INSIDE REAR VIEW MIRROR
16X016e
Adjust the mirror so that you can just see the rear of your
vehicle in the mirror.
Pushing the switch changes the mode between “AUTO”
and “DAY”.
The indicator comes on when the “AUTO” mode is selected.
“DAY” mode: The mirror surface is normal.
“AUTO” mode: If the mirror detects light from the
headlights of the vehicle behind you, the mirror surface
darkens slightly to reduce the reflected light.
When the inside rear view mirror surface changes, the outside
rear view mirror surfaces will also become darker.
When the ignition key is inserted and turned on, the inside rear
view mirror always turns on in the “AUTO” mode. When
the inside air temperature is low, it may take a little longer
for the mirror to darken in response to the detection of
headlights.
CAUTION
Do not adjust the mirror while the vehicle is moving.
Doing so may cause the driver to mishandle the vehicle
and an accident may occur resulting in death or serious
injuries.
16x658b
To ensure correct functioning of antiglare mirror sensors
located on both sides of the mirror, do not touch or cover
the sensors with your finger or a piece of cloth, etc.

vehicle, etc.).
 The vehicle is magnetized. (There is a magnet or a metal
object on or near the inside rear view mirror.)
 The battery has been disconnected.
 Any door is open.
If the deviation is small, the compass works to calibrate the

THREEWAY CATALYTICCONVERTERS
31X001f
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.

STARTING AND DRIVING
256
BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, head restraint height
and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
Remember to check that the service reminder indicators
function when turning the key to “ON”, and check the fuel
gauge to see that you have sufficient fuel.
IGNITION SWITCH
31X002a
“START” Starter motor on. The key will return to the
“ON” position when released.
For starting tips, see page 258.
“ON” Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the key in the “ON” position if the engine
is not running. The battery will discharge and the
electronic ignition system could be damaged.
“ACC” Accessories such as the radio operate, but the
engine is off.

STARTING AND DRIVING
257
If you leave the key in the “ACC” or “LOCK” position and open
the driver’s door, a buzzer will remind you to remove the key.
31X003a
“LOCK” Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the key from “ACC” to the “LOCK” position, you must
put the transmission selector lever in the “P” position.
Once you remove the key, the engine immobilizer system is
automatically set. See “Engine immobilizer system” on page
11 .
When starting the engine, the key may seem stuck at the
“LOCK” position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to “ACC”.
It is not a malfunction if the needles on all meters and gauges
move slightly when the key is turned to the “ACC”, “ON” or
“START” position.
Several hours after the engine is turned off, you may hear a
sound coming from underneath the luggage compartment for
several minutes. This is normal operation and does not
indicate a malfunction. (See page vii.)
