Section 2 Features and Controls
2-1
Automatic Transmission Operation
(3.6L V6 with 6-Speed)
The shift lever for the automatic transmission is located
on the console between the seats.
Maximum engine speed is limited when the vehicle is in
PARK (P) or NEUTRAL (N) to protect driveline
components from improper operation.
There are several different positions for the shift lever.
When using the Manual Shift Mode (MSM), a number
indicating the gear selected will appear on the
instrument cluster below the shift position display. For
more information on the manual shift option see “Manual
Shift Mode” in this section.PARK (P):This position locks the front wheels. It is the
best position to use when the engine is started
because the 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 2-33. If you are pulling a trailer, see
Towing a Trailer on page 4-32.
Make sure the shift lever is fully in PARK (P) before
starting the engine. The vehicle has an automatic
transmission shift lock control system.
2-28
DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If the
vehicle needs more power for passing, and it is:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator pedal all the way down.
The vehicle will shift down to the next gear and
have more power.
Downshifting the transmission in slippery road conditions
could result in skidding, see Skidding underLoss of
Control on page 4-12.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
MANUAL SHIFT MODE (M):This position, available on
the models with the Manual Shift Mode (MSM), allows
you to change gears similar to a manual transmission.
If your vehicle has this feature, see “Manual Shift
Mode (MSM)”.
Manual Shift Mode (MSM) (Automatic
Transmission)
To use this feature, do the following:
1. Move the shift lever from DRIVE (D) to the left into
the manual gate.
While driving in manual shift mode, the transmission
will remain in the driver gear selected. When
coming to a stop in the manual position, the vehicle
will automatically shift to FIRST (1) gear.
2-30
2. Push the shift lever forward toward the plus (+) to
upshift or rearward toward the minus (−)to
downshift.
When using the Manual Shift Mode (MSM) the
number of the gear selected will appear on
the instrument cluster below the shift position
display.
In manual shift mode all six forward gears can be
selected.
While using the MSM feature the vehicle will have
operation similar to a manual transmission. You can use
this for sport driving or when driving hilly roads to
stay in gear longer or to downshift for more power or
engine braking.
The transmission will only allow you to shift into gears
appropriate for the vehicle speed:
The transmission will not automatically shift to the
next higher gear without moving the shift lever.
The transmission will not allow shifting to the next
lower gear if the vehicle speed is too high.
If the vehicle does not respond to a gear change, or
detects a problem with the transmission, the range
of gears may be reduced and the Malfunction Indicator
Lamp will come on. SeeMalfunction Indicator Lamp
on page 3-36.
Transmission Overheating
If the transmission uid temperature rises above
270°F (132°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-35for
more information. When the transmission overheats
it will go into a protection mode and will default into a
different shift sequence to help cool the transmission
uid. This shift sequence is the same for both DRIVE (D)
position and manual mode. Continue driving the
vehicle in either position depending on the required
vehicle speed and load. Once the uid temperature
lowers to the normal temperature range, the
transmission will return to the normal shift patterns.
Towing or driving on long hills can cause the
transmission uid temperature to be higher than normal.
If the transmission uid temperature will not cool, you
may need to pull over and check the transmission
uid level. You should also check the engine coolant
temperature. If it is hot, seeEngine Overheating
on page 5-25.
2-31
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you do the following:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you are
pulling a trailer. See the Maintenance Schedule for
more on this. Things that are especially important in
trailer operation are automatic transmission uid, engine
oil, belts, cooling system and brake system. Each of
these is covered in this manual, and the Index will help
you nd them quickly. If you are trailering, it is a
good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode or
ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly, some
or all of these things can hurt you.
Notice:Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
