B: If no steam is coming from your engine:
Leave the engine running and turn off the air conditioning.
Check the following.

Is the cooling fan operating?
 Is the coolant in the acceptable range?
 Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
 Do not attempt to remove the radiator cap when the
engine and radiator are hot. Serious injury could
result from scalding hot fluid and steam blown out
under pressure.
If the cooling fan is not operating or the coolant is not in the
acceptable range, turn off the engine and call your Lexus
dealer.
If both conditions are O.K., after the engine coolant
temperature has cooled to normal, continue driving your
vehicle.
If the engine coolant temperature does not cool down, or your
vehicle overheats again, have it checked as soon as possible
by your Lexus dealer.

IF YOUR VEHICLE BECOMESSTUCK
If your vehicle becomes stuck in snow, mud, sand, etc.
then you may attempt to rock the vehicle free by moving
it forward and backward.
Turn off the active traction control system to become
unstuck to allow the tires to spin enough to remove the
vehicle from the obstruction. (For details, see “Vehicle
stability control system” on page 290.)
CAUTION
Do not attempt to rock the vehicle free by moving it
forward and backward if people or objects are anywhere
near the vehicle. During the rocking operation the
vehicle may suddenly move forward or backward as it
becomes unstuck, causing injury or damage to nearby
people or objects.
NOTICE
If you rock your vehicle, observe the following
precautions to prevent damage to the transmission and
other parts.
 Do not depress the accelerator pedal while shifting
the selector lever or before the transmission is
completely shifted to forward or reverse gear.
 Do not race the engine and avoid spinning the
wheels.
 If your vehicle remains stuck after rocking the vehicle
several times, consider other ways such as towing.

(d) Emergency towing
40x600a
If towing is necessary, we recommend you to have it done
by your Lexus dealer or a commercial tow truck service.
If towing service is not available in an emergency, your
vehicle may be temporarily towed by a cable or chain
secured to the emergency towing hook. Use extreme
caution when towing the vehicle.
NOTICE
Never tow a vehicle from the rear with four wheels on the
ground. This may cause serious damage to the
transmission.
A 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 hook
and towing cable or chain. The hook and towing cable
or chain may break and cause serious injury or damage.
NOTICE
 Do not use front and rear eyelets. It is not designed
for towing.
 Use only a cable or chain specifically intended for
use in towing vehicles. Securely fasten the cable or
chain to the towing hook 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).

IN CASE OF AN EMERGENCY
356
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 hook 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 hook. Apply steady and even force.
 To avoid damaging the hook, do not pull from the side or at
a vertical angle. Always pull straight ahead.
CAUTION
If the emergency towing hook is used to get out when
your vehicle becomes stuck in the mud, sand or other
condition from which the vehicle cannot be driven out
under its own power, make sure to observe the
precautions mentioned below. Otherwise, excessive
stress will be put on the hook and the towing cable or
chain may break, causing serious injury or damage.
If the towing vehicle can hardly move, do not forcibly
continue the towing. Contact your Lexus dealer or a
commercial tow truck service for assistance.
 Tow the vehicle as straight ahead as possible.
 Keep away from the vehicle during towing.
Tips for towing a stuck vehicle:
The following methods are effective to use when your
vehicle is stuck in the mud, sand or other condition from
which the vehicle cannot be driven out under its own
power. Use extreme caution when towing the vehicle. In
addition, keep away from the vehic les and towing cable or
chain when towing.
 Remove the sand and soil in the front and the back of the
tires.
 Place stones or wood under the tires.

Those standards were based
on comprehensive and periodic
evaluations of the relevant scientific literature. Over 120
scientists, engineers, and physicians from universities,
government health agencies, and industry reviewed the
available body of research to develop the ANSI Standard
(C95.1).
The design of the Lexus Link System complies with the FCC
guidelines in addition to those standards.

IN CASE OF AN EMERGENCY
378Voice command error messages:
“Pardon”
The system has not been able to match your command with a
word that it knows. Repeating the command distinctly should
fix the problem. After 3 pardon responses, the system will try
to guess the command you are requesting. If correct, say
“Yes”, if not, say “No” and the system will prompt you with its
next−best guess.
“Slower, please”
Repeat the command after a short pause. This response
normally happens if you say a command before the system is
ready for it or if there is substantial background noise.
General tips for better speech recognition:
<Noise>
Noise may confuse the speech recognition system. You
usually get better performance from the system in quieter
conditions:

The air conditioning/heater fan creates noise. Turn it down
or off for better speech system performance.
 Driving at high speeds creates louder engine noise and
wind noise. You may get better results at lower speeds.
 An open window or an open moon roof results in more noise
in the vehicle. Close all windows for better results.
 Noisy rainstorms can also reduce performance.
 If passengers are talking while you use the speech system,
it may be confused by their speech. You will get better
results if all occupants of the vehicle are quiet while the
system is listening for commands.
<When to speak>
Personal calling—the system is only listening for about 5
seconds aft er it prompts you to speak. If the system does not
hear a response, it will prompt you again, or cancel the
transaction. If you begin to speak too soon, it will tell you
“Slower, please”. Try pausing for a half second before
speaking.

IN CASE OF AN EMERGENCY

IF YOU LOSE YOUR KEYS ORLOCK YOURSELF OUT
You can purchase a new key at your Lexus dealer if you
can give them the key number and master key.
Even if you lose only one key, contact your Lexus dealer to
make a new key. If you lose all your master keys, you cannot
make new keys; the whole engine immobilizer system must be
replaced.
See the suggestion given in “Keys” on page 8.
You can use the wireless remote control system with the new
key. Contact your Lexus dealer for detailed information.
If your keys are locked in the vehicle and you cannot get a
duplicate, many Lexus dealers can still open the door for you
using sp ecial tools. If your vehicle is equipped with Lexus Link
System, call the Lexus Link Call Center 1 −800−25−LEXUS
(Toll−Free) (1 −800− 255−3987) and select the option for Lexus
Link. Once you provide the Lexus Link Call Center Advisor
with your Lexus Link PIN (Personal Identification Number),
they will unlock your vehicle.
NOTICE
You must provide the Lexus Link operator with your
Lexus Link PIN (Personal Identification Number ) before
they lock/unlock your vehicle or activate a remote horn
and lights. However, the Lexus Link System will not be
able to lock or unlock your vehicle or perform lights
flashing/remote horn if it has been parked for 48 hours
or more after the ignition is turned off. Upon
subscription expiration, all Lexus Link services (i.e.
automatic notification, emergency call functions,
service call functions, remote door locking/unlocking
function, remote horn and lights function) are
deactivated.
If you must break a window to get in, we suggest breaking the
smallest side window because it is the least expensive to
replace. Be extremely cautious to avoid glass cuts.
