IF YOUR VEHICLE WILL NOTSTART
(a) Simple checks
Before making these checks, make sure you have followed
the correct starting procedure instructions in ºHow to start the
engineº on page 216 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobiliser 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, the system is
possibly broken. Call your Lexus dealer. See ºKeysº on page
12. 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 º(c) Jump startingº 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
ºForewordº.)
NOTICE
Do not pull±or push±start the vehicle. It may damage the
vehicle or cause a collision when the engine starts. Also
the three±way catalytic converter may overheat and
become a fire hazard.
If the engine turns over at its normal speed but will not
start ±
1. The engine may be flooded because of repeated cranking.
See º(b) Starting a flooded engineº for further instructions.
2. If the engine still will not start, it needs adjustment or
repair. Call a Lexus dealer, Roadside Assistance or Customer
Service Assistance. (See ºForewordº.)

(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 key to ºSTARTº with the accelerator
pedal held down. Continue this operation for 30 seconds and
then stop cranking. Then try starting the engine with your foot
off the accelerator pedal.
If the engine does not start after 30 seconds of cranking,
release the key, 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 ºForewordº.)
NOTICE
Do not crank for more than 30 seconds at a time. This
may overheat the starter and wiring systems.
(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.

IN CASE OF AN EMERGENCY
299
Place the ignition key in the ºACCº position.
NOTICE

Do not tow with the key removed or in the ºLOCKº
position, as the steering lock mechanism is not strong
enough to hold the front wheels straight.

When lifting wheels, take care to ensure adequate
ground clearance for towing at the opposite end of the
raised vehicle. Otherwise, the bumper and/or
underbody of the towed vehicle will be damaged
during towing.
(b) Using a flat bed truck

IN CASE OF AN EMERGENCY
305
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, release the parking brake and put the
transmission in ºNº. The ignition key must be in ºACCº
(engine off) or ºONº (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.

IF YOU CANNOT SHIFT
AUTOMATIC TRANSMISSION SELECTOR LEVER
If you cannot shift the selector lever out of ºPº position to
other positions even though the brake pedal is depressed,
use the shift lock override button as follows:
1. Turn the ignition key to ºLOCKº. Make sure the parking
brake is applied.
2. Pry up the cover with a flat±bladed screwdriver or
equivalent.

IN CASE OF AN EMERGENCY
307
3. Insert your finger, the screwdriver or equivalent into the
hole to push down the shift lock override button. You can shift
out of ºPº position only while pushing the button.
4. Shift into ºNº position.
5. Insert the cover.
6. Start the engine. For your safety, keep the brake pedal
depressed.
Be sure to have the system checked by your Lexus dealer as
soon as possible.IF YOU LOSE YOUR KEYS ORLOCK YOURSELF OUT
Many Lexus dealers can make a new key if you can give
them the key number. Since your vehicle is equipped with
the engine immobiliser system, the dealer will also need
your master key.
See the suggestion given in ºKeysº on page 12.
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 their special tools. 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 cuts from the glass.
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 system must be replaced.
