A vehicle includes a fuel tank, a jet pump and a controller. The fuel tank has a passive side and an active side. Each of the sides includes a fuel level indicator. The jet pump is disposed within the active side and is configured to maintain a fuel level above a first threshold, based on each of the indicators, on the active side by siphoning fuel from the passive side during operation in a combustion mode. The controller is configured to, in response a battery charge level being below a second threshold during operation in an electric mode and a detected hill climb via a route guidance system, activate the jet pump to siphon fuel such that a fuel level within the active side rises above the first threshold.

1. A vehicle comprising: a fuel tank having a passive side and an active side, each of the sides including a fuel level indicator;a jet pump disposed within the active side and being configured to maintain a fuel level above a first threshold, based on each of the indicators, on the active side by siphoning fuel from the passive side during operation in a combustion mode; anda controller configured to, in response a battery charge level being below a second threshold during operation in an electric mode and a detected hill climb via a route guidance system, activate the jet pump to siphon fuel such that a fuel level within the active side rises above the first threshold. 2. The vehicle of claim 1 further comprising a fuel pump connected with the jet pump, and being configured to activate the jet pump to provide fuel to an engine. 3. The vehicle of claim 1, wherein the controller is further configured to, in response to the fuel level being less than the first threshold, initiate a maneuver such that fuel is transferred from the passive side to the active side. 4. The vehicle of claim 1, wherein the controller is further configured to, in response to the detected hill climb and an availability of an alternate route having a maneuver to transfer fuel from the active side to the passive side, operate the route guidance system to select the alternate route. 5. The vehicle of claim 4, wherein the controller is further configured to, in response to the availability of the alternate route, compare an estimated fuel transfer amount to the first and second thresholds before selecting the alternate route. 6. The vehicle of claim 5, wherein the controller is further configured to, in response to the estimated fuel transfer amount in addition to the fuel level being less than the first threshold, abort selecting the alternate route. 7. The vehicle of claim 5, wherein the controller is further configured to, in response to the estimated fuel transfer amount in addition to the fuel level being less than the first threshold and the battery charge being less than the second threshold, abort selecting the alternate route. 8. A vehicle control method comprising: in response to detecting a hill climb via a guidance system during operation in an electric mode when a charge level of a battery is below a second threshold and a fuel level in an active side of a fuel tank is below a first threshold, activating a fuel pump to draw fuel from a passive side of the fuel tank to raise the fuel level above the first threshold. 9. The vehicle control method of claim 8 further comprising in response to the detecting and an availability of an alternate route having a maneuver to transfer fuel from the active side to the passive side, operating the guidance system to select the alternate route. 10. The vehicle control method of claim 9 further comprising in response to the availability of the alternate route, comparing an estimated fuel transfer amount to the first and second thresholds before selecting the alternate route. 11. The vehicle control method of claim 10 further comprising in response to the comparing and the first and second thresholds being greater than the first threshold, initiating the maneuver. 12. The vehicle control method of claim 10, wherein the comparing further includes detecting if the estimated fuel transfer amount in addition to the fuel level and battery charge provides sufficient power to drive the vehicle during the hill climb.
