If Engine Fails To Start
WARNING!
• Never pour fuel or other flammable liquid
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in flash fire causing serious personal
injury.
• Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine
has started, ignite and damage the con-
verter and vehicle.
• If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery
in another vehicle. This type of start can be
dangerous if done improperly. Refer to
"Jump Starting" in "What To Do In Emer-
gencies" for further information.
Clearing A Flooded Engine (Using ENGINE
START/STOP Button)
If the engine fails to start after you have followed
the "Normal Starting" or "Extreme Cold
Weather" procedures, it may be flooded. To
clear any excess fuel:
1. Press and hold the brake pedal.
2. Press the accelerator pedal all the way to the
floor and hold it.
3. Push and release the ENGINE START/
STOP button once.
The starter motor will engage automatically, run
for 10 seconds, and then disengage. Once this
occurs, release the accelerator pedal and the
brake pedal, wait 10 to 15 seconds, then repeat
the "Normal Starting" procedure.
