ESP VOLKSWAGEN BEETLE 2014 3.G Service Manual

Defensive driving and “flowing” with traffic
Frequent braking and acceleration increase fuel consumption significantly. Just by driving defensively and keeping a sufficiently large distance away from the vehicle in front of you can make up for the speed fluctuations caused by taking your foot off the accelerator. Active braking and accelerating is then not necessarily required.
Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical than constantly accelerating and braking. Usually you can reach your destination just as quickly by driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the air conditioner has to produce starkly contrasting temperatures, it requires a large amount of energy, which is generated by the engine. The temperature in the vehicle should therefore not be extremely different from that of the outside temperature. It may be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not running. The transmission will not be lubricated and will be damaged.

WARNING
Rear Assist technology cannot overcome the laws of physics and the limits of the system. Careless or unintentional use of Rear Assist may result in accidents and severe injuries.
x Always adjust your speed and driving style to road, traffic, weather, and visibility conditions.
x Always keep an eye on the parking direction and the vehicle surroundings. The front of the vehicle swings out more than the rear of the vehicle.
x Never pay so much attention to the graphics shown on the screen that you fail to notice what is going on around you.
x Always watch for people, especially small children, animals, and objects, because the camera may not always be able to detect them.
x The system may not be able to clearly show everything behind the vehicle.
x Use Rear Assist only when the rear hatch is completely closed.
NOTICE
x The camera shows only two-dimensional images on the screen. Due to the lack of depth of field, it may be difficult or impossible to identify protruding objects or recesses in the road, for example.
x Things like thin rods, fences, posts, and trees may not be detected by the camera and could damage the vehicle.
Applicable only in the United States
Operation

Fig. 126 In the rear hatch: Location of the Rear Assist camera.

NOTICE
x Things like trailer draw bars, thin rods, fences, trees, narrow painted vertical poles, posts, or a rear hatch that is opening may not be detected by the Park Distance Control sensors and could damage the vehicle.
x If you continue driving closer to an object that the Park Distance Control has already detected and reported, the object may disappear from the sensor range and may no longer be detected. This is especially true for low or high objects. The system will no longer sound warnings about these objects. Ignoring signals from the Park Distance Control system could result in serious damage to the vehicle.
x The sensors in the bumpers can be damaged or become misaligned in low speed impacts and parking maneuvers. Damaged or misaligned sensors cannot accurately detect or report objects that might be within range of the PDC system.
x To help make sure that the system works properly, always keep the sensors in the bumpers clean and free of snow and ice; do not cover the sensors with stickers or other objects.
x When cleaning the sensors with power washers or steam cleaners, only spray the sensors directly for a very short time, and always keep the washer nozzle at least 4 inches (10 cm) from the sensors.
x Noise from rough roads, cobblestones, other vehicles and the surrounding area, for example, can prevent the Park Distance Control system from accurately detecting and reporting people and objects that may be within range of the sensors.
x Aftermarket components such as bicycle racks can impair the function of the Park Distance Control system.
Volkswagen recommends practicing with the Park Distance Control system in a location or parking space with no traffic in order to become familiar with the system and how it works.
Applicable only in the United States
Park Distance Control (PDC)

Fig. 129 In the front bumper: Park Distance Control system sensors.

Switching Park Distance Control back on after it was switched off reactivates the volume. System malfunction warning signals cannot be switched off.
If you manually deactivate the display, PDC remains on and the sound is reactivated.
WARNING
Never rely completely on the PDC for information about people and objects that might be in the way of the vehicle and could be struck by the vehicle causing serious personal injury.
x The PDC sensors have blind spots where they cannot detect people or objects.
x Always watch for people, especially small children and animals, because the sensors may not always be able to detect them.
If you hear a long beep lasting about 3 seconds when you first turn PDC on or the indicator light in the button starts blinking, this means there is a malfunction in the Park Distance Control system. Switch off the Park Distance Control system with the button and have it immediately checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.

WARNING
Even if empty, portable fuel containers can leak and cause a fire and serious personal injuries, especially in a crash.
x For your safety, we strongly recommend that you do not travel with a portable fuel container in your vehicle.
x If, under exceptional circumstances, you must transport a portable fuel container, please observe the following:
– Never fill a portable fuel container while it is anywhere in or on the vehicle (for example, in the luggage compartment or on top of the rear hatch). Static electricity can build up while filling and can ignite fuel vapors, causing a fire.
– Always place a portable fuel container on the ground before filling. Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable.
– Always keep the filler nozzle completely inside the portable container before and during filling.
– If filling a portable container made of metal, the filler nozzle must always be in contact with the container. This will help prevent static electricity from discharging and causing a fire.
– Always observe local and state or provincial laws about the use, storage, and transportation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as ANSI/ASTM F852-86.
NOTICE
x Remove fuel spills from the vehicle immediately to help prevent damage to the paint, tires, and wheel housings.
x Refueling with gasoline when your vehicle has a diesel engine or refueling with diesel fuel when your vehicle has a gasoline engine can cause very serious and expensive engine and fuel system damage that is not covered by any Volkswagen Limited Warranty.
x If you put any amount of incorrect fuel in the fuel tank, do not start the engine under any circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance. These fuels contain substances that can severely damage the fuel system and the engine if the engine is started.
x Vehicles with diesel engines must never be refueled or driven with gasoline, kerosene, heating oil, or other non-specified fuels that have not been expressly approved for use with the diesel engine. Other kinds of fuel will cause serious damage to the fuel system and the engine that is not covered by any Volkswagen Limited Warranty.
Fuels can pollute the environment. Spilled fuel must be collected and disposed of properly, following all applicable environmental regulations.
There is no emergency release for the fuel filler flap. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility for assistance.

WARNING
Driving with a fuel tank that is almost empty can lead to stalling in traffic, a collision, and serious personal injuries.
x When the fuel tank is almost empty, fuel supply to the engine can be interrupted, especially when driving over bumps, across slopes, and up and down hills.
x Steering and braking assistance as well as ESC and related systems will not work if the engine “sputters” or stalls due to lack of fuel.
x Always refuel when the tank is 1/4 full to reduce the risk of running out of fuel and stalling in traffic.
NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x Never drive until the fuel tank is completely empty. The irregular fuel supply can cause the engine to misfire. This allows unburned fuel to get into the exhaust system and damage the catalytic converter or the diesel particulate filter.
The small arrow next to the gas pump symbol in the fuel gauge shows the side of the vehicle with the fuel filler flap.
Refueling

Fig. 135 Fuel cap placed on the open fuel filler flap.

The fuel filler neck of diesel vehicles is equipped with a misfueling guard ⇒ fig. 136. The misfueling guard helps prevent filling the fuel tank of a diesel vehicle with gasoline, because the guard makes it difficult to insert any type of filler nozzle other than the type commonly used for diesel fuel.
Damaged, worn out, or incorrect nozzles, as well as other means of refueling (portable fuel containers, for example) will generally not open the misfueling guard and fuel from these sources cannot easily flow into the tank. Using these incorrect or non-standard nozzles to refuel your diesel vehicle can cause fuel spills, which can cause fires, explosions, burns, and other severe injuries.
The misfueling guard can generally only be properly opened with a correct nozzle from a standard diesel fuel pump. Under certain circumstances it may be necessary to turn the nozzle back and forth slightly with light pressure to open the misfueling guard. If the misfueling guard cannot be opened this way, see the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility and have the fuel system checked.
WARNING
Spilled fuel can cause fires, explosions, burns, and other severe injuries.
x Do not refuel from devices other than correct, undamaged standard diesel fuel pump nozzles.
x Always stop refueling once the pump nozzle switches off so that the tank does not overflow.
NOTICE
x It is your responsibility to put the right fuel in your vehicle and any damage that results from using the wrong fuel is not covered under the Emissions warranties or any other Volkswagen Limited Warranty.
x If you put any amount of the wrong fuel in the fuel tank, do not start the engine under any circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic part. Wash the contaminated vehicle parts right away with soap and warm water to help prevent leaks and serious damage.
NOTICE
Never force a fuel nozzle in the diesel misfueling guard. Forcing a fuel nozzle in the misfueling guard can damage it so that it can no longer help prevent misfueling.
x If you have problems inserting a diesel fuel nozzle, please check to make sure you are using the right kind of diesel fuel.
x If you must refuel with a non-standard diesel fuel nozzle, an adapter is available from Volkswagen to allow refueling. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance. Only use an adapter approved by Volkswagen for your vehicle.
Fuel capacities

The recommended gasoline octane rating for your engine is listed on a label inside of the fuel filler flap. This rating may be specified according to AKI (CLC) or RON (ROZ) standards.
If unleaded Premium grade gasoline is specified for your vehicle, then Volkswagen recommends using TOP TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95 RON). For more information on TOP TIER Detergent Gasoline, please go to the official Web site, http://www.toptiergas.com.
The gasoline grades most commonly sold in the United States and Canada have the following octane ratings, which can usually be found on the filler pump:
x Premium grade: 91 to 96 AKI
x Regular grade: 87 to 90 AKI
Unleaded gasoline
Unleaded gasoline is available throughout the USA and Canada. Volkswagen recommends that you do not take your vehicle to places where unleaded gasoline may not be available.
Gasoline containing alcohol or MTBE
You may use unleaded gasoline blended with alcohol or MTBE (methyl tertiary butyl ether), commonly referred to as oxygenated fuels, if the blended mixture meets the following criteria:
Blends of gasoline and methanol (wood alcohol or methyl alcohol):
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 3% methanol.
x Blend must contain more than 2% co-solvents.
Blends of gasoline and ethanol (grain alcohol or ethyl alcohol):
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 10% ethanol.
Blends of gasoline and MTBE:
x Anti-Knock Index (AKI) must be 87 or higher.
x Blend must contain no more than 15% MTBE.
Seasonally adjusted gasoline
Many fuels are blended especially for winter or summer conditions. When seasons change, Volkswagen suggests that you buy fuel at busy stations where the seasonal adjustment is more likely to be made earlier.
WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.
NOTICE
x Never use fuel with an octane rating lower than 87 AKI/91 RON. Using lower octane fuel may cause expensive engine damage.
x Never use leaded gasoline! Leaded gasoline will severely damage your vehicle's catalytic converter.
x Methanol-blended fuels that do not meet the criteria listed above may cause corrosion and may damage plastic and rubber parts in the fuel system.

x Never use fuels that contain lead or other metals (check listing on the fuel pump). Even lead replacement gasoline (LRP fuels) contain metallic additives in high concentrations. They can damage the engine.
x Do not use fuels that fail to meet the criteria above, or with contents that cannot be identified.
x If you cannot tell whether a particular fuel blend meets the criteria above, ask your service station or its fuel supplier. If you notice a loss of fuel economy or drivability and performance problems using one of these fuel blends, we recommend that you switch to unblended fuel.
x Using fuels that are different from those specified above can damage your vehicle's engine and fuel system and cause performance problems.
x Damage to the engine and fuel system and performance problems caused by using fuels that are different from those specified above or by using “starting assist fluids” are not the responsibility of Volkswagen and are not covered under the Emission warranties or any other Volkswagen Limited Warranty.
Even a single tank full of leaded fuel can do major damage to the catalytic converter and degrade its effectiveness in reducing polluting emissions.
If you notice a loss of fuel economy or drivability and performance problems using one of these fuel blends, we recommend that you switch to unblended fuel. Never use fuel line antifreeze offered for gasoline engines.
Gasoline additives

Using diesel fuel with concentrations of methyl ester biodiesel higher than 20 % (B20), such as B100 is still contrary to the terms of your Emission warranties or any other Volkswagen Limited Warranty and remains strictly prohibited.
Biodiesel blends (up to B20) may be used in your Illinois registered TDI® Clean Diesel vehicle; however, please be aware that biodiesel has characteristics that are different from other kinds of fuel, especially petroleum-based fuels.
Biodiesel can attract water and also deteriorate with age. Small amounts of biodiesel can get into the engine oil, but unlike petroleum diesel, it does not evaporate over time. This can cause the oil level in the engine to rise and can affect the quality of the oil.
x Routinely check the engine oil level. A good time to do this is when you refuel, especially if you regularly do a lot of short distance or stop-and-go driving. This will help you see if the engine oil level is getting higher. (A rising oil level beyond the maximum indicator means an oil change is needed due
to the dilution of the oil in the system; a potential characteristic of biodiesel use) ⇒ page 280, Engine oil.
x If you ever notice that the engine oil level has risen or is above the maximum indicator, contact your authorized Volkswagen dealer, authorized Volkswagen Service Facility or Volkswagen Customer CARE to schedule an oil change – regardless of the time or mileage that has elapsed since you last had an oil change performed.
x Continue to follow the oil change intervals found in the Warranty and Maintenance booklet that came with your vehicle, and use only engine oil that expressly complies with Volkswagen quality standard VW 507 00.
x Refuel only at trusted, commercial fueling stations that are located near main highways. These stations are more likely to have “fresh” biodiesel fuels that have not aged significantly.
x If your vehicle will be in storage (or not driven) for several weeks or months, please completely fill the fuel tank. If possible, fill the tank with Ultra Low Sulfur Diesel fuel [ASTM D-975 standard Grade No. 2-D (S15)].
