2017 VOLKSWAGEN TIGUAN heater

The auxiliary heater runs on for a short time after it is switched off manually or automatically so that
the remaining fuel in the system can be burnt off.
When the vehicle is at a standstill, the auxiliary heater can be activated up to three times in
succession for the maximum operating duration.
Operating noises can be heard if the auxiliary heater is switched on.
The 12-volt battery will discharge if the auxiliary heater or ventilation is run several times
over an extended period. Drive the vehicle for an appropriate distance in order to recharge the 12-
volt vehicle battery.
When parked on an incline, the fuel gauge indication (just above the reserve quantity) may
be inaccurate and lead to functional restrictions of the auxiliary heater.
The auxiliary heater may switch on automatically as a supplementary heating measure when
the engine is started at temperatures below +5°C (+41°F). The supplementary heating function is
switched off again automatically after a short time.

Fuel may run out of the fuel canister. This could cause fire and injuries.
•Do not carry fuel canisters in the vehicle.
CAUTION
Incorrect refuelling can lead to damage to the vehicle.
•Only use fuels that have been approved for the vehicle.
•Do not use fuels containing metals and only use approved additives.
•Spilt fuel should be removed from all vehicle components immediately.
NOTICE

Diesel
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Vehicles with a diesel engine must be run on diesel ⇒. If you use diesel with a high sulphur
content, the service intervals are shorter ⇒ Service. Information on countries that use diesel with a
high sulphur content is available from your Volkswagen dealership.
The fuel quality affects the running properties, performance and service life of the engine. You
should therefore use fuel that already contains suitable service additives if possible ⇒.
Information on the fuel standards can be found in the chapter on fuel standards ⇒ Fuel standards.
Winter-grade diesel fuel and filter preheater system
Winter-grade diesel fuel, which can be used at temperatures below -20°C (-4°F), is available during
the cold months. In countries with different climates, diesel for other temperature conditions is
usually available. Information is available from your Volkswagen dealership and filling stations in
the respective country.
Diesel vehicles are equipped with a filter pre-heater system. When using winter-grade diesel fuel,
the fuel system is safe for operation at temperatures down to around -24°C (-11°F).
However, if the fuel has waxed to such an extent that the engine will not start at temperatures
below -24°C (-11°F), place the vehicle in a heated garage or workshop for a while ⇒.
At cold temperatures, louder noises may occur in the diesel engine and the exhaust gas may
be tinged blue.

Checklist
The following steps should always be carried out in the specified order before working in
the engine compartment ⇒:
There are rotating components in the engine compartment that can cause serious injury.
•Never place your hand near these components or in the radiator fan. Touching the
rotary blades can result in serious injuries. The fan is temperature-controlled and can
start automatically, even if the ignition has been switched off and the vehicle key has
been removed from the ignition lock.
•If any work has to be performed when the engine is started or with the engine running,
there is an additional, potentially fatal, safety risk from the rotating parts, such as the
poly V-belts, alternator, radiator fan etc., and from the high-voltage ignition system.
Always be particularly careful.
- Always ensure that no body parts, jewellery, ties, loose items of clothing or long
hair can be caught up in rotating engine components. Before starting work,
remove any jewellery and ties, tie up long hair and pull clothes in tightly to avoid
them getting caught in the engine compartment.
- Always take due care and attention when depressing the accelerator. The vehicle
could move, even if the electronic parking brake is applied.
•Always ensure you have not left any objects, such as cleaning cloths and tools, in the
engine compartment. Any forgotten items can cause malfunctions, engine damage and
fires.
