Lexus Cabin Air Filter
Lexus Cabin Air Filter
Also known as an A/C filter – is the equivalent of your home air conditioning units filter, but for your car. Filters the air as it passes through the air conditioning (and heating) system.
Service Interval: 30k-50k
Pretty straightforward here, the more you use the heating and cooling system, the more contaminants are caught here. You can remove the filter and look at it, though flow may be restricted even with a clean appearing filter.

Lexus Air Filter FAQ
Lexus Air Filter FAQ
Typically in a black box next to the engine, under the hood. Keeps the air entering the engine clean.
Service Interval: 12k-30k
Air filters may become restricted with dust and still look relatively clean. Simply knocking the dust out of it does not help this matter.

Lexus Transfer Case
Transfer Case
Transfers the power from the transmission/transaxle to the front and rear axles of a 4WD and many AWD vehicles.
Service Interval: 15k-100k, some vehicles, never (inspect only)
Service Interval varies greatly depending on the type of driving you do. Under extreme conditions, some vehicles actually call for every 15k miles, while under normal driving conditions, some never suggest fluid replacement. To inspect, check fluid levels based on your vehicles configuration. Breakdown of the fluid may not be apparent, but if the fluid is notably dirty, it should be replaced.

Lexus Differential FAQ
Lexus Differential
Attached to your transmission (in FWD cars) and is in the center of the drive axle in RWD cars. 4WD/AWD vehicles will have differentials in the front and rear, as well as a center differential and/or transfer case.
Service Interval: 12k-30k, some vehicles, never (inspect only)
Service Interval varies greatly depending on the type of driving you do. Under extreme conditions, some vehicles actually call for every 12k miles, while under normal driving conditions, some never suggest fluid replacement. Some FWD vehicles include the differential fluid as part of the transaxle fluid. To inspect, check the fluid level. Breakdown of the fluid may not be apparent, but if the fluid is notably dirty, it should be replaced.

Lexus Automatic Transmission Fluid
Automatic Transmission Fluid FAQ
Pumped through the transmission and torque converter – responsible for heat dissipation, lubrication and protection
Service Interval: 15k-100k
Manufacturers vary greatly in service recommendations. Some suggest a drain and fill (only replacing 3 or so of the 9-12 quarts in the system), some a drain and fill with filter replacement, and some a full transmission fluid exchange. On vehicles that have a dipstick, the fluid should be relatively bright red in color and not have a burnt smell. If it is very dark or smells burnt, proceed with caution as noted below.

Lexus Coolant FAQ
Flows from the engine to the radiator and back again, transferring heat from the Lexus engine to the ambient air. Protects internal engine components.
Service Interval: 30k-150k or 2 years to 6 years
Typical green ethylene glycol coolants are good for 2 years or 30k miles. Other coolants will have longer service intervals. Use a hygrometer to test for freeze/boilover point. Add, remove or replace as needed to ensure proper protection. A voltmeter with the positive lead in the coolant (open the radiator cap) and the negative lead to an engine ground will show voltage. If the voltage is more than about one half of a volt, then there is a voltage problem and most likely a galvanic reaction is occurring in the coolant system.

Lexus spark plug replacement chart
Lexus spark plug replacement
Gasoline engines need three things to run – fuel, compression (of air or a gas containing oxygen) and spark, these take care of the spark.
Typical Service Interval: 30k, 60k, 90, 100k, 110k, 120k
Typically, if a vehicle is equipped with copper spark plugs, it has a service interval of 30k. Double Platinum (platinum on both ground strap and electrode) tipped plugs have a 60k service interval. Iridium Plugs have 90k to 110k service intervals. In most applications, these are interchangeable and the main consideration is effective service life. In general, Platinum and Iridium tipped plugs cannot be gapped, however copper plugs can. Simply cleaning plugs does little to help them and if you are going to pull them to inspect them, you might as well replace them at the same time.

VIDEO: Lexus LF-LC Concept
Today Lexus unveiled its LF-LC concept at the Detroit Auto Show.
The dynamic cabin lines are carried through to the rear deck, sculpturally integrating the spindle grille theme to echo the front of the vehicle while creating a unique sense of width. The tail lamps, inspired by the look of a jet afterburner at take-off, use inner lighting to create a remarkable sense of depth. The rear is also fitted with fog lamps, repeating the fading dot matrix pattern of the front fog lamps. Visually, the integrated tail and fog lamps repeat the “L” shape and lead the viewer’s eye down to the powerful Lexus quad exhaust.
