If other vehicles are driving outside of the laser radar
detection range, a delay in the detection of the
vehicle cutting in at short range or failure to detect a
motorcycle running on the side of the same lane will
occur. In this case, the dynamic laser cruise control
system will not function properly.
 When a slower vehicle in front of you leaves the lane,
the dynamic laser cruise control will no longer detect
a vehicle ahead and will attempt to accelerate the
vehicle to the faster preset speed.
(b) Turning the system on and off
To turn the dynamic laser cruise control on, press the
“ON−OFF” button. The “CRUISE” and “READY” indicator
lights on the instrument cluster will come on to indicate that the
vehicle −to−vehicle distance control mode is operational.
Pressing the “ON −OFF” button again turns the system off.
When the system is turned off, cruising speed and
vehicle −to−vehicle distance must be reset when the
vehicle −to−vehicle distance control mode is turned on again.
When the ignition is turned off, the system is also automatically
turned off. To use dynamic laser cruise control again, press the
“ON−OFF” button again to turn it on.
When the ignition is turned off, all the preset data is cleared.
When you use the dynamic laser cruise control again, you
need to reset the data.

warning
1Warning code2 “CRUISE” indicator light
3Master warning light
If a system malfunction is detected when the
vehicle −to−vehicle distance control mode is on, the master
warning light comes on, a warning tone sounds and a warning
code appears on the display. Dynamic laser cruise control is
automatically cancelled.
If “E3” appears on the display, the “CRUISE” indicator light in
the instrument cluster also flashes. If “E1” appears on the display,
the system cannot easily
measure the vehicle −to−vehicle distance because of a dirty
laser radar sensor glass.
If this code appears, clean the sensor glass with a soft cloth
and try setting the preset speed again. If the dirt is removed
without cleaning, the system will automatically enter the ready
mode.
If the system does not enter the ready mode even after
cleaning or the code remains on the display, the system might
be malfunctioning. Although the vehicle may still be operated,
please contact your Lexus dealer.
CAUTION
Always keep the sensor glass clear and never allow it to
be covered with icicle or any substance, so it can detect
the vehicle in front.

STARTING AND DRIVING
434(a) Turning the system on and off
To turn the conventional cruise control mode on, press the
“ON−OFF” button. The “CRUISE” and “READY” indicator
lights on the
instrument panel will come on. Push the lever in
the “MODE” direction for longer than 1 second to change to
conventional cruise control mode. The indicator on the
instrument panel is as shown. You can now set the cruising
speed. Pressing the “ON− OFF” button again turns the system
off.
When the system is turned off, cruising speed must be reset
when the conventional cruise control mode is turned on again.
However, once the vehicle −to−vehicle distance control mode
activates and is used, the system cannot be changed to the
conventional cruise control mode using the above operation.
To change the mode, you must turn this system off and then on
again. Next pu sh the lever in the “MODE” direction for longer
than about 1 second. To change to the vehicle
−to−vehicle distance control mode
from the conventional cruise control mode, push the lever in
the “MODE” direction for longer than about 1 second.

4. With the vehicle stopped, push the reset switch on the left
lower instrument panel and hold it until the low tire pressure
warning light blinks three times.
Initialization is
completed after driving at the speeds of 30 km/h
(19 mph) or over for about a few hours total, when the tire
pressure warning system detects the normal tire pressure. If
the following driving conditions are satisfied, initialization will
be completed in about one hour.
 Vehicle speed varies between 30 km/h (19 mph) and 80
km/h (50 mph)
 Normal road surface
When the warning light blinks twice every second while driving,
you may be unable to reset the system. In this case, set the
system again according to the above procedure.
Do not push the reset switch without adjusting the tire inflation
pressure to the specified level. Otherwise, the low tire
pressure warning light may not come on even if the tire
pressure is low, or it may come on when the tire inflation
pressure is actually normal.
If you push the reset switch while the vehicle is moving,
initialization is not performed.
If the low tire pressure warning light does not blink when you
push and hold the reset switch, have the low pressure warning
system checked at your Lexus dealer.
BRAKE PAD WEAR LIMIT INDICATORS
The brake pad wear limit indicators on your disc brakes
give a warning noise when the brake pads are worn to the
extent that replacement is required.
If you hear a squealing or scraping noise while driving, have the
brake pads checked and replaced by your Lexus dealer as
soon as possible. Expensive rotor damage can result if the
pads are not replaced when needed.

CARGO AND LUGGAGE
Stowage precautions
When stowing cargo and luggage in or on the
vehicle, observe the following:
Put cargo and luggage in the luggage compartment
when at all possible. Be sure all items are secured
in place.
 Be careful to keep the vehicle level. Placing the
weight as far forward as possible helps maintain
vehicle balance.
 For better fuel economy, do not carry unnecessary
weight.
CAUTION
To prevent cargo and luggage from sliding
forward during braking, do not stack anything
in the luggage compartment higher than the
seatbacks. Keep cargo and luggage low, as
close to the floor as possible.
Never allow anyone to ride in the luggage
compartment. It is not designed for
passengers. They should ride in their seats
with their seat belts properly fastened.
Otherwise, they are much more likely to suffer
serious bodily injury, in the event of sudden
braking or a collision.
 Do not place anything on the luggage cover.
Such items may be thrown about and possibly
injure people in the vehicle during sudden
braking or an accident.
 Do not drive with objects left on top of the
instrument panel. They may interfere with the
driver’s field of view. Or they may move
during sharp vehicle acceleration or turning,
and impair the driver’s control of the vehicle.
In an accident they may injure the vehicle
occupants.

identifier for your vehicle. This number is shown on the
left top of the instrument panel and can be seen through
the windshield from outside.
On some models — This number is also stamped under
the front passenger’s seat.
This is the primary identification number for your Lexus. It is
used in registering the ownership of your vehicle.
The vehicle identification number (VIN) is also on the
Certification Label.

Quality gasoline
Automotive manufacturers in the U.S., Europe and Japan
have developed a specification for quality fuel named
WorldWide Fuel Charter (WWFC) that is expected to be
applied world wide. The WWFC consists of four
categories that depend on requi red emission levels. In the
U.S., category 4 has been adopted. The WWFC improves
air quality by providing for better emissions in vehicle
fleets, and customer satisfaction through better vehicle
performance.
Cleaner burning gasoline
Cleaner burning gasoline, including reformulated
gasoline that contains oxygenates such as ethanol or
MTBE is available in many areas.
Lexus recommends the use of cleaner burning gasoline and
appropriately blended reformulated gasoline. These types of
gasoline provide excellent vehicle performance, reduce
vehicle emissions, and improve air quality.
Oxygenates in gasoline
Lexus allows the use of oxygenate blended gasoline
where the oxygenate content is up to 10% ethanol or 15%
MTBE. If you use gasohol in your Lexus, be sure that it has
an octane rating no lower than 91.
Lexus does not recommend the use of gasoline containing
methanol.
Gasoline containing MMT
Some gasoline contain an octane enhancing additive
called MMT (Methylcyclopentadienyl Manganese
Tricarbonyl).
Lexus does not recommend the use of gasoline that contains
MMT. If fuel containing MMT is used, your emission control
system may be adversely affected. The Malfunction Indicator
Lamp on the instrument cluster may come on. If this happens,
contact your Lexus dealer for service.
