x Light switch in position  if the vehicle has no orientation lighting ⇒  Coming Home/Leaving Home features (orientation lighting).
WARNING
Daytime running 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 headlights (!54/) are 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 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.
Lights and vision features

Ambient (background) lighting
When the ignition and the headlights are switched on, ambient lights in the roof console light up.
There may also be lighting in the doors and footwells.
The interior and reading lights go out when you lock the vehicle or a few minutes after you re-move the vehicle key from the ignition. This helps to prevent unnecessary drain on the vehicle battery.

If the engine is switched off and accessories in the trailer are on and use electricity from the vehicle, the vehicle battery will be drained as long as the electrical systems of the vehicle and the trailer are connected.
Loading the trailer

Outer diameter
The diameter of a new, properly inflated tire.
Overall width
Total width measured at the exterior sidewalls of an inflated tire, including the additional width of labeling, decorations, or protective bands or ribs.
Passenger car tire

These include, for example, heavy-duty brakes, ride levelers, roof rack, heavy-duty battery, and special trim.
Radial ply tires
A pneumatic tire in which the ply cords that extend to the beads are laid at substantially 90 degrees to the centerline of the tread.
Recommended inflation pressure
The tire pressure recommended by the vehicle manufacturer for a tire of a specified size that has not been driven for more than a couple of miles (kilometers) at low speeds in the 3 hour period before the tire pressure is measured or adjusted.
Reinforced tire
A tire designed to operate at higher loads and at higher inflation pressures than the corresponding standard tire.
Rim
The outer edge of a wheel upon which the tire beads are seated.
Rim diameter
The nominal diameter of the wheel's tire bead seating surface. If you change your wheel size, to wheels of a different diameter, you will have to purchase new tires to match the new wheels.

WARNING
Improper use of vehicle keys can result in serious personal injury.
x Always take the key with you when you leave the vehicle. The engine can be started and vehicle systems such as the power windows can be operated, leading to serious personal injury.
x Never leave children, disabled persons, or anyone who cannot help themselves in the vehicle. The doors can be locked with the remote control vehicle key. This could result in people being trapped in the vehicle in an emergency. For example, depending on the time of year, people trapped in the vehicle can be exposed to very high or very low temperatures.
x Heat buildup in the passenger and luggage compartment of a parked vehicle can result in temperatures in the vehicle that are much higher than the outside temperatures, particularly in summer. Temperatures can quickly reach levels that can cause unconsciousness and death, particularly to small children.
x Never remove the key from the ignition switch while the vehicle is moving or rolling to a stop. The steering wheel will lock and you will not be able to steer or control the vehicle.
Leaving the key in the ignition for a long time when the engine is not running will drain the vehicle battery.
Leaving the selector lever for a long period of time in any position other than Park (P) when the ignition is switched off can drain the vehicle battery.
On automatic transmission vehicles, the vehicle key can be removed from the ignition switch only when the transmission is in Park (P). You may have to press the release button on the transmis-sion selector lever to put the lever into Park (P).

Power steering assist is reduced.
Stop, restart the engine, and drive a short distance. If the yellow warning light does not come on again, you do not need to have the steering system checked. Otherwise, have the steering checked imme-diately by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Vehicle battery was disconnected and has been reconnected. Drive a short distance at about 10–12 mph (15–20 km/h).


Flashes Possible cause Proper response
D= Electronic steering column lock malfunc-tion.

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 con-venience settings, and programming). Check the settings and correct as necessary once the vehicle battery has built up a sufficient charge.
