9-24 Driving and Operating
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for
a few seconds or until the
vehicle starts. If the engine does
not start and the key is held in
START for many seconds,
cranking will be stopped after
15 seconds to prevent cranking
motor damage. To prevent gear
damage, this system also
prevents cranking if the engine
is already running. Engine
cranking can be stopped by
turning the ignition switch to
ACC/ACCESSORY or
LOCK/OFF.Notice:
Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after
five to 10 seconds, especially in
very cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Push the
accelerator pedal all the way to
the floor and hold it there as you
hold the key in START for a
maximum of 15 seconds. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool. When the engine starts,
let go of the key and accelerator. If the vehicle starts briefly but
then stops again, repeat the
procedure. This clears the extra
gasoline from the engine. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
until the oil warms up and
lubricates all moving parts.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical parts
or accessories, 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.

Transfer Case
When to Check and Change
Lubricant
Refer to the Maintenance Schedule
to determine how often to check the
lubricant and when to change it.
See
Maintenance Schedule on
page 11‑3. How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
If the level is below the bottom of
the fill plug hole, located on the
transfer case, the vehicle will need
some lubricant added. Add enough
lubricant to raise the level to the
bottom of the fill plug hole. A fluid
loss could indicate a problem; check
and have it repaired, if needed.
