When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset
*
.
Replacement wheels are available at
your Lexus dealer.
*
: Conventionally referred to as offset.
Lexus does not recommend using the
following:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straight-
ened
■
When replacing wheels
The wheels of your vehicle are equipped
with tire pressure warning valves and trans-
mitters that allow the tire pressure warning
system to provide advance warning in the
event of a loss in tire inflation pressure.
Whenever wheels are replaced, tire pres-
sure warning valves and transmitters must
be installed. (
Use only Lexus wheel nuts and
wrenches designed for use with
your aluminum wheels.
When rotating, repairing or chang-
ing your tires, check that the wheel
nuts are still tight after driving 1000
miles (1600 km).
Be careful not to damage the alumi-
num wheels when using tire chains.
Use only Lexus genuine balance
weights or equivalent and a plastic
or rubber hammer when balancing
your wheels.
Wheels
If a wheel is bent, cracked or heavily
corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel or cause a loss of
handling control.
Wheel selection
WARNING
■
When replacing wheels
●
Do not use wheels that are a different
size from those recommended in the
loss of handling control.
●
Never use an inner tube in a leaking
wheel which is designed for a tubeless
tire. Doing so may result in an acci-
dent, causing death or serious injury.
NOTICE
■
Replacing tire pressure warning
valves and transmitters
●
Because tire repair or replacement
may affect the tire pressure warning
valves and transmitters, make sure to
have tires serviced by your Lexus
dealer or other qualified service shop.
In addition, make sure to purchase
your tire pressure warning valves and
transmitters at your Lexus dealer.
●
Ensure that only genuine Lexus wheels
are used on your vehicle.
Tire pressure warning valves and trans-
mitters may not work properly with
non-genuine wheels.

If the door cannot be opened, open
the window using the power window
switch and ensure an escape route.
If the window can be opened, exit
the vehicle through the window.
If the door and window cannot be
opened due to the rising water,
remain calm, wait until the water
level inside the vehicle rises to the
point that the water pressure inside
of the vehicle equals the water pres-
sure outside of the vehicle and then
open the door after waiting for the
rising water to enter the vehicle, and

wheel heavier to turn. Decelerate as
much as possible before turning off the
engine.
If the vehicle is submerged
or water on the road is rising
This vehicle is not designed to be
able to drive on roads that are
deeply flooded with water. Do not
drive on roads where the roads may
be submerged or the water may be
rising. It is dangerous to remain in
the vehicle, if it anticipated that the
vehicle will be flooded or set a drift.

If your vehicle needs to be
towed
If towing is necessary, we recom-
mend having your vehicle towed by
your Lexus dealer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.
Use a safety chain system for all
towing, and abide by all state/pro-
vincial and local laws.
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■
When towing the vehicle
Be sure to transport the vehicle with all
four wheels raised off the ground. If the
vehicle is towed with the tires contacting
the ground, the drivetrain and related
parts may be damaged or an accident
may occur due to a change in direction
of the vehicle.
■
While towing
●
When towing using cables or chains,
avoid sudden starts, etc. which place
excessive stress on the towing eyelets,
cables or chains. The towing eyelets,
cables or chains may become dam-
aged, broken debris may hit people,
and cause serious damage.
●
Do not turn the engine switch off.
There is a possibility that the steering
wheel is locked and cannot be oper-
ated.
■
Installing towing eyelets to the vehi-
cle
Make sure that towing eyelets are
installed securely.
If not securely installed, towing eyelets
may come loose during towing.
NOTICE
■
To prevent damage to the vehicle
when towing using a wheel-lift type
truck
●
Do not tow the vehicle from the rear
when the engine switch is off. The
steering lock mechanism is not strong
enough to hold the front wheels
straight.
●
When raising the vehicle, ensure ade-
quate ground clearance for towing at
the opposite end of the raised vehicle.
Without adequate clearance, the vehi-
cle could be damaged while being
towed.
■
To prevent damage to the vehicle
when towing with a sling-type truck
Do not tow with a sling-type truck, either
from the front or rear.
■
To prevent damage to the vehicle
during emergency towing
Do not secure cables or chains to the
suspension components.
