Your vehicle may be due for service. We can offer you the following:

* TIRE ROTATION (for Model Years 2015 & Older)

Your vehicle is equipped with an Engine Oil Life System (OLS). When the "Change Engine Oil Soon" message appears in the Driver Information Center, you should schedule an appointment and come in.

I got those for my LEAF too. At least they didn't offer to drain and refill the electrons in the HV battery...

Got many of these with my Leafs. My first dealer was good and traded a free oil change coupon for a free tire rotation.
