2006 Lexus GX470 ECU

IN CASE OF AN EMERGENCY
452A driver must be in the vehicle to steer it and operate the
brakes.
Towing in this manner may be done only on hard
−surfaced
roads for a short distance and at low speeds. Also, the wheels,
axles, drive train, steering and brakes must all be in good
condition.
CAUTION
Use extreme caution when towing the vehicle. Avoid
sudden starts or erratic driving maneuvers which would
place excessive stress on the emergency towing eyelet
and towing cable or chain. The eyelet and towing cable
or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use
in towing vehicles. Securely fasten the cable or chain
to the towing eyelet provided.
Before towing, check that the center differential is unlocked.
(The indicator light must be off with the ignition on.) Release
the parking brake and put the transmission in “N”. The ignition
key must be in “ACC” (engine off) or “ON” (engine running).
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work so steering and
braking will be much harder than usual.
Emergency towing hook precautions:
 Before emergency towing, check that the eyelet is not
broken or damaged and that the installation bolts are not
loose.
 Fasten the towing cable or chain securely to the hook.
 Do not jerk the eyelet. Apply steady and even force.
 To avoid damaging the eyelet, do not pull from the side or at
a vertical angle. Always pull straight ahead.

Personal calling: oneword commands

Commands — The personal calling system listens for only
one word at a time. (There are some exceptions: two− word
phrases that are spoken and understood as a single word,
e.g., “Advanced services” and “My number”)
 Numbers — When inputting a phone number, the personal
calling system listens for a continuous string of digits. It can
recognize 7 −, 10−, and 11−digit numbers as well as the
number 911. When inputting security codes or
voice−activated keypad numbers, you must say them one
digit at a time.
 Say “Help” at the “Lexus Link ready” prompt to hear the list
of personal calling commands. Tips for entering a phone number using the dial and store
commands:

Say the entire 7 −, 10− , or 11 −digit number and wait for the
system to respond. You do not need to say “Dial”, “Store”,
or “Verify” after the phone number.
 If you want to enter a number that is not 7−, 10− or 11 −digit,
use the digit dial or digit store commands.
 Do not pause between the digits. If there is a long pause
between digits, the system may think that you have finished
saying the entire number.
 The system does not recognize the words “Hundred” or
“Thousand”. Instead, you must say each digit. For
example, a number starting with “1 −800 ...” is pronounced
“one−eight−zero−zero...”.
 The system often works better when the digits are combined
smoothly into a single phrase. Try saying the entire phone
number more rapidly.
 If problems continue when saying the entire phone number,
try using the digit dial or digit store commands to enter one
digit at a time.
