Checks
Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at any time (even with the ignition off).
Oil level
The check is carried out either when the ignition is switched on using the oil level indicator in the instrument panel, or using the dipstick.
Engine oil change
Refer to the warranty and maintenance record for details of the interval for this operation. In order to maintain the reliability of the engine and emission control system, the use of additives in the engine oil is prohibited.
Oil specifi cation
The oil must be the correct grade for your engine and conform to the manufacturer's recommendations.
Check all of these levels regularly, in line with the warranty and maintenance record. Top them up if necessary, unless other wise indicated. If a level drops significantly, have the corresponding system checked by a PEUGEOT dealer or a qualified workshop.
Dipstick
There are two marks on the dipstick:
A = maximum If the level is above this mark, contact a PEUGEOT dealer or a qualified workshop. B = minimum Top up the level through the oil filler orifice, using the correct grade of oil for your engine. The level must never be below this mark.
It will only be correct if the vehicle is on level ground and the engine has been off for more than 30 minutes. It is normal to top up the oil level between two services (or oil changes). PEUGEOT recommends that you check the level, and top up if necessary, every 3 000 miles (5 000 kms). After topping up the oil, the check when switching on the ignition with the oil level indicator in the instrument panel is not valid during the 30 minutes after topping up.

Checks
The brake fluid level must be between the marking " A " (MA X A " (MA X Alocated on the remote reservoir) and the marking " B " (MIN located on the main reservoir). If it is not, check the brake pad wear.
Brake fluid level
Changing the fl uid
Refer to the warranty and maintenance record for details of the interval for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations.
Coolant level
The coolant level should be close to the "MA X" mark but should never exceed it.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any work. To avoid any risk of scalding, unscrew the cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and top up the level.
Changing the coolant
The coolant does not have to be replaced at routine services.
Fluid specifi cation
The coolant must conform to the manufacturer's recommendations.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.
When the engine is warm, the temperature of the coolant is regulated by the fan.

Checks
Fluid specifi cation
For optimum cleaning and to avoid freezing, this fluid must not be topped up with or replaced with plain water.
Screenwash and headlamp
wash fluid
In the case of vehicles fitted with headlamp washers, the low fluid level is indicated by an audible signal and a message in the instrument panel screen. Top up the reservoir when you next stop the vehicle.
Avoid prolonged contact of used oil or fluids with the skin.

12 V battery
The battery does not require any maintenance. However, check that the terminals are clean and correctly tightened, particularly in summer and winter.
Refer to the warranty and maintenance record for details of the replacement intervals for these components.
Air filter and passenger compartment filter
Replace the oil filter each time the engine oil is changed. Refer to the warranty and maintenance record for details of the replacement interval for this component.
Oil filter The presence of this label, in particular with the Stop & Start system, indicates the use of a specific 12 V lead-acid battery with special technology and specification. The involvement of a PEUGEOT dealer or a qualified workshop is essential when replacing or disconnecting the battery.
Particle emission filter (Diesel)
The start of saturation of the particle filter is indicated by the temporary illumination of this warning lamp accompanied by a message in the multi-function screen.
As soon as the traffic conditions permit, regenerate the filter by driving at a speed of at least 40 mph (60 km/h) until the warning lamp goes off. If the warning lamp stays on, this indicates a low additive level.
On a new vehicle, the first particle filter regeneration operations may be accompanied by a "burning" smell, which is per fectly normal. 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 on acceleration. This does not affect the behaviour of the vehicle or the environment.
Unless other wise indicated, check these components in accordance with the warranty and maintenance record and according to your engine. Other wise, have them checked by a PEUGEOT dealer or a qualified workshop.
When carrying out work on the battery, refer to the "12 V battery" section for details of the precautions to be taken before disconnecting the battery and following its reconnection.
Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessary . necessary . necessary A clogged passenger compartment filter may have an adverse effect on the per formance of the air conditioning system and generate undesirable odours.

Technical data
Weights and towed loads
The weights are given in the registration certificate for your vehicle and on the manufacturer's VIN plate. The information can also be obtained from PEUGEOT dealers and is included in the descriptive table of technical characteristics for the vehicle in sales brochures. The maximum type-approved trailer weight
varies according to market zone. In each country, you must comply with local legislation on towed loads.
For information on your vehicle's towing capabilities and its gross train weight, contact a PEUGEOT dealer.
Load transfer
If the towing vehicle has not reached the GV W, it is possible to transfer this weight to the trailer. The gross train weight and maximum trailer weight are valid up to an altitude of 1 000 metres; the maximum trailer weight specified must be reduced by 10 % for every additional 1 000 metres of altitude. In all cases, do not exceed the weight of the trailer and the GTW, indicated on your registration certificate. Observe the towing capacities of your vehicle.
The weight of a braked trailer with load transfer can be increased on condition that the equivalent weight is removed from the vehicle and the GTW is not exceeded. High ambient temperatures may result in a reduction in the per formance of the vehicle to protect the engine. If the ambient temperature is above 37 °C, limit the towed load to 700 kg, without any transfer of load. The speed of a towing vehicle must not exceed 60 mph (100 km/h) (comply with the legislation
in force in your country).
The recommended nose weight (weight on the
towbar ball) is 75 kg.
Engines
The values (engine capacity, net maximum power, power to weight ratio, engine speed, CO2 emissions, ...) are given in your vehicle's registration document. They can also be obtained from PEUGEOT dealers and are included in the descriptive table of technical characteristics for the vehicle in sales brochures.
For more information, contact a PEUGEOT dealer or a qualified workshop.
