Towing recommendations
Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to regula-tions regarding maximum towing speed, lengthand type of towing device, lighting, etc.
Towing your vehicle behind another
vehicle
1. After securely attaching the towing line to both vehicles, put the gear selector in posi- tion N and release the parking brake.
2. Put the ignition in mode II by turning the
start knob to START (without depressing
the brake pedal) and hold it in this position
for approx. 4 seconds. Release the knob.
3. Put the gear selector in position N and
release the parking brake.
4. The towing vehicle can now begin driving.
5. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This will help prevent jar-ring movements of the vehicle being towed.
6. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• If the vehicle's battery is dead, an auxiliary battery will be necessary to provide cur-rent for releasing the electric parkingbrake and to move the gear selector from the
P position to N. If this is not possible,
use the shiftlock override procedure tomanually release the gear selector from P
and move it to N.
• Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable tow-ing speed.
• Maximum distance with front wheels onground: 50 miles (80 km).
• The vehicle should only be towed in theforward direction.
WARNING
• When the vehicle is being towed, the igni- tion should be in mode
II (in mode I, all of
the vehicle's airbags are deactivated).
• The remote key must remain inside the vehicle.
• The power brakes and power steering willnot function when the engine is not run-ning. Approximately 5 times more pres-sure will be required on the brake pedaland the steering wheel will be considera-bly harder to turn.
• The towing eyelets must not be used forpulling the vehicle out of a ditch or forany similar purpose involving severestrain.

Fuel Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (detergent
additives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddrivability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo does not recommend the use of exter- nal fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. andCanadian regulations require that pumps deliver-ing unleaded gasoline be labeled "UNLEADED".Only these pumps have nozzles which fit yourvehicle's filler inlet. It is unlawful to dispense lea-ded fuel into a vehicle labeled "unleaded gaso-line only". Leaded gasoline damages the three-way catalytic converter and the heated oxygensensor system. Repeated use of leaded gasolinewill lessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicle inspection programs will make detection of mis-fueling easier, possibly resulting in emission testfailure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane 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 allows the use of the following "oxygen- ated" fuels; however, the octane ratings listedmust still be met.

To refuel:
1. Open the fuel filler door. Do not refuel with
the engine running 3
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 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.

Driving with a trailer
When towing a trailer, always observe the legal requirements of the state/province.
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par- ticular problems, but take into consideration:
• Increase tire pressure to recommended full pressure.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
• If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy.
• It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safe stop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
• When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.

Battery drain Your vehicle's electrical functions drain the bat- tery to varying extents.
Avoid using ignition mode
II as much as posssi-
ble, or electrical functions that require a great deal of electrical current when the engine is notrunning. Using ignition mode I whenever possible con-
sumes less electrical current. Functions that require a great deal of electrical current include:
• the climate system blower
• headlights
• wipers
• infotainment system (especially at high vol- ume).
If the battery's charge level is low, a text message will appear in the instrument panel. The vehicle'senergy-saving function will then turn off orreduce certain functions that are currently con-suming electrical current. If the battery needs to be recharged, start the engine and let it idle for at least 15 minutes ordrive the vehicle (driving charges the batteryfaster than letting the engine idle).

Starting the engine
The engine can be started using the start knob on the tunnel console if there is a remote key inthe passenger compartment.

STARTING AND DRIVING
358If
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.
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.
