Replacing Light Bulbs
Headlight Bulbs
Headlight bulbs are LED type. Have an authorized Acura dealer inspect and replace
the light assembly.
Fog Light Bulbs*
When replacing, use the following bulbs.
1.Turn the steering wheel all the way to the
opposite side from the fog light being
replaced.
Passenger side: Turn the steering wheel to
the left.
Driver side: Turn the steering wheel to the
right.
2. Remove the holding clip and screw, and
pull the inner fender back.
Fog Light: 55 W (H11)
1Headlight Bulbs
The headlight aim is set by the factory, and does not
need to be adjusted. Howeve r, if you regularly carry
heavy items in the cargo area or tow a trailer, have
the aiming readjusted at a dealer or by a qualified
technician.
1 Fog Light Bulbs*
NOTICE
Halogen bulbs get very hot wh en lit. Oil, perspiration,
or a scratch on the glass can cause the bulb to
overheat and shatter.
The fog lights ar e halogen bulbs.

uuCleaning uExterior Care
Maintenance
The inside lenses of exterior lights (headlights, brake light s, 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 natura l processes, not structural design problems in the
exterior lights.
Lens design characteristics ma y result in moisture developing on the light lens frame
surfaces. This also is not a malfunction.
However, if you see large amounts wate r accumulation, or large water drops
building up inside the lenses, have your vehicle inspected by a dealer.

Handling the Unexpected
Inspecting and Changing Fuses
1. Set the power mode to VEHICLE OFF
(LOCK). Turn headlight s and all accessories
off.
2. Remove the fuse box cover.
3. Check the large fuse in the engine

u If there is a burned out fuse, remove it
with the fuse puller and replace it with a
new one.1Inspecting and Changing Fuses
NOTICE
Replacing a fuse with on e that has a higher rating
greatly increases the chances of damaging the
electrical system.
Replace fuse with a spare fuse of the same specified
amperage
Confirm the specified amperage using the charts on
P. 426 to P. 427.
There is a fuse puller on the back of the engine
