2011 VOLKSWAGEN TOUAREG Temperature

Driving situa-
tions
Requirements and
conditions Vehicle behavior
– 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 acti-
vated sport program increases
fuel consumption. Efficient
sailing in sport program with
combustion engine automati-
cally 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 vehi-
cle stationary.
The temperature of the com-
bustion engine increases very
slowly, but fuel consumption
increases considerably.
– Careful use of heating
for the rear window,
outside mirror, steering
wheel and front seats.
This prevents energy from
being lost and saves energy
for the electric motor.
– Leave the vehicle in a
garage overnight.
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 inte-
rior is sufficiently heated.

This depends on vehicle conditions of the hybrid drive system is normal and is designed to save fuel. The power steering and the braking assistance systems remain active. In certain situations it may be necessary for the system to start the combustion engine even when the vehicle is not moving. With prolonged driving in traffic jams, the combustion engine will be switched on and off to charge the high-voltage battery for the following start-stop phase.
Sailing
If the accelerator is not depressed and the lever is in Drive (D), the internal combustion engine is switched off even at higher speeds. The vehicle then decelerates slower than conventional vehicles.
This feature can be used to help reduce fuel consumption when you keep traffic conditions in mind and can anticipate the vehicles power requirements. Even in this case, the rev counter in the instru-ment cluster displays zero engine speed (0 engine revolutions). The instrument cluster powermeter shows zero.
Brake energy regeneration (Recuperation/charge)
When the vehicle brakes, the electrical energy is generated by the electric motor, which works as an alternator and charges the high-voltage battery. The same thing occurs while the vehicle is coasting to a stop or driving downhill.
Energy regeneration is shown in the instrument cluster display or on the Infotainment System screen. The combustion engine may be switched off automatically in this situation. The instrument cluster powermeter registers below zero.
When the high voltage battery is fully charged, there is no brake energy recuperation, and therefore no engine braking. Recuperation and engine braking are also automatically reduced if the vehicle detects that the road conditions do not permit sufficient contact between the wheels and the road surface.
Automatic starting - combustion engine
The combustion engine is started automatically in a number of situations.
x Engine temperature is too low.
x Catalytic converter temperature is too low.
x High-voltage battery being charged at high rate when decelerating. The high-voltage battery can-not absorb any more energy and for this reason the electric motor cannot brake the vehicle. The combustion engine comes on to help slow the vehicle down (engine brake).
x Engine hood is open.
x Leaving the vehicle when the electric motor is still “live”. The status of the electric motor is not always obvious, particularly when the combustion engine is not running. The combustion engine will therefore start if the driver's safety belt is unlatched or the driver's door is opened when the transmis-
sion is in Park (P) or Neutral (N) ⇒  Warning when leaving the vehicle.

Vehicles with oversize loads
Under certain circumstances vehicles carrying oversize loads or loads that exceed the vehicle dimen-sions, like flat-bed trailer trucks, can't be recognized correctly by the ACC. Switch off ACC when driving behind such vehicles.
Other vehicles changing lanes
Vehicles that change into your lane within a short distance can only be detected by the radar sensor
once they are within sensor range ⇒ fig. 278 (C). The result is a delayed reaction by the Adaptive Cruise Control.
Stationary vehicles
If a vehicle detected by Adaptive Cruise Control turns or changes lanes and there is a stationary vehicle in front of that vehicle, the system will not react to the stationary vehicle (D).
Narrow vehicles
Narrow vehicles, such as motorcycles traveling ahead, are often detected late or not at all under some circumstances.
Oncoming vehicles
ACC does not detect oncoming vehicles on your lane.
Metal objects on the road
Metal objects on the road, such as tracks, can cause irritations for the ACC due to falsely reflected radar signals and therefore lead to unwanted reactions of the system, such as abrupt braking maneu-vers.
Radar sensor impaired by rain and dirt
If the radar sensor function is impaired by heavy rain, spray, snow or mud, Adaptive Cruise Control switches off temporarily. ACC not available. No sensor view! appears in the instrument cluster display.
When Adaptive Cruise Control is reactivated after this message is displayed, it functions like a “stand-ard” cruise control system. It maintains the set speed but it does not regulate the distance to the vehicle ahead.
Overheated brakes
Adaptive Cruise Control may switch off temporarily if the brakes overheat significantly, for example from braking maneuvers or driving down steep slopes. ACC not available appears in the instru-ment cluster display. Adaptive Cruise Control cannot be activated.
Adaptive Cruise Control can be activated again once the temperature of the brakes decreases suffi-ciently. The message ACC not available in the instrument cluster switches off.
If the message ACC not available does not switch off, there is a malfunction. Contact your au-thorized Volkswagen dealer.
Trailer towing
When towing a trailer, ACC and the Forward Collision Warning system (Front Assist) may work only with limited functionality.
Text messages in the instrument cluster display

Text message Meaning

WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious person-al 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, colli-sions 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 rec-ommends 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 sys-tem can leave residue on the evaporator and on the dust and pollen active carbon filter, result-ing 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 !

Button/Knob More information. Front Climatronic controls ⇒ fig. 301.

Defog / defrost button: The incoming outside air is directed
to the windshield, and air recirculation is automatically dis-
abled. At temperatures above +38 °F (+3 °C), the air is
dehumidified and the fan is set a to high speed so as to
defog/defrost the windshield as quickly as possible.

3 Air recirculation
=
Rear window defroster: works only when the engine is run-
ning or, on hybrid vehicles, when the vehicle is ready to
drive; switches itself off after 10 minutes at the latest.
!

The air recirculation mode helps prevent outside air from entering the vehicle interior.
In very hot or cold outside temperatures, temporarily switch to manual air recirculation in order to cool or heat the vehicle interior faster.
For safety reasons, air recirculation is switched off if you push the  button ⇒ .
Switching air recirculation on and off manually
Switching on: Press the 3 button repeatedly until the indicator light in the button comes on.
Switching off: Press the 3 button repeatedly until the indicator light in the button goes out.
Switching air recirculation on and off automatically
x Press the CLIMATE Infotainment button.
x Tap the Extras function key.
x Switch automatic air recirculation on or off by tapping the Automatic air recirculation function key.
If the check box in the function key is checked =, automatic air recirculation is switched on.
What automatic air recirculation does
In automatic air recirculation mode, fresh air will enter the passenger compartment. If the system detects an increased concentration of pollutants in the outside air, it automatically switches to air recirculation. As soon as the pollutant level is back in the normal range, air recirculation is switched off.
Unpleasant odors cannot be detected by the system.
To keep the windows from fogging up, automatic air recirculation is not switched on automatically in certain circumstances.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents, colli-sions and serious personal injury.
x Never use air recirculation mode over an extended period of time, since no fresh air will enter the passenger compartment.
x 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.
NOTICE
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.
When backing up and while the automatic wiper/washer is operating, air recirculation is briefly activated to avoid unpleasant odors in the passenger compartment. This feature only works if automat-
ic air recirculation is enabled ⇒  Switching air recirculation on and off automatically.
Heated steering wheel

The heated steering wheel function only works when the engine is running or is drive-ready (hybrid).
The steering wheel gets heated to about 77 °F (+25 °C) and holds the temperature there.
Switching the heated steering wheel function on and off
x Press the \b button in the upper center console.
x OR: Press the buttonCLIMATE on the infotainment screen and the touch the \b button to switch on or off.
Automatic deactivation
The heated steering wheel function switches off automatically, if:
x The engine is switched off.
x When the overall energy consumption is too high, like when too many devices and functions are activated in the vehicle.
x The heated steering wheel system malfunctions.
WARNING
Certain medical conditions, such as paralysis and diabetes, and certain medications can increase the risk of serious burns when the heated steering wheel function is switched on.
x Never use the heated steering wheel function if you or your passengers are at risk of be-ing burned because of a medical condition. Take regular breaks and get out of the vehicle, particularly on long trips. Consult your doctor for advice regarding your specific condition.

NOTICE
x Use only AdBlue® or any Diesel Exhaust Fluid that expressly conforms to International Organization for Standardization specification ISO 22241-1. Using a DEF that does not meet the requirements of ISO 22241-1 can seriously damage your vehicle’s engine.
x Never mix water or any other substances or additives with AdBlue. Damage caused by such additives will not be covered by any Volkswagen Limited Warranty.
x Never put AdBlue into the diesel fuel tank! Otherwise the engine may be damaged!
x Do not carry a refill container in the vehicle all the time or routinely. Due to temperature fluctuations and damage, the container could start leaking and the AdBlue could damage the vehicle interior.
Dispose of the refill container in an environmentally-responsible manner.
Appropriate AdBlue refill containers can be obtained from an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
