Lexus LX / Lexus LX Owners Manuals / Owner amenities / Explanation of maintenance items

The following descriptions are provided to give you a better understanding of the maintenance services that should be performed on your vehicle.

The scheduled maintenance log indicates at which time/mileage intervals each service should be performed.

Please note that many maintenance services should be performed only by a qualified technician.

For further information on maintenance services that you can perform yourself, see the maintenance sections of your Owner’s Manual.

Active Height Control System
Inspect the lines, accumulators and pump and replace the system fluid when specified. For recommended fluid, refer to your Owner’s Manual.

Air Conditioner Filter
Clean or replace at specified intervals.

More frequent cleaning or replacement may be required when driving in dusty conditions, heavy traffic areas, urban areas, desert areas or dirt roads. Refer to your Owner’s Manual for service details.

Axle Shaft Boots
Check the axle shaft boots and clamps for cracks, deterioration and damage. Replace any damaged parts and, if necessary, repack the grease.

A qualified technician should perform these operations.

Ball Joints and Dust Covers
Check the suspension and steering linkage ball joints for looseness and damage. Check all dust covers for deterioration and damage. A qualified technician should perform these inspections.

Body Inspection
Visually check for corrosion, scratches and other damage. Check outer body panels, inner panels of the hood and doors, and underneath the vehicle.

Apply touch-up paint to any chips and scratches or have them repaired by a qualified technician.

Brake Fluid
Replace using fluid type specified in your Owner’s Manual. A qualified technician should perform this operation.

Brake Lines and Hoses
Visually inspect for proper installation.

Check for chafing, cracks, deterioration and signs of leakage. Replace any deteriorated or damaged parts.

A qualified technician should perform these operations.

Brake Pads, Calipers and Rotors
Check brake pads and rotors for excessive wear; check brake rotors for runout. Check brake calipers for fluid leakage. A qualified technician should perform these inspections.

Differential Oil
Check for correct oil level and inspect each differential component for signs of leakage. If you discover any leakage, have it repaired immediately by a qualified technician. Refer to your Owner’s Manual for fluid specifications.

Drive Belt
Inspect for cracks, excessive wear and oiliness. Check the belt tension and adjust if necessary. Replace the belts if they are damaged.

Drive Shaft
Lubricate the drive shaft spiders and slide yokes with lithium-base chassis grease and the double cardan joint with molybdenum-disulfide lithiumbase chassis grease, and re-torque the flange nuts and bolts. Only a qualified technician should re-torque the flange nuts and bolts. If vehicle is submerged, lubricate within 24 hours, regardless of maintenance interval.

Driver’s Floor Mat
• Only use the driver’s floor mat designed specifically for the model and model year of your vehicle, such as Lexus Genuine floor mats.
• Always properly secure the driver’s floor mat using the retaining hooks.
• Never install another floor mat on top of the existing driver’s floor mat.
• Never install the driver’s floor mat upside down.

Engine Air Filter
Check for excessive dirt, damage and oiliness. Replace if necessary.

Engine Coolant
When inspecting, visually check the engine coolant level on the seethrough reservoir. Add coolant as necessary. When replacing, drain the cooling system and refill with coolant. Always use Genuine Toyota Super Long-Life Coolant or similar high-quality non-silicate, non-amine, non-nitrate, non-borate ethyleneglycol coolant with long-life hybrid organic acid technology (i.e., a combination of low phosphates and organic acids). A qualified technician should perform these operations.

Check the radiator and condenser for blockage by leaves, dirt or insects and clean if necessary. Also check the hose connections for corrosion and condition of installation.

Note: Initial replacement is at 120 months/100,000 miles. Replace every 60 months/50,000 miles thereafter.

Engine Oil and Oil Filter
Replace the oil filter and drain and refill the engine oil at specified intervals.

SAE 0W-20 oil is the best choice for good fuel economy and good starting in cold weather. If SAE 0W-20 is not available, SAE 5W-20 may be used; however, it must be replaced with SAE 0W-20 at the next oil change. See your Lexus dealer for oil specifically formulated for your vehicle’s engine. For instructions on how to reset the reminder light, refer to your Owner’s Manual.

Note: If you do the majority of your driving under any of the special operating conditions indicated on page 44, you should replace the engine oil and oil filter every six months or 5,000 miles, regardless of the oil used or the certification of the vehicle.

Exhaust Pipes and Mountings
Visually inspect the exhaust pipes, muffler and hangers for cracks, deterioration and damage. Start the engine and listen carefully for any exhaust leakage. Tighten connections and replace parts as necessary.

Fuel Lines and Connections, Fuel Tank Band and Fuel Tank Vapor Vent System Hoses
Visually inspect for corrosion, damage, cracks, and loose or leaking connections. Tighten connections and replace parts as necessary.

Fuel Tank Cap Gasket
Visually inspect for cracks, deterioration and damage and replace if necessary.

Nuts and Bolts on Chassis
Check that tightness of the seatmounting bolts and front/rear suspension- member retaining bolts matches torque measurements specified in the Repair Manual.

Power Steering Fluid
When inspecting, visually check the power steering fluid level on the seethrough reservoir. Add fluid as necessary.

For fluid specifications, refer to your Owner's Manual.

Rack and Pinion Assembly
Inspect the rack and pinion assembly for signs of leakage, damage and loose electrical connections. Tighten connections and if you discover any leakage or damage, have it repaired immediately by a qualified technician.

Road Test
While driving the vehicle, check for proper operation of engine, transmission, brakes and steering. Also check the parking brake, and check for abnormal noise or vibration from any part of the vehicle.

Spark Plugs
Replace at specified interval. Install new plugs of the same type as originally equipped (see your Owner’s Manual). A qualified technician should perform this operation.

Steering Linkage and Boots
With the vehicle stopped, check for excessive freeplay in the steering wheel. Inspect the linkage for bending and damage and the dust boots for deterioration, cracks and damage.

Replace any damaged parts. A qualified technician should perform these operations.

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 battery 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 precedures in Lexus service and repair publications.

If your name or address has changed or if you purchased your Lexus as a used vehicle, please complete and mail the attached card, even if your warranty coverage has expired.
