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

malfunction.

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.

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 system 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.

Engine Tire dimensions Tire pressure
bar psi kPa
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 274. 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. If different tires are installed that do not have the same cold tire
inflation pressure as the tires originally installed on your vehicle, the Tire Pressure Monitoring
System cannot properly monitor tire inflation pressures unless the TPMS is reset to the new tire
pressures 229. Authorized Volkswagen dealers and authorized Volkswagen Service Facilities have
the necessary special tools and can reset the TPMS for the new tires on your vehicle.

whenever you change or adjust the cold tire inflation pressure or 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

x Accessories and other things installed in front of the cooling air intakes impair the
efficiency of the engine coolant. The engine can overheat under high outside temperatures or
under high engine loads!
Leaking operating fluids can pollute the environment. Collect leaking operating fluids in suitable
containers and dispose of them properly in accordance with applicable environmental laws and
regulations.
CB radio equipment

Although your vehicle is not equipped with an EDR, it is equipped with a number of electronic control
modules for various vehicle systems, such as engine management, emission control, airbags, and
safety belts.
These electronic control modules also record data during normal vehicle operation for diagnostic and
repair purposes. Their recording capability is limited to data (no sound is recorded). Only a small
amount of data is actually recorded over a very limited period of time, or stored when a system fault is
detected by a control module. Some of the data stored may relate to vehicle speed, direction, or
braking, as well as restraint system use and performance in the event of a crash. Stored data can only
be read and downloaded with special equipment.

x If vehicle components bearing safety certificates, stickers, or labels are replaced, make certain that
the firm doing the work attaches new conforming certificates, stickers, or labels to the same part of the
new components.
Safety Compliance Certification Label
A safety certificate affixed to the door jamb in the driver door confirms that at time of production all
necessary safety standards and requirements of the traffic safety agency of the respective country
were met. The month and year of production as well as the vehicle identification number may be listed
as well.
Radiator fan and high voltage warning sticker
A warning sticker about the radiator fan and the high voltage of the electrical system is located in the
engine compartment next to the engine hood release. The vehicle ignition system complies with the
Canadian standard ICES-002.
