Hood Release
To open the hood, do the following.
1. Pull the interior hood
release lever with
this symbol on it.
It is located under
the instrument panel
on the driver’s side
of the vehicle.
2. Then go to the front of the vehicle and push
the secondary hood release lever to the left.
It is located under the front center of the hood
toward the driver’s side of the vehicle.
3. After you have partially lifted the hood, a gas
strut will automatically take over to lift and
hold the hood in the fully open position.
Before closing the hood, be sure all the ller
caps are on properly. Lower the hood until
the lifting force of the strut is reduced,
then release the hood to latch fully. Check
to make sure the hood is closed and repeat
the process if necessary.

To adjust the vertical aim on the headlamps:
1. Open the hood. SeeHood Release on
page 289for more information.
2. Locate the aim dot on the lens of the
low-beam headlamp.
3. Record the distance from the ground to the
aim dot on the low-beam headlamp.4. At a wall, measure from the ground upward (A)
to the recorded distance from Step 3 and
mark it.
5. Draw or tape a horizontal line (B) on the wall
the width of the vehicle at the height of the
mark in Step 4.
Notice:Do not cover a headlamp to improve
beam cut-off when aiming. Covering a
headlamp may cause excessive heat build-up
which may cause damage to the headlamp.
6. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being adjusted. Do not place
it directly on the headlamp. This allows
only the beam of light from the headlamp
being adjusted to be seen on the at surface.
