2007 VOLKSWAGEN EOS engine

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 ⇒ page 42, 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.

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 luggage compartment lid. The water could freeze on the locks and seals and make it difficult to open the vehicle!
x In cold weather, dry the rubber gaskets (rubber seals) and the surfaces they touch with a cloth to make sure they do not freeze shut.
NOTICE
To help prevent vehicle damage in a car wash:
x Close the CSC roof completely.
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 the vehicle through a car wash, Rain sensor.
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 folding mirrors manually!
x Lock the luggage compartment lid to help prevent unintentional opening in the car wash.
Washing with a power washer

Check all wiper blades regularly. Wiper blades that grab and squeak must be replaced if worn or
damaged and cleaned if dirty ⇒ .
Replace worn or damaged wiper blades immediately. Replacement blades may be purchased from any authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Lifting and tilting windshield wiper arms
Move the wiper arms to the service position before lifting them away from the windshield ⇒ page 198, Windshield wipers and washer.
It is not possible to lift the wiper arms away from the windshield when they are not in the service position.
When lifting or replacing a wiper blade on a window, grip it only by its mounting and not by the blade itself.
Cleaning the wiper blades
x Lift the wiper arm(s) away from the windshield.
x Using a soft cloth, carefully remove dust and dirt from the wiper blades.
x If the blades are very dirty, carefully clean them with a sponge or cloth ⇒ .
x Carefully fold the wiper arm back down onto the windshield.
Changing wiper blades
x Lift the wiper arm(s) away from the windshield.
x Press and hold the release button ⇒ fig. 159 (1).
x While lifting the wiper blade in the direction of the wiper arm, pull off the wiper blade in the direction of the arrow. This may require moderate force.
x Install a new wiper blade of same length and type onto the wiper arm by pushing in the opposite direction of the arrow until it latches.
x Carefully fold the wiper arm back down onto the windshield.
WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of accidents and severe injuries.
x Always change wiper blades if they are damaged or worn, and if they cannot clean the windows sufficiently.
NOTICE
x Damaged or dirty wiper blades can scratch the windshield.
x Solvents, abrasive sponges and sharp-edged objects will damage the graphite coating on the wiper blades.
x Do not clean the windows with gasoline, nail polish remover, paint thinner or similar fluids.
x To help prevent damage to the engine hood and the windshield wiper arms, lift the wiper arms away from the windshield only when they are in the service position.
Cleaning the wind deflector

WARNING
Injuries, scalding, electric shock, accidents, and fire hazards can occur while working on the engine or in the engine compartment!
x Before working in the engine compartment, be sure to familiarize yourself with the necessary procedures and generally accepted safety precautions, Working in the engine compartment.
x Volkswagen recommends having the work performed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
NOTICE
Spraying or pouring water (for example, with a power washer) into the plenum chamber can cause severe damage to the vehicle.
Wash the engine compartment only in special wash bays so that the oily dirt and fuel residue that are washed off the vehicle will not enter the sewage system. In some areas it illegal to wash the engine compartment anywhere other than at such specified locations.

x Accessories and other things installed in front of the cooling air intakes impair the efficiency of the engine coolant. The engine can overheat under high outside temperatures or under high engine loads!
Leaking operating fluids can pollute the environment. Collect leaking operating fluids in suitable containers and dispose of them properly in accordance with applicable environmental laws and regulations.
