What??? This light MUST be a joke. Right???
Thanx, Gary (SumNewGui)

 

Series 4? Yeah just ignore it...

 

there are 2 settings.....gas saver mode and redline.......

 

I've seen those on S4s. How do you change the settings?

 

PS: I was driving a friend's S4 TII.

It kept saying "Shift UP" on the highway when I was in 5th.
I take it Mazda did not put much effort into the creation of said shift light.

 

it is already preset......2 settings...u don't change much....my 88 GXL had it.

 

When youre driving around at a constant speed, it will tell you to shift at 2500 RPM, but when you're accelerating, it won't turn on unitl past 3k RPM.

I use it when I need to save gas.

 

Mazda used it to signal the driver to shift to get the best gas mileage.
This was used to verify to CAFE that the car did hit the target gas mileage as released by Mazda.

SHIFT UP light triggered in 5th gear?
Your 5th gear / reverse switch is disconnected or dead.

Hw do I change the mode? Thanx

 

You don't,

And for the others in this thread.. it was common on other sports cars of the time to have the shift up light... cars like the 944 and 944 Turbo or VW GTI VR6...

 

or ne other manual car from that time.... my vw rabbit had it. the vw it was a real joke because if you followed it ur engine would stall. is my s4's shift up light not working right? cause it tells me to shift at 2800 under normal conditions and 3600 under hard acceleration.

 

Mine didn't work until I swapped out my clutch, then all of a sudden I was like "what the hell is that?" I now wish I had yanked the bulb when I had the dash apart to put my new gauge faces in.

 

Or you can just switch to a S5 gauge cluster and not have to worry about it, like me

 

for those of you who think its a joke drive a whole tank always shifting with the ligh I bet you'll notice much better gas mileage and for those of us who drive our cars alot thats kinda nice

 

2800 is the norm on all of the S4's ive owned, and about 3600-4000 at WOT, i never pay attention to it.

 

My jeep has a shift light on it stock....dumb

 

Thanks alot. If I were to shift when the light comes on I'd be lugging the engine, big time. Where's my electrical tape??? There, fixed.

 

My old 1984 Honda CRX had the light too. I usually got 40+ mpg in that car.

 

I actually think it's cute, in an annoying kinda way. It usually tells me to shift around 3000...

 

Yeah, girls call it "cute".
Guys call it "annoying".

mine comes on at 3k then again aorund 5-6k rpm

 

What shift up light? I own an s4 and i aint got no damn shift up light....not that i want one. But where would this light "flash" from?

 

right by the high beam indicator light

 

crazy I thought that was an s5 thing because I've had to s4 guage clusters and niether of them had the shift up light ??? Strange.....

 

Does it have the highbeam icon right in the center? - All automatics had a cluster without the "shift up" light. Instead, they had the highbeam icon right in the center.
Your car may have it swapped out.
