warning light VOLKSWAGEN TOUAREG 2012 Repair Manual

The air recirculation mode helps prevent outside air from entering the vehicle interior.
In very hot or cold outside temperatures, temporarily switch to manual air recirculation in order to cool or heat the vehicle interior faster.
For safety reasons, air recirculation is switched off if you push the  button ⇒ .
Switching air recirculation on and off manually
Switching on: Press the 3 button repeatedly until the indicator light in the button comes on.
Switching off: Press the 3 button repeatedly until the indicator light in the button goes out.
Switching air recirculation on and off automatically
x Press the CLIMATE Infotainment button.
x Tap the Extras function key.
x Switch automatic air recirculation on or off by tapping the Automatic air recirculation function key.
If the check box in the function key is checked =, automatic air recirculation is switched on.
What automatic air recirculation does
In automatic air recirculation mode, fresh air will enter the passenger compartment. If the system detects an increased concentration of pollutants in the outside air, it automatically switches to air recirculation. As soon as the pollutant level is back in the normal range, air recirculation is switched off.
Unpleasant odors cannot be detected by the system.
To keep the windows from fogging up, automatic air recirculation is not switched on automatically in certain circumstances.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents, colli-sions and serious personal injury.
x Never use air recirculation mode over an extended period of time, since no fresh air will enter the passenger compartment.
x When the air conditioner is off and recirculation mode is on, condensation can quickly form on the windows and greatly reduce visibility.
x Always switch off recirculation mode when it is not needed.
NOTICE
Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation system can leave residue on the evaporator and on the dust and pollen active carbon filter, resulting in permanent odors whenever the air conditioner is switched on.
When backing up and while the automatic wiper/washer is operating, air recirculation is briefly activated to avoid unpleasant odors in the passenger compartment. This feature only works if automat-
ic air recirculation is enabled ⇒  Switching air recirculation on and off automatically.

WARNING
Off-road driving can be dangerous, can lead to accidents, vehicle damage, stranding in re-mote areas, and serious personal injury.
x Never drive too fast or for terrain and weather conditions.
x Always adjust your speed and driving style to road, terrain, traffic, and weather condi-tions.
x Always avoid sudden, sharp maneuvers that increase the risk of loss of vehicle control or getting stuck.
x When driving off-road look and think ahead, expect the unexpected.
x To reduce the risk of loss of control and serious personal injury, never use the cruise control when driving off-road. Cruise control is designed for highway use. It is completely unsuitable for off-road situations and can even be dangerous when used off-road.
NOTICE
Always make sure the vehicle has enough ground clearance. Severe damage to the underbody can occur if the vehicle bottoms out. The damage could disable the vehicle and leave you stranded.

WARNING
The engine compartment of any motor vehicle is a potentially dangerous area and can cause serious personal injury.
x Always use extreme caution when doing any work in the engine compartment. Always follow commonly accepted safety practices and use common sense. Never risk personal injury.
x Never perform any work in the engine compartment unless you know exactly how to carry out the job and have the correct technical information and the correct tools.
x If you are uncertain about what to do, have the work performed by an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified work-shop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon) headlights and H7 bulbs replaced by a qualified technician. Serious personal injury may re-sult from improperly performed work.
x Never open or close the engine hood if steam or coolant is escaping. Hot steam or coolant can cause serious burns. Always wait until you no longer see or hear steam or coolant escap-ing from the engine.
x Always let the engine cool down completely before carefully opening the hood.
x Hot parts of the engine and the exhaust system will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Apply the electronic parking brake and shift the transmission into Park (P).
– 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.
– 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.

WARNING
High voltage systems in the engine compartment can cause electrical shocks or even elec-trocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially careful when using jumper cables. The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or being started:
– Never touch ignition cables. Never touch other components of the high-voltage elec-tronic ignition system.
– Never touch the wiring of the HID – High Intensity Discharge (Xenon) headlights.
x Read and heed the important information and warnings on cleaning the engine compart-
ment ⇒  Cleaning the engine compartment.
WARNING
Moving parts in the engine compartment can cause serious personal injury on contact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can cause serious personal injury. Always remember that the radiator fan is temperature-controlled and can come on suddenly even when the engine has been switched off for a while and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in rotat-ing engine parts. Before starting any work remove your jewelry, take off your necktie, tie back and cover your hair, and do not wear clothing that can hang down and get caught in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools. Objects left behind can cause malfunctions, engine damage, and even fires.
WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing burns and other serious personal injuries!
x Do not smoke.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.

NOTICE
When changing or topping off fluids, make sure that you pour the fluids into the correct reser-voirs. Adding the wrong type of operating fluids will cause serious malfunctions and engine damage!
Fluid leaks are harmful to the environment. Regularly check the ground underneath your vehicle for this reason. If you find spots of oil or other fluids, have your vehicle checked by your authorized Volkswagen dealer or authorized Volkswagen Service Facility. Dispose of leaked operating fluids properly.
