Adjust the tire pressure
The proper tire pressure helps reduce rolling resistance as well as fuel consumption.
When purchasing new tires, always make sure that the tires are optimized for lower rolling resistance.
Use low viscosity engine oil
Fully “synthetic,” low viscosity engine oils that expressly comply with Volkswagen oil quality standards reduce fuel consumption. Low viscosity engine oils reduce the frictional resistance on the engine and are distributed more evenly and quickly, particularly when cold-starting the engine. The effect is partic-ularly apparent in vehicles that frequently travel short distances.
Always ensure the right engine oil level is maintained and keep to the scheduled service intervals (engine oil changes).
Make sure the engine oil that you purchase expressly complies with Volkswagen oil quality standards and is the oil approved by Volkswagen for your vehicle.
Avoid unnecessary weight
The lighter the vehicle, the more economical and eco-friendly it will be. For example, an extra 220 lbs (100 kg) of weight increases fuel consumption by up to 1 pint per 60 miles (0.3 l/100 km).
Remove all unnecessary items and unnecessary dead weight from the vehicle.
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.
See additional tips on using your hybrid drive to help reduce fuel consumption.

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 leav-ing 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 fatal 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 vehi-cle 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, electri-cal 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, brak-ing, 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.
When outside temperatures are low, a cold high-voltage battery can affect how the combustion engine starts up and can also reduce the vehicle's range in electric drive.

Driving in fully electric mode at
this level is possible only with
a speed of up to approximately
50 km/h (31 mph).
– Avoid full acceleration.
The fuel consumption is re-

– 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.

Refueling

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 exam-ple, 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 dur-ing 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 transpor-tation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as AN-SI/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.
