2013 VOLKSWAGEN TOUAREG fuel

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.

Remove unnecessary aftermarket components
The more aerodynamic the vehicle, the less fuel it will consume. Aftermarket components such as
bicycle racks reduce its aerodynamic performance.
Therefore, remove unnecessary structures and unused rack systems, particularly if planning to drive
at higher speeds.

.WARNING
When powered by the electric motor, the vehicle makes much less noise, both when idling
and driving, than when it is running on the internal combustion engine. It is much harder or
even impossible for the drivers of other vehicles and above all for cyclists, pedestrians, and
children to hear the vehicle when it is running on electrical power.
x Pedestrians and others can be struck and seriously injured because they cannot hear the
vehicle and tell that it is getting close to them, for instance when you are parking, backing
up, or driving in a low-speed zone where there is likely to be pedestrian traffic.
x Always watch out for pedestrians, especially small children, cyclists, and others who may
not hear the vehicle or realize that it is about to move or will cross their path of travel.
x Always be especially CAReful in residential areas, school zones, and other places where
the speed of motor vehicles is restricted and pedestrians may be at greater risk,
x Make sure the ignition and the hybrid drive system have both been turned off before
leaving the vehicle.
.WARNING
Never leave the vehicle when hybrid drive system indicator lights are still lit. The vehicle can
move if the accelerator is depressed even though the combustion engine has been stopped.
This can cause accidents and severe or lethal injuries.
x Make sure the transmission is in Park (P) before you get out of the vehicle.
.WARNING
Never support the vehicle with cinder blocks, bricks, or other objects to inspect it. The
vehicle could slip or move suddenly and cause an accident with serious personal injury.
.WARNING
Never let the hybrid battery get wet. Liquids and other fluids can cause short circuits,
electrical shock, burns, and explosions.
x Never CARry large amounts of liquids or other fluids in the luggage compartment.
x Always make sure that any containers with liquids and other fluids are properly secured
and tightly closed to prevent leakage during normal driving as well as hard cornering,
braking, and other vehicle maneuvers. Leaking liquids can get into the cover of the high-
voltage battery and the high-voltage cable connections. This can damage the electrical
system and the high-voltage battery.
.Never drive until the fuel tank is completely empty. There may not always be enough charge in
the high-voltage battery to get to the next gas station.
Warning and indicator lights

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.

could be used for reducing fuel consumption with a foresighted driving style. Even in this case, the rev
counter in the instrument cluster displays zero engine speed (0 engine revolutions).
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
tachometer will show zero engine speed (zero engine revolutions).
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
cannot 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
transmission is in Park (P) or Neutral (N) .

In order to: You must ⇒fig.134Result:
Reduce set speed (while
cruise control is actively
controlling vehicle
speed).
Push the lever briefly to the
30%%$ – position (–) to reduce
speed in increments of 5 mph
(10 km/h) and store.
Cruise control will slow the vehicle
down without braking by reducing the
flow of fuel to the engine until the new
lower speed is reached and saves the
new lower speed in the memory. Push and hold the lever in the
30%%$ – position (–) to reduce the
set speed until the lower desired
speed is reached and the button
is released.
Switch off cruise control. Move the lever to the /&&position
(B).
System is switched off. The set speed
is deleted.

Driving downhill with cruise control
If cruise control cannot maintain constant speed while driving downhill, slow the vehicle with the foot
brake and downshift if necessary.
Automatic deactivation
Cruise control speed regulation is automatically deactivated or temporarily interrupted:
x If the system detects an error that could affect the function of the cruise control.
x If the vehicle has accelerated and goes faster than the stored speed for a longer time.
x If the brake or clutch pedal is depressed.
x If the vehicle shifts gear (manual transmission).
x If an airbag deploys.
