Critical situation. Do not drive on!Possible critical situation.
Detection of a critical situation can also take place acoustically:
A warning signal will sound and a text message will be displayed in the instrument cluster for
vehicles without Park Distance Control.
In vehicles with Park Distance Control, an acoustic signal will sound with the continuous tone of Park
Distance Control. If the Park Distance Control is deactivated, no warning can be given to the driver
and the Rear Traffic Alert system will also be switched off temporarily.
If there is a system fault in the scanned area, the indicator lamp will light up yellow on the
instrument cluster display.
Automatic braking intervention to minimise damage
If Rear Traffic Alert detects an approaching road user and the driver has not pressed the brake, the
system can brake automatically.
Automatic braking intervention is activated when reversing at speeds of between 1 km/h (1
mph). The vehicle is held stationary for up to two seconds after vehicle standstill has been
detected.
After automatic braking intervention is activated to prevent damage to the vehicle, the system
requires approximately ten seconds before it can activate another automatic braking intervention.
Automatic braking intervention can be interrupted by pressing the accelerator or brake pedal
sharply and taking control of the vehicle.
Automatic deactivation
Rear Traffic Alert is deactivated automatically and cannot be switched on if the factory-fitted towing
bracket is electrically connected to a trailer or similar Notes on towing a trailer
electrically connected to the vehicle and the driver pulls away, a text message appears in the
instrument cluster display to inform the driver that Rear Traffic Alert has been deactivated. Rear
Traffic Alert will be automatically activated again when the trailer has been unhitched from the
vehicle. This applies if the functions were previously activated. Rear Traffic Alert must be switched
off manually for trailer towing if a non-factory-fitted towing bracket is used.

WARNING
The intelligent Rear Traffic Alert technology cannot overcome the laws of physics, and functions only
within the limits of the system. Do not let the assistance function of Rear Traffic Alert tempt you to
take any safety risks while driving. The system is not a substitute for the full concentration of the
driver.

Wheels and tyres
Tyre monitoring system
Introduction
This chapter contains information on the followingsubjects:
Tyre Pressure Loss Indicator
Troub
The tyre monitoring system warns the driver when the tyre pressures are too low.
The tyre monitoring system monitors various parameters (for example, rolling circumference) of all
wheels using ABS sensors (indirect measurement).

WARNING
The intelligent tyre monitoring system technology cannot overcome the laws of physics, and
functions only within the limits of the system. Incorrect handling of the wheels and tyres can lead to
a sudden loss of pressure in the tyres, tread separation and even tyre blow-out.

Tyre

Tyre pressure

the cold tyre to the recommended tyre pressure for the tyres installed on your vehicle Tyre
pressure
amage.


If the tyre pressure is too low, this will increase fuel consumption and tyre wear.

When new tyres are driven at high speeds for the first time, they can expand slightly and trigger a
one-off pressure warning.

Old tyres should be replaced only by tyres that have been approved by Volkswagen for the vehicle
type.

Do not rely solely on the tyre monitoring system. Check your tyres regularly to ensure that they are
properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove
any objects that become embedded in the tyre tread but have not penetrated into the body of the
tyre itself.

Functional description
The Tyre Pressure Loss Indicator uses data from the ABS sensors and other functions to compare the
speed of rotation and the rolling circumference of the individual wheels.
The rolling circumference can change:

Engine and transmission guard
An engine and transmission guard can reduce the risk of damage to the vehicle's underbody and
sump, for example when driving over kerbs, drive entrances or unsurfaced roads.
Volkswagen recommends that you have this equipment retrofitted by your Volkswagen dealership.

WARNING
Incorrectly performed repairs and modifications can cause malfunctions and damage to the vehicle
and impair the effectiveness of the driver assist systems. This can result in accidents and severe
injuries.


WARNING
Unsuitable spare parts and accessories, incorrectly carried out work, modifications and repairs can
lead to damage to the vehicle and cause accidents and serious injuries.
Volkswagen Genuine Parts

specifications
Modifications and repairs to the front bumper, doors, front seats, headliner or the bodywork should
be carried out only by a qualified workshop. Airbag system components and sensors might be fitted
on these vehicle components.
If you work on the airbag system or remove and install parts of the system when performing other
repair work, parts of the airbag system may be damaged. The consequence may be that, in the event
of an accident, the airbag inflates incorrectly or does not inflate at all.
Regulations must be observed to ensure that the effectiveness of the airbags is not reduced and that
removed parts do not cause any injuries or environmental pollution. Qualified workshops are
familiar with these regulations.
Any modifications to the vehicle's suspension could prevent the airbag system from working
properly during a collision. For example, using wheel rim/tyre combinations that have not been
approved by Volkswagen, lowering the suspension or making modifications to the suspension rate
including work on the springs, struts and shock absorbers etc., could change the forces that are
measured by the airbag sensors and sent to the electronic control unit. Some changes to the
suspension could cause the forces measured by the sensors to increase, for example. This can lead
to the airbag system being triggered in collision scenarios where it normally would not be triggered if
modifications to the suspension had not been made. Other modifications can cause the forces
measured by the sensors to decrease, therefore preventing the airbag system from being triggered
when it should have been.

WARNING
Incorrect repairs and modifications can cause malfunctions and damage to the vehicle and impair
the effectiveness of the airbag system. This can result in accidents and serious or even fatal injuries.

WARNING
Modifications to the vehicle's suspension, including the use of unsuitable tyre/rim combinations, can
cause the airbag system to function differently and increase the risk of serious or fatal injuries in the
