Performance monitor
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The performance monitor is a display
for sporty driving. The digital
instruments display real-time values for
engine power, temperature and
acceleration that are determined by
sensors on the vehicle. This provides
the driver with an overview of driving
dynamics.

Display areas.
Arrow buttons for changing to the lap timer.
Opening the performance monitor
•Press the MENU button on the Infotainment system.
•Touch the Vehicle function button.
•Touch the Selection function button.
•Touch the Sport function button.
If you would like to switch between the performance monitor and the lap timer ⇒ Lap timer, touch
one of the arrow buttons on the left and right above the instruments ⇒ Fig. 27②.
Selecting instruments and setting units
The display can show a maximum of three instruments at the same time. Each instrument can be
selected for each display area ⇒ Fig. 27① (left, middle, rightyf.
To change instruments, swipe vertically over the display. The currently selected instrument will then
disappear and a new instrument will appear.
The units can be adjusted for some instruments in the Infotainment system ⇒ Operation and 
display in the Infotainment system.
The following instruments can be displayed:

engine loads and with high outside temperatures. This is no cause for concern unless the
indicator lamp in the instrument cluster display is lit up or flashing ⇒ Coolant temperature 
display.
•Oil temperature display: the needle is in the middle area under normal driving conditions. If
the needle is in the bottom left area, this means that the engine has not yet reached its
operating temperature. Avoid excessively high speeds and acceleration when the engine has
not yet reached its operating temperature. The needle may move further in a clockwise direction
under high engine loads and at high outside temperatures. This is no cause for concern unless
the indicator lamp in the instrument cluster display is lit up or flashing ⇒ Engine oil.

Warning lamps and text messages may be shown in the instrument cluster display. These warnings
may also be accompanied by acoustic signals.
Engine oil
Lit up: engine oil level too low. Switch off the engine. Check the engine oil level ⇒ Checking 
the engine oil level and refilling the engine oil.Flashing: engine oil system fault. Go to a
qualified workshop and have the engine oil sensor checked.Flashing: engine oil pressure
is too low. Do not drive on!
Switch off the engine and check the engine oil level ⇒ Checking the engine oil level and refilling the 
engine oil - Do not drive on or remain at idling speed if the warning lamp is flashing even if the
engine oil level is correct. The engine could otherwise be damaged. You should obtain professional
assistance.
Engine coolant
Introduction
This chapter contains information on the followingsubjects:
⇒ Coolant specification
⇒ Checking the coolant level and refilling coolant
You should only carry out work on the cooling 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 ⇒. The work should be carried out by a qualified workshop if you are uncertain.
Volkswagen recommends using a Volkswagen dealership for this purpose.
Coolant and coolant additives can pollute the environment. Spilt service fluids must be
collected then disposed of properly and in an environmentally responsible way.
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
40ybFRRODQWDGGLWLYH G 13 (TL-VW 774 Jyf7KHFRRODQWDGGLWLYHLVG\HGSXUSOH7KLVPL[WXUHRI
water and coolant additive gives the necessary frost protection down to -25°C (-13°FyfDQGSURWHFWV
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
40ybHYHQLIDQWLIUHH]HLVQRWUHTXLUHGLQZDUPZHDWKHUDQGZDUPFOLPDWHV.
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 60ybDVWKLVZRXOG

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.
