To provide effective lubrication and cooling for internal engine parts, all internal combustion engines use some oil. Oil consumption varies from engine to engine and may change over the life of the en-gine. Engines tend to use more oil during the break-in period than they do afterward, when oil con-sumption has stabilized.
Under normal conditions, the rate of oil consumption depends on oil quality as well as viscosity, engine speed (rpm), outside temperature, road conditions, the amount of oil dilution caused by condensed water or fuel residue, and oxidation of the oil. Oil consumption may increase with engine wear over time, until replacement of worn engine parts may become necessary.
Volkswagen recommends that you to check the engine oil level at regular intervals, preferably every time you fill the fuel tank, and always before a long trip. Your vehicle may consume engine oil depend-ing on several variables. A maximum of 1 quart per 1200 miles (1 liter per 2000 km) would be consid-ered normal. New vehicles may consume more oil over the first 3000 miles (5000 km).
The oil pressure warning light is not an indicator of low engine oil level. If the warning light stays on or flashes while driving (above 1500 rpm), a chime will sound. It indicates that the oil pressure is too low. Stop the engine immediately, check the engine oil level and add oil if necessary. If the engine oil level is normal, but the light continues to flash, do not keep driving or let the engine idle, as damage may occur.
If you believe your engine uses too much oil, we recommend that you consult your authorized Volkswagen dealer or authorized Volkswagen Service Facility so that the cause of your concern can be properly diagnosed. Please keep in mind that accurate measurement of oil consumption requires great care and may take some time. Your authorized Volkswagen dealer and authorized Volkswagen Service Facility have instructions for how to measure oil consumption accurately.
Depending on the way the vehicle is driven and the operating conditions, oil consumption can be up to 1 quart per 1200 miles (0.5 liter per 1000 km). Consumption may be higher for new vehicles during the first 3000 miles (5000 km).
Changing engine oil

Page 312 of 398


WARNING
If you must change the engine oil yourself, be sure to take the following precautions:
x Always wear eye protection.
x To reduce the risk of burns from hot engine oil, let the engine cool down completely be-fore beginning.
x When removing the oil drain plug with your fingers, stay as far away as possible. Always keep your forearm parallel to the ground to help prevent hot oil from running down your arm.
x Drain the oil into a container designed for this purpose, one large enough to hold at least the total amount of oil in your engine.
x To reduce the risk of poisoning, never drain the oil into empty food or beverage contain-ers that might mislead someone into drinking from them.
x Engine oil is poisonous and must be stored out of the reach of children.
x Continuous contact with used engine oil is harmful to your skin. Always protect your skin by washing thoroughly with soap and water.
Before changing the oil, first make sure you know where you can properly dispose of the old oil.
Dispose of the old oil an environmentally-responsible manner. Never dump the old oil on garden soil, in wooded areas, in the street, into streams, rivers, or bodies of water, or down sewage drains.
Recycle used oil by taking it to a collection facility for used engine oil in your area, or contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Volkswagen recommends that you always have your oil and oil filter changed by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. They have the required expertise and special tools and will dispose of the old oil properly.

WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
Engine coolant specifications

Page 318 of 398


x If the fluid in the engine coolant reservoir is any color but pink, then G 13 was mixed with a different engine coolant. If this is the case, the engine coolant must be replaced immediately. Otherwise serious malfunctions or engine damage can occur!
Engine coolant and engine coolant additives can pollute the environment. Collect leaking operat-ing fluids and dispose of them properly in accordance with applicable environmental laws and regula-tions.

Checking engine coolant level
x When the engine is cold, check the engine coolant level relative to the marking on the side of the
expansion tank ⇒ fig. 152.
x If the coolant level in the tank is below the minimum mark (“min”), add coolant. When the engine is warm, the engine coolant level may be slightly above the upper edge of the marked range.
Adding engine coolant
x Always protect face, hands, and arms from hot escaping coolant or steam by covering the cap with a large, thick rag.
x Carefully unscrew the cap ⇒ .
x Add only new engine coolant according to Volkswagen specifications (⇒Engine coolant specifica-
tions) ⇒ .
x The engine coolant level must be inside the marks on the side of the reservoir ⇒ fig. 152. Do not
fill above the top edge of the filling range! ⇒ 
x Screw the lid tightly.
x Even in an emergency, do not use any other kind of coolant additive if engine coolant that meets
Volkswagen specifications (⇒ Engine coolant specifications) is not available! Instead, add distilled
water only ⇒ . As soon as possible, have the correct coolant ratio restored using engine coolant
that meets Volkswagen specifications ⇒  Engine coolant specifications.
WARNING
Hot steam and hot engine coolant can cause serious burns.
x Never open the hood if you see steam or coolant escaping from the engine compartment. Always wait until you no longer see or hear steam or coolant escaping from the engine.
x Always let the engine cool down completely before carefully opening the hood. Hot com-ponents will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P).
– Take the vehicle key out of the ignition.
– On vehicles with push-button start, make sure that the remote control vehicle key is out of range of the vehicle and that the vehicle cannot be started by depressing the starter
button ⇒  Starter button.
– Always keep children and others away from the engine compartment and never leave them unsupervised.
x The engine coolant system is under pressure when the engine is hot. Never unscrew the coolant expansion tank cap when the engine is hot. Hot coolant can spray out and cause severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclockwise direction while applying light downward pressure on the top of the cap.
– Always protect your face, hands, and arms from hot escaping coolant or steam by covering the cap with a large, thick rag.
x Never spill fluids on the engine or exhaust system when refilling. Spilling fluids onto hot parts of the engine or exhaust system can cause a fire. Under some conditions, the ethylene glycol in engine coolant can catch fire.

NOTICE
x Use distilled water only when adding coolant! All other types of water contain chemical compounds that can cause extensive corrosion damage to the engine. This can even lead to engine failure. If you have added non-distilled water, take the vehicle immediately to an author-ized Volkswagen dealer or an authorized Volkswagen Service Facility to have the coolant system drained, flushed, and refilled completely with the proper coolant.
x Refill engine coolant only up to the top edge of the marked fill range ⇒ fig. 152. Excess engine coolant may be forced out of the engine cooling system when it gets hot and cause damage.
x In the case of significant engine coolant loss, refill engine coolant only when the engine is completely cooled down. Significant engine coolant loss is a sign of leaks in the cooling sys-tem. Have the engine cooling system checked immediately by an authorized Volkswagen deal-er or an authorized Volkswagen Service Facility. Otherwise the engine may be damaged!
x When changing or topping off operating fluids, make sure that you pour the fluids into the correct reservoirs. Serious malfunctions and engine damage can result if you pour operating fluids into the wrong reservoir.
