Secondary Latch
System (H3T)
This vehicle has an underbody
mounted tire hoist assembly that has
a secondary latch system. It is
designed to stop the spare tire from
suddenly falling off the vehicle if
the cable holding the spare tire is
damaged. For the secondary latch to
work, the tire must be stowed with
the valve stem pointing down.
SeeStoring a Flat or Spare Tire
and Tools (H3) on page 5-78
orStoring a Flat or Spare Tire and
Tools (H3T) on page 5-80for
instructions on storing the spare tire
correctly.
{CAUTION
Before beginning this procedure
read all the instructions. Failure to
read and follow the instructions
could damage the hoist assembly
and you and others could get
hurt. Read and follow the
instructions listed next.
To release the spare tire from the
secondary latch:
{CAUTION
Someone standing too close
during the procedure could be
injured by the jack. If the spare
tire does not slide off the jack
completely, make sure no one is
behind you or on either side of
you as you pull the jack out from
the under spare.1. If the cable is not visible, start
this procedure at Step 3.
2. Turn the lug wrench
counterclockwise until
approximately 6 inches (15 cm)
of cable is exposed.
3. Attach the lug wrench to the
jack and raise the jack at
least 10 turns.
4. Place the jack under the vehicle,
ahead of the rear bumper.
Position the center lift point of
the jack under the center of

may lose air over time, so check
its ination pressure regularly.
SeeInflation - Tire Pressure on
page 5-51andLoading the Vehicle
on page 4-35for information
regarding proper tire ination and
loading your vehicle. For instruction
on how to remove, install or store
a spare tire, seeRemoving the Flat

Appearance Care
Interior Cleaning
The vehicle’s interior will continue to
look its best if it is cleaned often.
Although not always visible,
dust and dirt can accumulate on the
upholstery. Dirt can damage
carpet, fabric, leather, and plastic
surfaces. Regular vacuuming
is recommended to remove particles
from the upholstery. It is important
to keep the upholstery from
becoming and remaining heavily
soiled. Soils should be removed as
quickly as possible. The vehicle’s
interior may experience extremes of
heat that could cause stains to
set rapidly.
Lighter colored interiors may require
more frequent cleaning. Use care
because newspapers and garments
that transfer color to home
furnishings may also transfer color
to the vehicle’s interior.When cleaning the vehicle’s interior,
only use cleaners specically
designed for the surfaces being
cleaned. Permanent damage may
result from using cleaners on
surfaces for which they were not
intended. Use glass cleaner only on
glass. Remove any accidental
over-spray from other surfaces
immediately. To prevent over-spray,
apply cleaner directly to the
cleaning cloth.
Notice:Using abrasive cleaners
when cleaning glass surfaces
on the vehicle, could scratch the
glass and/or cause damage to
the rear window defogger.
When cleaning the glass on the
vehicle, use only a soft cloth
and glass cleaner.
Many cleaners contain solvents that
may become concentrated in the
vehicle’s breathing space. Before
using cleaners, read and adhere
to all safety instructions on the label.
While cleaning the vehicle’sinterior, maintain adequate
ventilation by opening the vehicle’s
doors and windows.
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Products that remove odors from
the vehicle’s upholstery and
clean the vehicle’s glass can be
obtained from your dealer/retailer.
Do not clean the vehicle using:
A knife or any other sharp object
to remove a soil from any interior
surface.
A stiff brush. It can cause
damage to the vehicle’s interior
surfaces.
Heavy pressure or aggressive
rubbing with a cleaning cloth.
Use of heavy pressure can
damage the interior and does
not improve the effectiveness of
soil removal.
Service and Appearance Care 5-83

Laundry detergents or
dishwashing soaps with
degreasers can leave residue
that streaks and attracts dirt.
For liquid cleaners, about
20 drops per gallon (3.78 L) of
water is a good guide. Use
only mild, neutral-pH soaps.
Too much cleaner that saturates
the upholstery.
Organic solvents such as naptha,
alcohol, etc. that can damage the
vehicle’s interior.
Fabric/Carpet
Use a vacuum cleaner with a soft
brush attachment frequently to
remove dust and loose dirt.
A canister vacuum with a beater bar
in the nozzle may only be used
on oor carpet and carpeted oor
mats. For any soil, always try
to remove it rst with plain water orclub soda. Before cleaning, gently
remove as much of the soil as
possible using one of the following
techniques:
For liquids: gently blot the
remaining soil with a paper towel.
Allow the soil to absorb into
the paper towel until no more
can be removed.
For solid dry soils: remove as
much as possible and then
vacuum.
To clean:
1. Saturate a lint-free, clean white
cloth with water or club soda.
2. Wring the cloth to remove excess
moisture.
3. Start on the outside edge of the
soil and gently rub toward the
center. Continue cleaning, using
a clean area of the cloth each
time it becomes soiled.4. Continue to gently rub the soiled
area until the cleaning cloth
remains clean.
5. If the soil is not completely
removed, use a mild soap
solution and repeat the cleaning
process that was used with
plain water.
If any of the soil remains, a
commercial fabric cleaner or spot
lifter may be necessary. When
a commercial upholstery cleaner or
spot lifter is to be used, test a
small hidden area for colorfastness
rst. If the locally cleaned area
gives any impression that a ring
formation may result, clean
the entire surface.
After the cleaning process has been
completed, a paper towel can be
used to blot excess moisture
from the fabric or carpet.
