5W-20 oil is f ormulated f or year-
round protection of your vehicle to
improve cold weather starting and
f uel economy.
You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal
and it is the proper weight. You must
f ollow the oil and f ilter change
intervals shown on the multi-

Acura Motor Oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Acura Motor Oil in your vehicle f or

Remove the oil drain bolt and
washer from the bottom of the
engine. Drain the oil into an
appropriate container.
Always change the oil and f ilter
according to the maintenance
messages shown on the multi-
inf ormation display. The oil and f ilter
collect contaminants that can
damage your engine if they are not
removed regularly.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
technician.
Run the engine until it reaches
normal operating temperature,
then shut it off.
Open the hood and remove the
engine oil f ill cap. Remove the bolts located on the
underside of the body with a
wrench, then remove the under
cover.

Check the f luid level with the engine
at normal operating temperature.Park the vehicle on level ground.
Start the engine, let it run until the
radiator f an comes on, then shut
of f the engine. For accurate
results, wait about 60 seconds (but
no longer than 90 seconds) bef ore
doing step 2.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition the blade edges.
If the washer f luid is low, a

temporary replacement. However,
motor oil does not contain the proper

To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.
When the tires are rotated, make
sure the air pressures are checked.Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire’s sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
The ABS and VSA system work by
comparing the speed of each wheel.
When replacing tires, use the same
size originally supplied with the
vehicle. Tire size and construction
can af f ect wheel speed and may
cause the system to activate.
It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.
