A level of coolant that is too low risks

causing major damage to the engine.

Open the cap (2) fig. 315. The coolant

level must be close to the "MAX" mark

without ever going above it.

Engine coolant (Electric version)

The traction system coolant level must

be checked when the motor is cold

and must range between the MIN

and MAX marks on the reservoir. If

the level is under the MIN level, go to

a Fiat Dealership. Do not attempt to

open the cap yourself (fig. 316) to avoid

burns and/or damage to the cooling

system and electronic components.

Topping up and filling operations must

be carried out by qualified personnel at

Fiat Dealership.

If the level is close to or below the

"MIN" mark, it is essential to top it up.

When the engine is hot, the

temperature of the coolant is regulated

by the fan.

F6S0111

Open the cap (3) fig. 317 fill the

reservoir with clean water mixed

with a suitable quantity of approved

windscreen washer fluid which contains

antifreeze.

As the cooling system is pressurised,

wait at least one hour after switching

off the engine before carrying out any

work.

The fluid must be topped up with a

pre-mixed product.

In order to avoid the risk of scalding if

you need to top up in an emergency,

wrap a cloth around the cap and

should be carried out only by a Fiat

Dealership.

Brakes

Depending on the driving style, the

brake wear may vary significantly.The

brake wear may increase when the

vehicle is driven over short distances,

e.g. in the city.

318

F6S0112

It may be necessary to have the

condition of the brakes checked, even

between vehicle services.

The brake fluid level must be between

the MIN and MAX marks.

319

JJ000005_2

If fluid level is below MIN seek the

assistance of a Fiat Dealership.

Unless there is a leak in the circuit, a

drop in the brake fluid level indicates

that the brake pads are worn.

Once new brake linings are installed,

do not brake unnecessarily hard for the

first few journeys.

Batteries do not belong in household

waste. They must be disposed of at an

appropriate recycling collection point.

Laying up the vehicle for more than four

weeks can lead to battery discharge.

Disconnect the clamp from the

negative terminal of the conventional

battery.

Conventional battery

The conventional battery is

maintenance-free provided that the

driving profile allows sufficient charging

of the battery. Short-distance-driving

and frequent engine starts can

discharge the battery. Avoid the use of

unnecessary electrical consumers.

Check regularly that the terminals are

correctly tightened (versions without

quick-release terminals) and that the

connections are clean.

WARNING After washing the vehicle,

moisture, or in wintry conditions, ice

can form on the brake discs and pads:

braking efficiency may be reduced.

Gently dab the brakes to dry and

defrost them.

Ensure the ignition is switched off

before connecting or disconnecting the

conventional battery.

Useful advice for extending the life

of your conventional battery

For information on checking brake disc

wear, contact a Fiat Dealership.

hazard warning lights, etc.) switched on

for a long time when the engine is not

running

WARNING If the charge level remains

under 50% for a long time, the

conventional battery is damaged by

sulphation, reducing its capacity and

efficiency at start-up. The battery is

also more prone to the risk of freezing

(at temperatures of −10 °C/14 °F).

Refer to the "Car inactivity" chapter this

section if the car is left parked for a

long time.

WARNING After setting the ignition

device to STOP and closing the driver's

door, wait at least one minute before

disconnecting the electrical supply

from the conventional battery. When

reconnecting the electrical supply to

the conventional battery, make sure

that the ignition device is in the STOP

position and the driver's door is closed.

before performing any operation on

the electrical system disconnect the

cable from the negative conventional

battery terminal. If, after purchasing

the car, you wish to install electrical

accessories which require permanent

electrical supply (e.g. alarm, etc.)

or accessories which influence the

electrical supply requirements, contact

a Fiat Dealership, whose qualified

staff will evaluate the overall electrical

consumption

WARNING Charging should be slow at

a low ampere rating for approximately

24 hours. Charging for a longer time

may damage the conventional battery.

Replacing the conventional battery

WARNING Any deviation from the

instructions given in this section may

lead to temporary deactivation or

disturbance of the Stop-Start system.

WARNING The cables of the electrical

system must be correctly reconnected

to the conventional battery, i.e. the

positive cable (+) to the positive

terminal and the negative cable (–) to

the negative terminal.

When the conventional battery is being

replaced, please ensure that there are

no open ventilation holes in the vicinity

of the positive terminal. If a ventilation

hole is open in this area, it must be

closed off with a dummy cap, and the

ventilation in the vicinity of the negative

terminal must be opened.

The conventional battery terminals

are marked with the positive (+) and

negative (-) terminal symbols, and are

shown on the cover of the battery itself.
