Engine coolant specifications

Checking engine coolant level and topping off

Fig. 168 Coolant expansion tank in the engine compartment.

Fig. 169 Coolant expansion tank cap in the engine compartment.

Checking engine coolant level
When the engine is cold, check the engine coolant level relative to
the marking on the side of the expansion tank ⇒ fig. 168.
If the coolant level in the tank is below the minimum mark (“min”),
add coolant. When the engine is warm, the engine coolant level may
be slightly above the upper edge of the marked range.
Adding engine coolant
Always protect face, hands and arms from hot escaping coolant or
steam by covering the cap with a large, thick rag.
Carefully unscrew the cap ⇒ .
Add only new engine coolant according to Volkswagen specifica-
tions (⇒ Engine coolant specifications) ⇒ .
The engine coolant level must be inside the marks on the side of
the reservoir ⇒ fig. 168. Do not fill above the top edge of the filling
range! ⇒ 
Screw the lid tightly.
Even in an emergency, do not use any other kind of coolant addi-
tive if engine coolant meeting Volkswagen specifications (⇒ page 456,
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.

failure. If you have added non-distilled water, take the vehicle
immediately to an authorized Volkswagen dealer or an author-
ized Volkswagen Service Facility to have the coolant system
drained, flushed, and refilled completely with the proper coolant.
Refill engine coolant only up to the top edge of the marked fill
range ⇒ fig. 168. Excess engine coolant may be forced out of the
engine cooling system when it gets hot and cause damage.
In the case of significant engine coolant loss, refill engine
coolant only when the engine is completely cooled down. Signif-
icant engine coolant loss is a sign of leaks in the cooling sys-
tem. Have the engine cooling system checked immediately by an
authorized Volkswagen dealer or an authorized Volkswagen Ser-
vice Facility. Otherwise the engine may be damaged!
When changing or topping off operating fluids, make sure that
you pour the fluids into the correct reservoirs. Serious malfunc-
tions and engine damage can result if you pour operating fluids
into the wrong reservoir.

Checking the vehicle battery electrolyte level

gine, the vehicle battery is in the engine compartment.

gine, the vehicle battery is on the left side of the luggage compart-
ment.

Vehicles with 3.6 liter engines: Open the luggage compartment lid

Opening the battery cover
Depending on the engine type, there are different kinds of battery
covers:
Vehicles with 2.0 liter engines: Press on the clip in direction of the
arrow ⇒ fig. 170 (1) and remove the cover upward.
Vehicles with 3.6 liter engines: Remove the trim panel to access
the vehicle battery ⇒ fig. 171.
Checking the vehicle battery acid level
If the lighting conditions are poor, use a flashlight so that you can
clearly see the battery acid level indicator and tell what color it is.
Never use an open flame or an unprotected light source.
The round battery window (“acid level indicator”) on the top of the
battery changes color, depending on the battery's electrolyte level.

Color Action
Light yellow
or colorless
Battery electrolyte level is too low.
The vehicle battery may need to be
replaced. Have it checked by an
authorized Volkswagen dealer or an
authorized Volkswagen Service Fa-
cility.
Black Battery electrolyte level is satisfacto-
ry.
