repeated use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensors
The heated oxygen sensors monitor the oxygen
content of the exhaust gases. Readings are fed
into a control module that continuously monitors
engine functions and controls fuel injection. The
ratio of fuel to air into the engine is continuously
adjusted for efficient combustion to help reduce
harmful emissions.

Driving economically

Better driving economy can be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to imme-
diate traffic conditions.
Driving economically with Twin Engine
Plug-in Hybrid vehicles
Plan your driving in order to utilize the electric
motor as much as possible.
An energy-conserving driving style lowers current
consumption from the hybrid battery and helps
increase electric driving range.
Charging
•
Charge the hybrid battery as often as possi-
ble from the electricity grid using the charg-
ing cable. Whenever possible, begin a drive
with a fully charged battery.
•
Check the location of charging points.
•
Where possible, choose parking spaces with
charging points.
Preconditioning
•
If possible, precondition the vehicle with the
charging cable before driving.
•
Avoid parking the vehicle so that the passen-
ger compartment becomes too hot or cold.
Park, if possible, in a climate controlled park-
ing garage.
•
For short drives after using the precondition-
ing function, turn off the climate system
blower if possible.
•
If preconditioning is not possible in cold
weather, use the seat and steering wheel
heating primarily. Avoid heating the entire
passenger compartment, which reduces the
hybrid battery's charge level.
