DRIVE (D):This position is for normal driving with
the automatic transmission. It provides the best
fuel economy for your vehicle. If you need more
power for passing, and you are:
Going less than about 35 mph (55 km/h),
push your accelerator pedal about halfway down.
Going about 35 mph (55 km/h), push your
accelerator all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-13.
INTERMEDIATE (I):This position is also used for
normal driving. However, it reduces vehicle speed without
using your brakes for slight downgrades where the
vehicle would otherwise accelerate due to steepness
of grade. If constant upshifting or downshifting occurs
while driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
INTERMEDIATE (I) instead of DRIVE (D) when driving
on hilly, winding roads and when towing a trailer, so that
there is less shifting between gears.
LOW (L):This position reduces vehicle speed more
than INTERMEDIATE (I) without actually using
your brakes. You can use it 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 LOW (L) until the
vehicle is going slowly enough.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.Transmission Overheating
If the transmission uid temperature rises above 284°F
(140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. SeeEngine
Coolant Temperature Warning Light on page 3-33for
more information. When the transmission overheats
it will go into a protection mode and will default shift into
fth gear if in the DRIVE (D) position, or second gear
if in the LOW (L) position. 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, see
Engine Overheating on page 5-24.
2-26

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 3-34.
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 3-33for
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, see
Engine Overheating on page 5-24.

SECOND (2) and THIRD (3) Gear
Start Feature
When accelerating your vehicle from a stop in snowy
and icy conditions, you may want to select SECOND (2)
and 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 Manual Shift Mode, the vehicle can accelerate
from a stop in SECOND (2) or THIRD (3).
1. Move the shift lever from DRIVE (D) into the
manual gate.
2. With the vehicle stopped, move the shift lever
forward to select SECOND (2) or THIRD (3).
The vehicle will start from a stop position in
SECOND (2) or THIRD (3).
3. Once the vehicle is moving select the desired
drive gear or move the shift lever to the
DRIVE (D) position.
Parking Brake
The parking brake lever is located to the right of the
driver’s seat.
To set the parking brake, hold the brake pedal down
and pull up on the parking brake lever. If the ignition is
on, the brake system warning light will come on.
2-31

To release the parking brake, hold the brake pedal
down. Pull the parking brake lever up until you can
press the release button. Hold the release button in
as you move the brake lever all the way down.
Make sure to release the parking brake before driving
the vehicle.
If the parking brake is applied and the vehicle is
moving at least 4 mph (6 km/h), a chime will activate
to remind you to release the parking brake.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make
sure that the parking brake is fully released and
the brake warning light is off before driving.Shifting Into PARK (P)
{CAUTION:
It can be 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.
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, use
the steps that follow. If you are pulling a trailer,
seeTowing a Trailer on page 4-33.
1. Hold the brake pedal down with your foot and set
the parking brake. SeeParking Brake on page 2-31
for more information.
2. Move the shift lever into PARK (P) by pressing the
button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
