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 313.
STARTING AND DRIVING

" 1 Brake pedal 2 "D" (Drive) position
4. With your foot holding down the brake pedal, shift the
selector lever to "D".
Always use the "D" position to improve fuel economy and quiet
driving. Only in this position, shifting into the overdrive gear is
possible. However, while the engine coolant temperature is
low, the transmission will not shift into the overdrive gear even
in the "D" position. (See "(c) Using engine braking" and "(f)
Good driving practice" for exceptions.)
CAUTION
Never put your foot on the accelerator pedal while
shifting.
