set lexus LS400 1996 Gauges, Meters and Service Reminders / 1996 LS400: STARTING AND DRIVING

STARTING AND DRIVING
129 If you leave the key in the ªACCº or ªLOCKº position and
open the driver's door, a buzzer will remind you to remove
the key.
ªLOCKº ± Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the key from ªACCº to the ªLOCKº position, you must
put the transmission selector lever in the ªPº position.
When starting the engine, the key may seem stuck at the
ªLOCKº position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to ªACCº.
PARKING BRAKE

To set: Fully depress the parking brake pedal.
To release: Pull the parking brake release lever.
Before leaving your vehicle, firmly apply the parking brake.
CAUTION!
Before driving, make sure the parking brake is fully
released and that the parking brake reminder light is
off.

STARTING AND DRIVING
132
(a) Normal driving

ªPº (Park) positionªNº (Neutral) position
1. Start the engine as instructed in ªHow to start the
engineº on page 130.
The transmission must be in ªPº or ªNº. The engine will not
start in any drive position even if the ignition key is turned to
ªSTARTº.

Driving pattern selector switch
Normal positionPower position
2. Set the driving pattern selector switch to the
NORMAL position.
Your transmission has a driving pattern selector switch
which allows you to select either ªNORMº or ªPWRº 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 ªECT 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 position.

STARTING AND DRIVING
136
(f) Good driving practice

If the transmission repeatedly upshifts and downshifts
between the third and overdrive gears when climbing a
gentle slope, shift the selector lever to the ª3º position. Be
sure to shift the selector lever to the ªDº position after
climbing the slope.
When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive. The selector lever must be in the ª3º 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) 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 ªIf you cannot shift automatic transmission
selector leverº on page 175.
CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over 40 km/h (25 mph) with your foot off
the accelerator pedal.
Your cruising speed can be maintained although a slight
speed change may occur when driving up or down a
gradient, within the limits of engine performance. On steeper
hills, a great speed change will occur so it is better to drive
without the cruise control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.
CAUTION!

To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snow±covered) or winding roads.
Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation
to the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.

STARTING AND DRIVING

Turning on the system
To operate the cruise control, push the main switch. This
turns the system on. The indicator light in the instrument
cluster shows that you can now set your desired cruising
speed. Another push on the switch will turn the system
completely off.
When the ignition key is turned off, the main switch is also
automatically turned off. To use the cruise control again,
push the main switch again to turn it on.
CAUTION!
To avoid accidental cruise control engagement,
keep the main switch off when not using the cruise
control.
Setting at a desired speed
The transmission must be in ªDº or ª3º before you set the
cruise control speed.
Bring the vehicle to the desired speed, press the control
lever downward in the ªSET/COASTº direction and release
it. This sets the vehicle at that speed. Now you may take your
foot off the accelerator pedal. If you need acceleration ± for
example, when passing ± depress the accelerator pedal
enough for the vehicle to exceed the set speed. When you
release the accelerator pedal, the vehicle will return to the
speed set prior to the acceleration.
Cancelling the preset speed
You can cancel the preset speed by either of the following:
a. Pulling the control lever in the ªCANCELº direction.
b. Depressing the brake pedal.

STARTING AND DRIVING
138If the vehicle speed falls below about 40 km/h (25 mph), the
preset speed will be automatically cancelled.
If the vehicle speed drops 16 km/h (10 mph) below the preset
speed, the preset speed will also automatically be cancelled.
If the preset speed automatically cancels out for other than
these reasons, have your vehicle checked by your Lexus
dealer at the earliest opportunity.
Resetting to a faster speed
Press the control lever upward in the ªRES/ACCº direction
and hold it. Release the lever when the desired speed is
attained. While the lever is held upward, the vehicle will
gradually gain speed.
When the difference between the actual vehicle speed and
the set speed is less than 5 km/h (3 mph), the set speed can
be increased 1.6 km/h (1 mph) each time by pressing the
control lever upward in the ªRES/ACCº direction quickly
within 0.6 seconds.
However, a quicker way to reset is to accelerate the vehicle
and then press the control lever downward in the
ªSET/COASTº direction.
Resetting to a slower speed
Press the control lever downward in the ªSET/COASTº
direction and hold it. Release the lever when the desired
speed is attained. While the lever is held downward, the
vehicle speed will gradually decrease.
When the difference between the actual vehicle speed and
the set speed is less than 5 km/h (3 mph), the set speed can
be lowered 1.6 km/h (1 mph) each time by pressing the
control lever downward in the ªSET/COASTº direction
quickly within 0.6 seconds.
However, a quicker way to reset is to depress the brake
pedal and then press the control lever downward in the
ªSET/COASTº direction.
Even if you downshift the transmission from the ªDº position
to ª3º with the cruise control on, engine braking will not be
applied because the cruise control is not cancelled. To
decrease the vehicle speed, reset to a slower speed with the
cruise control lever or depress the brake pedal. If you use the
brake pedal, cruise control is cancelled.
Resuming the preset speed
If the preset speed is cancelled by pulling the control lever
or by depressing the brake pedal, pushing the lever up in the
ªRES/ACCº direction will restore the speed set prior to
cancellation. However, once the vehicle speed falls below
about 40 km/h (25 mph), the preset speed will not be
resumed.

STARTING AND DRIVING
140ªNORMALº mode ± For driving on roads with a normal
surface.
ªHIGHº mode ± For driving on rough roads which are
unsurfaced or continually bumpy.
The damping effect is set slightly firmer in ªHIGHº mode. So
you may feel the vibration of the vehicle compared to in
ªNORMALº mode. However, this does not mean a
malfunction in the system. We recommend you use a
ªNORMALº mode in normal driving.
To change the mode, push the selector switch.
ªNORMALº mode
The vehicle height remains at normal height at all driving
speeds.
ªHIGHº mode
The vehicle height switches between the following two
vehicle heights according to the driving conditions:
Vehicle height
Driving condition
NormalMedium and high speed driving
HighLow speed driving
The indicator light shows ªHIGHº mode is selected.
When you turn the ignition key to the ªONº position, the
indicator light will come on for 2 seconds in any mode.
NOTICE
For vehicles equipped with the height control switch,
be sure to turn the ignition switch off before jacking.
If this is not done, the vehicle height adjustment
function will operate, which may cause body
damage.
(b) Malfunction warning
If the ªHIº indicator light blinks, there is a malfunction in this
system. Have the system checked by your Lexus dealer at
the first opportunity.
