2015 VOLKSWAGEN BEETLE climate control

Driving with an open rear hatch can lead to serious personal injury. If you have to drive with an open rear hatch, make sure that all objects and the hatch itself are properly secured and take appropriate measures to keep toxic exhaust fumes from entering the vehicle.
WARNING
Driving with an unlatched or open rear hatch can lead to serious personal injury.
x Never transport objects larger than those that fit completely in the luggage compartment, because the rear hatch cannot be fully closed properly.
x After closing the rear hatch, always pull up on it to make sure that it is properly closed and cannot open suddenly when the vehicle is moving.
x Always stow all objects securely in the luggage compartment. Loose objects can fall out of the luggage compartment and injure others on the road behind you.
x Drive carefully; anticipate what other drivers will do.
x Avoid abrupt or sudden acceleration, steering, or braking, because the unlatched rear hatch can move suddenly.
x Always mark objects sticking out from the luggage compartment clearly for others to see. Obey all applicable legal requirements.
x Never use the rear hatch to “clamp” or “hold” objects that stick out of the luggage com-partment.
x Always remove any luggage rack or other rack mounted on the rear hatch (along with any luggage on the rack) before driving with an open rear hatch.
WARNING
Driving with an open rear hatch can cause poisonous carbon monoxide in the engine exhaust to get into the passenger compartment.
x Carbon monoxide causes drowsiness, inattentiveness, poisoning, and loss of conscious-ness. It can lead to accidents and severe personal injuries.
x Always keep the rear hatch closed while driving to help keep poisonous exhaust fumes from being drawn into the vehicle.
x Never transport objects that are too large to fit completely into the luggage area, because then the rear hatch cannot be fully closed.
x If you absolutely must drive with an open rear hatch, do the following to reduce the risk of carbon monoxide poisoning:
– Close all windows and the power sunroof.
– Switch off the climate control system's air recirculation feature.
– Open all air vents in the instrument panel.
– Set the fresh air fan to the highest speed.
NOTICE
The open rear hatch changes the vehicle length and height.
Driving a loaded vehicle

Defensive driving and “flowing” with traffic
Frequent braking and acceleration increase fuel consumption significantly. Just by driving defensively and keeping a sufficiently large distance away from the vehicle in front of you can make up for the speed fluctuations caused by taking your foot off the accelerator. Active braking and accelerating is then not necessarily required.
Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical than constantly accelerating and braking. Usually you can reach your destination just as quickly by driving at a moderate, but steady speed.
The cruise control can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the air conditioner has to produce starkly contrasting temperatures, it requires a large amount of energy, which is generated by the engine. The temperature in the vehicle should therefore not be extremely different from that of the outside temperature. It may be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not running. The transmission will not be lubricated and will be damaged.

WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious person-al injuries.
x Always make sure all windows are clear of ice, snow and condensation for good visibility to the front, sides, and rear.
x Maximum heating output and defrosting performance are not possible until the engine has reached operating temperature. Wait until you have good visibility before driving off.
x Always make sure you know how to properly use the climate control system as well as the rear window defroster that you will need for good visibility.
x Never use air recirculation for long periods of time. When the air conditioner is off and recirculation mode is on, condensation can quickly form on the windows and greatly reduce visibility.
x Always switch off recirculation mode when it is not needed.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents, colli-sions and serious personal injury.
x Never switch off the fan for a long period of time and never use air recirculation for a long period of time because no fresh air will enter the passenger compartment.
NOTICE
x If you think the air conditioner is not working properly or may be damaged, switch it off to help prevent more damage. Have the air conditioner checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
x Air conditioner repair requires specialized knowledge and special tools. Volkswagen rec-ommends that you see an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
x Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation sys-tem can leave residue on the evaporator and on the dust and pollen active carbon filter, result-ing in permanent odors whenever the air conditioner is switched on.
If the air conditioner is switched off, the fresh outside air will not be dehumidified. To help keep the windows from fogging over, Volkswagen recommends leaving the air conditioner (compressor) switched on. Press the !

Special considerations
When it is very hot and humid outside, water condensation can drip from the air conditioner evaporator 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 in the luggage compartment. Do not cover these slots with clothing or other things.
Air vents

Fig. 134 In the instrument panel: Air vents.

If necessary, the engine compartment should be cleaned by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Incorrect cleaning procedures could remove corrosion protection and damage electrical components, among other things. In addition, water could enter
directly into the vehicle interior through the plenum chamber ⇒ .
Never use a power washer to clean the engine compartment ⇒ .
If the engine compartment is extremely dirty, have it cleaned professionally by your authorized Volkswagen dealer or authorized Volkswagen Service Facility.
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 (for example, with a 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.
