messages on the multi-inf ormation
display (see pages , and). Without touching the accelerator
pedal, turn the ignition switch to
the START (III) position, then
release the ignition switch. You do
not need to hold the ignition
switch in the START (III) position
to start the engine. Depending on
the outside temperature, the starter motor runs f or about 6 to 9
seconds until the engine starts.
If you hold the ignition switch in
the START (III) position f or more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs f or about 10 to
25 seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds bef ore trying
again.
Make sure the shif t lever is in
Park. Press on the brake pedal. In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery. Apply the parking brake.
Your vehicle’s starting system has an
auto control mode. When you turn
the ignition switch to the START
(III) position, this f eature keeps the
engine’s starter motor running until
the engine starts. Follow these

If this message is on, the ignition
switchhastobeheldinthe
START (III) position manually
until the engine starts. The
ignitionswitchcanbeheldinthat
position up to 15 seconds.
Even though you may be able to
start the engine manually without
the auto control mode of the starting
system, have your dealer inspect
your vehicle.
If there is a problem with the
starting system, you will see a
‘‘CHECK STARTING SYSTEM’’
message on the multi-inf ormation
display when the ignition switch is
turned to the ON (II) position. You
will also see this message when the
auto control mode of the starting
system has a problem.
If the engine does not start within
15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
If the engine fails to start, press
the accelerator pedal all the way
down, and hold it there while
starting to clear flooding. If the
engine still does not start, return
to step 5.

The engine is harder to start in cold
weather. Also, the thinner air f ound at
altitudes above 8,000 f eet (2,400

µ To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can remove the key
from the ignition switch.
Press the brake
pedal and press the release button
on the f ront of the shif t lever to shif t
f rom Park to reverse. To shif t f rom
reverse to neutral, come to a
completestop,andthenshift.Press

into reverse f rom neutral.
Use neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from neutral to
another gear. Use this position f or
your normal driving. The
transmission automatically selects a
suitable gear (1 through 5) f or your
speed and acceleration. You may
notice the transmission shifting up at
higher engine speeds when the
engine is cold. This helps the engine
warm up f aster.
This position mechani-
cally locks the transmission. Use
Park whenever you are turning of f or
starting the engine. To shif t out of
Park, you must press on the brake
pedal and press the release button
on the shif t lever. Make sure your
f oot is of f the accelerator pedal.
If you have done all of the above and
still cannot move the lever out of

With the shif t lever in ‘‘D’’ position,
you can select the Sequential
SportShift mode to shift gears much
like a manual transmission, but
without a clutch pedal.
To enter the Sequential SportShif t
mode, move the shif t lever f urther to
the driver’s side. To return to ‘‘D,’’
move the shift lever to the
passenger’s side.
In Sequential SportShif t mode, each
time you push f orward on the shif t
lever, the transmission shifts to a
higher gear. Pull back on the lever to
downshif t. The number of the gear
selected is displayed on the
instrument panel.
When you move the shif t lever f rom
‘‘D’’ to ‘‘M’’ position, the display
shows the selected gear. The transmission remains in the
selectedgear(5,4,3,2,or1).There
is no automatic downshif t when you
push the accelerator pedal to the
f loor.
When you accelerate away f rom a
stop, the transmission starts in f irst
gear. You have to manually upshift
between f irst and f if th gears. Make
sure you upshif t bef ore the engine
speed reaches the tachometer’s red
zone.

µIf you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
rpm below the red zone.
Bef ore downshif ting, make sure the
engine will not go into the
tachometer’s red zone.
This position is
similar to D, except only the f irst
three gears are selected. Use D
when towing a trailer in hilly terrain,
or to provide engine braking when
going down a steep hill. D can also
keep the transmission f rom cycling
between third, f ourth, and f if th gears
in stop-and-go driving.
ForfasteraccelerationwheninD or
D, you can get the transmission to
automatically downshif t by pushing
the accelerator pedal to the floor.
The transmission will shif t down one,
two, or three gears, depending on
your speed. This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal and pressing the release
button does not work.
Remove the key from the ignition
switch.

When there is only a slight change in
torque distribution while driving,
such as cruising on level roads at the

monitor may stop displaying the
amount of torque. This is not a
