The button only turns the system on
control of the cruise control is by a number of sensors and switches
brake sensor , clutch (if manual) VSS (if auto)
tacho, ECM, Speedo (road speed ) all of which have to word as any one not working will not allow the cruise control to work
run the fault codes and take it to an accredited service center for testing

The Lexus Hybrid RX400h seems to be running more of engine now rather then electric power. Used to be when start engine, vehicle can move a distance on battery power before engine kicks in. Now engine...


If the engine is running more often I would be checking the condition of the batteries. The whole idea is to run on the batteries until the voltage becomes too low in which case the engine starts. Take it back to the dealer service department for a diagnosis of the problem.

Traction problem with 2008 lexus rx 400h


Hello Steve Smith,

Assuming your LUG NUTS are torqued properly...

The issue COULD have been caused when your
tires & wheels were remounted... BUT you should
have has Traction (or STABILITY) and ABI LIGHTS
almost immediately... (means tire shop)

Else...
One or more of your Wheel sensors has been
moved enough to provide MARGINAL operation.

In any case the PURCHASE PRICE of these
sensors is NOT cheap...

I'd suggest you SCAMPER quickly back
to your TIRESHOP... and come to an
UNDERSTANDING (who done it = who pays).

Get your codes (DTC) read to see if your car
knows WHAT is up.

In my opinion

Hi, I need to install a european country map in my RX400h. How do we do this


Open the rear hatch and the spare TIRE AND TOOL COVER area. You should see a small DVD player nestled under a protective frame.
In the RX350 it is to the right of the tire,in the 5 o`clock position. The 400h should be similar but perhaps slightly different position, due to Hybrid equipment.
You will need the ignition power on to press the eject and load buttons. Save your old DVD for future use if returning to North America.
Post back to confirm location and how you make out

My 2007 lexus hybrid mileage just rolled over 27,000 miles. The same day the icon of 'engine' check came on. Are they related?


Yea it's built in the computer, from the factory, so that every 27,000 to 30,000 mile you take it in for service..

Hi, need to troubleshoot my A/C system, do you have the interface for the electric air compressor?


2008 should be under warranty, why not let an experienced tech with the proper equipment diagnos that. the electric components on the hybrids are touchy and should be masintaine and repaired by a trained tech. you dealer can help you with this.
