Trailer Assist
Introduction
This chapter contains information on the followingsubjects:
⇒ Prerequisites
⇒ Operation
⇒ Troubleshooting
Trailer Assist helps the driver when
reversing or manoeuvring the vehicle
when towing a trailer.
The trailer manoeuvring system steers a trailer by adjustment of the rotary knob for the exterior
mirrors. The driver must control the accelerator, gear changes and brake!
System limits
The camera may not always be able to detect objects such as trailer drawbars, thin rails, fences,
posts, trees and open or opening boot lids. This can result in damage to your vehicle.
The camera must be kept clean and free of ice and snow, and must not be covered up by stickers
or other objects, as this will prevent the system from working properly. The drawbar must not be
covered.
Trailer Assist should only be used when the boot lid is fully closed.
The trailer manoeuvring system will be automatically ended around ten minutes after
activation. The function will also be ended if no driver interaction is detected within a period of
approximately three minutes.
Prerequisites
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The following prerequisites must be met for the trailer manoeuvring system to function:
•Engine running.
•ESC is switched on.
•Driver door and boot lid are closed.
•Exterior mirrors are not folded in.
•A single- or- two-axle trailer without steered axles is hitched to the vehicle and electrically
connected.
•Vehicle and trailer are stationary.
•Do not exceed the maximum jack-knifing angle.
•The drawbar length has been determined.
Determining the drawbar length
Trailer Assist requires a few turning and cornering manoeuvres to enable it to determine the length
of the drawbar. The more accurately it can determine the length of the drawbar, the bigger the
angles available when manoeuvring. The trailer manoeuvring system divides the available
maximum limit positions on the angle display into four steps: approx. 30°, 45°, 60° and 75°.
For technical reasons, the trailer manoeuvring system cannot always detect trailers with LED
rear lights correctly.
The trailer manoeuvring system does not use the area around the vehicle for orientation.
No obstacle detection takes place. Drivers must judge for themselves whether the trailer
can be manoeuvred safely.
•Always pay close attention to the movements of the trailer and, if required, stop the
manoeuvre to avoid causing any damage. On rare occasions the trailer may behave
differently, even when Trailer Assist is operated correctly.
•Do not rely only on the displays in the instrument cluster.

Manoeuvring the vehicle and trailer
The checklist conditions are met ⇒ Prerequisites.
•Select reverse gear.
•Press the button.
•Release the steering wheel ⇒.
•Tilt the rotary knob until the desired direction is reached. A representation of the current position
of the vehicle and trailer is shown on the instrument cluster display for orientation
purposes ⇒ Fig. 161.
•Reverse slowly by pressing the accelerator. Check area around vehicle!
•Correct the angle with the rotary knob if necessary. Press the rotary knob to the left and right –
the vehicle combination moves to the left or right. Press the rotary knob to the rear – the vehicle
follows the trailer.
•Reverse and drive forwards until the required position is reached.
•The manoeuvring operation has been completed when a corresponding message is displayed
on the instrument cluster. A signal tone may also sound.
Automatic braking intervention
Trailer Assist helps the driver by initiating an automatic braking intervention in certain situations.
The driver is responsible for braking in time ⇒.
An automatic braking intervention may occur and the function may be cancelled in the following
situations:
•If a certain speed is exceeded.
•If the driver takes hold of the steering wheel. The vehicle is automatically braked to standstill.
•If the button is pressed while manoeuvring or the driver door is opened.
Electronic Stability Control (ESC)
ESC helps to reduce the risk of skidding and to improve driving stability in certain driving situations
⇒.
Depending on the vehicle equipment, ESC can be switched to a Sport mode ⇒ Switching TCS on
and off.
When ESC is regulating, the yellow indicator lamp is shown on the instrument cluster display.
Traction control system (TCS)
The TCS reduces the drive output if wheelspin occurs and adapts the output to suit road surface
conditions. The TCS makes it easier to pull away, accelerate and drive up hills.
Depending on the vehicle equipment, the TCS can be switched off in exceptional circumstances
⇒ Switching TCS on and off.
When the TCS is regulating, the yellow indicator lamp is shown on the instrument cluster
display.
Anti-lock brake system
The anti-lock brake system can prevent 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.
Brake assist system
The brake assist system can help to reduce the stopping distance. The brake assist system
reinforces brake pressure when the driver depresses the brake pedal quickly in an emergency
situation.
Do not reduce the pressure on the brake pedal when the brake assist system is regulating. If you
reduce the pressure on the brake pedal, the brake assist system will switch off the brake servo.
Electronic differential lock (EDL and XDS)
EDL brakes the wheel that has lost traction and distributes the driving force to the other drive
wheels.
The EDL switches off automatically under unusually heavy loads to prevent the disc brake from
overheating. The EDL switches back on again automatically as soon as the brake has cooled down.
XDS applies pressure to the brake of the wheel on the inside of the bend. This will improve traction,
helping the vehicle to remain in the required lane longer.
Automatic Post-Collision Braking System
In the event of an accident, the Automatic Post-Collision Braking System can help the driver to
reduce the risk of skidding, and the danger of secondary collisions, through automatic braking.
The Automatic Post-Collision Braking System functions only in front, side and rear collisions when
the airbag control unit detects a corresponding trigger threshold during the accident.
The ESC brakes the vehicle automatically, provided that the hydraulic braking system, the ESC and
the electrical system are undamaged in the accident and remain functional.
The following actions override automatic braking in the event of an accident:
•When the driver depresses the accelerator. No automatic braking occurs.
•When the brake pressure transmitted through the depressed brake pedal is greater than the
brake pressure provided by the system. The vehicle is braked manually.
Switching TCS on and off
Fig. 162 In the centre console: button for switching TCS on and off manually.
If the vehicle does not have sufficient traction, you can switch off TCS in the following situations:
•When driving in deep snow or on loose surfaces.
•When rocking the vehicle backwards and forwards to free it from mud.
Then switch the TCS function back on.
Switching TCS or ESC Sport on and off
Depending on the vehicle equipment, TCS and ESC Sport can be switched off via the Infotainment
system or using the button ⇒ Fig. 162.
When the TCS is switched off, ESC Sport is switched on, or the Off-road or Off-road Individual
driving profiles are active, the yellow indicator lamp is shown on the instrument cluster display.
The intelligent technology used in brake support systems cannot overcome the laws of
physics, and functions only within the limits of the system. Driving fast on icy, slippery or
wet roads can lead to a loss of control of the vehicle and could cause serious injury to the
driver and passengers.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions. Do not let the extra safety afforded by the brake support systems anti-lock
brake system, brake assist system, EDL, TCS and ESC tempt you into taking any risks
when driving.
•The brake support systems cannot defy the laws of motion. Slippery and wet roads will
remain dangerous, even when the ESC and other systems are active.
•Driving too fast on wet roads can cause the wheels to lose contact with the road
surface and aquaplane. The vehicle cannot be braked, steered or controlled once it has
lost contact with the road surface.
•Brake support systems cannot prevent an accident if e.g. you are driving too close to
the vehicle in front or are driving too fast for the specific driving situation.
•Although the brake support systems are very effective and can help to control the
vehicle in difficult driving situations, please always remember that the driving stability
of the vehicle depends on the tyre grip.
•When accelerating on a slippery surface, e.g. on ice and snow, press the accelerator
carefully. The wheels can spin even when brake support systems are active, and this
can lead to a loss of control of the vehicle.
WARNING
The effectiveness of ESC can be reduced considerably if other components and systems
which affect driving dynamics are not serviced properly or are not functioning properly.
This also applies, but not exclusively, to the brakes, tyres and other systems named
above.
•Please always note that modifications and changes to the vehicle can affect the
function of the anti-lock brake system, brake assist system, TCS, EDL and ESC.
•Alterations to the suspension system or the use of non-approved wheel and tyre
combinations can affect the function of the anti-lock brake system, brake assist
system, EDL, TCS and ESC and reduce their effectiveness.
•Suitable tyres are also crucial if ESC is to function optimally ⇒ Wheels and tyres.
WARNING
Driving without the brake servo can considerably increase the braking distance and thus
cause accidents and serious injuries.
•Never allow the vehicle to roll if the engine is switched off.
•If the brake servo does not function or the vehicle is being towed, the brake pedal will
have to be depressed more forcefully as the braking distance will be increased due to
the lack of assistance for the brake system.

atmosphere. The catalytic converter can also be damaged by overheating.
The emissions may have a sulphur-like smell even if the emission purification system is
working properly.
Particulate filter
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Function
The particulate filter filters out soot particles in the exhaust gas. Observe the following points to
ensure that the exhaust purification system will work properly for a long time:
AdBlue is an irritant and corrosive fluid that can damage the skin, eyes and breathing
passages upon contact.
•Always observe the instructions for use when using AdBlue. If containers are used
according to the instructions, it is unlikely that a user will come into contact with
AdBlue.
•AdBlue must be kept in the closed original container. Never use empty food
containers, bottles or other containers for this purpose.
•Always store in a safe place out of reach of children.
•If AdBlue gets into the eyes, immediately rinse the eyes with plenty of water for at
least 15 minutes and consult a doctor.
•If AdBlue gets onto the skin, immediately wash the area with plenty of water for at
least 15 minutes and consult a doctor if the skin becomes irritated.
•If AdBlue is swallowed, immediately rinse the mouth out with lots of water for at least

Periodic regeneration
The soot in the particulate filter is burnt off at high temperatures on a periodic basis.
To assist the regeneration of the particulate filter, Volkswagen recommends that you avoid making
only short journeys.
Noises, slight smells and increased engine speeds may occur during regeneration. The radiator fan
may run on while the vehicle is moving or when the engine has been switched off.
During the periodic regeneration process, the yellow indicator lamp does not light
up.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Irregular engine running and malfunctions
If the engine shows signs of irregular running or malfunctions while you are driving, this may mean
that the fuel is of poor quality. Reduce speed immediately. Drive to nearest qualified workshop at
medium engine speeds and low loads on the engine.
If these symptoms occur directly after refuelling, switch off the engine immediately to avoid any
subsequent damage. You should obtain professional assistance.
