WARNING
Unintended vehicle movement during maintenance work can
cause serious personal injuries.
Never work under the vehicle unless you have safely secured
the vehicle from moving. If you must work under the vehicle
with the wheels on the ground, always make sure that the vehi-
cle is on level ground, that all 4 wheels are chocked to keep
them from moving, and that the key is not in the ignition.
If you must work under a vehicle raised on a floor jack, al-
ways 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. The jack supplied with the
vehicle is not strong enough for this purpose and can collapse
causing serious personal injury.

WARNING
If the hood is not closed properly, it could fly up and block your
view while you are driving. This can lead to a crash and serious
personal injuries.
After closing the engine hood, check that the hood release
lever is properly latched into the hood latch. The engine hood
must be flush with the surrounding auto body parts.
If you ever notice that the hood latch is not properly secured
when the vehicle is moving, stop at once and close it.
Never let anyone get in the way of the hood when closing it.
NOTICE
Make sure the windshield wipers are switched off and the
windshield wiper arms are resting on the windshield before you
open the hood. Otherwise, the windshield wipers and the hood
may be damaged.
Always put the windshield wiper arms down against the wind-
shield before driving the vehicle.
NOTICE
Before opening or closing the engine hood, make sure there is
enough room to do so, for example when the vehicle is in a gar-
age.

there is an alignment tab on the engine oil dipstick, make sure it
lines up with the notch in the guide tube, and that the dipstick goes
all the way in.
7. Remove the dipstick again and read the oil level on the dipstick
⇒ fig. 165 as described below:
(A): Do not add any oil ⇒ . Continue with step 15.
(B): Oil may be added (about 1 pint / 0.5 liter). Continue with step 8

tube and push it all the way in.
9. Remove the cap on the engine oil filler opening ⇒ fig. 166.
10. Only add engine oil that Volkswagen has approved for that

1 pint / 0.5 liter).
11. To help prevent overfilling, you must wait about 1 minute each
time you add oil so that the oil can flow into the oil pan up to the
marking on the dipstick.
12. Read the oil level on the dipstick again before adding another
small amount, if necessary. Never add too much oil ⇒ .
13. After adding oil, the level must at least be in the center of the
⇒ fig. 165 (B) area, but never above (A) ⇒ .
14. After adding oil, securely install the cap on the engine oil filler

should you mix up operating fluids. Otherwise serious malfunc-
tions and engine damage can occur!

WARNING
Changing the vehicle's suspension including use of unap-
proved tire-rim combinations can change airbag performance
and increase the risk of serious personal injury in a crash.
Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
Never use tire-rim combinations that have not been approved
by Volkswagen.
WARNING
Leaving the optional safety belt extender attached to the safety
belt buckle on the front passenger seat when the safety belt is
not being used will prevent the Advanced Airbag System from
working properly and can increase the risk of serious personal
injury in a collision.
Leaving the extender attached to the safety belt buckle when
the front seat is occupied and the safety belt is not being used
will signal to the airbag control unit that the front passenger
seat is occupied and that the safety belt is being used. The
electronic control unit for the airbag system will then receive
incorrect information that will
– cause the safety belt pretensioner to deploy unnecessarily
in collisions and
– cause the front passenger airbag to deploy later in colli-
sions in which the front airbag would otherwise be triggered
earlier to help protect an unrestrained front seat passenger.
Always remove the safety belt extender when it is not needed
and stow it safely.
Never use the safety belt extender to secure a child restraint.
