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's positive (+) 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.
11. Start your vehicle's engine. If the engine does not start, allow an additional 10minutes 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.

Spare wheel 13
The spare wheel is a Temporary Spare and can be used to temporarily replace a punc- tured tire on one of the vehicle's regularwheels.
The spare tire is only intended for temporary use. Replace it with a normal wheel as soon aspossible. The driving characteristics of the vehicle change and ground clearance reduces whenthe spare wheel is used. Do not wash the vehi-cle in an automatic car wash while using theTemporary Spare. The recommended tire pressure must be maintained regardless of at which position thetemporary spare wheel is used on the vehicle. If the spare wheel is damaged, a new one can be purchased from a Volvo retailer.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as atemporary replacement for a puncturedtire. It must be replaced as soon as possi-ble by a standard tire. Road holding andhandling may be affected with the "Tempo-rary Spare" in use. Do not drive faster than80 km/h (50 mph).
