2013 VOLKSWAGEN TOUAREG engine coolant

.NOTICE
If the vehicle is not used for a longer period, the high-voltage battery will run down. To keep
the high-voltage battery in good condition, the vehicle needs to be driven at least every 2
months for at least 30 minutes or 15 miles (20 km).
x If the high-voltage battery is dead, the gasoline engine will not start. Contact an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop
for assistance.
Special considerations for hybrid vehicles

Engine compartment covers (1) and (3) must be removed in the following situations:
x Changing light bulbs in the left headlight assembly.
Engine compartment covers (1) and (2) must be removed in the following situations:
x Changing light bulbs in the right headlight assembly.
x Adding engine coolant to the low temperature coolant circuit .
Removing engine compartment cover
When removing any part of the engine compartment cover, always pull CARefully on the relevant
attachment points ⇒ .
x Open the engine hood

Automatic window fog detection
Automatic window fog detection checks whether the windows are fogged up and if necessary
automatically adjusts the air flow to the windshield and side windows or switches on the windshield
heating. If the fan or the air conditioner AC is turned off, automatic window fog detection cannot work
properly.
Residual heat mode
The residual engine heat can be used for a limited time to heat the passenger compartment when the
ignition is switched off.
x Switch off the ignition.
x Push the REST .button. The feature will appear in the Climatronic display.
x Press the REST .button again to switch the feature off early.
The feature is switched off if it is draining the battery too much, and it does off automatically after 30
minutes. The fan speed is reduced to save energy.
Applying driver settings to all climate zones
The driver-side settings for temperature, fan speed, and air distribution can be applied to all of the
other climate zones.
x Push the SYNC .button. The indicator light in the button lights up and the changes are applied to
all climate zones.
x Push the SYNC .button again to cancel the feature.
The synchronization feature is deactivated if individual settings are entered for one of the other
climate zones using the Climatronic control unit. In this case, the indicator light in the SYNC .button
goes out.
Air conditioner does not work
The air conditioner may not switch on for one the following reasons:
x The engine is not running (or a hybrid vehicle is not ready to drive).
x The fan is turned off.
x The air conditioner fuse has blown.
x The ambient air temperature is colder than +38 °F (+3 °C).
x The air conditioner compressor has been temporarily switched off due to excessive engine coolant
temperature.
x There is another malfunction in the vehicle. Have the air conditioner checked by an authorized
Volkswagen dealer or authorized Volkswagen Service Facility.
Special considerations
When it is very hot and humid outside, water condensation can drip from the air conditioner
evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.
The climate control system adjusts the passenger compartment temperature as fast as possible
considering the outside temperature.
Due to residual moisture in the air conditioner, the windshield may fog up after the engine is
started. Switch on the windshield defroster to help evaporate the condensation as quickly as possible.
The air coming out the vents and flow through the passenger compartment and out through the
vents below the rear window. Do not cover these slots with clothing or other objects.

.WARNING
Unintended vehicle movement during maintenance work can cause serious personal injuries.
x Never work under the vehicle unless you have safely secured the vehicle from moving. If
you must work under the vehicle with the wheels on the ground, always make sure that the
vehicle is on level ground, that all 4 wheels are chocked to keep them from moving, and that
the key is not in the ignition.
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle
is safely supported on safety stands intended for that purpose that are strong enough to
support the weight of the vehicle. The jack supplied with the vehicle is not strong enough for
this purpose and can collapse causing serious personal injury.
.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
workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID - High Intensity Discharge (Xenon)
lamps and HO7 bulbs replaced by a qualified technician. Serious personal injury may result
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
escaping 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:
– Firmly 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.
