ignition VOLKSWAGEN T-ROC 2019 Repair Manual

WARNING
New brake pads will not have the optimal braking effect when first fitted.
New brake pads cannot generate the full braking effect during the first 300 km and must first be run
in. A reduced braking effect can be increased by applying more pressure to the brake pedal.
In order to reduce the risk of accidents, serious injuries and the loss of control over the vehicle, you
must drive particularly carefully when driving with new brake pads.
Never drive too close to other vehicles during the run-in time for the new brake pads and never
create a driving situation that will place a heavy load on the brakes.

WARNING
Overheated brakes reduce the braking effect and considerably increase the braking distance.
When driving downhill, the brakes are placed under particular strain and become hot very quickly.
Before driving down a long, steep gradient, reduce speed and change to a lower gear (with manual
gearboxes or in Tiptronic mode with the automatic gearbox). This will make use of the engine
braking effect and relieve the load on the brakes.
Non-standard or damaged front spoilers could restrict the airflow to the brakes and cause them to
overheat.

WARNING
Wet brakes or brakes coated with ice or road salt react more slowly and require longer braking
distances.
Carefully apply the brakes to test them.
Always dry brakes and clean off any coating of ice and salt with a few cautious applications of the
brake when visibility, weather, road and traffic conditions permit.

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.

If the engine does not start, seek expert assistance.

Do not warm up the engine by running it while the vehicle is stationary. Instead, pull off as soon as
there is good visibility through the windows. This helps the engine reach operating temperature
faster and reduces emissions.

The brake servo will not work when the engine is switched off. More force is required on the brake
pedal to stop the vehicle.
If the vehicle key is removed from the ignition, the steering lock may activate and you will no longer
be able to steer the vehicle.

WARNING
The components of the exhaust system become very hot. This can cause fires and serious injuries.
Never park the vehicle so that parts of the exhaust system can come into contact with any
inflammable material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt fuel etc.
Never apply additional underseal or anti-corrosion coatings to the exhaust pipes, catalytic
converters, heat shields or particulate filter.

NOTICE
If the vehicle has been driven at high load for a long period, the engine can overheat when it is
switched off. In order to avoid damage to the engine, allow the engine to run in neutral position for
approximately 2 minutes before switching it off.

After the engine is switched off, the radiator fan in the engine compartment may run on for some
minutes, even if the ignition is switched off or the vehicle key has been removed. The radiator fan
will switch itself off automatically.
