1998 Lexus LS400 stop start

COMFORT ADJUSTMENT
114The beep sound means that the positions are recorded in the
computer ’s memory.
By repeating these two steps and pressing the remaining button, the
driving position for another driver can be recorded.
To set a new memorized position, select the desired position and
perform step 2. The previous memory will be erased and the new
position will be set.
To make only slight changes to an already memorized position, the
easiest way is to first activate the memorized position, then make the
desired changes and perform step 2 above.
Activating a memorized position
16L056
When you push button ”1” or ”2”, the driving position will be
automatically adjusted to the position recorded for that button.Conditions for memorized position activation
Ignition key ”ON” and shift lever in ”P” position.
All parts of the memorized positions can be activated.
However, if the brake pedal is being depressed, the seat position
will not change.
Key not in ignition switch and within 30 seconds of opening
driver’s door.
The memorized position can be activated, except for the tilt and
telescopic steering.
If any driving position memory switch is pushed while one of the
memorized driving position profiles is being activated, the operation
will stop.
To activate the system, push the desired button (”1” or ”2”) again.
The driving position memory control system cannot be operated
while the vehicle is moving.
If the vehicle’s battery is disconnected, the computer’s memory will
be erased and the memorized positions will have to be set again.
CAUTION
Do not start the vehicle while the adjustments are being
made.
Take care not to select the wrong button, or the seat could
strike the rear passenger or hit your body against the
steering wheel. If this happens, you can stop the movement
by pressing another driving position memory switch, or
depressing the brake pedal.

(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 ”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. The selector lever must be in the ”4” 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 unstuck, causing injury or damage to nearby
people or objects.
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.

STARTING AND DRIVING
176
CAUTION
Do not rely excessively on the vehicle skid control system.
Even if the vehicle skid control system is operating, it is not
that your vehicle is absolutely safe. Reckless driving will
result in an unexpected accident. Always keep safety
driving in mind. If the slip indicator light flashes, sounding
an alarm, special care should be taken while driving.
Only use tires of specified size. The size, manufacturer,
brand and tread pattern for all 4 tires should be the same.
If you use the tires other than specified, or different type or
size, the vehicle skid control system may not function
correctly. When replacing the tires or wheels, contact your
Lexus dealer.
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic system with
two separate subsystems. If either subsystem should fail, the other
will still work. However, the pedal will be harder to press, and your
stopping distance will be longer. Also, the brake system warning
light may come on.
CAUTION
Do not drive your vehicle with only a single brake system.
Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to powerassist the brakes.
If the engine should quit while you are driving, you can bring the
vehicle to a stop with normal pedal pressure. There is enough
reserve vacuum for one or two stops but no more!
CAUTION
Do not pump the brake pedal if the engine stalls. Each push
on the pedal uses up your vacuum reserve.
Even if the power assist is completely lost, the brakes will
still work. But you will have to push the pedal hard much
harder than normal. And your braking distance will be
longer.

STARTING AND DRIVING
177
Antilock brake system
The antilock brake system is designed to automatically help
prevent lockup of the wheels during a sudden brake or braking
on slippery road surfaces. This assists in providing directional
stability and steering performance of the vehicle under these
circumstances.
The antilock brake system becomes operative after the vehicle has
accelerated to a speed in excess of approximately 10 km/h (6 mph).
It stops operating when the vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
You may hear a sound in the engine compartment for a few seconds
when the engine is started or just after the vehicle is started. This
means that the antilock brake system is in the selfcheck mode, and
does not indicate a malfunction.
Effective way to press the ABS brake pedal: When the antilock
brake system function is in action, you may feel the brake pedal
pulsating and hear a noise. In this situation, to let the antilock brake
system work for you, just hold the brake pedal down more firmly.
Do not pump the brake. This will result in reduced braking
performance.
The brake pedal pulsation caused by the antilock brake system may
indicate hazardous road surface conditions. Although the antilock
brake system assists in providing vehicle control, it is still important
to drive with all due care, because the antilock brake system cannot
overcome the laws of physics that act on your vehicle:
Braking capability is dependent on tire friction with the road
surface.Even though the antilock brake system is operating, a driver
cannot maintain full control on certain slippery road surfaces,
when cornering at high speeds, or in violent maneuvers.
Avoid high speeds on wet roads. The antilock brake system
cannot eliminate the risk of hydroplaning and loss of tire friction.
Always maintain a safe distance from the vehicle in front of you.
Compared with vehicles not fitted with an antilock brake system,
your vehicle may require a longer stopping distance in the following
cases:
Driving on rough, gravel or snowcovered roads.
Driving with tire chains installed.
Driving on roads where the road surface is pitted or has other
differences in surface height.
