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.

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power 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 audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

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. The automatic transmission selects the optimalgear for the current load and engine speed.
Steep inclines
Do not lock the automatic transmission into a higher gear than what the engine can handle
‒ it
is not always preferable to drive in high gears at low rpm.
Parking on a hill
1. Depress the brake pedal.
2. Apply the parking brake.3. Put the gear selector in P.
4. Release the brake pedal.Put chocks behind the wheels when the vehicle is parked on a hill with a trailer attached.

Towing using a towlineThis section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applicable speed limit regulations.
Preparations and towing
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
• Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
WARNING
•
Ignition mode
II must be active – all air-
bags are deactivated in ignition mode I.
• Always have the remote key in the vehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much more effortthan normal. 1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.3.
Put the vehicle in ignition mode II – without
pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral ( N) and
release the parking brake. If the battery charge level is too low, it may not be possible to release the parking brake.Connect an auxiliary battery to the vehicle ifthe battery is discharged.
> The towing vehicle can now start driving.
5. Keep the towline taut when the towing vehi- cle slows down by applying light pressure to the brake pedal. This will help avoid jarringmovements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.
CAUTION
Attempting to tow with the engine running could result in damage to the three-way cata-lytic converter.

Limitations
• Main channel vs. sub-channels (FM only)
:
The main channel is the only channel that can receive in hybrid mode (both digital andanalog). If a frequency has sub-channels,they are broadcast in digital mode only. Themain FM channel will be displayed as, forexample, "WRIF-FM HD1". The sub-FMchannels will be displayed as"WRIF-FMHD2", "WRIF-FM HD3", etc.
• Reception coverage area
: Due to current
IBOC transmitter power limitations, thereception coverage area in digital mode issomewhat more limited than the station'sanalog coverage area. Be aware that, like allradio transmission technology, terrain, time ofday, vegetation and buildings can have apositive or negative effect on radio reception.
• Analog to digital/digital to analog blend-ing
: Analog to digital blending will occur as
the signal strength reaches a preset thresh-old in the receiver. This will be noticeable infringe areas (areas with weak reception) andis normal.
NOTE
There may be a noticeable difference in sound quality when a change from analogueto digital or digital to analogue occurs, suchas:
• Volume increase or decrease
• Equalizer settings, i.e., Bass/ Midrange/Treble cut or boost
• Time alignment (Digital program materialin extreme cases can be as much as 8seconds behind the analogue). This willnoticeable as a "stuttering" effect.
The above items are dependant on thebroadcaster's equipment settings and donot indicate a fault in the vehicle's radioreceiver or antenna systems .
