LUGGAGE STOWAGEPRECAUTIONS
When stowing luggage or cargo in the vehicle, observe the
following:

Put luggage or cargo in the trunk when at all possible. Be
sure all items are secured in place.

Be careful to keep the vehicle level. Placing the weight as
far forward as possible helps maintain vehicle balance.

For better fuel economy, do not carry unnecessary weight.
CAUTION

Do not place anything on the filler panel behind the rear
seatback. Such items may be thrown about and possibly
injure people in the vehicle during sudden braking or an
accident.

Do not drive with objects left on top of the instrument
panel. They may interfere with the driver's field of view.
Or they may move during sharp vehicle acceleration or
turning, and impair the driver's control of the vehicle. In
an accident they may injure the vehicle occupants.
NOTICE
Do not load the vehicle beyond the vehicle capacity
weight specified on the tire pressure label.

COMFORT ADJUSTMENT
117

Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.

Keep the belts clean and dry. If they need cleaning,
use a mild soap solution or lukewarm water. Never
use bleach, dye, or abrasive cleaners ± they may
severely weaken the belts. (See ºCleaning the
interiorº on page 409 for instructions.)

Replace the belt assembly (including bolts) if it has
been used in a severe impact. The entire assembly
should be replaced even if damage is not obvious.
Front seat belts
Make sure the seat belt hanger is secured in raised
position. If it is not, be sure to raise the seat belt hanger
until it locks in position.
You will hear a click when the seat belt hanger locks in
position.

THREE±WAY CATALYTIC CONVERTER

STARTING AND DRIVING
210
CAUTION
Keep people and combustible materials away from the
exhaust pipe while the engine is running. The exhaust gas
is very hot.
 Do not drive, idle or park your vehicle over anything that
might burn easily such as grass, leaves, paper or rags.
NOTICE
A large amount of unburned gases flowing into the
three±way catalytic converter may cause it to overheat
and create a fire hazard. To prevent this and other
damage, observe the following precautions:
Use only unleaded gasoline.
 Do not drive with an extremely low fuel level; running
out of fuel could cause the engine to misfire, creating
an excessive load on the three±way catalytic converter.
 Do not allow the engine to run at idle speed for more
than 20 minutes.
 Avoid racing the engine.
 Do not push±start or pull±start your vehicle.
Do not turn off the ignition while the vehicle is moving.
 Keep your engine in good running order.
Malfunctions in the engine electrical system,
electronic ignition system or fuel system could cause
an extremely high three±way catalytic converter
temperature.
 If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a check±up as soon
as possible. Remember, your Lexus dealer knows your
vehicle and its three±way catalytic converter system
best.
 To ensure that the three±way catalytic converter and
the entire emission control system operate properly,
your vehicle must receive the periodic inspections
required by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to the
separate ºOwner's Manual Supplement/
Maintenance Scheduleº.

STARTING AND DRIVING

Traction control failure warning
If the ºTRAC OFFº indicator/warning light flashes, contact
your Lexus dealer as soon as possible. There may be trouble
in the traction control system.
CAUTION
Under certain slippery road conditions, full traction of the
vehicle and power to the rear wheels cannot be maintained,
even though the traction control system is in operation. Do not
drive the vehicle under any speed or maneuvering conditions
which will cause the vehicle to lose traction. In situations
where the road surface is covered with ice or snow, your
vehicle should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious pace.
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic
system with two separate sub±systems. If either sub±system
should fail, the other will still work. However, the pedal will
be harder to press, and your stopping distance will be longer.
Also, the brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a single brake system.
Have your brakes fixed immediately.

STARTING AND DRIVING
251
The brake pedal pulsation caused by the anti±lock brake
system may indicate hazardous road surface conditions.
Although the anti±lock brake system assists in providing
vehicle control, it is still important to drive with all due care,
because
the anti±lock brake system cannot overcome the laws
of physics that act on your vehicle:
 Braking capability is dependent on tire friction with the
road surface. 
Even though the anti±lock brake system is operating, a
driver cannot maintain full control on certain slippery road
surfaces, when cornering at high speeds, or in violent
maneuvers.
 Avoid high speeds on wet roads. The anti±lock brake
system cannot eliminate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the vehicle in front of
you. Compared with vehicles not fitted with an anti±lock
brake system, your vehicle may require a longer stopping
distance in the following cases:
 Driving on rough, gravel or snow±covered roads.
 Driving with tire chains installed.
 Driving on roads where the road surface is pitted or has
other differences in surface height.
