3985-6. Driving tips
5-6.Driving tips
Use fluids that are appropriate to
the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Power control unit coolant
• 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 same size
and brand, and that chains match the
size of the tires.*
*: Tire chains cannot be mounted on
vehicles with 235/55R19 tires.
Winter driving tips
Carry out the necessary prepa-
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
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 serious injury.
OUse tires of the specified size.
OMaintain the recommended level of air pressure.
ODo not drive at speeds in excess of the speed limit or the speed limit specified for the snow tires being
used.
OUse snow tires on all, not just some
wheels.
QDriving with tire chains (except
235/55R19 tires)
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehi- cle 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 50 km/h (30 mph), whichever is lower.
OAvoid driving on bumpy road sur-faces or over potholes.
OAvoid sudden acceleration, abrupt steering, sudden braking and shift-
ing operations that cause sudden engine braking.
OSlow down sufficiently before enter-ing a curve to ensure that vehicle control is maintained.
ODo not use LTA (Lane Tracing Assist) system (if equipped).
NOTICE
QRepairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer 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.

Maintenance and care
WARNING
QWhen working on the engine compartment
OMake sure that “IGNITION ON” on the multi-information display and the “READY” indicator are both off.
OKeep hands, clothing and tools away from the moving fan.
OBe careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other flu-ids may also be hot.
ODo not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
ODo not smoke, cause sparks or
expose an open flame to fuel. Fuel fumes are flammable.
OTake care because brake fluid can harm your hands or eyes and dam-age painted surfaces. If fluid gets
on your hands or in your eyes, flush the affected area with clean water immediately. If you still experience
discomfort, consult a doctor.
QWhen working near the electric
cooling fan or radiator grille
Be sure the power switch is off. With the power switch in ON, the
electric cooling fan may automatically start to run if the air conditioning is on and/or the coolant temperature is
high. ( P.458)
QSafety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc., from getting in your eyes.
NOTICE
QIf you remove the air cleaner fil-ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
QIf the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill- ing, it may indicate a serious problem.
