2021 VOLKSWAGEN T-ROC ECU

Before driving through an automatic car wash.
The vehicle height exceeds the required clearance height, e.g. in a garage.

NOTICE
Always remove the roof carrier before driving through an automatic car wash.
The height of the vehicle is changed by the installation of a roof carrier and the load secured to it.
Check and compare the height of the vehicle with clearance heights, e.g. for underpasses and garage
doors.
The roof carrier and its load must not obstruct you from opening and closing the glass roof and the
boot lid. The roof aerial must also remain unaffected.

Driving with a fitted roof carrier will increase air resistance and thus increase fuel consumption.
Trailer towing
Introduction
This chapter contains information on the followingsubjects:
⇒ Technical requirements 
⇒ Fitting the removable ball head 
⇒ Removing the ball head 
⇒ Notes on towing a trailer 
⇒ Loading the trailer 
⇒ Driving with a trailer 
⇒ Trailer stabilisation 
⇒ Retrofitting a towing bracket 
The vehicle can be used to tow a trailer if it has the required technical equipment for this. The
additional trailer load will affect the amount of wear, fuel consumption and performance of the
vehicle and, in certain circumstances, could shorten the service intervals.
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
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 towing a trailer, and it must
remain deactivated for as long as a trailer is being towed ⇒ .

DANGER
It is dangerous to transport people in a trailer and it may also be illegal.

WARNING
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
designed 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 and increase
the braking distance. This can lead to accidents.
Always secure loads properly using suitable and undamaged lashing, retaining or 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 very 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 mph) when towing a trailer, also 100 km/h (60 mph) 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.

Turn the key ⑦ clockwise until the part of the lock with the holes is at the top.
Fit the lock cap ⑧ on the lock and place the key ⑦ in the vehicle toolkit.
Step 5: safety check
Before hitching a trailer, check if the ball head is fixed correctly.
The locking lever ⇒ Fig. 155  ⑥ is in the uppermost position.
The green section of the release pin ⑨ is visible.
Shake the ball head ② or pull it down with some force. It must sit firmly in the mounting ⇒ .
The lock must be locked and the key ⑦ removed.
The lock cover ⑧ must cover the lock in the locking lever.

WARNING
Improper use of the towing bracket can cause injuries and accidents.

Tyre pressure
Follow the trailer manufacturer's recommendations concerning the tyre pressure for the trailer
tyres.
When towing a trailer, inflate the wheels on the towing vehicle with the maximum permitted tyre
pressure ⇒ Tyre pressure .

WARNING
Accidents and serious injuries can occur if you exceed the vehicle's maximum permitted gross axle
weight rating, drawbar load, gross vehicle weight rating or gross combination weight rating.

vehicle.

WARNING
Loads that may slide can severely impair stability and driving safety, which can cause accidents and
severe injuries.

Driving with a trailer
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 dazzle other
road users. Use the headlight range control to lower the light cone as required. Vehicles with
dynamic headlight range control 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.

In vehicles that are factory-fitted with a spare wheel, emergency spare wheel or winter wheels,
additional vehicle tools may be located in the luggage compartment.

WARNING
In the event of a sudden driving or braking manoeuvre or accident, a loose vehicle toolkit,
breakdown set and spare wheel or temporary spare wheel could be flung though the vehicle and
cause severe injuries.

Changing bulbs in the tail light clusters (LED lights)
First read and observe the introductoryinformation and safety warnings⇒Introduction 
These lamps use LED technology. The LEDs cannot be replaced by customers. If some LEDs fail, this
may be an indication that more elements are on the point of failure. In this case, have the lights
checked and renewed if necessary at a qualified workshop. Volkswagen recommends using a
Volkswagen dealership for this purpose.

Suitable earth connection: preferably the jump lead connection point (earth connection), a
solid metal part which is securely bolted onto the cylinder block, or the cylinder block itself.
The discharged 12-volt vehicle battery must be properly connected to the vehicle's electrical system.
The vehicles must not touch. Otherwise electricity could flow as soon as the positive terminals are
connected.
Ensure that the battery clamps have good metal-to-metal contact with the battery terminals.
If the engine does not start immediately, switch off the starter after about 10 seconds and try again
after about a minute.
If the engine still does not start, seek expert assistance.
Attaching the jump leads
The jump leads should be connected only in the order A – B – C – D⇒ Fig. 177 .
The black jump lead should never be connected to the negative terminal (–) on the 12-volt vehicle
battery. Connecting the lead to the negative terminal can cause incorrect condition evaluation of the
12-volt vehicle battery in the vehicle electronics.
