WARNING
Unsecured or incorrectly stowed items can fly through the vehicle, causing serious personal injury during hard braking or sharp steering or in an accident. Loose items can also be struck and thrown through the passenger compartment by the front airbags if they inflate. To help reduce the risk of serious personal injury:
x Always stow all objects securely in the vehicle. Always put luggage and heavy items in the luggage compartment.
x Always secure objects in the passenger compartment properly with suitable straps so that they cannot move into the deployment zone of a side or front airbag during sudden braking, in a sudden maneuver, or in a collision.
x Always keep storage compartments closed while driving.
x Never stow hard, heavy, or sharp objects in the vehicle's open storage compartments, on the shelf behind the rear seat bench, or on the top of the instrument panel.
x Always remove hard, heavy, or sharp objects from clothing and bags in the vehicle interi-or and stow them securely in the luggage compartment.
WARNING
Transporting heavy objects causes the handling characteristics of the vehicle to change and increases braking distances. Heavy loads which are not properly stowed or secured in the vehicle can lead to a loss of vehicle control and cause serious personal injury.
x Transporting heavy items causes the handling characteristics of the vehicle to change by shifting the vehicle's center of gravity.
x Always distribute luggage evenly and as low as possible within the vehicle. The vehicle capacity weight figures apply when the load is distributed evenly in the vehicle (passengers and luggage).
x Always stow luggage and heavy items in the luggage compartment as far forward of the rear axle as possible and secure them with appropriate straps to the tie-downs provided.
x Never exceed the vehicle's Gross Vehicle Weight Rating or Gross Axle Weight Ratings, which are printed on the Safety Compliance Certification Label located on the door jamb of the driver door. Exceeding the permissible weight can cause the vehicle to skid and behave differently.
x Always adapt your speed and driving style to accommodate your payload and its weight distribution within your vehicle.
x Be especially cautious and gentle when stepping on the accelerator pedal and avoid sud-den braking and other maneuvers.
x Brake earlier than you would if you were not driving a loaded vehicle.
NOTICE
The defroster heating wires or antenna in the rear window can be damaged by objects that rub against them.
The ventilation slots between the rear window and the luggage compartment cover must not be blocked so that stale air can escape from the vehicle.

NOTICE
x The defroster heating wires or antenna in the rear window can be damaged by hard or sharp things on the shelf below the rear window.
x Do not keep any food, medicine, or other items sensitive to heat or cold in the vehicle. They can be damaged or made unusable by heat or cold.
x Things that are made of transparent materials (such as eyeglasses, magnifying glasses, or transparent suction cups on the windows) can magnify sunlight and damage the vehicle.
The ventilation slots between the rear window and the luggage compartment cover must not be blocked so that stale air can escape from the vehicle.

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 controlcan 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 climate control system has to produce starkly con-trasting 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 tempera-ture. 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.

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 heating and ventilation systems 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 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 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 A/C button. The indicator light in the button must come on.
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.
Keep the air intake slots in front of the windshield free of ice, snow and leaves in order to main-tain proper functioning of the heating and ventilation systems.
Maximum heating output and defrosting performance are not possible until the engine has reached operating temperature.

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.

Removing snow
Remove snow from all windows and outside mirrors with an appropriate brush.
Removing ice
The best way to remove ice is with a deicer spray. When using an ice scraper always scrape in one direction, never back and forth. Dirt can scratch the glass when moving the scraper backward.
WARNING
Dirty or fogged up windows reduce visibility and increase the risk of accidents and severe injuries.
x Don't drive until you have clear visibility through all windows.
x Remove ice, snow and condensation from all inside and outside window surfaces.
NOTICE
x Never mix recommended cleaning agents with other cleaning agents in the windshield washer reservoir. If you do, this could cause sediments or other by-products that can clog the windshield wiper nozzles.
x Never use warm or hot water to remove snow and ice from windows and mirrors. This could cause the glass to crack!
x The heating elements for the rear defroster are on the inside of the rear window. Do not put stickers over the heating elements on the inside of the rear window and never clean the inside of the windows with corrosive or acidic cleaning agents or other chemicals that could damage the heating elements.
x Antennas installed on the insides of windows can be damaged by abrasive objects or by corrosive or acidic cleaning agents or other chemicals. Do not place any stickers on the wind-shield-integrated antenna and never clean the antenna with corrosive or acidic cleaning agents or other chemicals.

Starting the engine
x Start the engine of the vehicle with the good battery that is providing help and let it run at idle speed.
x Turn on the ignition of the vehicle with the dead battery. If the engine starts, wait 2 to 3 minutes
until it “runs smoothly” before removing the jumper cables as described below ⇒ . If the engine does not start within about 10 seconds, turn off the ignition and wait at least 1 minute; then try again.
Before removing the jumper cables
(1) Switch off the headlights (if they are on).
(2) In the vehicle with the dead battery, switch on the heater fan and the rear window defroster. This helps to minimize voltage spikes when the cables are disconnected.
Removing the jumper cables
With the engine running, remove the jumper cables in reverse order to the way they were connected.
(1) Disconnect the black (-) cable from the vehicle with the dead battery.
(2) Disconnect the black (-) cable from the other vehicle (vehicle with the good battery).
(3) Disconnect the red (+) cable from the other vehicle (vehicle with the good battery).
(4) Disconnect the red (+) cable from the vehicle with the dead battery.
(5) Close the battery cover or snap shut the cap on the positive jump-start terminal8, as the case may be.
