SYSTEM DESCRIPTION
The fuel pump control module (FPCM) controls the discharging volume of the fuel pump by the FPCM control signals (Low/Mid/High) depending on driving conditions.
| Conditions | Amount of fuel flow | Supplied voltage |
|---|---|---|
| For 1 second after turning ignition switch ON | Low | Approximately 8.5 V |
|
High | Battery voltage 12 V |
| Except the above | Mid | Approximately 10 V |

LATCH (Lower Anchors and Tethers for CHildren) system
LATCH system lower anchor locations - bench seat
Your vehicle is equipped with special anchor points that are used with LATCH system compatible child restraints. This system may also be referred to as the ISOFIX or ISOFIX compatible system. With this system, you do not have to use a vehicle seat belt to secure the child restraint unless the combined weight of the child and child restraint exceeds 65 lbs. (29.5 kg). If the combined weight of the child and child restraint is greater than 65 lbs. (29.5 kg), use the vehicle’s seat belt (not the lower anchors) to install the child restraint. Be sure to follow the child restraint manufacturer’s instructions for installation.
