Aggressive driving (hard

Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines

Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
An under-inf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption. In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.
The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the multi-
inf ormation display (see
on page ).
For example: Idling
results in 0 miles per gallon. If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.

This section gives you tips on
starting the engine under various
conditions, and how to operate the
automatic transmission. It also
includes important inf ormation on
parking your vehicle, the braking
system, the Super handling-all wheel
drive (SH-AWD) system, the vehicle
stability assist (VSA) system, the tire
pressure monitoring system (TPMS),
the collision mitigation brake system
(CMBS), and f acts you need if you
are planning to tow a trailer.........................

These indicators on the instrument
panel show which position the shif t
lever is in. In the Sequential
SportShif t Mode, the ‘‘M’’ indicator
next to the ‘‘D’’ indicator comes on,
and the illuminated number under
the low oil pressure indicator shows
you the gear you have selected.To shif t f rom Park to any position,
press firmly on the brake pedal and
slide the lever along the guide on the
console. You cannot shif t out of Park
when the ignition switch is in the
LOCK (0) or the ACCESSORY (I)
position.
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.
When the ‘‘D’’ indicator warns of a
possible problem with the
transmission, you will see a ‘‘CHECK
TRANSMISSION’’ message on the
multi-inf ormation display (see page
).

To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can turn the ignition
switch to the LOCK (0) position, or
remove the built-in key from the
ignition switch. Press the brake
pedal to shif t f rom Park to reverse.
To shif t f rom neutral to reverse,
come to a complete stop and then
shif t.
Your vehicle has a reverse lockout so
you cannot accidentally shif t to
reverse f rom neutral or any other
driving position when the vehicle
speed exceeds 5 6 mph (8 10
km/h).
If you cannot shif t to reverse when
the vehicle is stopped, press the
brake pedal, slowly shif t to neutral,
andthenshifttoreverse. If there is a problem in the reverse
lockout system, or your vehicle’s
battery is disconnected or goes dead,
you cannot shif t to reverse. (Ref er to
on page ).
Use neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t 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.
Use this position f or
your normal driving. The
transmission automatically selects a
suitable gear (1 through 5) f or your
speed and acceleration. You may
notice the transmission shif ting up at
higher engine speeds when the
engine is cold. This helps the engine
warm up f aster.
If you have done all of the above and
still cannot move the lever out of
Park, see on
page . This position mechani-
cally locks the transmission. Use
Park whenever you are turning of f or
starting the engine. To shif t out of
Park, you must press on the brake
pedal and have your f oot of f the
accelerator pedal. Move the shif t
levertotherighttoshiftoutof Park.

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.
In Sequential SportShif t mode, each
time you push f orward on the shif t
lever, the transmission shifts to a
higher gear. Pull back on the lever to
downshif t. The number of the gear
selected is displayed on the
instrument panel.
When you move the shif t lever f rom
‘‘D’’ to ‘‘M’’ position, the display
shows the selected gear. While in the Sequential SportShif t
mode, you can also shif t up or down
using the (right side) or (lef t
side) paddle shif ters on the right and
lef t side of the steering wheel.
For up shif t, press the right side ( )
paddle shif ter.
For down shif t, press the lef t side
( ) paddle shif ter.

When you accelerate away f rom a

gear. You have to manually upshif t
between first and fifth gears. Make
sure you upshif t bef ore the engine
speed reaches the tachometer’s red
zone.
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 is under
8mph(13km/h).
If you try to manually downshif t at a
speed that would cause the engine to
exceed the redline in a lower gear,
the transmission does not downshif t.
If the vehicle speed slows to below
the redline of the selected lower gear
position while the indicator is

downshif ts, and the display shows
the selected lower gear.

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

µIf 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. Make sure the ignition switch is in
the LOCK (0) position.
Set the parking brake.
Bef ore downshif ting, make sure the
engine will not go into the
tachometer’s red zone. 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 position is
similar to D, except only the f irst
three gears are selected. Use D
when towing a trailer in hilly terrain,
or to provide engine braking when
going down a steep hill. D can also
keep the transmission f rom cycling
between third, f ourth, and f if th gears
in stop-and-go driving.
ForfasteraccelerationwheninD or
D, you can get the transmission to
automatically downshif t by pushing
the accelerator pedal to the floor.
The transmission will shif t down one,
two, or three gears, depending on
your speed. To release the reverse lockout, make
sure the ignition switch is in the
ACCESSORY(I) position.
