STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 10-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!• When leaving the vehicle, always make sure the
keyless ignition node is in the OFF mode, remove
the key fob from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be (Continued) WARNING! (Continued)warned not to touch the parking brake, brake pedal
or the gear selector.
• Do not leave the Key Fob in or near the vehicle, or
in a location accessible to children, and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ACC or ON/RUN mode.
A child could operate power windows, other con-
trols, or move the vehicle.
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Cycle the ignition to the START position and
release when the engine starts. If the engine fails to start402 STARTING AND OPERATING
Page 405 of 675

within 10 seconds, cycle the ignition to the OFF position,
wait five seconds, then repeat the “Normal Starting”
procedure.
Automatic Transmission
Start the engine with the gear selector in the NEUTRAL
or PARK. Apply the brake before shifting into any
driving range.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
pressed to shift out of PARK.
Tip Start Feature
Do not press the accelerator. Cycle the ignition switch
briefly to the START position and release it. The starter
motor will continue to run but will automatically disen-
gage when the engine is running. Extreme Cold Weather (Below –20°F or 29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while the engine is cranking. This should clear any
excess fuel in case the engine is flooded.
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. 5STARTING AND OPERATING 403

CAUTION! (Continued)• Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
WARNING!• It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when (Continued) WARNING! (Continued)the engine is idling normally and your foot is
firmly pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always shift an
automatic transmission into PARK, or a manual
transmission into FIRST gear or REVERSE, turn
the engine OFF, apply the parking brake, and
remove the ignition key. When the ignition is in the
LOCK/OFF (key removal) position, an automatic
transmission is locked in PARK, securing the ve-
hicle against unwanted movement.
• When leaving the vehicle, always remove the key
fob from the ignition and lock your vehicle. If
equipped with Keyless Enter-N-Go, always make (Continued)406 STARTING AND OPERATING

WARNING! (Continued)sure the keyless ignition node is in “OFF” mode,
remove the Key Fob from the vehicle and lock the
vehicle.
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission
is in PARK before leaving the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be (Continued) WARNING! (Continued)seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the gear selector.
• Do not leave the key fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ACC or ON/RUN mode.
A child could operate power windows, other con-
trols, or move the vehicle.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/
OFF (key removal) position. The Key Fob can only be
