Vehicles with Keyless Access
If the ignition will not start after reconnecting the vehicle battery, lock the vehicle from the outside and
unlock it again ⇒ Unlocking or locking the vehicle with Keyless Access. Then try to start the ignition again. If the ignition cannot be switched on, contact an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop for assistance.
Automatic electrical load deactivation
If the vehicle battery drain is high, the intelligent onboard electrical system management automatically takes steps to help prevent battery drain.
x The idle speed is increased so that the alternator provides more power.
x The power to devices that consume a lot of electricity is cut back or switched off completely.
x When the engine is started, the power supply to the 12 Volt sockets is temporarily interrupted.
The onboard electrical system management cannot always keep the battery from being drained. For example, the battery will drain if the engine is not running, but the ignition is switched on or the parking lights are left on for a long time when parked.
Battery disconnection in an accident with airbag deployment
In vehicles with a battery in the luggage compartment, the electrical connection to the battery is disconnected automatically in a collision with airbag deployment. This helps to prevent a short-circuit.
What drains the battery?
x Long periods when the engine is not running, especially when the ignition is on.
x Using electrical systems or devices when the engine is switched off.
x Leaving the vehicle unlocked for several days when not in use.
x The selector lever is left for a long period of time in any position other than (P) when the ignition is
switched off ⇒ Automatic transmission: Selector lever.
WARNING
Failure to use the proper battery with proper mounting and connections may cause short circuits, fires, and serious personal injuries.
x Always use only maintenance-free or cycle-free, leakproof batteries with the same specifications and dimensions as the original equipment battery. Specifications are listed on the battery housing.
WARNING
When the vehicle battery is charged, it produces highly explosive hydrogen gas.
x Charge vehicle batteries only in well-ventilated areas.
x Never charge a frozen or thawed battery. A dead battery can freeze at temperatures around +32 °F (0 °C).
x You must replace the vehicle battery if it was frozen.
x Incorrectly connected cables can cause a short-circuit. First connect the positive cable (+) and then the negative cable (-).
WARNING
After the vehicle has been washed, the wet brakes or, in winter, brake discs or pads coated with ice, react slower and need longer stopping distances.
x Always dry the brakes and clean off any ice coatings with a few careful applications of the brake. Make sure not to endanger other motorists or cyclists or disobey legal requirements.
CAUTION
Sharp edges under the vehicle can cut exposed skin.
x Always protect your hands and arms from cuts on sharp metal edges when cleaning the underbody, the inside of the wheel housings, etc.
NOTICE
x The water temperature must not be more than +140 °F (+60 °C).
x To help prevent damage to the paint, do not wash the vehicle in direct sunlight.
x Do not use insect sponges, abrasive kitchen sponges or similar things to clean the vehicle. These can damage the paint finish.
x Never clean headlights with a dry cloth or sponge. Always use a wet cloth or sponge. For best results use soapy water.
x When washing or rinsing the vehicle in cold weather, do not let water get into the lock cylinders or point the hose at gaps around the doors, hood, or rear hatch. The water could freeze on the locks and seals and make it difficult to open the vehicle!
NOTICE
To help prevent vehicle damage in a car wash:
x Compare the vehicle track width with the dimensions of the guide rails in the car wash to help prevent damage to wheel rims and tires!
x Switch off the rain sensor before driving through a car wash 122.
x Make sure there is enough clearance for the height and width of the vehicle.
x To help prevent paint damage to the engine hood, place wiper blades against the windshield after they have dried. Do not let them snap back into place.
x Fold the outside mirrors toward the vehicle body. Do not fold power mirrors manually!
x Lock the rear hatch to prevent unintentional opening in the car wash.
