flat tire Lexus GX470 2006 Basic Functions In Frequent Use / LEXUS 2006 GX470 (OM60B99U) Owner's Guide

IN CASE OF AN EMERGENCY
438
NOTICE
Tighten the spare tire clamp bolt to hold the
spare wheel carrier by the hook securely.
 Vehicles with kinetic dynamic suspension
system — Make sure that the spare tire does
not interfere with the suspension components
when the spare tire is stowed. If interference
occurs, the suspension system will be
damaged.
2. Block the wheel diagonally opposite the flat tire
to keep the vehicle from rolling when it is jacked
up.
When blocking the wheel, place a wheel block in front
of one of the front wheels or behind one of the rear
wheels.

When connecting a jack handle extension with a jack
handle end, use a Phillips−head screwdriver or jack
handle to tighten the bolts on the joints as shown in
the illustration. When connecting the jack handle with
extension, tighten the bolt on the jack handle securely.
Make sure the hollow meets the bolt on any joint when
you tighten the bolts.
NOTICE
Tighten all the joints securely. Otherwise, the
extension may come off and it may damage the
paint or vehicle body.
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.

IN CASE OF AN EMERGENCY
443
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.
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.

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 possible
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.
IF YOUR VEHICLE BECOMESSTUCK
If your vehicle becomes stuck in snow, mud, sand, etc.,
then you may attempt to rock the vehicle free by moving
it forward and backward.
In this situation, lock the center differential and turn off the
vehicle stability control system. (For details, see
“Fourwheel drive system” on page 356.)
CAUTION
Do not attempt to rock the vehicle free by moving it
forward and backward if people or objects are anywhere
near the vehicle. During the rocking operation the
vehicle may suddenly move forward or backward as it
becomes unstuck, causing injury or damage to nearby
people or objects.

IN CASE OF AN EMERGENCY

CAUTION
If the emergency towing eyelet is used to get out when
your vehicle becomes stuck in the mud, sand or other
condition from which the vehicle cannot be driven out
under its own power, make sure to observe the
precautions mentioned below. Otherwise, excessive
stress will be put on the eyelet and the towing cable or
chain may break, causing serious injury or damage.
If the towing vehicle can hardly move, do not forcibly
continue the towing. Contact your Lexus dealer or a
commercial tow truck service for assistance.
 Tow the vehicle as straight ahead as possible.
 Keep away from the vehicle during towing.
Tips for towing a stuck vehicle:
The following methods are effective to use when your
vehicle is stuck in the mud, sand or other condition from
which the vehicle cannot be driven out under its own
power. Use extreme caution when towing the vehicle. In
addition, keep away from the vehicles and towing cable or
chain when towing.
 Remove the sand and soil in the front and the back of the
tires.
 Place stones or wood under the tires.
IF YOU CANNOT SHIFT AUTOMATIC
TRANSMISSION SELECTOR LEVER
If you cannot shift the selector lever out of “P” position to
other positions even tho ugh the brake pedal is depressed,
use the shift lock override button as follows:
1Turn the ignition key to “LOCK”. Make sure the parking
brake is applied.
2Pry up the cover with a flathead screwdriver or equivalent.

MAINTENANCE

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.
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 side 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 pressure label. See page 523 for additional
information.
Tire surface
Check the tires carefully for cuts, damage or
excessive wear. See page 538 for additional
information.
Wheel nuts
When checking the tires, make sure to check the nuts
for looseness. Tighten them if necessary.
Tire rotation
Rotate the tires according to the maintenance
schedule. (For scheduled maintenance information,
please refer to the “Owner’s Manual
Supplement/Scheduled Maintenance”.) See page 537
for additional information.

DOES YOUR VEHICLE NEEDREPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip −offs that indicate service is needed. Some important
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 If you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.
