Roof Rack (Wagon Only)
{CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the roof
rack— like paneling, plywood, a mattress and
so forth — the wind can catch it as you drive
along. This can cause you to lose control.
What you are carrying could be violently torn
off, and this could cause you or other drivers
to have a collision, and of course damage your
vehicle. You may be able to carry something
like this inside. But, never carry something
longer or wider than the roof rack on top of
your vehicle.
A roof rack allows you to load things on top of your
vehicle. The roof rack has side rails attached to the roof.
These let you load some things on top of your vehicle,
as long as they are not wider or longer than the
roof rack.Notice:Loading cargo on the roof rack that weighs
more than 220 lbs (100 kg) or hangs over the rear
or sides of the vehicle may damage your vehicle.
Load cargo so that it rests on the slats as far
forward as possible and against the side rails,
making sure to fasten it securely.
Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, seeLoading Your Vehicle on
page 4-28.
To prevent damage or loss of cargo as you’re driving,
check now and then to make sure cargo is still securely
fastened.
Rear Seat Armrest
Your vehicle may have a rear seat armrest that contains
two cupholders. To access the cupholders, pull the
armrest down from the rear seatback.
Convenience Net
The convenience net can help keep small loads from
moving during sharp turns or quick starts and stops.
Hang the four net hooks in the metal rings on each
corner of the floor.

Include an ice scraper, a small brush or broom, a
supply of windshield washer fluid, a rag, some winter
outer clothing, a small shovel, a flashlight, a red
cloth, and a couple of reflective 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.
What is the worst time for this? Wet ice. Very cold snow
or ice can be slick and hard to drive on.

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 trunk of your vehicle. In a
trunk, put them as far forward as you can.
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.

{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-36.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood. Stay
away from the engine if you see or hear steam
coming from it. Just turn it off and get
everyone away from the vehicle until it cools
down. Wait until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
Notice:If your engine catches re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
