IF YOUR ENGINE STALLS WHILE
DRIVING
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. 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 130 and that you have sufficient fuel.
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”.)
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 “(b) Starting a flooded engine” 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 “Foreword”.)

IN CASE OF AN EMERGENCY
161
(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 15 seconds and
then stop cranking. Then try starting the engine with your foot
off the accelerator pedal.
If the engine does not start after 15 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 15 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 for at least 15
minutes. 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.

Booster battery
JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make
sure the vehicles are not touching. Turn off all unnecessary
lights and accessories.2. If required, remove all the 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.)
If the booster battery is an extended maintenance interval
battery, it is not necessary to remove the vent plugs.
3. If the engine in the vehicle with the booster battery is not
running, start it and let it run for a few minutes. During jump
starting, run the engine at about 2000 rpm with the accelerator
pedal lightly depressed.
4. Locate positive (+) and negative (−) terminals of each
battery. Connect the jumper cables in the exact order (
1
2 3
4
) shown in the illustration.
1
Connect a positive (red) jumper cable clamp to the
positive (+) terminal of the discharged battery.
2
Connect the clamp at the other end of the positive (red)
cable to the positive (+) terminal of the booster battery.
3
Connect a negative (black) cable clamp to the negative
(−) terminal of the booster battery.
4
Connect the clamp at the other end of the negative (black)
cable to a solid, stationary, metallic point (e.g. engine
hanging hook) away from the battery. Do not connect it to
or near any part that moves when the engine is cranked.

IN CASE OF AN EMERGENCY
163
NOTICE
When making the connections, do not lean over the
battery or accidentally let the jumper cables or clamps
touch anything except the correct battery terminals or
the ground.
5. Start your engine in the normal way. After starting, run it at
about 2000 rpm for several minutes with the accelerator pedal
lightly depressed.
6. Carefully disconnect the cables in the exact reverse order:
the negative cable and then the positive cable.
7. Carefully dispose of the battery cover cloths which may now
contain sulfuric acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is not apparent (for
example, lights left on), you should have it checked.
IF YOUR VEHICLE OVERHEATS
If your engine coolant temperature gauge indicates
overheating, if you experience a loss of power, or if you
hear a loud knocking or pinging noise, the engine has
probably overheated.
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your
emergency flashers. Put the transmission in “P” and apply the
parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there is no sign
of steam or coolant. Your engine could have been seriously
damaged already. Call your Lexus dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until
there is no steam. Escaping steam or coolant is sign of
very high pressure.

IN CASE OF AN EMERGENCY
164B: 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.
NOTICE
For vehicles equipped with the height control switch, be
sure to turn the ignition switch off before jacking. If this
is not done, the vehicle height adjustment function will
operate, which may cause body damage.
NOTICE
When jacking, be sure to observe the following to
reduce the possibility of personal injury:

Follow jacking instructions.

Use a jack only for lifting your vehicle during wheel
changing.

IN CASE OF AN EMERGENCY
165

Never get beneath the vehicle when supported by a
jack.

Do not start or run the engine while your vehicle is
supported by a jack.
 1
Tool box 2
Jack 3
Spare tire 4
Jack handle
1. Get the tool, jack and spare tire.
To prepare yourself for an emergency, you should familiarize
yourself with the use of the jack and each tool, and their
storage locations.
 1
Joint
2
When removing the jack, turn the joint by hand in the
“contract” direction until the jack is free.
3
When storing, turn the joint by hand in the “expand”
direction until the jack is firmly secured to prevent it from
flying forward during a collision or sudden braking.

IN CASE OF AN EMERGENCY
166
To remove the spare tire:
1
Remove the spare tire cover.
2
Loosen the bolt and remove it.
When storing the spare tire, place it with the inner side of the
wheel facing up. Then bolt the tire in place and install the spare
tire cover to prevent the tire from flying forward during a
collision or sudden braking.
2. Block the wheel diagonally opposite the flat tire to keep
the vehicle from rolling when it is jacked up.
When blocking a wheel, place a wheel block in front of the front
wheels or behind the rear wheels.
Paper for protecting surface
3. Remove the wheel ornament.

IN CASE OF AN EMERGENCY
167 Pry off the wheel ornament, using the screwdriver as shown.
To avoid personal injury, do not attempt to pull off the ornament
by hand.
4. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the nuts counterclockwise to loosen them. To get
maximum leverage, fit the wrench to the nut so that the handle
is on the right side, as shown above. Grab the wrench near the
end of the handle and pull up on the handle. Be careful that the
wrench does not slip off the nut.
Do not remove the nuts yet − just unscrew them about one−half
turn.
5. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid surface.
6. After making sure no one is in the vehicle, raise it high
enough so that the spare tire can be installed.
Allow for the fact that you need more ground clearance when
putting on the spare tire than when removing the flat tire.

IN CASE OF AN EMERGENCY
168To raise the vehicle, insert the jack handle into the jack (it is a
loose fit) and turn it clockwise. As the jack touches the vehicle
and begins to lift, double−check that it is properly positioned.
CAUTION
Never get under the vehicle when it is supported by the
jack alone.
7. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.
Before putting on the wheel, remove any corrosion on the
mounting surfaces with a wire brush or such. Installation of
wheels without good metal−to−metal contact at the mounting
surface can cause wheel nuts to loosen and eventually cause
a wheel to come off while driving.
8. Reinstall all the wheel nuts finger tight.
