In the “TAPE” or “CD” mode, the applicable functions are
shown in the lowest part of the display. Push the switch
just below to turn on each function.
(b) Tone and balance
How good an audio program sounds to you is largely
determined by the mix of the treble, mid −range, and bass
levels. In fact, different kinds of music and vocal programs
usually sound better with different mixes of treble, mid− range,
and bass.
A good balance of the left and right stereo channels and of the
front and rear sound levels is also important.
Keep in mind that if you are listening to a stereo recording or
broadcast, changing the right/left balance will increase the
volume of one group of sounds while decreasing the volume
of another.

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.

3“S” mode position
4Shift range position indicator
You can change the shift range position in the “S” mode.
The shift range position can be switched between “6”
(sixth range) and “1” (first range) by moving the selector
lever up to the “+” side or down to the “–” side. The first
shift range position is “5” (fifth range) when the selector
lever is shifted to the “S” position.
However, if you move the lever to the “S” position in AI
shifting control, “5” (fifth range), “4” (fourth range) or “3”\
(third range) will be the first shift range. This is because
the suitable shift range is selected depending on the
driving condition.
31L328
 Shift range position indicator
The shift range position is displayed on the instrument cluster.
 Shift range positions
“6” (sixth range): The most suitable gear is automatically
selected between first and overdrive (sixth) gears according
to vehicle speed and driving conditions. Always use the “6”
(sixth range) position to improve fuel economy and for quiet
driving.
“5” (fifth range): The most suitable gear is automatically
selected between first and fifth gears according to vehicle
speed and driving conditions. This range is suitable for
acceleration such as when you want to pass a vehicle
running ahead of you during high speed driving.

STARTING AND DRIVING
310“4” (fourth range):
The most suitable gear is automatically
selected between first and fourth gears according to vehicle
speed and driving conditions. In the “4” (fourth range)
position, the automatic transmission system will select the
most suitable gear to handle current running conditions
such as hill climbing, hard towing, etc.
“3” (third range): The most suitable gear is automatically
selected between first and third gears according to vehicle
speed and driving conditions. This range is best used when
stronger engine braking is necessary.
“2” (second range): First or second gear will automatically
be selected according to vehicle speed and driving
conditions. This range is to be used when engine braking
stronger than that of the “3” (third range) position is
necessary.
“1” (first range): This gear is fixed in first regardless of
vehicle speed or driving conditions. This range is to be used
when maximum engine braking is necessary.
If you attempt to downshift the transmission when it is not
possible to downshift due to high vehicle speed, a warning tone
sounds twice. 
Maximum allowable speeds
To get on a highway or to pass slower traffic, maximum
acceleration may be necessary. Make sure you observe the
following maximum allowable speeds in each range:
range km/h (mph)1 59 (36)
2 100 (62)
3 146 (90)
NOTICE
Do not downshift if you are going faster than the
maximum allowable speed for the next lower range.
 “S” mode indicator light
“S” mode allows you to use the shift range positions.
The “S” mode indicator light comes on when the selector
lever is shifted into the “S” position. When the “S” mode
indicator light does not come on even with the selector lever
moved to the “S” position, there may be a problem
somewhere in the system. Have your vehicle
checked/repaired by your Lexus dealer as soon as
possible. In this case, you can drive in the same condition
as in the “D” position.

(c) Using engine braking
31L327
“S” mode position
To use the braking power of the engine, downshift the range in
the “S” mode position as follows:
 Shift into the “5” (fifth range) position. The transmission will
downshift to fifth gear and engine braking will be enabled.
If you drive in the “D” position: Shift the selector lever to
the “S” position and “5” (fifth range) will automatically \
be
selected.
If you drive in the “S” position: Shift the selector lever
down to the “–” position by selecting the “5” (fifth ran\
ge). Vehicles with the cruise control —
When
the cruise control is being used, even if you downshift
from “D” or “6” (sixth range) to “5” (fifth range)\
, engine
braking will not be enabled because the cruise control is not
cancelled. For vehicle speed reduction, see page 328.
Vehicles with the dynamic radar/laser cruise control —
When the cruise control is being used in the conventional
(fixed speed) cruise control mode or in the
vehicle −to−vehicle distance control mode, even if you
downshift from “D” or “6” (sixth range) to “5” (fif\
th range),
engine braking will not be enabled because the cruise
control is not cancelled. For vehicle speed reduction, see
pages 359 and 344.
 Shift into the “4” (fourth range) position. The transmission
will downshift to fourth gear when the vehicle speed is or
becomes lower than 197 km/h (122 mph) and more
powerful engine braking will be enabled.
If you drive in the “D” position: Shift the selector lever to
the “S” position and shift the lever down to the “–” posi\
tion
once to select “4” (fourth range). However, when you move
the lever to the “S” position while the AI shifting control is
operating, the first shift range will be “5” (fifth range), “4”
(fourth r ange) or “3” (third range) because the suitable shift
range is selected depending on the driving condition.
If you drive in the “S” position: Shift the selector lever
down to the “–” position to select the “4” (fourth range\
).
