CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of child restraint systems for
children small enough to use them.
The laws of all fifty states in the U.S.A. now require the use
of a child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint system, the child
should sit in the rear seat and must be restrained using the
vehicle's seat belt. See ºSeat beltsº on page 115 for details.

AIR CONDITIONING AND AUDIO
187
To prevent the battery from being discharged, do not leave
the car audio on longer than necessary when the engine
is not running.
To ensure the correct audio system operation:


Be careful not to spill beverages over the audio system.

Do no put anything other than a cassette tape or CD
magazine into the cassette tape slot or CD changer.

The use of cellular phone inside or near the vehicle
may cause a noise from the speakers of the audio
system which you are listening to. However, this does
not indicate a malfunction.
You can listen to the car audio when the ignition key is at
ºONº or ºACCº. However, if the engine is not running,
the key must be in the ºACCº position.
You can adjust the brightness of the display. See ºInstrument
panel light control on page 64 for details.
Audio operation is described in detail on the following pages:

Radio operation ± See page 187.

Cassette tape player operation ± See page 192.

Compact disc player operation ± See page 196.
Radio operation
(a) Listening to the radio
1. Push the
(AM) or (FM1/2) button to turn the
radio on and select either an AM or FM broadcast.

STARTING AND DRIVING
213
ºSTARTº ± Starter motor on. The key will return to the
ºONº position when released.
For starting tips, see page 216.
ºONº ± Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the key in the ºONº position if the engine is
not running. The battery will discharge and the
electronic ignition system could be damaged.
ºACCº ± Accessories such as the radio operate, but the
engine is off.
If you leave the key in the ºACCº or ºLOCKº position and
open the driver's door, a buzzer will remind you to remove the
key.

DRIVING TIPS
260

Do not rest your foot on the brake pedal while
driving. It can cause dangerous overheating,
needless wear, and poor fuel economy.

To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 234.

Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to spin or skid.

Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140
km/h (85 mph) unless your vehicle has high±speed
capability tires. Driving over 140 km/h (85 mph)
may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are high±speed
capability tires or not before driving at such speeds.

Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a
longer stopping distance, and it may pull to one side
when the brakes are applied. Also, the parking
brake will not hold the vehicle securely.WINTER DRIVING TIPS
Make sure you have a proper freeze protection of engine
coolant.
Your coolant must contain ethylene±glycol type coolant for
a proper corrosion protection of aluminum components. Use
ºToyota Long Life Coolantº or equivalent. See ºChecking
the engine coolant levelº on page 347 for instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60%
solution for your Lexus, to provide protection down to about
±50 C (±58F). Do not use more than 70% solution for better
coolant performance.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it
must be in top shape to provide enough power for winter
starting. Page 380 tells you how to visually inspect the
battery. Your Lexus dealer and most service stations will be
pleased to check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold
weather.
See page 346 for recommended viscosity. Leaving a heavy
summer oil in your vehicle during winter months may cause
harder starting. If you are not sure about which oil to use, call

IN CASE OF AN EMERGENCY
275
IF YOUR VEHICLE WILL NOTSTART
(a) Simple checks
Before making these checks, make sure you have followed
the correct starting procedure instructions in ºHow to start the
engineº on page 216 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobiliser system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, the system is
possibly broken. Call your Lexus dealer. See ºKeysº on page
12. If the engine is not turning over or is turning over too
slowly ±
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior
light.
3. If the light is out, dim or goes out when the starter is
cranked,
the battery is discharged. You may try jump starting.
See º(c) Jump startingº for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
ºForewordº.)
NOTICE
Do not pull±or push±start the vehicle. It may damage the
vehicle or cause a collision when the engine starts. Also
the three±way catalytic converter may overheat and
become a fire hazard.
If the engine turns over at its normal speed but will not
start ±
1. The engine may be flooded because of repeated cranking.
See º(b) Starting a flooded engineº for further instructions.
2. If the engine still will not start, it needs adjustment or
repair. Call a Lexus dealer, Roadside Assistance or Customer
Service Assistance. (See ºForewordº.)
