DRIVING TIPS
413
Trailer lights
Your vehicle is equipped with a wire harness stored in the rear
end underbody. Use either of them to connect and operate the
trailer lights. However, the trailer lights must comply with
federal, state/provincial and local regulations. See your local
recreational vehicle dealer or rental agency for the correct type
of wiring and relays for your trailer. Check for correct operation
of the turn signals and stop lights each time you hitch up. Direct
splicing may damage your vehicle’s electrical system and
cause a malfunction of your lights.
Breakin schedule
Lexus recommends that you do not tow a trailer with a new
vehicle or a vehicle with any new power train component
(engine, transmission, differential, wheel bearing, etc.) for the
first 800 km (500 miles) of driving.
Maintenance
 If you tow a trailer, your vehicle will require more frequent
maintenance due to the additional load. For this
information, please refer to the scheduled maintenance
information in the “Owner’s Manual Supplement/Scheduled
Maintenance”.
 Retighten all fixing bolts of the towing ball and bracket after
approximately 1000 km (600 miles) of trailer driving.
Connecting a trailer
Stop your vehicle and a trailer in line and perform the following:
1. Put the rear height control air suspension in the “LO” (low)
mode. Turn the ignition switch off or push the “HEIGHT
CONTROL OFF” switch to turn off the rear height control air
suspension.
2. Connect a trailer.
3. Turn the ignition switch on or push the “HEIGHT CONTROL
OFF” switch to turn on the rear height control air suspension.
Select the “N” (normal) mode with the height select switch.
Disconnecting a trailer
Stop your vehicle and a trailer in line and perform the following:
1. Put the rear height control air suspension in the “LO” (low)
mode. (Make sure the vehicle height is in the “LO” (low) mode
by pushing the height select switch on the “
” side.)
2. Turn the ignition switch off or push the “HEIGHT CONTROL
OFF” switch to turn off the rear height control air suspension.
3. Set the supporting leg of a trailer on the ground and raise the
hitch by 100 mm (4 in.).
4. Turn the ignition switch on or push the “HEIGHT CONTROL
OFF” switch to turn on the rear height control air suspension.

IF YOUR ENGINE STALLS WHILEDRIVING
If your engine stalls while driving...
1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Turn the ignition key to “ACC” or “LOCK”, and try starting the
engine again.
If the engine will not start, see “If your vehicle will not start”\
.
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.
IF YOUR VEHICLE WILL NOT START
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in “How to start the
engine” on page 348 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobilizer system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, there may be a
malfunction in the immobilizer system. Call your Lexus dealer.
See “Keys” on page 8.
If the engine is not turning over or is turning over too
slowly —
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked,
the battery is discharged. You may try jump starting. See “(c)
Jump starting” for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
“Foreword”.)

IN CASE OF AN EMERGENCY
427
NOTICE
Do not pull or pushstart the vehicle. It may damage
the vehicle or cause a collision when the engine starts.
Also the threeway catalytic converter may overheat
and become a fire hazard.
If the engine turns over at its normal speed but will not
start —
1. Turn the ignition key to “ACC” or “LOCK” and try starting the
engine again.
2. The engine may be flooded because of repeated cranking.
See “(b) Starting a flooded engine” for further instructions.
3. If the engine still will not start, it needs adjustment or repair.
Call a Lexus dealer, Roadside Assistance or Customer Service
Assistance. (See “Foreword”.)
(b) Starting a flooded engine
If the engine will not start, your engine may be flooded
because of repeated cranking.
If this happens, turn the ignition key to “START” with the
accelerator pedal fully depressed, and hold the key at this
position for about 30 seconds. Then the cranking hold function
stops cranking automatically, and you can try starting the
engine with your foot off the accelerator pedal.
If the engine does not start, wait a few minutes and try again.
If the engine still will not start, it needs adjustment or repair.
Call a Lexus dealer, Roadside Assistance or Customer Service
Assistance. (See “Foreword”.)
(c) Jump starting
To avoid serious personal injury and damage to your
vehicle which might result from battery explosion, acid
burns, electrical burns, or damaged electronic
components, these instructions must be followed
precisely.
If you are unsure about how to follow this procedure, we
strongly recommend that you seek help from your Lexus
dealer, Roadside Assistance or Customer Service Assistance.
(See “Foreword”.)

IN CASE OF AN EMERGENCY
430If the first start attempt is not successful...
Check
that the clamp on the jumper cables are tight. Recharge
the discharged battery with the jumper cables connected for
several minutes and restart your engine in the normal way.
If the another attempt is not successful, the battery may be
depleted. Have it checked at your Lexus dealer.
IF YOU CANNOT INCREASE ENGINE SPEED
If engine speed does not increase when the accelerator pedal
is depressed, there may be a problem somewhere in the
electronic throttle control system.
At this time, vibration may occur. However, if you depress the
accelerator pedal more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle checked by your
Lexus dealer as soon as possible.
Even if the abnormality of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to “ACC” or “LOCK” position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.

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.

IN CASE OF AN EMERGENCY
453
CAUTION
If the emergency towing eyelet 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 eyelet 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 vehicles 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.
IF YOU CANNOT SHIFT AUTOMATIC
TRANSMISSION SELECTOR LEVER
If you cannot shift the selector lever out of “P” position to
other positions even tho ugh the brake pedal is depressed,
use the shift lock override button as follows:
1Turn the ignition key to “LOCK”. Make sure the parking
brake is applied.
2Pry up the cover with a flathead screwdriver or equivalent.

Safety information for the Lexus Link System
Important!: Read this information before using the Lexus
Link System.
EXPOSURE TO RADIO FREQUENCY SIGNALS
The Lexus Link System to be installed in your vehicle is a low
power radio transmitter and receiver. When the ignition is
turned to the “ON” position, it receives and also sends out radio
frequency (RF) signals.
In August 1996, the Federal Communications Commission
(FCC) adopted RF exposure guidelines with safety levels for
mobile wireless phones. Those guidelines are consistent with
the safety standards previously set by both U.S. and
international standards bodies.
 ANSI C95.1 (1992)*
1
NCRP Report 86 (1986)*2
ICNIRP (1996)*3
*1: American National Standards Institute
*2: National Council on Radiation Protection and
Measurements
*
3: International Commission on Non −Ionizing Radiation
Protection 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.

Lexus Link System warning light (red)
When the ignition is turned to the “ON” position, the warning
light comes on for 2 seconds, then goes off. As soon as it goes
out, the indicator light comes on. This means the Lexus Link
System is operating properly. The indicator light should remain
on to inform you that you have an active subscription. If your
Lexus Link subscription has expired, the indicator light should
go off. To activate your Lexus Link System, press the
“SERVICES” button. To learn more about your subscription
status or how to renew or extend your subscription, please
push the “SERVICES” button to speak to a Lexus Link Advisor,
or you may dial toll free 1−800−25 Lexus (Toll −Free)
(1−800−255−3987) and select the option for Lexus Link. If
problems are detected in the Lexus Link System, the warning
light comes on or you will hear “A system error has been
detected. Please contact your Lexus dealer.” In either case,
take your vehicle to your Lexus dealer. In some cases, even if your subscription has expired, the
indicator light may come on. This is due to the time delay
required to process the deactivation of your Lexus Link
System. During this period, when you push the “SERVICES”
button, your call will be forwarded to enrollment. Once the
deactivation process has been completed, the indicator light
will go off.
NOTICE
The indicator light is the
primary means to let you know
the status of your subscription. It is important to be
aware that an active subscription is required to receive
safety and security services. If the indicator light is
disabled, your subscription has expired. If you would
like to renew your subscription for Lexus Link services,
please contact Lexus Link Call Center by pushing the
“SERVICES” button twice, dial toll free 180025 Lexus
(TollFree) (18002553987) and select the option for
