Rotating the tires
To equalize tire wear and extend tire life, Lexus recommends that tire rotation be
performed at the same interval as tire inspection.
Rotate the tires as shown in the illustration.
Make sure to perform wheel position registration procedure after rotating the tires.

Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced. Otherwise,
the tire may separate from the wheel, causing a loss of handling control.
Wheel selection
When replacing wheels, care should be taken to ensure that they are equivalent to
those removed in load capacity, diameter, rim width and inset
Replacement wheels are available at your Lexus dealer.
Lexus does not recommend using the following:
●
Wheels of different sizes or types
●
Used wheels
●
Bent wheels that have been straightened
INFORMATION
■
When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and transmit-
ters 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 pressure warning valves and transmitters must be
installed.
WARNING
■
When replacing wheels
●
Do not use wheels that are a different size from those recommended in the Owner’s
Manual, as this may result in a 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 accident, causing death or serious injury.
●
Use the correct wheel bolts for the wheels to be installed.
For details, contact your Lexus dealer.
■
Wheel bolts
Observe the following precautions to reduce the risk of death or serious injury:
●
Do not over tighten.
●
Never use oil or grease on the wheel bolts. Oil and grease may cause the wheel bolts
to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil
*1 :
Conventionally referred to as offset.
8-5. Tire maintenance
548
WARNING
or grease can cause the wheel bolts to loosen and the wheel may fall off, causing a
serious accident. Remove any oil or grease from the wheel bolts.
●
If there are any cracks or deformations in the wheel bolts, or if the surface treatment
becomes worn, have the wheel bolts replaced at your Lexus dealer. Failure to follow
these precautions could cause the wheel bolts to loosen and the tire to fall off, resulting
in death or serious injury.
■
Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an accident.
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 transmitters may not work properly with non-genuine
wheels.
Aluminum wheel precautions
Observe the following precautions when handling the aluminum wheels.
●
Use only Lexus wheel bolts and wrenches designed for use with your aluminum
wheels.
●
When rotating, repairing or changing your tires, check that the wheel bolts are
still tight after driving 621 miles (1000 km).
●
Be careful not to damage the aluminum wheels when using tire chains.
●
Use only Lexus genuine balance weights or equivalent and a plastic or rubber
hammer when balancing your wheels.

What to do if a problem occurs while driving
Using the emergency flashers to warn other drivers
Use the emergency flashers to inform other drivers of the presence of your vehicle
when it is stopped on the road, such as if the vehicle has broke down.
Press the switch.
All the turn signal lights will flash. To turn them off,
press the switch once again.
INFORMATION
■
Emergency flashers
●
If the emergency flashers are used for a long time with the engine stopped, the battery
may become discharged.
●
If any of the SRS airbags deploy (inflate) or in the event of a strong rear impact, the
emergency flashers will turn on automatically.
The emergency flashers will turn off automatically after operating for approximately
20 minutes. To manually turn the emergency flashers off, press the switch twice. (The
emergency flashers may not turn on automatically depending on the force of the
impact and conditions of the collision.)
Stopping the vehicle in an emergency
Stop the vehicle using the following procedure only in an emergency, such as if it
becomes impossible to stop the vehicle in the normal way:
WARNING
■
If the engine has to be stopped while driving
Power assist for the brakes and steering wheel will be lost, making the brake pedal harder
to depress and the steering wheel heavier to turn. Decelerate as much as possible before
stopping the engine.
1
Steadily step on the brake pedal with both feet and firmly depress it.
Do not pump the brake pedal repeatedly as this will increase the effort required to slow
the vehicle.

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.
Remain calm and follow the following.
●
If the door can be opened, open the door and exit the vehicle.
●
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 pressure outside of the vehicle
and then open the door after waiting for the rising water to enter the vehicle, and
exit the vehicle.
9-1. What to do if a problem occurs while driving
556
When the outside water level exceeds half the height of the door, the door cannot be
opened from the inside due to water pressure.
INFORMATION
■
Water level exceeds the floor
When the water level exceeds the floor and time has passed, the electrical equipment will
get damaged, the power windows will not operate, the engine stop, and the vehicle may
not be able to get moving.

WARNING
■
Caution while driving
Do not drive on roads where the roads may be submerged or the water may be rising.
Otherwise the vehicle may be damaged and cannot move, as well as become flooded
and set a drift, which may lead to death.
Operation of the fuel pump shut off system
When a certain level of impact is detected by an impact sensor due to a collision
and an airbag deploys or the engine is stopped, the fuel pump shut off system
operates to stop the supply of fuel and minimize the risk of fuel leakage.
