Normal range
Engine coolant level too
low.
Check the engine coolant level after the
engine has cooled down and add engine
coolant if low.
If the engine coolant level is correct or the
problem continues after adding coolant, do
not drive any farther. Contact an
authorized Volkswagen dealer or
authorized Volkswagen Service Facility.
These instructions apply only when the
coolant temperature stays in the normal
range. Stop immediately if the needle goes
into the red warning zone (C).
– Engine coolant system
malfunction.

The engine cooling system is filled at the factory with a mixture of specially conditioned water and at
least 40 percent of Volkswagen engine coolant additive G 13 (TL-VW 774 J). This engine coolant
additive is pink.
This mixture provides antifreeze protection down to -13 °F (-25 °C). It also helps to protect the light
alloy parts in the engine cooling system against corrosion. In addition, the mixture helps prevent
calcium deposits and increases the boiling point of the engine coolant.
To protect the engine, the mixture must always contain at least 40% coolant additive even in warm
weather or climates where antifreeze protection is not needed.
If more antifreeze protection is needed for climate conditions, the percentage of coolant additive can
be increased. However, the coolant additive percentage must never be more than 60%; otherwise,
antifreeze protection is reduced and the ability of the mixture to cool the engine is also reduced.
When adding engine coolant, use a mixture of distilled water and at least 40% coolant additive G 13
or G 12 plus-plus (TL-VW 774 G) for optimum corrosion protection ⇒ .
Do not mix G 13 with G 12 plus or G 11. Mixing these coolant additives together significantly reduces
corrosion protection ⇒ . and can lead to engine damage that is not covered by any Volkswagen
Limited Warranty
WARNING
Too little antifreeze protection in the engine cooling system can cause engine failure and
severe injuries.
x Always make sure there is enough of the correct coolant additive to provide proper
antifreeze protection at the coldest temperatures that can be expected where the vehicle will
be used.
x At extremely cold temperatures, the coolant could freeze, causing the vehicle to break
down. The heater would also not work, and vehicle occupants could be without protection at
subfreezing temperatures.
NOTICE
Never mix original Volkswagen engine coolant additives with other additives not approved by
Volkswagen. Mixing Volkswagen coolant additives with coolant additives made by other
manufacturers can seriously damage the engine and the engine cooling system.
x If the fluid in the engine coolant reservoir is any color but pink, then G 13 was mixed with a
different engine coolant. If this is the case, the engine coolant must be replaced immediately.
Otherwise serious malfunctions or engine damage can occur!
Engine coolant and engine coolant additives can pollute the environment. Collect leaking
operating fluids and dispose of them properly in accordance with applicable environmental laws and
regulations.

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
components 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 Keyless Access, 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 ⇒ page 227.
– 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
authorized 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 . Excess engine
coolant may be forced out of the engine cooling system when it gets hot and cause damage.
x In the case of significant engine coolant loss, refill engine coolant only when the engine is
completely cooled down. Significant engine coolant loss is a sign of leaks in the cooling
system. Have the engine cooling system checked immediately by an authorized Volkswagen
dealer or an authorized Volkswagen Service Facility. Otherwise the engine may be damaged!
x When changing or topping off operating fluids, make sure that you pour the fluids into the
correct reservoirs. Serious malfunctions and engine damage can result if you pour operating
fluids into the wrong reservoir.

requirements regarding handling and disposal of the vehicle or parts of its restraint system, including
airbag modules and safety belts with pretensioners. Authorized Volkswagen dealers and authorized
Volkswagen Service Facilities are familiar with the requirements, and we recommend that you have
them perform this service for you.
Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle
battery has been replaced may change or delete settings (including time, date, personal convenience
settings and programming). Check the settings and correct as necessary once the vehicle battery has
built up a sufficient charge.

The Tire Pressure Monitoring System is configured at the factory with the correct tire inflation
pressure applicable for the vehicle model, engine and factory-installed tires. The tire inflation
pressure is listed on the tire inflation pressure label on the driver door jamb. The tire inflation
pressures for the road tires are listed on this label. The inflation pressure for the compact spare is as
specified on the tire pressure label or on a separate label for the compact spare, if there is one. In
the event of a discrepancy between the above figures and the tire pressures listed on the tire
inflation pressure label, the pressures listed on the label are the ones you should use. The listed
pressure applies to all road tires. The Tire Pressure Monitoring System must be recalibrated using
the SET button whenever you remove and remount or change any wheel or tire on the vehicle, even
if the reinstalled or replacement wheels and tires are identical to those that were removed and even
if the tire pressure does not change.
