Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake, or slow, the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer (STS Only) on page 4-40for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
Ignition Positions
Your vehicle has an
electronic keyless ignition
with pushbutton start.
/(START):Press this button while your foot is on the
brake to start the engine. The shifter must be in PARK (P)
or NEUTRAL (N) to start the engine and the keyless
access transmitter must be in the vehicle for the ignition
to work.
2-24

9ACC (OFF/ACCESSORY):When this button is
pressed, the engine will turn off even if the shifter is not in
PARK (P). If the shifter is in PARK (P), the ignition mode
will change to RAP, if all doors are closed. The ignition
mode will change to OFF, if a front door is opened. See
Retained Accessory Power (RAP) on page 2-25for more
information. If the shifter is not in PARK (P), the ignition
mode will change to ACC. SeeShifting Into Park (P) on
page 2-36.
When the engine is off, press this button to place the
vehicle in accessory mode. ACCESSORY ACTIVE will
display on the Driver Information Center (DIC). This mode
allows you to use things like the radio and the windshield
wipers while the engine is off. Use accessory mode if you
must have your vehicle in motion while the engine is off,
for example, if your vehicle is being towed. If the door is
open while in accessory mode, the key in reminder chime
will sound continuously.
If the push-button start is not working, your vehicle
may be near a strong radio antenna signal causing
interference to the keyless access system. SeeDIC
Warnings and Messages on page 3-79for more
information.
After being in ACC for about 20 minutes, the vehicle will
automatically enter RAP or will turn off, depending on if
the doors are opened or closed.Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 20 minutes after the engine is turned off:

When the engine begins cranking, let go of the
button. The idle speed will go down as your
engine gets warm.
If the battery in the keyless access transmitter is
weak, the DIC will display FOB BATTERY LOW.
You can still drive the vehicle. See “Battery
Replacement” underKeyless Access System
Operation on page 2-5for more information.
Notice:Holding the button in for longer than
15 seconds at a time will cause the vehicle’s battery
to be drained much sooner. This can also cause
damage to the starter motor. Wait 15 seconds
between each try to avoid draining your vehicle’s
battery or damaging the starter.
2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.Notice:Your engine is designed to work with the
electronics in your 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, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
In very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also have an
internal thermostat in the plug end of the cord. This will
prevent operation of the engine coolant heater when
the temperature is at or above 0°F (−18°C) as noted
on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
For the 3.6L V6 engine, the cord is located in
the engine compartment on the passenger’s side of
the vehicle in front of the fuse block.
For the 4.6L V8 engine, the cord is located in the
engine compartment on the driver’s side of the
vehicle near the inner fender and above the strut.
For the 4.4L V8 engine, the cord is located in
the front of the engine compartment, on the
passenger’s side of the vehicle. The plug will be
inside the upper grille cutout.3. You must remove the plastic cap to access
the plug.
4. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
5. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away from
moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature,
the kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Automatic Transmission Operation
(5-Speed Automatic)
The shift lever is located on the center console between
the front seats.
There are several different
positions for the shift lever.
PARK (P):This position locks the rear wheels. It is the
best position to use when you start the engine because
your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
SeeShifting Into Park (P) on page 2-36.If
you are pulling a trailer, seeTowing a Trailer
(STS Only) on page 4-40.
