How to Jump Start a Volvo XC90

1. Clamp the red jumper cable onto the auxiliary battery's positive (+) terminal (1), taking care to avoid short circuits with other engine compartment parts.
2. Fold back the cover over your vehicle's positive (+) jump start terminal (2).
3. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start terminal (2).
4. Clamp the black jumper cable onto the auxiliary battery's negative (-) terminal (3).
5. Clamp the other end of the black cable to your vehicle's negative (-) ground point (4) and check all clamps are secure.
6. Start the assisting vehicle's engine and let it run a few minutes at about 1500 rpm, then start the vehicle with the dead battery.
7. Remove the jumper cables in reverse order, black cables first and then red cables.

• Do not touch the connections between the cable and the vehicle during the start attempt, because of sparking risk.
• Black clamps must not touch either vehicle's positive (+) jump start terminals or the red cable clamps.
• Use the connection points in the engine compartment, not the battery terminals in the luggage/cargo area.
