Number of seats
The vehicle has a total of five seats: two seats at the front and three seats at the rear. Each seat is
equipped with a seat belt.
Dangers of assuming an incorrect sitting position
First read and observe the introductoryinformation and safety warnings⇒
Introduction
If the seat belts are not worn or are worn incorrectly, the risk of severe or fatal injuries increases.
Seat belts can only provide optimal protection if the seat belt routing is correct. Assuming an
incorrect sitting position considerably impairs the level of protection provided by a seat belt. This
could lead to severe or even fatal injuries. The risk of severe or fatal injuries is especially increased
when a deploying airbag strikes a vehicle occupant who has assumed an incorrect sitting position.
The driver is responsible for all occupants transported in the vehicle, especially children.
The following list contains examples of sitting positions that can be dangerous for all vehicle
occupants.
Whenever the vehicle is in motion:
•Never stand in the vehicle.
•Never stand on the seats.
•Never kneel on the seats.
•Never tilt the backrest too far to the rear.
•Never lean against the dash panel.
•Never lie on the rear bench seat.
•Never sit on the front edge of a seat.
•Never sit sideways.
•Never lean out of a window.
•Never put your feet out of a window.
•Never put your feet on the dash panel.
•Never place your feet on the seat cushion or seat backrest.
•Never travel in a footwell.
•Never sit on the armrests.
•Never travel on a seat without wearing the seat belt.
•Never travel in the luggage compartment.
Correct sitting position
Assuming an incorrect sitting position in the vehicle can increase the risk of severe or
fatal injuries during a sudden driving or braking manoeuvre, in the event of a collision or
accident, or if the airbags are triggered.
•All vehicle occupants must assume a correct sitting position before setting off and
maintain this position throughout the trip. This also applies to the fastening of seat
belts.
•The number of vehicle occupants must never exceed the number of seats with seat
belts in the vehicle.
•Always secure children in the vehicle in an authorised restraint system which is
suitable for their height and weight ⇒ Safe transport of children and ⇒ Airbag system.
•Always keep your feet in the footwell while the vehicle is in motion. Never place your
feet on the seat or dash panel, for example, and never ride with your feet out the
window. When you are sat like this, the airbag and seat belt cannot provide optimal
protection and could actually increase the risk of injury during an accident.
WARNING
Every incorrect sitting position in the vehicle increases the risk of severe or fatal injuries
in the event of an accident or sudden driving or braking manoeuvre.
•All vehicle occupants must maintain a correct sitting position and wear their seat belt
properly while the vehicle is in motion.
•Sitting in an incorrect position, not fastening the seat belt, or not leaving adequate
space between the occupants and the airbags could result in critical or fatal injuries,
especially if the airbags deploy and strike an occupant who has assumed an incorrect
sitting position.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
The following details the correct sitting positions for the driver and passengers.
If any vehicle occupants cannot assume a correct sitting position due to their physical build, they
should contact a qualified workshop to find out about possible special modifications. The seat belts
and airbags can only provide a maximum level of protection if a correct sitting position is assumed.
Volkswagen recommends using a Volkswagen dealership for this purpose.
Volkswagen recommends the following seating position for your own safety and to reduce the level
of injury in the event of a sudden braking manoeuvre or an accident:
The following applies to all vehicle occupants:
•Adjust the head restraint so that its upper edge is at the same height as the top of the head, but
not lower than eye level. Position the back of your head as close to the head restraint as
possible ⇒ Fig. 30.
•For small people, push the head restraint all the way down, even if the head is then located
underneath the top edge of the head restraint.
•For taller people, push the head restraint up as far as it will go.
•Keep both feet in the footwell while the vehicle is in motion.
•Adjust and fasten seat belts properly ⇒ Seat belts.
Additional points for the driver:
•In vehicles with head restraints that can be moved backwards and forwards, position the head
restraint as close as possible to the back of your head.
•Move the backrest into an upright position so that your back rests fully against it.
•Adjust the steering wheel so that the distance between the steering wheel and your breastbone
is at least 25 cm ⇒ Fig. 30Ⓐ, and the circumference of the steering wheel can be held at the
sides with both hands and your arms slightly bent ⇒ Steering wheel.
•The steering wheel must always point towards the breastbone and not towards the face.
•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 ⇒ Fig. 30Ⓑ.
•Adjust the height so that you can reach the highest point of the steering wheel.
•Always leave both feet in the footwell, to help ensure you maintain control of the vehicle at all
times.
Additional points for the front passenger:
•In vehicles with head restraints that can be moved backwards and forwards, position the head
restraint as close as possible to the back of your head.
•Move the backrest into an upright position so that your back rests fully against it.
•Push the front passenger seat as far back as possible so that the airbag can provide maximum
protection if it is deployed.

the seat to the highest position. Adjust the backrest to an upright position ⇒ Sitting position.
•When using child seats from groups 0 or 1 on the rear bench seat, push the rear bench seat
backwards as far as possible ⇒ Sitting position.
•When using child seats from groups 2 or 3 on the rear bench seat, push the rear bench seat
into a central position ⇒ Sitting position.
•Always ensure that there is enough space around the child seat. If necessary, adjust the
position of the seat in front. When doing so, ensure that the driver or front passenger can still
maintain a correct sitting position ⇒ Sitting position.
•The backrest of the child seat must lay as flat as possible against the vehicle seat backrest.
Adjust the seat backrest angle if necessary so that the child seat lies flush against the backrest.
If the child seat, once fitted, touches the vehicle head restraint so that it cannot lie flat against
the backrest, push the vehicle head restraint up as far as it will go or remove it and stow it away
safely in the vehicle ⇒ Sitting position.
Airbag sticker
The vehicle may be provided with stickers giving key information about the front passenger front
airbag. The information on these stickers may vary from country to country. The stickers may be
found:
•On the driver and/or front passenger sun visor ⇒ Fig. 53.
•On the B-pillar on the passenger side ⇒ Fig. 54.
It is essential to note the warning information shown on these stickers before installing a rear-facing
child seat ⇒.
Risks involved in carrying children on the front passenger seat
If you are using a rear-facing child seat, the front passenger front airbag can cause critical or
potentially fatal injuries when it inflates ⇒.
Rear-facing child seat may only be used on the front passenger seat if the front passenger front
airbag has been deactivated. A deactivated front passenger front airbag is indicated by means of
the permanently lit PASSENGER AIR BAG indicator lamp in the driver's field of vision.
Switching off the front passenger front airbag ⇒ Airbag system, PASSENGER AIR BAG
indicator lamp ⇒ Indicator lamp.
If using a front-facing child seat, do not deactivate the front passenger front airbag. When fitting
the child seat ensure ensure that it is as far away as possible from the front passenger front airbag.
The front passenger front airbag can cause severe injuries when it inflates ⇒.
Some child seats are not suitable for use on the front passenger seat. The child seat must be
specially authorised by the manufacturer for use on the front passenger seat in vehicles with front
and side airbags. Volkswagen dealerships keep an up-to-date list of authorised child seats.
If you use a rear-facing child seat on the front passenger seat, the child in it is at
increased risk of sustaining critical or fatal injuries in the event of an accident.
•Deactivate the front passenger front airbag. If the front passenger front airbag cannot
be deactivated no rear-facing child seat may be used.
•Move the front passenger seat as far back and as high as possible in order to create
the largest possible distance between the child seat and the front passenger front
airbag.
•Move the backrest to the upright position.
•Move the seat belt height adjuster 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.
DANGER
Child seats present a risk of injury if incorrectly installed.
•Always read and follow the installation instructions and warning information provided
by the child seat manufacturer.
WARNING
Page 89 of 341

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.

Eco driving profile ⇒ Driving profile selection and 4MOTION Active Control.
Avoid full throttle
Never fully use the maximum speed of the vehicle. Driving at excessive speeds, e.g. above 130
km/h on the motorway, will increase air resistance and thus the amount of force needed to move
the vehicle.
Reduce idling
Drive off immediately with low revs. If you are stopped for a long period, do not allow the engine to
idle but switch it off, e.g. when in a traffic jam or at a railway crossing.
In vehicles with an activated start/stop system, the engine will switch off automatically when the
vehicle is stopping and when the vehicle is stationary ⇒ Start/stop system .
Refuel with moderation
A full fuel tank increases the weight of the vehicle. A fuel tank that is half to three quarters full is
sufficient for urban journeys in particular.
Avoid short journeys
A cold engine has a very high fuel consumption. The optimum operating temperature is reached
only after driving a few miles. The fuel consumption is above average at very low ambient
temperatures, e.g. in winter ⇒ Fig. 116. Plan journeys economically and combine short distances.
Carry out regular maintenance
Regular maintenance is an essential prerequisite for economical driving and increases the service
life of the vehicle.
Observe the correct tyre pressures
An inadequate tyre pressure does not just mean greater wear, but also increases the rolling
resistance of the tyres and thus the fuel consumption. Use optimised rolling resistance tyres.
Adjust the tyre pressure according to the vehicle load. Observe the information on the tyre pressure
sticker ⇒ Useful information about wheels and tyres
Tyre Pressure Loss Indicator or Tyre Pressure Monitoring System ⇒ Tyre monitoring systems.
Use low viscosity engine oil
Fully synthetic engine oils with a low viscosity decrease frictional resistance in the engine and
spread better and more quickly, especially for cold starts.
Do not drive with unnecessary loads in the vehicle
You can reduce fuel consumption by clearing out the luggage compartment before setting off, for
example by removing empty drink crates or unused child seats.
In order to keep the drag coefficient of the vehicle as low as possible, remove attachments and
add-on parts such as ski, bicycle or roof carriers after use.
Save electrical energy
The alternator is driven by the engine and generates power for convenience consumers such as the
air conditioning system, window heating and ventilation. Saving electrical energy is easy, e.g.:
•At high ambient temperatures, ventilate the car before starting a journey and drive a short
distance with open window. Only then switch on the air conditioning system.
•Switch off convenience systems as soon as they have served their purpose.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road
and traffic conditions.

DSG dual clutch gearbox
Function of the DSG dual clutch gearbox
Description
The vehicle is equipped with a DSG dual clutch gearbox.
The DSG dual clutch gearbox is a gearbox which uses dual-clutch technology to change gear
automatically. It uses a dual clutch and two gear train halves to enable very fast gear changes with
no loss of torque. The DSG dual clutch gearbox thus combines the performance and economy of a
manual gearbox with the comfort and convenience of a conventional automatic transmission.
Function
When driving, engine power is transferred to the drive axle via the gearbox. In order to change
gears, the power transmission between the engine and the gearbox has to be interrupted. This is
what the clutch is for.
With the DSG dual clutch system with its two gear train halves, the engine power is always
connected to one gear train half when driving. Before a gear change, the next higher or lower gear
is already preselected in the load-free second gear train half. The clutch on the non-driven gear is
closed and the other is opened at the same time. This is what makes very fast gear changes
possible.
Thanks to its design, the DSG dual clutch gearbox is more efficient than an automatic gearbox.
Whereas in an automatic gearbox the torque converter is constantly in use, in the DSG dual clutch
system the clutch can be opened at idling speed, thus saving fuel. Thanks to its efficiency, low
weight and intelligent control system, the DSG dual clutch system usually enables fuel
consumption equal to or lower than a manual gearbox.
However, just like the manual gearbox, the clutch in the DSG dual clutch gearbox is subject to
wear. Regular maintenance is necessary depending on the type of dual clutch gearbox DSG;
further information ⇒ Scope of service. In the event of a fault in one gear train half, the DSG dual
clutch gearbox also allows one gear train half to be deactivated and the journey to be continued
using the other gear train half ⇒ Troubleshooting. If this happens, have the system checked as
soon as possible by a qualified workshop.

Serious damage to the clutch and gearbox can occur if the gear stick on the manual
gearbox is shifted to too low a gear when travelling at high speeds or at high revs. This
also applies if the clutch remains depressed and the gears do not engage.
NOTICE
Please note the following to help avoid damage and premature wear:
•Do not rest your hand on the gear lever when driving. The pressure from your hand is
passed onto the selector forks in the gearbox.
•Ensure that the vehicle has come to a full stop before engaging reverse gear.
•Always fully depress the clutch pedal when changing gear.
•Do not hold the vehicle by riding the clutch on a hill with the engine running.
