2-4. Using other driving systems
CAUTION
nWhen the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-
tor light flashes and a buzzer sounds.
nWhen the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to ensure vehicle stability and driving force, do not turn the
TRAC/VSC systems off unless necessary.
nReplacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level.
The ABS and VSC systems will not function correctly if different tires are installed
on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
nHandling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect the driv-
ing assist systems, and may cause a system malfunction.

256
2-5. Driving information
nTire chain installation
Observe the following precautions when installing and removing chains:
lInstall and remove tire chains in a safe location.
lInstall tire chains on the front tires only. Do not install tire chains on the rear tires.
lInstall the tire chains on front tires as tightly as possible. Retighten chains after
driving 1 /4 ⎯ 1/2 mile (0.5 ⎯ 1.0 km).
lInstall tire chains following the instructions provided with the tire chains.
CAUTION
nDriving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or serious
injury.
lUse tires of the size specified for your vehicle.
lMaintain the recommended level of air pressure.
lDo not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires
being used.
lUse snow tires on all, not just some wheels.
nDriving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
lDo not drive in excess of the speed limit specified for the tire chains being used,
or 30 mph (50 km/h), whichever is lower.
lAvoid driving on bumpy road surfaces or over potholes.
lAvoid sudden turns and braking, as use of chains may adversely affect vehicle
handling.
lSlow down sufficiently before entering a curve to ensure that vehicle control is
maintained.

When driving
NOTICE
nRepairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
nFitting tire chains
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.

4-3. Do-it-yourself maintenance
Tires
Replace or rotate tires in accordance with maintenance schedules and
treadwear.
nChecking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear indi-
cators is shown by the “TWI” or
“∆” marks, etc., molded on the
sidewall of each tire.
Check spare tire condition and
pressure if not rotated.
nTire rotation
Vehicles with a compact spare tire
Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Lexus recommends that
tire rotation is carried out at the
same interval as tire inspection.
Vehicles with a full-size spare tire
Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Lexus recommends that
tire rotation is carried out at the
same interval as tire inspection.

Maintenance and care
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and the tire pressure warning
system must be initialized. Have the tire pressure warning valve and
transmitter ID codes registered by your Lexus dealer. (→P. 4 8 1 )
Initializing the tire pressure warning system
nThe tire pressure warning system must be initialized in the following
circumstances:
lWhen the tire inflation pressure is changed such as when changing
travelling speed or load weight
lWhen changing the tire size
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
nThe tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise. (→P. 537, 545)
