2021 VOLKSWAGEN T-ROC check engine

The cooling system cannot be switched on or its function is restricted
The cooling system functions only when the engine is running and at ambient temperatures above
+3°C (+38°F).
The cooling system is switched off when the engine is very warm.
Switch on the blower.
Check the fuse of the air conditioning system ⇒ Fuses in the dash panel .
Change the dust and pollen filter ⇒ Service .
If the fault persists, seek expert assistance.
The heating and fresh air system cannot be switched on or its function is restricted
The heating and defrost function are more effective when the engine is warm.
If the fault persists, seek expert assistance.
Condensation on the windows
Keep the air intake in front of the windscreen free of ice, snow or leaves in order to improve heating
and cooling performance ⇒ Vehicle care .
Do not cover the air vents in the rear of the luggage compartment to allow air to flow through the
vehicle from the front to the rear.
Press the button or turn the rotary knob to position in order to switch on the defrost
function ⇒ .
The wrong unit of temperature is set
Change the unit of temperature for all temperature displays in the vehicle using the Infotainment
system ⇒ Infotainment system controls and displays .
Change the unit of temperature in the instrument cluster menu ⇒ Instrument cluster .
Water under the vehicle
If the humidity and temperature outside the vehicle are high, condensation can drip off the
evaporator of the cooling system and form a pool underneath the vehicle. This is normal and does
not indicate a leak!
If the outside humidity is high and the outside temperature low, condensation may evaporate when
the auxiliary heater is running ⇒ Auxiliary heater and ventilation . If this is the case, steam may
appear underneath the vehicle. This is not a sign that the vehicle is damaged.

WARNING
Poor visibility through all windows increases the risk of collisions and accidents, which can cause
serious injuries.

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.

Avoid any abrupt or sudden driving and braking manoeuvres as this could cause the open boot lid to
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 .

Emergency programme
There is a fault in the system if all the displays on the instrument cluster for the selector lever
positions have a light background. The DSG® dual clutch gearbox is running in an emergency
programme. The vehicle can still be driven in the emergency programme, but only at reduced speed
and not in all gears.
In vehicles with a DSG® dual clutch gearbox, you may no longer be able to select reverse gear.
In all cases, you should have the DSG® dual clutch gearbox checked by a qualified workshop
immediately.
Vehicle does not move even though position is engaged
If the vehicle will not move in the required direction, the system may have selected the position
incorrectly.
Depress the brake pedal and reselect the position.
If the vehicle still does not move in the required direction, there is a system fault. Seek expert
assistance and have the system checked.

WARNING
Never move the selector lever out of the position P if the electronic parking brake is not switched on.
Otherwise the vehicle could move unexpectedly if it is stopped on an uphill or downhill gradient,
which could lead to accidents and serious injuries.

NOTICE
