Jump Starting - Volvo XC90 Owner's Manual

Starting with a donor battery
The battery is fitted in the rear of the car (see
page 222) but there are also connection points
under the bonnet.
If the battery is flat then the car can be
started with current from another battery.
When jump starting the car, the following
steps are recommended to avoid short cir-
cuits or other damage:
1. Turn the remote control key to key posi-
tion 0.
2. Check that the donor battery has a volt-
age of 12 V.
3. If the donor battery is installed in another
car - switch off the donor car's engine
and make sure that the two cars do not
touch each other.
4. Connect one of the red jump lead's
clamps to the donor battery's positive
terminal (1).
IMPORTANT
Connect the start cable carefully to avoid
short circuits with other components in the
engine compartment.
5. Connect the red jump lead's other clamp
onto the car's positive terminal (2).
> A spring-loaded cover over the car's
extra positive terminal must first be
folded up!
6. Connect one of the black jump lead's
clamps to the donor battery's negative
terminal (3).
7. Fit the second clamp on a grounding
point e.g. one of the engine's lifting eyes
(4).
8. Check that the jump lead clamps are
affixed securely so that there are no
sparks during the starting procedure.

Jump starting

9. Start the engine of the "donor car" and
allow it to run a few minutes at a speed
slightly higher than idle
approx. 1500 rpm.
10. Start the engine in the car with the dis-
charged battery.
IMPORTANT
Do not touch the crocodile clips during the
start procedure. There is a risk of sparks
forming.
11. Remove the jump leads in reverse order -
first the black and then the red.
> Make sure that none of the black jump
lead's clamps comes into contact with
the battery's positive terminal or the
clamp connected to the red jump lead!
