5-2. Steps to take in an emergency
If the engine will not start
If the engine will not start even though correct starting procedures are
being followed (
P. 95), consider each of the following points.
■The engine will not start when the starter motor operates nor-
mally.
One of the following may be the cause of the problem.
●There may not be sufficient fuel in the vehicle’s tank.
Add fuel to the vehicle.
● The engine may be flooded.
Try to restart the engine once more following correct starting
procedures. ( P. 9 5 )
● There may be a malfunction in the engine immobilizer system.
( P. 4 7 )
■ The starter motor turn over slowly, the interior lights and head-
lights are dim, or the horn does not sound or sounds at a low vol-
ume.
One of the following may be the cause of the problem.
● The battery may be discharged. ( P. 360)
● The battery terminal connections may be loose or corroded.
■ The starter motor does not turn over, the interior lights and head-
lights do not turn on, or the horn does not sound.
One of the following may be the cause of the problem.
● One or both of the battery terminals may be disconnected.
● The battery may be discharged. ( P. 360)
Contact your Lexus dealer if the problem cannot be repaired, or if
repair procedures are unknown.

5-2. Steps to take in an emergency
If the battery is discharged
The following procedures may be used to start the engine if the battery is
discharged.
You can call your Lexus dealer, Roadside Assistance or Lexus Customer
Service.
If you have a set of jumper (or booster) cables and a second vehicle
with a 12 volt battery, you can jump start your Lexus following the steps
below.
Connecting the jumper cables.
If required, remove all vent plugs from the booster battery. Lay a
cloth over the open vents on the booster battery. (This helps reduce
the explosion hazard, personal injuries and burns.)
Positive (+) battery terminal on your vehicle.
Positive (+) battery terminal on the second vehicle.
Negative (-) battery terminal on the second vehicle.
Connect the jumper cable to ground on your vehicles as shown in
the illustration. Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately 5
minutes to recharge the battery of your vehicle.

5-2. Steps to take in an emergency
■Avoiding a discharged battery
●Turn off the headlights and the audio system while the engine is turned off.
●Turn off any unnecessary electrical compon ents when the vehicle is running at a
low speed for an extended period, such as in heavy traffic, etc.
■When the battery is removed or discharged
The following systems must be initialized.
●Moon roof (P. 4 2 )
●Variable gear ratio steering (P. 144)
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted from the battery.
●Make sure the jumper cable is connected to the correct terminal and that it is not
unintentionally in contact with any pa rt other than the intended terminal.
●Do not allow the jumper cables to come into contact with the “+” and “-” termi-
nals.
●Do not allow open flame or use matches, cigarette lighters or smoke near the
battery.
Maintain the engine sp eed of the second vehicle and start your
vehicle’s engine.
Once the vehicle’s engine ha s started, remove the jumper
cables in the exact reverse ord er in which they were con-
nected.
Once the engine starts, have the ve hicle checked at your Lexus dealer
as soon as possible.STEP3

CAUTION
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while related parts
contain lead and lead compounds. Observe the following precautions when han-
dling the battery:
●When working with the battery, always wear safety glasses and take care not to
allow any battery fluids (acid) to come into contact with skin, clothing or the vehi-
cle body.
●Do not lean over the battery.
●If the battery fluid comes into contact with the skin or eyes, immediately wash the
affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention can be
received.
●Always wash your hands after handling the battery support, terminals, and other
battery-related parts.
●Do not allow children near the battery.
NOTICE
■To prevent damaging the vehicle
Do not pull- or push-start the vehicle, because the three-way catalytic converter
may overheat and become a fire hazard.
■When handling jumper cables
Be careful that the jumper cables do not become tangled in the cooling fan or any
of the belts when connectin g or disconnecting them.
