1999 LEXUS SC300 Owners Manual

STARTING AND DRIVING
223
To use the braking power of the engine, downshift the
transmission in the way described below:
1
Shift into the º4º position. The transmission will
downshift to the fourth gear and engine braking will be
obtained.
When the cruise control is being used, even if you
downshift from ºDº to º4º, engine braking will not be
applied because the cruise control is not cancelled. If
you need to decrease the vehicle speed, see page 245.
2Shift into the º3º position. The transmission will
downshift to the third gear when the vehicle speed is or
becomes lower than 149 km/h (93 mph) and more
powerful engine braking will be obtained.
3Shift into the º2º position. The transmission will
downshift to the second gear when the vehicle speed is
or becomes lower than 97 km/h (61 mph) and more
powerful engine braking than that of º3º position will
be obtained.
4Shift into the ºLº position. The transmission will
downshift to the first gear when the vehicle speed is or
becomes lower than 18 km/h (11 mph) and maximum
engine braking will be applied.
CAUTION
Be careful when downshifting on a slippery surface. The
abrupt change in engine speed could cause the vehicle to spin
or skid.

STARTING AND DRIVING
224
(c) Using the º3º, º2º and ºLº positions
The º3º, º2º and ºLº positions are used for strong engine\
braking as described previously.
With the selector lever in º3º, º2º or ºLº, you can sta\
rt the
vehicle in motion as with the lever in ºDº.
With the selector lever in º3º or º2º, the vehicle will start in
the first gear and automatically shift to the third or second
gear.
With the selector lever in ºLº, the transmission is engaged in
the 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:
º3º 153 km/h (96 mph) . . . .
º2º 100 km/h (63 mph) . . . .
ºLº 65 km/h (41 mph) . . . .
 Do not continue hill climbing or hard towing for a long
time in the º3º, º2º or ºLº position. This may cause
severe automatic transmission damage from
overheating. To prevent such damage, º4º position
should be used in hill climbing or hard towing.
(d) Backing up

STARTING AND DRIVING
225
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the
selector lever to the ºRº position.
NOTICE
Never shift into reverse while the vehicle is moving.

STARTING AND DRIVING
226
(e) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever up fully to securely apply the
parking brake.
3. With the brake pedal held down with your foot, shift the
selector lever to the ºPº position.
CAUTION
While the vehicle is moving, never attempt to move the
selector lever into ºPº under any circumstances. Serious
mechanical damage and loss of vehicle control may result.

STARTING AND DRIVING
227
(f) Good driving practice
If the transmission repeatedly upshifts and downshifts
between the fourth and overdrive gears when climbing a
gentle slope, shift the selector lever to the º4º position. Be
sure to shift the selector lever to the ºDº position after
climbing the slope.
 When towing a trailer, in order to maintain ef ficient engine
braking and electrical charging performance, do not use
overdrive. The selector lever must be in the º4º position.
CAUTION
Always keep your foot on the brake pedal while stopped with
the engine running. This prevents the vehicle from creeping.
NOTICE
Do not hold the vehicle on an upgrade with the
accelerator pedal. This can cause the transmission to
overheat. Always use the brake pedal or parking brake.
(g) Rocking your vehicle if stuck
CAUTION
If your vehicle becomes stuck in snow, mud, sand, etc., then
you may attempt to rock the vehicle free by moving it forward
and backward. Do not attempt this procedure if people or
objects are anywhere near the vehicle. During the rocking
operation the vehicle may suddenly move forward or back as
it becomes un±stuck, causing injury or damage to nearby
people or objects.

STARTING AND DRIVING
228
NOTICE
If you rock your vehicle, observe the following
precautions to prevent damage to the transmission and
other parts.
Do not depress the accelerator pedal while shifting the
selector lever or before the transmission is completely
shifted to forward or reverse gear.
 Do not race the engine and avoid spinning the wheels.
 If your vehicle remains stuck after rocking the vehicle
several times, consider other ways such as towing.
(h) 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 ºIf you cannot shift automatic transmission
selector leverº on page 306.

STARTING AND DRIVING
229
AUTOMATIC TRANSMISSION(SC300)
Your automatic transmission has a shift lock system to
minimize the possibility of incorrect operation. This
means you can only shift out of ºPº position when the
brake pedal is depressed with the ignition switch in ºONº
position. ()

STARTING AND DRIVING

The shift position is displayed on the instrument cluster.
P: Parking, engine starting and key removal position
R: Reverse position
N: Neutral position
D: Normal driving position (Shifting into overdrive
possible)
3: Position for engine braking (Shifting into overdrive
not possible)
When the cruise control is being used, even if you
downshift from ºDº to º3º, engine braking will not be
applied because the cruise control is not cancelled. For
the operation to decrease the vehicle speed, see page
245.
2: Position for more powerful engine braking
L: Position for maximum engine braking Correct use of the automatic transmission is explained in
the following parts.
(a) Normal driving
(b) Using engine braking
(c) Using the º2º and ºLº positions
(d) Backing up
(e) Parking
(f) Good driving practice
