service VOLKSWAGEN EOS 2015 1.G Workshop Manual

WARNING
Incorrect tire pressures and/or underinflated tires can cause sudden tire failure, loss of control, collision, serious personal injury or even death.
x When the warning symbol appears in the instrument cluster, stop and inspect the tires.
x Incorrect tire pressure and/or underinflated tires can cause increased tire wear and can affect the handling of the vehicle and stopping ability.
x Incorrect tire pressures and/or underinflated tires can also lead to sudden tire failure, including a blowout and sudden deflation, causing loss of vehicle control.
x The driver is responsible for the correct tire pressures for all tires on the vehicle. The
recommended tire pressure values are listed on a sticker inside the driver door ⇒  Tire inflation pressure.
x The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire inflation pressure specified for the tires installed on the vehicle.
x Using incorrect tire pressure values can cause accidents or other damage. Always inflate the tires to the correct specified cold tire pressure values for the tires installed on the vehicle.
x Always maintain correct cold tire inflation pressure so that TPMS can do its job.
x Always inflate tires to the recommended and correct tire pressure before driving off.
x Driving with underinflated tires causes them to flex (bend) more, letting them get too hot, resulting in tread separation, sudden tire failure and loss of control.
x Excessive speed and/overloading can cause heat build-up, sudden tire failure, and loss of control.
x If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well.
x If the tire is not “flat” and you do not have to change a wheel immediately, drive carefully and at reduced speed to the nearest service station to check the tire pressure and add air as required.
x When replacing tires or wheel rims on vehicles equipped with TPMS always read and heed
the information and all WARNINGS regarding Tires and wheels ⇒  Tires and wheels.
NOTICE
x The wheel electronics are attached to special aluminum valves on the wheels. These valves are screwed on rigidly. Never bend the valves “into position” when checking and adjusting tire pressure.
x Missing valve stem caps can cause damage to the valves as well as to the TPMS sensors. To help prevent damage, always use valve stem caps like those originally installed at the factory. The caps must be screwed on tightly. Do not use metal valve stem caps.
x Do not use “comfort valve caps.” They do not seal properly and can damage the sensors.
x When replacing or rotating tires, make certain the valves and sensors are not damaged.
x The aluminum valves that are installed should be replaced after about 6 years of use because of aging in the rubber seals. The valves can be replaced when a tire is changed. Do not reuse aluminum valves after they are removed. They must be replaced. The tire pressure sensor can be reused.
x When replacing the valve cores, use only nickel-plated replacement cores.
x The batteries in the wheel electronics last up to 10 years. It is not possible to replace the batteries. The entire device must be replaced.
Underinflated tires increase fuel consumption and tire wear.

Dispose of the wheel electronics and the old batteries in an environmentally responsible manner. Batteries of the type used in the wheel electronics may contain Perchlorate Material. Special handling may apply. See www.dtsc.ca.gov/hadardouswaste/perchlorate. Obey all applicable legal requirements regarding proper disposal.
Do not rely only on the Tire Pressure Monitoring System. Check your tires regularly to make sure they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove any objects that become embedded in the tire tread but have not penetrated into the body of tire itself.
The Tire Pressure Monitoring System checks for the factory-recommended inflation pressure, as
shown on the label inside the driver door ⇒  Tire inflation pressure.
x For replacement tires that require a different inflation pressure, the TPMS must be adjusted to the new pressure specification by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Only one value can be entered for each tire; see the tire inflation pressure label on the driver
door pillar ⇒  Tire inflation pressure.
x To help prevent damage to the sensor and valve, do not put excessive force on the valve when checking the tire pressure. Do not try to bend the valve.
x If sensors have to be replaced, have the valves changed at the same time.
x The tire valve gaskets must be replaced whenever a tire is mounted on the rim. Your authorized Volkswagen dealer or authorized Volkswagen Service Facility has a valve seal and gasket kit for this purpose. Always make sure that a valve seal and gasket kit is also used whenever a sensor is replaced.
x If you have to adjust the tire pressure on a “warm” tire, fill the tire with 2.0 - 4.35 psi (20 - 30 kPa) more than the pressure specified on the tire pressure label.
x When the TPMS determines that the air pressure in at least one tire is too low, carefully check the pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be determined by looking at the tire. This is especially true of low-profile tires.
A Declaration of Compliance with the United States FCC and Industry Canada regulations is
found in the Consumer Information section of this Manual ⇒ page 336, Declaration of Compliance, Telecommunications and Electronic Systems.
There may be differences between the pressure readings from a tire pressure gauge and the pressures registered by the Tire Pressure Monitoring System. The electronic TPMS is more accurate.
If you have work done on your wheels or tires, inform the workshop that the vehicle is equipped with a Tire Pressure Monitoring System that has sensors in the wheels.
Indicator light (telltale)

Emergency shift program
If all selector lever position indicators in the instrument cluster display are highlighted against a bright background, there is a system malfunction. The automatic transmission and the DSG automatic transmission will then operate in the emergency shift program. The emergency shift program lets you drive the vehicle, but at a reduced speed and without being able to use all of the forward gears.
In some cases, vehicles with a DSG® Direct Shift Gearbox automatic transmission may not be able to shift into reverse. It is then impossible to drive the vehicle backwards.
In any event, have the automatic transmission checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Overheating of Direct Shift Gearbox (DSG®) automatic transmission
The DSG® automatic transmission may overheat, for example, due to frequent starts, extended “creeping,” or stop-and-go traffic. Overheating is indicated by the warning light

Lights up Possible cause Proper response
D
Power steering assist is reduced.
Stop, restart the engine, and drive a short distance. If the yellow warning light does not come on again, you do not need to have the steering system checked. Otherwise, have the steering checked immediately by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Vehicle battery was disconnected and has been reconnected. Drive a short distance at about 10–12 mph (15–20 km/h).


Flashes Possible cause Proper response
D Electronic steering column lock malfunction.

Flashes Possible cause Proper response
K The release button in the selector lever is not engaged. Engage the Automatic Shift Lock (ASL)

When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.
WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
WARNING
Driving with bad brakes can cause a collision and serious personal injury.
x If the brake warning light "2!+% or H does not go out, or lights up when driving, either the brake fluid level in the reservoir is too low or there is a fault in the brake system. Stop the
vehicle as soon as you can do so safely and get expert assistance ⇒ page 240, Brake fluid.
x If the brake warning light "2!+% or H comes on at the same time as the ABS warning light !"3 or J, the ABS may not be working properly. This could cause the rear wheels to lock up relatively quickly during braking. Rear wheel brake lock-up can cause loss of vehicle control.
x If you believe the vehicle is safe to drive, drive slowly and very carefully to the nearest authorized Volkswagen dealer, authorized Volkswagen Service Facility, or other qualified workshop and have the brake system inspected. Avoid sudden hard braking and steering.
x If the ABS indicator light !"3 or J does not go out, or if it lights up while driving, the ABS system is not working properly. The vehicle can then be stopped only with the standard brakes (without ABS). You will not have the protection ABS provides. Contact your authorized Volkswagen dealer or an authorized Volkswagen Service Facility as soon as possible.
x If the symbol "2!+% 7%!2 or I lights up in the instrument cluster display, whether alone or together with a text message, immediately contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility to have the brake pads checked and, if necessary, replaced.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.

New brake pads do not provide full performance during the first 100 to 200 miles (200 to 300 km) and
must first be “broken” in ⇒ . To some extent, you can make up for the somewhat reduced performance by applying more pressure to the brake pedal. But, during the break-in period, the stopping distance for hard braking and emergency braking will be longer until the brakes are fully broken in. Avoid hard braking and situations that might require hard braking (such as following other vehicles too closely) – especially during the break-in period.
Brake pad wear depends mostly on operating conditions and the way the vehicle is driven. If you do a lot of city and short-distance driving and/or have a sporty driving style, you should have the brake pads checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility more often than the regular service intervals.
Wet brakes (for example, after driving through water or washing the vehicle or after heavy rainfall) will not brake as well. Stopping distances will be longer when brake discs are wet or, in winter, even icy. Wet or icy brakes must be dried as soon as possible by carefully applying the brakes a couple of times while traveling at a relatively high speed. Make sure nobody is behind you and that you do not
endanger yourself or others ⇒ .
Brakes coated with road salt also react slower and need longer stopping distances. If there is salt on the roads and you are not braking regularly, brake carefully and gently from time to time to remove any
salt coating from the brake discs and pads ⇒ .
Brake disc corrosion (rust) and dirt buildup on the brake pads are more likely to occur if the vehicle is not driven much or is driven only for short distances with little braking. If the brakes have not been used and there is some rust on the discs, clean the brake discs and pads once in a while by carefully braking a couple of times while driving at relatively high speed to help clean the brake discs and pads.
Make sure nobody is behind you and that you do not endanger yourself or others ⇒ .
Brake system malfunction
If you brake and find that the vehicle doesn't brake nearly as well as it used to (sudden increase in stopping distance), a brake circuit may have failed. The brake warning light H or "2!+% will come on and a message may appear in the instrument cluster display. If you believe the vehicle is safe to drive, immediately take it to the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for repair. Drive slowly and very carefully, allow for the longer stopping distance, and be ready to push longer and harder on the brake pedal to slow the vehicle down.
Brake booster
The brake booster works only when the engine is running. It increases the force on the brakes above and beyond the pressure put on the brake pedal by the driver.
If the brake booster is not working, or if the vehicle has to be towed, you will have to push the brake pedal harder to make up for the lack of booster assistance and the resulting longer stopping distance
⇒ .
WARNING
New brake pads do not provide maximum braking performance.
x New brake pads do not have the best stopping power for the first 200 miles (320 km) and must be “broken in.” You can compensate for the slightly reduced braking force by putting more pressure on the brake pedal.
x Drive with extra care while the new brake pads are being broken in. This reduces the risk of collisions and serious personal injuries due to a loss of control over the vehicle.
x Never follow other vehicles too closely or put yourself into other situations that might require sudden, hard braking, especially when the brake pads have not been broken in.

WARNING
Overheated brakes will reduce the vehicle's stopping power and increase stopping distances considerably.
x When driving downhill, the brakes have to work especially hard and heat up quickly.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and shift into lower gear (manual or automatic transmission). This will let the vehicle use engine braking and reduce the load on the brakes. Otherwise, the brake system could overheat and possibly fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
x A damaged front spoiler or a non-standard spoiler can reduce airflow to the brakes and make them overheat.
WARNING
Wet brakes or brakes coated with ice or road salt react slower and need longer stopping distances.
x Carefully apply the brakes to test them.
x Always dry brakes and clean off ice and salt coatings with a few cautious brake applications when visibility, weather, road and traffic conditions permit.
WARNING
Driving when the brake booster is not working increases stopping distances and can cause accidents and serious personal injuries.
x Never let the vehicle coast when the engine is switched off.
x If the brake booster is not working (such as when the vehicle is being towed), a lot more pedal force is needed to slow down and stop.
NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to brake. Constant pressure on the brake pedal can make the brakes overheat. Riding the brakes will substantially reduce braking performance, increase stopping distance, and can cause complete brake system failure.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and shift into lower gear (manual or automatic transmission). This will let the vehicle use engine braking and reduce the load on the brakes. Otherwise, the brake system could overheat and possibly fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
When the front brakes are serviced, you should have the rear brake pads inspected at the same time. The wear of all brake pads should be visually checked regularly. The best way to check for brake pad wear is to have your authorized Volkswagen dealer or authorized Volkswagen Service Facility visually inspect the pads through the openings in the wheel rims or from underneath the vehicle. If necessary, the wheels can be taken off for a more thorough inspection.

Brake fluid absorbs water from the air over time. Too much water in the brake fluid will damage the brake system. Water also lowers the boiling point of the brake fluid. Too much water in the brake fluid can cause vapor lock during heavy brake use or hard braking. Vapor lock reduces braking performance, increases stopping distances and can even cause total brake failure. Your safety and
the safety of others depends on brakes that are working properly at all times ⇒ .
Brake fluid specifications
Volkswagen has developed a special brake fluid that is optimized for the brake system in your Volkswagen. Volkswagen recommends that you use brake fluid that expressly conforms to quality standard VW Standard 501 14 for optimum performance of the brake system. Check the information on the container for the brake fluid you want to use to make sure it meets the requirements for your vehicle.
Brake fluid that complies with VW Standard 501 14 can be purchased from your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
If this special brake fluid is not available you may – under these circumstances – use another high quality brake fluid that complies with U.S. Federal Motor Vehicle Safety Standard (FMVSS) 116 DOT 4
⇒ .
Please note, however, that not all brake fluids that comply with U.S. Federal Motor Vehicle Safety Standard FMVSS 116 DOT 4 have the same chemical composition. Some of these brake fluids can contain chemicals that could, over time, degrade or damage internal parts of the vehicle’s brake system.
Volkswagen therefore recommends that you use brake fluid that expressly complies with VW Standard 501 14 for optimum brake system performance over the long term.
Brake fluid level
The fluid level in the transparent brake fluid reservoir must always be between the MIN and MAX
marking ⇒ .
On some vehicles, engine components block the view of the brake fluid reservoir and make it impossible to see the brake fluid level. If you cannot clearly see the brake fluid level in the brake fluid reservoir, please see an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
The brake fluid level drops slightly when the vehicle is being used as the brake pads wear and the brakes are automatically adjusted.
Changing brake fluid
Brake fluid must be changed according to the service schedule in your ⇒ Booklet Warranty and
Maintenance. Have the brake fluid checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Refill only with new brake fluid that meets the standards listed above.

WARNING
Brake failure and reduced brake performance can be caused by not having enough brake fluid in the reservoir or by old or incorrect brake fluid.
x Check the brake system and brake fluid level regularly.
x Always change the brake fluid according to the service schedule in your
⇒ Booklet Warranty and Maintenance.
x Hard braking with old brake fluid may cause vapor lock. Vapor lock reduces braking performance, increases stopping distances and can even cause total brake failure.
x Always make sure that only the correct brake fluid is used. Only use brake fluid that expressly conforms to VW Standard 501 14 or, if it is not available, only use a high-quality brake fluid that conforms to U.S. Standard FMVSS 116 DOT 4 requirements.
x Using another brake fluid, or one that is not of high quality, can impair the function of the brake system and reduce its effectiveness. If the container does not say that the brake fluid complies with VW Standard 501 14, or U.S. Standard FMVSS 116 DOT 4, do not use it.
x The brake fluid must be new.
WARNING
Brake fluid is poisonous.
x To reduce the risk of poisoning, never use food, beverage or other non-original containers to store brake fluid. Someone might be misled by the original label on the container, or by the shape of the container, and drink the brake fluid. This could occur even if you relabel the container as “brake fluid.”
x Only store brake fluid in the closed, original container and keep it out of the reach of children.
NOTICE
Brake fluid will damage vehicle paint, plastic parts, and tires. Wipe any brake fluid off vehicle paint and other vehicle parts immediately.
Brake fluid can pollute the environment. Brake fluid that has leaked out must be collected and disposed of properly, following all applicable environmental regulations.
