Manual Transmission
Move the shift lever to N (Neutral) and hold the clutch
pedal to the floor while starting the engine. The vehicle
will not start if the clutch pedal is not all the way down.
Starting Procedure
1. Turn the ignition key to ON/RUN.
Observe the wait to start light. See Wait to Start
Light on page 3 30.
This light may not come on if the engine is hot.
2. As soon as the wait to start light goes off,
immediately turn the ignition key to START. When
the engine starts, let go of the key.
Notice: Holding the key in START for longer than
15 seconds at a time will cause the battery to be
drained much sooner. And the excessive heat can
damage the starter motor.
Notice: If the wait to start indicator stays on after
starting your vehicle, your vehicle may not run
properly. Have your vehicle serviced right away.
3. If the engine does not start after 15 seconds of
cranking, turn the ignition key to LOCK/OFF. Wait
one minute for the starter to cool, then try the
same steps again.
When the engine is cold, let it run for a few minutes
before you move the vehicle. This lets oil pressure build
up. The engine will sound louder when it is cold.
Notice: If you are not in an idling vehicle and the
engine overheats, you would not be there to see the
overheated engine indication. This could damage
the vehicle. Do not let the engine run when you are
not in the vehicle.
Cold Weather Starting
The following tips will help with cold weather starting.
Use the recommended engine oil when the outside
temperature drops below freezing. See Engine Oil on
page 5 16. When the outside temperature drops
below 18°C (0°F), use of the engine coolant heater
is recommended.
See Engine Coolant Heater on page 2 15 for more
information.
See What Fuel to Use in The U.S. on page 5 7 or
What Fuel to Use in Canada and Mexico on page 5 9
for information on what fuel to use in cold weather.
