Braking and parking -> Switching Anti-Slip Regulation (ASR) on and off for Your Volkswagen Passat SUV Seventh Generation (2010-2014)

WARNING  
The effectiveness of ESC can be significantly reduced if other  
components and systems that affect vehicle dynamics, includ-  
ing but not limited to brakes, tires, and other systems men-  
tioned above, are not properly maintained or functioning.  
Always remember that vehicle alterations or modifications  
can affect the functioning of the ABS, BAS, ASR, EDL, and ESC  
systems.  
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.  
The effectiveness of ESC is also determined by the tires fitted  
Tires and wheels.  
All 4 wheels must be equipped with identical tires in order for  
ESC and ASR to work properly. Differences in the tread circumfer-  
ence 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

¤ Please first read and note the introductory information and  
heed the WARNINGS  
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.
