light VOLKSWAGEN E GOLF 2015 5G / 7.G Repair Manual

WARNING
Parking improperly can cause serious personal injury.
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.
x Never park the vehicle where the hot exhaust system or catalytic converter could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Always apply the parking brake when parking your vehicle.
x Improper use of the parking brake can seriously injure you and your passengers.
x Never use the parking brake to slow down the vehicle when it is moving, except in an emergency. The stopping distance is much longer because only the rear wheels are braked. Always use the foot brake to stop the vehicle.
x Never leave children or anyone who cannot help themselves behind in the vehicle. They could release the parking brake and move the gear selector lever or gear shift, which could cause the vehicle to start moving. This can lead to a crash and serious personal injuries.
x Always take the key with you when you leave the vehicle. The electric motor can be start-ed and vehicle systems such as the power windows can be operated, leading to serious per-sonal 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, trapping passengers 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 buildup 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.
NOTICE
x Always be careful when you park in areas with parking barriers or high curbs. These vary in height and could damage your bumper and related parts if the front of your vehicle hits a barri-er or curb that is too high while you are getting into or out of a parking spot. To help prevent damage, stop before the tires of your vehicle touch a parking barrier or curb.
x Always be careful when you enter a driveway or drive up or down steep ramps or over curbs or other obstacles. Parts of the vehicle close to the ground may be damaged (such as bumper covers, spoilers, and parts of the electric drive).

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 ⇒ Brake fluid.
x If the brake warning light "2!+% or H lights up 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 rela-tively 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 author-ized Volkswagen dealer or an authorized Volkswagen Service Facility as soon as possible.
x If the brake pads are worn or you notice changes in the way the vehicle brakes, immedi-ately 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.
Warning messages when leaving the vehicle

x The ignition is switched on.
x The vehicle is not drive-ready.
x The driver door is open.
Vehicles with Keyless Access
The crawling function is deactivated if the vehicle has been driven faster than 6 mph (10 km/h) and then comes to a stop. The electric drive is deactivated when the driver safety belt is unlocked and the driver door is opened. If no pedal is pressed, the ignition switches off automatically after about 30 seconds. To avoid unintentional discharge of the 12-volt vehicle battery the ignition is deactivated if the following conditions remain unchanged for about 2 minutes:
x The vehicle is standing still.
x No pedal is pressed.
x The driver safety belt is unlocked.
x The charge level of the 12-volt vehicle battery is low.
Once the ignition has been switched off automatically, the exterior lights remain lit when the light switch is set to AUTO and the charge level is sufficient.
WARNING
A vehicle that is left unattended when ready to drive can cause accidents and serious inju-ries.
x Never leave the vehicle unattended when it is ready to drive.
x Always switch the ignition off and move the selector lever for driving mode to position P, before leaving the vehicle.
x When parking or leaving the vehicle, always ensure that selector lever for driving mode is in position P and that the electric parking brake is switched on.
x When leaving the vehicle always ensure that all doors, windows, the tailgate and bonnet are completely closed and locked.
Electronic parking brake

Fig. 129 In the lower section of the center console: Electronic parking brake button.

Setting the electronic parking brake
You can engage the electronic parking brake any time the vehicle is not moving - even if the ignition is switched off. Always engage the parking brake when you leave or park the vehicle.
x Pull and hold the button ⇒ fig. 129.
x The parking brake is engaged when the indicator light G (arrow) in the button and in the instru-
ment cluster ⇒  Warning and indicator lights lights up.
Releasing the electronic parking brake
x Switch the ignition on.
x Press the button ⇒ fig. 129. At the same time, press the brake pedal firmly or press the accelerator pedal lightly if the electric motor is drive ready.
x The parking brake is released when the indicator light G (arrow) in the button and in the instru-
ment cluster ⇒  Warning and indicator lights goes out.
Releasing the electronic parking brake automatically when you start driving
The electronic parking brake releases automatically when you start driving if the driver's door is closed and the driver's safety belt is buckled.
Emergency braking function
Only use the emergency braking function in an emergency, when you cannot stop the vehicle using
the brake pedal ⇒  !
x Pull and hold the button ⇒ fig. 129 to brake the vehicle hard. An audio warning signal will sound at the same time.
x To stop the braking maneuver, release the button or press the accelerator pedal.
WARNING
Improper use of the electronic parking brake can cause accidents and severe injuries.
x Never use the parking brake to slow down the vehicle when it is moving, except in an emergency. Braking distance is much longer, since only the rear wheels are braked. Alwa ys use the foot brake.
x Never press the accelerator pedal when a selector lever position or gear is engaged and the electric motor is drive ready. The vehicle could begin moving, even if the electronic park-ing brake is set.
NOTICE
Even though the transmission is in Park (P), the vehicle may move a couple of inches (a few centimeters) forwards or backwards if you take your foot off the brake pedal after stopping the vehicle without first firmly setting the parking brake.
If the 12-volt vehicle battery is dead, the electronic parking brake cannot be released.
You may hear noises when setting or releasing the electronic parking brake.
If the electronic parking brake is not used for a while, an automatic system check will occasional-ly run when the vehicle is parked. This system check makes audible noises.

mance 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 endan-
ger 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 light up 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.
Electro-mechanical brake booster
The electro-mechanical brake booster works only when the electric motor is activated. It increases the force on the brakes above and beyond the pressure put on the brake pedal by the driver.
If the electro-mechanical brake booster is not working, 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 185 miles (300 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.

x ABS stops working if you release or let up on the brake.
When ABS is doing its job, you will notice a slight vibration through the brake pedal and hear a noise. ABS cannot shorten the stopping distance under all conditions. The stopping distance may even be longer, for instance, when driving on gravel or on newly fallen snow covering an icy or slip-pery surface.
Brake Assist (BAS)
The Brake Assist System can help to reduce stopping distances. If you press the brake pedal very quickly, BAS detects an emergency situation. It then very quickly builds up full brake system pressure, maximizing braking power and reducing the stopping distance. This way, ABS can be activated more quickly and efficiently.
Do not reduce pressure on the brake pedal! BAS switches off automatically as soon as you release or let up on the brake.
Anti-Slip Regulation (ASR)
ASR reduces electric motor power directed to spinning wheels and adjusts power to the road condi-tions. Even under poor road conditions, ASR can make it easier to get moving, accelerate, and climb hills.
ASR can be switched on or off manually ⇒  Switching Anti-Slip Regulation (ASR) on and off.
Electronic Differential Lock (EDL and XDL)
EDL is applied during regular straight-line acceleration. EDL gently brakes a drive wheel that has lost traction (spinning) and redirects the drive force to other drive wheels. In extreme cases, EDL automat-ically switches off to keep the brake from overheating. As soon as the brake has cooled down, EDL automatically switches on again.
XDL is an extension of the Electronic Differential Lock system. XDL does not react to drive wheel slippage when driving straight ahead. Instead, XDL detects slippage of the inside front wheel during fast cornering. XDL applies enough brake pressure to this wheel in order to stop the slippage. This improves traction, which helps the vehicle stay on track.
WARNING
Driving fast on icy, slippery, or wet roads can lead to a loss of control and result in serious personal injury for you and your passengers.
x Always adjust your speed and driving style to road, traffic, weather, and visibility condi-tions. Never let the additional safety that ESC, ABS, BAS, ASR, and EDL can provide tempt you into taking extra risks.
x Braking assistance systems cannot overcome the laws of physics and always prevent loss of vehicle control. Slippery and wet roads are still dangerous even with ESC and the other systems!
x Driving too fast on wet roads can cause the wheels to lose contact with the road and “hy-droplane.” A vehicle that has lost road contact cannot be braked, steered, or controlled.
x These systems cannot reduce the risk of accident, for example if you drive too fast for conditions or if you do not keep your distance from the vehicle in front of you.
x Although these systems are very effective and can help you control the vehicle in many difficult situations, always remember that your vehicle handling control is limited by tire trac-tion.
x When accelerating on a slippery surface, for example on ice and snow, depress the accel-erator carefully. Even with these systems, the wheels may start to spin, leading to a loss of vehicle control.

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 per-formance, 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 ex-pressly 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 chil-dren.
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.

DANGER
High-voltage systems in the electric motor compartment and in other places on the vehicle can cause electrical shocks or even electrocution, severe burns, other serious injuries, and even death!
x Always assume that the high-voltage battery is fully charged and that all high-voltage components are live.
x Touching damaged orange high-voltage cables, the high-voltage battery or other parts of the high-voltage electrical system can cause fatal electric shock.
x The high-voltage system may also be active even when the ignition is switched off!
x Electrolyte fluid in the high-voltage battery will cause severe chemical burns. If electrolyte fluid contacts skin, thoroughly flush affected area with clean water for at least 15 minutes and then wash affected area with soap and water; medical attention is recommended.
x Never attempt to carry out any work on the high-voltage network, the high-voltage cables or the high-voltage battery.
x Never open, maintain or repair components or parts of the high-voltage network, and nev-er disconnect them from the network.
x Never damage, change or remove the orange high-voltage cables or disconnect them from the high-voltage network.
x Never open, modify or remove the cover of the high-voltage battery.
x Any work on the high-voltage system, or on systems which could be indirectly affected by it, must only be carried out by properly trained and qualified experts.
x Work in the vicinity of high-voltage components and high-voltage cables with machinery, sharp-edged tools or heat sources, for example, welding, soldering, hot air or thermal adhe-sives, may only be performed after the high-voltage components have been disconnected. Only properly qualified and trained specialist staff may work on the high voltage compo-nents.
x The Volkswagen standards and guidelines must be adhered to when carrying out any work on the high-voltage network or the high-voltage battery.
x During such work, keep the vehicle key safe and far enough away from the vehicle to pre-vent any risk of the ignition being accidentally switched on and the electrical system activat-ed (particularly in vehicles with Keyless Access).
x Any gasses emitted by or escaping from the high-voltage battery may be toxic or flamma-ble.
x Damage to the vehicle or to the high-voltage battery could lead to a leak of toxic gases, either immediately or at a later time. These emitted gases could also potentially cause a fire. If damage has been incurred, it is vital to then open the vehicle windows to allow any emitted gases to disperse. Do not inhale these gases.
x Never touch or inhale any liquids or gasses leaking from the high-voltage battery, espe-cially if the battery has been damaged.
x Remember to inform any attending emergency services that the vehicle is equipped with a high-voltage battery.
