differential VOLKSWAGEN JETTA SPORTWAGEN 2013 Owners Manual

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. In certain situations when you need less traction or additional traction
cannot be achieved, you can switch off ASR by pressing the mbutton ⇒ fig. 137. Be sure to switch ASR
on again when you no longer need less traction.
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.
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.
ASR can be switched on or off manually .
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.
