B: 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.
CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:
 Turn off the active height control suspension by
pushing the active height control switch.
 Follow jacking instructions.
 Do not put any part of your body under a vehicle
supported by a jack. Personal injury may occur.
 Do not start or run the engine while your vehicle
is supported by the jack.

IN CASE OF AN EMERGENCY
340
Stop the vehicle on a level firm ground, firmly
set the parking brake and put the transmission
in “P”. Block the wheel diagonally opposite to
the one being changed if necessary.
 Make sure to set the jack properly in the jack
point. Raising the vehicle with jack improperly
positioned will damage the vehicle or may allow
the vehicle to fall off the jack and cause
personal injury.
 Never get under the vehicle when the vehicle is
supported by the jack alone.
 Use the jack only for lifting your vehicle during
wheel changing.
 Do not raise the vehicle with someone in the
vehicle.
 When raising the vehicle, do not place any
objects on top of or underneath the jack.
 Raise the vehicle only high enough to remove
and change the tire.
NOTICE
Do not continue driving with a deflated tire.
Driving even a short distance can damage a tire
and wheel beyond repair.

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.
When storing the jack, put it into place and secure to
prevent it from flying forward during a collision or sudden
braking.

To remove the spare tire:
1. Remove the spare tire carrier lid using a flathead
screwdriver.
2. Insert the end of the jack handle extension into the
lowering screw and turn it counterclockwise with the
handle, making sure the handle remains firmly fitted
onto the jack handle extension.
3. After the tire is lowered completely to the ground,
remove the holding bracket.
When storing the spare tire, put it in place with the outer
side of the wheel facing up. Then secure the tire, taking
care that the tire goes straight up without catching on any
other part, to prevent it fr om 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.

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.
To raise the vehicle, insert the jack handle extension into
the jack (it is a loose fit) and turn it clockwise with the
handle, making sure the handle remains firmly fitted
onto the jack handle extension. As the jack touches the
vehicle and begins to lift, double− check that it is properly
positioned.
CAUTION
Never get under the vehicle when the vehicle 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.
Roll the spare wheel into position and align the holes in
the wheel with the bolts. Then lift up the wheel and get
at least the top bolt started through its hole. Wiggle the
tire and press it back over the other bolts.

10. Reinstall the wheel ornament.
Put the wheel ornament into position and then tap it
firmly with the side or heel of your hand to snap it into
place.
CAUTION
Take due care in handling the ornament to avoid
unexpected personal injury.
11. After changing the wheel, check the air pressure
of the replaced tire. Stow all the tools, jack and flat
tire securely. If the pressure of the replaced tire is low, drive slowly to
the nearest service station and fill to the correct
pressure.
Do not forget to reinstall the tire valve cap as dirt and
moisture could get into the valve core and possibly
cause air leakage
. If the cap is missing, put a new one
on as soon as possible.
This is the same procedure for changing or rotating your
tires.
CAUTION
Before driving, make sure all the tools, jack and
flat tire are securely in place in their storage
location to reduce the possibility of personal
injury during a collision or sudden braking.

MAINTENANCE
389
Accelerator pedal
Check
the pedal for smooth operation and uneven pedal ef fort
or catching.
Brake pedal
Check the pedal for smooth operation and the proper
clearance and free play. Check the brake booster function.
Brakes
In a safe place, check that the brakes do not pull to one side
when applied.
Parking brake
Check that the lever has the proper travel and that, on a safe
incline, your vehicle is held securely with only the parking
brake applied.
Automatic transmission “Park” mechanism
Check the lock release button of the selector lever for proper
and smooth operation. On a safe incline, check that your
vehicle is held securely with the selector lever in “P” position
and all brakes released.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary.
Fluid leaks
Check underneath for leaking fuel, oil, water or other fluid after
the vehicle has been parked for a while. If you smell fuel fumes
or notice any leak, have the cause found and corrected
immediately.
Doors and engine hood
Check that all doors and back door, operate smoothly and all
latches lock securely. Make sure the engine hood secondary
latch secures the hood when the primary latch is released.
Tire inflation pressure
Check the pressure with a gauge every two weeks, or at
least once a month and adjust as shown on the tire and
loading information label. See page 424 for additional
information.
Tire surface
Check the tires carefully for cuts, damage or excessive
wear. See page 438 for additional information.

clues are:
 Engine missing, stumbling, or pinging
 Appreciable loss of power
 Strange engine noises
 A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
 Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
 Flat−looking tires, excessive tire squeal when cornering,
uneven tire wear
 Vehicle pulls to one side when driving straight on a level
road
 Strange noises related to suspension movement
 Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
 Engine coolant temperature continually higher than normal
 Engine continually runs hot; oil pressure gauge stays low.
