Compass operation can be affected
by driving near power lines or
stations, across bridges, through
tunnels, over railroad crossings, past
large vehicles, or driving near large
objects that can cause a magnetic
disturbance. It can also be affected
by accessories such as antennas and
roof racks that are mounted by
magnets.
In most areas, there is a variation
between magnetic north and true
north. Zone selection is required so
the compass can compensate for this
varia tion. To check and select the
zone, do this:
Press and hold the and
buttons simultaneously until
the temperature display changes
(about 5 seconds). Verif y the zone f or your area on
the map on page .
Press the button to cycle the
count down, or the button to
cycle the count up. Once the
correct zone is displayed, continue
to step 4.
Press the OFF button to save the
zone selection.
To exit the zone setting mode,
either press the button and
button simultaneously f or
about 5 seconds, or press any
climate control button on either
side of the display other than the or button.

Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:
You should also f ollow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced.Do not change the oil until the
multi-inf ormation display indicates
it is needed. Avoidhardbrakingforthefirst

acceleration.
Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane of 91 or higher. If this
octane grade is unavailable, regular
unleaded gasoline with a pump
octane of 87 or higher may be used
temporarily. The use of regular
unleaded gasoline can cause metallic
knocking noises in the engine and
will result in decreased engine
perf ormance. The long-term use of
regular-grade gasoline can lead to
engine damage.
Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane number of 91 or higher.
Useof aloweroctanegasolinecan
cause occasional metallic knocking
noises in the engine and will result in
decreased engine perf ormance. Use
of a gasoline with a pump octane
number less than 87 can lead to engine damage.
We recommend quality gasolines
containing detergent additives that
help prevent f uel system and engine
deposits.
In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contact
your dealer f or service.Type S

Your vehicle’s starting system has an
auto control mode. When you turn
the ignition switch to the START
(III) position, this feature keeps the
engine’s starter motor running until
the engine starts. Follow these
instructions to start the engine: 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

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 for about 6 to 9
seconds until the engine starts. If
you hold the ignition switch in
the START (III) position for more

To shif t f rom any position, press
f irmly on the brake pedal. You
cannot shif t out of Park when the
ignition switch is in the LOCK (0) or
ACCESSORY (I) position.
These indicators on the instrument
panel show which position the shif t
lever is in. The illuminated number
under the tachometer shows you the
gear you have selected in the
Sequential SportShif t mode.
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.
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.

µWhen you move the shif t lever f rom
‘‘D’’ to the Sequential SportShift
mode, the display shows the selected
gear.
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.
When you move the
shif t lever to this position, the
transmission shifts to the lowest
gear that can be selected without
exceeding the engine redline. At
normal speeds, it selects third gear.
As the vehicle slows, it selects
second gear at about 56 mph
(90 km/h), and f irst gear at about 29
mph (47 km/h). Accelerating in f irst
gear, the transmission upshif ts to
second gear at about 37 mph
(59 km/h). You must move the shif t
lever to D f or the transmission to
upshif t to third gear. On Type-S, at
closed throttle, it selects second gear
at about 61 mph (98 km/h), and first
gear at about 37 mph (59 km/h).

To release the reverse lockout, make

the LOCK (0) position. Set the parking brake.
This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal does not work. This procedure
is also used to release the reverse
lockout. 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.
When you are in Sequential
SportShif t mode, and the vehicle is
stopped, push f orward on the shif t
lever to shif t to second gear. You will
see ‘‘2’’ in the display. Starting out in
second gear will help to reduce

Check the brakes after driving
through deep water. Apply the
brakes moderate ly to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
Your
vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
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.
Resting
your foot on the brake pedal
applies the brakes slightly. This
builds up heat, and reduces brake
effectiveness and brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you. The
hydraulic system that operates
the brakes has two separate circuits.
Each 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, but the brake pedal
may not f eel normal (see page f or more inf ormation). 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 and braking
ef f ectiveness could be reduced. It is
normal for the brakes to occasionally
squeal or squeak when you apply
them.
