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.

DRIVING TIPS
268

Because of the added load of the trailer, your vehicle's
engine may overheat on hot days (at temperatures over
30C [85 F]) when going up a long or steep grade with a
trailer. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if
in use), pull your vehicle off the road and stop in a safe
spot. See ºIf your vehicle overheatsº on page 280 of this
manual.

Always place wheel blocks under both the vehicle and
trailer wheels when parking. Apply the parking brake
firmly. Put the transmission in ºPº. 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 keep them applied.
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 ºPº and turn off the engine.
When restarting out after parking on a slope:
1. With the transmission in ºPº position, start the engine. Be
sure to keep the brake pedal depressed. 2. Shift into the º3º, º2º, ºLº or ºRº 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.
