Check coolant VOLKSWAGEN PASSAT 2015 B8 / 6.G Owners Manual

Air conditioner does not work
The air conditioner may not switch on for one of the following reasons:
x The engine is not running.
x The fan is switched off.
x The air conditioner fuse has blown.
x The outside air temperature is colder than about +38 °F (+3 °C).
x The air conditioner compressor has been temporarily switched off due to excessive engine coolant temperature.
x There is another malfunction in the vehicle. Have the air conditioner checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Special considerations
When it is very hot and humid outside, water condensation can drip from the air conditioner evapora-tor and form a puddle under the vehicle. This is normal and does not indicate a leak.
The climate control system adjusts the passenger compartment temperature as fast as possible considering the outside temperature.
Due to residual moisture in the air conditioner, the windshield may fog up after the engine is started. Switch on the windshield defroster to help evaporate the condensation as quickly as possible.
The air coming out of the vents flows through the passenger compartment and through the vents under the rear window. Do not cover these slots with clothing or other things.

Possible cause Proper response
(B) Normal range Engine coolant level too low.
Check the engine coolant level after the engine has cooled down and add engine coolant if low. If the engine coolant level is correct or the problem continues after adding coolant, do not drive any farther. Contact an author-ized Volkswagen dealer or authorized Volkswagen Service Facility. These instructions apply only when the coolant temperature stays in the normal range. Stop immediately if the needle goes into the red warning zone (C).
– Engine coolant system malfunction.

Checking engine coolant level and topping off

x Refill engine coolant only up to the top edge of the marked fill range ⇒ fig. 186. Excess engine coolant may be forced out of the engine cooling system when it gets hot and cause damage.
x In the case of significant engine coolant loss, refill engine coolant only when the engine is completely cooled down. Significant engine coolant loss is a sign of leaks in the cooling sys-tem. Have the engine cooling system checked immediately by an authorized Volkswagen deal-er or an authorized Volkswagen Service Facility. Otherwise the engine may be damaged!
x When changing or topping off operating fluids, make sure that you pour the fluids into the correct reservoirs. Serious malfunctions and engine damage can result if you pour operating fluids into the wrong reservoir.
