It does throw you off a bit. Yes, the shifter slides right into 4th gear. You'll know it because the car makes a deep rumbling sound, rpm drops, and it's slow to accelerate. If you're driving in this ultra fuel saving mode then it doesn't matter because you're not trying to accelerate fast anyway.
At first I thought I missed 2nd but as I got accustomed to driving this car, it became more obvious that the car was making the decision. Under normal or aggressive driving you'll never see this happen
