Lincoln Aviator: Starting and Stopping the Engine / Starting a Hybrid Electric Vehicle System
Before starting your vehicle, check the
following:
- Make sure all occupants fasten their
seatbelt.
- Make sure the headlamps and electrical
accessories are off.
- Make sure the parking brake is on.
- Put the transmission in park (P).
Note: Do not touch the accelerator pedal.
- Fully press the brake pedal.
- Press the push button ignition switch.
Note: The green ready indicator illuminates
letting you know that your vehicle is ready
for driving. Since your vehicle comes with a
silent key start, the engine may not start
when your vehicle starts.
When the engine starts for the first time on
your drive, the idle speed increases, this
helps to warm up the engine. If the engine
idle speed does not slow down automatically,
have your vehicle checked by an authorized
dealer.
The system does not function if:
- The passive key frequencies are jammed.
- The key battery has no charge.
If you are unable to start your vehicle, do the
following:

- Open the floor console storage
compartment lid.
- Insert the passive key into the backup
slot.
- With the key in this position, press the
brake pedal then press the push button
ignition switch to switch the ignition on
and start your vehicle.
Guarding Against Exhaust Fumes

in entry of harmful and potentially lethal
fumes into the passenger compartment. If

vehicle, have your vehicle inspected
immediately...
Fast Restart
The fast restart feature allows you to restart
your vehicle within 20 seconds of switching
it off, even if it does not detect a valid
passive key...
