STARTING AND DRIVING

lower temperature or Transmission hot

Stop safely, wait for cooling. Follow the

recommendation given, reduce speed or

stop the car in a safe way and allow the

engine to run at idling speed for several

minutes to enable the gearbox to cool

down.

Overheating in the engine and

drive system

Under certain conditions, e.g. hard driving in

hilly terrain and hot climate, there is a risk

that the engine and drive system may over-

heat – in particular with a heavy load.

Symbols in the driver display

Symbol Specification

High engine temperature. Follow

the recommendation given.

In the event of overheating, the engine's

power may be limited temporarily.

•

Low level, coolant. Follow the

recommendation given.

If the car overheats, the air conditioning

may be switched off temporarily.

•

Remove any auxiliary lamps from in front

of the grille when driving in hot climates.

Do not turn the engine off immediately

you stop after a hard drive.

If the temperature in the engine's cooling

system becomes too high then a warning

symbol is illuminated and the driver dis-

play shows the message Engine

Follow the recommendation

given.

NOTE

It is normal for the engine's cooling fan to

operate for a time after the engine has

been switched off.

clamps to the donor battery's positive ter-

minal (1).

The electrical functions in the car load the

starter battery to varying degrees. Avoid

using the ignition position II when the car is

switched off. Instead, use ignition position I -

which uses less power.

Also, be aware of different accessories that

load the electrical system. Do not use func-

tions which use a lot of power when the car is

switched off. Examples of such functions are:

IMPORTANT

Connect the start cable carefully to avoid

short circuits with other components in the

engine compartment.

5. Open the positive jump-starting point's

cover (2).

ventilation fan

•

headlamps

6. Connect the red jump lead's other clamp

onto the car's positive jump-starting point

(2).

windscreen wiper

audio system (high volume).

7. Connect one of the black jump lead's

clamps to the donor battery's negative ter-

minal (3).

If the starter battery voltage is low, a message

is shown in the driver display. The energy-sav-

ing function then shuts down certain functions

or reduces certain functions such as the venti-

lation fan and/or audio system.

Attachment points for the jump leads.

When jump starting the car, the following

steps are recommended to avoid short circuits

or other damage:

8. Connect the black jump lead's other

clamp onto the car's negative jump-star-

ting point (4).

In which case, charge the starter battery

by starting the car and then running it for

at least 15 minutes - starter battery charg-

ing is more effective during driving than

running the engine at idling speed while

stationary.

9. Check that the jump lead clamps are

affixed securely so that there are no sparks

during the starting attempt.

position 0.

2. Check that the donor battery has a voltage

of 12 V.

10. 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.

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.

WARNING

charged battery.

High voltage can be dangerous in the event

of incorrect intervention. Do not touch any-

thing on the batteries that is not clearly

described in the owner's manual.

The battery can generate oxyhydrogen

gas, which is highly explosive. A spark

can be formed if a jump lead is con-

nected incorrectly, and this can be

enough for the battery to explode.

•

IMPORTANT

Do not touch the connections between

cable and car during the starting attempt.

There is a risk of sparks forming.

48 V support battery must never be

used for jump-starting.

•

Do not connect the jump leads to any

fuel system component or any moving

part. Be careful of hot engine parts.

External electrical equipment must not,

under any circumstances, be con-

nected to the 48 V battery.

•

12. Remove the jump leads in reverse order -

first the black and then the red.

The battery contains sulphuric acid,

which can cause serious burns.

•

The 48 V battery may only be serviced

and replaced by a workshop – an

authorised Volvo workshop is recom-

mended.

Make sure that none of the black jump

lead's clamps comes into contact with the

car's positive jump-starting point/donor

battery's positive terminal or the clamp

connected to the red jump lead.

•

If sulphuric acid comes into contact

with eyes, skin or clothing, flush with

large quantities of water. If acid

splashes into the eyes - seek medical

attention immediately.

Never smoke near the battery.
