2006 LEXUS LX470 air conditioning

DRIVING TIPS
326
Because of the added load of the trailer, your vehicle’s
engine may overheat on hot days (at temperatures over
30 C [85 F]) when going up a long or steep grade with a
trailer. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in
use), pull your vehicle off the road and stop in a safe spot.
See “If your vehicle overheats” on page 338.
 Always place wheel blocks under both the vehicle and trailer
wheels when parking. Apply the parking brake firmly. Put
the transmission in “P”. Avoid parking on a slope with a
trailer, but if it cannot be avoided, do so only after performing
the following:
1. Apply the brakes and keep them applied.
2. Have someone place wheel blocks under both the vehicle
and trailer wheels.
3. When the wheel blocks are in place, release your brakes
slowly until the blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into “P” and turn off the engine. When restarting out after parking on a slope:
1. With the transmission in “P” position, start the engine. Be
sure to keep the brake pedal depressed.
2. Shift into the “3”, “2”, “L” or “R” position.
3. Release the
parking brake and brake pedal and slowly pull
or back away from the wheel blocks. Stop and apply your
brakes.
4. Have someone retrieve the blocks.
CAUTION
 Do not exceed 72 km/h (45 mph) or the posted towing
speed limit, whichever is lower. Because instability
(swaying) of a towing vehicletrailer combination
usually increases as the speed increases, exceeding
72 km/h (45 mph) may cause loss of control.
 Slow down and downshift before descending steep
or long downhill grades. Do not make sudden
downshifts.
 Avoid holding the brake pedal down too long or too
frequently. This could cause the brakes to overheat
and result in reduced braking efficiency.

IN CASE OF AN EMERGENCY
339
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 YOU HAVE A FLAT TIRE
1. Reduce your speed gradually, keeping a straight line.
Move cautiously off the road to a safe place − well away
from the traffic. Avoid stopping on the center divider of
a highway. Park on a level spot with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission
in “P”.
4. Have everyone get out of the vehicle on the side away
from traffic.
5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:
 Turn off the active height control suspension by
pushing the active height control switch.
 Follow jacking instructions.
 Do not put any part of your body under a vehicle
supported by a jack. Personal injury may occur.
 Do not start or run the engine while your vehicle
is supported by the jack.

IN CASE OF AN EMERGENCY
374STORING/DELETING NUMBERS IN MEMORY
(NAMETAGS)
Your Lexus Link System can store up to 20 phone
numbers. These numbers can be dialed by simply saying
“Call”, then saying the nametag.
Tips for creating nametags:

Short nametags that are similar may be easily confused by
the system. You may get better recognition of your
nametags if you make them longer, for example “George
Washington” (no pause), instead of “George” only.
 The best way to store a nametag is when it is quiet inside
the vehicle. The vehicle should be stationary and the air
conditioning fan turned off.
 When you have finished speaking your phone number, you
do not need to say “Store number” or “Dial” to indicate that
you are done. If you pause and say nothing, the system will
ask you if you want to store or dial. Say “Yes”. To store a nametag:
1. Press the phone button.
You will hear “Lexus Link ready”.
2. Say “Store”.
You will hear “Phone number to store, please”.
3. Say the number you wish to store with no pauses.
Lexus Link will repeat the number, then you will hear “Yes or
No”.
4. Say “Yes” (or “No” to try again).
You will hear “Nametag, please” (or Number not stored).
5. Say “(new nametag)”.
You will hear “About to store (new nametag)” and “Does that
sound OK?”
6. Say “Yes” (or “No” to try again).
You will hear “Storing (new nametag)”.

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 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.

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.

MAINTENANCE
390
Tire rotation
Rotate the tires according to the maintenance schedule.
(For scheduled maintenance information, please refer to
the “Owner’s Manual Supplement / Scheduled
Maintenance”.) See page 437 for additional information.DOES YOUR VEHICLE NEED
REPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip −offs that indicate service is needed. Some important
clues are:
 Engine missing, stumbling, or pinging
 Appreciable loss of power
 Strange engine noises
 A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
 Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
 Flat−looking tires, excessive tire squeal when cornering,
uneven tire wear
 Vehicle pulls to one side when driving straight on a level
road
 Strange noises related to suspension movement
 Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
 Engine coolant temperature continually higher than normal
 Engine continually runs hot; oil pressure gauge stays low.
