Make sure the ‘‘UP’’ mark on the
loop is f acing up when you insert
the dipstick.
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,
see on page . 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, see
on page f or
inf ormation on adding the proper
coolant. Refer to
on page f or inf ormation

Fuel economy is not a f ixed number.
It varies based on driving conditions,
driving habits and vehicle condition.
Theref ore, it is not possible f or one
set of estimates to predict f uel
economy precisely f or all drivers in
all environments.
Provides an estimated annual f uel
cost, based on 15,000 miles (20,000
km) per year multiplied by the cost
pergallon(basedonEPAfuelcost
data) divided by the combined f uel
economy.

economy ratings and factors that

The EPA f uel economy estimates

are a usef ul tool f or comparison

estimates include:

highway driving. The scale
represents the range of combined
f uel economy f or other vehicles in

Represents a

Improperly inf lated tires
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
inf ormation display (see
on page ).
For example: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
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.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Idling
results in 0 miles per gallon.
‘‘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.

meet f actory specif ications, and
could adversely af f ect your vehicle’s
handling and stability.When properly installed, cellular
phones, alarms, two-way radios, and
low-powered audio systems should
not interf ere with your vehicle’s
computer controlled systems, such
as your airbags, anti-lock brakes, and
tire pressure monitoring system.Bef ore installing any accessory:
Make sure the accessory does not
obscure any lights, or interf ere
with proper vehicle operation or
perf ormance.

Removing parts f rom your vehicle,
or replacing components with non-
Acura components could seriously
af f ect your vehicle’s handling,
stability, and reliability.
Herearesomeexamples:Lowering the vehicle with a non-
Acura suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.
Raising your vehicle with a non-
Acura suspension kit can af f ect
the handling and stability. Non-Acura wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).
Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
Modif ying your steering wheel or
any other part of your vehicle’s
safety features can make the
systems inef f ective.
If you plan to modif y your vehicle,
consult your dealer.

Locate the statement ‘‘The
combined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs.’’ on your vehicle’s
placard.
Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.
Subtract the combined weight of
the driver and passengers f rom
XXX kg or XXX lbs.
The resulting f igure equals the
available amount of cargo and
luggage load capacity. For
example, if the ‘‘XXX’’ amount
equals 1,400 lbs. and there will be
f ive 150 lb. passengers in your
vehicle, the amount of available
cargo and luggage load capacity is
650 lbs.
(1,400 750 (5 150) = 650 lbs.)
The maximum load f or your vehicle
is 870 lbs f or U.S. vehicles, and 395
kg f or Canadian vehicles.
See Tire And Loading Inf ormation
label attached to the driver’s
doorjamb.

Determine the combined weight
of luggage and cargo being loaded
on the vehicle. That weight may
not saf ely exceed the available
cargo and luggage load capacity
calculated in Step 4.
If your vehicle will be towing a
trailer, load f rom your trailer will
be transf erred to your vehicle.
Consult this manual to determine
how this reduces the available
cargo and luggage load capacity of
your vehicle.In addition, the total weight of the
vehicle, all occupants, accessories,
cargo, and trailer tongue load must
not exceed the Gross Vehicle

Store or secure all items that could
be thrown around and hurt
someone during a crash.
Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop.
Be sure items placed on the f loor
behind the f ront seats cannot roll
underneath and interf ere with the
proper operation of the seats, the
sensors under the seats, or the
driver’s ability to operate the
pedals.
Do not put any items on top of the
cargo area cover. They can block
your view and be thrown around
the vehicle during a crash.If you carry large items that
prevent you f rom closing the
tailgate, exhaust gas can enter the
passenger area. To avoid the

for further information.
Distribute cargo evenly on the
f loor of the cargo area, placing the
heaviest items on the bottom and
as far forward as possible. Tie
down items that could be thrown
about the vehicle during a crash or
