Replacing front parking lamp/turn signal bulb
For driver side replacement of the front parking lamp/turn signal
bulb, do the following:
WARNING:To reduce the risk of vehicle damage and/or
personal burn injuries do not start your engine with the air
cleaner removed and do not remove it while the engine is running.
1. Release the clamps (2) that secure the air filter housing cover.
2. Carefully separate the two halves of the air filter housing.
3. Locate the mass air flow sensor electrical connector on the air outlet
tube (1). This connector will need to be unplugged.
4. Remove the air filter assembly.
5. Remove the bolts on the air inlet (3), then remove the air inlet.
6. Reach over the front bolster to access the bulb.
7. Remove the bulb socket by rotating it counterclockwise, then pull it
straight out of the lamp assembly.
Reverse these steps to complete the process.

For passenger side replacement of the front park/turn signal bulb,
see your authorized dealer.
Replacing stop/tail/turn and side marker bulbs
Your vehicle is equipped with a rear lamp that has a stop/tail/turn and
side marker lamp module containing integral multiple light emitting
diodes (LED). If one or more LEDs burn out, the complete lamp module
has to be replaced. See your authorized dealer for the replacement lamp.
Replacing rear turn signal bulbs
1. Make sure the headlamp switch is in the off position and open the
trunk.
2. Lift out trunk floor carpeting panel to access a luggage scuff plate
(hard molding) shingles and a trunk side panel (dark grey, soft
wheelhouse side trim panel) at the lamp area.
3. Carefully pull/push the trunk side panel (dark grey, soft wheelhouse
side trim panel) outboard to expose the lamp assembly. The most
effective point to grasp the trunk side panel when pulling it out from the
luggage scuff plate is at it’s bottom edge where that edge meets the
exposed sheet metal of the trunk floor.
Note:Do not allow the trunk side panel to remain bent and untucked
from the luggage scuff plate (hard molding) for a long period of time.
Doing so may result in permanent deformation.
4. Remove the bulb socket by
rotating it counterclockwise, then
pulling it out of the lamp assembly.
5. Pull the bulb from the socket and
push in the new bulb.
6. Install the bulb socket into the
lamp assembly by rotating it
clockwise.
7. Carefully push the trunk side
panel (dark grey, soft wheelhouse
side trim panel) back to the shingle position to the luggage scuff plate
(hard molding).
8. Reinstall the trunk floor carpeting panel.
