NOTE

Cold start capacity^A-

CCA^B(A)

170

If the following instruction is not observed

then the Start/stop function may temporar-

ily cease to work after the connection of an

external battery or battery charger:

If the starter battery has been discharged

so much that the car has no normal electri-

cal functions and the engine is then jump-

started with an external battery or a battery

charger, the Start/stop function may con-

tinue to be activated. If the Start/stop

function then auto-stops the engine shortly

afterwards, there is a great risk that engine

auto-start will fail due to insufficient bat-

tery capacity, because the battery has not

had the time to recharge.

(5.9×3.5×5.1

inches)

Size, L×B×H

The negative battery terminal on the

car's starter battery must never be

used for connecting an external starter

battery or battery charger – only the

car's negative charging point may be

used as the grounding point.

IMPORTANT

If the battery is replaced, make sure you

replace it with a battery with the same

size, cold starting capacity and type as the

original battery (see the decal on the bat-

tery).

If the car has been jump-started, or if there

is insufficient time to charge the battery

with a battery charger, the Start/stop func-

tion is temporarily deactivated until the

battery has been recharged by the car. In

an outside temperature of approx. +15 °C

(approx. 60 °F), the battery needs to be

charged for at least 1 hour by the car. In a

lower outside temperature, the charging

time may increase to 3–4 hours. The rec-

ommendation is to charge the battery

using an external battery charger.

Symbols on the batteries

There are information and warning symbols

on the batteries.

Battery recycle

A used starter battery or support battery

must be recycled in an environmentally sound

manner.

Avoid sparks and naked

flames.

Consult a workshop in the event of uncertainty

about how this type of waste should be dis-

carded - an authorised Volvo workshop is rec-

ommended.

Use protective goggles.

Fuses and central electrical units

Replacing a fuse

Engine compartment

All electrical functions and components are

protected by a number of fuses in order to

protect the car's electrical system from dam-

age by short circuiting or overloading.

•

WARNING

1. Look in the fuse diagram to locate the

fuse.

Fuses in engine compartment (p. 604)

Never use a foreign object or a fuse with an

amperage higher than that specified when

replacing a fuse. This could cause signifi-

cant damage to the electrical system and

possibly lead to fire.

Fuses under the left-hand front seat

(p. 610)

2. Pull out the fuse and check from the side

to see whether the curved wire has blown.

3. If this is the case, replace it with a new

fuse of the same colour and amperage.

If an electrical component or function does not

work, it may be because the component's fuse

was temporarily overloaded and failed. If the

same fuse fails repeatedly then there is a fault

in the circuit. Volvo recommends contacting

an authorised Volvo workshop for checking.

WARNING

Never use a foreign object or a fuse with an

amperage higher than that specified when

replacing a fuse. This could cause signifi-

cant damage to the electrical system and

possibly lead to fire.

Location of central electrical units

WARNING

Contact an authorised Volvo workshop

about the fuses not mentioned in the

owner's manual. If replacing the fuse is not

performed correctly, it can cause serious

damage to the electrical systems.
