I RENTED A 2018 TOYOTA SIENNA ON A RECENT TRIP TO HAWAII. UNLIKE EARLIER SIENNA MODELS (WHICH HAD BOLDER, THICKER LABELS FOR THE INDICATORS), THE INSTRUMENT PANEL WAS VERY FAINT AND HARD TO READ IN DAYLIGHT. IN SHADE, IT WAS ALMOST INVISIBLE. I CHECKED THE MANUAL TO SEE IF I COULD TURN THE BRIGHTNESS UP, BUT IT APPEARS TO HAVE BEEN DESIGNED THIS WAY. I'M CONCERNED THAT NOT BEING ABLE TO SEE THE INSTRUMENT PANEL TO OBSERVE SPEED OR OTHER INFORMATION COULD CAUSE AN ACCIDENT, ESPECIALLY IF YOU HAVE TO TAKE YOUR EYES OFF THE ROAD BECAUSE IT'S SO HA…

I HAVE A QUESTION REGARDING VEHICLE SEAT MOVEMENT. I HAVE BEEN TOLD BY TWO DEALERSHIPS THAT THE SEATS IN THE THIRD ROW OF THE TOYOTA SIENNA ARE MEANT TO HAVE SOME PLAY TO THEM. MY MAIN CONCERN IS THAT WITH A COUPLE OF CAR SEATS IN THE THIRD ROW, OR A COUPLE OF PASSENGERS, THE MOVEMENT OF THE SEATS MAY BE AN ISSUE. ALL FOUR SEAT LATCHES ROTATE WHEN LIFTING ON THE SEAT BY HAND, ALLOWING THE SEAT TO TWIST, MOVE TO THE REAR OF THE VEHICLE AND MOVE LATERALLY.
