WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to
break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
x Whenever stalled or stopped for repair, move the vehicle a safe distance off the road, stop
the engine, turn on the emergency flashers, and use other warning devices to warn
approaching traffic.
x Never park the vehicle in areas where the hot catalytic converter and exhaust system can
come into contact with dry grass, brush, spilled fuel, oil, or other material that can catch fire.
x A broken down vehicle presents a high accident risk for itself and others. Switch on
emergency flashers and set up a warning triangle to warn oncoming traffic.

NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.

Vehicle key positions in the ignition switch

Fig. 103 In the ignition switch: Vehicle key positions.

x Always disconnect the connecting cable and close the cover (1) before starting the engine.
WARNING
Improper use of the engine preheating system may cause short circuits, fires, and serious or fatal personal injuries.
x Always connect the connecting cable to a 120 Volt Ground Fault Circuit (GFI) wall outlet. The outlet must be protected from water, moisture and other fluids.
x Never connect the engine preheating system to a conventional socket, regardless of whether the socket is protected or not.

WARNING
Using an outlet or power cables that are incorrect or damaged, using electrical appliances incorrectly, or ignoring safety precautions can result in short circuits, accidents, injuries, and life-threatening electrical shocks.
x Never use a damaged outlet or a damaged power cable.
x Always plug the preheating system into a 120 Volt Ground Fault Circuit (GFI) wall outlet that is properly protected against rain and other moisture.
x Always check the fuse protection of the 120 Volt power source before using the connecting cable.
x Always use a 12 gauge or heavier heavy-duty extension cable that can be properly grounded to a three-prong GFI outlet. The extension cable must not be longer than 100 ft (30 meters).
x Check the cables for damage before every use. Never use a damaged cable. Damaged cables must be replaced. See an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
x Only use the cables provided.
x Always remove the connecting cable before starting the engine.
x Never attempt to alter or repair cables or other electrical components.
x Never let plugs or connectors come into contact with water, moisture, or any other fluids.
If the engine preheating system is used occasionally, test the GFI circuit breaker (Ground Fault Circuit Interrupter) once a month. Test it once a week if the system is used regularly.

NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to
brake. Constant pressure on the brake pedal can make the brakes overheat. Riding the brakes
will substantially reduce braking performance, increase stopping distance, and can cause
complete brake system failure.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and
shift into lower gear (manual or automatic transmission). This will let the vehicle use engine
braking and reduce the load on the brakes. Otherwise, the brake system could overheat and
possibly fail. Only use the brakes when you need them to slow the vehicle down more or to
stop.
When the front brakes are serviced, you should have the rear brake pads inspected at the same
time. The wear of all brake pads should be visually checked regularly. The best way to check for brake
pad wear is to have your authorized Volkswagen dealer or authorized Volkswagen Service Facility
visually inspect the pads through the openings in the wheel rims or from underneath the vehicle. If
necessary, the wheels can be taken off for a more thorough inspection.

Power steering assist is reduced.
Stop, restart the engine, and drive a short
distance. If the yellow warning light does not

Otherwise, have the steering checked
immediately by an authorized Volkswagen
dealer or an authorized Volkswagen Service
Facility.

malfunction.

WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious
personal injuries.
x Always make sure all windows are clear of ice, snow and condensation for good visibility
to the front, sides, and rear.
x Maximum heating output and defrosting performance are not possible until the engine has
reached operating temperature. Wait until you have good visibility before driving off.
x Always make sure you know how to properly use the climate control system as well as the
rear window defroster that you will need for good visibility.
x Never use air recirculation for long periods of time. When the air conditioner is off and
recirculation mode is on, condensation can quickly form on the windows and greatly reduce
visibility.
x Always switch off recirculation mode when it is not needed.

WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents,
collisions and serious personal injury.
x Never switch off the fan for a long period of time and never use air recirculation for a long
period of time because no fresh air will enter the passenger compartment.

NOTICE
x If you think the air conditioner is not working properly or may be damaged, switch it off to
help prevent more damage. Have the air conditioner checked by an authorized Volkswagen
dealer or an authorized Volkswagen Service Facility.
x Air conditioner repair requires specialized knowledge and special tools. Volkswagen
recommends that you see an authorized Volkswagen dealer or an authorized Volkswagen
Service Facility.
x Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation
system can leave residue on the evaporator and on the dust and pollen active carbon filter,
resulting in permanent odors whenever the air conditioner is switched on.
If the air conditioner is switched off, the fresh outside air will not be dehumidified. To help keep
the windows from fogging over, Volkswagen recommends leaving the air conditioner (compressor)
switched on. Press the!

Maximum heating output and defrosting performance are not possible until the engine has
reached operating temperature.
Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle
battery has been replaced may change or delete system settings (including time, date, personal
convenience settings, and programming). Check the settings and correct as necessary once the
vehicle battery has built up a sufficient charge.
