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!
