2014 VOLKSWAGEN JETTA GLI air condition

Brake system malfunction
If you brake and find that the vehicle doesn't brake nearly as well as it used to (sudden increase in stopping distance), a brake circuit may have failed. The brake warning light h or BRAKE will come on and a message may appear in the instrument cluster display. If you believe the vehicle is safe to drive, immediately take it to the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for repair. Drive slowly and very carefully, allow for the longer stopping distance, and be ready to push longer and harder on the brake pedal to slow the vehicle down.
Brake booster
The brake booster works only when the engine is running. It increases the force on the brakes above and beyond the pressure put on the brake pedal by the driver.
If the brake booster is not working, or if the vehicle has to be towed, you will have to push the brake pedal harder to make up for the lack of booster assistance and the resulting longer stopping distance
⇒ .
WARNING
New brake pads do not provide maximum braking performance.
x New brake pads do not have the best stopping power for the first 200 miles (320 km) and must be “broken in.” You can compensate for the slightly reduced braking force by putting more pressure on the brake pedal.
x Drive with extra care while the new brake pads are being broken in. This reduces the risk of collisions and serious personal injuries due to a loss of control over the vehicle.
x Never follow other vehicles too closely or put yourself into other situations that might require sudden, hard braking, especially when the brake pads have not been broken in.
WARNING
Overheated brakes will reduce the vehicle's stopping power and increase stopping distances considerably.
x When driving downhill, the brakes have to work especially hard and heat up quickly.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and shift into lower gear (manual or automatic transmission). This will let the vehicle use engine braking and reduce the load on the brakes. Otherwise, the brake system could overheat and possibly fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
x A damaged front spoiler or a non-standard spoiler can reduce airflow to the brakes and make them overheat.
WARNING
Wet brakes or brakes coated with ice or road salt react slower and need longer stopping distances.
x Carefully apply the brakes to test them.
x Always dry brakes and clean off ice and salt coatings with a few cautious brake applications when visibility, weather, road and traffic conditions permit.

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 system 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.
x Towing a trailer.
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.

Heating and air conditioning

WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious personal 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, collisions 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 recommends 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 system can leave residue on the evaporator and on the dust and pollen active carbon filter, resulting 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 !

The air conditioner is most efficient when the windows and the power sunroof are closed. If the vehicle is stationary and the passenger compartment becomes very hot due to sunlight, briefly opening the windows and the power sunroof may speed up the cooling process.
Keep the air intake slots in front of the windshield free of ice, snow, and leaves so that the heating and ventilation systems can work properly.
Settings for optimum visibility
When you switch on the cooling system, both the temperature and humidity in the vehicle are reduced. This will help make passengers feel more comfortable and help keep the windows from fogging up.
For manual A/C
x Switch off the air recirculation, Air recirculation.
x Set the fan to the desired speed.
x Turn the temperature knob to the center position.
x Open and adjust all air vents in the instrument panel ⇒ page 297, Air vents.
x Turn the air distribution knob to the desired setting.
x Push the!

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.
Air vents

WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents, collisions and serious personal injury.
x Never use air recirculation mode over an extended period of time, since no fresh air will enter the passenger compartment.
x 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.
NOTICE
Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation system can leave residue on the evaporator and on the dust and pollen active carbon filter, resulting in permanent odors whenever the air conditioner is switched on.
Climatronic: When backing up and while the automatic wiper/washer is operating, air recirculation is briefly activated to help keep exhaust fumes from getting into the passenger compartment.

If you have questions regarding the care and cleaning of the leather upholstery in the vehicle, please contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Care and treatment
Natural leather requires special attention and care. Napa leather has a smooth surface. The intensity of the color application determines the leather's appearance and texture. If you can see the leather grain and other natural characteristics, this is an untreated napa leather that will provide very comfortable seating. Delicate veins, closed scars, insect bites, folds, and a slightly clouded color remain visible and represent authentic characteristics of the natural material. Untreated napa leather has no protective coating. It is therefore more susceptible to damage. You should keep this in mind if the leather is going to be exposed to severe wear from children, animals, or other factors. By contrast, leather that has a protective coating is more robust. This has a positive effect on the leather's durability in daily use. The typical natural characteristics are hardly visible or no longer visible at all, but that has no impact on the quality of the leather itself. The typical characteristics of untreated leather are much more distinctive than those of a surface-treated leather.
x After each cleaning, apply cream that waterproofs the leather and protects it against the sun. Such creams also nourish the leather, let it breathe, keep it flexible and moisturized. At the same time it protects the surface.
x Clean leather every 2 to 3 months and remove any new stains.
x Treat leather with a suitable leather-care product twice a year ⇒ .
x Apply cleaning and conditioning materials sparingly and always with a dry, lint-free cotton or wool cloth. Do not apply cleaning and conditioning materials directly to the leather.
x Remove fresh stains such as ballpoint pen, lipstick, ink, shoe polish, etc. as soon as possible.
x Preserve the leather's color. If necessary, refresh fading spots with a specially-colored leather cream.
x Wipe the leather with a soft cloth.
Cleaning
Volkswagen recommends using a slightly moistened cotton or wool cloth for general cleaning.
It is important not to let water soak through the leather or penetrate into seams.
Before cleaning leather surfaces, read and heed the information Cleaning upholstery on heated seats and power seats or seats with airbag components.
