Convenience Net
Your vehicle may have a convenience net located on the
back wall of the cargo area. There are six metal rings in
the cargo area that the net can be attached to. Two are
on the oor behind the rear seat, two are on the oor near
the liftgate and the last two are near the liftgate glass.
The net can be positioned on the liftgate using two rings
securing the cargo in a envelope or using four rings,
keeping the cargo from falling over during sharp turns or
quick starts and stops. The net can also be positioned
using the four rings on the oor, with cargo underneath.
The net is not for larger, heavier loads.
Sunroof
The vehicle may have a power sunroof.
The switches that operate
the sunroof are located
in the headliner.
To open or close the sunroof, the ignition must be in
RUN, in ACC, or Retained Accessory Power (RAP)
must be active. SeeRetained Accessory Power (RAP)
on page 2-24.

If your vehicle has a rear seat that will accommodate a
rear-facing child restraint, a label on your sun visor
says, “Never put a rear-facing child seat in the front.”
This is because the risk to the rear-facing child is
so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag if the system detects a rear-facing child
restraint, no system is failsafe, and no one can
guarantee that an airbag will not deploy under
some unusual circumstance, even though it is
turned off. We recommend that rear-facing
child restraints be secured in the rear seat,
even if the airbag is off.If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, never put a
child in a rear-facing child restraint in the right front
passenger seat the unless passenger airbag status
indicator shows off. Never put a rear facing child
restraint in the right front passenger seat unless the
airbag is off. Here is why:{CAUTION:

designed to turn off the passenger’s frontal
airbag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one

rear-facing child restraints be transported in
vehicles with a rear seat that will
accommodate a rear-facing child restraint,
whenever possible.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency supplies in
your vehicle.
Also seeTires on page 5-46.Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some winter
outer clothing, a small shovel, a ashlight, a red
cloth, and a couple of reective warning triangles. And,
if you will be driving under severe conditions, include
a small bag of sand, a piece of old carpet, or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where the tires meet the
road probably have good traction.
However, if there is snow or ice between the tires and
the road, you can have a very slippery situation. You will
have a lot less traction, or grip, and will need to be
very careful.
4-26

The Certication/Tire label also tells you the maximum
weights for the front and rear axles, called the Gross
Axle Weight Rating (GAWR). To nd out the actual loads
on your front and rear axles, you need to go to a
weigh station and weigh your vehicle. Your dealer can
help you with this. Be sure to spread out your load
equally on both sides of the centerline.
Never exceed the GVWR for your vehicle or the GAWR
for either the front or rear axle.
{CAUTION:
Do not load your vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either
the maximum front or rear Gross Axle Weight
Rating (GAWR). If you do, parts on your
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of your vehicle.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.If you put things inside your vehicle — like suitcases,
tools, packages, or anything else — they will go as fast
as the vehicle goes. If you have to stop or turn
quickly, or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. If you have a lot of options, equipment,
passengers, or cargo in your vehicle, it will reduce the
tongue weight your vehicle can carry, which will also
reduce the trailer weight your vehicle can tow. And if you
tow a trailer, you must add the tongue load to the
GVW because your vehicle will be carrying that weight,
too. SeeLoading Your Vehicle on page 4-32for
more information about your vehicle’s maximum
load capacity.If you are using a weight-carrying hitch, the trailer
tongue (A) should weigh 10 to 15 percent of the total
loaded trailer weight (B).
After you have loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights are
proper. If they are not, you may be able to get them right
simply by moving some items around in the trailer.
Trailering may be limited by the vehicle’s ability to carry
tongue weight. Tongue weight cannot cause the vehicle
to exceed the GVWR (Gross Vehicle Weight Rating) or
the RGAWR (Rear Gross Axle Weight Rating). The effect
of additional weight may reduce your trailering capacity
more than the total of the additional weight.
