Auto-stopping the engineNormally, when Start/Stop is activated and the brakes are applied until the vehicle comesto a standstill, the engine will auto-stop auto-matically if the driver keeps the brake pedal
depressed .
To remind the driver that the enginehas been auto-stopped, theStart/Stop symbol will illuminate inthe instrument panel and remain on
until the engine restarts.
If the ECO function* (ECO* (p. 261)) is activated, theengine may auto-stop beforethe vehicle comes to a com-plete standstill.
Auto-starting the engineThe engine restarts as soon as the driver releases the brake pedal.
Deactivating Start/StopIn certain situations (e.g., driving in heavy, stop-and-gotraffic), it may be preferableto deactivate Start/Stop. This is done by pressing the button in the center console.
The indicator light in the button will go out. Start/Stop will remain deactivated until the button is pressed again or until the engine isswitched off and restarted by the driver.

Engine and cooling system
Under special conditions, for example when driving in hilly terrain, extreme heat or withheavy loads, there is a risk that the engine andcooling system will overheat. Proceed as follows to avoid overheating the engine. •Maintain a low speed when driving with a trailer up long, steep hills. For informa-tion, see Towing a trailer (p. 281)
• Do not turn the engine off immediatelywhen stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after theengine has been switched off.
•
Remove any auxiliary lights from in front of the grille when driving in hot weatherconditions.
• Do not exceed engine speeds of4500 rpm if driving with a trailer in hillyterrain. The oil temperature could becometoo high.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
• When the engine is not running, avoid using ignition mode
II. Many electrical
systems (the audio system, the optionalnavigation system, power windows, etc)will function in ignition modes 0 and I.
These modes reduce drain on the battery.
• Please keep in mind that using systems,accessories, etc., that consume a greatdeal of current when the engine is notrunning could result in the battery beingcompletely drained. Driving or having theengine running for approximately15 minutes will help keep the batterycharged.
• The optional 12-volt socket in the cargoarea (p. 141) area provides electrical cur-rent even with the ignition switched off,which drains the battery.
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo serv-ice technician before driving long distances.Your retailer will also be able to supply youwith bulbs, fuses, spark plugs and wiperblades for your use in the event that problemsoccur. As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and that fuel consumption is normal.
• Check for fuel, oil, and fluid leakage.
• Have the transmission oil level (p. 377)checked.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that areworn (p. 290). Check tire pres-sure (p. 297).
• The brakes, front wheel alignment, andsteering gear should be checked by atrained and qualified Volvo service techni-cian only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle ifyou detect engine misfire, noticeable lossof power or other unusual operating con-ditions, such as engine overheating orbackfiring. A properly tuned engine willhelp avoid malfunctions that could dam-age the three-way catalytic converter.
• Do not park your vehicle over combusti-ble materials, such as grass or leaves,which can come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
• Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cat-alytic converter or exhaust system over-heating.
• Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehiclemay be illegal and can cause three-waycatalytic converter or exhaust systemoverheating. This includes: altering fuelinjection settings or components, alteringemission system components or location or removing components, and/or repea-ted use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readingsare fed into a control module that continu-ously monitors engine functions and controlsfuel injection. The ratio of fuel to air into theengine is continuously adjusted for efficientcombustion to help reduce harmful emis-sions.

Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions.
Economical driving conserves natural resources
Observe the following rules:
• Bring the engine to normal operating tem- perature as soon as possible by drivingwith a light foot on the accelerator pedalfor the first few minutes of operation. Acold engine uses more fuel and is subjectto increased wear.
• Whenever possible, avoid using the vehi-cle for driving short distances. This doesnot allow the engine to reach normaloperating temperature.
• Drive carefully and avoid rapid accelera-tion and hard braking.
• Use the transmission's Drive (
D) position
as often as possible and avoid using kick-down.

6. If your vehicle will be towing a trailer, loadfrom your trailer will be transferred to your vehicle.
WARNING
•Exceeding the permissible axle weight, gross vehicle weight, or any otherweight rating limits can cause tireoverheating resulting in permanentdeformation or catastrophic failure.
• Do not use replacement tires withlower load carrying capacities than thetires that were original equipment onthe vehicle because this will lower thevehicle's GVW rating. Use only tireswith the correct load carrying capacity.Consult your Volvo retailer for informa-tion.
Tire specifications – terminology
The following is a glossary of tire-related terms. The tire suppliers may have additional mark- ings, notes or warnings such as standardload, radial tubeless, etc.
• Tire information placard
: A placard
showing the OE (Original Equipment) tire sizes, recommended inflation pressure,and the maximum weight the vehicle cancarry.
• Tire Identification Number (TIN)
: A
number on the sidewall of each tire pro-viding information about the tire brandand manufacturing plant, tire size anddate of manufacturer.
• Inflation pressure
: A measure of the
amount of air in a tire.
• Standard load
: A class of P-metric or
Metric tires designed to carry a maximumload at 35 psi [37 psi (2.5 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetires load carrying capability.
• Extra load
: A class of P-metric or Metric
tires designed to carry a heavier maxi-mum load at 41 psi [43 psi (2.9 bar) forMetric tires]. Increasing the inflation pres-sure beyond this pressure will notincrease the tire's load carrying capabil-ity. •
kPa
: Kilopascal, a metric unit of air pres-
sure.
• PSI
: Pounds per square inch, a standard
unit of air pressure.
• B-pillar
: The structural member at the
side of the vehicle behind the front door.
• Bead area of the tire
: Area of the tire
next to the rim.
• Sidewall of the tire
: Area between the
bead area and the tread.
• Tread area of the tire
: Area of the perim-
eter of the tire that contacts the roadwhen mounted on the vehicle.
• Rim
: The metal support (wheel) for a tire
or a tire and tube assembly upon whichthe tire beads are seated.
• Maximum load rating
: a figure indicating
the maximum load in pounds and kilo-grams that can be carried by the tire. Thisrating is established by the tire manufac-turer.
• Maximum permissible inflation pressure
: the greatest amount of air
pressure that should ever be put in the tire. This limit is set by the tire manufac-turer.
• Recommended tire inflation pressure
:
inflation pressure, established by Volvo,which is based on the type of tires thatare mounted on a vehicle at the factory.This information can be found on the tireinflation placard(s) located on the driver's

CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If the pressure remains below 22 psi (1.8 bar) after approximately sevenminutes, turn off the compressor. In thiscase, the hole is too large to be sealed andthe vehicle should not be driven.
10. Switch off the compressor and discon-
nect the electrical wire from the 12-volt socket.
11. Unscrew the hose from the tire’s inflation valve and reinstall the valve cap.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
12. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to distributethe sealing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire Pressure Monitoring System (TPMS), theuse of the sealing compound may lead toincorrect tire pressure readings or in rarecases, damage to the tire pressure sensor.Use the tire sealing system to check andadjust the damaged tire's inflation pres-sure.
NOTE
•Safely stow the tire sealing system in a convenient place as it will soon beused again to check the tire’s inflationpressure.
• The empty bottle of sealing compoundcannot be removed from the bottleholder. Consult a trained and qualifiedVolvo service technician to have thebottle removed and properly disposedof.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur whiledriving, reduce speed and park the vehiclein a safe place. Recheck the tire forbumps, cracks, or other visible damage,and recheck its inflation pressure. If thepressure is below 19 psi (1.3 bar), do notcontinue driving. Have the vehicle towedto a trained and qualified Volvo servicetechnician.
Tire sealing system – checking inflation pressure
The tire sealing system can also be used to check the tires' inflation pressure.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as
described in stage 1, see Tire sealing
system* – sealing hole (p. 316).
2. Refer to the inflation pressure table in this chapter for the correct inflation pressure.If the tire needs to be inflated, start thetire sealing system’s compressor. If nec-essary, release air from the tire by turningthe air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
WARNING
If you interrupt your trip for more than 1 hour, check the inflation pressure in thedamaged tire again before continuing.

Tire sealing system* – inflating tires
The tire sealing system can be used to inflate the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s inflation valve and screw the hose con- nector onto the valve as tightly as possi-ble by hand.
5. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
6. Start the vehicle’s engine.WARNING
• The vehicle’s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be surethe vehicle is parked in a well ventilatedplace, or outdoors, before using thesystem. The parking brake should besecurely applied and the gear selectorshould be in the
P (park) position.
• Children should never be left unatten-ded in the vehicle when the engine isrunning.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to get a clear reading from the pressuregauge.
8. Refer to the tire inflation table in this chapter for the correct inflation pressure.If the tire needs to be inflated, start thetire sealing system’s compressor (pressthe on/off switch to position I). If neces-sary, release air from the tire by turningthe air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
9. Turn off the compressor (press the on/off switch to position 0) when the correct
inflation pressure has been reached.
10. Unscrew the hose from the tire’s inflation valve and reinstall the valve cap.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
11. Disconnect the electrical wire from the
12-volt socket.
