Citroen C3: Practical information / Checks

Unless otherwise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.

Otherwise, have them checked by a CITROËN dealer or a qualified workshop.

Citroen C3. Checks Only use products recommended by 7 CITROËN or products of equivalent quality and specification.

In order to optimise the operation of components as important as those in the braking system, CITROËN selects and offers very specific products.

12 V battery

Citroen C3. Checks The battery does not require any maintenance.

However, check regularly that the terminals are correctly tightened (versions without quick release terminals) and that the connections are clean.

Citroen C3. Checks For more information on the precautions to take before any work on the 12 V battery, refer to the corresponding section.

Citroen C3. Checks Versions equipped with Stop & Start are fitted with a 12 V lead-acid battery of specific technology and specification. Its replacement should be carried out only by a CITROËN dealer or a qualified workshop.

Passenger compartment filter

Citroen C3. Checks Depending on the environment and the use of the vehicle (e.g. dusty atmosphere, city driving), change it twice as often, if necessary.

Citroen C3. Checks A clogged passenger compartment filter can adversely affect air conditioning system performance and generate undesirable odours.

Air filter

Citroen C3. Checks Depending on the environment and the use of the vehicle (e.g. dusty atmosphere, city driving), change it twice as often, if necessary.

Oil filter

Citroen C3. Checks Change the oil filter each time the engine oil is changed.

Particle filter (Diesel)

Citroen C3. Checks When the particle filter is approaching saturation, this warning lamp comes on temporarily, accompanied by a message warning of the risk of filter clogging.

As soon as the traffic conditions permit, regenerate the filter by driving at a speed of at least 37 mph (60 km/h) until the warning lamp goes off.

Citroen C3. Checks If the warning lamp stays on, this indicates a low Diesel additive level. For more information on Checking levels, refer to the corresponding section.

Citroen C3. Checks Following prolonged operation of the vehicle at very low speed or at idle, you may, in exceptional circumstances, notice the emission of water vapour at the exhaust while accelerating. This has no impact on the vehicle’s behaviour or the environment.

Citroen C3. Checks New vehicle

During the first few particle filter regeneration operations, you may notice a "burning" smell. This is perfectly normal.

Manual gearbox

Citroen C3. Checks The gearbox does not require any maintenance (no oil change).

Automatic gearbox

Citroen C3. Checks The gearbox does not require any maintenance (no oil change).

Brake pads

Citroen C3. Checks Brake wear depends on the style of driving, particularly in the case of vehicles used in town, over short distances. It may be necessary to have the condition of the brakes checked, even between vehicle services.

Unless there is a leak in the circuit, a drop in the brake fluid level indicates that the brake pads are worn.

Citroen C3. Checks 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.

Brake disc wear

Citroen C3. Checks For information on checking brake disc wear, contact a CITROËN dealer or a qualified workshop.

Manual parking brake

Citroen C3. Checks If you notice excessive brake lever travel or decreased effectiveness, the parking brake must be adjusted, even between two services.

This system must be checked by a CITROËN dealer or a qualified workshop.

Wheels and tyres

Citroen C3. Checks The inflation pressure of all tyres, including the spare wheel, must be checked on "cold” tyres.

The pressures indicated on the tyre pressure label are valid for "cold" tyres. If you have driven for more than 10 minutes or more than 6 miles (10 kilometres) at over 31 mph (50 km/h), add 0.3 bar (30 kPa) to the values indicated on the label.

Under-inflation increases fuel consumption. Non-compliant tyre pressure causes premature wear on tyres and has an adverse effect on the vehicle's road holding - risk of an accident!

Driving with worn or damaged tyres reduces the braking and road holding performance of the vehicle. It is recommended to regularly check the condition of the tyres (tread and sidewalls) and wheel rims as well as the presence of the valves. When the wear indicators no longer appear set back from the tread, the depth of the grooves is less than 1.6 mm; it is imperative to replace the tyres.

Using different size wheels and tyres from those specified can affect the lifetime of tyres, wheel rotation, ground clearance, the speedometer reading and have an adverse effect on road holding.

Fitting different tyres on the front and rear axles can cause the ESC to mistime.

    Checking levels

    Check all of the following levels regularly in accordance with the manufacturer's service schedule. Top them up if required, unless otherwise indicated...

    AdBlue® (BlueHDi)

    To respect the environment and ensure compliance with the Euro 6 standard, without adversely affecting the performance or fuel consumption of its Diesel engines, CITROËN has taken the decision to equip its vehicles with a system that associates SCR (Selective Catalytic Reduction) with a Diesel Particle Filter (DPF) for the treatment of exhaust gases...
