stop start lexus LS400 1995 Engine / 1995 LS400: STARTING AND DRIVING

STARTING AND DRIVING
135
(c) Backing up
 1
“R” (Reverse) position 2
Brake pedal
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.
(d) Parking
 1
“P” (Park) position 2
Brake pedal
3
Parking brake pedal
1. Bring the vehicle to a complete stop.
2. Depress the parking brake pedal fully.
3. With the brake pedal held down with your foot, shift the
selector lever to the “P” position.
CAUTION
While the vehicle is moving, never attempt to move the
selector lever into “P” under any circumstances.
Serious mechanical damage and loss of vehicle control
may result.

(e) 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 “3” 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 “3” 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.
(f) If you cannot shift the selector lever
If you cannot shift the selector ever 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 175.
(g) If the “ECT PWR” indicator light flashes
If the “ECI PWR” indicator light flashes, contact your Lexus
dealer as soon as possible. There may be trouble in the
transmission system.
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 cruse control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.

Traction control failure warning
If the “TRAC OFF” indicator / warning light flashes, contact
your Lexus dealer as soon as possible. There may be trouble
in the traction control system.
CAUTION
Under certain slippery road conditions, full stability of
the vehicle and power to the rear wheels cannot be
maintained, even though the traction control system is
in operation. In situations where the road surface is
covered with ice or snow, your vehicle should be fitted
with snow tires or tire chains and driven at a more
cautious pace.
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic
system with two separate sub−systems. If either sub−system
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 power−assist 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
143
Anti−lock brake system
The anti−lock brake system is designed to prevent
lock−up of the wheels during sudden braking or braking
on slippery road surfaces. This assists the driver in
controlling the vehicle under these circumstances.
The anti−lock 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 anti−lock brake system is in the
self check mode, and does not indicate a malfunction.
When the anti−lock brake system function is in action, you may
feel the brake pedal pulsating and hear a noise. In this
situation, to let the anti−lock brake system work for you, just
hold the brake pedal down more firmly. Do not pump the brake.
The brake pedal pulsation caused by the anti−lock brake
system may indicate hazardous road surface conditions.
Although the anti−lock brake system assists in providing
vehicles control, it is still important to drive with all due care,
because the anti−lock 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 anti−lock 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 anti−lock 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 riot fitted with an anti−lock brake
system, your vehicle may require a longer stopping distance
in the following cases:

Driving on rough, gravel or snow−covered roads.

Driving with tire chains installed.

Driving on roads where the road surface is pitted or has
other differences in surface height.
