1. Bring the vehicle to a complete stop ⇒ .
2. Depress and hold down the brake pedal until step 4 is completed.
3. Automatic transmission: Shift the transmission into Park (P).
4. Apply the parking brake to help prevent the vehicle from moving
5. Turn the vehicle key to position ⇒ fig. 111 (0) in the ignition switch. Briefly press the starter button ⇒ fig. 112. If the engine will not switch off, carry out the emergency shut-off procedure ..
6. Manual transmission: Shift into 1st gear (vehicle on flat surface or pointing uphill) or reverse (vehicle pointing downhill).
7. Removing the vehicle key from the ignition switches off electrical equipment and activates the steering column lock.
Opening the doors switches off electrical equipment and activates the steering column lock.
WARNING
Never stop the engine before the vehicle has come to a complete stop. You can lose control of the vehicle, crash, and be seriously injured.
x The airbags and safety belt pretensioners will not work when the ignition is switched off.
x The brake booster does not work when the engine is not running. More brake pedal pressure will be needed to stop the vehicle.
x The power steering system does not work when the engine is not running, and you will need more force to steer the vehicle.
x When the key is removed from the ignition switch, the steering will lock and you will not be able to steer the vehicle.
NOTICE
If the vehicle has been driven hard for a long time, the engine could overheat when it is stopped. To reduce the risk of engine damage, let the engine idle in Neutral for about 2 minutes before you switch off the ignition.
If the ignition is switched on or the engine is running and the driver door is opened, a chime sounds. The chime is also a reminder to switch off the engine and turn off the ignition before leaving and locking the vehicle from the outside.
On vehicles with automatic transmissions, the vehicle key can only be removed from the ignition when the transmission is in Park (P).
After the engine has been switched off, the radiator fan in the engine compartment may keep running for several minutes, or may start running after the vehicle has been parked for a while, even if the ignition is switched off and the vehicle key has been removed. The radiator fan shuts off automatically when the engine has cooled down enough.

Connecting the engine preheating system
x Use only the provided connecting cable, together with an appropriate extension cable if necessary.
x All cables and adapters that are used must not be damaged ⇒ .
x Open the cover ⇒ fig. 114 (1).
x Plug the connecting cable into the socket (2).
x Attach the connecting cable to an extension cable if necessary. Always use a 12 gauge or heavier heavy-duty extension cable that can be properly grounded to a three-prong Ground Fault Circuit (GFI) wall outlet and is not longer than 100 ft (30 meters).
x Plug the connecting cable or the extension cable into a 120 Volt Ground Fault Circuit (GFI) wall outlet that is properly protected against rain and other moisture. Never plug the preheater into a normal outlet regardless of whether the outlet is grounded or not.
x Always disconnect the connecting cable and close the cover (1) before starting the engine.
WARNING
Improper use of the engine preheating system may cause short circuits, fires, and serious or fatal personal injuries.
x Always connect the connecting cable to a 120 Volt Ground Fault Circuit (GFI) wall outlet. The outlet must be protected from water, moisture and other fluids.
x Never connect the engine preheating system to a conventional socket, regardless of whether the socket is protected or not.
WARNING
Using an outlet or power cables that are incorrect or damaged, using electrical appliances incorrectly, or ignoring safety precautions can result in short circuits, accidents, injuries, and life-threatening electrical shocks.
x Never use a damaged outlet or a damaged power cable.
x Always plug the preheating system into a 120 Volt Ground Fault Circuit (GFI) wall outlet that is properly protected against rain and other moisture.
x Always check the fuse protection of the 120 Volt power source before using the connecting cable.
x Always use a 12 gauge or heavier heavy-duty extension cable that can be properly grounded to a three-prong GFI outlet. The extension cable must not be longer than 100 ft (30 meters).
x Check the cables for damage before every use. Never use a damaged cable. Damaged cables must be replaced. See an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
x Only use the cables provided.
x Always remove the connecting cable before starting the engine.
x Never attempt to alter or repair cables or other electrical components.
x Never let plugs or connectors come into contact with water, moisture, or any other fluids.
If the engine preheating system is used occasionally, test the GFI circuit breaker (Ground Fault Circuit Interrupter) once a month. Test it once a week if the system is used regularly.

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.

Changing brake fluid
Brake fluid must be changed according to the service schedule in your ⇒ booklet Warranty and
Maintenance. Have the brake fluid checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Refill only with new brake fluid that meets the standards listed above.
WARNING
Brake failure and reduced brake performance can be caused by not having enough brake fluid in the reservoir or by old or incorrect brake fluid.
x Check the brake system and brake fluid level regularly.
x Always change the brake fluid according to the service schedule in your
⇒ booklet Warranty and Maintenance.
x Hard braking with old brake fluid may cause vapor lock. Vapor lock reduces braking performance, increases stopping distances and can even cause total brake failure.
x Always make sure that only the correct brake fluid is used. Only use brake fluid that expressly conforms to VW Standard 501 14 or, if it is not available, only use a high-quality brake fluid that conforms to U.S. Standard FMVSS 116 DOT 4 requirements.
x Using another brake fluid, or one that is not of high quality, can impair the function of the brake system and reduce its effectiveness. If the container does not say that the brake fluid complies with VW Standard 501 14, or U.S. Standard FMVSS 116 DOT 4, do not use it.
x The brake fluid must be new.
WARNING
Brake fluid is poisonous.
x To reduce the risk of poisoning, never use food, beverage or other non-original containers to store brake fluid. Someone might be misled by the original label on the container, or by the shape of the container, and drink the brake fluid. This could occur even if you relabel the container as “brake fluid.”
x Only store brake fluid in the closed, original container and keep it out of the reach of children.
NOTICE
Brake fluid will damage vehicle paint, plastic parts, and tires. Wipe any brake fluid off vehicle paint and other vehicle parts immediately.
Brake fluid can pollute the environment. Brake fluid that has leaked out must be collected and disposed of properly, following all applicable environmental regulations.

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 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
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 !
