2-4. Using other driving systems
IS F_EE
CAUTION
If the hill- start assist control does not operate effectively
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered in ice.
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving
may cause an accident, resulting in death or serious injury. Exercise particu-
lar care when the indicator light flashes.
When TRC and VSC are off
Be especially careful and drive at a speed appropriate to the road conditions.
As these are systems to help enhance vehicle stability and driving force, do
not turn off TRC and VSC unless necessary.
Replacing tires
Make sure that all tires are of the designated size and total load capacity, and
of the same brand and tread pattern. In addition, make sure that the tires are
inflated to the recommended tire pressure level.
The ABS, VSC and TRC systems will not function correctly if different
tires are fitted on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, for further information when replacing tires or
wheels.
Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will
affect the driving assist systems, and may cause the system to malfunction.

Tire chain installation
Observe the following precautions when installing and removing chains.
Install and remove tire chains in a safe location.
Install tire chains on the rear tires.
Install tire chains following the instructions provided in the accompany-
ing manual.
CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Use snow tires on all, not just some wheels.
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden turns and braking, as use of chains may adversely affect
vehicle handling.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

NOTICE
Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot holes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
Low profile tires
Low profile tires may cause greater damage than usual to the tire wheel
when receiving impact from the road surface. Therefore pay attention to the
following:
Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
Avoid pot holes, uneven pavement, curbs and other road hazards.
Failure to do so may lead to severe tire and wheel damage.
If tire inflation pressure becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent refilling, have it checked by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Instructions for checking tire pressure
When checking tire inflation pressure, observe the following:
Check 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, you will get an accurate cold tire
inflation pressure reading.
Always use a tire pressure gauge.
The appearance of the tire can be misleading. In addition, tire inflation
pressures that are even just a few pounds off can degrade ride and han-
dling.
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 placed so that the vehicle is
balanced.
Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However, Lexus
recommends that tire inflation pressure be checked once every two
weeks.
