ECU VOLKSWAGEN TIGUAN 2020 User Guide

•Weight class 0/0+: group 0/0+ or 0/1 rear-facing infant carriers ⇒ Fig. 52 are the best option
for the period from birth to about 18 months.
•Weight class 1: group 1 (up to about four years oldyfRUJURXSXSWRDERXWVHYHQ\HDUVROG\f
with an integral belt system are best for children over the relevant weight limit.
•Weight classes 2/3: groups 2 and 3 include child seats with a backrest, and booster seats with
no backrest. Child seats with a backrest have integrated seat routing and side cushions, and so
provide better protection than booster seats with no backrest. Volkswagen therefore
recommends the use of child seats with a backrest. Group 2 child seats are for children up to
the age of about seven, group 3 child seats for those older than seven.
Not every child will fit in the child seat specified for their weight group. Likewise, not every seat will
fit in every vehicle. Therefore it is vital to check that the child fits properly in their child seat and that
the child seat can be securely fastened in the vehicle.
Child seat approval categories
Child seats can be classified as universal, semi-universal or vehicle-specific (all in accordance with
regulation ECE-R 44yfRUDVL6L]HLQDFFRUGDQFHZLWKUHJXODWLRQ(&(5\f.
•Universal: child seats with universal approval are approved for use in all vehicles. No type list
is required. ISOFIX child seats with universal approval must also be securing using a strap over
the top of the vehicle seat (top tetheryf.
•Semi-universal: semi-universal approval requires other safety devices for attaching the seat
(that require additional testingyfLQDGGLWLRQWRWKHVWDQGDUGUHTXLUHPHQWVIRUXQLYHUVDODSSURYDO
Child seats with semi-universal approval come with a type list. The seats should only be used in
vehicles that are included on this list.
•Vehicle-specific: child seats with vehicle specific approval must have undergone dynamic
testing in each model of vehicle for which it is approved. These child seats also come with a
type list.
•i-Size: child seats classified as i-Size must conform to the installation and safety requirements
prescribed in regulation ECE-R 129. Contact the child seat manufacturer to find out which child
seats are approved for this vehicle in accordance with i-Size.
Regulation ECE-R 129 has not yet been implemented by the state authorities in all countries.

Introduction
Country-specific regulations
The standards and regulations governing the use of child seats and child seat securing
mechanisms differ from country to country. Not all countries allow you to transport children on the
front passenger seat. Legislation and legal requirements take precedence over the information
given in this owner's manual.
Information on fitting a child seat
Observe the following general information when fitting a child seat. This information is relevant
whatever child seat securing system is being used.
•Read and follow the instructions provided by the child seat manufacturer ⇒.
•Whenever possible, fit all child seats to the rear seat behind the front passenger seat so that
children can exit the vehicle on the kerb side.
•Move the seat belt height adjuster to the highest position.

Securing systems
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Different countries use different securing systems for safely fitting child seats in the vehicle.
Key terms for securing systems
•ISOFIX: ISOFIX is a standardised securing system for fitting child seats in the vehicle quickly
and safely. The ISOFIX attachment system creates a rigid connection between the child seat
and the car body.
Compatible child seats have two rigid attachment arms that click into ISOFIX attachment points at
the bottom of the backrest (on the outer rear seatsyf7KH,62),;VHFXULQJV\VWHPDVGHVFULEHG
here is specific to Europe ⇒ Securing child seats with ISOFIX. An upper strap (top tetheryfDQGRU
support foot may sometimes have to be used in addition to the ISOFIX anchor points described
above.
•Three-point automatic seat belt. It is better to secure child seats using the ISOFIX system, if
available, rather than with a three-point automatic seat belt ⇒ Securing child seats with a seat 
belt.
Additional securing points:
•Top tether: the strap at the top of the child seat is routed over the vehicle seat backrest and
hooked to an anchor ring on the back of the rear seats ⇒ Securing child seats with top tether 
upper strap. Top tether anchor points are marked with an anchor symbol.
•Support foot: some child seats are propped up with a support foot resting on the floor of the
vehicle. This support foot helps prevent the child seat tipping forward in a crash. Child seats
with a support foot can be used only on the front passenger seat and the outer rear seats ⇒.
Recommended child seat securing systems
Volkswagen recommends that child seats are secured as follows:
•Infant carrier or rear-facing child seat: ISOFIX and support foot.
•Front-facing child seat: ISOFIX and top tether and possibly support foot also.
Securing child seats with ISOFIX
Fig. 55 On vehicle seat: markings identifying the ISOFIX anchoring points for child seats.
Using a front-facing child seat on the front passenger seat presents a risk of injury.
•Move the front passenger seat as far back and as high as it can be set, to create the
largest possible distance between the child seat and the front passenger front airbag.
•Move the backrest to the upright position.
•Set the belt height adjuster of the seat belt to the highest position.
•Use only child seats that have been approved by the child seat manufacturer for use on
a front passenger seat with front and side airbags.
WARNING
To help avoid injuries caused by inflation of a head airbag or side airbag:
•Ensure that no children are seated within the airbag deployment zone ⇒ Airbag 
system.
•Do not place any objects in the side airbag deployment zones.
WARNING
Incorrect use of the support foot can cause severe or fatal injuries.
•Ensure that the support foot is always correctly and safely installed.

Boot lid
Introduction
This chapter contains information on the followingsubjects:
⇒ Opening and closing the boot lid
⇒ Electrically opening and closing the boot lid
⇒ Boot lid with movement sensor (yf
⇒ Automatically closing the boot lid (yf
⇒ Unlocking the boot lid manually
⇒ Troubleshooting
The boot lid is unlocked and locked together with the doors.
On vehicles with the keyless locking and starting system Keyless Access, the boot lid is unlocked
automatically when it is opened ⇒ Locking and unlocking the vehicle with keyless access.
Incorrect and unsupervised unlocking, opening or closing of the boot lid can cause
accidents and serious injuries.
•The boot lid should only be opened or closed when you are sure that nobody is in its
path.
•Always check that the boot lid is properly closed after closing it. The closed boot lid
must be flush with the surrounding body panels.
•Always keep the boot lid closed while the vehicle is in motion.
•Never open the boot lid when loads, e.g. bicycles, are attached to it. The boot lid may
close under its own weight due to the additional load. Support the boot lid as
necessary or remove the load before opening.
•Close and lock the boot lid and all vehicle doors when the vehicle is not in use. Ensure
that no one remains in the vehicle.
•Never leave children playing unattended in or around the vehicle, especially when the
boot lid is open. Children could climb into the luggage compartment and shut the boot
lid, thereby trapping themselves inside. Temperatures inside a locked vehicle may
reach extremes of heat or cold, according to season. This can cause serious injuries
and illness or fatalities, especially to small children.
WARNING
Serious injuries could occur if the boot lid is unlocked or opened incorrectly or without
due care and attention.
•The boot lid may not always be detected as being unlocked if there is a carrier and
items attached to it. The boot lid may open suddenly while the vehicle is in motion if it
is unlocked.
WARNING
If there is a large amount of snow or a heavy load on the boot lid, the boot lid may lower
by itself and cause serious injuries due to the additional weight.
•Never open the boot lid if it is covered by a large amount of snow or a load is attached
to it, e.g. a rack or luggage carrier.
•Remove the snow or luggage before opening the boot lid.
WARNING

Seats and head restraints
Front seats
Introduction
This chapter contains information on the followingsubjects:
⇒ Mechanically adjusting the front seat
⇒ Electrically adjusting the front seat
⇒ Folding the front passenger seat backrest forwards
The following section describes the options for adjusting the front seats. Always ensure that the
correct sitting position is adjusted ⇒ Sitting position.
Incorrect use of the steering column position adjustment and incorrect adjustment of the
steering wheel can cause serious or fatal injuries.
•After adjusting the steering column, always move lever ⇒ Fig. 77① up so that it
engages securely. This prevents the steering column from moving spontaneously
while the vehicle is in motion.
•Never adjust the steering wheel when the vehicle is in motion. If you determine that a
readjustment is necessary, stop the vehicle safely and adjust the steering wheel to the
correct position.
•The steering wheel must always point towards the chest and not towards the face. This
ensures that the driver front airbag provides maximum protection in the event of an
accident.
•While driving, always keep both hands on the outside of the steering wheel at the 9 
o'clock and 3 o'clock positions⇒ Fig. 78. This reduces the risk of injury if the driver
front airbag is triggered.
•Never hold the steering wheel at the 12 o'clock position, or in any other manner, e.g. on
the hub of the steering wheel. If the driver front airbag is triggered, you could receive
severe injuries to the arms, hands and head.
WARNING

Mechanically adjusting the front seat
Always adjust the front seats to their correct position before any journey and ensure that
any passenger has fastened their seat belt.
•Push the front passenger seat as far back as possible.
•Adjust the driver seat so that there is at least 25 cm between your breastbone and the
hub of the steering wheel. Adjust the driver seat by moving it forwards or backwards
so that you are able to press the pedals to the floor with your knees still slightly bent
and so that the distance from the dash panel to your knees is at least 10 cm. If your
build makes it impossible to fulfil this requirement then you must contact a qualified
workshop so they can make any necessary modifications.
•Never travel with the backrest tilted far back. The further back the backrest is tilted, the
greater the risk of injury caused by incorrect seat belt routing or an incorrect sitting
position.
•Never travel with the backrest tilted far forwards. When a front airbag is triggered it
could force the seat backrest backwards and injure vehicle occupants on the back
seats.
•Adopt and maintain the greatest possible distance from the steering wheel and dash
panel.
•You should always sit upright with your back against the seat backrest with the front
seats properly adjusted. Do not position any body part too close where the airbags are
fitted.
•The risk of serious injury is increased for passengers on the rear seat if they are not
sitting upright because the seat belts are incorrectly positioned.
WARNING
Incorrect adjustment of the seats can cause accidents and serious injuries.
•Only adjust the seats when the vehicle is stationary. The seats could change position
unexpectedly if you attempt to reposition them while the vehicle is in motion, leading
to a loss of control of the vehicle. Furthermore, an incorrect seating position is
adopted while adjusting the seat.
•Only adjust the height and tilt of the seat or move it forwards and backwards when the
area around the seat is clear.
•To be able to make adjustments to the seats, the area around them must not be
restricted by any items.
•Only adjust the height of the rear seat or move it forwards and backwards when the
area around the seat is clear.
•The areas for adjusting and locking the seats must not be soiled.
WARNING
Improper use of seat covers or protective covers may lead to the electrical seat controls
being operated accidentally and the front seats moving unexpectedly while the vehicle is
moving. You could lose control over the vehicle. This could result in serious injury and
accidents. Furthermore, this may result in damage to the electrical components in the
front seats.
•Never attach or secure seat covers or protective covers to the electrical controls.
•Do not fit seat covers or protective covers over the seats unless they have been
expressly approved for use in the vehicle.
WARNING
Cigarette lighters in the vehicle could be damaged or accidentally lit. This could lead to
serious burns and other injuries.
•Before adjusting the seats always ensure that there is no lighter on or near the
moveable parts of the seat.
•Before closing stowage areas or compartments always ensure that there is no lighter
in the way.
•Never stow lighters in stowage areas, compartments or on other surfaces in the
vehicle. High surface temperatures, especially in summer, may cause cigarette lighters
to self-ignite.
WARNING
