2015 VOLKSWAGEN JETTA engine

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.

Engine coolant

The following information applies to vehicles without an engine coolant temperature gauge. If your
vehicle is equipped with an engine coolant temperature gauge in the instrument cluster, see ⇒  Warn-ing light and engine coolant temperature gauge.
When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.
The following table explains what to do if the engine coolant temperature warning light ~ does not go out a few seconds after the engine is started or starts flashing while driving.

Flashes Possible cause Proper response
~
Engine coolant temperature too high.

NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.

Engine coolant specifications

Checking engine coolant level and topping off

Fig. 167 Coolant expansion tank in the engine compartment.

Fig. 168 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 specifica-
tions) ⇒ .
x The engine coolant level must be inside the marks on the side of the reservoir ⇒ fig. 167. 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) (automatic) or Neutral (manual only).
– 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. 167. Excess engine coolant may be forced out of the engine cooling system when it gets hot and cause damage.
