2021 VOLKSWAGEN T-ROC service indicator

When accelerating on a slippery surface, for example on ice and snow, accelerate carefully. The
wheels can spin even when brake support systems are active, and this can lead to a loss of control of
the vehicle.

WARNING
The effectiveness of ESC can be reduced considerably if other components and systems which affect
driving dynamics are not serviced properly or are not functioning properly. This also applies, but not
exclusively, to the brakes, tyres and other named systems.
Please always bear in mind that modifications and changes to the vehicle can affect the way brake
support systems operate.
Alterations to the suspension or the use of non-approved wheel and tyre combinations can affect
the function of brake support systems and reduce their effectiveness.
Suitable tyres support the effectiveness of ESC.

WARNING
Driving without the brake servo can considerably increase the braking distance and thus cause
accidents and serious injuries.
Never switch the engine or ignition off while the vehicle is in motion.
If the brake servo does not function or the vehicle is being towed, the brake pedal will have to be
depressed more forcefully as the braking distance will be increased due to the lack of assistance for
the brake system.
Switching the TCS on and off
Switch off the traction control system (TCS) if the vehicle does not have sufficient traction:
When driving in deep snow or on loose surfaces.
When rocking the vehicle free if it is stuck.
Then switch on TCS again.
Switching TCS on and off
TCS can be switched off and on in the Infotainment system ⇒ Infotainment system controls and
displays .
When the TCS is switched off, the yellow indicator lamp lights up on the instrument cluster
display.
As soon as the TCS starts regulating, the indicator lamp flashes yellow.

Fuel standards
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Petrol
EN 228
DIN 51626-1
Diesel
EN 590
EN 590
Where fuel complying with the specified standard is not available, your Volkswagen dealership or a
qualified workshop will have information on which available fuels are suitable for the vehicle.

NOTICE
Using fuel that does not comply with these standards may reduce performance and cause damage to
the engine and fuel system.

and engine failure.
Petrol
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Fill vehicles with a petrol engine only with unleaded petrol or petrol with a maximum ethanol
content of 10 % (E10) ⇒ .
Fuel grades differ according to the octane number. The vehicle may be filled with petrol that has a
higher octane number than the engine requires. However, this does not provide any advantage in
terms of fuel consumption or engine output.
The fuel quality affects the running properties, performance and service life of the engine. Refuel
with fuel that already contains suitable service additives ⇒ .
Information on the fuel standards can be found in the chapter on fuel standards ⇒ Fuel standards .

NOTICE
Errors during refuelling or unsuitable fuel additives may cause damage to the vehicle.

Engine oils are constantly being developed and improved. Volkswagen dealerships always have the
latest information about any changes. Volkswagen therefore recommends having engine oil changes
done by a Volkswagen dealership.
Information for warning and indicator lamps lit up can be found in the troubleshooting at the end of
the chapter ⇒ Troubleshooting .

WARNING
Incorrect handling of engine oil can cause serious burns and other injuries.

Leaking or spilt engine oil can pollute the environment. Spilt service fluids must be collected and
then disposed of properly and in an environmentally responsible way.
Engine oil standards
First read and observe the introductoryinformation and safety warnings⇒Introduction 
If possible, use only Volkswagen-approved engine oil ⇒ . To comply with the requirements of the
flexible oil change service, use only approved flexible service engine oil that complies with the
corresponding VW standard.
Since the quality of fuels can vary greatly between individual markets, this must be taken into
account when selecting the correct engine oil.
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!

Do not work on the electrical system unless you are familiar with the task, aware of the general
safety procedures and have the correct equipment, service fluids and suitable tools. Serious injuries
can be caused by carrying out work incorrectly ⇒ . All work should be carried out by a qualified
workshop. Volkswagen recommends using a Volkswagen dealership for this purpose.
Information for warning and indicator lamps lit up can be found in the troubleshooting at the end of
the chapter ⇒ Troubleshooting .
Location of the 12-volt vehicle battery
The 12-volt vehicle battery is located in the engine compartment.
Explanation of the warnings on the 12-volt vehicle battery
Always wear eye protection!Electrolyte is very corrosive and caustic. Always wear
protective gloves and eye protection!Fire, sparks, naked lights and smoking are prohibited!
A highly explosive mixture of gases is given off when the 12-volt vehicle battery is charging!
Always keep children away from electrolyte and the 12-volt vehicle battery!Always
observe the owner's manual!

WARNING
Any work on the 12-volt vehicle battery and the electrical system can cause serious chemical burns,
fire or electric shocks. Always read and observe the following warnings and safety information
before carrying out any kind of work:

Various indicator lamps may light up after the 12-volt vehicle battery has been connected and the
ignition is switched on. They will go out when you drive a short distance at a speed of approximately
15 – 20 km/h (10 – 12 mph). If the indicator lamps remain lit up, the vehicle should be checked by a
qualified workshop.
If the 12-volt vehicle battery was disconnected for an extended period, the system may not able to
calculate or correctly display the time when the next service is due ⇒ Instrument cluster . Observe
the maximum permissible service intervals ⇒ Service .
Automatic switch-off for electrical consumers
The intelligent vehicle electrical system management function automatically implements a range of
measures to prevent the 12-volt vehicle battery from discharging under high loads:


power supply to the 12-volt socket and the cigarette lighter may be interrupted temporarily
while the engine is being started.
The vehicle electrics management system cannot always prevent the 12-volt vehicle battery from
being discharged, for example if the ignition is left on over a long period with the engine off or the
side lights or parking lights are left on over a long period of time.

Useful information about wheels and tyres
Introduction
This chapter contains information on the followingsubjects:
⇒ Handling wheels and tyres 
⇒ Wheel rims and wheel bolts 
⇒ Tyre pressure 
⇒ Tread depth and wear indicators 
⇒ Tyre damage 
⇒ Spare wheel or temporary spare wheel 
⇒ Tyre lettering and tyre type 
⇒ Maximum load and speed range for tyres 
⇒ Winter tyres 
⇒ Snow chains 
The tyres are the most heavily loaded and most underestimated parts of a vehicle. Tyres are very
important as the narrow tyre contact surfaces are the only contact between the vehicle and the
road.
The service life of tyres is dependent on tyre pressure, driving style, handling and correct fitting.

WARNING
New tyres or tyres which are old, worn down or damaged cannot provide full vehicle control and
braking efficiency.

the same tread pattern.

the tyre pressure is too low, it is possible that the tyre temperature will increase to such an extent
when driving that the tread peels off and the tyre bursts.
