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.
NOTICE

•Switch off TCS: press the button for around one second.
•Switch on ESC Sport: press the button for longer than three seconds.
•Switch on TCS: press the button again. ESC Sport is switched off.
Troubleshooting
Warning and indicator lamps in the event of faults
Do not drive on! Brake system fault. Seek expert assistance immediately ⇒.Lit
up: ABS failure or defect. Go to a qualified workshop. The vehicle can be braked without ABS.
Lit up: ESC switched off by the system. Switch the ignition on and off. Drive a short distance at a
speed of 15 – 20 km/h (9 – 12 mphyfLIQHFHVVDU\,I still lights up, seek expert assistance.
Notes on the brake support systems
If you suspect that there is a malfunction in the systems, read and observe the following notes:
•The ESC and TCS can function properly only if all four wheels are fitted with the same tyres.
Any differences in the rolling radius of the tyres can cause the system to reduce engine power
unexpectedly.
•If there is a fault in the anti-lock brake system, the ESC, TCS and EDL will also stop working.
•Operating noises may be heard during the self-regulation processes of the systems explained
above.
Practical equipment
Stowage areas
Introduction
This chapter contains information on the followingsubjects:
⇒ Stowage compartment on the driver side
⇒ Stowage compartment on the front passenger side
⇒ Stowage compartment in the dash panel
⇒ Stowage compartment in the front centre armrest
⇒ Stowage compartment in the roof console (glasses compartmentyf
⇒ Folding table
⇒ Drawers
⇒ Coat and bag hooks
Use stowage compartments only to stow light or relatively small objects.
A factory-fitted CD changer, Apple iPod adapter, USB connection or multimedia socket
(MEDIA-INyf may be located in the stowage compartment in the centre armrest.
•If the brake warning lamp lights up together with the ABS indicator lamp , the
control function of the anti-lock brake system may have failed. This can cause the rear
wheels to lock quickly when you brake. Locked rear wheels can lead to a loss of
control of the vehicle. If possible, reduce your speed and drive carefully at low speed
to the nearest qualified workshop in order to have the brake system tested. Avoid
sudden braking and driving manoeuvres on the way.
•The anti-lock brake system is not functioning correctly if the ABS indicator lamp
does not go out or comes on while the vehicle is in motion. The vehicle can be stopped
using the normal brakes only (without the anti-lock brake systemyf7KHSURWHFWLRQ
provided by the anti-lock brake system is no longer available. Go to a qualified
workshop as soon as possible.
WARNING
®

•If necessary, fold back the rear seat backrest and allow it to engage securely.
•If necessary, adjust the headlight range ⇒ Headlights.
•Adjust the tyre pressure according to the vehicle load. Observe the tyre pressure sticker ⇒ Tyre 
pressure.
•In vehicles with a tyre monitoring system, set the new vehicle load level as necessary ⇒ Tyre 
monitoring systems.
Do not cover the ventilation openings in the area around the rear window as this prevents
stale air escaping from the vehicle.
Luggage compartment cover
Fig. 181 In the luggage compartment: removing and installing the luggage compartment cover.
Objects that are not secured, or are secured incorrectly, can cause serious injuries in the
event of a sudden driving or braking manoeuvre or accident. This applies particularly if
objects are struck by the airbag when activated and then flung through the vehicle
interior. To reduce the risk of accidents, please observe the following guidelines:
•Always stow all objects in the vehicle securely.
•Small and light objects should also be secured.
•Objects should be stowed in the vehicle interior in such a way that they can never
enter the airbag deployment zones while the vehicle is in motion.
•Always keep stowage compartments closed while the vehicle is in motion.
•Stowed objects must never cause passengers to assume an incorrect sitting position.
•If an item is being stowed on a seat, this seat must not be used by any passengers.
•Do not stow any hard, heavy or sharp objects loose in any of the vehicle's open
stowage areas, on the surface behind the rear seat backrest or on the dash panel.
•Remove any hard, heavy or sharp objects from items of clothing and bags inside the
vehicle and stow them securely.
WARNING
Transporting heavy objects changes the vehicle's handling and increases the braking
distance. Heavy loads that are not properly stowed or secured in the vehicle can lead to a
loss of vehicle control and can cause serious injury.
•Never exceed the vehicle's maximum payload. Both the payload and the distribution of
the load in the vehicle will have an effect on the driving response and braking distance
of the vehicle.
•Transporting heavy objects changes the vehicle's handling and the centre of gravity.
•The payload should be distributed as evenly as possible in the vehicle.
•Always secure heavy objects in the luggage compartment as far in front of the rear axle
as possible.
•Loose objects in the luggage compartment can suddenly slide and change the way the
vehicle handles.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
•Accelerate carefully and gently.
•Avoid sudden braking and driving manoeuvres.
•Brake earlier than in normal driving.
WARNING
Objects rubbing against the rear windows may damage or destroy the heating wires or,
depending on the vehicle equipment, also the aerial.
NOTICE

Driving with a trailer not only places an extra load on the vehicle, but also requires increased
concentration on the part of the driver.
Vehicles with start/stop system
If the connected trailer is not recognised, or when using towing brackets that were not retrofitted by
Volkswagen, the start/stop system must be deactivated manually using the button in the
centre console before starting to tow a trailer, and must remain switched off for as long as the trailer
is being towed ⇒.
Always switch off the anti-theft alarm before a trailer is hitched or unhitched or a bicycle
carrier is loaded or unloaded ⇒ Central and manual locking. The tilt sensor could otherwise trigger
an alarm unintentionally.
With a new engine, do not tow a trailer during the first 1,000 km ⇒ Running in the engine.
Some retro-fitted towing brackets may cover the aperture for fitting the towing eye. If so, the
towing eye cannot be used for towing or tow-starting other vehicles. For this reason, the retro-fitted
towing bracket ball head should be stored in the vehicle at all times.
It is dangerous to transport people in a trailer and it may also be illegal.
DANGER
Improper use of the towing bracket can lead to a loss of vehicle control, accidents and
serious injuries.
•Only use the towing bracket if it is fitted properly and is not damaged.
•Do not carry out any alterations or repairs to the towing bracket.
•Wherever possible, swivel in or remove the ball head when a trailer is not being used in
order to reduce the risk of injury in rear-end collisions, and the risk of injury to
pedestrians and cyclists when the vehicle is parked.
•Never install a weight-distributing or load-balancing towing bracket to the vehicle. The
vehicle is not constructed for these kinds of towing brackets. The towing bracket can
fail, causing the trailer to tear loose from the vehicle.
WARNING
Towing a trailer and transporting heavy or bulky items can change the vehicle handling,
increase the braking distance and lead to accidents.
•Always secure loads properly using suitable and undamaged securing straps.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions. Reduce your speed, particularly when going downhill.
•Trailers with a high centre of gravity are more likely to tip over than trailers with a low
centre of gravity.
•Always drive carefully and think ahead. Accelerate carefully and gently. Avoid abrupt
and sudden driving and braking manoeuvres.
•Take special care when overtaking. Reduce your speed immediately if the trailer shows
even the slightest sign of snaking.
•Never drive faster than 80 km/h (50 mphyfZKHQWRZLQJDWUDLOHUDOVRNPKPSK\f
in exceptional cases. This also applies to countries where higher speeds are permitted.
Keep to country-specific speed limits which may be lower for vehicles with trailers than
for vehicles without trailers.
•Never try to stop a trailer from snaking by increasing your speed.
•Never install a weight-distributing or load-balancing towing bracket on the vehicle.
WARNING
The start/stop system must always be switched off manually when towing a trailer using
towing brackets that have not been retrofitted by Volkswagen. Otherwise faults can occur
in the brake system, possibly resulting in accidents and serious injuries.

Meaning of indicator lamp in the button
•If the indicator lamp in the button ⇒ Fig. 192 is lit up permanently when the boot lid is open, the
ball head is correctly engaged in the extended or retracted position.
•If the indicator lamp in the button flashes, the ball head has either not clicked into place properly
or it is damaged ⇒.
•The indicator lamp in the button goes out approximately one minute after the luggage
compartment is closed.
Improper use of the towing bracket can cause injury and accidents.
•Only use the ball head if it has clicked into place properly.
•Ensure that no people, animals or items are in the path of the ball head.
•Never interrupt the ball head, for example with tools, when it is swivelling.
•Never press the button ⇒ Fig. 192 if a trailer is attached or if a luggage rack or other
accessories are fitted to the ball head.
•If the ball coupling does not engage properly or there is a fault in the electrical system
or the towing bracket itself, do not use the towing bracket and have it checked by an
authorised workshop.
•Never use the towing bracket if the diameter of the ball is below 49 mm at the smallest
point.
WARNING
Do not aim a high-pressure cleaner or steam cleaner directly at the mechanically
positioned ball coupling or the fitted trailer socket. Seals could be damaged or the grease
required for lubrication could be washed off.
NOTICE

At extremely low outside temperatures, the electric ball head might not rotate. If this
happens, it is sufficient to place the vehicle in a warmer room, e.g. a garage.
Fitting a bicycle carrier on the swivelling ball head
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Mount the bicycle carrier in accordance with the manufacturer's assembly instructions.
Only carrier systems which can hold a maximum of three bicycles may be used ⇒. Position
heavy bicycles as close to the vehicle (ball headyfDVSRVVLEOH.
Maximum carrying load
The maximum permitted load (carrier system including loadyfRQWKHEDOOFRXSOLQJLV 75 kg at a
distance of 300 mm. This distance refers to the gap between the centre of gravity of the bicycle
carrier and the middle of the ball head.
Volkswagen recommends that you remove all add-on parts from the bicycles before setting
off. This includes for example bicycle bags and baskets, child seats or batteries. This helps improve
the carrier system's wind load and centre of gravity.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
Headlight adjustment
Towing a trailer can raise the front end of the vehicle enough for the dipped beam to blind other
road users. Use the headlight range control to lower the light cone as required. Vehicles with
automatic headlight range adjustment are adjusted automatically.
Things to note when driving with a trailer
•If the trailer has an overrun brake, apply the brakes gently at first and then firmly. This will
prevent the jerking that can be caused by the trailer wheels locking.
•The combination weight causes the braking distance to increase.
•Engage a lower gear prior to inclines (manual gearbox or Tiptronic mode of the automatic
gearboxyfWRDGGLWLRQDOO\PDNHXVHRIHQJLQHEUDNLQJ7KHEUDNHV\VWHPFRXOGRWKHUZLVH
overheat and fail.
•The vehicle's centre of gravity and, in turn, the vehicle's handling, will change because of the
trailer load and the increased combined towing weight of the vehicle and trailer.
•The weight distribution of a loaded trailer with an unladen towing vehicle is very unfavourable.
When driving in this situation, drive particularly carefully and slowly.
Pulling off on slopes when towing a trailer
A vehicle towing a trailer is liable to roll back a short distance when moving off on a slope,
depending on the angle of the slope and the total weight of the trailer and vehicle.
When towing a trailer, pull off on slopes as follows:
•Depress and hold the brake pedal.
•Press button once to switch off the electronic parking brake ⇒ Electronic parking 
brake.
•Manual gearbox: depress the clutch fully.
•Select first gear ⇒ Manual gearbox: selecting a gear or selector lever position D/S⇒ DSG dual 
clutch gearbox.
•Pull on the button and hold it in this position to hold the vehicle and trailer with the
electronic parking brake.
•Release the brake pedal.
•Pull away slowly. To do this, slowly release the clutch pedal for a manual gearbox.
•Only let go of the button when the engine has sufficient power to move off.
Trailer stabilisation

necessary at a qualified workshop.
Checklist Information on changing bulbs
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
Always carry out the following actions for changing a bulb in the given order ⇒:
Accidents can occur if roads are not sufficiently illuminated and other road users have
difficulty seeing the vehicle, or cannot see it at all.
WARNING
Changing the bulb incorrectly can cause accidents and serious injuries.
•When working in the engine compartment, always read and observe the safety
warnings ⇒ In the engine compartment. The engine compartment of any motor vehicle
is a dangerous area. Serious injuries can be sustained here.
•H7/H15 bulbs are pressurised and could explode when they are being changed.
•Only change the defective bulb once it has had time to cool down completely.
•Never change a bulb unless you are familiar with the procedure. If you are uncertain of
what to do, the work should be carried out by a qualified workshop.
•Do not touch the glass part of the bulb with unprotected fingers. When the light is
switched on, heat will cause fingerprints to evaporate on the bulb, which in turn will
cause the reflector to dim.
•There are sharp-edged parts in the headlight housing in the engine compartment and
on the tail light cluster housing. Protect your hands when changing bulbs.
WARNING
Damage to the electrical system can be caused by water entering the system if the rubber
covers or plastic caps on the headlight housing are not properly mounted after a bulb has
been changed.
