2015 VOLKSWAGEN EOS Owners Manual

NOTICE
x Do not start the engine if the engine oil level is above range (A). Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Otherwise the catalytic converter and engine can be damaged!
x When changing or topping off fluids, make sure that you pour the fluids into the correct reservoirs. Adding the wrong type of operating fluids will cause serious malfunctions and engine damage.
The engine oil level should never be above range (A). Otherwise oil can be drawn in by the crankcase ventilation system and enter the atmosphere via the exhaust system.
Engine oil consumption

Changing oil at regular intervals is very important because the lubricating properties of oil decrease gradually during normal vehicle use. If you are not sure when to have the oil changed, ask your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Sometimes, engine oil should be changed more often than specified for normal use. Change oil more frequently if you often drive short distances, in dusty areas or in stop-and-go traffic, or if you use your vehicle where temperatures stay below freezing for long periods.
Volkswagen recommends that you 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.
Detergent additives in the oil will make fresh oil look dark after the engine has been running a short time. This is normal and no reason to change engine oil more often.
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 before 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 containers 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.

Engine coolant

Flashes
Temperature gauge needle
⇒ fig. 154
Possible cause Proper response
(B) Normal range Engine coolant level too low.
Check the engine coolant level after the engine has cooled down and add engine coolant if low If the engine coolant level is correct or the problem continues after adding coolant, do not drive any farther. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility. These instructions apply only when the coolant temperature stays in the normal range. Stop immediately if the needle goes into the red warning zone (C).
– Engine coolant system malfunction.

To protect the engine, the mixture must always contain at least 40% coolant additive even in warm weather or climates where antifreeze protection is not needed.
If more antifreeze protection is needed for climate conditions, the percentage of coolant additive can be increased. However, the coolant additive percentage must never be more than 60%; otherwise, antifreeze protection is reduced and the ability of the mixture to cool the engine is also reduced.
When adding engine coolant, use a mixture of distilled water and at least 40% coolant additive G 13
or G 12 plus-plus (TL-VW 774 G) for optimum corrosion protection ⇒ .
Do not mix G 13 with G 12 plus or G 11. Mixing these coolant additives together significantly reduces
corrosion protection ⇒  and can lead to engine damage that is not covered by any Volkswagen Limited Warranty.
WARNING
Too little antifreeze protection in the engine cooling system can cause engine failure and severe injuries.
x Always make sure there is enough of the correct coolant additive to provide proper antifreeze protection at the coldest temperatures that can be expected where the vehicle will be used.
x At extremely cold temperatures, the coolant could freeze, causing the vehicle to break down. The heater would also not work, and vehicle occupants could be without protection at subfreezing temperatures.
NOTICE
Never mix original Volkswagen engine coolant additives with other additives not approved by Volkswagen. Mixing Volkswagen coolant additives with coolant additives made by other manufacturers can seriously damage the engine and the engine cooling system.
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 operating fluids and dispose of them properly in accordance with applicable environmental laws and regulations.

Checking engine coolant level and topping off

Fig. 156 Coolant expansion tank cap in the engine compartment.

x Carefully unscrew the cap ⇒ .
x Add only new engine coolant according to Volkswagen specifications (⇒ Engine coolant
specifications) ⇒ .
x The engine coolant level must be inside the marks on the side of the reservoir ⇒ fig. 155. 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 meeting
Volkswagen specifications (⇒ Engine coolant specifications) is unavailable! 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 components 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) (automatic) or Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, 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 authorized 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. 155. Excess engine coolant may be forced out of the engine cooling system when it gets hot and cause damage.
