2015 VOLKSWAGEN BEETLE CONVERTIBLE engine

WARNING
Uncontrolled or unintentional opening and closing of the convertible top can cause accidents and serious injuries.
x Never open or close the convertible top unless the vehicle is parked and at a safe distance from traffic.
x Do not open or close the convertible top unless you have made sure that nobody is in the way of the luggage compartment lid, the convertible top supports, and other moving parts.
x Make sure the closed convertible top is latched securely.
x If convertible top operation is interrupted:
– The convertible top may not stop moving immediately. Gravity may cause the converti-ble top to continue moving.
– If you cannot close the convertible top “normally,” use the emergency closing proce-dure to latch it, if necessary.
– Note the messages in the instrument cluster that indicate if the convertible top has closed and latched correctly.
NOTICE
Frequent opening and closing of the convertible top drains the vehicle battery. To help prevent the battery from draining, leave the engine running if opening and closing the roof frequently.
NOTICE
Always close the convertible top before leaving the vehicle and when it may rain or snow. If the convertible top is open, rain or snow can damage the vehicle interior and can cause extensive damage to the electrical system.
NOTICE
The height of the vehicle changes when the convertible top is opening or closing. When there is not enough room above the vehicle, for example in a garage, the convertible could hit some-thing and be damaged.
x Only open or close the convertible top when there is enough room above the vehicle to do so.
If you park the vehicle with the convertible top open, the passenger compartment can be dam-aged by rain or snow, and it is also open to unauthorized persons.
x Always close the convertible top before you leave the vehicle.
x If you must leave things in the vehicle when the top is down, you should lock them in the luggage compartment.

WARNING
If there is a system malfunction, the Automatic Rollover Support System may cause serious injuries by not deploying properly, by not deploying at all, or by deploying unexpectedly.
x If a malfunction exists in the system, have it checked immediately by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. A malfunction exists in the system if the indicator light:
– does not come on when the ignition is turned on;
– does not go out about 5 seconds after you start the engine;
– goes out after switching on the ignition and then comes back on again;
– comes on or flickers when you are driving.
NOTICE
If deployed, the Automatic Rollover Support System can damage the convertible top fabric when opening or closing the top.
x Do not open or close the convertible top if the Automatic Rollover Support System has deployed.

The physical principles of a frontal collision are simple. Both the moving vehicle and the passenger
possess energy ⇒ fig. 53, which varies with vehicle speed and body weight. Engineers call this energy “kinetic energy.”
The higher the speed of the vehicle and the greater the vehicle's weight, the more energy has to be “absorbed” in a crash.
Vehicle speed is the most significant factor. If your speed doubles (for example, from 15 mph to 30 mph – 25 km/h to 50 km/h), the energy increases 4 times!
Because the occupants of the vehicle in the above example are not using safety belts, they are not “attached” to the vehicle. In a frontal collision, they will keep moving at the same speed the vehicle was moving just before the crash, until something stops them - here, the inside of the passenger compartment. Because the occupants of the vehicle in the example are not wearing safety belts, their
entire kinetic energy will be absorbed by impact with the wall ⇒ fig. 54.
The same principles apply to people in a vehicle that is in a frontal collision on the highway. Even at city speeds of 20–30 mph (30–50 km/h), the forces acting on the body can reach one ton (2,000 lbs or 1,000 kg) or more. At greater speeds, these forces are even higher.
Of course, the laws of physics don't apply just to frontal collisions; they determine what happens in all kinds of accidents and collisions.

NOTICE
x To help prevent damage to the engine hood and the windshield wiper arms, lift the wiper arms away from the windshield only when they are in the service position.
x Always carefully fold the windshield wiper arms down against the windshield before driving the vehicle.
Rain sensor

Fig. 88 Inside the front windshield above the inside mirror: Sensitive rain sensor surface.

Possible reasons for changes in the way the rain sensor works
The rain sensor may misread what is happening in the detection zone of its sensitive rain-sensor
surface ⇒ fig. 88 (arrow) and not work for a number of reasons, which may include:
x Worn out wiper blades: Worn out wiper blades may leave a film of water or wiping streaks; this can cause the wipers to run longer, to wipe more often, or to wipe continuously at high speed.
x Insects: Insects hitting the windshield may trigger the wipers.
x Salt streaks: Salt streaks on the windshield from winter driving can cause wiping more often or continuously on glass that is almost dry.
x Dirt: Caked-on dust, wax, any other buildup on the windshield (lotus effect), or car-wash detergent residue can lower the rain sensor's sensitivity and cause it to react too slowly or not at all.
x Crack or chip in the windshield: If a stone hits and chips the windshield while the rain sensor is on, this will trigger a wiper cycle. After that, the rain sensor will recognize the change and recalibrate itself to respond to the sensitive surface's reduced detection zone. Depending on the size of the chip, the sensor's reaction pattern may or may not change.
WARNING
The rain sensor cannot always recognize rain and activate the wipers.
x Switch the wipers on manually when water on the windshield reduces visibility.
Clean the rain sensor's sensitive surface ⇒ fig. 88 (arrow) regularly and check the wiper blades for wear or damage.
To remove wax and coats of polish safely, we recommend using an alcohol-based windshield cleaner.

Driving with an open luggage compartment lid can lead to serious personal injury. If you have to drive with an open luggage compartment lid, make sure that all objects and the lid itself are properly se-cured and take appropriate measures to keep toxic exhaust fumes from entering the vehicle.
WARNING
Driving with an unlatched or open luggage compartment lid can lead to serious personal injury.
x Never transport objects larger than those that fit completely in the luggage compartment, because the luggage compartment lid cannot be fully closed properly.
x After closing the lid, always pull up on it to make sure that it is properly closed and cannot open suddenly when the vehicle is moving.
x Always stow all objects securely in the luggage compartment. Loose objects can fall out of the luggage compartment and injure others on the road behind you.
x Drive carefully; anticipate what other drivers will do.
x Avoid abrupt or sudden acceleration, steering, or braking, because the unlatched luggage compartment lid can move suddenly.
x Always mark objects sticking out from the luggage compartment clearly for others to see. Obey all applicable legal requirements.
x Never use the luggage compartment lid to “clamp” or “hold” objects that stick out of the luggage compartment.
x Always remove any luggage rack or other rack mounted on the luggage compartment lid (along with any luggage on the rack) before driving with an open luggage compartment lid.
WARNING
Driving with an open luggage compartment lid can cause poisonous carbon monoxide in the engine exhaust to get into the passenger compartment.
x Carbon monoxide causes drowsiness, inattentiveness, poisoning, and loss of conscious-ness. It can lead to accidents and severe personal injuries.
x Always keep the luggage compartment lid closed while driving to help keep poisonous exhaust fumes from being drawn into the vehicle.
x Never transport objects that are too large to fit completely into the luggage area, because then the luggage compartment lid cannot be fully closed.
x If you absolutely must drive with the convertible top closed and the luggage compartment lid open, do the following to reduce the risk of carbon monoxide poisoning:
– Close all windows.
– Switch off the climate control system's air recirculation feature.
– Open all air vents in the instrument panel.
– Set the fresh air fan to the highest speed.
NOTICE
Opening the luggage compartment lid changes the vehicle height.
