lane assist 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.

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.

Checklist
For your own safety and that of your passengers, carry out the following steps in the order listed ⇒ :
1. Park the vehicle at a safe distance from traffic and on a suitable surface ⇒ .
2. Switch on emergency flashers by pressing the  switch ⇒ fig. 172.
3. Apply the parking brake to help prevent the vehicle from moving .
4. Shift the transmission into Park (P) (automatic) or Neutral (manual only) .
5. Stop the engine and remove the key from the ignition switch .
6. Have all passengers exit and go to a safe location away from moving traffic, such as behind a
guard rail.
7. Take all vehicle keys with you when leaving your vehicle.
8. Set up a warning triangle or other warning device in order to alert other motorists and cyclists.
9. Let the engine cool down and get expert assistance if necessary.
If the emergency flashers are on, use the turn signal lever to indicate a direction or lane change, for
example when the vehicle is being towed. This temporarily interrupts the emergency flashers.
Switch on the emergency flashers when:
x Traffic suddenly slows down or stops in front of you to warn those approaching from behind.
x In any emergency situation.
x If the vehicle breaks down.
x When being towed.
Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to
alert other motorists and cyclists to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common
sense.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot.
They can cause fires and serious personal injury.
x Never park where parts of the hot exhaust system or catalytic converter could ignite
flammable materials, such as dry grass, brush, leaves, spilled fuel, etc.
The vehicle battery will be drained if the emergency flashers are on for a long time – even if the
ignition is switched off.
