1994 Lexus LS400 weight

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
143
Certification label
CAUTION:

The total trailer weight (trailer weight plus its cargo
load) must not exceed 907 kg (2000 lb.). Exceeding this
weight is dangerous.

The gross vehicle weight must not exceed the Gross
Vehicle Weight Rating (GVWR) indicated on the
Certification Label. The gross vehicle weight is the sum
weight of the unloaded vehicle, driver, passengers,
luggage, hitch and trailer tongue load. It also includes
the weight of any special equipment installed on your
vehicle.

The load on either the front or rear axle resulting from
distribution of the gross vehicle weight on both axles
must not exceed the Gross Axle Weight Rating (GAWR)
listed on the Certification Label.
Total trailer weightTongue load
x 100 = 9 to 11 %Total trailer weightTongue load

The trailer cargo load should be distributed so that the
tongue load is 9 to 11 % of the total trailer weight, not
exceeding the maximum of 90 kg (200 lb.). Never load
the trailer with more weight in the back than in the front.
About 60 % of the trailer load should be in the front half
of the trailer and the remaining 40 % in the rear.
Hitches

Use only a hitch which is recommended by the hitch
manufacturer and conforms to the total trailer weight
requirement.

Follow the directions supplied by the hitch manufacturer,
and bolt the hitch securely to the rear bumper. Lubricate the
hitch ball with a light coat of grease.

DRIVING TIPS
144
Lexus recommends removing the trailer hitch whenever
you are not towing a trailer to reduce the possibility of
additional damage caused by the hitch if your vehicle is
struck from behind. After removing the hitch, seal any
mounting holes in the vehicle body to prevent entry of
pollutants such as exhaust fumes, dirt, water, etc.
CAUTION:
The rear bumper reinforcement is made of aluminum, so
do not allow steel hitch parts to come in direct contact
with it. When steel and aluminum are in contact, a galvanic
reaction (electrolytic corrosion) occurs which can
weaken the strength of the contacting parts and cause
damage. When installing a steel hitch, apply paint, etc. to
the contacting surfaces to prevent corrosion.
NOTICE:
Do not use axle-mounted hitches as they can cause
damage to the axle housing, wheel bearings, wheels or
tires.
Brake and safety chains

Lexus recommends trailers with brakes that conform to
any applicable federal and state / provincial
regulations.
Safety chain must always be used between the towing
vehicle and the trailer. Leave sufficient slack in the
chain for turns. The chain should cross under the trailer
tongue to prevent the tongue from dropping to the
ground in case it becomes damaged or separated. For
correct safety chain procedures, follow the hitch or
trailer manufacturer’s recommendations.
CAUTION:

If the total trailer weight exceeds 450 kg (1000 lb.),
trailer brakes are required.

Never tap into your vehicle’s hydraulic system as it will
lower its braking effectiveness.

Never tow a trailer without using a safety chain securely
attached to both the trailer and the vehicle. If damage
occurs to the coupling unit or hitch ball, there is
possible danger of the trailer wandering over into
another lane.
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 (kg / 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.

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.

DRIVING TIPS
148
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 the 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 (See Section 5).
CAUTION:
Never turn off the engine to coast down hills. Your power
steering and brake booster will not function without the
engine running. Also, the emission control system
operates properly only when the engine is running.
