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.
When you are driving in D position,
pulling the either paddle shif ter
switches f rom the ordinary
automatic transmission [drive mode
(D)] to the D-paddle shif t mode. You
can shif t the transmission up or
down manually with the paddle
shif ters.
To shif t up or down, use the
(right) or (lef t) paddle shif ter on
each side of the steering wheel.
Downshif ting gives you more power
when climbing, and provides engine
braking when going down a steep hill.

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

paddle shif ter, the gear position
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

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

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. 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.

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 f our wheels. A power
assist using negative pressure
generated by the engine and the
electric vacuum pump helps reduce
the ef f ort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.All f our brakes have audible brake
wear indicators.
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.
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.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.
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 . 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 your brakes af ter 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 and alert in your driving.

The anti-lock brake system (ABS)
helpspreventthewheelsfrom
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much f aster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the f ront-to-rear
braking distribution according to
vehicle loading.You will f eel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal: it is the ABS rapidly
pumpingthebrakes.Ondry
pavement, you will need to press on
thebrakepedalveryhardbeforethe
ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
If this indicator comes on, the anti-
lock f unction of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.
Let the ABS work f or you by always
keeping f irm, steady pressure on the
brake pedal. This is sometimes
ref erred to as ‘‘stomp and steer.’’ You will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
inf ormation display (see page ).
If the indicator comes on while
driving, test the brakes as instructed
on page .
