2604-6. Driving tips
Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine coolant/power control unit cool-
ant
•Washer fluid
 Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the front tires.
*
Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires.
*: Tire chains cannot be mounted on vehi-
cles with 18-inch/19-inch tires.
Perform the following according to the
driving conditions:
 Do not try to forcibly open a window
Winter driving tips
Carry out the necessary prepara-
tions and inspection s before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
QDriving 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.
OUse tires of the specified size.
OMaintain the recommended level of air
pressure.
ODo not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
OUse snow tires on all, not just some
wheels.
QDriving with tire chains (vehicles with
17-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.
ODo not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
OAvoid driving on bumpy road surfaces
or over potholes.
OAvoid sudden acceleration, abrupt
steering, sudden braking and shifting
operations that cause sudden engine
braking.
OSlow down sufficiently before entering
a curve to ensure that vehicle control
is maintained.
ODo not use LTA (Lane Tracing Assist)
system.
NOTICE
QRepairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.

or auto parts store for information
concerning recycling or disposal.
ODo not leave used engine oil within the
reach of children.
NOTICE
QTo prevent serious engine damage
Check the oil level on a regular basis.
QWhen replacing the engine oil
OBe careful not to spill engine oil on the
vehicle components.
OAvoid overfilling, or the engine could
be damaged.
OCheck the oil level on the dipstick
every time you refill the vehicle.
OBe sure the engine oil filler cap is prop-
erly tightened.

QCoolant selection
Only use “Toyota Super Long Life Coolant”
or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite,
and non-borate coolant with long-life
hybrid organic acid technology.
U.S.A.:
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. (Minimum temperature: -31°F [-
35°C])
Canada:
“Toyota Super Long Life Coolant” is a mix-
ture of 55% coolant and 45% deionized
water. (Minimum temperature: -44°F [-
42°C])
For more details about coolant, contact
your Lexus dealer.
QIf the coolant level drops within a short
time of replenishing
Visually check the radiator, hoses,
engine/power control unit coolant reser-
voir caps, drain cock and water pump.
If you cannot find a leak, have your Lexus
dealer test the cap and check for leaks in
the cooling system.
Check the radiator and condenser and
clear away any foreign objects.
If either of the above parts is extremely
dirty or you are not sure of their condi-
tion, have your vehicle inspected by
your Lexus dealer.

WARNING
QWhen the hybrid system is hot
Do not remove the engine/power con-
trol unit coolant reservoir caps or the
radiator cap. ( P.398)
The cooling system may be under pres-
sure and may spray hot coolant if the cap
is removed, causing serious injuries, such
as burns.
NOTICE
QWhen adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mixture
of water and antifreeze must be used to
provide proper lubrication, corrosion
protection and cooling. Be sure to read
the antifreeze or coolant label.
QIf you spill coolant
Be sure to wash it off with water to pre-
vent it from damaging parts or paint.
