2021 VOLKSWAGEN TIGUAN engine

If there is a fault in the vehicle or trailer electrical systems or in the anti-theft alarm or if there
is a fault in the anti-theft alarm, have the vehicle checked by a qualified workshop.
If the engine is not running and electrical equipment is switched on in the trailer via the trailer
socket, the 12-volt vehicle battery will discharge.
If the 12-volt vehicle battery charge level is low, the electrical connection to the trailer will be
interrupted automatically.
Loading the trailer
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Trailer weight and drawbar load
The trailer weight is the weight that the vehicle can pull ⇒. The drawbar load is the load that is
exerted vertically from above onto the ball head of the towing bracket ⇒ Information on technical 
data.
The figures for trailer weights and draw bar weights that are given on the data plate of the towing
bracket are for certification purposes only. The correct values for your specific model, which may be
lower than these figures, are given in the vehicle registration documents. All data in the official
vehicle documents take precedence over these data.
The maximum permitted drawbar load exerted by the trailer drawbar on the ball head of the towing
bracket must not exceed 100 kg.
In the interest of driving safety, Volkswagen recommends that you always use the maximum
drawbar load. The response of the trailer on the road will be poor if the drawbar load is too small.
The drawbar load increases the weight on the rear axle and reduces the maximum load level as a
result.
Gross combination weight rating
The combination weight is made up of the actual weight of the loaded vehicle and of the loaded
trailer.
In some countries, trailers are divided into different classes. Volkswagen recommends that you
contact a qualified workshop to find out about suitable trailers.
Loading the trailer
The weight of the load should be distributed evenly. The maximum permitted drawbar load should
be utilised. Do not place the load only at the front or the rear of the trailer:
•Distribute the load in the trailer so that heavy objects are either over or as near to the axle as
possible.
•Secure all loads on the trailer properly.
Tyre pressure
Follow the trailer manufacturer's recommendations concerning the tyre pressure for the trailer tyres.
When towing a trailer, inflate the tyres on the towing vehicle with the maximum permitted tyre
pressure ⇒ Tyre pressure.
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.
•Never exceed the specified values.
•Never let the actual weights at the front and rear axles exceed the gross axle weight
ratings. Never exceed the permissible gross vehicle weight for the vehicle with weight
at the front and rear of the vehicle.
WARNING
Loads that may slide can severely impair stability and driving safety, which can cause
accidents and severe injuries.
•Always load trailers correctly.
•Always secure loads properly using suitable and undamaged securing straps.
WARNING

Trailer towing
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
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The trailer stabilisation function can detect if an attached trailer is starting to lurch from side to side
and can provide countersteer.
Trailer stabilisation is a subsidiary function of the Electronic Stability Control (ESCyf.
®
Incorrect trailer towing can cause loss of vehicle control and serious personal injury.
•Towing a trailer and transporting heavy or bulky items can change the way the vehicle
handles and increase the braking distance.
•Always drive carefully and think ahead. Brake earlier than in normal driving.
•Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions. Reduce your speed, particularly when going downhill.
•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 try to stop a trailer from snaking by increasing your speed.
•Keep to speed limits which may be lower for vehicles with trailers than for vehicles
without trailers.
