With the vehicle not moving and the wheels pointed straight, press the b\
rake pedal very firmly to the floor, rapidly press the accelerator pedal to wid\
e open throttle, and then release the brake pedal while fully pressing the accelerator pedal.\
The system initially limits engine speed and manages wheel slip.

The oil and filter should be changed when indicated by the engine oil life system. A Change Engine Oil Soon message will be displayed on the Driver Information Center. Oil and filter change intervals are based on a combination of factors, including engine revolutions, temperature and miles driven. Reset the engine oil life system every time the oil is changed.
