Renault Boreal
Petrol and flex versions
Useable fuel tank capacity:
- Approximately 50 litres.
With the vehicle unlocked, to open the fuel filler flap A, press zone B and release it. Open and unscrew the fuel tank cap 1.
There is a cap holder 2 on the fuel tank flap to hold the cap during fuelling.
To close it, press on the fuel filler flap A by hand, as far as it will go. Depending on the vehicle, cover 1 is connected to the vehicle by a plastic cable. For details on filling the fuel tank, refer to the information on "Filling with fuel".
warning
The fuel filler cap is specifically designed for your vehicle. If you have to replace it, make sure it is identical to the original cap model. Contact an approved Dealer.
Never place the cap near a source of heat or flame.
Do not wash the filler area with a high pressure washer.
Fuel grade
flex versions (petrol and ethanol)
Engines with a Flex system (petrol and ethanol) can run on a mixture of petrol and ethanol in any proportion (hydrous ethanol and/or unleaded petrol).
When changing fuel from petrol to ethanol and vice versa, remember that the fuel injection system takes several miles to adapt to the new fuel supply.
It is essential to use unleaded petrol. The octane rating (RON) must match the information shown on the fuel filler flap A.
warning
Flex (petrol and ethanol) vehicles use only type-C petrol, premium petrol or ethanol.
For journeys out of the country, do not fill up in any circumstances with leaded petrol or pure petrol with an octane rating less than 95.
Petrol versions
It is essential to use unleaded petrol. The octane rating (RON) must match the information shown on the fuel filler flap A.
warning
Persistent smell of fuel
If there is a persistent smell of fuel, stop the vehicle when traffic conditions allow and switch off the ignition. Switch on the hazard warning lights and ask your passengers to leave the vehicle and to keep away from traffic. Please contact an authorised dealer.
warning
For the fuel gauge to display correctly after refuelling, perform the operation with the ignition off and add at least 2.20 gal (10 litres) of fuel.
warning
Any intervention and/or modification of the fuel supply system is strictly prohibited (electronic unit, wiring, fuel circuit, injector, protective covers, etc.) as this may be dangerous (unless undertaken by qualified Network personnel).
warning
The engine may be hot when working in close proximity. In addition, the engine cooling fan can come on at any moment. The symbol
in the engine compartment reminds you of this.
Risk of injury.
Filling with fuel
With the ignition off, insert the nozzle to fill the fuel tank (avoid the risk of splashing).
Keep the nozzle in this position throughout the entire filling operation. When the pump cuts out automatically at the end of the filling procedure, a maximum of two further filling attempts may be made, as there must be sufficient space in the fuel tank to allow for expansion.
Make sure that no water enters the fuel tank during filling.
After filling, refit the cap 1 and close the filler flap A to avoid any water or foreign bodies from entering the system.
Always make sure that the cap 1, the flap A and its perimeter remain clean and free of dust, mud, dirt, etc.
Special case
When the vehicle has been stopped for around three months, you must add fuel to prevent damage to the fuel pump.
To do this, with the ignition off, fill up with fuel or add at least approximately 2.20 gallons (10 litres), then start the engine to operate the pump and renew the fuel in the circuit.
If it is not possible to add at least 1.10 gallons (5 litres) of fuel due to the fuel level in the tank, drive the vehicle until the tank has capacity.
Petrol version
Using leaded petrol will damage the antipollution system and may lead to a loss of warranty.
To ensure that the fuel tank is not filled with leaded petrol, the fuel tank filler neck contains a restrictor fitted with a foolproof system which only allows the nozzle for unleaded petrol to be used (at the pump).
warning
Persistent smell of fuel
If you notice a persistent fuel odour you should:
- stop the vehicle when traffic conditions allow it and switch off the ignition;
- switch on the hazard warning lights and ask your passengers to leave the vehicle and stay clear of the traffic;
- contact an authorised dealer.
