engine coolant VOLKSWAGEN TOUAREG 2012 Owners Manual

The red zone at the end of the scale indicates maximum permissible engine rpm (revolutions per minute) for all gears after the break-in period. Before reaching this region, select the next
higher selector level position (D), or ease your foot off the accelerator ⇒ .

(4) Reset button for the trip odometer display (trip) and button to display the engine code.
– Push and hold the 0.0 button about 1 second in order to reset to zero.
– Keep the 0.0 button pushed for about 3 seconds to display the previous value.
– Push and hold the 0.0 button for more than 10 seconds to display the vehicle's engine code. You must do this when the ignition is on, but the engine is not running.

NOTICE
x To help prevent engine damage, always avoid high engine speeds, full throttle acceleration and heavy engine loads when the engine is cold.
x To help prevent engine damage, the tachometer needle should only enter the red zone (warning zone) briefly.
Up-shifting early into the next higher gear saves fuel and reduces engine noise.

Checklist
If you are uncertain in any way, have the work done by an authorized Volkswagen dealer or author-ized Volkswagen Service Facility. Serious personal injury may result from improperly performed work. Make sure that you check the following items regularly. The best thing is to check them every time you refuel:
d Windshield washer fluid level ⇒  Windshield wiper and washer
d Engine oil level ⇒  Engine oil
d Engine coolant level ⇒  Engine coolant
d Brake fluid level ⇒  Braking and parking
d Tire pressure ⇒  Tires and wheels
d Vehicle lighting necessary for driving safety:
– Turn signals
– Parking lights, low beams and high beams
– Taillights
– Brake lights
– License plate light
Information regarding replacing light bulbs ⇒  Replacing light bulbs.
WARNING
Disregarding the safety-related checklist may lead to accidents and injuries.
x Please note and follow the points listed in the checklist.

WARNING
The engine 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 engine compartment. Always follow commonly accepted safety practices and use common sense. Never risk personal injury.
x Never perform any work in the engine 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 engine 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 coolant escap-ing from the engine.
x Always let the engine cool down completely before carefully opening the hood.
x Hot parts of the engine and the exhaust system will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Apply the electronic parking brake and shift the transmission into Park (P).
– 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.
– Always keep children and others away from the engine compartment and never leave them unsupervised.
x The engine coolant system is under pressure when the engine is hot. Never unscrew the coolant expansion tank cap when the engine 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 engine or exhaust system when refilling. Spilling fluids onto hot parts of the engine or exhaust system can cause a fire.

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

x If the fluid in the engine coolant reservoir is any color but pink, then G 13 was mixed with a different engine coolant. If this is the case, the engine coolant must be replaced immediately. Otherwise serious malfunctions or engine damage can occur!
Engine coolant and engine coolant additives can pollute the environment. Collect leaking operat-ing fluids and dispose of them properly in accordance with applicable environmental laws and regula-tions.
Checking engine coolant level and topping off

Checking engine coolant level
x When the engine is cold, check the engine coolant level relative to the marking on the side of the
expansion tank ⇒ fig. 319.
x If the coolant level in the tank is below the minimum mark (“min”), add coolant. When the engine is warm, the engine coolant level may be slightly above the upper edge of the marked range.
Adding engine coolant
x Always protect face, hands and arms from hot escaping coolant or steam by covering the cap with a large, thick rag.
x Carefully unscrew the cap ⇒ .
x Add only new engine coolant according to Volkswagen specifications ( Engine coolant specifica-
tions) ⇒ .
x The engine coolant level must be inside the marks on the side of the reservoir ⇒ fig. 319. Do not
fill above the top edge of the filling range! ⇒ .
x Screw the lid tightly.
x Even in an emergency, do not use any other kind of coolant additive if engine coolant meeting Volkswagen specifications (Engine coolant specifications) is unavailable! Instead, add distilled water
only ⇒ . As soon as possible, have the correct coolant ratio restored using engine coolant that
meets Volkswagen specifications ⇒  Engine coolant specifications.
WARNING
Hot steam and hot engine coolant can cause serious burns.
x Never open the hood if you see steam or coolant escaping from the engine compartment. Always wait until you no longer see or hear steam or coolant escaping from the engine.
x Always let the engine cool down completely before carefully opening the hood. Hot com-ponents will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Apply the electronic parking brake and shift the transmission into Park (P).
– 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 engine compartment and never leave them unsupervised.
x The engine coolant system is under pressure when the engine is hot. Never unscrew the coolant expansion tank cap when the engine 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 engine or exhaust system when refilling. Spilling fluids onto hot parts of the engine or exhaust system can cause a fire. Under some conditions, the ethylene glycol in engine coolant can catch fire.
