check engine lexus LS400 1996 Engine / 1996 LS400: DRIVING TIPS

DRIVING TIPS
148
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 number).
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 ªPº. 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 off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.

DRIVING TIPS
149
Do not rest your foot on the brake pedal while
driving. It can cause dangerous overheating,
needless wear, and poor fuel economy.
To drive down a long or steep hill, reduce your
speed and downshift. Remember, if you ride the
brakes excessively, they may overheat and not work
properly. See page 134.
Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to spin or skid.
Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140
km/h (85 mph) unless your vehicle has high±speed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are high±speed
capability tires or not before driving at such speeds.
Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.
WINTER DRIVING TIPS
Make sure you have ethylene±glycol antifreeze in the
radiator.
NOTICE
Do not use alcohol type antifreeze.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it
must be in top shape to provide enough power for winter
starting. Page 216 tells you how to visually inspect the
battery. Your Lexus dealer and most service stations will be
pleased to check the battery charge level.
Make sure the engine oil viscosity is suitable for the
cold weather.
See page 196 for recommended viscosity. Leaving a heavy
summer oil in your vehicle during winter months may cause
harder starting. If you are not sure about which oil to use, call
your Lexus dealer ± they will be pleased to help.
Check the electronic ignition system/distributor
ignition system for loose connections or obvious
damage.
Keep the door locks from freezing.
Squirt lock de±icer or glycerine into the locks to keep them
from freezing. To open a frozen lock, try heating the key
before inserting it.

DRIVING TIPS
150Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto
parts stores. Follow the manufacturer's directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute
because it may damage your vehicle's paint.
Do not use your parking brake when there is a
possibility it could freeze.
When parking, put the transmission into ªPº and block the
front wheels. Do not use the parking brake, or snow or water
accumulated in and around the parking brake mechanism
may freeze the parking brake, making it hard to release.
Keep ice and snow from accumulating under the
fenders.
Ice and snow built up under your fenders can make steering
difficult. During bad winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving, we recommend
you carry some emergency equipment.
Some of the things you might put in the vehicle are tire
chains, window scraper, bag of sand or salt, flares, small
shovel, jumper cables, etc.
TRAILER TOWING
Your vehicle is designed primarily as a passenger±carrying
vehicle. Towing a trailer will have an adverse effect on
handling, performance, braking, durability and driving
economy (fuel consumption, etc.). Your safety and
satisfaction depend on the proper use of correct equipment
and cautious driving habits. For your safety and the safety
of others, you must not overload your vehicle or trailer. Lexus
warranties do not apply to damage or malfunction caused by
towing a trailer for commercial purposes. Ask your local
Lexus dealer for further details before towing.
NOTICE
When towing a trailer, be sure to consult your Lexus
dealer for further information on additional
requirements.
Weight limits
Before towing, make sure the total trailer weight, gross
vehicle weight, gross axle weight and trailer tongue
load are all within the limits.
The total trailer weight and tongue load can be measured
with platform scales found at a highway weighing station,
building supply company, trucking company, junk yard, etc.

DRIVING TIPS
153
Tires

Ensure that your vehicle's tires are properly inflated. Adjust
the tire pressure to the recommended cold tire pressure
indicated below:
Tire pressure, kPa (kgf/cm
2 or bar, psi)
Front 220 (2.2, 32)
Rear 220 (2.2, 32)
The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect to the
total trailer weight.
Trailer lights

Trailer lights must comply with federal, state/provincial and
local regulations. See your local recreational vehicle dealer
or rental agency for the correct type of wiring and relays for
your trailer. Check for correct operation of the turn signals
and stop lights each time you hitch up. Direct splicing may
damage your vehicle's electrical system and cause a
malfunction of your lights.
Break±in schedule

Lexus recommends that you do not tow a trailer with a new
vehicle or a vehicle with any new power train component
(engine, transmission, differential, wheel bearing, etc.) for
the first 800 km (500 miles) of driving.
Maintenance

If you tow a trailer, your vehicle will require more frequent
maintenance due to the additional load. For this
information, please refer to the scheduled maintenance
information in the ªOwner's Manual Supplement/
Maintenance Scheduleº.
Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Pre±towing safety check

Check that your vehicle remains level when a loaded or
unloaded trailer is hitched. Do not drive if the vehicle has
an abnormal nose±up or nose±down condition, and check
for improper tongue load, overload, worn suspension or
other possible causes.
Make sure the trailer cargo is securely loaded so that it
cannot shift.
Check that your rear view mirrors conform to any federal,
state/provincial or local regulation. If they do not, install
required rear view mirrors appropriate for towing purposes.

Trailer towing tips
When towing a trailer, your vehicle will handle
differently than when not towing. The three main
causes of vehicle±trailer accidents are driver error,
excessive speed and improper trailer loading. Keep
these in mind when towing:
Before starting out, check the operation of the lights and all
vehicle±trailer connections. After driving a short distance,
stop and recheck the lights and connections. Practice
turning, stopping and backing with a trailer in an area away
from traffic until you learn the feel.
Backing with a trailer is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the
right to move the trailer to the right. (This procedure is
generally opposite to that when backing without a trailer.)
Also, just turn the steering wheel a little at a time, avoiding
sharp or prolonged turning. Have someone guide you
when backing to reduce the risk of an accident.
Because stopping distance may be increased,
vehicle±to±vehicle distance should be increased when
towing a trailer. For each 16 km/h (10 mph) of speed, allow
at least one vehicle and trailer length between you and the
vehicle ahead. Avoid sudden braking as you may skid,
resulting in jackknifing and loss of control. This is especially
true on wet or slippery surfaces.
Avoid jerky starts or sudden acceleration.
Avoid jerky steering and sharp turns. The trailer could hit
your vehicle in a tight turn. Slow down before making a turn
to avoid the need of sudden braking.
Remember that when making a turn, the trailer wheels will
be closer than the vehicle wheels to the inside of the turn.
Therefore, compensate for this by making a larger than
normal turning radius with your vehicle.
Crosswinds and rough roads will adversely affect handling
of your vehicle and trailer, causing sway. Pay attention to
the rear from time to time to prepare yourself for being
passed by large trucks or buses, which may cause your
vehicle and trailer to sway. If swaying happens, firmly grip
the steering wheel and reduce speed immediately but
gradually. Never increase speed. If it is necessary to
reduce speed, brake slowly. Steer straight ahead. If you
make no extreme correction with the steering or brakes,
your vehicle and trailer will stabilize.
Be careful when passing other vehicles. Passing requires
considerable distance. After passing a vehicle, do not
forget the length of your trailer and be sure you have plenty
of room before changing lanes.
In order to maintain efficient engine braking and electrical
charging performance, do not use overdrive. Transmission
must be in the ª3º position.

HOW TO SAVE FUEL AND MAKE
YOUR VEHICLE LAST LONGER
Getting more kilometer/mileage from a liter/gallon of fuel is
easy ± just take it easy. It will help make your vehicle last
longer, too. Here are some specific tips on how to save
money on both fuel and repairs:
Keep your tires inflated at the correct pressure. Check
the pressure every two weeks, or at least once a month.
Underinflation causes tire wear and wastes fuel.
Do not carry unneeded weight in your vehicle. Excess
weight puts a heavier load on the engine, causing greater
fuel consumption.
Avoid lengthy warm±up idling. Once the engine is
running smoothly, begin driving ± but gently. Remember,
however, that on cold winter days this may take a little
longer.
Accelerate slowly and smoothly. Avoid jackrabbit starts.
Avoid long engine idling. If you have a long wait and you
are not in traffic, it is better to turn off the engine and start
again later.
Avoid engine overrevving. Use a gear position suitable
for the road on which you are traveling.
Avoid continuous speeding up and slowing down.
Stop±and±go driving wastes fuel.
Avoid unnecessary stopping and braking. Maintain a
steady pace. Try to time traffic signals so you only need to
stop as little as possible or take advantage of through
streets to avoid traffic lights. Keep a proper distance from
other vehicles to avoid sudden braking. This will also
reduce wear on your brakes.
Avoid heavy traffic or traffic jams whenever possible.
Do not rest your foot on the brake pedal. This causes
needless wear, overheating and poor fuel economy.
Maintain a moderate speed on highways. The faster
you drive, the greater the fuel consumption. By reducing
your speed, you will cut down on fuel consumption.
Keep the front wheels in proper alignment. Avoid
hitting the curb and slow down on rough roads. Improper
alignment not only causes faster tire wear but also puts an
extra load on the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free from mud, etc.
This not only lessens weight but also helps prevent
corrosion.
Keep your vehicle tuned±up and in top shape. A dirty
air cleaner, improper valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc. all lower engine
performance and contribute to poor fuel economy. For
longer life of all parts and lower operating costs, keep all
maintenance work on schedule, and if you often drive
under severe conditions, see that your vehicle receives
more frequent maintenance. (For scheduled maintenance
information, please refer to the separate ªOwner's Manual
Supplement/Maintenance Scheduleº.)
