GMC Terrain: Fuel / Filling the Tank (Gasoline)
Warning
Fuel vapors and fuel fires burn violently and can cause injury or death.
- To help avoid injuries to you and others, read and follow all the instructions on the fuel pump island.
- Turn off the engine when refueling.
- Keep sparks, flames, and smoking materials away from fuel.
- Do not leave the fuel pump unattended.
- Avoid using electronic devices while refueling.
- Do not reenter the vehicle while pumping fuel.
- Keep children away from the fuel pump and never let children pump fuel.
- Fuel can spray out if the refueling nozzle is inserted too quickly. This spray can happen if the tank is nearly full, and is more likely in hot weather. Insert the refueling nozzle slowly and wait for any hiss noise to stop prior to beginning to flow fuel.
To open the fuel door, push and release the rearward center edge of the door.
The vehicle has a capless fuel system and does not have a fuel cap. The filling nozzle must be fully inserted and latched prior to starting fuel flow.
Warning
Overfilling the fuel tank by more than three clicks of a standard fill nozzle may cause:
- Vehicle performance issues, including engine stalling and damage to the fuel system.
- Fuel spills.
- Potential fuel fires.
Be careful not to spill fuel. Wait a few seconds after you have finished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Exterior Care.
Warning
If a fire starts while you are refueling, do not remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately.
Filling the Tank with a Portable Gas Can
If the vehicle runs out of fuel and must be filled from a portable gas can:
- Locate the capless funnel adapter from under the spare tire.
- Insert and latch the funnel into
the capless fuel system.
Warning
Attempting to refuel without using the funnel adapter may cause fuel spillage and damage the capless fuel system. This could cause a fire and you or others could be badly burned and the vehicle could be damaged.
- Remove and clean the funnel adapter and return it to the storage location.
Fuel Filter Replacement (Diesel)
Warning
Diesel fuel is flammable. It could
start a fire if something ignites it,
and people could be burned. Do
not let it get on hot engine parts,
