Hi there,

I have a 2013 RX 350 AWD and I'm wondering if it is equipped with hill assist. If so, how does it wor?. On my other ride (Q50), the car won't roll backwards on a hill if I let go of the brake. Thanks!

JDR76

When you are at a stop, push down hard on your brake pedal. It'll beep and the (If I remember correctly) traction control light will illuminate while the feature is activated.

The feature that JDR76 is referring to is the 'Hill Start Assist" that basically "keeps your foot on the brake" for 2 seconds so the car isn't rolling during the time it takes for you to lift your foot off the brake and step on the gas pedal. It's the same concept as pulling up on the e-brake of a manual transmission car and slowly releasing it as you engage the clutch and start off.

...it also comes with a user's manual.

Hill-start assist control helps to prevent the vehicle from rolling backwards
when starting on an incline or slippery slope.
To engage hill-start assist control,
further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is activated.
The slip indicator will also start
flashing
.
●While hill-start assist control is operating, the brakes remain automatically
applied after the driver releases the brake pedal. The stop lights and the high
mounted stoplight turn on.
●Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
●If the slip indicator does not flash and the buzzer does not sound when the brake
pedal is further depressed, slightly reduce the pressure on the brake pedal (do
not allow the vehicle to roll backward) and then firmly depress it again. If the system
still does not operate, check if the operating conditions explained above
have been met.

●In the following situations, hill-start assist control will be canceled and the
buzzer will sound twice.
• No attempt is made to drive the vehicle within approximately 2 seconds of
releasing the brake pedal.
• The shift lever is moved to P.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.
●If a buzzer other than the hill-start assist control buzzer is sounding, the hill-start
assist control buzzer may not sound when the system is activated or canceled.

dang I just had traction control light start blinking at the light two days ago and I took the car to a Lexus dealer. They stated that this is an Auto Hold feature, but then could not fully explain why this goes off and the car starts rolling after 2-3 seconds. Thanks guys!
