2023 Land Rover Defender Fuel and Refueling

SAFETY PRECAUTIONS

Make sure that the following warnings have been read and understood. Failure to observe the warnings could result in an accident, leading to serious injury or death.

WARNING

Do not smoke, use an exposed flame, or cause sparks while refueling.
Avoid exposing the fuel gases to any potential sources of ignition.
Switch off the engine when refueling, as it is both a source of extreme temperatures and electrical sparks.
When refueling, switch off any personal electronic devices such as mobile phones or music players.
Take note of all warnings and instructions given on the label affixed to the inside of the fuel filler flap.
The fuel system is designed to make sure that spillage does not occur. Do not attempt to fill the tank past its maximum capacity.
Make sure that the fuel filler nozzle is fully inserted into the filler neck. If the nozzle is inserted loosely, fuel spillage may occur.
When refueling, make sure that all of the windows, doors, and panoramic roof are fully closed. Use extreme care and caution if young children or animals are in the vehicle.
Only use containers specifically designed for carrying fuel, and always remove them from the vehicle to fill them.

PETROL ENGINED VEHICLES

CAUTION
Use high-quality fuel with a detergent that meets the specification defined by EN228, WWFC5 cat. 5, or the national equivalent. Low-quality fuel can damage the engine and reduce engine performance.

CAUTION
Do not use leaded fuels, fuels with lead substitutes, e.g., manganese-based, or fuel additives. The vehicle’s emission control systems can be adversely affected, which may affect the vehicle’s warranty coverage.

CAUTION
Fuel system cleaning agents should not be used, unless approved by the vehicle manufacturer. Inadequate cleaning agents may damage the fuel system.

OCTANE RATING

CAUTION
Do not use fuels with an octane rating lower than 91 RON, as severe engine damage may occur.

CAUTION
Do not use leaded fuels, fuels with lead substitutes, e.g., manganese-based or fuel additives. Doing so may adversely affect the vehicle’s emission control systems and affect the vehicle’s warranty.

The vehicle manufacturer recommends the use of premium unleaded fuel with a minimum octane rating of 95 RON. Using the correct fuel specification helps to maintain the vehicle’s performance, fuel economy, and driveability.

If premium unleaded fuel is not available, use unleaded fuel with a lower octane rating, down to a minimum of 91 RON. Using lower octane-rated fuel may reduce the engine’s performance, increase fuel consumption, cause an audible engine knock, and cause other driveability problems.

Consult a retailer/authorized repairer if an engine knock is detected while holding a steady speed on level roads. Also consult a retailer/authorized repairer if a heavy persistent engine knock is detected, even if using fuel to the recommended octane rating. Failure to do so is a misuse of the vehicle, which is not covered by the vehicle’s warranty.

NOTES
An occasional, light engine knock when accelerating or climbing hills is acceptable.

Super Green Plus 98 RON unleaded fuel, where available, may be used as an alternative to the standard 95 RON unleaded fuel.

ETHANOL

CAUTION
Do not use fuels containing more than 10% ethanol. Higher ethanol content can damage the vehicle’s engine and fuel system.

CAUTION
Do not use E85 fuels with 85% ethanol content, as serious engine and fuel system damage can occur.

Fuels containing up to 10% ethanol may be used, e.g., E5 and E10.

Make sure that the fuel has octane ratings no lower than those recommended for unleaded fuel. Correct engine operation should not be affected with fuel containing the permissible amount of ethanol. If a difference is detected, the use of conventional unleaded fuel should be resumed.

METHANOL

CAUTION
Wherever possible, avoid using fuel containing methanol. Using fuel containing methanol may cause serious engine and fuel system damage, which is not covered by the vehicle’s warranty.

METHYL TERTIARY BUTYL ETHER (MTBE)

Unleaded fuel containing an oxygenate known as Methyl Tertiary Butyl Ether (MTBE) can be used. The ratio of MTBE to conventional fuel must not exceed 15%. MTBE is an ether-based compound derived from petroleum. MTBE has been specified by several refiners as a substance to enhance the octane rating of fuel.

DIESEL ENGINED VEHICLES

CAUTION
If the fuel tank is inadvertently filled with petrol instead of diesel, do not attempt to start the engine. In this event, contact a retailer/authorized repairer immediately. Inadequate fuels may damage the fuel system and engine components.

NOTES
Any damage caused by running the vehicle with fuel other than that stipulated is not covered under the warranty.

NOTES
If a diesel engine is difficult to start in extremely cold temperatures of -15°C or less, consult a retailer/authorized repairer for assistance.

Use only high-quality diesel fuel, according to the European standard EN590:2013+A1:2017, WWFC 5 cat. 5 or equivalent.

CAUTION
Fuels containing a blend of up to 7% bio-diesel may be used, in accordance with the European standard EN590:2013+A1:2017. Using a higher blend of biodiesel is not recommended. Inadequate fuels may damage the fuel system and engine components, or premature fuel filter blockage may occur.

NOTES
Malaysia only: Fuels containing a blend of up to 30% bio-diesel may be used.

The quality and specification of diesel fuel vary significantly, depending on geographical location. Using premium fuel is recommended, or the highest quality of fuel available. High-quality fuel promotes a longer life for the engine’s components.

CAUTION
Lower grade fuel contains higher levels of sulfur, which is detrimental to the engine’s components. If low-quality fuel is used, light-colored smoke may be evident at the exhaust.

Prolonged use of additives is not recommended. Do not add paraffin or petrol to diesel fuels.

AUXILIARY HEATER

WARNING
Do not operate the auxiliary heater when refueling the vehicle. Doing so may cause fuel vapors to combust, potentially causing a fire or explosion.

The auxiliary heater is powered by fuel drawn from the vehicle’s tank and operates at low ambient temperatures, helping to boost the temperature of the engine’s coolant. See AUXILIARY HEATER.

SULPHUR CONTENT

CAUTION
Using an incorrect specification of fuel causes serious damage to the engine and the exhaust after-treatment system. The vehicle’s warranty does not cover this. If in doubt, contact a retailer or authorized repairer for advice.

CAUTION
The maximum sulfur content of the diesel fuel must not exceed the level shown in the table below. The sulfur content is in compliance with the EN590-EU4 and World Wide Fuel Charter (WWFC Category 3 or above) standards. Failure to comply with the standards may damage engine components and the exhaust after-treatment system.

Vehicle emission level	Maximum sulfur content % (parts per million)
EU6	0.0015 (15)
EU5 and lower	0.005 (50)

NOTES
If in doubt regarding the emissions level of the vehicle, contact a retailer or authorized repairer for advice.

DIESEL EXHAUST FLUID (DEF)

WARNING
DEF must be kept out of children’s reach, to avoid serious injury or death.

WARNING
Read the label for safety precautions when using DEF, to avoid injury.

CAUTION
DEF must be stored in the original container, in a cool, dry, and well-ventilated area. Observe the manufacturer’s storage and handling recommendations. If inappropriately stored, DEF may spill or be exposed to contamination.

CAUTION
DEF has a strong odor and can stain clothing or upholstery. Take care not to spill the fluid when performing a top-up procedure. In the event of spillage, rinse immediately with clean water.

CAUTION
When refilling, make sure that the correct specification of DEF is used. Use of the incorrect fluid can result in serious damage to the vehicle. In this situation, do not start the engine, contact a retailer/authorized repairer immediately.

Vehicles with a diesel engine may have a tank containing Diesel Exhaust Fluid (DEF). DEF is used to make sure that correct exhaust emissions are achieved. DEF is also known as AdBlue™, AUS 32, and ARLA 32. AdBlue™ is a trademark of the Verband der Automobilindustrie e.V. (VDA).

Dependent on the current geographical location, correct use of the DEF system may be a legal requirement. Running the vehicle without the correct specification of DEF may be a criminal offense. Always use the correct DEF specification, and the correct quantity of DEF. See LUBRICANTS AND FLUIDS and CAPACITIES.

The consumption of DEF can vary greatly. An average consumption rate can be 800 km (500 miles) / 1 L. However, this consumption rate can be more than doubled, depending on driving style, and road and weather conditions.

The distance until the DEF tank is empty and the volume of DEF required for refill is displayed via the Touchscreen:

Touch the settings icon¹ from any screen.
Touch the ALL soft key.
Touch the Vehicle’s soft key.
Touch the Service soft key.
The DEF range and refill volume is displayed.
Touch the exit icon² to return to the previously displayed screen.

The instrument panel displays a series of messages when the DEF level becomes low. The volume of DEF required for refill also accompanies each message:

The first message is accompanied by a white warning icon, indicating low DEF level, and the distance remaining until the DEF tank is empty.
The second message is accompanied by a yellow warning icon, indicating low DEF level, and the distance remaining until the DEF tank is empty.
The third message is accompanied by a yellow warning icon, and starts a countdown of the distance remaining until the DEF tank is empty. After the countdown, vehicle start is inhibited.
The final message is accompanied by a red warning icon and is displayed when the distance remaining is zero. The message states that no further restarts are possible until DEF is added to the tank.

NOTES
When the DEF level becomes low, a notification displays in the instrument panel. Refill the DEF tank at the earliest opportunity.

The volume of DEF required to top up or restart the engine is displayed in the instrument panel. Refill bottles are available from a retailer/authorized repairer.

To perform a DEF top-up procedure, locate the DEF tank. See FLUID FILLER LOCATIONS. Then, follow the steps below:

Turn the tank filler cap counter-clockwise to remove.
Making sure not to exceed the required volume, top up the tank following the instructions given on the DEF container.
NOTES
Non-drip bottles are the recommended method for top-up.
Replace the tank filler cap and continually turn clockwise until hand tight.

If a DEF warning lamp, or message illuminates with a red warning icon, seek qualified assistance at the earliest opportunity. The possible events for this include DEF system malfunctions, incorrect fluid, and poor fluid quality. See DIESEL EXHAUST FLUID (DEF) (RED) and DIESEL EXHAUST FLUID (DEF) (YELLOW).

NOTES
In extremely low temperatures below -10°C, DEF may freeze in the tank, making refilling difficult. Move the vehicle into a warmer environment, e.g., a garage. Raise the ambient temperature, in order to thaw the DEF, before attempting to top up. In these conditions, it may take up to 1 hour of driving before the low DEF message extinguishes.

NOTES
When starting and stopping the engine, operation of the DEF pumps may be heard, but this is no cause for concern.

NOTES

The check engine warning lamp may illuminate after a refill. In this event, start the engine, run for approximately 30 seconds, and then switch off the engine. Do this three times in succession. See CHECK ENGINE (YELLOW).
