engine VOLKSWAGEN T-ROC 2018 Owner's Guide

The cooling system functions only when the engine is running and at ambient temperatures above
+3

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.

The 12-volt vehicle battery will discharge if the auxiliary heating or ventilation is run several times
over an extended period. Drive the vehicle for an appropriate distance in between in order to
recharge the 12-volt vehicle battery.

The fuel gauge indication may not be accurate (just above the reserve quantity) when the vehicle is
parked on a slope; this may restrict the function of the auxiliary heater.

The auxiliary heater may switch on automatically when the engine is started at temperatures below
+5

NOTICE
Free access to the pedals must be ensured at all times. For example, a larger brake pedal travel will
be necessary in order to stop the vehicle if a brake circuit fails. The brake pedal will have to be
depressed further and harder than normal.

Recommended gear.
Depending on the vehicle's equipment level, the instrument cluster display may indicate a gear
which should be selected to reduce fuel consumption while the vehicle is in motion.
Vehicles with DSG dual clutch gearbox: the selector lever must be in the Tiptronic position for
this Changing gear using Tiptronic
No recommended gear is indicated if the most suitable gear is already selected. The currently
selected gear is displayed.
Information on cleaning the particulate filter
The engine management system recognises when the particulate filter is becoming saturated and
supports regeneration of the filter by recommending the most suitable gear when driving. Compared
with normal driving, this may mean driving with an increased engine speed Particulate filter

CAUTION
The gear-change indicator is designed only to assist the driver and cannot replace the driver's own
judgement.
The driver has full responsibility for selecting the correct gear in all situations, e.g. when overtaking
or when driving up and down hills.

Driving in the correct gear can help to reduce fuel consumption.

file Driving profile selection and 4MOTION Active Control
Avoid driving at full throttle
Never drive the vehicle at its top speed. The drag coefficient increases at excessively high speeds.
This in turn increases the force needed to move the vehicle.
Reduce idling
Pull away immediately with low engine speeds. If you are stopped for a long period, do not allow the
engine to idle but switch it off, e.g. when in a traffic jam or at a railway crossing.
In vehicles with an activated start/stop system, the engine can switch off automatically when the
vehicle is stopping and when the vehicle is stationary Start/stop system
Refuel moderately
A full fuel tank increases the weight of the vehicle. A fuel tank that is half or two thirds of the way
full is sufficient for journeys in urban traffic in particular.
Avoid short journeys
A cold engine has very high fuel consumption. The optimum operating temperature is reached only
after driving a few kilometres. The fuel consumption is above average at very low ambient
temperatures, e.g. in winter Fig. 97
Carry out regular maintenance
Regular maintenance is an essential prerequisite for economical driving and increases the service life
of the vehicle.
Observe the tyre pressures
Low tyre pressures does not just mean greater wear, but also increase the rolling resistance of the
tyres and thus the fuel consumption. Use optimised rolling resistance tyres.
Adjust the tyre pressure according to the load. Observe the information on the tyre pressure sticker
Useful information about wheels and tyres
Tyre Pressure Loss Indicator or Tyre Pressure Monitoring System Tyre monitoring system
Use low viscosity engine oils
Fully synthetic engine oils with a low viscosity decrease frictional resistance in the engine and are
distributed better and more quickly, especially during cold starts.
Do not drive with unnecessary loads in the vehicle
You can reduce fuel consumption by clearing out the luggage compartment before setting off, for
example by removing empty drink crates or unused child seats.
To keep the vehicle's air resistance as low as possible, remove any add-on parts and equipment such
as ski racks, bicycle racks and roof carriers once you have finished using them.
Save electrical energy

riven by the engine and generates electrical power for convenience consumers
such as the air conditioning system, windscreen heating and ventilation. Saving electrical energy is
easy, e.g.:
Open the windows and doors before driving at high outside temperatures and drive for a short
distance with a window open. Only then switch the air conditioning system on.
Switch the convenience consumers off as soon as they have served their purpose.

WARNING
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic
conditions.

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
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
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.

move unpredictably.
Any objects protruding from the luggage compartment must be marked to ensure that they are
visible to other road users. Comply with legal regulations.
If items protrude out of the luggage compartment, never use the boot lid to wedge them into place
or hold them in position.
If you have to drive with the boot lid open, you must remove any carriers and the loads attached to
them from the boot lid.

WARNING
Poisonous exhaust fumes could enter the vehicle interior when the boot lid is open. This could result
in loss of consciousness, carbon monoxide poisoning, serious injury and accidents.
You should always drive with the boot lid closed in order to prevent poisonous exhaust fumes from
entering the vehicle.
If exceptional circumstances require you to drive with an open boot lid, you must do the following to
reduce the amount of poisonous exhaust fumes that could enter into the vehicle:
Close all windows and the glass roof.
Switch off the air recirculation mode of the heating and fresh air system or air conditioning system.
Open all vents in the dash panel.
Switch the blower for the heating and fresh air system or for the air conditioning system to the
highest setting.

NOTICE
The vehicle height, and possibly the length, are different when the boot lid is open.
Driving through water
Please follow these points in order to prevent damage to your vehicle when driving through water,
for example on flooded streets:
Check how deep the water is before driving through it. The water may be no higher than the lower
edge of the body
Do not drive faster than walking speed.
Never stop the vehicle, reverse or switch off the engine while in water.
Oncoming vehicles will create waves that could increase the water level for your vehicle to such an
extent that it is not safe to drive through the water.
Always deactivate the start/stop system manually when driving through water Start/stop system

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 tyresand brake pads Notes on drivingmust 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.
