DRIVING TIPS

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.

DRIVING TIPS
261
your Lexus dealer ± they will be pleased to help.
Check
the electronic 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.
Use 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 ºPº 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.

DRIVING TIPS
262
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.
CAUTION

DRIVING TIPS
263

The total trailer weight (trailer weight plus its cargo load)
must not exceed 726 kg (1600 lb.). Exceeding this weight is
dangerous.

Trailer hitch assemblies have different weight capacities
established by the hitch manufacturer. Even though the
vehicle may be physically capable of towing a higher
weight, the operator must determine the maximum weight
rating of the particular hitch assembly and never exceed
the maximum weight rating specified for the trailer hitch.
Exceeding the maximum weight rating set by the trailer
hitch manufacturer can cause an accident resulting in
serious personal injuries.

The gross vehicle weight must not exceed the Gross V ehicle
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.

DRIVING TIPS
265
Hitches

If you wish to install a trailer hitch, your Lexus dealer
should be consulted.

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

Follow the directions supplied by the hitch manufacturer.
Lubricate the hitch ball with a light coat of grease.

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.

Remove the trailer hitch whenever you are not towing a
trailer so that the rear license plate can be seen clearly.
NOTICE

Install the trailer hitch using only the position
recommended by your Lexus dealer. Do not install the
trailer hitch on the bumper; this may cause body
damage.

Do not use axle±mounted hitches as they can cause
damage to the axle housing, wheel bearings, wheels or
tires.
Brakes and safety chains

Lexus recommends trailers with brakes that conform
to any applicable federal and state/provincial
regulations.

A 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 procedur es, 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.

DRIVING TIPS
266
Tires

Ensure that your vehicle's tires are properly inflated.
Adjust the tire pressure to the recommended cold tire
pressure indicated below:
SC400, SC 300 ± Front 220 kPa (2.2 kgf/cm
2 or bar, 32 psi)
Rear 220 kPa (2.2 kgf/cm2 or bar, 32
psi)

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 ºOwner'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.
