4-6. Driving tips
Driving
Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
•Engine coolant
• Power control unit coolant (LC500h)
•Washer fluid
 Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
 Tire chains can only be installed on
the rear tires. However, tire chains
cannot be installed on 275/35RF21
or 275/40RF20 rear tires.
Before installing tire ch ains, change all four
tires and wheels to those of the specified
size for use with tire chains (front tires:
245/45RF20, rear tires: 245/45RF20,
wheels: 20 x 8 1/2 J 25 inset). Use the
specified type of tire chains and install
them on the rear tires only.
For details, contact any authorized Lexus
retailer or Lexus authorized repairer, or
any reliable repairer.
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.

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
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), which-
ever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.

WARNING
■When installing the tire
Failure to follow these precautions could cause the wheel nuts to loosen and the tire to fall off, resulting in death or serious
injury.
●Never use oil or grease on the wheel bolts or wheel nuts.Oil and grease may cause the wheel
nuts to be excessively tightened, lead- ing to bolt or disc wheel damage. In addition, the oil or grease can cause
the wheel nuts to loosen and the wheel may fall off, causing a serious accident. Remove any oil or grease from the
wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 140 N•m (14.3 kgf•m, 103.3 ft•lbf) as soon as possible
after changing wheels.
●Do not attach a heavily damaged wheel ornament, as it may fly off the wheel while the vehicle is moving.
●When installing a ti re, only use wheel
nuts that have been specifically designed for that wheel.
●If there are any cracks or deformations in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle inspected by any authorized Lexus retailer or Lexus authorized repairer,
or any reliable repairer.
■After using the tools and jack
Before driving, make sure all the tools and jack are stored securely in place. Failure to do so may cause injury in case
of a collision or sudden braking.
