to moveforward or backward at very low speeds assistedby the brake system. The driver can increase thespeed by pressing the accelerator pedal. Whenthe accelerator pedal is released, the vehicle willreturn to very low speed regardless of how steep
the hill is and without the brakes needing to beapplied. The brake lights will illuminate when thefunction is activated.
The driver can brake to stop or slow the vehicleat any time by depressing the brake pedal.
HDC is activated along with Low Speed Control(LSC), which facilitates and improves traction andcontrol on rough and slippery surfaces. The sys-tem is intended to be used at low speeds, up toapproximately 40 km/h (25 mph).
To keep in mind when using HDC
If the function is switched off while driving ona steep downhill gradient, braking effect willbe gradually reduced.
HDC can be used in gear positions D and R,and in manual gears 1 or 2.
It is not possible to manually shift to thirdgear or higher when HDC is active.

NOTE
When LSC with HDC is activated in the OFFROAD drive mode, the feel of the acceleratorpedal and engine response will change.

NOTE
This drive mode is not designed to be usedfor normal street driving.
NOTE
The function is deactivated when driving athigh speeds and must be reactivated at lowerspeeds if so desired.

Using the electric motor only
When using the electric motor, Volvo TwinEngine provides a combination of good fueleconomy, low emissions and high performance.
For energy-efficient driving:
Select the Pure drive mode to help maximizedriving range using only the electric motor.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel's hybrid gauge to see avail-able electric power and avoid starting thecombustion engine unnecessarily.
When braking is necessary, brake gentlyusing the brake pedal. This will recharge thehybrid battery.
Activate the Hold function in the Functionview at high speeds when traveling fartherthan is possible using the hybrid battery'scapacity.
Reduce current consumption in the passen-ger compartment by reducing e.g. fan speed,electric heating, or air conditioning use.
Also follow the general economical driving adviceregarding speed, tires and load to maximizerange.

Factors affecting electric motorrange
A number of factors affect the electric motor'sdriving range. The ability to achieve a long driv-ing range varies according to the outside condi-tions and to how the vehicle is driven.
The certified value for the distance that can bedriven using the electric motor should not beconsidered an expected driving range. The actualrange is dependent on a number of factors.
Factors affecting driving range
The driver can influence some factors affectingdriving range, but not all.
The longest range is achieved under very favora-ble conditions when all factors positively influ-ence range.

Slippery driving conditions
For 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 tiresby law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under con-trolled conditions to learn how the vehicle reacts.

Driving through standing water
Driving the vehicle through a deep pool of stand-ing water on a water-covered roadway is calledfording. This must be done with great caution.
To prevent damage to the vehicle when drivingthrough water (e.g. on flooded roads):
Do not drive in water higher than the floor ofthe vehicle. If possible, check the depth ofthe water at its deepest point before drivingthrough it. Be particularly careful when driv-ing through flowing water.
Always select the Off Road drive modebefore driving in water to ensure the gasolineengine is running.
Do not drive faster than walking speed.
Do not stop the vehicle in the water. Drivecarefully forward or back the vehicle out ofthe water.
Remember that waves created by passingvehicles could cause the water level to riseabove the vehicle's floor level.
Avoid driving through salt water to help avoidthe risk of corrosion.
CAUTION
Parts of the vehicle (e.g. engine, transmission,driveline, electrical components, etc.) can bedamaged if the vehicle is driven through waterhigher than its floor level. Damage to anycomponents caused by flooding, vapor lock orinsufficient oil is not covered under warranty.
If the engine stalls while the vehicle is inwater, do not attempt to restart it. Have thevehicle towed on the bed of a tow truck to aworkshop - an authorized Volvo workshop isrecommended.

CAUTION
Because it can be difficult to determine thewater depth, avoid driving through standing orrunning water.
When you have passed the water, press lightly onthe brake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc. canmake the brake linings slippery, resulting indelayed braking effect.
If the vehicle is equipped with a trailer couplingcontact, clean the contact after driving in water ormud.

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
or location or removing components, and/orrepeated use of leaded fuel.

NOTE
Unleaded fuel is required for vehicles withthree-way catalytic converters.

Heated oxygen sensors
The heated oxygen sensors monitor the oxygencontent of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Battery drain
The electrical functions in the vehicle drain thebattery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Useignition mode I instead, as this uses less electri-cal current.
Note that certain accessories may also drainpower 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 audiosystem.

Jump starting using another battery
If the start battery is discharged, current fromanother battery can be used to start the vehicle.
Jumper cable connecting points.

CAUTION
The charging point of the vehicle is onlyintended for jump starting the vehicle in ques-tion. The charging point is not intended forjump-starting another vehicle. Using thecharging point to start another vehicle couldcause a fuse to blow, which would cause thecharging point to stop working.
If a fuse has blown, 12 V Battery Fuse failureService required will be displayed in the instru-ment panel. Volvo recommends contacting anauthorized Volvo workshop.
To avoid short circuits or other damage, the fol-lowing steps are recommended when jump star-ting the battery:
1.Put the ignition in mode 0.
2.Make sure the auxiliary battery (the batteryused 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 auxiliarybattery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to preventshort 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 cableto 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 jumpercable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securelyattached to help prevent sparks while jumpstarting.
10. Start the engine of the assisting vehicle andlet it run for a few minutes at a higher idlingspeed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the enginedoes not start, allow an additional 10minutes of charging time and then try to startthe engine again.
NOTE
When the engine is started under normalconditions, 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 thecable and the vehicle during the start attempt.Risk of sparking.

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).

NOTE
To facilitate towing a trailer in a vehicle equip-ped with pneumatic suspension*, select: the
Suspension ControlDynamic setting inIndividual drive mode.
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,driving at high altitudes and fuel quality arefactors that significantly increase a vehicle'sfuel 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.

Trailer Stability Assist*
Trailer Stability Assist (TSA8) 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 ESC9.
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.
