If you need to use the shif t lock
release, it means your vehicle is
developing a problem. Have the
vehicle checked by a dealer.
Push down on the built-in key
while you press the release button
and move the shif t lever out of
Park to neutral.Remove the built-in key from the
shif t lock release slot, then
reinstall the cover. Make sure the

with the paddle shifters.
To shif t up or down, use the
(right) or (lef t) paddle shif ter on
either side of the steering wheel.Each time you pull (right), the
transmission shif ts to a higher gear.
Pull (lef t) to downshif t. You will
see the selected gear number on the
instrument panel.
When you pull either paddle shif ter,
the gear position indicator shows you
the selected gear number.Downshifting with the paddle shifter

´ The transmission control system
monitors the accelerator pedal use
and your driving conditions. When
you press the accelerator pedal as in
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).The automatic transmission will not
allow you to shif t up or down if :
You downshif t bef ore the engine
speed reaches the highest
threshold of the lower gear.
If you try to do this, the gear
position indicator will f lash the
number of the lower gear several
times, then return to a higher gear.
You upshif t bef ore the engine
speed reaches the lowest
threshold of the higher gear.
You pull both paddle shif ters at
thesametime.
You pull one of the two paddle
shifters with another paddle
shif ter being pressed. Each time you pull either paddle
shifter, the transmission shifts one
gear up or down.
The transmission remains in the
selected gear if you do not accelerate. When the transmission returns to
drive mode (D), the displayed gear
number disappears. Hold the paddle shifter for 2
seconds to return to drive mode (D).You can also shift down two gears at
a time if the selected gear is between
the second and sixth, and the engine
speed is within the appropriate range.
Pull the paddle shif ter twice to select
agear.
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.

You upshif t bef ore the engine
speed reaches the lowest
threshold of the higher gear. 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. 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. When you are driving, 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.
The vehicle detects that you are
driving uphill or downhill. 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 shif ts f rom f irst to second
automatically. You must manually
upshif t between second and sixth
gears. Make sure you upshif t bef ore
the engine speed reaches the
tachometer’s red zone.
The transmission remains in the
selectedgear(6,5,4,3,or2).There
is no automatic downshif t when you
push the accelerator pedal to the

´Drive in the highest gear that lets
the engine run and accelerate
smoothly. This will give you good
f uel economy and ef f ective
emissions control. The f ollowing
shif t points are recommended: 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
‘‘M2’’ in the display. Starting in
second gear helps to reduce
wheelspin in deep snow or on a
slippery surf ace. You pull both paddle shif ters at
thesametime.
You pull one of the two paddle
shifters with another paddle
shif ter being pressed.

µ The super handling-all wheel drive
(SH-AWD) system is a f ull time all-
wheel-drive system that
automatically controls and transf ers
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.
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.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.

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.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 a
problem with the SH-AWD system.
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.

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The brake pedal
assist f unction increases the f orce
you apply to the brake pedal during
an emergency stop. When the brake
pedal assist is activated, the e-
pretensioners (if equipped) tighten
f ront seat belts (see page ). The
anti-lock brake system (ABS) helps
you retain steering control when
braking very hard (see page ).
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, reduces their ef f ectiveness and
reduces brake pad lif e. In addition,
f uel economy can be reduced. It also
keeps your brake lights on all the
time, conf using drivers behind you.The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels. Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.If the brake pads need replacing, you
will hear a distinctive, 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 normal f or
the brakes to occasionally squeal or
squeak when you apply them. 24
