(c) Using the “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for strong engine\
braking
as described previously.
With the selector lever in “3”, “2” or “L”, you can start the vehicle
in motion as with the lever in “D”.
With the selector lever in “3” or “2”, the vehicle will start in firs\
t
gear and automatically shift to second gear or third gear.
With the selector lever in “L”, the transmission is engaged in
first gear.
NOTICE
 Be careful not to overrev the engine. Watch the
tachometer to keep engine rpm from going into the
red zone. The approximate maximum allowable
speed for each position is given below for your
reference.
“3” 144 km/h (90 mph). . . . . . . .
“2” 92 km/h (58 mph)
. . . . . . . . .
“L” 51 km/h (32 mph)
. . . . . . . . .
 Do not continue hill climbing or hard towing for a long
time in the “3”, “2” or “L” position. This may cause
severe automatic transmission damage from
overheating. To prevent such damage, “4” position
should be used in hill climbing or hard towing.
(d) Backing up
1Brake pedal2“R” (Reverse) position
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the
selector lever to the “R” position.
NOTICE
Never shift into reverse while the vehicle is moving.
Vehicles with driving position memory system —
When the shift lever is shifted into “R” position, the outside rear
view mirrors automatically down to help backing up. For
details, see page 231.

STARTING AND DRIVING

CAUTION
Never attempt to move the selector lever into “P” under
any circumstances while the vehicle is moving. Serious
mechanical damage and loss of vehicle control may
result.
(f) Good driving practice
 If the transmission repeatedly shifts up and down between
fourth and overdrive gears when climbing a gentle slope,
shift the selector lever to the “4” position. Be sure to shift the
selector lever to the “D” position after climbing the slope.
 When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or parking brake to hold the
vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.

(g) If you cannot shift the selector lever
If you cannot shift the selector lever even though the brake
pedal is depressed, use the shift lock override button. For
instructions, see “If you cannot shift automatic transmission
selector lever” on page 524.
(h) Driving in snow mode
Use this mode when starting your vehicle in ice or snow.
To set the snow mode, push the switch. In the “ECT SNOW”
indicator on the instrument cluster is on. To cancel the snow
mode, push the switch again. The “ECT SNOW” indicator light
will go off when the snow mode is cancelled.
If the engine is turned off with the snow mode is on, the snow
mode is cancelled when the engine is restarted.

AUTOMATIC TRANSMISSION(multimode type)
Your automatic transmission has a shift lock system to
minimize the possibility of incorrect operation. This
means you can only shift out of “P” position when the
brake pedal is depressed with the ignition switch in “ON”
position. ( )

1“P” (Park) position2 “N” (Neutral) position
1. Start the engine as instructed in “How to start the
engine” on page 388.
The transmission must be in “P” or “N” position. The engine wi\
ll
not start in any drive position even if the ignition key is turned
to “START”.

STARTING AND DRIVING
400
1Brake pedal 2 “D” (Drive) position
2. With your foot holding down the brake pedal, shift the
selector lever to “D” position.
Always use the “D” position to improve fuel economy and quiet
driving. 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.
3. Release the parking brake and brake pedal. Depress
the accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in first gear and
automatically shift up to the most suitable gear. On inclines,
declines or winding roads, etc., the vehicle shifts up and down
automatically according to the running conditions to obtain the
suitable driving power and engine braking.
If you need to accelerate rapidly while driving, depress the
accelerator pedal to the full throttle position. This provides
more acceleration by automatically downshifting the
transmission to the next lower gear or beyond, depending on
the vehicle speed.
If engine braking is needed, such as in descending a long hill,
see “(c) Using engine braking”.

STARTING AND DRIVING
402“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 51 (32)
2 92 (58)
3 144 (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.

STARTING AND DRIVING
403
(c) Using engine braking
“S” mode position
To use the braking power of the engine, downshift the range in
the “S” mode position as follows:
 Shift into the “4” (fourth range) position. The transmission
will downshift to fourth gear and engine braking will be
engaged.
If you drive in the “D” position: Shift the selector lever to
the “S” position and “4” (fourth range) will automatically\
be
selected.
If you drive in the “S” position: Shift the selector lever
down to the “ −” position by selecting the “4” (fourth range). Vehicles with the cruise control —
When
the cruise control is being used, even if you downshift
from “D” or “5” (fifth range) to “4” (fourth range)\
, engine
braking will not be enabled because the cruise control is not
cancelled. For vehicle speed reduction, see page 415.
Vehicles with the dynamic 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 “5” (fifth range) to “4” (fourth range),
engine braking will not be enabled because the cruise
control is not cancelled. For vehicle speed reduction, see
pages 427 and 436.
 Shift into the “3” (third range) position. The transmission will
downshift to third gear when the vehicle speed is or
becomes lower than 129 km/h (81 mph) and more powerful
engine braking will be enabled.
If you drive in the “D” position: Shift the selector lever to
the “S” position then shift the lever down to the “ −” position
once to select the “3” (third range).
If you drive in the “S” position: Shift the selector lever
down to the “ −” position to select “3” (third range).

STARTING AND DRIVING
404
Shift into the “2” (second range) position. The transmission
will downshift to second gear when the vehicle speed is or
becomes lower than 83 km/h (52 mph) and more powerful
engine braking than that of the “3” (third range) position 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 “ −” position
twice to select “2” (second range).
If you drive in the “S” position: Shift the selector lever
down to the “− ” position to select “2” (second range).
 Shift into the “1” (first range) position. The transmission will
downshift to first gear when the vehicle speed is or becomes
lower than 39 km/h (24 mph) and maximum 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 “ −” position
three times to select “1” (first range).
If you drive in the “S” position: Shift the selector lever
down to the “− ” position to select “1” (first range).
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to skid or spin.

STARTING AND DRIVING
407
(f) Good driving practice
If the transmission repeatedly shifts up and down between
fourth and overdrive gears when climbing a gentle slope,
shift the selector lever into the “S” position. Be sure to shift
the selector lever to the “D” position after climbing the slope.
 When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive (fifth) gear.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or the parking brake to hold
the vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.
(g) If you cannot shift the selector lever
If you cannot shift the selector lever even though the brake
pedal is depressed, use the shift lock override button. For
instructions, see “If you cannot shift automatic transmission
selector lever” on page 524.
