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. 325 and ⇒ fig. 326. 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, trans-mission 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.

Checklist
For your own safety and that of your passengers, carry out the following steps in the order listed ⇒ :
1. Park the vehicle at safe distance from traffic and on a suitable surface ⇒ .
2. Switch on emergency flashers by pressing the  switch ⇒ fig. 327.
3. Apply the electronic parking brake to help prevent the vehicle from moving.
4. Shift the transmission into Park (P)
5. Stop the engine and remove the key from the ignition switch
6. Have all passengers exit and go to a safe location away from moving traffic, such as behind a guard rail.
7. Take all vehicle keys with you when leaving your vehicle.
8. Set up a warning triangle or other warning device in order to alert other motorists and cyclists.
9. Let the engine cool down and get expert assistance if necessary.
If the emergency flashers are on, use the turn signal lever to indicate a direction or lane change, for example when the vehicle is being towed. This temporarily interrupts the emergency flashers.
Switch on the emergency flashers when:
x Traffic suddenly slows down or stops in front of you to warn those approaching from behind.
x In any emergency situation.
x If the vehicle breaks down.
x When being towed.
Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to alert other motorists and cyclists to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common sense.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot and can cause a fire and serious personal injury.
x Never park where parts of the hot exhaust system or catalytic converter could ignite flammable materials, such as dry grass, brush, leaves, spilled fuel, etc.
The vehicle battery will be drained if the emergency flashers are on for a long time – even if the ignition is switched off.

WARNING
Using the tire mobility set on the side of the road can be dangerous. To help reduce the risk of serious personal injury:
x Always stop the vehicle as soon as it is safe to do so and move the vehicle a safe distance off the road where it is safe to use the tire mobility set.
x Make sure that the ground is level and firm.
x All passengers and especially children must stay a safe distance away from you while you are working and keep out of the area you are working in.
x Turn on the emergency flasher and set up another warning device about 25 yards (25 meters) behind the vehicle to warn approaching traffic.
x Use the tire mobility set only if you are familiar with the necessary steps. Otherwise, get expert assistance.
x Use the tire mobility set only in emergencies and only until you can get professional help.
x Immediately replace a tire repaired with the tire mobility set.
x Sealant is harmful and must immediately be removed in case of skin contact.
x Always store the tire mobility set out of reach of children.
x Never use a vehicle jack, even if the jack is approved for use with your vehicle.
x Always switch off the engine, engage the electronic parking brake, and shift the transmis-sion into Park (P) to reduce the risk that the vehicle will move unexpectedly.
WARNING
Improper use of the tire mobility set can cause a temporary tire to fail and lead to loss of vehicle control and serious personal injuries.
x Always remember that a tire filled with sealant does not handle as well as an undamaged tire without sealant.
x Never drive faster than 50 mph (80 km/h) with a sealed tire.
x Never use the tire mobility set if the outside temperature is below –4 °F (–20 °C).
x Never drive with a tire that has cuts or punctures, especially when they are larger than 3/16 in (4 mm).
x Use the tire mobility set only for emergencies until you can get professional help.
x If the tire cannot be inflated to at least 36 psi (2.5 bar), do not drive the vehicle. Contact the nearest authorized Volkswagen dealer, authorized Volkswagen Service Facility, or other qual-ified workshop.
x If the tire inflation pressure drops below 26 psi (1.8 bar) after driving for 10 minutes, do not drive the vehicle any farther. Contact the nearest authorized Volkswagen dealer, author-ized Volkswagen Service Facility, or other qualified workshop.
x Always replace a tire repaired with the tire mobility set immediately. Do not drive a tire that has been repaired with the tire mobility set longer or farther than is absolutely necessary.
x Avoid full throttle acceleration, hard, braking, and fast cornering.
x Drive at slow speed for 10 minutes. Then get out and check the air pressure and condition of the sealed tire.
Obey all legal requirements when disposing of used or expired sealant.
New tire inflation cylinders are available from authorized Volkswagen dealers and authorized Volkswagen Service Facilities.

Inflating the tire
x Screw the tire inflation hose ⇒ fig. 343 (5) of the air compressor tightly to the tire valve.
x Check whether the air release valve ⇒ fig. 343 (7) is screwed on tightly.
x Open the engine hood ⇒  Working in the engine compartment.
x Attach the cable clips ⇒ fig. 343 (9) only to the jump-start terminals in the engine compartment
⇒ fig. 344. The red clip on the compressor cable is connected to the positive (+) terminal; the black clip is connected to the negative terminal (—).
x Start the vehicle engine and let it run.
x Switch the air compressor on using the ON / OFF switch ⇒ fig. 343 (8),
x Let the air compressor run until a pressure of 36 – 44 psi (250 - 300 kPa) is reached ⇒ . Maxi-
mum run time 8 minutes ⇒ .
x Switch off the air compressor.
x If an air pressure of 36 – 44 psi (250 - 300 kPa) cannot be reached, unscrew the tire inflation hose from the tire valve.
x Drive about 30 feet (10 meters) backwards or forwards so that the sealant can be distributed inside the tire.
x Connect the tire inflation hose of the air compressor again to the tire valve and repeat the inflation process.
x If the required tire pressure still cannot be reached, the tire is too badly damaged. The tire cannot
be sealed using the tire mobility set. Do not drive the vehicle. Get professional assistance ⇒ .
x Disconnect the air compressor and unscrew the tire inflation hose from the tire valve.
x If a tire pressure of 36 – 44 psi (250 – 300 kPa) is reached, continue driving right away and drive at a speed of not more than 50 mph (80 km/h).
x Check tire pressure after 10 minutes of driving ⇒  Check after 10 minutes of driving.
