All-Weather Cargo Area
Your vehicle has the ability to operate in many different
congurations--cargo panels on or off, Midgate®up
or down, rear glass in or out. The vehicle has features
to help it resist the elements and protect cargo inside
the cargo area. Your vehicle is designed to quickly
direct water out of the cargo box. The top drain grates,
side rail channels, catch cups, Midgate
®drain, cargo
area oor drains and the rubber cargo mat help do this.
Even when all of these things are working properly
and the cover system is on, there may be some
instances (heavy rains, automated car washes, etc.)
when water may be present in the following areas:
A. Top drain grates
B. Removable front
drain grate (Midgate
®
drain gate)
C. Side rail channels and
catch cups
D. Front drainsE. Water drainage area
around both sides of
the box and the
tailgate side
F. Rear drains
G. Cargo oor

(c)Visually inspect hoses and have them replaced if
they are cracked, swollen, or deteriorated. Inspect all
pipes, ttings, and clamps; replace with genuine parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades,
if contaminated. Replace wiper blades that are worn
or damaged. See Windshield Wiper Blade Replacement
on page 5-55andWindshield and Wiper Blades on
page 5-104for more information.
(e)Make sure the safety belt reminder light and safety
belt assemblies are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired. Have any torn or frayed safety
belts replaced. Also see Checking the Restraint Systems

secondary latch, pivots, spring anchor, release pawl,
midgate hinges, side storage box door hinges, tailgate
hinges, tailgate linkage, outer tailgate handle pivot
points, latch bolt, fuel door hinge, locks, and folding
seat hardware. More frequent lubrication may be
required when exposed to a corrosive environment.Applying silicone grease on weatherstrips with a clean
cloth will make them last longer, seal better, and
not stick or squeak.
(g)Check vent hose at transfer case for kinks and
proper installation.
(h)Change automatic transmission uid and lter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature

for what to use. Inspect hoses. Clean radiator,
condenser, pressure cap, and ller neck. Pressure test
the cooling system and pressure cap.
