●When the ABS or VSA is activated.●When the VSA indicator comes on.
If ACC is canceled by any these
conditions, wait until the condition
improves, then press the RES/
ACCEL button to restore ACC.
When you do this, the vehicle will
resume its set cruising speed.
If you select the ACCESSORY or
VEHICLE OFF(LOCK) mode by
operating the engine start/stop
button (see page 194) after ACC
was automatically canceled, the set
speed is erased, and you must
enter it again (see page 386).ACC Indicator
The ACC indicator (orange) normally
comes on for a few seconds when
you select the ON mode by operating
the engine start/stop button (see
page 194). If it comes on at any other
time, there is a problem in the ACC
system. If this happens, take the
vehicle to your dealer to have it
checked.
The ACC system cannot be used
while this indicator (orange) is on.

If the engine has just been started, it
may take a short time for the system
to display the rear view.
The camera display brightness is
adjusted automatically by sensors. If
you use the camera display
continuously at high temperatures,
the image will gradually dim.
The inside mirror will be hot when
you use the monitor for an extended
period of time.
If a bright light (such as sunlight) is
reflected on the mirror, the image
may be difficult to see.
Rearview Camera Guide Line
The camera display has parking
guide lines that indicate distance
from your vehicle.
1st Line 7.8 in (0.2 m)
2nd Line 39 in (1 m)
3rd Line 79 in (2 m)
4th Line 118 in (3 m)
NOTE:●The rearview camera has a unique
lens that makes objects appear
closer than they actually are.●The rearview camera display has
limited coverage, and the size and
position of objects may appear
different than they actually are.
Make sure to check the
surrounding area carefully.
To turn off the guide lines, press and
hold the power button for more than
3 seconds. The guide lines appear
every time you shift to reverse, even
if you turned them off the last time.

Before you begin driving your
vehicle, you should know what
gasoline to use and how to check the
levels of important fluids. You also
need to know how to properly store
cargo or packages. The information
in this section will help you. If you
plan to add any accessories to your
vehicle, please read the information
in this section first.Break-in Period

The message should go off after
several days of normal driving once
you tighten or replace the fuel fill
cap. To scroll to another message,
press the INFO button. The
‘‘TIGHTEN FUEL CAP ’’message
will appear each time you restart the
engine until the system turns the
message off.
If the system still detects a leak in
the vehicle's evaporative emissions
system, the malfunction indicator
lamp (MIL) comes on. If the fuel fill
cap was not already tightened, turn
the engine off, and check or
retighten the fuel fill cap until it
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go off,
have your vehicle inspected by a
dealer. For more information, see
page 593. Opening and Closing the Hood
1. Park the vehicle, and set the
parking brake. Pull the hood
release handle located under the
lower left corner of the dashboard.
The hood will pop up slightly.
2. Put your fingers under the frontedge of the hood near the center.
Slide your hand to your left until
you feel the hood latch handle.
Push this handle up until it
releases the hood. Lift up the
hood.
If the hood latch handle moves stiffly,
or if you can open the hood without
lifting the handle, the mechanism
should be cleaned and lubricated.

3. Lift the hood up most of the way.The hydraulic supports will lift it
up the rest of the way and hold it
up.
To close the hood, lower the hood to
about a foot (30 cm) above the
fender, then press down firmly with
your hands. Make sure it is securely
latched. Oil Check
Wait a few minutes after turning the
engine off before you check the oil.
1. Remove the dipstick (orange loop).
2. Wipe off the dipstick with a clean
cloth or paper towel.
3. Insert the dipstick all the way back into its hole.
4. Remove the dipstick again, andcheck the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see Adding Engine Oil on page 545.

Engine Coolant CheckLook at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeAdding
Engine Coolant on page 548 for
information on adding the proper
coolant.
Refer to Owner's Maintenance
Checks on page 541 for information
about checking other items on your
vehicle.

Fuel Economy Factors
The following factors can lower your
vehicle's fuel economy:●Aggressive driving (hard
acceleration and braking)●Excessive idling, accelerating and
braking in stop-and-go traffic●Cold engine operation (engines
are more efficient when warmed
up)●Driving with a heavy load or the air
conditioner running●Improperly inflated tiresImproving Fuel EconomyVehicle MaintenanceA properly maintained vehicle
maximizes fuel economy. Poor
maintenance can significantly reduce
fuel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the information
display (seeOwner's Maintenance
Checks on page 541). For example:
●Use the recommended viscosity
motor oil, displaying the API
Certification Seal (see page 545).●Maintain proper tire inflation
－
An under-inflated tire increases
‘‘ rolling resistance, ’’which reduces
fuel economy.●Avoid carrying excess weight in
your vehicle －It puts a heavier
load on the engine, increasing fuel
consumption.●Keep your vehicle clean －In
particular, a build-up of snow or mud
on your vehicle's underside adds
weight and rolling resistance.
Frequent cleaning helps your fuel
economy.Drive Efficiently●Drive moderately －Rapid
acceleration, abrupt cornering, and
hard braking increase fuel
consumption.
●Observe the speed limit －
Aerodynamic drag has a big effect
on fuel economy 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.●Avoid excessive idling －Idling
results in 0 miles per gallon (0 kms
per liter).

●Minimize the use of the air
conditioning system－The A/C
puts an extra load on the engine
which makes it use more fuel. Use
the fresh-air ventilation when
possible.●Plan and combine trips －
Combine several short trips into
one. A warmed-up engine is more
fuel efficient than a cold one.
Calculating Fuel EconomyMeasuring TechniquesDirect calculation is the
recommended source of information
about your actual fuel economy.
Using frequency of fill-ups or taking
fuel gauge readings are NOT
accurate measures of fuel economy.
Fuel economy may improve over the
first several thousand miles
(kilometers).
Checking Your Fuel Economy1)Fill the fuel tank until the nozzle automatically clicks off.
2)Reset trip counter to zero.
3)Record the total gallons (liters) needed to refill.
4)Follow one of the simple calculations above.
