light lexus LS400 1994 Engine / 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.

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

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
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.
