If the downhill assist control system indicator light flashes, the
transmission selector lever may be in ªNº or four±wheel drive
control lever may be in the ªHº position.
If the indicator light does not come on when the switch is
pushed, contact your Lexus dealer.

Slip indicator light
With the vehicle traveling at a speed of 25 km/h (15 mph) or
less, release your foot from the accelerator or brake pedal to
activate the system. The vehicle will descend the hill at a low
speed. While the system is operating, the slip indicator light on
the instrument panel will flash and the stop lights and high
mounted stoplight will be lit.
If you push the ªDACº switch to turn the system off while it is
in operation, the system will stop operating gradually. The
downhill assist control system indicator light will flash to alert
the driver. To continue driving at a low speed, push the ªDACº
switch to turn the system on.
The slip indicator light and downhill assist control system
indicator l
ight come on for a few seconds when the ignition key
is turned to ªONº. If any of the indicator lights does not come
on when the ignition is turned on, contact your Lexus dealer.
The brake actuator temperature increases during continuous
operation of the following systems.
 Active traction control system
 Vehicle stability control system
 Downhill assist control system
 Hill±start assist control
If the brake actuator temperature becomes too high while any
of the systems is operating, a buzzer will start to sound
intermittently to indicate that the downhill assist control system
can no longer operate. In this case, stop your vehicle
immediately at a safe place.
If the system continues to operate, the buzzer sound changes
from intermittent to continuous. (The continuous buzzer
sounds for about 3 seconds.) At this time, the slip indicator light
will come on and the downhill assist control system stops
operating temporarily in order to protect the brake actuator.
(Although the downhill assist control system does not operate,
it is no problem to continue your driving.) The system will be
automatically restored after a short time and the slip indicator
light goes out.

STARTING AND DRIVING
440Keep in mind the following when driving.

The hill±start assist control operates for 5 seconds
maximally. If both the brake and accelerator pedals remain
undepressed for longer than 5 seconds, the buzzer will
sound at more frequent intervals and the system will
gradually stop operating.
 The hill±start assist control is not designed as a function for
stopping the vehicle on a uphill slope. When stopping the
vehicle, be sure to depress the brake pedal.

Selector switch

1Main position22nd position
The selector switch is located in the lower part of the
driver's side instrument panel.
The ID code is given in the sensor. To activate the air
pressure warning system, it is necessary to register the ID
code of the sensor on the selector switch in the vehicle.2 sets of ID codes can be registered. The code of the tires
originally installed on the vehicle is registered on the switch at
ªMAINº. Have a new tires set with new air pressure sensors
registered at ª2ndº by Lexus dealer.
ID codes should be registered by Lexus dealer. Once
registered,
change the setting position each time you purchase
tires and wheels. Re±registration is not required.
When purchasing new tires, consult your Lexus dealer.
CAUTION
When the tires whose ID code is registered at ªMAINº
are used, the system does not work properly with the
selector switch set at ª2ndº. If the tires whose ID code
is registered at ª2ndº are stored nearby, the system will
detect their tire pressure (and vice versa).

ENGINE
554The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way the
vehicle is driven.
More oil is consumed by high±speed driving and frequent
acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings
and cylinder walls have not become conditioned.
Oil consumption:
Max. 1.0 L per 1000 km (1.1 qt./600 miles,
0.9 Imp. qt./600 miles)
When judging the amount of oil consumption, keep in
mind that the oil may have become diluted, making it
difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips and
consumes a normal amount of oil, the dipstick may not show
any drop in the oil level at all, even after 1000 km (600 miles)
or more. This is because the oil is gradually becoming diluted
with fuel or moisture, making it appear that the oil level has not
changed.
The diluting ingredients evaporate out when the vehicle is then
driven at high speeds, as on an expressway, making it appear
that oil is excessively consumed after driving at high speeds.
Importance of engine oil level check
One of the most important points in proper vehicle
maintenance is to keep the engine oil at the optimum level so
that oil function will not be impaired. Therefore, it is essential
that the oil level be checked regularly. Lexus recommends that
the oil level be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to serious engine trouble due to insufficient oil.

engine oil levelº described below.USED ENGINE OIL
