2006 Lexus GX470 tires

IN CASE OF AN EMERGENCY
453
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
487
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.

MAINTENANCE
488
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.

through “Aluminum wheel precautions” on pages 523 through 544.

CHASSIS

The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
on page 520 and 564. They are also described
on the tire and loading information label as
shown.
You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget
the spare!
The following instructions for checking tire
inflation pressure should be observed:
The pressure should be checked only when the
tires are cold. If your vehicle has been parked
for at least 3 hours and has not been driven for
more than 1.5 km or 1 mile since, you will get an
accurate cold tire inflation pressure reading.
 If you cannot adjust the tire pressure when the
tires are cold, add 20 kPa (0.2 kgf/cm
2 or bar, 2.9
psi) to 30 kPa (0.3 kgf/cm2 or bar, 4.3 psi) more
to the front tires and rear tires than the cold tire
pressure, but never exceed the maximum cold tire
pressure molded on the tire sidewall. 
Always use a tire pressure gauge. The
appearance of a tire can be misleading. Besides,
tire inflation pressures that are even just a few
pounds off can degrade handling and ride.
 Do not bleed or reduce tire inflation pressure
after driving. It is normal for the tire inflation
pressure to be higher after driving.
 Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located
so that the vehicle is balanced.

CHASSIS
526
Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.
If a tire frequently needs refilling, have it checked by
your Lexus dealer.
CAUTION
Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.
Low tire pressure (underinflation) —
Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an overheated
tire
 Poor sealing of the tire bead
 Wheel deformation and/or tire separation
 A greater possibility of tire damage from road
hazards
High tire pressure (overinflation) —
Poor handling
 Excessive wear
 Uneven wear
 A greater possibility of tire damage from road
hazards

details, see “DOT and Tire Identification Number
(TIN)” on page 529.
3Location of the tread wear indicators: For
details, see “Checking and replacing tires” on
page 538.
4Tire ply composition and materials: Plies mean
a layer of rubber −coated parallel cords. Cords
mean the strands forming the plies in the tire.
5Radial tires or biasply tires: A radial tire has
“RADIAL” on the sidewall. A tire not marked with
“RADIAL” is a bias −ply tire.
6“TUBELESS” or “TUBE TYPE”: A tubeless tire
does not have a tube inside the tire. A tube type
tire has a tube inside the tire and the tube
maintains the air pressure.
7Load limit at maximum cold tire inflation
pressure: For details, see “Checking and
replacing tires” on page 538.
8Maximum cold tire inflation pressure: This
means the pressure to which a tire may be
inflated. For details about recommended cold tire
inflation pressure, see “Specifications” on page
518.
9Uniform tire quality grading: For details, see
“Uniform tire quality grading” that follows.
10Summer tire or all season tire: An all season
tire has “M+S” on the sidewall. The tire not
marked with “M+S” is a summer tire. For details,
see “Types of tires” on page 536.
