check engine lexus LS400 1994 Gauges, Meters and Service Reminder Indicators / 1994 LS400: DRIVING TIPS

DRIVING TIPS
140
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 “P”. 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
pressed. 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
141
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 126.

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 over 140 km / h (85 mph) unless your
vehicle has high-speed capability tires, regardless of
the legal speed limit. 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 222 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 199 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
142Use 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 “P” 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 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.
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
145
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. Refer to the
maintenance schedule under severe driving conditions
(Schedule A) in Section 5 for specific information.
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 may
not shift.

Check that your rear view mirrors conform to any federal,
state / provincial or local regulation. If not, install required
rear view mirrors 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 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.

DRIVING TIPS
147
Always place wheel blocks under both the vehicle and trailer
wheels when parking. Apply the parking brake firmly. Put
the transmission in “P”. Avoid parking on a slope with a
trailer, but if it cannot be avoided, do so only after performing
the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks under both the vehicle
and trailer wheels.
3. When the wheel blocks are in place, release your brakes
slowly until the blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into “P” and turn off the engine.
When restarting out after parking on a slope:
1. With the transmission in “P” position, start the engine. Be
sure to keep the brake pedal depressed.
2. Shift into the “2”, “L” or “R” position.
3. Release the parking brake and brake pedal and slowly pull
or back away from the wheel blocks. Stop and apply your
brakes.
4. Have someone retrieve the blocks.
CAUTION:

Do not exceed 72 km / h (45 mph) or the posted towing
speed limit, whichever is lower. Because instability
(swaying) of a towing vehicle-trailer combination
usually increases as the speed increases, exceeding 72
km / h (45 mph) may cause loss of control.
Slow down and downshift before descending steep or
long downhill grades. Do not make sudden downshifts.

Avoid holding the brake pedal down too long or too
frequently. This could cause the brakes to overheat and
result in reduced braking efficiency.
HOW TO SAVE FUEL AND MAKE
YOUR VEHICLE LAST LONGER
Getting more kilometers / 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.
