stop start LEXUS SC300 1999 User Guide

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
237
(d) Backing up
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.

(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 º3º 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 º3º position.

Traction control failure warning
If the ºTRAC OFFº 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 traction of the
vehicle and power to the rear wheels cannot be maintained,
even though the traction control system is in operation. Do not
drive the vehicle under any speed or maneuvering conditions
which will cause the vehicle to lose traction. In situations
where the road surface is covered with ice or snow, your
vehicle should be fitted with snow tires or tire chains. Always
drive at an appropriate and 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.

STARTING AND DRIVING
249
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
250
Anti±lock brake system
The anti±lock brake system is designed to automatically
help prevent lock±up 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 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.
Effective way to press the ABS brake pedal: 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 in a panic stop. Pumping the
brake pedal makes the stopping distance longer.

STARTING AND DRIVING
251
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
vehicle 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 not 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.

DRIVING TIPS
259
BREAK±IN PERIOD
Drive gently and avoid high speeds.
You need not follow a break±in schedule with your new
Lexus. But following a few simple tips for the first 1600 km
(1000 miles) can add to the future economy and long life of
your vehicle:

Do not drive over 88 km/h (55 mph).

Avoid overrevving. Maintain engine speed between 2000
and 4000 rpm.

Avoid full±throttle starts.

Try to avoid hard stops during the first 300 km (200 miles).

Do not drive for a long time at any single speed, either fast
or slow.

Do not tow a trailer during the first 800 km (500 miles).
OPERATION IN FOREIGN
COUNTRIES
If you plan to drive your Lexus in another country ...
First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel (unleaded
and minimum octane rating).
TIPS FOR DRIVING IN VARIOUS CONDITIONS

Always slow down in gusty crosswinds. This will allow
you much better control.

Drive slowly onto curbs and, if possible, at a right angle.
Avoid driving onto high, sharp±edged objects and other
road hazards. Failure to do so can lead to severe tire
damage resulting in tire bursts.

When parking on a hill, turn the front wheels until they
touch the curb so that the vehicle will not roll. Apply the
parking brake, and place the transmission in ºPº. If
necessary, block the wheels.

Washing your vehicle or driving through deep water may
get the brakes wet. To see whether they are wet, check that
there is no traffic near you and then press the pedal lightly.
If you do not feel a normal braking force, the brakes are
probably wet. To dry them, drive the vehicle cautiously
while lightly pressing the brake pedal with the parking
brake applied. If they still do not work safely, pull to the
side of the road and call a Lexus dealer for assistance.
CAUTION

Before driving, make sure the parking brake is fully
released and that the parking brake reminder light is off.
