CAUTION
To reduce the risk of sliding under the lap belt during a
collision, avoid reclining the seatback any more than needed.
The seat belts provide maximum protection in a frontal or rear
collision when the driver and the passenger are sitting up
straight and well back in the seats. If you are reclined, the lap
belt may slide past your hips and apply restraint forces
directly to the abdomen. Therefore, in the event of a frontal
collision, the risk of personal injury may increase with
increasing recline of the seatback.

sold in Canada are provided with a bracket set in the glovebox.
DRIVING POSITION MEMORY
SYSTEM
The micro computer can memorize the position of the driver’s seat,
the height of the shoulder belt anchor of the driver’s seat belt, and the
positions of the tilt and telescopic steering, and outside rear view
mirrors. Two different driving position profiles can be entered into
the computer’s memory.
Recording a driving position in the computer’s memory can only be
done when the ignition key is in the ”ON” position and the shift lever
is in the ”P” position.
Setting a driving position
16L055
1. Adjust the driver’s seat, driver’s shoulder belt anchor, tilt and
telescopic steering and outside rear view mirrors to the desired
position.
2. While pushing the ”SET” button, push button ”1” or ”2” until
the signal beeps.

STARTING AND DRIVING
171
Cruise control failure warning
If the ”CRUISE” indicator light in the instrument cluster flashes
when using the cruise control, push the main switch to turn the
system off and then push it again to turn it on.
If any of the following conditions then occurs, there is some trouble
in the cruise control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it comes on.
If this is the case, contact your Lexus dealer and have your Lexus
inspected.
ELECTRONICALLY MODULATED
AIR SUSPENSION
(U.S.A. ONLY)
This electronically modulated air suspension adjusts the
damping effect on the shock absorbers and the vehicle height.
This adjustment is automatically made in response to the driving
conditions to provide good riding comfort and stability in all
driving conditions.
(a) Vehicle height adjustment
31L015-3
This system maintains a stable vehicle height, regardless of
occupants and luggage weight. You can select one of the
following modes using a selector switch.

STARTING AND DRIVING
172”NORMAL” mode For driving on roads with a normal surface.
”HIGH” mode For driving on rough roads which are unsurfaced
or continually bumpy.
The damping effect is set slightly firmer in ”HIGH” mode. So you
may feel the vibration of the vehicle compared to in ”NORMAL”
mode. However, this does not mean a malfunction in the system. We
recommend you use a ”NORMAL” mode in normal driving.
To change the mode, push the selector switch.
”NORMAL” mode
The vehicle height remains at normal height at all driving speeds.
”HIGH” mode
The vehicle height switches between the following two vehicle
heights according to the driving conditions:
Vehicle height
Driving condition
NormalMedium and high speed driving
HighLow speed driving
31L016-2
The indicator light shows ”HIGH” mode is selected.
When you turn the ignition key to the ”ON” position, the indicator
light will come on for 2 seconds in any mode.
NOTICE
For vehicles equipped with the height control switch, be sure to
turn the ignition switch off before jacking. If this is not done, the
vehicle height adjustment function will operate, which may
cause body damage.
(b) Malfunction warning
If the ”HI” indicator light blinks, there is a malfunction in this
system. Have the system checked by your Lexus dealer at the first
opportunity.

IN CASE OF AN EMERGENCY
197 B: If no steam is coming from your engine:
Leave the engine running and turn off the air conditioning. Check
the following.
Is the cooling fan operating?
Is the coolant in the acceptable range?
Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing away
from the moving fan and engine drive belt.
Do not attempt to remove the radiator cap when the engine
and radiator are hot. Serious injury could result from
scalding hot fluid and steam blown out under pressure.
If the cooling fan is not operating or the coolant is not in the
acceptable range, turn off the engine and call your Lexus dealer.
If both conditions are O.K., after the engine coolant temperature has
cooled to normal, continue driving your vehicle.
If the engine coolant temperature does not cool down, or your
vehicle overheats again, have it checked as soon as possible by your
Lexus dealer.
IF YOU HAVE A FLAT TIRE
1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place well away from the traffic.
Avoid stopping on the center divider of a highway. Park on a level
spot with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in ”P”.
4. Have everyone get out of the vehicle on the side away from
traffic.
5. Read the following instructions thoroughly.
NOTICE
For vehicles equipped with the height control switch, be sure to
turn the ignition switch off before jacking. If this is not done, the
vehicle height adjustment function will operate, which may
cause body damage.
CAUTION
When jacking, be sure to observe the following to reduce the
possibility of personal injury:
Follow jacking instructions.
Do not start or run the engine while your vehicle is
supported by the jack.
