Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Lighting
Vehicle lighting not working partially or completely. A separate display appears in the
instrument cluster if there is a cornering light fault.A trailer turn signal or all trailer lights have
stopped working.
Check the exterior lighting and change the appropriate bulb as required ⇒ Changing bulbs. If all
bulbs are OK or there is a fault in the dynamic cornering light, go to a qualified workshop.
Monitoring the lights on a connected trailer
For vehicles with a factory-fitted towing bracket, the vehicle will also monitor certain bulbs on a
trailer which has been connected properly via the trailer socket.
If a trailer turn signal or all the trailer lights fail, the indicator lamp in the instrument cluster will
go out.
Changing fuses
Introduction
This chapter contains information on the followingsubjects:
⇒ Fuses in the dash panel
⇒ Fuses in the engine compartment
⇒ Fuse table for fuses in the dash panel
⇒ Fuse tables for fuses in the engine compartment
⇒ Changing a blown fuse
At the time of print we are unable to provide an complete overview of the locations of the fuses for
the electrical consumers. This is because the vehicle is under constant development, because
fuses are assigned differently depending on the vehicle equipment level and because several
consumers may use a single fuse. You can get more information about the fuse layout from a
Volkswagen dealership.
Several electrical consumers could share a single fuse. Conversely, a single consumer could have
more than one fuse.
Therefore fuses should only be replaced when the cause of the fault has been rectified. If a new
fuse blows shortly after insertion, have the electrical system checked by a qualified workshop as
soon as possible.

•Connect the other end of the red jump lead to the positive terminal (+) of the vehicle battery

Tow-starting or towing
Introduction
This chapter contains information on the followingsubjects:
⇒ Notes on tow-starting and towing
⇒ Fitting the rear towing eye
⇒ Fitting the front towing eye
⇒ Fitting the front towing eye (R-Line)
⇒ Driving notes when towing
Tow-starting is where a vehicle is started from it being set in motion by a vehicle that is hitched up
to it.
Towing is where a vehicle that cannot be driven is pulled away with the aid of another vehicle.
Observe any legal requirements when towing or tow-starting.
For technical reasons, vehicles with a discharged 12-volt battery must not be towed.⇒ Jump 
starting
Vehicles with Keyless Access must only be towed with the ignition switched on.
Towing a vehicle when the engine is switched off and the ignition is switched on discharges the 12-
volt vehicle battery. Depending on the charge level of the 12-volt vehicle battery, the drop in voltage
can be large enough after just a few minutes that electrical consumers in the vehicle will no longer
function, e.g. the hazard warning lights.
Jump starting the vehicle incorrectly can cause the 12-volt vehicle battery to explode,
which can lead to serious injuries. Please observe the following in order to reduce the risk
of the 12-volt vehicle battery exploding:
•All work on the 12-volt vehicle battery and the electrical system can cause serious
chemical burns, fire or electric shocks. Always read the warnings and safety
information before carrying out any kind of work on the 12-volt vehicle battery ⇒ 12-
volt vehicle battery.
•Always wear suitable eye protection and gloves and never lean over the 12-volt vehicle
battery.
•Attach the connector cables in the correct order – the positive cable first, followed by
the negative.
•Never connect the negative cable to parts of the fuel system or to the brake lines.
•The non-insulated parts of the battery clamps must not be allowed to touch. The jump
lead attached to the positive terminal on the 12-volt vehicle battery must not touch
electrically conductive parts of the vehicle.
•m/k/a995MK Vehicles with battery in the engine compartment: check the battery
window on the 12-volt vehicle battery. Use a torch for this if necessary. If the display is
light yellow or colourless, do not jump start the vehicle. Seek expert assistance.
•Avoid electrostatic discharge in the vicinity of the 12-volt vehicle battery. The explosive
gas emitted from the 12-volt vehicle battery could be ignited by sparks.
•Do not carry out jump starting if the 12-volt vehicle battery is damaged or if it is or has
ever been frozen.
WARNING
Once the vehicle has been successfully jump-started, go to a qualified workshop and have
the 12-volt vehicle battery checked.
NOTICE

Fig. 222 Front bumper, right-hand side: screwing in the towing eye.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The towing eye is screwed into a threaded hole behind a cover on the right of the front bumper
⇒ Fig. 221.
The towing eye must always be kept in the vehicle.
Observe the notes on towing ⇒ Notes on tow-starting and towing.
Fitting the towing eye at front
•Remove the towing eye from the vehicle tool kit in the luggage compartment.
•Push the area of the cover pointing towards the vehicle ⇒ Fig. 221 in the direction of the arrow
to release the cover fastener.
•Remove the cover and leave it hanging from the vehicle.
•Turn the towing eye anti-clockwise into the threaded hole and tighten as far as possible
⇒ Fig. 222⇒. Use a suitable object to screw the towing eye fully and securely into the
mounting.
•After you have finished towing, remove the towing eye by unscrewing it with a suitable object
clockwise.
•Insert the lug on the cover on the opening pointing towards the vehicle side in the bumper and
push on the opposite area of the cover until the lug engages in the bumper.
•If necessary clean the towing eye and place them back in the vehicle tool kit in the luggage
compartment.
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

Allow the engine to cool sufficiently.
Children and other people should be kept well away from the engine compartment.
Ensure that the vehicle cannot roll away unexpectedly.
Opening and closing the bonnet

Opening the bonnet
•Ensure that the wiper arms are positioned on the windscreen before opening the bonnet ⇒.
•Open the driver door and pull the release lever in the direction of the arrow ⇒ Fig. 223. The
bonnet is released from its lock by a spring mechanism ⇒.
•Lift the bonnet at the opening lever ⇒ Fig. 224 (arrow) and open fully. The bonnet is held in the
open position by the gas strut.
Closing the bonnet
•To close the bonnet, pull it down to overcome the gas strut pressure ⇒.
•Let the bonnet drop into the catches from a height of about 30 cm – do not press it down!
If the bonnet has not closed properly, lift it and then close it again.
The bonnet sits flush with the body parts around it when it is closed properly. The bonnet is no
longer highlighted in the instrument cluster display ⇒ Display or the display goes out.
Ignoring any of the items on this important safety checklist can lead to severe injuries.
•Always follow the instructions in the checklist and observe the general safety
procedures.
WARNING

The use of engine oils compliant with the VW 504 00, VW 507 00 and VW 508 00 specifications
requires a fuel quality compliant with EN 228 (petrol) and EN 590 (diesel), or fuel of an equivalent
quality. Engine oils compliant with VW 504 00, VW 507 00 and VW 508 00 are therefore
unsuitable for use in a large number of markets.
If the engine has been filled with engine oil in accordance with the standards W 502 00, VW 504 00
and VW 507 00, a sticker with the relevant information will be located on the lock carrier in the
engine compartment. Observe this information!

The engine oil VW 502 00 must be used if the fuel grade does not comply with EN 228.
Using VW 504 00 instead of VW 508 00 may cause the vehicle's emissions values to increase
slightly.
You can also check with a qualified workshop if you are unsure whether your vehicle is equipped
with a diesel particulate filter. Volkswagen recommends using a Volkswagen dealership for this
purpose.
Changing the engine oil
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The engine oil must be changed on a regular basis. Always observe the service intervals applicable
for your vehicle ⇒ Service.
The engine oil and filter change should be carried out by a qualified workshop due to the special
tools and knowledge required, this also applies to the disposal of used oil. Volkswagen
recommends using a Volkswagen dealership for this purpose.
Please read the notes on the service intervals ⇒ Service.
Additives in the engine oil can cause new engine oil to discolour quickly. This is normal and does
not mean that the engine oil should be changed more frequently.

Coolant and coolant additives can pollute the environment. Spilt service fluids must be
collected then disposed of properly and in an environmentally responsible way.
Checking the coolant level and refilling coolant
Fig. 229 In the engine compartment: markings on the coolant expansion tank.
Fig. 230 In the engine compartment: coolant expansion tank cap (illustration).
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The warning lamp for the engine coolant will light up if the engine coolant level is too low.
Preparation
•Park the vehicle on a firm and level surface.
•Allow the engine to cool down ⇒.
•Open the bonnet ⇒ In the engine compartment.
•The coolant expansion tank is identified by the symbol on the cap ⇒ Fig. 230.
Checking the coolant level
•When the engine is cold, check the coolant level on the side markings of the engine coolant
expansion tank ⇒ Fig. 229. The engine coolant level must be between the marks.
•Refill coolant if the liquid level in the coolant expansion tank is below the minimum marking
(min). When the engine is warm, the engine coolant level may be slightly above the maximum
(MAX) mark.
Refilling coolant
•Always protect your face, hands and arms from hot coolant or steam by placing a suitable cloth
on the cap of the coolant expansion tank.
•Unscrew the cap carefully ⇒.
•Refill only new coolant according to the Volkswagen specification ⇒ Coolant specification⇒
.
Insufficient anti-freeze in the coolant system can cause the engine to break down and
cause serious injuries.
•Please note that the amount of correct coolant additive used must be sufficient for the
lowest ambient temperature that you expect the vehicle to be exposed to.
•Coolant can freeze at extremely cold outside temperatures, causing the vehicle to
break down. Vehicle occupants with inadequate winter clothing could then freeze to
death as the heating will also no longer function.
WARNING
Never mix genuine coolant additives with other coolants that have not been approved by
Volkswagen. Mixing other coolants could cause serious damage to the engine and cooling
system.
•If the liquid in the coolant expansion tank is not pink (colouring results from mixing the
purple coolant additive with distilled water) but for example, brown instead, - G 13 - has
been mixed with an unsuitable coolant. The coolant must be changed as soon as
possible if this is the case. Failure to observe this point can result in serious faults or
engine damage.
NOTICE

Fig. 231 In the engine compartment: cap on the brake fluid container.
Brake fluid will gradually absorb water from the surrounding air. The brake system will be damaged
if there is too much water in the brake fluid. The boiling point of the brake fluid is also considerably
reduced by the water content. Heavy use of the brakes may cause a vapour lock in the brake
system if the water content is too high. Vapour locks reduce levels of braking power, considerably
increase braking distance and can even cause the brake system to fail completely. Your own safety
and that of other road users depends on having a brake system that functions properly at all times
⇒.
Brake fluid specification
Volkswagen has developed a brake fluid that has been optimised for the brake system in the
vehicle. To ensure optimal operation of the brake system, Volkswagen expressly recommends the
use of brake fluid compliant with VW standard 501 14.
Before using a particular brake fluid, check that the specifications printed on the container
correspond to the vehicle requirements.
Brake fluid that is compliant with VW standard 501 14 is available from Volkswagen dealerships.
If this brake fluid is not available and it is necessary to use another high-quality brake fluid instead,
brake fluid that is compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116 DOT 4 can
be used.
Not all brake fluids that are compliant with DIN ISO 4925 CLASS 4 or US standard FMVSS 116
DOT 4 have the same chemical composition. Some of these brake fluids may contain chemicals
that can damage or destroy brake system components over time.
Volkswagen therefore recommends the use of brake fluid that is compliant with
VW standard 501 14 to ensure sustained optimal operation of the brake system.
Brake fluid that is compliant with VW standard 501 14 fulfils the requirements of DIN ISO 4925
CLASS 4 or US standard FMVSS 116 DOT 4.
Brake fluid level
Brake fluid level is too low. Do not drive on! Check the brake fluid level.
The brake fluid level must always be between the MIN and MAX marking on the brake fluid
reservoir or above the MIN marking ⇒.
The brake fluid level cannot be checked accurately in all models as engine components may
partially conceal the brake fluid container. If the brake fluid level cannot be read exactly, please go
to a qualified workshop.
The brake fluid level drops slightly when the vehicle is being used as the brake pads wear and the
brakes are automatically adjusted.
Changing the brake fluid
The brake fluid should be changed by a qualified workshop. Volkswagen recommends using a
Volkswagen dealership for this purpose. Only brake fluid that conforms with the required
specification should be used.

Brake fluid can pollute the environment. Any spilt service fluids must be cleaned up and
disposed of properly.
12-volt vehicle battery
Introduction
This chapter contains information on the followingsubjects:
⇒ Checking the electrolyte level of the 12-volt vehicle battery
⇒ Charging, replacing, disconnecting and connecting the 12-volt vehicle battery
⇒ Troubleshooting
The 12-volt vehicle battery is a component of the electrical system and serves to supply power in
the vehicle.
You should only carry out work on the electrical system 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 ⇒. All work should be carried out by a qualified workshop. Volkswagen recommends
using a Volkswagen dealership for this purpose.
Location of the 12-volt vehicle battery
Depending on the vehicle equipment level, the 12-volt vehicle battery may be located in the engine
compartment or in the luggage compartment under the luggage compartment floor.
Explanation of the warnings on the 12-volt vehicle battery
m/k/n948MKAlways wear eye protection!m/k/n947MKElectrolyte is very corrosive
and caustic. Always wear protective gloves and eye protection!m/k/n944MKNo fires,
sparks, naked lights or smoking!m/k/n946MKA highly explosive mixture of gases is given

from battery acid and the 12-volt vehicle battery!m/k/n949MKAlways observe the owner's
manual!
Brake failure or reduced braking effect can be caused by the brake fluid level being too
low or by brake fluid that is too old or unsuitable.
•The brake system and brake fluid level must be checked regularly.
•The brake fluid should be changed regularly.
•Heavy use of the brakes may cause a vapour lock if the brake fluid is left in the system
for too long. Vapour locks reduce levels of braking power, considerably increase
braking distance and can cause the brake system to fail completely.
•Please ensure that the correct brake fluid is used. Only use brake fluid that is explicitly
compliant with VW standard 501 14.
•Any other brake fluid or a low-quality one can affect the functioning of the brakes and
reduce their effectiveness.
•If a brake fluid compliant with VW standard 501 14 is not available, use a high-quality
brake fluid compliant with DIN ISO 4925 CLASS 4 or the US standard FMVSS 116 DOT
4, but only in exceptional circumstances.
•The refilled brake fluid must be new.
WARNING
Brake fluid is toxic.
•In order to reduce the risk of poisoning, never use bottles or other containers to store
brake fluid. There is always a risk of someone drinking from such containers, even if
they are labelled appropriately.
•Brake fluid must always be stored in its original sealed container and kept out of the
reach of children.
WARNING
Brake fluid that has leaked or been spilt can damage the vehicle paintwork, plastic parts
and tyres. Wipe off brake fluid that has leaked or been spilled immediately from all parts of
the vehicle.
