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 particularly 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.
for additional tips on using your hybrid drive to help reduce fuel consumption.

Driving situations Requirements and conditions Vehicle behavior
Braking energy regeneration (Recuperation).
– Early and even braking with short brake pedal travel.
The vehicle is braked by the electric motor. Most of the kinetic energy is then won back and can be stored in the form of electrical energy in the high-voltage battery
Driving in city traffic.
– Selection of a moderate speed. 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 reduced with moderate acceleration due to higher efficiency of the combustion engine and driving in fully electric mode is possible.
– Careful use of %

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 instrument 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 tachometer will show zero engine speed (zero engine revolutions). The instrument cluster powermeter shows zero.
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) ⇒ Warning when leaving the vehicle.

Description Possible causes among others Possible remedy
Fuse blown. Check fuse and replace if necessary
Fuel consumption higher than indicated.
– Short hauls. – “Jumpy accelerator pedal”.
– Avoid traveling short distances – Drive defensively. – Accelerate smoothly.
Electrical loads switched on. Switch off unnecessary loads.
Engine control malfunctioning. Have the malfunction corrected.
Tire pressure too low. Adjust tire pressure
Driving in the mountains. No direct corrective action possible.
Towing a trailer or roof rack. – Check use. – Remove if not in use.
Driving with heavy payload. No direct corrective action possible.
Driving at high engine speed. Select a higher gear.
