Use
neutral if you
need to restart a stalled engine, or if
it is necessary to stop briefly with
the engine idling. Shift 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. With
the shift lever in D or S, you
can also use the paddle shifters to
shift the transmission up or down.
Once you begin to use the paddle
shifters in S, the transmission will no
longer upshift or downshift
automatically. For more inf ormation
of driving with the paddle shif ters,
see page .
If 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.
Use this position f or
your normal driving. The transmis-
sion automatically selects a suitable
gear f or your speed and acceleration.
To shift into the S
position, press the release button on
the front of the shift lever, and move
the lever to S. This position is similar
to D, except only gears f rom f irst to
f ourth are selected. The S position
keeps the transmission f rom cycling
between fourth and fifth gears in
stop-and-go driving. 299

The transmission downshif ts to f irst
gear and returns to drive mode (D)
when the vehicle comes to a
complete stop and the vehicle speed
is about 6 mph (10 km/h).
The transmission control system
monitors the accelerator pedal use
and your driving conditions. When
you press the accelerator pedal as in
the normal driving, the system
judges that you are driving at a
constant cruising speed without
using the paddle shif ters. Under
these conditions, D-paddle shif t
mode is canceled, and the
transmission automatically returns to
drive mode(D). If there is a problem in the
transmission while you are driving
with the paddle shifters, the D
indicator f lashes, the D-paddle shif t
mode is canceled, and the
transmission returns to drive mode
(D).
The transmission remains in the
selected gear if you do not accelerate. When the transmission returns to
drive mode (D), the displayed gear
number goes out.
Each time you pull either paddle
shif ter, the transmission shif ts one
gear up or down. If you want to shif t
up or down more than two gears, pull
the paddle shif ter twice, pause, and
then pull it again. The automatic transmission will not
allow you to change shif t if :
You downshif t bef ore the engine
speed reaches the upper limit of
the lower gear.
If you try to do this, the gear
position indicator will f lash the

indicator displays on ‘‘M’’ along with
the selected gear number.
To upshif t, pull the (right) paddle
shif ter. To downshif t, pull the
(lef t) paddle shif ter. When you accelerate f rom a stop,
the transmission starts in f irst gear,
and you must manually upshif t
between f irst and f if th gears. Make
sure you upshif t bef ore the engine
speed reaches the tachometer’s red
zone.
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 are driving in 4th or 5th
gear, the transmission downshifts to
the lower gear under the f ollowing
conditions:
The vehicle slows down to a
certain speed.
You press the brake pedal.
With the shif t lever in S position, you
can select the sequential shif t mode
to shif t gears; much like a manual

the S position, then pull either paddle
shif ter. To cancel the sequential shif t
mode and return to the ordinary
automatic transmission, move the
shif t lever f rom S position. When
moving the shift lever, be careful not
to operate incorrectly. While you are
driving in the sequential shif t mode,
the transmission will not
automatically return to ordinary

Downshifting with the paddle shifter
allows you to increase the engine
braking when going down steep or
long hills, and provides more power
when climbing uphills. You can
upshif t the transmission manually to
reduce the rpm. Driving in the
higher gear helps f uel economy.
The transmission also shif ts
automatically as the vehicle comes to
a complete stop. It downshif ts to f irst
gear when the vehicle speed reaches
6mph(10km/h)orless.

The SH-AWD torque distribution
monitor on the multi-inf ormation
display shows you the amount of
torque being sent to the wheels.
Each wheel: right f ront (RF), lef t
front(LF),rightrear(RR),andleft
rear (LR), has its own torque
indicator.
When you are in sequential shif t
mode, and the vehicle is stopped,
pull the (right) paddle shifter to
shif t to second gear. You will see ‘‘M
2’’ in the display. Starting in second
gear helps to reduce wheelspin in
deep snow or on a slippery surf ace.
The super handling-all wheel drive
(SH-AWD) system is a f ull time all-
wheel-drive system that
automatically controls and transfers
varying amounts of engine torque to
all wheels independently, according
to the driving conditions.
While the SH-AWD system helps to
enhance the vehicle’s driving
stability in all situations, it is still
your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.

Your vehicle still has normal f ront-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible. If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘CHECK SH-AWD SYSTEM’’
message also appears on the multi-
inf ormation display, there is problem
with the SH-AWD system.
If the SH-AWD indicator blinks while
driving, it indicates the dif f erential
temperature is too high. You will also
see an ‘‘SH-AWD DIFF TEMP
HIGH’’ message on the multi-
inf ormation display. If this happens,
pull to the side of the road when it is
saf e, shif t to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked,
Each torque indicator is displayed as
a bar graph divided into 5 segments.
The number of segments represents
the amount of torque distributed to
each wheel.
When there is only a slight change in
torque distribution while driving,
such as cruising on level roads at the
same speed, the torque distribution
monitor may stop displaying the
amount of torque. This is not a
system problem. The monitor will
show the amount if the system
senses any change in torque
distribution.

Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.Make sure the moonroof and the
windows are closed.
If the vehicle is f acing uphill, turn
the front wheels away from the
curb.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb.
Check the indicator on the
instrument panel to verif y that the
security system is set.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.
Turn of f the lights.
Place any packages, valuables, etc.
in the cargo area or take them
with you.
Lock the doors and the tailgate.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.

Your vehicle is equipped with disc
brakes at all four wheels. A power
assist using negative pressure
generated by the engine and the
el ectric vacuum pump helps reduce
the effort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.
All four brakes have audible brake
wear indicato rs.
The
hydraulic system that operates
the brakes has two separate circuits.
Ea ch circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
If the brake pads need replacing, you
will hear a distincti ve, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is norm al for
the brakes to occasionally squeal or
squeak when you apply them.
Resting
your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness.
It also keeps your brake lights on all
the time, confusing drivers behind
you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their effective-
ness. Use the engine to assist the
brakes by taking your foot off the
accelerator and downshifting to a
lower gear.
Check your brakes after driving
th rough deep water. Apply the
brakes moderate ly to see if they feel
norm al. If not, apply them gently and
frequently until they do. Be extra
cautious and alert in your driving.
When
the electric vacuum pump is in
operation, it makes some mechanical
noises come f rom the engine
compartment. This is normal.
When you drive in cold weather or
thinner air at high altitude, the
electric vacuum pump operates more
f requently af ter the engine is started.
For more inf ormation about the
electric vacuum pump, see page . 396
