STARTING AND DRIVING

5. Release the parking brake and brake pedal. Depress
the accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in the 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.
When the lever is in º3º position, the automatic transmission
system will select the most suitable gear for the running
conditions such as hill climbing, hard towing, etc.
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 º(b) Using engine brakingº.
(b) Driving in M mode
If the change lever is shifted to M position, the shift range
position can be switched over between 5 and 2 using the
shift switch on the steering wheel instead of operating the
change lever. The first shift range position is on 5 when
the change lever is shifted to M position.

1ºMº position
When the selector lever is put in the ºMº position, the M MODE
indicator is shown on the instrument cluster.

3Shift into the º2º position. The transmission will downshift
to second gear when the vehicle speed is or becomes
lower than the speed listed below and stronger engine
braking than that of º3º position will be obtained.
4Shift into the ºLº position. The transmission will downshift
to first gear when the vehicle speed is or becomes lower
than the speed listed below and maximum engine braking
will be enabled.
º4º 177 km/h (110 mph)
º3º 123 km/h (76 mph)
º2º 81 km/h (51 mph)
ºLº 17 km/h (11 mph)
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to spin or skid.
(d) Using the º3º, º2º and ºLº positions
The º3º, º2º and ºLº positions are used for strong eng\
ine
braking as described previously.
With the selector lever in º3º, º2º or ºLº, you can start t\
he vehicle
in motion as with the lever in ºDº.
With the selector lever in º3º or º2º, the vehicle will star\
t in the
first gear and automatically shift to third or second gear.
With the selector lever in ºLº, the transmission is engaged in
the first gear.
NOTICE
Be careful not to over±rev the engine. Watch the tachometer to keep engine rpm from going into thered zone. The approximate maximum allowablespeed for each position is given below for yourreference:
º3º 124 km/h (78 mph)
. . . . . . . . . . . . . . . . . . .
º2º 81 km/h (51 mph)
. . . . . . . . . . . . . . . . . . .
ºLº 52 km/h (33 mph)
. . . . . . . . . . . . . . . . . . .
Do not continue hill climbing or hard towing for a long
time in the º3º, º2º or ºLº position. This may causesevere automatic transmission damage from
overheating. To prevent such damage, º4º positionshould be used in hill climbing or hard towing.

STARTING AND DRIVING
240Good driving practice
If it is difficult to shift into reverse, put the transmission in
neutral, release the clutch pedal momentarily, and then try
again.
When towing a trailer, in order to maintain engine braking
efficiency, do not use fifth gear.
CAUTION
Be careful when downshifting on a slippery surface.
Abrupt shifting could cause the vehicle to spin or skid.
NOTICE
Make sure the vehicle is completely stopped before
shifting into reverse.
ELECTRONIC CONTROLLED TRANSMISSION
(Vehicle with automatic transmission only)
SV31039
1Power position 2Normal position
The electronic controlled system has 2 modes: Normal
and Power modes.
Normal mode: For ordinary driving, Lexus recommends that
you use the normal mode to improve fuel economy.
Power mode: For more powerful acceleration and sporty
driving.
In the power mode, the ºECT PWRº 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
mode.
