2-11

Ignition Positions
With the key in the ignition
switch, you can turn it to
four different positions.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.
9(LOCK/OFF):This is the only position from
which you can remove the key. The shift lever must be
in PARK (P) with the ignition in LOCK/OFF to remove
the key.ACC (ACC/ACCESSORY):This position unlocks the
transmission. It also lets you use things like the
radio and windshield wipers while the engine is not
running. To use ACC/ACCESSORY, turn the key
clockwise to the rst position. Use this position if your
vehicle must be pushed or towed. SeeRecreational
Vehicle Towing on page 4-26.
Never try to push-start your vehicle.
R(ON/RUN):This position is where the key returns to
after you start the engine and release the key. The
ignition switch will stay in this position while the engine
is running. But even while the engine is not running,
you can use ON/RUN to operate your electrical
accessories and to display some instrument panel
warning lights. Use the ON/RUN position for
push-starting a vehicle with a manual transmission.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start your vehicle if
the battery is allowed to drain for an extended period
of time.
/(START):This position starts the engine. When the
engine starts, release the key. The ignition switch
will return to the ON/RUN position for normal driving.
2-22

THIRD (3):This position, available on the SE model, is
also used for normal driving. However, it reduces
vehicle speed more than DRIVE (D) without using your
brakes. Here are some times you might choose
THIRD (3) instead of DRIVE (D):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
LOW (L):This position, available on the SE model,
reduces vehicle speed more than THIRD (3) without
using your brakes. You can use LOW (L) on hills. It can
help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
You can use LOW (L) on very steep hills, or in deep
snow or mud. If the shift lever is put in LOW (L),
the transmission will not shift into rst gear until the
vehicle is going slowly enough.
Notice:Driving in LOW (L) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
LOW (L) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or DRIVE (D)
instead of LOW (L).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 MODE (M):This position, available on the
GT/GXP models, allows you to change gears similar to a
manual transmission. If your vehicle has this feature,
see Manual Shift Mode (MSM) following.
Manual Shift Mode (MSM) (Automatic
Transmission)
To use this feature, do the following:
1. Move the shift lever from DRIVE (D) rearward and
then to the right into the MANUAL MODE (M).
While driving in manual shift mode, the transmission
will remain in the driver gear selected.
2. Press the shift level forward to upshift or rearward
to downshift.
The odometer display on the instrument panel cluster
will change from the vehicle’s mileage to the letter M, for
manual shift mode, and a number indicating the
requested gear range when moving the shift lever
forward or rearward. SeeSpeedometer and Odometer
on page 3-29for more information.
2-29

While using the MSM feature the vehicle will have rmer
shifting and sportier performance. You can use this
for sport driving or when climbing hills 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 and engine revolutions
per minute (RPM):
The transmission will not automatically shift to the
next higher gear if the engine RPM is too high.
The transmission will not allow shifting to the next
lower gear if the engine RPM 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 3-38for more information.
SECOND (2)/THIRD (3) Gear Start
Feature
Notice:If you attempt a third gear start while
trailering or towing a heavy load, you will notice
reduced engine power. This could overheat
and damage your transmission. Do not attempt a
third gear start while trailering or towing your
vehicle.
If your vehicle has the 6-speed transmission, when
accelerating your vehicle from a stop in snowy and icy
conditions, you may want to shift into SECOND (2),
or THIRD (3) gear. A higher gear, and light application
of the gas pedal, may allow you to gain more traction
on slippery surfaces.
With the MSM, the vehicle can accelerate from a stop in
SECOND (2) or THIRD (3).
1. Move the shift lever from DRIVE (D) into the
MANUAL MODE (M) position.
2. With the vehicle stopped, move the lever forward
towards the plus (+) to select SECOND (2) or
THIRD (3)gear. The vehicle will start from a stop
position in SECOND (2) or THIRD (3) gear.
3. Once the vehicle is moving select the desired
drive gear.

Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
When in manual shift mode, the odometer will change
from the vehicle’s mileage to the letter M, for manual
mode, and a number indicating the requested gear
range when moving the shift lever forward or rearward.
For more information seeAutomatic Transmission
Operation on page 2-27.
Your vehicle has a tamper resistant odometer.
Repair or replacement of your instrument panel cluster
should only be performed by your dealer/retailer.
Trip Odometer
The trip odometer can display how far you have driven
since you last reset it.
For more information seeDIC Operation and Displays
on page 3-43.
Tachometer
The tachometer
shows your engine
speed in revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.2.4L and 3.6L Engine

Driving On Grades
When towing a trailer on long uphill grades and the
outside temperature is above 85°F (29°C), reduce your
vehicle speed to 45 mph (72 km/h) to avoid overheating
the engine cooling system.
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) for an automatic transmission or into
gear for a manual transmission. When parking
uphill, turn your wheels away from the curb. When
parking downhill, turn your wheels into the curb.
2. Have someone place chocks under the trailer
wheels.
3. When the chocks are in place, release the regular
brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and shift into PARK (P).
5. Release the regular brakes.
4-33

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine,
shift into a gear, and
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 (do not
overll), engine oil, drive belt, 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 this information
before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-33.
