STARTING AND OPERATING59
3. If the engine fails to start within ten
seconds, place the ignition in the STOP
(OFF/LOCK) position, wait five seconds to
allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at
least 10 minutes, then repeat the
procedure.
If Engine Fails To Start
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme Cold
Weather” procedure, and has not experienced
an extended park condition as identified in
“Extended Park Starting” procedure, it may be
flooded. Push the accelerator pedal all the way
to the floor and hold it there. Crank the engine
for no more than 15 seconds. This should clear
any excess fuel in case the engine is flooded. Leave the ignition key in the MAR (ON/RUN)
position, release the accelerator pedal and
repeat the “Normal Starting” procedure.
After Starting
The idle speed is controlled automatically, and
it will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine and
permits quicker starts in cold weather.
Connect the cord to a 110-115 Volt AC electrical
outlet with a grounded, three-wire extension
cord.
For ambient temperatures below 0°F (-18°C),
the engine block heater is recommended. For
ambient temperatures below -20°F (-29°C),
the engine block heater is required.
The engine block heater cord is routed under
the hood, behind to the driver’s side headlamp.
Follow the steps below to properly use the
engine block heater:
CAUTION!
To prevent damage to the starter, do not
crank continuously for more than 10 seconds
at a time. Wait 10 to 15 seconds before trying
again.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in flash fire causing serious personal
injury.
Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter
and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly
Úpage 204.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds
before trying again.

Towing Tips
Before towing, practice turning, stopping, and
backing up the trailer in an area located away
from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, use the Electronic Range Select (ERS)
shift control to select a lower gear range.
NOTE:
Using a lower gear range while operating the
vehicle under heavy loading conditions will
improve performance and extend transmission
life by reducing excessive shifting and heat
build up. This action will also provide better
engine braking.
Electronic Range Select (ERS)
When using the ERS shift control, select the
highest gear that allows for adequate perfor -
mance and avoids frequent downshifts. For
example, choose “5” if the desired speed can
be maintained. Choose “4” or “3” if needed
to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear range or vehicle speed when
grade and road conditions allow.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Cruise Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Cruise Control in flat terrain and with
light loads to maximize fuel efficiency.

SAFETY161
Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect you
in a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
AVV/START or MAR/ACC/ON/RUN position. If
the ignition switch is in the STOP/OFF/LOCK
position the air bag system is not on and the air
bags will not inflate. The ORC contains a backup power supply
system that may deploy the air bag system even
if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in
the instrument panel for approximately four to
eight seconds for a self-check when the ignition
switch is in the MAR/ACC/ON/RUN position.
After the self-check, the Air Bag Warning Light
will turn off. If the ORC detects a malfunction in
any part of the system, it turns on the Air Bag
Warning Light, either momentarily or
continuously. A single chime will sound to alert
you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While the
air bag system is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.
Failure to replace the seat belt assembly
could increase the risk of injury in colli
-
sions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the
seat belt or children who are using booster
seats. The locked mode is only used to
install rear-facing or forward-facing child
restraints that have a harness for
restraining the child.
