Checklist
For your own safety and that of your passengers, carry out the following steps in the order listed ⇒ :
1. Park the vehicle at a safe distance from traffic and on a suitable surface ⇒ .
2. Switch on emergency flashers by pressing the  switch ⇒ fig. 172.
3. Apply the parking brake to help prevent the vehicle from moving .
4. Shift the transmission into Park (P) (automatic) or Neutral (manual only) .
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 personal 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.
They can cause fires 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
Changing a wheel, especially 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. Move the vehicle a safe distance off
the road where it is safe to change the wheel.
x Always make sure that all passengers, especially children, are in a safe place outside the
vehicle and away from the vehicle and traffic (such as behind a guard rail).
x Turn on the emergency flashers and set up another warning device about 25 yards
(25 meters) behind the vehicle to warn approaching traffic.
x Change a wheel by yourself only if you are familiar with the necessary steps. Otherwise,
get expert assistance.
x Always switch the engine off, firmly apply the parking brake, and shift the transmission
into Park (P) (automatic transmission) or any gear (manual only) to help prevent the vehicle
from moving suddenly and slipping off the jack.
x Always make sure that the ground is level and firm. If necessary, place the jack on a large
and sturdy board or on a similar ground support.
x Always block the wheel diagonally opposite the wheel being changed with chocks or other
similar things.
x If you are towing a trailer, always unhitch it from your vehicle before starting to change
the wheel. Always apply the trailer brakes firmly and make sure the trailer cannot move
unintentionally.
x Always use proper and undamaged tools when changing a wheel.
x Once a wheel is lifted off the ground, having the transmission in Park (P) or in gear will not
prevent sudden vehicle movement.
x Always use a jack that has been approved by the manufacturer for your vehicle. Never use
other jacks, even if they have been approved for use on other Volkswagen models.
x To reduce the risk of losing control, crashes, and serious personal injuries, never loosen
the screws on rims with threaded rim rings.
x After changing a wheel, have the wheel bolt tightening torque checked with an accurate
torque wrench.
x After changing a wheel or tire, reset the Tire Pressure Monitoring System .

Before removing the jumper cables
x Switch off the headlights (if they are on).
x 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 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.
6. If necessary, unscrew the towing eye on the front of the vehicle or! Bookmark not defined..
WARNING
Improper use of jumper cables when jump-starting a vehicle with a dead battery can cause
the battery to explode, leading to serious personal injury. To help reduce the risk of battery
explosion:
x All work on the batteries or the electrical system in your vehicle can cause serious acid
burns, fires, or electrical shocks. Always read and heed the following WARNINGS and safety
precautions before working on the batteries or the electrical system , Vehicle battery.
x Always wear proper eye protection. Never lean over the vehicle battery.
x Attach the jumper cables in the correct order: first the positive cable, then the negative
cable.
x Never connect the negative cable from the vehicle providing starting assistance to parts
of the fuel system or to the brake hoses or brake lines.
x Never allow the non-insulated parts of the battery clamps to touch.
x Never allow the jumper cable attached to the positive battery terminal to contact metal
parts of the vehicle.
x Check the battery acid level indicator window on the vehicle battery. Use a flashlight,
never a match, cigarette lighter, or other open flame. If you cannot see the color of the
window clearly, or if it is light yellow or colorless, do not jump-start the vehicle. Get expert
assistance.
x Avoid electrostatic discharge in the vicinity of the vehicle battery. Sparks may cause the
hydrogen gas escaping from the vehicle battery to ignite.
x Never jump-start a vehicle with a battery that is damaged or frozen or that was frozen and
has thawed. The battery can explode. Replace the battery instead.
x Always follow the instructions of the jumper cable manufacturer.
x Always make sure that the battery providing starting assistance has the same voltage as
the dead battery (12 V) and about the same capacity (see battery label).
x Batteries give off explosive hydrogen gas. Always keep fire, sparks, open flame and
smoking materials away from batteries.
x Never connect the negative cable from the other vehicle directly to the negative terminal
of the dead battery. The hydrogen gas from the battery is explosive.
x Never short out the battery terminals by connecting the positive (+) and negative (-)
terminals with each other.
