2017 VOLKSWAGEN TIGUAN engine coolant

Coolant and coolant additives can pollute the environment. Spilt service fluids must be
collected then disposed of properly and in an environmentally responsible way.
Checking the coolant level and refilling coolant

First read and observe the introductoryinformation and safety warnings⇒
Introduction
The warning lamp for the engine coolant will light up if the engine coolant level is too low.
Preparation
•Park the vehicle on a firm and level surface.
•Allow the engine to cool down ⇒.
•Open the bonnet ⇒ In the engine compartment.
•The coolant expansion tank is identified by the symbol on the cap ⇒ Fig. 230.
Checking the coolant level
•When the engine is cold, check the coolant level on the side markings of the engine coolant
expansion tank ⇒ Fig. 229. The engine coolant level must be between the marks.
•Refill coolant if the liquid level in the coolant expansion tank is below the minimum marking
(min). When the engine is warm, the engine coolant level may be slightly above the maximum
(MAX) mark.
Refilling coolant
•Always protect your face, hands and arms from hot coolant or steam by placing a suitable cloth
on the cap of the coolant expansion tank.
•Unscrew the cap carefully ⇒.
•Refill only new coolant according to the Volkswagen specification ⇒ Coolant specification⇒
.
Insufficient anti-freeze in the coolant system can cause the engine to break down and
cause serious injuries.
•Please note that the amount of correct coolant additive used must be sufficient for the
lowest ambient temperature that you expect the vehicle to be exposed to.
•Coolant can freeze at extremely cold outside temperatures, causing the vehicle to
break down. Vehicle occupants with inadequate winter clothing could then freeze to
death as the heating will also no longer function.
WARNING
Never mix genuine coolant additives with other coolants that have not been approved by
Volkswagen. Mixing other coolants could cause serious damage to the engine and cooling
system.
•If the liquid in the coolant expansion tank is not pink (colouring results from mixing the
purple coolant additive with distilled water) but for example, brown instead, - G 13 - has
been mixed with an unsuitable coolant. The coolant must be changed as soon as
possible if this is the case. Failure to observe this point can result in serious faults or
engine damage.
NOTICE

•Only top up coolant if there is coolant residue in the expansion tank. If this is not observed, the
engine could be damaged. If you cannot see any coolant in the expansion tank do not drive
on. Seek professional assistance.
•If you can see coolant residue in the coolant expansion tank, refill coolant until the level remains
stable.
•The coolant level must be between the marks on the coolant expansion tank ⇒ Fig. 229. Do
not fill above the top edge of the marked area⇒.
•Close the cap tightly.
•If in an emergency you do not have access to the required specification ⇒ Coolant 
specification, do not use any other coolant additive! Instead, initially refill with distilled water⇒
only. Then add the correct proportion of coolant additive as soon as possible ⇒ Coolant 
specification.
Brake fluid
Hot steam or coolant can cause serious burns.
•Never open the bonnet if you can see or hear steam or engine coolant coming out of
the engine compartment. Always wait until you can no longer see or hear escaping
steam or coolant.
•Always allow the engine to cool down completely before carefully opening the bonnet.
Hot components can burn the skin.
•The following points should be noted before opening the bonnet once the engine has
cooled down:
- Switch on the electronic parking brake and move the selector lever to position P
or move the gear lever to the neutral position.
- Switch off the ignition and remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.
•The cooling system is under pressure when the engine is hot. Never open the cap of
the coolant expansion tank when the engine is hot. Coolant may spray out and cause
serious burns and other injuries.
- Turn the cap slowly and very carefully anti-clockwise while exerting gentle
downward pressure on the cap.
- Always protect the face, hands and arms from hot coolant or steam with a large,
thick cloth.
•When refilling, do not spill any service fluids on engine components or on the exhaust
system. The spilt service fluids can start a fire. In certain circumstances, the ethylene
glycol in the engine can catch fire.
WARNING
•Refill only with distilled water. All other types of water can cause corrosion in the
engine due to the chemical components contained therein. This can also lead to engine
failure. If any other type of water than distilled water is refilled, the fluid in the cooling
system should be completely replaced immediately by a qualified workshop.
•Do not fill coolant above the top of the marked area ⇒ Fig. 229. Otherwise the excess
coolant will be pressed out of the cooling system when the engine is hot and could
cause damage.
•If a large amount of coolant has been lost, do not refill the coolant until the engine has
cooled completely. Heavy coolant loss is an indication of leaks in the engine cooling
system. The engine cooling system should be checked by a qualified workshop as
soon as possible. Failure to do so can result in engine damage.
•Do not top up with coolant if there is no more coolant in the coolant expansion tank. Air
could have entered the cooling system. Do not drive on! Seek expert assistance. Failure
to do so can result in engine damage.
•When topping up service fluids, please ensure that you pour the correct service fluids
into the correct openings. The use of incorrect service fluids could result in serious
malfunctions and engine damage.

Safety certificate
There is a safety certificate on the door pillar of the driver door which states that all necessary
safety standards and specifications from the transport safety authorities of the particular country
were met at the time of production. The month and year of production and the chassis number may
also be listed. Observe notes in the owner's manual.
