20L037

Use only compact discs labeled as shown. CD±R
(CD±Recordable), CD±RW (CD±Re±writable) and
personal computer use CD±ROMs may not be
playable on your compact disc player.
 Your compact disc player is intended for use with 12
cm (4.7 in.) discs only.
 Extremely high temperature can keep your compact
disc player from working. On hot days, use air
conditioning to cool the vehicle interior before you
listen to a disc.
 Bumpy roads or other vibrations may make your
compact disc player skip.
 If moisture gets into your compact disc player, you
may not hear any sound even though your compact
disc player appears to be working. Remove the
magazine from the player and wait until it dries.

DRIVING TIPS
335
wheels will be closer than the vehicle wheels to the
inside of the turn. Therefore, compensate for this by
making a larger than normal turning radius with your
vehicle.

Crosswinds and rough roads will adversely affect
handling of your vehicle and trailer, causing sway.
Pay attention to the rear from time to time to prepare
yourself for being passed by large trucks or buses,
which may cause your vehicle and trailer to sway. If
swaying happens, firmly grip the steering wheel and
reduce speed immediately but gradually. Never
increase speed. If it is necessary to reduce speed,
brake slowly. Steer straight ahead. If you make no
extreme correction with the steering or brakes, your
vehicle and trailer will stabilize.
 Be careful when passing other vehicles. Passing
requires considerable distance. After passing a
vehicle, do not forget the l ength of your trailer and be
sure you have plenty of room before changing lanes.
 In order to maintain efficient engine braking and
electrical charging performance, do not use
overdrive.
 Because of the added load of the trailer, your vehicle's
engine may overheat on hot days (at temperatures
over 30C [85F]) 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 ªIf your vehicle
overheatsº on page 348.
 Always place wheel blocks under both the vehicle
and trailer wheels when parking. Apply the parking
brake firmly. Put the transmission in ªPº. Avoid

IN CASE OF AN EMERGENCY
349
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your
emergency flashers. Put the transmission in ªPº and
apply the parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there
is no sign of steam or coolant. Your engine could have
been seriously damaged already. Call your Lexus
dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until
there is no steam. Escaping steam or coolant is sign of
very high pressure.
B: If no steam is coming from your engine:
Leave the engine running and turn off the air
conditioning. Check the following.
 Is the cooling fan operating?
 Is the coolant in the acceptable range?
 Is the engine drive belt O.K.?

MAINTENANCE
385
DOES YOUR VEHICLE NEEDREPAIRING?
Be on the alert for changes in performance and sounds,
and visual tip±offs that indicate service is needed. Some
important clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (However, water
dripping from the air conditioning after use is normal.)

Change in exhaust sound (This may indicate a
dangerous carbon monoxide leak. Drive with the
windows open and have the exhaust system checked
immediately.)

Flat±looking tires, excessive tire squeal when
cornering, uneven tire wear

Vehicle pulls to one side when driving straight on a
level road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake
pedal, pedal almost touches floors, vehicle pulls to
one side when braking

Engine coolant temperature continually higher than
normal If you notice any of these clues, take your vehicle to your
Lexus dealer as soon as possible. It probably needs
adjustment or repair.
