2021 VOLKSWAGEN UP! engine coolant

Changing engine oil
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The engine oil must be changed regularly in accordance with the data given in the service
schedule.
The engine oil and filter should always be changed, and used oil disposed of, by a qualified
workshop due to the special tools and knowledge required. Volkswagen recommends using a
Volkswagen dealership for this purpose.
More details on the service intervals can be found in the service schedule.
Additives in the engine oil can cause new engine oil to discolour quickly. This is normal and does
not mean that the engine oil should be changed more frequently.
Before changing the engine oil, first find out where old oil can be disposed of properly near
you.
Used oil must be disposed of in accordance with regulations governing the protection of the
environment. Never dispose of old oil in locations such as gardens, woods, sewerage systems, on
streets and roads, or in rivers and waterways.

If, in exceptional cases, you have to carry out an oil change yourself, please note the
following:
•Always wear eye protection.
•Always allow the engine to cool down completely to avoid burns.
•Keep your arms horizontal when removing the oil drain plug with your fingers to help
prevent oil from running down your arm.
•Use a suitable container when draining the used oil. It must be at least large enough to
hold the entire quantity of engine oil required for refilling.
•Never store engine oil in empty food containers, bottles or any other non-original
containers as people finding these containers may not know that they contain engine oil.
•Engine oil is toxic and must be stored out of the reach of children.
WARNING
Engine coolant is toxic.
•Engine coolant should only be kept in sealed original containers in a safe place.
•Never store engine coolant in empty food containers, bottles or any other non-original
containers as people finding these containers may then drink the engine coolant.
•The engine coolant must be stored out of the reach of children.
•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

Coolant and coolant additives can pollute the environment. Spilt operating fluids must be
collected and disposed of properly and with respect for the environment.
Warning lamp for coolant
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Several warning and indicator lamps will light up briefly as a functional check when the ignition is
switched on. They will switch off after a few seconds.
Lit upPossible causeSolution
Engine coolant temperature is
too low in vehicles with natural
gas engine.
Avoid high engine speeds and heavy engine loads.
FlashesPossible causeSolution
Coolant temperature too high.
Do not drive on!
Stop the vehicle as soon as possible, and when
safe to do so. Switch off the engine, leave the
engine to cool down.
Coolant level too low.
Do not drive on!
After the engine has cooled down, check the
coolant level and refill engine coolant if the level is
too low ⇒ Checking the coolant level and refilling
coolant.
With display --.- in the
instrument cluster:
fault in the engine cooling
system.
Do not drive on!
Seek expert assistance.
In some vehicles, the coolant temperature display may be displayed on the screen of the
portable navigation device (delivered by Volkswagen) ⇒ Accessories, modifications, repairs and
renewal of parts.
Coolant specification
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The cooling system is filled at the factory with a mixture of specially prepared water and at least
40% coolant additive G 13 (TL-VW 774 J). The coolant additive is dyed purple. This mixture of
water and coolant additive gives the necessary frost protection down to -25°C (-13°F) and protects
the alloy parts of the cooling system against corrosion. The mixture also prevents scaling and
raises the boiling point of the coolant.
In order to protect the coolant system, the proportion of coolant additive must always be at least
40%, even if anti-freeze is not required in warm weather and warm climates.
If greater frost protection is required in very cold climates, the proportion of anti-freeze additive can
be increased. However, the percentage of coolant additive should not exceed 60%, as this would
reduce the frost protection and the cooling effect.
When topping up the coolant, a mixture of distilled water and at least 40% coolant additive - G 13 -
or - G 12 plus-plus - (TL-VW 774 G) (both of which are dyed purple) must be used in order to obtain
the optimum corrosion protection ⇒. Mixing - G 13 - with the coolant additives - G 12 plus - (TL-
VW 774 F), - G 12 - (dyed red) or - G 11 - (dyed blue-green) will significantly decrease the level of
corrosion protection and should therefore be avoided ⇒.
Failure to observe the warning lamps could lead to your vehicle breaking down in traffic, and
to accidents and serious injuries.
•Always observe any warning lamps that are lit up.
•Never ignore any warning lamps that are lit up.
•Stop the vehicle as soon as possible and when safe to do so.
WARNING
Failure to observe the illuminated indicator lamps could lead to the vehicle being damaged.
NOTICE

Coolant and coolant additives can pollute the environment. Spilt operating fluids must be
collected and disposed of properly and with respect for the environment.
Checking the coolant level and refilling coolant
Fig. 123 In the engine compartment: marking on the coolant expansion tank
Fig. 124 In the engine compartment: coolant expansion tank cap
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 ⇒ .
•The coolant expansion tank has the symbol on its cap ⇒ Fig. 124.
Checking the coolant level
•Check the coolant level at the side marking of the expansion tank when the engine is cold
⇒ Fig. 123.
•Refill the coolant if the liquid level is below the minimum marking (min). When the engine is
warm, the coolant level may be slightly above the top end of the marked area.
Refilling coolant
•Always protect your hands and arms from hot coolant or steam by placing a suitable cloth on
the cap of the coolant expansion tank.
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 brown instead of purple, for example, - G 13 -
has been mixed with another unsuitable engine 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

•Unscrew the cap carefully ⇒.
•Refill only new coolant according to the Volkswagen specification (⇒ Coolant specification) ⇒
.
•The coolant level must be between the marks on the expansion tank ⇒ Fig. 123. Do not fill up
over the top line of the marked area⇒!
•Close the cap tightly.
•If in an emergency you do not have access to the coolant of 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.
Vehicle battery
 Introduction
This chapter contains information on the followingsubjects:
⇒ Warning lamp
⇒ Checking the electrolyte level of the vehicle battery
⇒ Charging, replacing, disconnecting and connecting the vehicle battery
The vehicle battery is a component of the electrical system in the vehicle.
Never carry out any work on the electrical system if you are not familiar with the necessary
procedures and the general safety requirements and only unsuitable tools are available ⇒. The
work should be carried out by a qualified workshop if you are uncertain. Volkswagen recommends
using a Volkswagen dealership for this purpose. Serious injuries can be caused if work is carried
out incorrectly.
Location of the vehicle battery
The vehicle battery is located in the engine compartment.
Hot steam or engine 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 no escaping steam or coolant can be seen or
heard.
•Always allow the engine to cool down completely before carefully opening the bonnet. Hot
components can burn the skin.
•Before opening the bonnet once it has cooled down:
- Apply the handbrake fully and move the selector lever to position N or move the
manual gear lever to the neutral position.
- Remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.
•The engine 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 injuries.
- Turn the cap slowly and very carefully anticlockwise while exerting some 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 is refilled, the fluid in the engine cooling system should be
completely replaced immediately by a qualified workshop.
•Do not fill coolant above the top of the marked area ⇒ Fig. 123. 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.
•When refilling operating fluids, please ensure that the correct container is filled. The use of
incorrect operating fluids could result in serious malfunctions and engine damage!
