WARNING
Driving on today's roads demands the full attention of the driver at all times. Driver distrac-tion causes accidents, collisions and serious personal injury!
x Never access menus when the vehicle is moving.
Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle battery has been replaced may change or delete settings (including time, date, personal convenience settings and programming). Check the settings and correct as necessary once the vehicle battery has built up a sufficient charge.

Remote start feature
Press the button (3) to activate the remote start feature ⇒  Starting and stopping the engine.
Replacement vehicle keys
The vehicle identification number is required to get a replacement key or an additional remote control vehicle key.
Up to 8 vehicle keys, each of which must be properly cut, coded, programmed, and synchronized, can be used with your vehicle.
Each new vehicle key contains a microchip and must be coded with the data from the vehicle's elec-tronic immobilizer. A vehicle key will not work if it does not contain a microchip or contains a chip that is not coded, even if the key bit was cut correctly.
You can obtain additional or duplicate remote control vehicle keys from authorized Volkswagen deal-ers, authorized Volkswagen Service Facilities, and from certain independent repair facilities and lock-smiths which are qualified to make remote control vehicle keys.
Each vehicle key must be programmed by an authorized Volkswagen dealer, an authorized Volkswagen Service Facility in order for it to work with your vehicle.
To find the nearest qualified independent repair facility, locksmith, or Volkswagen dealer which can cut and code replacement vehicle keys, call the VW Customer Care Hotline at 1-800-822-8987 or visit http://www.vw.com and search for “replacement keys.”
Canadian customers can contact an authorized Volkswagen dealer or Volkswagen Service Facility or call the Volkswagen Canada Customer CARE Center at (1-800-822-8987).
NOTICE
The remote control vehicle keys contain electrical components. Protect them from damage, moisture and rough handling.
Do not press the buttons on the remote control vehicle key unless you actually want to use the function in question. Since terrain and conditions vary, pressing a button on the remote control vehicle key when it is not necessary may unlock the vehicle or set off the panic alarm, even if you think you are out of range.
Remote control vehicle key functions can be temporarily disrupted by interference from transmit-ters near the vehicle that use the same frequency range (such as radio equipment or mobile phones).
Things between the remote control vehicle key and vehicle, bad weather, as well as a weak battery can reduce the operating range.
If the remote control vehicle key buttons ⇒  Vehicle key set or the power locking buttons ⇒  Un-locking and locking the vehicle from the inside are pushed repeatedly in quick succession, the power locking system is switched off for a brief period to help keep it from being overloaded. The vehicle is then unlocked for about 30 seconds. Unless a door or the luggage compartment lid is opened in this span of time, the vehicle is automatically locked afterwards.

Malfunction Possible cause Possible remedy
Garage door or electrical drive does not work.
Distance or transmission angle too great. Try different distances and angles to the receiver.
Garage door or electrical drive not compatible. May not comply with legal requirements and may have to be replaced.
Incorrect programming. Reprogram the garage door opener.

DANGER
20 mm button cells and other lithium batteries will cause serious personal injury and even death within a short time if swallowed.
x Always keep hand-held remote control devices with batteries, spare batteries, as well as dead button cell and larger 20 mm batteries out of the reach of children.
x Get medical attention immediately if you suspect that a battery has been swallowed.
WARNING
Improper use of the HomeLink® Universal Transmitter can cause serious or even fatal per-sonal injury.
x Garage doors operate with enough force to cause serious personal injury.
x Never let anyone get in the way of a garage door when it is opening or closing.
x When programming the HomeLink® Universal Transmitter, you may be operating a garage door or estate gate. Always make sure that people and objects are out of the way to help prevent serious personal injury or property damage.
x When operating the “training” button on a garage door opener with a rolling code, you will need to stand on a ladder or step-stool. Always take extra precautions to prevent falls and serious injury.
x Never use the HomeLink® Universal Transmitter with any garage door opener that does not have the safety stop-and-reverse feature, as required by federal safety standards. This includes any garage door opener model manufactured before April 1, 1982.
x A garage door opener that cannot detect an object, signaling the door to stop and reverse, does not meet current federal safety standards. Using a garage door opener without these features increases the risk of serious injury or death.
x Follow the installation manual and the included safety information from the manufacturer when using the remote-controlled garage door opener or electrical drive.
NOTICE
The wrong batteries can damage the hand-held remote control. Replace a dead battery with one that has the same voltage, size, and specifications.
Please dispose of old batteries properly and in an environmentally responsible manner. Always keep them out of the reach of children.

WARNING
Working on the batteries or the electrical system in your vehicle can cause serious acid burns, fires, explosions, or electrical shocks. Always read and heed the following WARNINGS and safety precautions before working on the batteries or the electrical system.
x Before working on the electrical system, always switch off the ignition and all electrical consumers and disconnect the negative (-) cable from the standard 12 Volt battery.
x When you change a light bulb, always switch off the light first.
x Always keep children away from battery acid and vehicle batteries in general.
x Always wear eye protection. Never let battery acid or lead particles come into contact with your eyes, skin, or clothing.
x Sulfuric battery acid is very corrosive. It can burn unprotected skin and cause blindness. Always wear protective gloves and eye protection. To reduce your risk of injury, never tilt the batteries, as this could spill acid through the vents and burn you.
x If you get battery acid in your eyes or on your skin, immediately rinse with cold water for several minutes and then get immediate medical attention. If you swallow any battery acid, get medical attention immediately.
x When disconnecting the batteries from the vehicle electrical system, always disconnect the negative cable (-) first and then the positive cable (+).
x Always switch off all electrical consumers before reconnecting 12 Volt batteries. Recon-nect the plus cable (+) first and then the negative cable (-). Never reverse the polarity of the connections. This could cause a fire.
x A highly explosive mixture of gases is given off when the battery is being charged.
x Do not smoke and avoid fires, sparks, and open flames when working. Never create sparks or electrostatic charges when handling cables and electrical equipment. Never short circuit the battery terminals. High-energy sparks can cause serious personal injury.
x Never use or attempt to charge a damaged or frozen battery, or a battery that was frozen but has thawed. Charging a frozen or thawed battery could cause explosions and chemical burns! Replace damaged or frozen vehicle batteries immediately. A dead battery can freeze at temperatures around +32 °F (0 °C).
x If the battery has a vent line or tube, make sure that it is properly connected to the battery.
x Always make sure that the vent line is securely attached to a vehicle battery that is located in the luggage compartment.
WARNING
California Proposition 65 Warning
x Battery posts, terminals, and related accessories contain lead and lead components, chemicals known to the State of California to cause cancer and reproductive harm. Wash your hands after handling.
NOTICE
x Do not expose the vehicle battery to direct sunlight for an extended period of time as ultra-violet rays may damage the battery housing.

x If the vehicle is left standing in the cold for a long time, protect the vehicle battery from freezing. A battery will be permanently damaged by freezing.
