Tire Pressure Warning On Rx400H?

[whole9yards]

Hi all, just picked up my 400h yesterday, loving it to bits!! Going through the manual, there doesn't seem to be anything about tire pressure monitoring system warning? I know 2006 RX don't have them, but this is a 2009 reg exec Limited Edition. Could anyone please shed a light on this? I even had it on my 05 GS 300! And I wouldn't really feel safe driving it without it...

Many thanks in advance!

if it's not in the manual then I guess if doesn't have it. The system was fitted to later vehicles in the US, I guess not in the UK.

There are aftermarket options available if you feel that strongly about it, cost around £100 to £150 plus the cost of fitting the sensors in the wheels and rebalancing.

That's really diappointing... How would you know if you have a slow leaking puncture?

Thanks Colin!

Manually check your tyre pressures. Personally I never trust a system to tell me when my tyres are low. Takes me 10 seconds a wheel to check and I should do it every day but I only manage to do it every 2-3 days.

Thanks for the reply! Being a new driver, would you mind sharing with me how you check the pressure manually? Is it just by looking? I thought I have to get to the petrol station to check using their free tire pressure test thingy. I am more worried about if I get a puncture on the motorway, without the TPMS, it's impossible to know you are in trouble!

_{Buy a tyre pressure gauge from Halfords - it is child's play to use and far more reliable than these in-built options.}

_{However, how come you are now a "new driver", above you refer to " I even had it on my 05 GS 300! And I wouldn't really feel safe driving it without it...}

_{". Seems rather like a contradiction.}

_{If you get a puncture on a motorway, you will not need a tyre pressure gauge, it will look rather flat and the handling will tell you.}

Thanks Duncan! I got my GS last month, it was my first ever car! I upgraded to RX 400h last week as I felt the GS wasn't big enough and the RX seems too good of a deal to pass up :)

Thanks for your advice. Will look into that gauge from Halfords.

I got a pen type tyre pressure gauge from eBay for £2 and it also came with a tyre tread depth gauge. Remove valve cap (if unlike me you have some left on the car) press onto valve, read pressure and repeat 3 more times.
