THREEWAY CATALYTICCONVERTERS
31L353a
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,
electronic 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
297

To ensure that the threeway 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
“Owner’s Manual Supplement / Scheduled
Maintenance”.
ENGINE EXHAUST CAUTION
CAUTION
Avoid inhaling the engine exhaust. It contains
carbon monoxide, which is a colorless and odorless
gas. It can cause unconsciousness or even death.
 Make sure the exhaust system has no holes or loose
connections. The system should be checked from
time to time. If you hit something, or notice a change
in the sound of the exhaust, have the system checked
immediately.
 Do not run the engine in a garage or enclosed area
except for the time needed to drive the vehicle in or
out. The exhaust gases cannot escape, making this
a particularly dangerous situation.
 Do not remain for a long time in a parked vehicle with
the engine running. If it is unavoidable, however, do
so only in an unconfined area and adjust the heating
or cooling system to force outside air into the vehicle.
Keep the trunk lid closed while driving. An open or
unsealed trunk lid may cause exhaust gases to be
drawn into the vehicle.
 To allow proper operation of your vehicle’s
ventilation system, keep the inlet grilles in front of the
windshield clear of snow, leaves, or other
obstructions.
 If you smell exhaust fumes in the vehicle, drive with
the windows open and the trunk lid closed. Have the
cause immediately located and corrected.

STARTING AND DRIVING
298
BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat cushion length, seat position, seatback angle,
seat cushion angle, seat cushion height, 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 ignition switch to “ON”, and check the
fuel gauge to see that you have sufficient fuel.
SMART IGNITION SWITCH WITH STEERING LOCK
31L345a
Carrying a smart key allows you to start the engine
without the key being inserted into the ignition switch.
The smart key system can be deactivated using a key cancel
switch. For details, see “Deactivating the smart key system”
on page 34.

STARTING AND DRIVING
299
31L346a
When you enter the vehicle carrying a sm art key and push
the ignition switch, the electronic code in the key is
automatically checked as to whether it corresponds to the
registered ID code for the vehicle. The key indicator light
comes on, the steering column lock is released, and the
engine immobilizer system is cancelled.
At this time, the security indicator light goes off and you can
start the engine when you turn the ignition switch and the key
indicator light does not come on. When you turn the ignition
switch, turn it slowly and surely. If you turn it quickly, it may
become stuck. To free it, see the following “If the ignition switch
seems to be stuck”.
If you push the ignition switch when the smart key is not within
the effective range of the smart key system, a warning tone
sounds and “Key is not Detected” appears on the display. If the ignition switch seems to be stuck:
To free the ignition switch, perform the following:
31L638
1. Push the ignition switch.
31L639
2. Be sure to push the ignition switch while turning the
steering wheel slightly in either direction, and then turn
the switch.

STARTING AND DRIVING
300“START” Starter motor on. The ignition switch will
return to the “ON” position when released.
For starting tips, see page 304.
“ON” Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the ignition switch 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.
31L347
“LOCK” Engine is off and the steering wheel is locked.
When
you leave your vehicle, be sure to turn the ignition switch
to the “LOCK” position and carry the smart key.
 If you open the driver’s door without returning the ignition
switch to the “LOCK” position, beeps keep sounding while
the door is opened.
 If you close a door to leave your vehicle while carrying a key
on which the ignition switch has not been returned to the
“LOCK” position, “Key is not Detected” appears on the
multi−information display, a warning tone sounds inside and
beeps sound outside.
 If the selector lever is in a position other than “P”, you cannot
turn the ignition switch to the “LOCK” position. At this time,
when you open the driver’s door and are going to get out of
the vehicle, “Shift to P Range” appears on the
multi−information display and a warning tone sounds inside.

STARTING AND DRIVING
301
When you turn the ignition switch to the “LOCK” position, the
engine immobilizer system is automatically set. See “Engine
immobilizer system” on page 17.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the ignition switch only to “ACC”.
