If the malf unction indicator lamp
comes on along with the ‘‘D’’
indicator, there is a problem with the
automatic transmission control
system. Avoid rapid acceleration, and
have the transmission checked by
your dealer as soon as possible.
The ‘‘D’’ indicator comes on f or a
f ew seconds when you turn the
ignition switch to the ON (II)
position. If it f lashes while driving (in
any shif t position), it indicates a
possible problem in the transmission. These indicators in the tachometer
show which position the shif t lever is
in. When the ‘‘D’’ indicator warns of a
possible problem with the
transmission, you will see a ‘‘CHECK

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). Here are the speed ranges f or

Hold the paddle shifter for 2

The automatic transmission will not
allow you to shif t up or down if : Each time you pull either paddle
shifter, the transmission shifts 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 transmission remains in the

When you move the shif t lever f rom
‘‘D’’ to ‘‘S’’ position and pull either
paddle shif ter, the gear position
indicator displays ‘‘M’’ along with the
selected gear number.
To upshift, pull the (right) paddle
shif ter. To downshif t, pull the
(lef t) paddle shif ter.
With the shif t lever in the S position,
you can manually shif t up or down
with the paddle shifters. The
transmission goes into the sequential
shif t mode and holds the selected
gear.
To enter the sequential shif t mode,
pressthereleasebuttononthefront
of the shift lever, move the lever to

move the shift lever to the D position.
While you are driving in the

transmission will not automatically
return to drive mode (D).
The transmission downshif ts to f irst

The automatic transmission will not
allow you to shif t up or down if :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.
If the vehicle speed decreases
below the redline of the selected

downshif ts, and the indicator
displays the selected gear.
You pull both paddle shif ters at

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.
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.
When you accelerate f rom a stop,
the transmission starts in f irst gear,
and you must manually upshif t
between first and fifth gears. Make
sure you upshif t bef ore the engine
speed reaches the tachometer’s red

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.
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.
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.’’ When the ABS indicator comes on,
you will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
inf ormation display.
If the ABS indicator comes on while
driving, test the brakes as shown on

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly. If the tire is flat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message. It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible. When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation
placard.
