Oil CheckWait 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, and
check the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
seeAdding Engine Oilon page 517.Engine Coolant Check
Look 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 Coolanton page 520 for
information on adding the proper
coolant.
Refer toOwner's Maintenance
Checkson page 513 for information

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 multi-
information display (seeOwner's
Maintenance Checkson page 513).For example:
●Use the recommended viscosity
motor oil, displaying the API
Certification Seal (see page 517).●Maintain proper tire inflation－
An underinflated 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.●Always drive in the highest gear
possible－If your vehicle has a
manual transmission, you can
boost your fuel economy by up
shifting as early as possible.●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.

Check Starting System MessageIf there is a problem with the starting
system, you will see a‘‘CHECK
STARTING SYSTEM’’message on
the multi-information display when
the ignition switch is turned to the
ON (II) position. You will also see
this message when the auto control
mode of the starting system has a
problem.If this message is on, the ignition
switch has to be held in the START
(III) position manually until the
engine starts. The ignition switch can
be held in that position up to 15
seconds.
Even though you may be able to start
the engine manually without the auto
control mode of the starting system,
have your dealer inspect your
vehicle.Shift Lever Position Indicators

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.

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.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly 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-
information display along with a
‘‘CHECK TIRE PRESSURE’’
message.
Low Tire Pressure/
TPMS Indicator
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is significantly underinflated.
You should stop and check your tires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle's tire information
placard.
It is possible that the pressures
shown on the multi-information
display and the pressures you
manually measure are slightly
different.
If the difference is significant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-information display go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible.If you think you can safely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
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 551).
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.
