Convenience Net
Your vehicle has a convenience net located on the back
wall of the trunk.
Put small loads, like grocery bags, behind the net. It can
help keep them from falling over.
The net isn’t for larger, heavier loads. Store those in the
trunk as far forward as you can.
You can unhook the net so that it will lieflat when
you’re not using it.
Sunroof
Your vehicle may be equipped with an express-open
sunroof. It includes a sliding glass panel and a
sunshade.
The switch to open the sunroof is located overhead on
the headliner.The switch works only when the ignition is on or when
retained accessory power is active. See“Retained
Accessory Power”inIgnition Positions on page 2-18.
VENT:To raise the sunroof to the vent position only,
push and hold the front of the switch until the sunroof
glass stops. You will need to open the sunshade by hand.
To close the sunroof from the vent position, push and
hold the rear of the switch until the sunroof glass closes.
Open/Express Open:To open the sunroof, push the
rear of the switch once. The sunroof and sunshade will
open by themselves. This is the express-open feature.
To close the sunroof, push and hold the front of the
switch until the sunroof motor stops. The sunshade can
only be closed by hand.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and in the fuse block wiring itself. This greatly reduces
the chance offires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
Instrument Panel Fuse Block
Some fuses are located in
a fuse block on the
passenger’s side of the
vehicle. Pull off the cover
labeled FUSES to
expose the fuses.
