2004 Lexus GX470 automatic transmission

STARTING AND DRIVING
402The indicator light tells when the differential lock is engaged.
Note that the differential is not still locked as long as the
indicator light remains off.
When
the operation is not completed, the indicator blinks. If the
indicator light does not go off when you push out the center
differential lock switch, drive straight ahead while accelerating
or decelerating, or drive in reverse.
The center differential lock system operation is not completed
within 5 seconds while the cruise control system is set, cancel
the cruise control system. To cancel the cruise control system,
see Cruise controlº on page 408. If the indicator light does not go off when you push out the
center differential lock button, drive straight ahead while
accelerating or decelerating, or drive in reverse.
See (b) Shifting procedureº for further instructions.
Advice for driving on slippery roads in Lº (low speed
position) mode
If you shift the four-wheel drive control lever to Lº, the
automatic transmission lever to 2º when you drive in steep
off-road areas, the output of the brake can be controlled
effectively by the active traction control system, which assists
the driver to control the driving power of 4 wheels.
Use the Lº position of the automatic transmission lever for
maximum power and traction when your wheels get stuck or
when you drive down a steep incline. In the following cases,
the out put of the brake can be controlled by the active traction
control
system if the engine speed is under 3000 rpm (normally
engine speed is under 3000 rpm when the wheels get unstuck).
 The four-wheel drive control lever in the Lº position and the
automatic transmission lever in the Lº position or the
automatic transmission lever in the Dº or 2º with the
transmission downshifting to the first gear.
 The four-wheel drive control lever in the Lº position and the
automatic transmission lever in the Rº position
(As for the automatic transmission lever positions, see
Automatic transmissionº on page 392.)

CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over about 40 km/h (25 mph) with your foot
off the accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a greater
speed change will occur so it is better to drive without the cruise
control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the driving pattern selector switch.
CAUTION
 To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snow-covered) or winding roads.
 Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
Turning the system on
To operate the cruise control, push the ON-OFFº button. This
turns the system on. The indicator light in the instrument
cluster shows that you can now set your desired cruising
speed. Another push on the button will turn the system
completely off.
When the ignition key is turned off, the ON-OFFº button is also
automatically turned off. To use the cruise control again, push
the ON-OFFº button again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the ON-OFFº button off when not using the cruise
control.

Setting operation

Each function is described below.
1Setting at a desired speed.
The transmission must be in Dº before you set the cruise
control speed.
Bring the vehicle to the desired speed, press the control lever
downward in the - SETº direction and release it. This sets the
vehicle at that speed. Now you may take your foot off the
accelerator pedal. If you need acceleration Ð for example,
when passing Ð depress the accelerator pedal enough for the
vehicle to exceed the set speed. When you release the
accelerator pedal, the vehicle will return to the speed set prior
to the acceleration.
2Cancelling the preset speed
You can cancel the preset speed by either of the following:
a. Pulling the control lever in the CANCELº direction.
b. Depressing the brake pedal.
If the vehicle speed falls below about 40 km/h (25 mph), the
preset speed will be automatically cancelled.
If the vehicle speed drops 16 km/h (10 mph) below the preset
speed, the preset speed will also automatically be cancelled.
If the preset speed automatically cancels out for other than
these reasons, have your vehicle checked by your Lexus
dealer at the earliest opportunity.
3Resetting to a faster speed
Press the control lever upward in the + RESº direction and
hold it. Release the lever when the desired speed is attained.
While the lever is held upward, the vehicle will gradually gain
speed.
When the difference between the actual vehicle speed and the
set speed is less than 5 km/h (3 mph), the set speed can be
increased 1.6 km/h (1 mph) each time by pressing the control
lever upward in the + RESº direction quickly within 0.6
seconds.
However, a quicker way to reset is to accelerate the vehicle and
then press the control lever downward in the - SETº direction.

HOW TO SAVE FUEL AND MAKEYOUR VEHICLE LAST LONGER
Improving fuel economy is easy Ð just take it easy. It will help
make your vehicle last longer, too. Here are some specific tips
on how to save money on both fuel and repairs:
 Keep your tires inflated at the correct pressure. Check
the pressure every two weeks, or at least once a month.
Underinflation causes tire wear and wastes fuel.
 Do not carry unneeded weight in your vehicle. Excess
weight puts a heavier load on the engine, causing greater
fuel consumption.
 Avoid lengthy warm-up idling. Once the engine is
running smoothly, begin driving Ð but gently. Remember,
however, that on cold winter days this may take a little
longer.
 Always keep the automatic transmission selector lever
in the Dº position when engine braking is not required.
Driving with the overdrive off will reduce the fuel economy.
(For details, see Automatic transmissionº on page 392.)
 Accelerate slowly and smoothly. Avoid jackrabbit starts.
 Avoid long engine idling. If you have a long wait and you
are not in traffic, it is better to turn off the engine and start
again later. 
Avoid engine over-revving. Use a gear position suitable
for the road on which you are traveling.
 Avoid continuous speeding up and slowing down.
Stop-and-go driving wastes fuel.
 Avoid unnecessary stopping and braking. Maintain a
steady pace. Try to time the traf fic signals so you only need
to stop as little as possible or take advantage of through
streets to avoid traffic lights. Keep a proper distance from
other vehicles to avoid sudden braking. This will also
reduce wear on your brakes.
 Avoid heavy traffic or traffic jams whenever possible.
 Do not rest your foot on the brake pedal. This causes
premature wear, overheating and poor fuel economy.
 Maintain a m oderate speed on highways. The faster you
drive, the greater the fuel consumption. By reducing your
speed, you will cut down on fuel consumption.
 Keep the front wheels in proper alignment. Avoid hitting
the curb and slow down on rough roads. Improper
alignment not only causes faster tire wear but also puts an
extra load on the engine, which, in turn, wastes fuel.
 Keep the bottom of your vehicle free from mud, etc. This
not only lessens weight but also helps prevent corrosion.
