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 if youdetect engine misfire, noticeable loss ofpower or other unusual operating condi-tions, such as engine overheating or back-firing. A properly tuned engine will helpavoid malfunctions that could damage thethree-way catalytic converter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, whichcan 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 cata-lytic converter or exhaust system over-heating.
Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse 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. Readings are fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.

Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (driv-ing charges the battery faster than lettingthe engine idle).

Jump starting using another battery If the start battery is discharged, current from another battery can be used to start the vehi-cle.
Jumper cable connecting points.
CAUTION
The charging point of the vehicle is only intended for jump starting the vehicle inquestion. The charging point is notintended for jump-starting another vehicle.Using the charging point to start anothervehicle could cause a fuse to blow, whichwould cause the charging point to stopworking.
If a fuse has blown, 12 V Battery Fuse failure
Service required will be displayed in the instrument panel. Volvo recommends contact- ing an authorized Volvo workshop. To avoid short circuits or other damage, the following steps are recommended when jumpstarting the battery:
1. Put the ignition in mode
0.
2. Make sure the auxiliary battery (the bat- tery used to jump start the discharged battery) has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and makesure that the vehicles are not touchingeach other.
4. Clamp the red jumper cable onto the auxil- iary battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to pre- vent short circuits with other componentsin the engine compartment.
5. Fold back the cover over your vehicle'spositive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start terminal (2).
7. Clamp the black jumper cable onto the auxiliary battery's negative (-) terminal (3). 8. Clamp the other end of the black jumper
cable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securely attached to help prevent sparks whilejump starting.
10. Start the engine of the assisting vehicle and let it run for a few minutes at a higheridling speed than normal, about1500 rpm.

STARTING AND DRIVING
44211. Start your vehicle's engine. If the engine
does not start, allow an additional 10 minutes of charging time and then try tostart the engine again.
NOTE
When the engine is started under normal conditions, the vehicle's electrical drivemotor is prioritized – the gasoline engineremains off. This means that after the startknob has been turned clockwise, the elec-tric motor has "started" and the vehicle isready to be driven. Start of the electricmotor is indicated by the indicator lights onthe instrument panel going out and its pre-selected theme illuminating.
CAUTION
Do not touch the connections between the cable and the vehicle during the startattempt. Risk of sparking.
12. Remove the jumper cables in the reverseorder ‒ first the black cables and then the
red cables. Make sure that none of the clamps of the black jumper cables come into contactwith either vehicle's positive (+) jump startterminals or either of the red jumpercable's connected clamps.
