engine VOLKSWAGEN T-ROC 2021 Owner´s Manual

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.

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.
Coded vehicle keys are available from a Volkswagen dealership.

Problem-free operation of the vehicle is guaranteed only with Volkswagen Genuine vehicle keys.

Fig. 104 Gear shift pattern of a 6-speed manual gearbox.
Selecting a forward gear
The positions of the individual driving gears are shown on the gearshift
lever ⇒ Fig. 103  or ⇒ Fig. 104 .
Fully depress and hold the clutch pedal.
Move the gear lever to the required position ⇒ .
Release the clutch to engage.
In some countries, the clutch pedal will have to be depressed fully in order to start the engine.
Selecting reverse gear
Reverse gear should be selected only when the vehicle is stationary.
Fully depress and hold the clutch pedal ⇒ .
Move the gear lever to the neutral position and push down.
Push the gear lever fully to the left and then to the front into the reverse gear position ⇒ Fig. 103Ⓡ 
or ⇒ Fig. 104Ⓡ .
Release the clutch to engage.
Shifting down
Shifting down when the vehicle is in motion should always take place to the next lower gear and
avoiding high engine speeds ⇒ . At high speeds or high engine speeds, damage to the clutch and
the gearbox could occur if one or more gears are skipped when shifting down gear, even if the clutch
is not released when doing this ⇒ .

WARNING
Rapid acceleration can cause loss of traction and skidding, particularly on slippery roads. This can
cause you to lose control of the vehicle, which can lead to accidents and serious injuries.

Use fast acceleration only if visibility, weather, road and traffic conditions permit, and other road
users are not put at risk due to the acceleration and driving style.
Always adjust your driving style in accordance with the flow of traffic.
When the TCS is switched off, the drive wheels may spin, especially if the road surface is wet,
slippery or dirty. This may result in you no longer being able to steer or control the vehicle.

WARNING
When the engine is running, the vehicle will start to move as soon as a gear is engaged and the
clutch is released. This also applies when the electronic parking brake has been switched on.
Never engage reverse gear while the vehicle is in motion.

WARNING
Shifting gears incorrectly to gears that are too low can lead to a loss of control over the vehicle, with
accidents and serious injuries as a consequence.

NOTICE
Serious damage to the clutch and gearbox could occur if the gear lever of the manual gearbox is
shifted to a gear which is too low when travelling at high speeds or at high engine speeds. This also
applies if the clutch remains depressed and the gears do not engage.

NOTICE
Please note the following points in order to avoid damage and premature wear:
Do not rest your hand on the gear lever when driving. The pressure from your hand is passed onto
the selector forks in the gearbox.
Ensure that the vehicle has come to a full stop before engaging reverse gear.
Always fully depress the clutch pedal when changing gear.
Do not hold the vehicle by riding the clutch on uphill gradients with the engine running.

Changing up a gear early will help to save fuel and minimise engine noise.
