Driving tips
 Introduction
This chapter contains information on the followingsubjects:
⇒ Preparing for a journey and driving safely
⇒ Driving abroad
⇒ Driving through water on roads
Depending on where the vehicle is used, it may be advisable to have an engine and transmission
guard installed. An engine and transmission guard can reduce the risk of damage to the vehicle's
underbody and engine oil sump, for example when driving over kerbs, driveways or unsurfaced
roads. Volkswagen recommends using a Volkswagen dealership for this purpose.

General information on the heating and fresh air system
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The required interior temperature cannot be lower than the outside temperature as the heating and
fresh air system cannot cool or dehumidify the air.
Settings for optimal road visibility
•Set blower ⇒ Fig. 112② to level 1 or 2.
•Open and position all vents on the dash panel ⇒ Vents.
•Turn the air distribution controller ⇒ Fig. 112③ to the defrost position.
Information on the air conditioning system
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The cooling system for the vehicle interior only works when the engine is running and the blower is
switched on.
The air conditioning system operates most effectively with the windows and the electric panorama
sliding and tilting glass roof closed. However, if the vehicle has heated up after standing in the sun
for some time, the air inside can be cooled more quickly by opening the windows and the electric
panorama sliding and tilting glass roof for a short time.
Settings for optimal road visibility
Switching the cooling system on not only reduces the temperature of the vehicle interior, but also
the humidity. This improves comfort for the vehicle occupants and prevents the windows from
misting when the outside humidity is high.
•Switch off air recirculation mode ⇒ Air recirculation mode.
•Set the blowers to the required level.
•Open and position all vents on the dash panel ⇒ Vents.
•Turn the air distribution controller to the defrost position.
•Press the button to switch the cooling system on. The indicator lamp in the button
lights up.
The cooling system cannot be switched on
The following criteria may prevent the cooling system from being switched on:
•The engine is not running.
•The blower is switched off.
•The air conditioning system fuse has blown.
•The ambient temperature is lower than approximately +2℃ (+36°F).
•The compressor has been temporarily switched off because the coolant temperature is too high.
•There is a different fault in the vehicle. The air conditioning system should be checked by a
qualified workshop.
Things to note
If the humidity and temperature outside the vehicle are high, condensation can drip off the
evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does
not indicate a leak.
The windscreen may mist up after starting the engine due to residual humidity in the air
conditioning system. Switch the defrost function on in order to clear the windscreen of condensation
or mist as quickly as possible.

Changing engine oil
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The engine oil must be changed regularly in accordance with the data given in the service
schedule.
The engine oil and filter should always be changed, and used oil disposed of, by a qualified
workshop due to the special tools and knowledge required. Volkswagen recommends using a
Volkswagen dealership for this purpose.
More details on the service intervals can be found in the service schedule.
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.
Before changing the engine oil, first find out where old oil can be disposed of properly near
you.
Used oil must be disposed of in accordance with regulations governing the protection of the
environment. Never dispose of old oil in locations such as gardens, woods, sewerage systems, on
streets and roads, or in rivers and waterways.
Coolant
 Introduction
This chapter contains information on the followingsubjects:
⇒ Warning lamp for coolant
⇒ Coolant specification
⇒ Checking the coolant level and refilling coolant
Never carry out any work on the engine coolant system if you are not familiar with the requisite
procedures, or if you do not have access to the correct tools, operating equipment and fluids ⇒.
The work should be carried out by a qualified workshop if you are uncertain. Volkswagen
recommends using a Volkswagen dealership for this purpose.
Serious injuries can be caused if work is carried out incorrectly.
Additional information and warnings:
•Preparation for working in the engine compartment ⇒ Preparation for working in the engine
compartment
•Accessories, modifications, repairs and renewal of parts ⇒ Accessories, modifications, repairs
and renewal of parts
If, in exceptional cases, you have to carry out an oil change yourself, please note the
following:
•Always wear eye protection.
•Always allow the engine to cool down completely to avoid burns.
•Keep your arms horizontal when removing the oil drain plug with your fingers to help
prevent oil from running down your arm.
•Use a suitable container when draining the used oil. It must be at least large enough to
hold the entire quantity of engine oil required for refilling.
•Never store engine oil in empty food containers, bottles or any other non-original
containers as people finding these containers may not know that they contain engine oil.
•Engine oil is toxic and must be stored out of the reach of children.
WARNING
Engine coolant is toxic.
•Engine coolant should only be kept in sealed original containers in a safe place.
•Never store engine coolant in empty food containers, bottles or any other non-original
containers as people finding these containers may then drink the engine coolant.
•The engine coolant must be stored out of the reach of children.
•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

Coolant and coolant additives can pollute the environment. Spilt operating fluids must be
collected and disposed of properly and with respect for the environment.
Warning lamp for coolant
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Several warning and indicator lamps will light up briefly as a functional check when the ignition is
switched on. They will switch off after a few seconds.
Lit upPossible causeSolution
Engine coolant temperature is
too low in vehicles with natural
gas engine.
Avoid high engine speeds and heavy engine loads.
FlashesPossible causeSolution
Coolant temperature too high.
Do not drive on!
Stop the vehicle as soon as possible, and when
safe to do so. Switch off the engine, leave the
engine to cool down.
Coolant level too low.
Do not drive on!
After the engine has cooled down, check the
coolant level and refill engine coolant if the level is
too low ⇒ Checking the coolant level and refilling
coolant.
With display --.- in the
instrument cluster:
fault in the engine cooling
system.
Do not drive on!
Seek expert assistance.
In some vehicles, the coolant temperature display may be displayed on the screen of the
portable navigation device (delivered by Volkswagen) ⇒ Accessories, modifications, repairs and
renewal of parts.
Coolant specification
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The cooling system is filled at the factory with a mixture of specially prepared water and at least
40% coolant additive G 13 (TL-VW 774 J). The coolant additive is dyed purple. This mixture of
water and coolant additive gives the necessary frost protection down to -25°C (-13°F) and protects
the alloy parts of the cooling system against corrosion. The mixture also prevents scaling and
raises the boiling point of the coolant.
In order to protect the coolant system, the proportion of coolant additive must always be at least
40%, even if anti-freeze is not required in warm weather and warm climates.
If greater frost protection is required in very cold climates, the proportion of anti-freeze additive can
be increased. However, the percentage of coolant additive should not exceed 60%, as this would
reduce the frost protection and the cooling effect.
When topping up the coolant, a mixture of distilled water and at least 40% coolant additive - G 13 -
or - G 12 plus-plus - (TL-VW 774 G) (both of which are dyed purple) must be used in order to obtain
the optimum corrosion protection ⇒. Mixing - G 13 - with the coolant additives - G 12 plus - (TL-
VW 774 F), - G 12 - (dyed red) or - G 11 - (dyed blue-green) will significantly decrease the level of
corrosion protection and should therefore be avoided ⇒.
Failure to observe the warning lamps could lead to your vehicle breaking down in traffic, and
to accidents and serious injuries.
•Always observe any warning lamps that are lit up.
•Never ignore any warning lamps that are lit up.
•Stop the vehicle as soon as possible and when safe to do so.
WARNING
Failure to observe the illuminated indicator lamps could lead to the vehicle being damaged.
NOTICE

Coolant and coolant additives can pollute the environment. Spilt operating fluids must be
collected and disposed of properly and with respect for the environment.
Checking the coolant level and refilling coolant
Fig. 123 In the engine compartment: marking on the coolant expansion tank
Fig. 124 In the engine compartment: coolant expansion tank cap
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 ⇒ .
•The coolant expansion tank has the symbol on its cap ⇒ Fig. 124.
Checking the coolant level
•Check the coolant level at the side marking of the expansion tank when the engine is cold
⇒ Fig. 123.
•Refill the coolant if the liquid level is below the minimum marking (min). When the engine is
warm, the coolant level may be slightly above the top end of the marked area.
Refilling coolant
•Always protect your hands and arms from hot coolant or steam by placing a suitable cloth on
the cap of the coolant expansion tank.
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 brown instead of purple, for example, - G 13 -
has been mixed with another unsuitable engine 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

Service fluids and consumables
First read and observe the introductoryinformation and safety warnings⇒
Introduction
All service fluids and consumables, e.g. toothed belts, tyres, coolant, engine oil, spark plugs and
vehicle batteries, are being constantly developed. For this reason, service fluids and consumables
should be replaced at a qualified workshop. A Volkswagen dealership is always kept up to date on
innovations.
Leaking service fluids can pollute the environment. Spilt service fluids must be collected in
suitable containers and disposed of properly and with respect for the environment.
Repairs and technical modifications
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Repairs and modifications must always be carried out according to Volkswagen specifications⇒
.
