(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 ”START” 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 ”Foreword”.)
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. (See ”Foreword”.).
CAUTION
Batteries contain sulfuric acid which is poisonous and
corrosive. Wear protective safety glasses when jump
starting, and avoid spilling acid on your skin, clothing, or
vehicle.
If you should accidentally get acid on yourself or in your
eyes, remove any contaminated clothing and flush the
affected area with water immediately. Then get immediate
medical attention. If possible, continue to apply water with
a sponge or cloth while en route to the medical office.
The gas normally produced by a battery will explode if a
flame or spark is brought near. Use only standardized
jumper cables and do not smoke or light a match while
jump starting.
NOTICE
The battery used for boosting must be 12 V. Do not jump start
unless you are sure that the booster battery is correct.

Place the ignition key in the ”ACC” position.
NOTICE
Do not tow with the key removed or in the ”LOCK” 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

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
”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.
IF YOU CANNOT SHIFT
AUTOMATIC TRANSMISSION
SELECTOR LEVER
40L025-3
If you cannot shift the selector lever, use the shift lock override
button as follows:
1
Turn the ignition key to ”LOCK” or ”ACC”. Make sure the
parking brake is applied. Pry up the cover with a flatbladed
screwdriver or equivalent.

2
Insert your finger, the screwdriver or equivalent into the hole
to push down the shift lock override button. You can shift the
selector lever while pushing the button.
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 OR
LOCK 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 ”Keys” on page 8.
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.
