remove battery VOLKSWAGEN PASSAT 2008 Owners Manual

Volkswagen recommends having the battery in the remote control vehicle key changed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
The battery is on the back of the remote control vehicle key under a cover ⇒ fig. 30.
When changing the battery, pay attention to the correct polarity and use the same type of battery
⇒ .
Replacing the battery
x Unfold the key bit on the remote control vehicle key, Remote control vehicle keys, Remote control vehicle keys, Remote control vehicle keys.
x Remove the cover on the back of the remote control vehicle key in the direction of the arrow ⇒ .
x Use a thin object to pry the battery out of the battery compartment ⇒ fig. 31.
x Position the new battery in as shown and press it into the battery compartment (opposite to
direction of the arrow) ⇒ .
x Position the cover as shown ⇒ fig. 30 and press it down (opposite to direction of the arrow) until you hear it click into place.
NOTICE
x Changing the battery improperly can damage the remote control vehicle key.
x Using the wrong battery can damage the remote control vehicle key. Replace a dead battery with a new one that has the same voltage, size, and specifications.
x Make sure the plus and minus poles of the battery are correctly positioned.
Dispose of old batteries in an environmentally responsible manner and keep them out of the reach of children.
Batteries of the type used in your remote control vehicle key may contain Perchlorate Material. Special handling may apply – see http://www.dtsc.ca.gov/hazardouswaste/perchlorate. Obey all legal requirements regarding handling and disposal of these batteries. Authorized Volkswagen dealers and authorized Volkswagen Service Facilities are familiar with the requirements, and we recommend that you have them perform this service for you.
Synchronizing the remote control vehicle key

WARNING
Improper use of electrical seat controls can cause serious personal injuries.
x The front seats in your vehicle can be electrically adjusted even when the vehicle key has been removed from the ignition or, on a vehicle with Keyless Access, even if there is no key in the vehicle.
x Never leave children and persons who need help in the vehicle alone because the unsupervised use of the electric seat adjustments can result in serious personal injury.
x Always make sure that no one is in the way while the front seats are being adjusted, or while calling up the stored memory settings for the front seats. In an emergency, stop automatic seat adjustment by pressing a seat adjustment switch.
NOTICE
To help prevent damage to electrical parts in the seat, do not kneel on the front seats or apply concentrated pressure to a small area of the seat or backrest.
If the vehicle battery is too weak, the electrical seat adjustment controls may not work.
Starting the engine stops seat adjustment.
When entering and exiting the vehicle, be careful not to come into contact with any switches that could change the seat adjustment.

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 build-up 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 transmission selector lever to put the lever into Park (P).

WARNING
High voltage systems in the engine compartment can cause electrical shocks or even electrocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially careful when using jumper cables. The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the engine is running or being started:
– Never touch ignition cables. Never touch other components of the high voltage electronic ignition system.
– Never touch the wiring of the HID – High Intensity Discharge (Xenon) headlights.
x Read and heed the important information and warnings on cleaning the engine compartment
WARNING
Moving parts in the engine compartment can cause serious personal injury on contact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can cause serious personal injury. Always remember that the radiator fan is temperature-controlled and can come on suddenly even when the engine has been switched off for a while and the key has been removed from the ignition.
x If you have to perform a check or repair when the engine is running, there are more risks from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in rotating engine parts. Before starting any work remove your jewelry, take off your necktie, tie back and cover your hair, and do not wear clothing that can hang down and get caught in moving engine parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the engine compartment, for example cleaning rags and tools. Objects left behind can cause malfunctions, engine damage, and even fires.
WARNING
Operating fluids and some materials in the engine compartment can catch fire easily, causing burns and other serious personal injuries!
x Do not smoke.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the engine. These fluids can ignite on hot engine parts and cause injuries.
x If work on the fuel system or the electrical system is necessary:
– Always disconnect the 12 Volt vehicle battery. Make sure the vehicle is unlocked when you disconnect the battery, or the alarm will go off. Never touch the electrical wiring of the ignition system.
– Never work near heaters, water heaters, or other open flames.
x Always have a functional, approved fire extinguisher nearby.

Starting the engine
x Start the engine of the vehicle with the good battery that is providing help and let it run at idle speed.
x Turn on the ignition of the vehicle with the dead battery. If the engine starts, wait 2 to 3 minutes
until it “runs smoothly” before removing the jumper cables as described below ⇒ . If the engine does not start within about 10 seconds, turn off the ignition and wait at least 1 minute; then try again.
Before removing the jumper cables
(1) Switch off the headlights (if they are on).
(2) In the vehicle with the dead battery, switch on the heater fan and the rear window defroster. This helps to minimize voltage spikes when the cables are disconnected.
Removing the jumper cables
With the engine running, remove the jumper cables in reverse order to the way they were connected.
(1) Disconnect the black (-) cable from the vehicle with the dead battery.
(2) Disconnect the black (-) cable from the other vehicle (vehicle with the good battery).
(3) Disconnect the red (+) cable from the other vehicle (vehicle with the good battery).
(4) Disconnect the red (+) cable from the vehicle with the dead battery.
(5) Close the battery cover or snap shut the cap on the positive jump-start terminal9, as the case may be.
