slush or snow, ESC cannot perform the same way it would on a dry surface. If the vehicle
“hydroplanes” (rides on a cushion of water instead of the road surface), ESC will not be able to help
you steer the vehicle because contact with the pavement has been interrupted and the vehicle cannot
be braked or steered. During fast cornering, particularly on winding roads, ESC cannot always deal as
effectively with difficult driving situations as it can at lower speeds. When towing a trailer, ESC is not
able to help you regain control as it would if you were not towing a trailer.
Always adjust your speed and driving style to visibility, road, traffic, and weather conditions. ESC
cannot override the vehicle's physical limits, increase the available traction, or keep a vehicle on the
road if road departure is a result of driver inattention. Instead, ESC improves the possibility of keeping
the vehicle under control and on the road during extreme maneuvers by using the driver's steering
inputs to help keep the vehicle going in the intended direction. If you are traveling at a speed that
causes you to run off the road before ESC can provide any assistance, you may not experience the
benefits of ESC.
ESC includes and/or works together with the ABS, BAS, ASR, EDL, and XDL systems (see below).
ESC is switched on all the time and cannot be switched off.
Anti-Lock Brake System (ABS)
ABS helps to keep the wheels from locking up and helps to maintain the driver's ability to steer and
control the vehicle. This means the vehicle is less likely to skid, even during hard braking:
x Push the brake pedal down hard and hold it there. Don't take your foot off the pedal or reduce the
force on the pedal!
x Do not “pump” the brake pedal or let up on it!
x Steer the vehicle while pushing down hard on the brake pedal.
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
slippery surface.
When driving forwards on loose surfaces, a special off-road ABS is automatically activated. In this
mode, the front wheels could lock briefly. This shortens the braking distance in off-road situations as
the wheels dig into loose surfaces. This occurs only when driving straight ahead. When the front
wheels are turned, the normal ABS is activated.
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 engine power directed to spinning wheels and adjusts power to the road conditions.
Even under poor road conditions, ASR can make it easier to get moving, accelerate, and climb hills.
ESC and ASR can help when driving on loose surfaces (such as gravel) and in deep snow. If you get
stuck in deep snow, you may be able to get going again by “rocking” the vehicle back and forth. ESC
and ASR recognize this special driving situation and automatically increase the speed of the front
wheels. Keep pressing the accelerator and let ESC increase the speed of the front wheels to help you
keep moving or get moving again.
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

automatically 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
conditions. 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
“hydroplane.” 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
traction.
x When accelerating on a slippery surface, for example on ice and snow, depress the
accelerator carefully. Even with these systems, the wheels may start to spin, leading to a loss
of vehicle control.
WARNING
The effectiveness of ESC can be significantly reduced if other components and systems that
affect vehicle dynamics, including but not limited to brakes, tires, and other systems
mentioned above, are not properly maintained or functioning.
x Always remember that vehicle alterations or modifications can affect the functioning of
the ABS, BAS, ASR, EDL and ESC systems.
x Changing the vehicle suspension or using an unapproved tire/wheel combination can
change the way the ABS, BAS, ASR, EDL and ESC systems work and reduce their
effectiveness.
x The effectiveness of ESC is also determined by the tires fitted
All 4 wheels must be equipped with identical tires in order for ESC and ASR to work properly.
Differences in the tread circumference of the tires can cause the system to reduce the engine power
when it is not expected.
If ABS is not working, ESC, ASR, and EDL will also not work.
You may hear noises when these systems are active.

Brake fluid specifications
Volkswagen has developed a special brake fluid that is optimized for the brake system in your
Volkswagen. Volkswagen recommends that you expressly use brake fluid that conforms to quality
standard VW Standard 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 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) DOT 4
⇒ .
Please note, however, that not all brake fluids that comply with U.S. Federal Motor Vehicle Safety
Standard FMVSS 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 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 14 or if it is not available, only use a high-quality brake
fluid that conforms to U.S. Standard FMVSS 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 14, or U.S. Standard FMVSS DOT 4, do not use it.
x The brake fluid must be new.
