Instantaneous fuel consumption mode
Instantaneous fuel consumption is calculated and
displayed based on distance and fuel consumption for 2
seconds with the engine running.
The displayed value is updated every 2 seconds.
Note that an accurate figure may not be shown in the following
cases.

LUGGAGE STOWAGEPRECAUTIONS
When stowing luggage or cargo in or on the vehicle,
observe the following:
Put luggage or cargo in the luggage compartment 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
To prevent luggage or packages from sliding forward
during braking, do not stack anything in the luggage
compartment higher than the seatbacks. Keep
luggage or packages low, as close to the floor as
possible.
 Never allow anyone to ride in the luggage
compartment. It is not designed for passengers.
They should ride in their seats with their seat belts
properly fastened. Otherwise, they are much more
likely to suffer serious bodily injury, in the event of
sudden braking or a collision.
Do not place anything on the luggage cover. Such
items may be thrown about and possibly injury
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.

AIR CONDITIONING
185
If quick circulation of cooled air is desired, push the air intake
control
button for RECIRCULATED AIR. The indicator light will
come on.
For normal use, it is best to keep the air intake control button
set to the OUTSIDE AIR mode. If recirculated air is used during
heating, the windows will fog up more easily.
If manual onoff of the air conditioning is desired
Push the “A/C” button to turn the air conditioning on and push
it again to turn the air conditioning off.
The air conditioning does not work if the outside temperature
is lowered down to around 0 C (32F).
If the system is used for ventilation, heating in dry weather or
removing frost or exterior fog on the windshield, turn the air
conditioning off once it is no longer required. This will improve
fuel economy. The air conditioning can be used for year −round
automatic temperature control including cooling and
dehumidifying operation.
If the air conditioning compressor does not operate, the
indicator of the “A/C” button will blink. If the indicator of the
“A/C” button blinks even when the “A/C” button is pushed
again, have the compressor checked by your nearest Lexus
dealer.
(b) Windshield defogging and defrosting
To remove interior fog on the windshield
Push the windshield air flow button.
To remove frost or exterior fog on the windshield
1. Push the “TEMP” button to set the maximum temperature.
2. Push the windshield air flow button.
3. Push the fan speed control button on the right side to obtain
a maximum air flow.
4. Leave the “A/C” button off.

THREEWAY CATALYTICCONVERTERS
Threeway catalytic converters are emission control
devices installed in the exhaust system.
The purpose is to reduce pollutants in the exhaust gas.
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
threeway 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 threeway catalytic
converter.
 Do not allow the engine to run at idle speed for more
than 20 minutes.
 Avoid racing the engine.
 Do not pushstart or pullstart 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, electric
ignition system or fuel system could cause an
extremely high threeway catalytic converter
temperature.
 If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a checkup as
soon as possible. Remember, your Lexus dealer
knows your vehicle and its threeway catalytic
converter system best.
