You can adjust the brightness of the display. See
ªInstrument panel light controlº on page 58 for details.
The automatic air conditioning automatically maintains
the set temperature.
In the automatic operation mode, the air conditioning selects
the most suitable fan speed, air flow, air intake and on±off of
the air conditioning according to the temperature.
The ignition key must be in the ªONº position.
NOTICE
To prevent the battery from being discharged, do not leave the air conditioning on longer than necessarywhen the engine is not running.

AIR CONDITIONING
196However, once selecting ªRECIRCULATED AIRº of the air
intake manually will make this function inoperable. In order to
make this function operable again, first select ªOUTSIDE AIRº
of the air intake, turn off the ignition switch, and start the engine
again. Then this function return to be operable.
If manual on±off of the air conditioning is desired ±
Push the ªA/Cº 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 0C (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 ªA/Cº button will blink. If the indicator of the
ªA/Cº button blinks even when the ªA/Cº button is pushed
again, have the compressor checked by your nearest Lexus
dealer.

THREE±WAY CATALYTICCONVERTER
SV31040
Three±way catalytic converters are emission control
devices installed in the exhaust system.
It looks somewhat like a muffler, but its 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 three±way catalytic converter may cause it to overheatand create a fire hazard. To prevent this and otherdamage, observe the following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low fuel level; runningout of fuel could cause the engine to misfire, creatingan excessive load on the three±way catalyticconverter.
Do not allow the engine to run at idle speed for morethan 20 minutes.
Avoid racing the engine.
Do not push±start or pull±start your vehicle.
Do not turn off the ignition while the vehicle ismoving.
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 stallsfrequently, take your vehicle in for a check±up assoon as possible. Remember, your Lexus dealer
knows your vehicle and its three±way catalyticconverter system best.

IGNITION SWITCH WITH STEERINGLOCK
SS31002
ªSTARTº ± Starter motor on. The key will return to the
ªONº position when released.
For starting tips, see page 237.
ªONº ± Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the key in the ªONº position if the engine
is not running. The battery will discharge and theelectronic ignition system could be damaged.
ªACCº ± Accessories such as the radio operate, but the
engine is off. If you leave the key in the ªACCº or ªLOCKº position and open
the driver's door, a buzzer will remind you to remove the key.*
NOTE: *The volume or interval of beep sound can be
changed. Ask your Lexus dealer for details.
SS31003
ªLOCKº ± Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
Manual transmission: To turn the key from ªACCº to the
ªLOCKº position, you must push in the key.
Automatic transmission: To turn the key from ªACCº to the
ªLOCKº position you must put the transmission selector lever
in the ªPº position and you must push in the key.
Once you remove the key, the engine immobilizer system is
automatically set. See ªEngine immobilizer systemº on page
12.

AUTOMATIC TRANSMISSION
Your automatic transmission has a shift lock system to
minimize the possibility of incorrect operation. This
means you can only shift out of ªPº position when the
brake pedal is depressed with the ignition switch in ªONº
position. ()
SV31020

The shift position is displayed on the instrument
cluster.
P: Parking, engine starting and key removal position
R: Reverse position
N: Neutral position
D: Normal driving position (Shifting into overdrive possible)
M: Position for manual shifting up or downshifting
When the cruise control is being used, even if you
downshift from ª5º to ª4º, engine braking will not be
enabled because the cruise control is not cancelled. For
the operation to decrease the vehicle speed, see page 251.
3, 2: Position for more powerful engine braking
L: Position for maximum engine braking

Correct use of the automatic transmission is explained in
the following parts.
(a) Normal driving

(c) Using engine braking
(d) Using the ª3º, ª2º and ªLº positions
(e) Backing up
(f) Parking
(g) Good driving practice

1. Start the engine as instructed in ªHow to start the
engineº on page 237.
The transmission must be in ªPº or ªNº. The engine will not sta\
rt
in any drive position even if the ignition key is turned to
ªSTARTº.
CAUTION
The selector lever knob can become extremely hot after
parking under the sun.

STARTING AND DRIVING

CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over 40 km/h (25 mph) with your foot off the
accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a great
speed change will occur so it is better to drive without the cruise
control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.
CAUTION
 To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snow±covered) or winding roads.
 Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
Turning the system on
SV31029
To operate the cruise control, push the main switch. This turns
the system on. The indicator light in the instrument cluster
shows that you can now set your desired cruising speed.
Another push on the switch will turn the system completely off.
When the ignition key is turned off, the main switch is also
automatically turned off. To use the cruise control again, push
the main switch again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the main switch off when not using the cruise control.
