AIR CONDITIONING
206SETTING OPERATION manual control
When one of the manual control buttons is depressed
while operating in automatic mode, the mode relevant to
the depressed button is set. Other conditions continue to
be adjusted automatically.
If manual air flow selection is desired
20X021a
The outlets from which air is delivered can be selected
manually by pressing the button. The function of each mode
is as follows:
1
Panel − Air flows mainly from the instrument panel vents.
2
Bilevel − Air flows from both the floor vents and the
instrument panel vents.
3 Floor − Air flows mainly from the floor vents.
It is recommended that you close the lower vent. For details
about this, see page 212.
4 Floor/Windshield − Air flows mainly from the floor vents
and windshield vents.
It is recommended that you close the lower vent. For details
about this, see page 212.
If quick heating or cooling is desired
Turn the “TEMP” knob until “MAX. HOT” or “MAX. COLD”
appears on the display.
If manual fan speed control is desired
21x600
 1 Fan speed at low 2Fan speed at high
The fan speed can be set to your desired speed by pushing the
appropriate side of fan speed control button. The higher the

If manual switching of air intake is desired
20X023a
Each time you push the air intake control button, the mode
changes in order from the RECIRCULATED AIR mode to
AUTOMATIC mode to OUTSIDE AIR mode, then back to the
RECIRCULATED
AIR mode. Each indicator light shows which
mode is now selected.
1 RECIRCULATED mode If quick circulation of cooled air
is desired, select this mode.
2 EXHAUST GAS AUTOMATIC mode If the outside air
contains harmful substances like exhaust gas (i.e., when
the vehicle running just in front of your vehicle accelerates
rapidly), the system changes automatically from the
OUTSIDE AIR mode (with indicators
2
and 3 on) to
the RECIRCULATED mode (with indicators 1
and 2
on).
3 OUTSIDE AIR mode The system will take fresh outside
air into the vehicle. Turning off the air conditioning manually will cancel the
EXHAUST
GAS AUTOMATIC mode. If you select the “AUTO”
mode during fan operating, the air conditioning turns on and
the EXHAUST GAS AUTOMATIC mode will operate.
For normal use, it is best to keep the air intake control button
set to OUTSIDE AIR mode. If recirculated air is used during
heating, the windows will fog up more easily.
In the following cases, the RECIRCULATED mode may
change to the OUTSIDE AIR mode automatically to prevent
interior fog.
 When the outside temperature becomes lower than 4 C
(39 F).
 When the air conditioning compressor malfunctions.
 When the air conditioning cooler refrigerant decreases.
To change the sensitivity of the sensor switching between
the RECIRCULA TED and OUTSIDE AIR in the AUTOMATIC
mode, push the air intake control button until the “AUTO”
indicator light flashes. The display changes as illustrated
below.
The sensitivity of the sensor can be adjusted only while the
vehicle has stopped.

20X062d
When you turn the “TEMP” knob, the sensitivity changes from
“+3” down to “−3”. If you do not operate any button for a few
seconds or if you push a button other than the air intake control
button and temperature control knob, the previous display
returns.
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. If you turn off the air
conditioning manually, the EXHAUST GAS AUTOMATIC
mode will be cancelled.
If the outside temperature is lowered down to around 0 C
(32 F), the air conditioning will turn off automatically. At this
time, the indicator on the A/C button is off and the EXHAUST
GAS AUTOMATIC indicator light remains on. However, the
EXHAUST GAS AUTOMA TIC mode does not operate. When
the air conditioning turns on as with the raised temperature, the
EXHAUST GAS AUTOMATIC mode resumes. 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.

of the windshield to fog up blocking your vision.

STARTING AND DRIVING
255

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 back door closed while driving. An open or
unsealed back door 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, open the
windows and close the back door to ensure plenty of
fresh air enters the vehicle. If you can smell exhaust
fumes even though there are no other vehicles in the
surrounding area, have your vehicle checked by your
Lexus dealer. Continued inhalation of exhaust fumes
can lead to death by gas poisoning.

STARTING AND DRIVING
264
(c) Using the “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for strong engine
braking as described previously.
With the selector lever in “3”, “2” or “L”, you can start the vehicle
in motion as with the lever in “D”.
With the selector lever in “3” or “2”, the vehicle will start in firs\
t
gear and automatically shift to second gear.
With the selector lever in “L”, the transmission is engaged in
first gear.
NOTICE
 Be careful not to overrev the engine. Watch the
tachometer to keep engine rpm from going into the
red zone. The approximate maximum allowable
speed for each position is given below for your
reference:
Transmission Transfer
“L” “H”
“4” 72 km/h (45 mph) 178 km/h (111 mph)
“3” 52 km/h (32 mph) 127 km/h (79 mph)
“2” 36 km/h (22 mph) 87 km/h (54 mph)
“L” 20 km/h (12 mph) 51 km/h (32 mph)
 Do not continue hill climbing or hard towing for a long
time in the “3”, “2” or “L” position. This may cause
severe automatic transmission damage from
overheating. To prevent such damage, “4” position
should be used in hill climbing or hard towing.
(d) Backing up
31X010e
 1
Brake pedal 2“R” (Reverse) position
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the
selector lever to the “R” position.
NOTICE
Never shift into reverse while the vehicle is moving.
When you are backing up, you can adjust the outside rear view
mirror on the passenger’s side down quickly. For details, see
page 195.

STARTING AND DRIVING
293
VARIABLE GEAR RATIO STEERINGSYSTEM
The variable gear ratio steering system adjusts the wheel
turning angle depending on the vehicle speed and how
much you turn the steering wheel.
The vehicle wheel turning angle will be changed with a smaller
degree of wheel maneuvering when you are driving at very low
speed such as when putting your vehicle into a garage.
In the following cases, to prevent the system from overheating,
the system could be temporarily deactivated with the change
in the center position of the steering wheel. This is not a
malfunction. After the cause of the problem is eliminated, the
system will return to normal automatically after a few minutes.
 If you continue maneuvering the steering wheel when the
vehicle is stopped or running at very low speed
 If you continue driving holding the steering wheel to the
extreme right or left
 If you maneuver the steering wheel immediately after
starting the engine at less than about −30C (− 22F) While the system is not functioning, a larger degree of wheel
maneuvering is needed during driving at low speed. If the
center position of the steering wheel is changed frequently,
have your vehicle inspected at your Lexus dealer.
CAUTION
Take due care especially when driving at low speed as
the vehicle changes direction in greater proportion to
the steering wheel maneuvering.
NOTICE
Do not disconnect the battery with the steering wheel
turned, or the center position of the steering wheel
could be slightly and temporarily changed. However,
after driving for a short while, the system will return to
normal
and the center position of the steering wheel will
be in the appropriate position.
The light will flash if you disconnect and reconnect the battery
terminal. This is because the system is reset temporarily.
However, it is no problem to drive. To turn off the light, drive for
a short while. The system will be set automatically and return
to normal.

DRIVING TIPS
312
TIPS FOR DRIVING IN VARIOUSCONDITIONS
Always slow down in gusty crosswinds. This will allow you
much better control.
 Drive slowly onto curbs and, if possible, at a right angle.
Avoid driving onto high, sharp −edged objects and other
road hazards. Failure to do so can lead to severe tire
damage such as a tire burst.
Drive slowly when passing over bumps or travelling on a
bumpy road. Otherwise, the impact could cause severe
damage to the tires and/or wheels.
 When parking on a hill, turn the front wheels until they touch
the curb so that the vehicle will not roll. Apply the parking
brake, and place the transmission in “P”. If necessary, block
the wheels.
 Washing your vehicle or driving through deep water may get
the brakes wet. To see whether they are wet, check that
there is no traffic near you and then press the pedal lightly.
If you do not feel a normal braking force, the brakes are
probably wet. To dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake
applied. If they still do not work saf ely, pull to the side of the
road and call a Lexus dealer for assistance.
CAUTION
 Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.
 Do not leave your vehicle unattended while the
engine is running.
 Do not rest your foot on the brake pedal while driving.
It can cause dangerous overheating, needless wear,
and poor fuel economy.
 To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 263.
 Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to skid or spin.
 Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140 km/h
(85 mph) unless your vehicle has highspeed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are highspeed
capability tires or not before driving at such speeds.
