DRIVING TIPS

Tires
Ensure that your vehicle's tires are properly inflated. Adjust
the tire inflation pressure to the recommended cold tire
inflation pressure indicated below.
Tire inflation pressure: 220 kPa (2.2 kgf/cm
2 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
Your vehicle is equipped with a wire harness stored in the rear
end underbody. Use either of them to connect and operate the
trailer lights. However, the 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 ªOwner's Manual Supplement/Scheduled
Maintenanceº.
 Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.

4. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the
vehicle.
Turn the wheel nuts counterclockwise to loosen them.
To get maximum leverage, fit the wrench to the nut
so that the handle is on the right side, as shown
above. Grab the wrench near the end of the handle
and pull up on the handle. Be careful that the wrench
does not slip off the nut.
Do not remove the nuts yet Ð just unscrew them
about one±half turn.
CAUTION
Never use oil or grease on the bolts or nuts.
The nuts may loose and the wheels may fall off,
which could cause a serious accident.

6. After making sure no one is in the vehicle, raise
it high enough so that the spare tire can be
installed.
Allow for the fact that you need more ground
clearance when putting on the spare tire than when
removing the flat tire.
To raise the vehicle, insert the jack handle extension
into the jack (it is a loose fit) and turn it clockwise
with the handle, making sure the handle remains firmly
fitted onto the jack handle extension. As the jack
touches the vehicle and begins to lift, double±check
that it is properly positioned.
CAUTION
Never get under the vehicle when the vehicle
is supported by the jack alone.
7. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.
Roll the spare wheel into position and align the holes
in the wheel with the bolts. Then lift up the wheel
and get at least the top bolt started through its hole.
Wiggle the tire and press it back over the other bolts.

IN CASE OF AN EMERGENCY
512
Before putting on the wheel, remove any corrosion
on the mounting surfaces with a wire brush or such.
Installation of wheels without good metal±to±metal
contact at the mounting surface can cause wheel nuts
to loosen and eventually cause a wheel to come off
while driving.8. Reinstall all the wheel nuts finger tight.
Reinstall the wheel nuts and tighten them as much
as you can by hand. Press the tire back and see
if you can tighten them more.
CAUTION
Never use oil or grease on the bolts or nuts.
Doing so may lead to overtightening the nuts
and damaging the bolts. The nuts may loose and
the wheels may fall off, which could cause a
serious accident. If there is oil or grease on any
bolt or nut, clean it.

IN CASE OF AN EMERGENCY
523
A driver must be in the vehicle to steer it and operate the
brakes.
Towing in this manner may be done only on hard±surfaced
roads
for a short distance and at low speeds. Also, the wheels,
axles, drive train, steering and brakes must all be in good
condition.
CAUTION
Use extreme caution when towing the vehicle. Avoid
sudden starts or erratic driving maneuvers which would
place excessive stress on the emergency towing eyelet
and towing cable or chain. The eyelet and towing cable
or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use in towing vehicles. Securely fasten the cable or chainto the towing eyelet provided.
Before towing, check that the center differential is unlocked.
(The indicator light must be off with the ignition on.) Release
the parking brake and put the transmission in ªNº. The ignition
key must be in ªACCº (engine off) or ªONº (engine running).CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work so steering and
braking will be much harder than usual.
Emergency towing hook precautions:
 Before emergency towing, check that the eyelet is not
broken or damaged and that the installation bolts are not
loose.
 Fasten the towing cable or chain securely to the hook.
 Do not jerk the eyelet. Apply steady and even force.
 To avoid damaging the eyelet, do not pull from the side or at
a vertical angle. Always pull straight ahead.
