2004 Lexus GX470 service

GAUGES, METERS AND SERVICE REMINDER INDICATORS
71 Driving range mode
The distance the vehicle can travel with the remaining fuel
is calculated and displayed based on the quantity of
remaining fuel and past fuel consumption.
The driving range display indicates the approximate distance
that you can drive until the fuel gauge reaches Eº. It is different
from the actual distance traveled.
The displayed value is updated every time the fuel required to
travel 0.6 miles (1 km) is consumed.
Every time you refuel the vehicle, the calculation is reset.
The actual driving range varies with driving habits and road
conditions. If fuel consumption is good, the driving range will
be longer. If fuel consumption is poor, the driving range will be
shorter.
If the low fuel level warning light comes on, refuel even if the
display indicates that the vehicle can be driven further.Average vehicle speed modeAverage vehicle speed is calculated and displayed based
on total driving distance and total driving time with the
engine running.
The displayed value is updated every 10 seconds.
To reset the calculations, push and hold the RESETº button for
more than 1 second.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
72Barometer mode
In barometer mode, the atmospheric pressure in the
vehicle is displayed.
The displayed atmospheric pressure ranges from 17.8 IN.HG
(600 hPa) up to 31.0 IN.HG (1050 hPa).
The displayed value is updated every 2 seconds.
The displayed value may deviate from the actual atmospheric
pressure depending on opening or closing of the windows and
doors and the driving conditions.Altimeter modeIn altimeter mode, the approximate altitude is displayed.
The displayed altitude ranges from -1500 ft. (-500 m) up to
13000 ft. (4000 m).
As the altitude value is converted from the atmospheric
pressure, it can be easily affected by air motion and
temperature, so the indication may vary. The indicated altitude
of a single position may deviate according to the atmospheric
pressure and temperature.
The displayed value is updated every 2 seconds.
RECTIFICATION OF THE ALTITUDE
Rectification is valid only when the correct altitude is known.
While the altitude mode is on the display, push the 
º or º
button to increase or decrease the altitude by 50 ft. (10 m).
To reset the rectified altitude, push and hold the RESETº
button for more than 1 second.

the driving time exceeds 19:59, the counter returns to 0:00.

BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, head restraint height
and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
Remember to check that the service reminder indicators
function when turning the key to ONº, and check the fuel
gauge to see that you have sufficient fuel.
IGNITION SWITCH WITH STEERING
LOCK
STARTº Ð Starter motor on. The key will return to the
ONº position when released.
For starting tips, see page 363.
It is not a malfunction even if the needle of the tachometer, fuel
gauge or engine coolant temperature gauge returns to the
bottom position when the ignition switch is turned to the
STARTº position.
ONº Ð Engine on and all accessories on.
This is the normal driving position.
It is not malfunction even if the needle on the speedometer may
move when the ignition switch is turned to the ONº position.

STARTING AND DRIVING
401 ABSº warning light
The light comes on when the ignition key is turned to the ONº
position. If the anti-lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the ABSº warning light is on (and the brake system
warning light is off), the anti-lock brake system, the brake
assist system, the active traction control system and the
vehicle stability control system do/does not operate, but the
brake system still operates conventionally.
When the ABSº warning light is on (and the brake system
warning light is off), the anti-lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.If either of the following conditions occurs, this indicates
a malfunction somewhere in the components monitored
by the warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle.
The light does not come on when the ignition key is turned
to the ONº position, or remains on.
The light comes on while you are driving.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the ABSº warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the anti-lock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Either of the following conditions may occur, but do not
indicate a malfunction:
The light may stay on for about 60 seconds after the ignition
key is turned to the ONº position. It is normal if it turns off
after a while.
Depressing the brake pedal repeatedly may turn on the
light. It is normal if it turns off after a few seconds.
