6. Check the adjustment of the insideand outside mirrors (see page
154).
7. Check the steering wheel adjustment (see page 124).
8. Make sure the doors and tailgate are securely closed and locked.
9. Fasten your seat belt. Check that your passengers have fastened
their seat belts (see page 15).
10. When you start the engine, check the gauges and indicators in the
instrument panel, and the
messages on the multi-information
display (see pages 63,72and 81). Starting the Engine
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:
1. Apply the parking brake.
2. In cold weather, turn off all
electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in Park. Press on the brake pedal.
4. 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
than 7 seconds, the starter motor,
depending on the outside
temperature, runs for about 10 to
25 seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
The immobilizer system protects your
vehicle from theft. If an improperly-
coded key (or other device) is used, the
engine's fuel system is disabled. For
more information, see page
128.

Starting in Second GearWhen you are in Sequential
SportShift mode, and the vehicle is
stopped, push forward on the shift
lever to shift to second gear. You will
see‘‘2’’ in the display. Starting out in
second gear will help to reduce
wheelspin in deep snow or on a
slippery surface.
If you start out in second gear, the
transmission will be fixed in that
gear.
The transmission will not
automatically downshift to first gear
even when the vehicle speed is
under 10 mph (16 km/h). You need
to shift down to first gear manually.

The super handling-all wheel drive
(SH-AWD) system is a full 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.SH-AWD Torque Distribution
Monitor
The SH-AWD torque distribution
monitor on the multi-information
display shows you the amount of
torque being sent to the wheels.
Each wheel: right front (RF), left
front (LF), right rear (RR), and left
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 differential
temperature is too high. You will also
see an‘‘SH-AWD DIFF TEMP.
HIGH ’’message on the multi-
information display. If this happens,
pull to the side of the road when it is
safe, shift 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-
information display, there is problem
with the SH-AWD system. Your vehicle still has normal front-
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.

Always use the parking brake when
you park your vehicle. Make sure the
parking brake is set firmly, or your
vehicle may roll if it is parked on an
incline.
Set the parking brake before you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.Parking Tips
●Make sure the moonroof and the
windows are closed.●Turn off 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 flammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.●If the vehicle is facing uphill, turn
the front wheels away from the
curb.●If the vehicle is facing downhill,
turn the front wheels toward the
curb.●Check the indicator on the
instrument panel to verify that the
security system is set.●Make sure the parking brake is
fully released before driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.

If the low tire pressure/TPMS
indicator comes on, or the multi-
information display shows a‘‘CHECK
TPMS SYSTEM ’’message, the VSA
system automatically turns on even
when the VSA system is turned off
by pressing the VSA OFF switch
(see page360).If this happens, you
cannot turn the VSA system off by
pressing the VSA OFF switch again.
When you restart the vehicle with
the compact spare tire, the TPMS
system message will also be
displayed on the multi-information
display after several miles
(kilometers) driving.
Changing a Tire with TPMS
If you have a flat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated flat tire with the compact
spare tire (see page425). After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. After several miles
(kilometers) driving, this indicator
begins to flash, then stays on again.
You will also see a
‘‘CHECK TPMS
SYSTEM ’’message on the multi-
information display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
spare tire pressure to be sure it is
correct. This indicator and the warning
message on the multi-information
display will go off, after several miles
(kilometers) driving, when the spare
tire is replaced with the specified
regular tire equipped with the tire
pressure monitor sensor.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualified technician.
Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Have the flat tire repaired by your
dealer as soon as possible.

Braking System
Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The emergency
brake assist system increases the
stopping force when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you. Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
