2015 VOLKSWAGEN PASSAT light assist

x Unlock the vehicle before disconnecting the battery; otherwise the alarm system will go off.
x First disconnect the negative cable (-) and then the positive cable (+) ⇒ .
Connecting the vehicle battery
x Prior to reconnecting the battery, switch off all electrical systems and devices and the ignition.
x Connect the positive cable (+) first and then the negative cable (-) ⇒ .
After the battery is connected and the ignition is switched on, different indicator lights may come on. They should go out after you drive a short distance at 10–12 mph (15–20 km/h). If the indicator lights do not go out , contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility and have the vehicle checked.
If the battery was disconnected for a long time, the next scheduled service may not be correctly calcu-
lated and displayed ⇒  Instrument cluster The maximum permissible service and maintenance inter-
vals are shown in the ⇒ Booklet Warranty and Maintenance.
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 and locking vehicles 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 and the cigarette lighter ⇒  Cigarette lighter 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 dis-connected automatically in a collision with airbag deployment. This helps to prevent a short-circuit.
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 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, leak-proof batteries with the same speci-fications and dimensions as the original equipment battery. Specifications are listed on the battery housing.

Checklist
For your own safety and that of your passengers, carry out the following steps in the order listed ⇒ :
1. Park the vehicle at a safe distance from traffic and on a suitable surface ⇒ .
2. Switch on emergency flashers by pressing the  switch ⇒ fig. 193.
3. Apply the parking brake to help prevent the vehicle from moving ⇒  Braking and parking.
4. Shift the transmission into Park (P) (automatic) or Neutral (manual only) ⇒  Shifting.
5. Stop the engine and remove the key from the ignition switch ⇒  Starting and stopping the engine.
6. Have all passengers exit and go to a safe location away from moving traffic, such as behind a guard rail.
7. Take all vehicle keys with you when leaving your vehicle.
8. Set up a warning triangle or other warning device in order to alert other motorists and cyclists.
9. Let the engine cool down and get expert assistance if necessary.
If the emergency flashers are on, use the turn signal lever to indicate a direction or lane change, for example when the vehicle is being towed. This temporarily interrupts the emergency flashers.
Switch on the emergency flashers when:
x Traffic suddenly slows down or stops in front of you to warn those approaching from behind.
x In any emergency situation.
x If the vehicle breaks down.
x When being towed.
Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to alert other motorists and cyclists to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common sense.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot. They can cause fires and serious personal injury.
x Never park where parts of the hot exhaust system or catalytic converter could ignite flammable materials, such as dry grass, brush, leaves, spilled fuel, etc.
NOTICE
To help prevent damage to the vehicle if you should have to push it a short distance by hand, never push against spoilers, lights, body panels, windows, or similar parts. Concentrating force on these parts of the vehicle can cause expensive damage that may not always be obvi-ous right away.

WARNING
Improper replacement of burned out headlights and other light bulbs can cause serious per-sonal injury.
x Stop! Always read and heed the WARNINGS before doing any work in the engine com-partment. The engine compartment of any motor vehicle is a potentially dangerous area, and work in this area can lead to serious personal injury.
x HID – High Intensity Discharge (Xenon) headlights get power from a high voltage source that can cause severe personal injury and even death if handled improperly.
x H7 bulbs and HID – High Intensity Discharge (Xenon) headlights are under high pressure and can explode if handled improperly.
x Always let a burned out light bulb cool down before replacing it.
x Never replace a light bulb unless you are familiar with all of the necessary procedures. In particular, never remove a headlight unless you know exactly how to carry out the job and have the correct tools and light bulbs.
x If you are uncertain about what to do, have the work performed by an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified work-shop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon) headlights and H7 bulbs replaced by a qualified technician.
x Do not touch the glass of light bulbs with your bare hands. Fingerprints left on the bulb evaporate due to the heat when the bulb is switched on and cause the reflector to “cloud.”
x There are sharp edges on and around the headlight housing in the engine compartment and the rear light housing. Wear hand protection if you replace bulbs.
NOTICE
After replacing a headlight bulb or other light bulb, always make sure that the rubber covers or plastic caps have been properly and securely reinstalled to help prevent water from getting into the electrical connections and headlight housing and damaging the electrical system.
LEDs cannot be replaced. Contact your authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.

WARNING
Improper use of jumper cables when jump-starting a vehicle with a dead battery can cause the battery to explode, leading to serious personal injury. To help reduce the risk of battery explosion:
x All work on the batteries or the electrical system in your vehicle can cause serious acid burns, fires, or electrical shocks. Always read and heed the following WARNINGS and safety
precautions before working on the batteries or the electrical system ⇒  Vehicle battery.
x Always wear proper eye protection. Never lean over the vehicle battery.
x Attach the jumper cables in the correct order: first the positive cable, then the negative cable.
x Never connect the negative cable from the vehicle providing starting assistance to parts of the fuel system or to the brake hoses or brake lines.
x Never allow the non-insulated parts of the battery clamps to touch.
x Never allow the jumper cable attached to the positive battery terminal to contact metal parts of the vehicle.
x Check the battery acid level indicator window on the vehicle battery. Use a flashlight, never a match, cigarette lighter, or other open flame. If you cannot see the color of the win-dow clearly, or if it is light yellow or colorless, do not jump-start the vehicle. Get expert assis-tance.
x Avoid electrostatic discharge in the vicinity of the vehicle battery. Sparks may cause the hydrogen gas escaping from the vehicle battery to ignite.
x Never jump-start a vehicle with a battery that is damaged or frozen or that was frozen and has thawed. The battery can explode. Replace the battery instead.
x Always follow the instructions of the jumper cable manufacturer.
x Always make sure that the battery providing starting assistance has the same voltage as the dead battery (12 V) and about the same capacity (see battery label).
x Batteries give off explosive hydrogen gas. Always keep fire, sparks, open flame and smok-ing materials away from batteries.
x Never connect the negative cable from the other vehicle directly to the negative terminal of the dead battery. The hydrogen gas from the battery is explosive.
x Never short out the battery terminals by connecting the positive (+) and negative (-) termi-nals with each other.
