Starting the vehicle
The vehicle can be started using the start knob in the tunnel console when the remote key is inthe passenger compartment.
Start knob in the tunnel console.
WARNING
Before starting:
• Buckle your seat belt.
• Adjust the seat, steering wheel and mir- rors.
• Make sure you can fully depress thebrake pedal. The remote key is not physically used to start theignition because the vehicle is equipped with thekeyless Passive Start system. To start the vehicle:
1. The remote key must be inside the vehicle.
For vehicles with Passive Start, the key must be in the front section of the passengercompartment. With the optional keyless lock- ing/unlocking function *, the key can be any-
where in the vehicle.
2. Press and hold down the brake pedal 1
as far
as possible.
3. Turn the start knob clockwise and release. The control will automatically return to the original position.
WARNING
• Never use more than one inlay mat at a time on the driver's floor. If any other typeof floor mat is used, remove the originalmat from the driver's seat floor beforedriving. All types of mats must be securelyanchored in the attachment points in thefloor. Make sure the floor mat does notimpede the movement of the brake pedalor accelerator pedal in any way, as thiscould be a serious safety hazard.
• Volvo's floor mats are specially manufac-tured for your vehicle. They must be prop-erly secured in the attachment points inthe floor to help ensure they cannot slideand become trapped under the pedals.
The starter motor will crank until the enginestarts or until its overheating protection is trig-gered.
1 If the vehicle is moving, it is only necessary to turn the start knob clockwise to start the engine.

Location of the backup reader in the tunnel console.
If the Vehicle key not found message is shown
in the instrument panel at start, place the remote key at the backup reader and then make a newstart attempt.
NOTE
When the remote key is placed in the backup reader, make sure that no other vehicle keys,metal objects or electronic devices (e.g. cellu-lar phones, tablets, laptops or chargers) are inthe backup reader. Multiple vehicle keys closeto each other in the backup reader can dis-rupt their functionality.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before startinga new attempt. Starting capability increases ifthe starter battery is given time to recover.
WARNING
Never remove the remote control key from
the vehicle while driving or the vehicle is being towed.
WARNING
• Always remove the remote key from the passenger compartment when you leavethe vehicle and make sure the ignition is in mode
0.
• Always put the gear selector in
P and
apply the parking brake before leaving the vehicle. Never leave the vehicle unsu-pervised while the engine is running.
• Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by the vehi-cle contain carbon monoxide, which isinvisible and odorless but very toxic.
WARNING
Always take along the remote control key when leaving the vehicle and make sure thatthe vehicle electrical system is in ignition mode
0 – especially if there are children in
the vehicle.
NOTE
With a cold start, idling speed may be consid- erably higher than normal for certain enginetypes. This is done to get the emissions sys-tem up to normal operating temperature asquickly as possible, which minimizes exhaustemissions and protects the environment.
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. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it has reachedthe proper operating temperature.
• The engine should be idling when thegear selector is moved. Never accelerateuntil the gear is fully engaged. Accelerat-ing rapidly before a gear is properlyengaged could lead to harder wear ofcomponents.
• To help prevent the transmission oil from overheating, select
P or N when idling at
a standstill for prolonged periods of time.

Ignition modes
The vehicle's ignition can be put in various modes (levels) to make different functions availa-ble.
To enable the use of a limited number of func- tions when the engine is not running, the ignition can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual. The following table shows which functions are available in each ignition mode:
ModeFunctions
0 •The odometer, clock and tem- perature gauge are illuminated A

Braking assist after a collision In a collision in which the activation level is reached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos- sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely. The brake lights and hazard warning flashers are activated during braking. When the vehicle has stopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal. This function assumes that the brake system is intact after a collision. Brake assist is part of the Rear Collision Warning and Blind Spot Information safety systems.

Transmission The transmission is part of the vehicle's driveline (power transmission) between the engine andthe drive wheels. The function of the transmis-sion is to change gears depending on speedand power needs.
The vehicle has an 8-speed automatic transmis- sion. The number of gears allows the engine'storque and power band to be effectively utilized.Two of the gears are overdrive gears that savefuel when driving at a constant engine speed.Manual shifting is also possible. The instrumentpanel shows the gear currently in use.
CAUTION
Check the operating temperature of the transmission to help avoid damage to any ofthe drive system components. If there is a riskof overheating, a warning symbol will appearin the instrument panel and a text messagewill be displayed. Follow the recommenda-tions given.
Symbols in the instrument panelIf a problem should occur with the transmission, a symbol and a message will appear in the instru-ment panel.

The kickdown function
Kickdown is used when maximum acceleration is needed, e.g. when passing.
When the accelerator pedal is depressed all the way to the floor (past the normal full acceleratorposition), the transmission will automaticallyengage kickdown, i.e. immediately shift down to alower gear. If the accelerator pedal is released from the kick- down position, the transmission will automaticallyshift up again.
Safety function
The transmission control module is equipped with a downshift protection feature to help prevent theengine from overheating. In some conditions, the transmission will prevent downshifting/kickdown if this would lead to suchhigh engine speed (rpm) that the engine couldbe damaged. If the driver still attempts downshift-ing or kickdown at a high rpm, nothing will hap-pen and the original gear will remain selected. With kickdown, the vehicle can downshift one or more steps at a time depending on the enginespeed. The vehicle upshifts when the engine rea-ches its maximum rpm to prevent engine dam-age.

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 or location or removing components, and/orrepeated use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content 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.

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 not be 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 not be 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 are those 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 to keep 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 weatherIn 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 panelalong with a message.

Trailer Stability Assist
*
Trailer Stability Assist (TSA 8
) is a function
designed 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 ESC 9
.
Reasons for swayingA vehicle towing a trailer may begin to sway for various 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 functionTrailer 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 first attempt 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 the driver selects the sport mode by deactivating
ESC in the center display's menu system.
Trailer Stability Assist may not intervene if the driver 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.
