Engine oil level
• Make sure that your car is on level ground.
• Check the oil level before the car is driven, or at least 5 minutes after the engine has been switched off.
If the oil is checked immediately after driving the vehicle, some of the oil will remain in the upper engine components, resulting in an inaccurate reading on the dipstick.
The correct oil
Modern engines place great demands on their oil. It is very important that the correct oil for your car is used
|Engine oil grade
||Multigrade engine oil, viscosity SAE 5W/30 to ACEA B1/B3 Land Rover specification WSS-M2C-913B
• If you have to add oil frequently, you should check whether you have any oil leaks. Place some clean paper under the car overnight, and check for stains in the morning. If there are no leaks, the engine may be burning oil, or the oil may only be leaking when the engine is running.
• Always maintain the level between the upper and lower dipstick marks (see photo 3). If the level is too low severe engine damage may occur. Oil seal failure may result if the engine is overfilled by adding too much oil.
The dipstick top is often brightly-coloured for easy identification (see Underbonnet check points for exact location). Withdraw the dipstick.
Using a clean rag or paper towel remove all oil from the dipstick. Insert the clean dipstick into the tube as far as it will go, then withdraw it again.
Note the oil level on the end of the dipstick, which should be between the upper full mark (1) and low minimum mark(2). Approximately 1.75 litres of oil will raise the level from the lower mark to the upper mark.
Oil is added through the filler cap. Unscrew the cap and top-up the level; a funnel may help to reduce spillage.
Add the oil slowly, checking the level on the dipstick often. Don’t overfill (see Car care).

DO NOT attempt to remove the expansion tank pressure cap when the engine is hot, as there is a very great risk of scalding. Do not leave open containers of coolant about, as it is poisonous.
• With a sealed-type cooling system, adding coolant should not be necessary on a regular basis. If frequent topping-up is required, it is likely there is a leak. Check the radiator, all hoses and joint faces for signs of staining or wetness, and rectify as necessary.
• It is important that antifreeze is used in the cooling system all year round, not just during the winter months. Don’t top-up with water alone, as the antifreeze will become too diluted.
||Ethylene glycol based antifreeze with OATS corrosion inhibitors
The coolant level is indicated by a fill level line on the side of the expansion tank on the left-hand side of the engine compartment.
If topping-up is necessary, wait until the engine is cold. Slowly remove the expansion tank cap to release any pressure present in the cooling system, and remove it.
Add a mixture of water and antifreeze to the expansion tank until the surface of the coolant is level with the mark on the expansion tank. Refit the cap securely.

Brake (and clutch) fluid level
Brake fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling and pouring it.
Do not use fluid that has been standing open for some time, as it absorbs moisture from the air, which can cause a dangerous loss of braking effectiveness.
The fluid level in the reservoir will drop slightly as the brake pads wear down, but the fluid level must never be allowed to drop below the MIN mark.
Before you start
• Make sure that your car is on level ground.
• If the reservoir requires repeated topping-up this is an indication of a fluid leak somewhere in the system, which should be investigated immediately.
• If a leak is suspected, the car should not be driven until the braking system has been checked. Never take any risks where brakes are concerned.
Release the clips and remove the plastic cover from the right-hand side of the engine compartment.
The MAX and MIN marks are indicated on the side of the reservoir. The fluid level must be kept between the marks at all times.
If topping-up is necessary, first wipe clean the area around the filler cap to prevent dirt entering the hydraulic system.
Disconnect the level sensor wiring plug, then unscrew the reservoir cap and carefully lift it out of position,taking care not to damage the level switch float. Inspect the reservoir, if the fluid is dirty the hydraulic system should be drained and refilled.
Carefully add fluid taking care not to spill it onto the surrounding components. Use only DOT 4 fluid; mixing different types can cause damage to the system. After topping-up to the correct level, securely refit the cap and wipe off any spilt fluid.
Power steering fluid level
• Park the vehicle on level ground.
• Set the steering wheel straight-ahead.
• The engine should be turned off, and the fluid cool.
For the check to be accurate, the steering must not be turned while the level is being checked.
• The need for frequent topping-up indicates a leak, which should be investigated immediately.
The reservoir is located on the left-hand side of the engine compartment. The minimum and maximum levels are indicated by marks on the side of the reservoir. The fluid level should be between MIN and MAX.
If topping-up is required, wipe clean the area around the reservoir filler neck(s) and unscrew the filler cap(s)from the reservoir.
When topping-up, use Texaco 14315 Cold Climate PAS fluid and do not overfill the reservoir. When the level is correct,securely refit the cap(s).
Screen washer fluid level
• Screenwash additives not only keep the windscreen clean during foul weather, they also prevent the washer system freezing in cold weather – which is when you are likely to need it most. Don’t top-up using plain water as the screenwash will become too diluted, and will freeze during cold weather.
On no account use coolant antifreeze in the washer system – this could discolour or damage paintwork.
The screen washer fluid reservoir is located in the front, left-hand corner of the engine compartment. If necessary, remove up the cap.
When topping-up, add a screenwash additive in the quantities recommended by the manufacturer.
It could also be time to replace the wiper blades. For details, click below
Check the condition of the wiper blades; if they are cracked or show any signs of deterioration, or if the glass swept area is smeared, renew them. Wiper blades should be renewed annually.
To remove a front wiper blade, pull the arm away from the screen, squeeze together the sides and pivot the cover upwards.
Press apart the clips and slide the blade from the arm.
To remove a rear wiper blade, pull the arm away from the screen, use a screwdriver to depress the tab, and slide the blade from the arm.
