MAINTENENCE OPERATIONS (Continued)

To maintain the vehicle in good working order, follow these recommendations:

Every 500 km (or during refuelling) check:

  • Engine oil level.
  • Engine coolant level.
  • Clutch/brake fluid level.
  • Tyre pressure.
  • Windscreen and headlight washer liquid.

Engine oil and filter

These should be replaced at the specified mileage. Change once a year if the mileage limits are not reached.

Air filter

When the vehicle is regularly driven on dusty roads, the air filter should be checked more regularly than specified.

Brake pads

On some models, worn brake pads are signalled by a warning light on the instrument panel.

For vehicles equipped with front brake pad wear detectors only, rear brake pads should also be checked when the front ones are replaced.

The rear pads however may not need replacing due to their function on the vehicle but should be checked at a later date.

Brake/clutch fluid

The brake fluid is hygroscopic, ie, it absorbs humidity. To avoid braking defects, the brake fluid must be replaced periodically, regardless of the mileage covered, depending on the type of vehicle.

Battery

The electrolyte level should be checked regularly during warm weather.

Air conditioning (if fitted)

The condition of the air filter (if fitted) on the evaporator should be checked once a year by the Alfa Romeo Assistance Network, preferably just before the summer. (It should be checked more frequently if the vehicle is regularly driven on dusty roads).

Antifreeze

In order to conserve the protective characteristics of the mixture, it is advisable to top-up the anti-freeze level with Alfa Romeo Concentrated Antifreeze.

Note

During abnormal use of the vehicle (eg. on roads covered with salt and/or corrosive substances, on bumpy roads etc.) the drive shafts and steering box boots, the cleanliness and lubrication of the articulation points and the hinges, doors, bonnet and boot lid locks etc. should be checked frequently.

If it becomes necessary (in an emergency) to use fuel, lubricants, and/or fluids in general which do not meet the manufacturer's requirements, both the fluids and relative filters should be replaced as soon as possible.
