ignition VOLKSWAGEN T-ROC 2021 Owner´s Manual

Never leave the vehicle unattended with the engine running, particularly if a gear or driving position
has been selected. The vehicle could move suddenly or something unexpected may happen that may
cause damage, fire and serious injuries.
Never use a start booster. Start boosters could explode and cause the engine to suddenly run at high
revs.

WARNING
Never leave the engine running if you leave the vehicle unattended, particularly if a gear or position
has been selected. The vehicle could move suddenly or something unexpected may happen that may
cause damage, fire or serious injuries.

WARNING
Start boosters could explode or cause the engine to suddenly run at high revs.
Never use a start booster.

NOTICE
The starter and the engine can be damaged if you attempt to start the engine while the vehicle is in
motion or if the engine is started again immediately after it has been switched off.
When the engine is cold, avoid high engine speeds, driving at full throttle and overloading the
engine.
Do not push start or tow start the vehicle. Unburnt fuel could damage the catalytic converter.

NOTICE
If the engine does not start, never use the starter with a gear selected and the vehicle key in the
ignition lock in position ⇒ Fig. 99②  for driving or tow-starting, e.g. when the fuel tank is empty.
This could cause damage to the starter.
Fill up with fuel if necessary ⇒ Fuel types and refuelling  or jump start the vehicle ⇒ Jump starting .
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.

Components with a high power consumption are switched off temporarily when the engine is
started.

The engine cannot be started with the starter button, for example, if the button cell in the vehicle
key is weak or flat. In this case, use the emergency start function ⇒ No valid vehicle key recognised .

When starting from cold, the engine may be a little noisy for the first few seconds. This is quite
normal, and no cause for concern.

At outside temperatures of less than +5°C (+41°F), fumes may be detected under a vehicle with a
diesel engine if the fuel-powered supplementary heater is switched on.
Switching off the engine
Bring the vehicle to a standstill ⇒ .
Park the vehicle ⇒ Parking .
Vehicles with ignition lock: turn the vehicle key to position ⇒ Fig. 99⓪  in the ignition lock.
Vehicles with a starter button: press the starter button briefly ⇒ Fig. 100 . If the engine cannot
be switched off, carry out the emergency switch-off procedure ⇒ Engine cannot be switched off .
Follow the instructions in the instrument cluster ⇒ Instrument cluster .
Ignition warning
In order to indicate an active ignition when leaving the vehicle, an acoustic warning signal sounds
when opening the driver door and corresponding warning messages appear on the display of the
instrument cluster.
Warning before leaving the vehicle
Vehicles with DSG dual clutch gearbox: if the selector lever is not in position P, an acoustic
warning signal will sound when the driver door is opened and the warning message Please move
selector lever to position P. will be shown on the instrument cluster display. In this way, a warning is
given that the vehicle could potentially roll away. When you leave the vehicle, the electronic parking
brake also switches on to prevent the vehicle rolling away.

WARNING
Never switch off the engine while the vehicle is in motion. This can lead to a loss of vehicle control,
accidents and serious injuries.

The airbags and belt tensioners will not work if the ignition is switched off.
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.
Electronic immobiliser
The immobiliser helps to prevent the engine from being started and driven with an unauthorised
vehicle key.
There is a chip in the vehicle key. The immobiliser is automatically deactivated by this when a valid
vehicle key is inserted in the ignition lock.
The electronic immobiliser is automatically activated when the vehicle key is removed from the
ignition lock. In vehicles with Keyless Access, the vehicle key must be outside the vehicle.
The engine can be started only using a Volkswagen Genuine vehicle key with the correct code.

vehicle control, accidents and serious injuries.
The airbags and belt tensioners will not work if the ignition is switched off.
The brake servo will not work when the engine is switched off. That is why more pressure on the
brake pedal is needed to brake the vehicle when the engine is switched off.
The power steering will not work when the engine is not running. More power is needed to steer the
vehicle when the engine is switched off.
When the ignition is switched off, the steering lock may activate and you will no longer be able to
steer the vehicle.
The start/stop system must be deactivated if work is to be carried out in the engine compartment.

NOTICE

gearbox the clutch can be opened at idling speed, thus saving fuel. Thanks to its efficiency, low
weight and intelligent control system, the DSG® dual clutch gearbox usually enables fuel
consumption that is equal to or lower than a manual gearbox.
However, just like the manual gearbox, the clutch in the DSG® dual clutch gearbox is subject to wear.
Regular maintenance is necessary depending on the type of DSG® dual clutch gearbox; further
information ⇒ Scope of service . In the event of a fault in one gear train half, the DSG® dual clutch
gearbox also allows one gear train half to be deactivated and the journey to be continued using the
other gear train half ⇒ Troubleshooting . The gearbox must then be checked as soon as possible by a
qualified workshop.

– Standard forward driving position
Position : Normal programme.
All forward gears are shifted up and down automatically. The timing of the gear shift is determined
by the engine load, your individual driving style and the speed of the vehicle.
Position : Sport programme.
The forward gears are automatically changed up later and down earlier than in selector lever
position D. This exploits the engine’s full power reserves. The timing of the gear shift is determined
by the engine load, your individual driving style and the speed of the vehicle.
To change between positions D and S, move the selector lever to the rear ⇒ Fig. 105 .
The selector lever will always return to selector lever position D/S. That also works in the Tiptronic

To release the selector lever lock, switch on the ignition and depress the brake pedal. Then press the
lock button in the selector lever handle in the direction of the arrow ⇒ Fig. 105 .
The selector lever lock is not engaged if the selector lever is moved quickly through position N, e.g.
when shifting from reverse to D/S. This makes it possible, for instance, to rock the vehicle backwards
and forwards if it is stuck in snow or mud. The selector lever lock engages automatically if the lever is
in position N for more than approximately one second without the brake being pressed and when
the vehicle is travelling no faster than approximately 5 km/h (3 mph).

WARNING
Selecting the wrong position can cause you to lose control of the vehicle, which can lead to accidents
and serious injuries.
Never depress the accelerator when selecting a position.
When the engine is running and a position is engaged, the vehicle will start moving as soon as the
brake pedal is released.
Never shift to reverse or selector lever position P while the vehicle is moving.

Brake request by ACC ⇒ Adaptive Cruise Control (ACC) .
The brake pedal was not depressed or not fully depressed.
Brake immediately.
Gearbox overheated
The indicator lamp lights up yellow.
A signal tone may also be given. A text message may also be shown on the instrument cluster
display.
The DSG® dual clutch gearbox can become too hot, for example, if the vehicle pulls off regularly,
during long periods at crawling speed, or in stop-and-go traffic.
Do not drive on!
Allow the gearbox to cool down in selector lever position P⇒ .
Do not drive on if the indicator lamp does not go out.
Seek expert assistance. Failure to do so could result in considerable damage to the gearbox.
Releasing the selector lever lock manually
If the power fails in the vehicle (for example if the 12-volt vehicle battery is flat) and the vehicle has
to be towed, the selector lever lock must be released manually. Seek expert assistance for this.
The manual release mechanism is located under the cover of the gearshift gate.
Removing the cover of the gearshift gate:
Switch on the electronic parking brake. If the electronic parking brake cannot be switched on, the
vehicle will have to be prevented from rolling away using other means.
Switch off the ignition.
Carefully pull the cover upwards in the area around the selector lever gaiter with connected
electrical wiring ⇒ Fig. 108 .
Pull the cover up and over the selector lever ⇒ .
Depending on the vehicle equipment, there are two possible manual release mechanism variants.
Releasing the selector lever lock manually:
Using the flat blade of the screwdriver from the vehicle toolkit, carefully push the release lever in the
direction of the arrow and keep it in this position ⇒ Fig. 108 .
Press the lock button on the front of the selector lever and move the selector lever into position N.

The downhill speed control cannot hold the vehicle on the gradient in all situations or brake it
sufficiently on all slopes going downhill (e.g. if the ground is slippery or icy).

WARNING
Always be prepared to brake the vehicle. Accidents and injuries could occur if you are not prepared
to brake.
The downhill speed control is only a support function and may not be able to brake the vehicle
sufficiently in all situations when driving downhill.
The vehicle may become faster despite the downhill speed control being in operation.
Steering
Information on steering
The steering should be locked every time you leave the vehicle to make it more difficult for the
vehicle to be stolen.
The steering
The power steering is not hydraulic, but is an electromechanical system. The advantage of this
steering system is that no hydraulic hoses, hydraulic oil, pumps, filter or other parts are required.
The electromechanical system reduces fuel consumption. A hydraulic system requires constant oil
pressure in the system, whereas an electromechanical steering system only needs an energy supply
while steering.
In vehicles with driving profile selection, the selected driving profile can affect the behaviour of the
power steering ⇒ Driving profile selection and 4MOTION Active Control .
Electronic steering column lock in vehicles with a starter button
The steering column will be locked if the driver door is opened when the ignition is switched off. For
this, the vehicle should be stationary and, if necessary, the gear selector lever should be in position
P.
If the ignition is not switched off until after the driver door is opened, the electronic steering column
will only be locked when the vehicle is locked using the sensor in the door handle or the vehicle key.
Mechanical steering column lock (steering lock) in vehicles with an ignition lock
The steering column is locked if the vehicle key is removed from the ignition lock when the vehicle is
stationary. Turn the steering wheel slightly until the steering lock audibly engages.
Insert the vehicle key into the ignition lock to unlock the steering lock. Turn the steering wheel
slightly to relieve the load on the steering lock mechanism. Hold the steering wheel in this position
and turn the ignition on.
