uuWhen Driving uTPMS with Tire Fill Assist
Driving
TPMS with Tire Fill Assist
Monitors the tire pressure while you are
driving. If your vehicle’s tire pressure becomes
significantly low, the Low Tire Pressure/TPMS
indicator comes on and a message appears on
the multi-information display.1 TPMS with Tire Fill Assist
Conditions such as low ambient temperature and
altitude change directly affect tire pressure and can
trigger the Low Tire Pressure/TPMS indicator to come
on.
2 If the Low Tire Pressure/Tire Pressure
Monitoring System (TPMS) Indicator
Comes On or Blinks P. 588
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The Low Tire Pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS audibly and visually informs you of
changes in tire pressure of the individual ti re that you
are adjusting using audibl e and visual indications.
If a change in tire pressure has been significant, the
system beeps and the hazard lights flash continuously
for five seconds when the specified tire pressure is
reached. Stop filling the tire.

uuMaintenance Under the Hood uRecommended Engine Oil
Maintenance
Recommended Engine Oil
Oil is a major contribu tor to your engine’s
performance and longevity. If you drive the
vehicle with insufficient or deteriorated oil,
the engine may fail or be damaged.
This seal indicates the oil is energy conserving
and that it meets the American Petroleum
Institute’s latest requirements.
Use a Genuine Honda Motor Oil or another
commercial engine oil of suitable viscosity for
the ambient temperature as shown.
■Synthetic oil
You may also use synthetic motor oil if it is labeled with the API Certification Seal
and is the specified viscosity grade.
• Genuine Honda Motor Oil
• Premium-grade 0W-20 detergent oil with an API Certification Seal on the
container.1 Recommended Engine Oil
Engine Oil Additives
Your vehicle does not require oil additives. In fact,
they may adversely affect the engine performance
and durability.

uuCleaning uExterior Care
Maintenance
The inside lenses of exterior lights (headlig hts, brake lights, etc.) may fog temporarily
if you have driven in the rain, or after the vehicle has been run through a car wash.
Dew condensation also may build up inside the lenses when there is a significant
enough difference between the ambient and inside lens temperatures (similar to
vehicle windows fogging up in rainy conditions). These conditions are natural
processes, not structural design problems in the exterior lights.
Lens design characteristics may result in mo isture developing on the light lens frame
surfaces. This also is not a malfunction.
However, if you see large amounts of wa ter accumulation, or large water drops
building up inside the lenses, have your vehicle inspected by a dealer.

Emissions Testing
Testing of Readiness Codes
Your vehicle has readiness codes as part of the onboard self diagnostic system.
Some States use these codes for testing to verify whether your vehicle’s emissions
components are working properly.
The codes may not be read properly if testing is performed just after the battery has
gone dead or been disconnected.
To check if they are set, set the power m ode to ON, without starting the engine. The
malfunction indicator lamp will come on for several seconds. If it then goes off, the
readiness codes are set. If it blinks fi ve times, the readiness codes are not set.
If you are required to have your vehicle te sted before the readiness codes are ready,
prepare the vehicle for retest ing by doing the following:
1. Fill the gas tank to approximately 3/4 full.
2. Park the vehicle and leave the engine off for 6 hours or more.
3. Make sure the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4. Start the engine without touching the ac celerator pedal, and let it idle for 20
seconds.
5. Keep the vehicle in
(P. Increase the engine speed to 2,000 rpm, and hold it there
for about 3 minutes.
6. Let the engine idle with your foot off the accelerator for 20 seconds.
1Testing of Readiness Codes
The readiness codes are erased when the battery is
disconnected, and set again only after several days of
driving under a variety of conditions.
If a testing facility determines that the readiness
codes are not set, you may be requested to return at
a later date to complete the test.
If the testing facility determines the readiness codes
are still not set, see a dealer.
