2021 VOLKSWAGEN T-ROC running

Always ensure that all windows are free of ice, snow and mist to ensure good visibility.
Maximum heat output and the fastest possible defrosting of the windows are possible only when
the engine is running. Do not start your journey until you have good visibility.
To help ensure good visibility, make sure that you use the air conditioning system and the rear
window heating correctly.
Auxiliary heater and ventilation
Introduction
This chapter contains information on the followingsubjects:
⇒ Switching the auxiliary heater and ventilation on and off 
⇒ Programming the auxiliary heater and ventilation 
⇒ Remote control 
The auxiliary heater and ventilation system can be used to heat the vehicle interior in the winter and
ventilate it in the summer. It is able to clear ice, condensation and a thin layer of snow from the
windscreen. The auxiliary heater is supplied with fuel from the vehicle fuel tank and can be operated
when the vehicle is stationary with the ignition switched off. The auxiliary ventilation system is
powered by the 12-volt vehicle battery.
Auxiliary heater exhaust system
The emissions generated by the auxiliary heater are discharged via an exhaust pipe underneath the
vehicle. The exhaust pipe must not be blocked by snow, mud or other objects.

WARNING
Among other things, the emissions from the auxiliary heater contain carbon monoxide, which is an
odourless and colourless poisonous gas. Carbon monoxide can cause people to lose consciousness. It
can also cause death.
Never switch on the auxiliary heater when the vehicle is in unventilated or closed rooms nor let the
auxiliary heater run in unventilated or closed rooms.
Never program the auxiliary heater so that it is switched on and runs in unventilated or closed
rooms.

WARNING
Parts of the auxiliary heater exhaust system become very hot. This can cause fires.
Park the vehicle so that no part of the exhaust system can come into contact with any inflammable
material underneath the vehicle, e.g. dry grass.

Before programming, check that the date and time set in the vehicle are correct ⇒ Time .
Open the Auxiliary heater menu.
Touch the Set function button.
Select one of the memory locations for a Departure time.
Touch the Activate function button.
Manual air conditioning system: the programmed departure time determines the time at which
the auxiliary heater or ventilation should switch off. The point at which the heating or ventilation
process starts is determined depending on the programmed running time.
Climatronic: on the basis of the programmed departure time, the vehicle automatically
calculates the start time for heating or ventilation to the currently set temperature depending on
the outside temperature.
Press the Running time function button under Adjust in order to select the running time when the
auxiliary heater is switched on using the immediate heat button or remote control.
Checking programming
If a departure time has been activated, the LED in the immediate heat button will light up on the
Climatronic control panel for approximately 10 seconds after the ignition is switched off.

WARNING
Never program the auxiliary heating system so that is switched on and run in unventilated or
enclosed spaces. Among other things, the emissions from the auxiliary heater contain carbon
monoxide, which is an odourless and colourless poisonous gas. Carbon monoxide can cause people
to lose consciousness. It can also cause death.
Remote control

First read and observe the introductoryinformation and safety warnings⇒Introduction 

Accidents and injuries can occur if the driver is distracted. Operating the Infotainment system can
distract you from the road.
Always drive carefully and responsibly.
Information on the brakes
New brake pads cannot generate the full braking effect during the first 200 to 300 km and must first
be run in ⇒ . The slightly reduced brake pressure can however be compensated for by increasing
pressure on the brake pedal. During the run-in period, the braking distance is longer for full or
emergency braking than when the brake pads have been run in. In the run-in period, full braking
should be avoided and also situations that create a heavy load on the brakes, e.g. when driving up
close to the vehicle ahead.
The wear of the brake pads depends to a great extent on the conditions under which the vehicle is
operated and the way the vehicle is driven. If the vehicle is used for regular urban trips, short
journeys, and is driven with a sporty driving style, the brake pads must be regularly checked by a
qualified workshop.
When driving with wet brakes, for example after driving through water, after heavy rainfall or after
washing the vehicle, the braking effect may be delayed as the brake discs will be wet, or possibly
iced up (in winter). The brakes must be dried as quickly as possible by careful braking at higher
speed. Please ensure that no following vehicle and no other road user is put at risk as a result of this
action ⇒ .
A layer of salt that accumulates on the discs and pads will reduce the braking effect and increase the
braking distance. If the vehicle has not been braked for a long time on roads which have been gritted
with salt, the layer of salt must be reduced through careful braking ⇒ .
Corrosion on the brake discs and dirt in the brake pads are facilitated through long standstill times,
low mileage and low load levels. If the brake pads have been hardly used or if they are corroded,
Volkswagen recommends that the brake discs and brake pads be cleaned by braking strongly several
times from high speed. Please ensure that no following vehicle and no other road user is put at risk
as a result of this action ⇒ .
Brake servo
The brake servo will function only when the engine is running and reinforces the pressure applied by
the driver on the brake pedal.
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 ⇒ .

WARNING
Driving with worn brake pads or with a faulty brake system can cause accidents and serious injuries.
If the warning lamp lights up either alone or together with a text message in the instrument
cluster display, go to a qualified workshop immediately to have the brake pads checked and the
worn brake pads replaced.

WARNING
After driving through water, mud, slush etc., the brakes may react slowly and the braking distance
will be increased as the brake discs and pads will be wet, or possibly iced up in winter.
Dry and de-ice the brakes using careful braking manoeuvres. Make sure that you do not endanger
any other road users or violate any legal regulations when doing so.
Avoid abrupt and sudden braking manoeuvres directly after driving through water.

NOTICE
If you drive through water, parts of the vehicle, such as the engine, gearbox, running gear and
vehicle electrics, could sustain severe damage.
Never drive through salt water as salt can cause corrosion. Immediately rinse all components that
have been exposed to salt water with fresh water.
Running in the engine
A new engine has to be run in during the first 1,500 kilometres. This enables all the moving parts to
bed in together. During the first few operating hours, the engine has higher internal friction than it
does later.
Do not depress the accelerator fully.
Do not drive the vehicle at more than 2/3 of the maximum engine speed.

Gradually increase speed and engine speed.
The style of driving during the first 1,500 kilometres will also affect the engine quality. Even after this
time – and especially with a cold engine – drive the vehicle at moderate engine speeds in order to
reduce engine wear and to increase the mileage that the engine can cover.
Do not drive at engine speeds which are too low. Always shift down gear if the engine is not running
smoothly.
New tyres ⇒ Wheels and tyres  and brake pads ⇒ Notes on driving  must be run in carefully.

If the engine is run in gently, its life will be increased and its oil consumption reduced.
Using the vehicle in other countries and continents
The vehicle is produced at the factory specifically for a certain country and complies with this
country's registration regulations valid at the time of vehicle production.

Vehicles with ignition lock: turn the vehicle key to position ⇒ Fig. 99① . The ignition is
switched on.
Vehicles with a starter button: press the starter button once. The ignition is switched on.

been started. Move the gear lever to neutral position.
Vehicles with DSG dual clutch gearbox: move the selector lever to position P or N.
Vehicles with ignition lock: turn the vehicle key to position ⇒ Fig. 99②  – do not depress the
accelerator.
Release the vehicle key once the engine has started.
Vehicles with a starter button: press the starter button ⇒ Starter button  – do not depress the
accelerator. There must be a valid vehicle key in the vehicle before the engine can be started.
If the engine does not start immediately, switch off the starter and try again after about a minute.
Vehicles with starter button: perform an emergency start if necessary ⇒ No valid vehicle key
recognised .
Vehicles with starter button: the starter button is deactivated if the vehicle was locked with the
vehicle key. If you are in the vehicle and need to start the engine, unlock the vehicle first or perform
an emergency start ⇒ No valid vehicle key recognised .
Switch off the electronic parking brake if you wish to pull away.

WARNING
The risk of serious injury can be reduced with the engine running or when starting the engine.
Never start or run the engine in unventilated or enclosed spaces. The exhaust fumes contain carbon
monoxide, an odourless and colourless toxic gas. Carbon monoxide can cause people to lose
consciousness. It can also cause death.
Never start or run the engine if oil, fuel or any other highly flammable fluids are under or near the
vehicle, or are leaking out of the vehicle, e.g. as the result of damage.

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.

The instrument cluster shows the status of the start/stop system each time the button is pressed.
If the start/stop system has switched the engine off, it will start again as soon as the system is
deactivated manually with the button.
Always deactivate the start/stop system manually when driving through water.
Start/stop mode when Adaptive Cruise Control (ACC) is active
The engine will be switched off after the Adaptive Cruise Control (ACC) has brought the vehicle to a
standstill via an active braking intervention ⇒ Adaptive Cruise Control (ACC) .
The engine will be switched off after the Adaptive Cruise Control (ACC) has brought the vehicle to a
standstill via an active braking intervention ⇒ Adaptive Cruise Control (ACC) .
Vehicles with dual clutch gearbox DSG: when adaptive cruise control (ACC) is activated, the
dual clutch gearbox DSG® can switch to coasting mode.
Vehicles with dual clutch gearbox DSG: when adaptive cruise control (ACC) is activated, the
dual clutch gearbox DSG® can switch to coasting mode.
In the following instances, the engine will restart when the Adaptive Cruise Control (ACC) is active:
If the accelerator is depressed.
When the Adaptive Cruise Control (ACC) has resumed speed and distance control.
If the vehicle ahead has moved on.

WARNING
Never switch off the engine or the ignition 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. 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

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.
