Fuel
Volvo recommends the use of detergent gaso-line to control engine deposits.

Deposit control gasoline (gasoline with
detergent additives)
Detergent gasoline is effective in keeping injec-tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddriveability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.

NOTE
Volvo recommends not using external fuelinjector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.

Unleaded fuel
All Volvo vehicles have a three-way catalytic con-verter and must only use unleaded gasoline. USand Canadian regulations require that pumpsdelivering unleaded gasoline are labeled"UNLEADED". Only the nozzles of these pumpswill fit in your vehicle's fuel filler inlet. It is unlaw-ful to dispense leaded fuel into a vehicle labeled"unleaded gasoline only". Leaded gasoline dam-ages the three-way catalytic converter and theheated oxygen sensor system. Repeated use ofleaded gasoline will lessen the effectiveness of
the emission control system and could result inloss of emission warranty coverage. State andlocal vehicle inspection programs will makedetection of misfueling easier, possibly resultingin emission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain anoctane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl(MMT). If such fuels are used, your EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle to a trained and qualified Volvoservice technician for service.

Gasoline containing alcohol and ethers,
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing"oxygenates" which are usually alcohols orethers. In some areas, state or local laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. To meet seasonal air quality standards,some areas require the use of "oxygenated" fuel.
Volvo permits the use of the following "oxygen-ated" fuels. However, the specified octane ratingsmust still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volumemay be used. Ethanol may also be referred to asEthyl alcohol, or "Gasohol".
Ethers - MTBE/ETBE: Fuels containing up to22% MTBE/ETBE by volume may be used.

Methanol
Do not use gasolines containing methanol(methyl alcohol, wood alcohol). This practice canresult in vehicle performance deterioration andcan damage critical parts in the fuel system. Suchdamage may not be covered under the NewVehicle Limited Warranty.

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.
–Charge the battery by starting the engineand let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

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.

Trailer rear fog light
When a trailer is connected, the vehicle's rear foglight may not illuminate and rear fog light func-tionality is instead transferred to the trailer. If thisis the case, check to see if the trailer is equippedwith a rear fog light before activating the vehicle's
fog lights when driving with a trailer to helpensure safe operation.
Checking trailer lights *
Automatic check
When the trailer has been connected to the vehi-cle's electrical system, its lights can be checkedby automatically activating them. This functionhelps the driver check that the trailer's lights arefunctioning correctly before starting to drive.
In order to perform this check, the vehicle mustbe switched off.
