WARNING
The electric motor compartment of any motor vehicle is a potentially dangerous area and can cause serious personal injury.
x Always use extreme caution when doing any work in the electric motor compartment. Always follow commonly accepted safety practices and use common sense. Never risk per-sonal injury.
x Never perform any work in the electric motor compartment unless you know exactly how to carry out the job and have the correct technical information and the correct tools.
x If you are uncertain about what to do, have the work performed by an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified work-shop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon) headlights and H7 bulbs replaced by a qualified technician. Serious personal injury may re-sult from improperly performed work.
x Never open or close the electric motor hood if steam or coolant is escaping. Hot steam or coolant can cause serious burns. Always wait until you no longer see or hear steam or cool-ant escaping from the electric motor.
x Always let the electric motor cool down completely before carefully opening the hood.
x Hot parts of the electric motor and the exhaust system will burn skin on contact.
x When the electric motor has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P) (automatic) or Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the remote control vehicle key is out of range of the vehicle and that the vehicle cannot be started by depressing the starter
button ⇒  Unlocking or locking the vehicle with Keyless Access.
– Always keep children and others away from the electric motor compartment and never leave them unsupervised.
x The electric motor coolant system is under pressure when the electric motor is hot. Never unscrew the coolant expansion tank cap when the electric motor is hot. Hot coolant can spray out and cause severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclockwise direction while applying light downward pressure on the top of the cap.
– Always protect your face, hands, and arms from hot escaping coolant or steam by covering the cap with a large, thick rag.
x Never spill fluids on the electric motor or exhaust system when refilling. Spilling fluids onto hot parts of the electric motor or exhaust system can cause a fire.

Under normal driving conditions, the needle should be in the middle of the gauge. The temperature may go higher when the electric motor is working hard, especially in hot weather.
When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.
The following table explains what to do if the electric motor coolant temperature warning light ~ does not go out a few seconds after the electric motor is started or starts flashing while driving.

Do not mix G 13 with G 12 plus or G 11. Mixing these coolant additives together significantly reduces
corrosion protection ⇒  and can lead to electric motor damage that is not covered by any Volkswagen Limited Warranty.
WARNING
Too little antifreeze protection in the electric motor cooling system can cause electric motor failure and severe injuries.
x Always make sure there is enough of the correct coolant additive to provide proper anti-freeze protection at the coldest temperatures that can be expected where the vehicle will be used.
x At extremely cold temperatures, the coolant could freeze, causing the vehicle to break down. The heater would also not work, and vehicle occupants could be without protection at subfreezing temperatures.
NOTICE
Never mix original Volkswagen electric motor coolant additives with other additives not ap-proved by Volkswagen. Mixing Volkswagen coolant additives with coolant additives made by other manufacturers can seriously damage the electric motor and the electric motor cooling system.
x If the fluid in the electric motor coolant reservoir is any color but pink, then G 13 was mixed with a different electric motor coolant. If this is the case, the electric motor coolant must be replaced immediately. Otherwise serious malfunctions or electric motor damage can occur!
Electric motor coolant and electric motor coolant additives can pollute the environment. Collect leaking operating fluids and dispose of them properly in accordance with applicable environmental laws and regulations.

WARNING
Hot steam and hot electric motor coolant can cause serious burns.
x Never open the hood if you see steam or coolant escaping from the electric motor com-partment. Always wait until you no longer see or hear steam or coolant escaping from the electric motor.
x Always let the electric motor cool down completely before carefully opening the hood. Hot components will burn skin on contact.
x When the electric motor has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P) (automatic) or Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the remote control vehicle key is out of range of the vehicle and that the vehicle cannot be started by depressing the starter
button ⇒  Starter button.
– Always keep children and others away from the electric motor compartment and never leave them unsupervised.
x The electric motor coolant system is under pressure when the electric motor is hot. Never unscrew the coolant expansion tank cap when the electric motor is hot. Hot coolant can spray out and cause severe burns and other serious injuries.
– Turn the cap slowly and very carefully in a counterclockwise direction while applying light downward pressure on the top of the cap.
– Always protect your face, hands, and arms from hot escaping coolant or steam by covering the cap with a large, thick rag.
x Never spill fluids on the electric motor when refilling. Spilling fluids onto hot parts of the electric motor can cause a fire. Under some conditions, the ethylene glycol in electric motor coolant can catch fire.
NOTICE
x Use distilled water only when adding coolant! All other types of water contain chemical compounds that can cause extensive corrosion damage to the electric motor. This can even lead to electric motor failure. If you have added non-distilled water, take the vehicle immediate-ly to an authorized Volkswagen dealer or an authorized Volkswagen Service Facility to have the coolant system drained, flushed, and refilled completely with the proper coolant.
x Refill electric motor coolant only up to the top edge of the marked fill range ⇒ fig. 154. Ex-cess electric motor coolant may be forced out of the electric motor cooling system when it gets hot and cause damage.
x In the case of significant electric motor coolant loss, refill electric motor coolant only when the electric motor is completely cooled down. Significant electric motor coolant loss is a sign of leaks in the cooling system. Have the electric motor cooling system checked immediately by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Otherwise the electric motor may be damaged!
x Do not refill electric motor coolant if there is no coolant in the expansion tank. Air could enter the cooling system. Do not drive the vehicle! Get expert assistance. Failure to do so can result in electric motor damage.
x When changing or topping off operating fluids, make sure that you pour the fluids into the correct reservoirs. Serious malfunctions and electric motor damage can result if you pour operating fluids into the wrong reservoir.
