2. Set the driving pattern selector switch to the "Normal"
position.
Your transmission has a driving pattern selector switch which
allows you to select "Power", "Normal" or "Snow" mode to suit
your driving condition. For ordinary driving, Lexus
recommends that you use the "Normal" position to improve fuel
economy.
3. For more powerful acceleration and sporty driving, use
the "Power" position.
In the "Power" position, the "ECT PWR" light in the instrument
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively than in the
"Normal" position.
For "Snow" mode, see "Electronic Throttle Control
System" on page 315.
