Starting and Stopping the Engine
STARTING AND STOPPING THE
ENGINE – FREQUENTLY ASKED
QUESTIONS
Why is the engine idle speed high when
I am starting the engine?
The speed at which the engine idles
immediately after starting is optimized
to minimize vehicle emissions and
maximize cabin comfort and fuel
economy.
Why does the engine not crank?
You can only attempt to start the
engine for a limited amount of time
before the starting system temporarily
disables. If you exceed the starting
time limit, a message may appear and
you cannot attempt to start the engine
for at least 15 minutes.
Why do I experience different driving
characteristics?
If you disconnect the battery, your
vehicle may exhibit some unusual
driving characteristics for about 5 mi
(8 km) after you reconnect it. This is
because the engine management
system must realign itself with the
engine. You can disregard any unusual
driving characteristics during this
period.
Why can I not start the engine?
If you cannot start the engine after
three attempts, wait 10 seconds and
do the following:
1.
Fully press the brake pedal or the
clutch pedal.
Note: Make sure that the parking brake is
applied.
Note: Make sure that the transmission is in
park (P) or neutral (N).
2. Fully press the accelerator pedal and
hold it there.
3. Press the push button ignition switch.

Why does the system not detect a
passive key?
If the system does not detect a passive
key and you are unable to start the
engine, insert the passive key into the
backup position and press the push
button ignition switch to start the
engine. See Accessing the Passive
Key Backup Position (page 156).
