Plenum chamber
The plenum chamber is located in the engine compartment between windshield and engine, under a perforated cover. Outside air is taken into the vehicle interior from the plenum chamber via the climate control system.
Regularly remove leaves and other loose objects from the plenum chamber cover by hand or with a vacuum cleaner.
WARNING
Injuries, scalding, electric shock, accidents and fire hazards can occur while working on the engine or in the engine compartment!
x Before working in the engine compartment, be sure to familiarize yourself with the
necessary procedures and generally accepted safety precautions ⇒ Working in the engine compartment.
x Volkswagen recommends having the work performed by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
NOTICE
Spraying or pouring water (e.g. with power washer) into the plenum chamber can cause severe damage to the vehicle.
Wash the engine compartment only in special wash bays so that the oily dirt and fuel residue that are washed off the vehicle will not enter the sewage system. In some areas it illegal to wash the engine compartment anywhere other than at such specified locations.

x Accessories and other things installed in front of the cooling air intakes impair the efficiency of the engine coolant. The engine can overheat under high ambient temperatures or under high engine loads!
Leaking operating fluids can pollute the environment. Collect leaking operating fluids in suitable containers and dispose of them properly in accordance with applicable environmental laws and regulations.

WARNING
Improperly lifting your vehicle with a workshop hoist or floor jack can cause the vehicle to fall off the hoist or jack and cause serious personal injury.
x Always read and heed the operating instructions from the floor jack manufacturer and legal regulations if necessary before using the floor jack to lift the vehicle.
x Never let anyone stay in the vehicle when it is being lifted or when it is off the ground.
x Always lift your vehicle only at the designated lift points shown in the illustrations
⇒ fig. 308 and ⇒ fig. 309. Not using the designated lift points can cause the vehicle to fall off the floor jack when heavy parts such as the engine or transmission are removed.
x Always make sure that the vehicle's lift points lie as flat as possible and centered on the carrier plates of the floor jack.
x Never start the engine when you have raised the vehicle on the floor jack. The engine vibrations and vehicle movements could knock the vehicle off the floor jack.
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle is safely supported on safety stands intended for that purpose that are strong enough to support the weight of the vehicle.
x Never use the floor jack as a ladder or step ladder.
x Always make sure that the weight of the vehicle is not heavier than the lifting capacity of the floor jack and safety stands being used.
NOTICE
x To help prevent serious vehicle damage, never lift the vehicle by the engine oil pan, transmission housing, or by the front or rear axles or suspension.
x To help prevent damage to the underbody or chassis, always insert a rubber pad between the hoist and the lifting points. In addition make sure the lifting arms have enough clearance.
x The lifting arms should not touch side sills or other parts of the vehicle.
