WARNING
Never leave the vehicle unattended while the engine is running.
The vehicle could move suddenly, especially when the vehicle
is in gear, resulting in accidents and personal injury.
WARNING
“Starting fluids” can explode and can cause a “run-away” vehi-
cle condition.
Never use starting assist fluids.
NOTICE
You can damage the starter or the engine if you try to start the
engine when the vehicle is still moving, or if you try to restart the
engine right after switching it off.
Avoid high engine speeds, full throttle acceleration, and heavy
engine loads when the engine is cold.
Do not try to start the engine by pushing or towing the vehicle.
Unburned fuel can get into the catalytic converter and damage it.
The steering column may also be locked.
Do not let your vehicle warm up while standing; instead, start
driving right away after making sure that you have good visibility
through all windows. This will help the engine reach operating tem-
perature faster and keep down emissions.
If the remote control vehicle key battery is weak or dead, the
starter button will not start the engine. In this case, start the engine by
inserting the vehicle key in the ignition switch ⇒ Vehicle key positions
in the ignition switch.
Major consumers of electricity are temporarily switched off when
the engine is being started.
After starting a cold engine, there may be increased operating
noises for a few seconds. This is normal and harmless.

Only use maintenance-free vehicle batteries meeting standards
TL 825 06 and VW 7 50 73. These standards must date from Au-
gust 2008 or later.

WARNING
Serious injuries can result if the emergency closing and open-
ing procedures are used carelessly.
Never leave children, disabled persons, or anyone who can-
not help themselves in the vehicle. The doors can be locked
with the remote control vehicle key. This could result in people
being trapped in the vehicle in an emergency.
A closed vehicle can become very hot or very cold, depend-
ing on the season. Particularly in the summer, heat buildup in
the passenger and luggage compartment of a parked vehicle
can result in temperatures in the vehicle that are much higher
than the outside temperatures. Temperatures can quickly reach
levels that can cause unconsciousness and death, particularly
to small children.
WARNING
Careless opening and closing of the doors, the luggage com-
partment lid, and the power sunroof is dangerous and can
cause serious personal injury.
Open or close the doors, the luggage compartment lid, and
the power sunroof only when no one is in the way.
NOTICE
If the vehicle's battery fails or the power windows won't work,
the door windows are not lowered when the door is opened or
closed. Always close and open the door carefully to help prevent
damage to the window, the paint, or the rubber seal.
NOTICE
To help prevent vehicle damage, carefully remove and properly
reinstall parts after emergency locking or unlocking.
