9-18 Driving and Operating
Manual Transmission
The shift lever should be in Neutral
and the parking brake engaged.
Hold the clutch pedal to the floor
and start the engine. The vehicle
will not start if the clutch pedal is not
all the way down.
Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition to START.
When the engine cranks, let go
of the key. The idle speed will go
down as the engine gets warm.
The vehicle has a
Computer Controlled Cranking
System. It assists in starting
the engine and protects
components. If the ignition key
is turned to START and then
released when the engine
begins cranking, the engine
will continue cranking for a
few seconds or until the engine
starts. If the engine does not
start and the key is held in
START, cranking will be stopped
after 15 seconds to prevent
damage. To prevent gear
damage, cranking is not allowed
if the engine is running. Engine
cranking can be stopped by
turning the ignition key to ACC/
ACCESSORY or LOCK/OFF.
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. Wait about
15 seconds between each try to
help avoid draining the battery or
damaging the starter.
2. If the engine does not start, wait
about 15 seconds and try again.
Wait about 15 seconds between
each try.
When the engine has run about
10 seconds to warm up, the
vehicle is ready to be driven. Do
not run the engine at high speed
when it is cold.
If the weather is below freezing
(0°C or 32°F), let the engine run
for a few minutes to warm up.
3. If the engine still will not start,
or starts but then stops, it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you hold the key in START for
about three seconds. If the
vehicle starts briefly but then
stops again, do the same thing,
but this time keep the pedal
down for five or six seconds.
This clears the extra gasoline
from the engine.
Notice: The engine is designed to
work with the electronics in the
vehicle. If electrical parts or
accessories are added, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.
