IS300h_EE(OM53B95E)
CAUTION
The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded (such as exces-
sively worn tires on a snow covered road).
The vehicle hydroplanes while driving at high speed on wet or slick roads.
Stopping distance when the ABS is operating may exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations:
When driving on dirt, gravel or snow-covered roads
When driving with tire chains
When driving over bumps in the road
When driving over roads with potholes or uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
Hill- start assist control does not operate effectively when
Do not overly rely on hill-start assist control. Hill-start assist control may not
operate effectively on steep inclines and roads covered with ice.
Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use hill-
start assist control to hold the vehicle on an incline, as doing so may lead to an
accident.
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC/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 TRC/VSC systems off unless necessary.
Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed 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 the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

3124-6. Driving tips
IS300h_EE(OM53B95E)
Park the vehicle and move the shift lever to P without setting the parking
brake. The parking brake may freeze up, preventing it from being
released. If necessary, block the wheels to prevent inadvertent sliding or
creeping.
Except vehicles with 18-inch tires
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(3 mm [0.12 in.] in diameter)
Cross chain
(4 mm [0.16 in.] in diameter)
Vehicles with 18-inch tires
Tire chains cannot be mounted on the 18-inch tires.
Snow tires should be used instead.
Regulations regarding the use of tire chains vary depending on location
and type of road. Always check local regulations before installing chains.
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. Do not install tire chains on the front tires.
Install tire chains on rear tires as tightly as possible. Retighten chains after driv-
ing 0.5  1.0 km (1/4  1/2 mile).
Install tire chains following the instructions provided with the tire chains.

CAUTION
Driving 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 seri-
ous 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 specified
for the snow tires being used.
Use snow tires on all, not just some wheels.
Driving with tire chains (except vehicles with 18-inch tires)
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.
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 acceleration, abrupt steering, sudden braking and shifting oper-
ations that cause sudden engine braking.
Slow down sufficiently before entering a curve to ensure that vehicle control
is maintained.
Do not use LDA (Lane Departure Alert) system.
NOTICE
Repairing 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.
Fitting tire chains (except vehicles with 18-inch tires)
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
