heating VOLKSWAGEN TOUAREG 2013 2.G User Guide

When driving on the highway or freeway, a constant, moderate speed is more efficient and
economical than constantly accelerating and braking. Usually you can reach your destination just as
quickly by driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally
conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the climate control system has to produce starkly
contrasting temperatures, it requires a large amount of energy, which is generated by the engine. The
temperature in the vehicle should therefore not be extremely different from that of the outside
temperature. It may be helpful to ventilate the vehicle before driving and then to drive a short distance
with the windows open. After that, switch on the air conditioner with the windows closed. Keep the
windows closed when driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the windshield and rear window defroster as soon as the windows are free of fog and
ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
x Towing a trailer.
Fuel-efficient driving

Driving
situations Requirements and conditions Vehicle behavior
– CAReful use of E-MODE button
⇒ fig. 251.
The high-voltage battery discharges quickly
with the E-MODE button switched on. This
can increase fuel consumption since driving
in electric mode is preferred in this case,
even though the combustion engine would
be more efficient.
Driving on
country roads
and highways.
– Conscious easing off of the
accelerator, to enable longer sailing
distance.
By easing off the accelerator, the
combustion engine is automatically
switched off and de-clutched. The vehicle
glides without engine power.
- Reducing speed by easing off the
accelerator early and not by
braking.
Sailing possible. Reduction of speed this
way is more fuel-efficient than through
braking.
- Avoid speeds of over about 160
km/h (99 mph).
Efficient sailing is possible with a speed of
about 160 km/h (99 mph) .
- CAReful selection of gear (S).
Sporty driving style with activated sport
programme increases fuel consumption.
Efficient sailing in sport programme with
combustion engine automatically switched
off is possible with a speed of about 70
km/h (43 mph).
Driving in cold
months.
- Do not warm up the combustion
engine by running it with the
vehicle stationary.
The temperature of the combustion engine
increases very slowly, but fuel consumption
increases considerably.
– CAReful use of heating for
windshield and the rear window,
outside mirror, seat and steering
wheel.
This prevents energy from being lost and
saves energy for the electric motor.
- Never leave the vehicle in a
garage over night.
This prevents the high-voltage battery and
the vehicle interior from cooling down too
much. The optimal temperature of the high-
voltage battery is reached quicker at the
beginning of the journey and the
combustion engine can be switched off
quicker when the vehicle interior is
sufficiently heated.

Heating and air conditioning

.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 fast defrosting will only be possible after 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 heating and ventilation systems 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 a long
period of time because no fresh air will come into 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 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 AC .button.
.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.
.Keep the air intake slots in front of the windshield free of ice, snow and leaves in order to
maintain proper functioning of the heating and ventilation systems.
.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

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
x Even if empty, portable fuel containers can leak and cause a fire and serious personal
injuries, especially in a crash.
x If, under exceptional circumstances, you must transport a portable fuel container, please
observe the following:
For your safety, we strongly recommend that you do not travel with a portable fuel container
in your vehicle.
– Never fill a portable fuel container while it is anywhere in or on the vehicle (for
example, in the luggage compartment or on the rear hatch). Static electricity can build up
while filling and can ignite fuel vapors, causing a fire.
– Always place a portable fuel container on the ground before filling. Never spill fuel
inside the vehicle or luggage compartment. Fuel vapors are highly flammable.
– Always keep the filler nozzle completely inside the portable container before and
during filling.
– If filling a portable container made of metal, the filler nozzle must always be in contact
with the container. This will help prevent static electricity from discharging and causing a
fire.
– Always observe local and state or provincial laws about the use, storage, and
transportation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as
ANSI/ASTM F852-86.
.NOTICE
x Remove fuel spills from the vehicle immediately to help prevent damage to the paint, tires,
and wheel housings.
x Refueling with gasoline when your vehicle has a diesel engine or refueling with diesel fuel
when your vehicle has a gasoline engine can cause very serious and expensive engine and
fuel system damage that is not covered by any Volkswagen Limited Warranty.
x If you put any amount of incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance. These fuels contain substances that can severely
damage the fuel system and the engine if the engine is started.
x Vehicles with diesel engines must never be refueled or driven with gasoline, kerosene,
heating oil, or other non-specified fuels that have not been expressly approved for use with the
diesel engine. Other kinds of fuel will cause serious damage to the fuel system and the engine
that is not covered by any Volkswagen Limited Warranty.
.Fuels can pollute the environment. Spilled fuel must be collected and disposed of properly,
following all applicable environmental regulations.
.There is no emergency release for the fuel filler flap. Contact an authorized Volkswagen dealer
or an authorized Volkswagen Service Facility for assistance if necessary.

Cold diesel engines normally produce louder noises during winter conditions than during warmer
periods. In addition, the exhaust gases may be light blue in color until the engine has warmed up. The
exhaust gas volume varies depending on the outside temperature.
Do not let your diesel engine idle unnecessarily after a cold start. Driving off slowly will shorten the
warm-up period.
.WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.
.NOTICE
x The vehicle's diesel engine was designed solely for use with ULSD fuel. For this reason,
never use gasoline, heating oil, or other fuels that have not been expressly approved for use
with the diesel engine. These fuels contain substances that will severely damage the fuel
system and the engine. Such damage will not be covered by any Volkswagen Limited
Warranty.
x If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same
applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic
part. Wash the contaminated vehicle parts right away with soap and warm water to help
prevent leaks and serious damage.
x The vehicle is designed to run on diesel fuel containing methyl ester bio diesel in
concentrations of 5% or less. Never use methyl ester bio diesel in blend levels higher than 5%
(5% methyl ester blends are sometimes designated or labeled as B5). The properties of methyl
ester bio diesel blends in levels greater than 5% may cause serious damage to the fuel
injection system and to the engine. This could lead to expensive repairs that will not be
covered by any Volkswagen Limited Warranty.
x Damage to the engine and fuel system and performance problems caused by using fuels
that are different from those specified above or by using “starting assist fluids” are not the
responsibility of Volkswagen and are not covered under the Emission warranties or any other
Volkswagen Limited Warranty.
