Driving notes when towing
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Towing requires some experience, especially when using a tow rope. Both drivers should be
familiar with the technique required for towing. Inexperienced drivers should not attempt to tow.
When driving, remember not to pull too hard on the towing vehicle and take care to avoid jerking
movements. When towing on an unpaved road, there is always a risk of overloading and damaging
the anchorage points.
It is still possible to activate the turn signals in a vehicle that is being towed, even if the hazard
warning lights are switched on. To do this, operate the turn signal lever in the required direction
while the ignition is switched on. The hazard warning lights will not flash while the turn signal is
being used. The hazard warning lights will start flashing automatically as soon as the turn signal
lever is moved back to the neutral position.
Notes for the driver of the towed vehicle:
•Leave the ignition of the vehicle being towed switched on to prevent the steering wheel from
locking, to enable the electronic parking brake to be switched off, and to ensure that the turn
signals, wipers and washer system can be used.
•As the power assisted steering does not work if the engine is not running, you will need more
strength to steer than you normally would.
•You will need to depress the brake pedal more vigorously than normal as the brake servo is not
working. Do not drive too close to the towing vehicle.
•Read and comply with the information and notes in the owner's manual of the towing vehicle.
Notes for the driver of the towing vehicle:
•Accelerate carefully and gently. Avoid any sudden driving manoeuvres.
•Brake earlier than normal by pressing lightly on the brake pedal.
•Read and comply with any information and notes in the owner's manual of the towed vehicle.
Checking and refilling
In the engine compartment
The towing eye must always be screwed firmly into the mounting. Otherwise, the towing
eye can be ripped out of the mounting when the vehicle is being tow-started or towed.
NOTICE

Safety notes for working in the engine compartment
Always park the vehicle on a level and stable surface before carrying out any work in the engine
compartment.
The engine compartment of a motor vehicle is a hazardous area. You should only carry out work on
the engine, and in the engine compartment, if you know exactly how to perform the required tasks,
are aware of the general safety procedures and have access to the correct equipment, service
fluids and suitable tools. Failing to carry out work correctly can cause serious injuries ⇒. The
work should be carried out by a qualified workshop if you are uncertain. Volkswagen recommends
using a Volkswagen dealership for this purpose.
Unintentional vehicle movements during service work can cause serious injury.
•Never work underneath a vehicle if it is not secured against rolling away. If you are
working underneath the vehicle while the wheels are on the ground, the vehicle must
be on a level, the wheels chocked, and the vehicle key removed from the ignition lock
as required.
•If you have to work underneath the vehicle, use suitable stands to provide extra
support for the vehicle. The vehicle jack is not sufficient for this task and can fail,
which can lead to serious injuries.
•The start/stop system must have been deactivated.
WARNING
The engine compartment of any motor vehicle is a dangerous area. Serious injuries can be
sustained here.
•The utmost care and attention must be paid when carrying out any work and you must
follow the general safety rules. Never take any risks.
•Never do any work on the engine or in the engine compartment unless you know
exactly how to carry it out. If you are uncertain of what to do, the work should be
carried out by a qualified workshop. Serious injuries can result from work that has not
been carried out properly.
•Never open the bonnet if you see steam or coolant escaping from the engine
compartment. Hot steam or hot coolant can cause serious burns. Always wait until you
can no longer see or hear steam or coolant coming from the engine compartment.
•Always allow the engine to cool down before opening the bonnet.
•Hot parts of the engine or exhaust system can burn the skin.
•Observe the following points before opening the bonnet once the engine has cooled
down:
- Switch on the electronic parking brake and move the selector lever to position P
or move the gear lever to the neutral position.
- Switch off the ignition and remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.
•The cooling system is under pressure when the engine is hot. Never open the cap of
the coolant expansion tank when the engine is hot. Coolant may spray out and cause
serious burns and other injuries.
- Slowly and carefully turn the cap on the coolant expansion tank anticlockwise
while exerting gentle downward pressure on the cap.
- Always protect the face, hands and arms from hot coolant or steam with a large,
thick cloth.
•When refilling, do not spill any service fluids on engine components or on the exhaust
system. The spilt service fluids can start a fire.
WARNING
High voltages in the electrical system can cause electric shocks, burns, serious injuries
and death!
•Never short circuit the electric system. The 12-volt battery could explode.
•Please note the following guidelines to help reduce the risk of an electric shock and
serious injuries while the engine is running or being started:
- Never touch the electrical wiring of the ignition system.
- Never touch the electrical wiring and connections of gas discharge bulbs.
WARNING

Display
Fig. 225 On the instrument cluster display: the bonnet is open or not closed properly (illustration).
A symbol in the instrument cluster display ⇒ Fig. 225 indicates if the bonnet is open or is not
closed properly.
Do not drive on! If necessary, lift the bonnet and then close it again.
This symbol is also visible when the ignition is switched off and will go out a few seconds after the
vehicle has been locked when all doors are closed.
The symbol can differ depending on the version of the instrument cluster.
Service fluids and consumables
All service fluids and consumables, e.g. tyres, engine coolant and vehicle batteries, are being
constantly developed. The same applies to toothed belts, engine oils and spark plugs for
combustion engines. For this reason, service fluids and consumables should be replaced at a
qualified workshop. Volkswagen dealerships are kept up to date on all innovations.
If the bonnet is not closed properly, it can open suddenly while you are driving and
completely obscure your view of the road. This can lead to accidents and serious injuries.
•After closing the bonnet, always check that it is properly secured. The bonnet must be
flush with the surrounding body panels.
•If you notice that the bonnet is not closed properly while the vehicle is in motion, stop
the vehicle as soon as possible and close the bonnet.
•Therefore the bonnet should only be opened or closed when you are sure that nobody
is in its path.
WARNING
•The bonnet should only be opened when the wiper arms are flush to the windscreen
and when they are switched off in order to avoid damage to the bonnet and the wiper
arms.
•Always return the wiper arms to the windscreen before starting your journey.
NOTICE
Failure to observe the warning displays could lead to your vehicle breaking down in
traffic, and to accidents and serious injuries.
•Never ignore any warning displays.
•Stop the vehicle as soon as it is possible and safe to do so.
WARNING

With the engine at operating temperature, park the vehicle on a level surface to ensure
that the engine oil reading is correct.
Switch off the engine and wait a few minutes for the engine oil to flow back into the sump.
Open the bonnet In the engine compartment.
Identify the engine oil filler cap and oil dipstick. The engine oil filler opening bears the
symbol on the cap and the oil dipstick has a coloured handle. If you cannot find the cap
and dipstick please contact a qualified workshop.
Pull the dipstick out of the guide tube and wipe it off with a clean cloth.
Insert the oil dipstick into the guide tube again as far as it will go. If there is a marking on
the upper end of the oil dipstick, this marking must fit in the corresponding groove at the
top end of the guide tube when inserting.
After reading off the oil level, push the oil dipstick back into the guide tube as far as it will
go.
Unscrew the engine oil filler opening cap .
Only the engine oil expressly approved by Volkswagen for this engine should be gradually
refilled in small quantities (no more than 0.5 l).
In order to avoid overfilling, wait for approximately one minute after each refill step to allow
the engine oil to flow into the oil sump up to the marking on the engine oil dipstick.
Read the engine oil level from the dipstick again before refilling with a further small
quantity of engine oil. Never overfill with engine oil .
After refilling, the engine oil level should be in the middle of area Ⓒ. It should not be above
Ⓒ, in area Ⓑ, and must not reach area Ⓐ .
If too much engine oil has been added unintentionally and the engine oil level is in area Ⓐ,
do not start the engine. Inform a qualified workshop and possibly seek expert assistance.
After refilling, close the engine oil filler opening with the cap.
Insert the oil dipstick into the guide tube as far as it will go. If there is a marking on the
upper end of the oil dipstick, this marking must fit in the corresponding groove at the top
end of the guide tube when inserting.
Close the bonnet In the engine compartment.
Do not refill engine oil.
Engine oil level OK.
Engine oil level too low – refill engine oil.
Checklist
Carry out the steps in the specified order ⇒:
Pull the dipstick out again and read the engine oil level on the dipstick as follows: Ⓐ Engine
oil level too high. Follow any messages that are shown on the instrument cluster display and
go to a qualified workshop . Ⓑ Do not fill the engine oil . Continue to step 16. Ⓒ Engine oil
level OK. Engine oil can, e.g. in the case of high engine loads , be filled up to the upper limit
of this range. Continue to step 8 or 16. Ⓓ Engine oil level is too low. The engine oil must be
refilled. Continue to step 8.
The engine oil level must never be above area ⇒ Fig. 227Ⓑ. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the exhaust system.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Engine oil can ignite if it comes into contact with hot engine components. It can cause
fires, burns and other serious injuries.
•If engine oil is spilt on cold engine parts it can heat up and ignite when the engine is
running.
•Always ensure that the engine oil filler cap is securely tightened after refilling, and that
the dipstick is properly inserted back into the guide tube. This will prevent the engine
oil from draining out on to hot engine components when the engine is running.
WARNING
•If too much engine oil has been added unintentionally and the engine oil level is in area
⇒ Fig. 227Ⓐ, do not start the engine. Inform a qualified workshop and possibly seek
expert assistance. The catalytic converter and the engine could otherwise be damaged.
•When topping up service fluids, please ensure that you pour the correct service fluids
into the correct openings. The use of incorrect service fluids could result in serious
malfunctions and engine damage.
NOTICE

Dispose of the 12-volt vehicle battery in accordance with the regulations. 12-volt vehicle
batteries may contain toxic substances such as sulphuric acid and lead.
Electrolyte can pollute the environment. Clean up any service fluid leakages and dispose of
them properly.

Introduction
This chapter contains information on the followingsubjects:
⇒ Types of tyre monitoring systems
⇒ Tyre Pressure Loss Indicator
⇒ Tyre Pressure Monitoring System
⇒ Troubleshooting for the Tyre Pressure Loss Indicator
⇒ Troubleshooting for the Tyre Pressure Monitoring System
The tyre monitoring system warns the
driver when the tyre pressures get too
low.
Incorrectly securing the battery and using incorrect 12-volt vehicle batteries can cause
short circuits, fire and serious injuries.
•Always use maintenance-free and leak-proof 12-volt vehicle batteries that have the
same properties, specifications and dimensions as the factory-fitted 12-volt vehicle
battery.
•In vehicles with the 12-volt vehicle battery in the luggage compartment, ensure that the
breather hose is connected properly to the 12-volt vehicle battery. Make sure that no
open gas discharge openings are located in the area around the positive battery
terminal. If there is an open breather opening in this area, it must be closed off with a
sealing plug. The breather hose must be connected to the open breather opening in the
area of the negative terminal.
WARNING
A highly explosive mixture of gases is given off when the 12-volt vehicle battery is being
charged.
•12-volt vehicle batteries should only be charged in well-ventilated spaces.
•Never charge a 12-volt vehicle battery that is frozen or that has thawed. Discharged 12-
volt vehicle batteries can already freeze at temperatures of around 0°C (+32°F).
•The 12-volt vehicle battery must be replaced if it has ever been frozen.
•Incorrectly connected cables can cause a short circuit. First connect the positive cable
and then the negative cable.
WARNING
•Never connect or disconnect 12-volt vehicle batteries if the ignition is switched on or
the engine is running. Never use a 12-volt vehicle battery that does not correspond with
the vehicle's specifications. This can damage the electrical system or electronic
components, which can cause electrical faults.
•Never connect equipment that supplies electric power, such as solar panels or a
battery charger, to the 12-volt socket or to the cigarette lighter to charge the 12-volt
vehicle battery. This can damage the vehicle electrical system.

Tyre damage
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Damage to tyres and wheel rims is often hidden ⇒.
•If you suspect that a wheel is damaged, stop the vehicle as soon as it is safe to do so.
•Check the tyres and rims for damage.
•If a tyre is damaged, do not drive on. Seek expert assistance.
•If there is no visible damage, drive slowly and cautiously to the next qualified workshop in order
to have the vehicle checked.
Foreign bodies in the tyre
•Leave the foreign body in the tyre if it has entered the inner tyre. Foreign bodies that are stuck
between the tyre tread blocks can be removed.
•Replace the damaged wheel ⇒ Changing a wheel or seal the tyre with the breakdown set and
inflate it ⇒ Breakdown set. Seek professional assistance for this if necessary.
•Check and adjust the tyre pressure.
•Go to a qualified workshop. Volkswagen recommends using a Volkswagen dealership for this
purpose.
Tyre wear
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Wheel imbalance may develop when the vehicle is driven; you will notice this by nervous steering
response. Unbalanced wheels will affect the level of tyre wear. In this case the wheels should be
balanced again.
Incorrect wheel alignment causes excessive tyre wear, impairing the safety of the vehicle. The
wheel alignment should be checked by a qualified workshop if tyres show excessive wear.
Spare wheel or temporary spare wheel
Fig. 239 In the luggage compartment: handwheel for securing the spare wheel.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Worn tyres are a safety risk and can lead to a loss of control of the vehicle and cause
serious injury.
•Tyres must be replaced at the latest when the tread is worn down to the tread wear
indicators.
•Worn tyres have considerably less grip, particularly on wet roads, which can cause the
vehicle to glide along the road surface (aquaplaning).
•Worn tyres reduce the possibility of controlling the vehicle well in normal and difficult
driving situations and increase braking distance and the risk of skidding.
WARNING
If you notice unusual vibration or the car pulling to one side while the vehicle is in motion,
this may indicate that one of the tyres is damaged.
•Reduce speed immediately and park the vehicle without obstructing traffic.
•Check the tyres and rims for damage.
•Never drive on if wheels or tyres are damaged. Seek expert assistance instead.
•If there is no visible damage, drive slowly and cautiously to the next qualified
workshop in order to have the vehicle checked.
