x In the case of significant engine coolant loss, refill engine coolant only when the engine is completely cooled down. Significant engine coolant loss is a sign of leaks in the cooling system. Have the engine cooling system checked immediately by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Otherwise the engine may be damaged!
x When changing or topping off operating fluids, make sure that you pour the fluids into the correct reservoirs. Serious malfunctions and engine damage can result if you pour operating fluids into the wrong reservoir.

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.
What drains the vehicle 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 Operating the CSC roof when the engine is switched off.
x The selector lever is left for a long period of time in any position other than P when the ignition is
switched off ⇒  Starting and stopping the engine.
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, leak-proof 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 (-).
NOTICE
x Never disconnect the vehicle battery or connect 2 vehicle batteries to each other when the ignition is switched on or the engine is running. Doing this may damage the electrical system or electronic components.

Cleaning the CSC roof
x Clean the CSC roof only when it is closed ⇒ page 66, CSC roof.
x Wash the CSC roof only in an automatic car wash or by hand.
x Never wash the CSC roof with a power washer.
x If the CSC roof is very dirty, contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
x The CSC roof gaskets (rubber seals) require special care ⇒ Caring for rubber door and window seals.
x Ask an authorized Volkswagen dealer or an authorized Volkswagen Service Facility if you have any additional questions about cleaning and caring for the CSC roof.
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.
WARNING
x Always close the CSC roof completely before washing. Never pause the CSC roof in a partly open position to clean the side roof pillar shafts or the roof rods. The CSC roof will go down by itself after a short time and could injure someone who is in its way.
x Never reach into the roof pillar compartments or the roof linkage, regardless of whether the roof is opened, closed, or somewhere in between.
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
Never wash the CSC roof with a power washer or use “brushless” automatic car washes. Water that is sprayed under high pressure may cause leaks or may damage the rubber seals of the CSC roof.
x Do not use any rubber care materials that contain silicone or any cleaners that contain acids such as industrial dust remover or insect remover on the CSC roof seals.
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 The heating elements for the rear defroster are on the inside of the rear window. Do not put stickers over the heating elements on the inside of the rear window and never clean the inside of the windows with corrosive or acidic cleaning agents or other chemicals that could damage the heating elements.
