154 GETTING TO KNOW YOUR INSTRUMENT PANEL

After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
If Engine Fails To Start
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 trans-
mission 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. Refer to
“Jump-Starting Procedures” in “In Case Of Emer-
gency” for further information.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce fuel con-
sumption. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or pressing the accelerator pedal
will automatically re-start the engine.
Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. At that time, the
system will go into STOP/START READY and if
all other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following Must Occur:
• The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster display within the Stop/Start section.
Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.

seated against the wheel.
JUMP-STARTING
If your vehicle has a discharged battery, it can be jump-
started using a set of jumper cables and a battery in another
vehicle or by using a portable battery booster pack. Jump-
starting can be dangerous if done improperly so please
follow the procedures in this section carefully.
WARNING!
Do not attempt jump-starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than
12 Volts or damage to the battery, starter motor, alter-
nator or electrical system may occur.
NOTE: When using a portable battery booster pack, follow
the manufacturer’s operating instructions and precautions.
Preparations For Jump-Start
The battery in your vehicle is located under the passenger’s
front seat. There are remote locations located under the
hood to assist in jump-starting.
Remote Battery Posts
1 — Remote Positive (+)Post (covered with protective cap)
2 — Remote Negative (-)Post

IN CASE OF EMERGENCY 425

WARNING!
•Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
NOTE: Be sure that the disconnected ends of the cables do
not touch while still connected to the either vehicle.
1. Set the parking brake, shift the automatic transmission into PARK and turn the ignition to OFF/LOCK.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
3. Remove the protective cover over the remote positive (+) battery post. Pull upward on the cover to remove it. 4. If using another vehicle to jump-start the battery, park
the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this could
establish a ground connection and personal injury
could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could
result in personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
NOTE: Make sure at all times that unused ends of jumper
cables are not contacting each other or either vehicle while
making connections.
426 IN CASE OF EMERGENCY

Connecting The Jumper Cables
1. Connect the positive(+)end of the jumper cable to the
remote positive (+)post of the discharged vehicle.
2. Connect the opposite end of the positive (+)jumper
cable to the positive (+)post of the booster battery.
3. Connect the negative end (-)of the jumper cable to the
negative (-)post of the booster battery.
4. Connect the opposite end of the negative (-)jumper
cable to the remote negative (-)post of the vehicle with
the discharged battery.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury. Only use the specific ground point, do
not use any other exposed metal parts.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
CAUTION!
Do not run the booster vehicle engine above 2000 rpm
since it provides no charging benefit, wastes fuel and
can damage booster vehicle engine.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable from
the remote negative (-)post of the discharged vehicle.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery.
3. Disconnect the positive (+)end of the jumper cable from
the positive (+)post of the booster battery.
4. Disconnect the opposite end of the positive (+)jumper
cable from the remote positive (+)post of the discharged
vehicle.
5. Reinstall the protective cover over the remote positive (+) post of the discharged vehicle.
7
IN CASE OF EMERGENCY 427

If frequent jump-starting is required to start your vehicle
you should have the battery and charging system tested at
your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if plugged
in long enough without engine operation, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
REFUELING IN EMERGENCY
The funnel for the Cap-Less Fuel System is located in the
spare tire storage area. If your vehicle is out of fuel and an
auxiliary fuel can is needed, insert the funnel into the filler
neck and proceed to fill the vehicle.
For more information on the Cap-Less Fuel System refer to
“Refueling The Vehicle” in “Starting And Operating ” in
this manual.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
•On the highways — slow down.
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
