Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
● Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
• Have a service technician inspect the level and specific gravity
of battery electrolyte.
● 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 pressure falls in winter as the outside temperature falls. Add
2.9 to 4.3 psi (20 to 30 kPa, 0.2 to 0.3 kgf/cm2 or bar) to the
standard tire inflation pressure.

■ Checking the engine oil
Park the vehicle on level ground. After turning off the hybrid sys-
tem, wait more than five minutes for the oil to drain back into the
bottom of the engine.
Hold a rag under the end and pull
the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end, pull the dipstick out and check the

■ Adding engine oil
If the oil level is below or near the
low level mark, add engine oil of
the same type as already in the
engine.
Make sure to check the oil type and prepare the items needed before
adding oil. Remove the oil filler cap.
Add engine oil slowly, checking the dipstick.
Install the filler cap, turning it clockwise.
It takes about 1.6 qt. (1.5 L, 1.3 lmp. qt.) to raise the oil level from low to full on the
dipstick.

■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the quality of the
oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and frequent
acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumption, keep in mind that the oil may have
become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per 1000
km)
●If you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles (1000 km),
contact your Lexus dealer.
■After changing the engi ne oil (U.S.A. only)
The oil change system should be reset. Perform the following procedures: Switch the display to the odometer. ( →P. 1 4 3 )
