WARNING
Daytime running lights and parking lights are not bright enough to let you see ahead or be seen by others when it is dark.
x Always switch on the low-beam headlights at dusk or when it is dark and whenever the weather is bad or visibility is poor.
x Never use the daytime running lights to see where you are going. They are not bright enough and will not let you see far enough ahead for safety, especially at dusk or when it is dark. Always switch on the low-beam headlights at dusk or when it is dark.
x The taillights do not come on with the daytime running lights. Unless the taillights are on, a vehicle cannot be seen by others in bad weather, at dusk, or when it is dark.
x Even if automatic headlight control (AUTO) is switched on, the low-beam headlights may still not come on by themselves in fog or heavy rain. You have to switch on the low-beam headlights manually.
In cool or humid weather, the insides of the headlights, the taillights, and turn signals can temporarily fog up. This is normal and does not affect the service life of the vehicle's lighting system.
Lights and vision features

When you move the selector lever to Reverse (R), the static cornering lights on both sides of the vehicle may come on so that you can see the area around the vehicle better when backing up.
The static cornering lights work only when the headlights are on. If you are using automatic headlight
control (headlight switch in the AUT O position ⇒ fig. 98), they work only when the headlights have been automatically switched on. The static cornering lights do not come on when the headlight switch is in the O position or when the fog lights themselves have been switched on, Switching lights on and off.
Automatic headlight control (AUTO)
Automatic headlight control is a convenience feature only and cannot always recognize all lighting and driving situations.
If the light switch is in the AUT O position, both vehicle lighting and instrument and switch lighting are
automatically switched on and off in the following situations ⇒ :

Automatic activation:Automatic deactivation:
If the low-light sensor registers darkness, for example when driving through a tunnel. If sufficient brightness is registered.

WARNING
Crashes and other accidents can happen when you cannot see the road ahead and when you cannot be seen by other motorists.
x Never use daytime running lights (DRL) to see where you are going. DRL are not bright enough to light up the roadway and be seen by other motorists. You will not be able to see far enough ahead for safety, especially at dusk or when it is dark. Always switch on the low-beam headlights at dusk or when it is dark.
x The taillights do not come on when the daytime running lights are switched on. A vehicle without taillights on cannot be seen by others in bad weather, at dusk, or when it is dark.
x If automatic headlight control (AUTO) is switched on, the low-beam headlights still may not be switched on in fog or heavy rain. You have to switch on the low-beam headlights yourself.
In cool or humid weather, the insides of the headlights, rear lights, and turn signals can temporarily fog up. This is normal and does not affect the service life of the vehicle's lighting system.
“Coming home” and “Leaving home” feature (orientation lighting)

WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious personal injuries.
x Always make sure all windows are clear of ice, snow and condensation for good visibility to the front, sides, and rear.
x Maximum heating output and defrosting performance are not possible until the engine has reached operating temperature. Wait until you have good visibility before driving off.
x Always make sure you know how to properly use the heating and ventilation systems as well as the rear window defroster that you will need for good visibility.
x Never use air recirculation for long periods of time. 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.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents, collisions and serious personal injury.
x Never switch off the fan for a long period of time and never use air recirculation a long period of time because no fresh air will enter the passenger compartment.
NOTICE
x If you think the air conditioner is not working properly or may be damaged, switch it off to help prevent more damage. Have the air conditioner checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
x Air conditioner repair requires specialized knowledge and special tools. Volkswagen recommends that you see an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
x 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.
If the air conditioner is switched off, the fresh outside air will not be dehumidified. To help keep the windows from fogging over, Volkswagen recommends leaving the air conditioner (compressor) switched on. Press the A/C button. The indicator light in the button must come on.
When it is very hot and humid outside, water condensation can drip from the air conditioner evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.
Keep the air intake slots in front of the windshield free of ice, snow and leaves in order to maintain proper functioning of the heating and ventilation systems.
Maximum heating output and defrosting performance are not possible until the engine has reached operating temperature.
