2021 VOLKSWAGEN UP! differential

Driving in the correct gear can reduce fuel consumption.
The display on the gear-change indicator will disappear when the clutch pedal is depressed.
In some vehicles the gear recommendation may be displayed on the screen of the portable
navigation device (delivered by Volkswagen) ⇒ Accessories, modifications, repairs and renewal of
parts.
Braking, stopping and parking
 Introduction
This chapter contains information on the followingsubjects:
⇒ Warning and indicator lamps
⇒ Handbrake
⇒ Parking
⇒ Information on the brakes
⇒ Brake assist systems
⇒ Brake fluid
The brake assist systems are the electronic brake pressure distribution system (EBV), anti-lock
brake system (ABS), the brake assist system (BAS), the electronic differential lock (EDS), traction
control (TC), the traction control system (TCS) and the electronic stabilisation programme (ESC).

The gear-change indicator is only designed to assist the driver and cannot replace the driver's
own judgement.
•The driver has full responsibility for selecting the correct gear in all situations, e.g. when
overtaking or when driving up and down hills.
CAUTION

to assist every time that there is a sudden change in the road surface quality. If a section of dry
road is suddenly covered with water, mud or snow, ESC will not be able to assist in the same
manner as on a dry road. If the vehicle aquaplanes (drives on a layer of water rather than on the
road surface), ESC will not be able to assist in steering the vehicle as the contact to the road
surface has been interrupted and it is therefore no longer possible to steer or brake the vehicle.
Always adapt your speed and driving style to suit visibility, weather, road and traffic conditions. ESC
cannot defy the laws of motion, improve the available power output, or keep the vehicle on the road
if insufficient care and attention on the part of the driver causes the vehicle to leave the road.
Instead, ESC increases the possibility of keeping the vehicle under control and, in extreme on-road
driving situations, it assesses the driver’s steering input and helps the vehicle to continue in the
required direction. If the vehicle is driving at a speed that leads it to leave the road before the ESC
can provide any kind of support, the ESC will be unable to provide any assistance.
The ABS, BAS, TCS and EDL systems are integrated into the ESC. The ESC is always on.
Anti-lock brake system (ABS)
The ABS prevents the wheels from locking when the brakes are applied up until the point where the
vehicle is nearly stationary and assists the driver in steering the vehicle and keeping it under
control. This means that the vehicle is less likely to spin, even when the brakes are depressed fully:
•Depress and hold the brake pedal with force. Do not take your foot off the brake pedal or
reduce the force on the brake pedal!
•Do not pump the brake pedal or reduce the pressure on the brake pedal!
•Steer the vehicle while the brake pedal is fully depressed.
•The ABS will switch off when the brake pedal is released or if the pressure on the brake pedal is
reduced.
If the ABS is taking corrective action, there is a pulsing movement in the brake pedal and some
noise. However, ABS will not necessarily guarantee shorter braking distances in all conditions. The
braking distance could even be longer when braking on gravel or on fresh snow covering an icy or
slippery surface.
Electronic brake pressure distribution system (EBD)
Every vehicle's centre of gravity moves forwards whenever the brake is operated. This means that
the rear wheels are in danger of locking due to the lower traction. The electronic brake pressure
distribution system controls the brake pressure for the rear wheels and thereby ensures the
optimum distribution of brake pressure between the front and rear axles. Under normal conditions,
the system will prevent the rear from breaking away if too much brake pressure if applied to the rear
wheels. The electronic brake pressure distribution system is included in the ABS' scope of
functions.
Brake Assist system (BAS)
The brake assist system can help to reduce the braking distance. The brake assist system
reinforces brake pressure hydraulically when the driver depresses the brake pedal quickly in an
emergency situation. As a result, full braking power is made accessible very quickly, brake pressure
is increased and the braking distance reduced. In this way, the ABS is activated more quickly and
more effectively.
Do not reduce the pressure on the brake pedal. The brake assist system will switch off the
hydraulic brake servo automatically when the brake pedal is released or if the pressure on the
brake pedal is reduced.
Traction Control System (TCS) or Traction Control (TC)
The TCS or TC reduces the engine output if wheelspin occurs and adapts the output to suit road
surface conditions. TCS or TC helps the car to start moving, accelerate and climb gradients in
unfavourable road conditions.
Electronic differential lock (EDL)
The EDL is available for normal driving on straight roads. EDL brakes the wheel that has lost
traction and distributes the driving force to the other drive wheel. To prevent the disc brake of the
braked wheel from overheating, the EDL cuts out automatically if subjected to excessive loads. The
EDL will switch on again automatically when the brake has cooled down.

•You will need to depress the brake pedal more vigorously than normal as the brake servo is not
working. Do not drive too close to the towing vehicle.
•Read and comply with the information and notes in the owner's manual of the towing vehicle.
Notes for the driver of the towing vehicle
•Accelerate carefully and gently. Avoid any sudden driving manoeuvres.
•Brake earlier than normal by pressing lightly on the brake pedal.
•Read and comply with any information and notes in the owner's manual of the towed vehicle.
