below. Please refer to the “Mainte-
nance” section of the Owner’s Manual
for a detailed description of inspection
procedures.
Every 30 Days At least once every 30 days, perform
these inspections:
• Check engine oil level using
the dipstick
• Visually check engine coolant
level on the see - t hrough reservoir

on the see-through reservoir
• Visually check condition
of battery
• Check level of windshield
washer fluid
• Check tire pressure
• Check tires for damage
and wear
• Check installation of driver’s
floor mat After a Car Wash • Check installation of driver’s
floor mat
After Off-Road Driving Whenever you drive off-road through
deep sand, mud or water, perform
these inspections daily:
• Check axle shaft boots
• Check ball joints and dust covers
• Check brake lines and hoses
• Check brake pads/rotors and
parking brake linings/drums
• Check differential oil
• Check engine air filter
• Check nuts and bolts on chassis
• Check steering linkage
and boots

e xplanation of Maintenance i te MS
MAINTENANCE Scheduled Maintenance Log72 Timing Chain
The timing chain requires no
periodic inspection.
Tire Rotation
See your Owner’s Manual for tire
rotation requirements. Check tire
pressure and check tires for damage
and uneven wear. If the vehicle is
equipped with a spare tire, check the
condition and pressure of the spare.
Tire-Pressure Warning Sensors
A tire-pressure sensor is mounted on
each full-size wheel. These sensors
do not require periodic maintenance.
When a sensor’s long-life lithium bat -
tery becomes discharged, the battery
should be replaced by a qualified
technician following procedures in
Lexus service and repair publications.
Transfer Case Oil
Check for correct oil level and
inspect each component for signs of
leakage. If you discover any leakage,
have it repaired immediately by a
qualified technician. For correct oil,
refer to your Owner’s Manual . Transmission
The transmission and transmission
fluid are a completely sealed unit.
Therefore, periodic checks and
replacement of the transmission
fluid are not required, and there is
no dipstick on the transmission.
Any repairs that require adding or
replacing fluid should be performed
by a qualified technician following
procedures in Lexus service and
repair publications.
Wiper Blades
The wiper blades should not show
any signs of cracking, splitting, wear,
contamination or deformation. The
wiper blades should clear the wind -
shield without streaking or skipping.
