Reclining Seatbacks
{CAUTION
You can lose control of the
vehicle if you try to adjust the
seat while the vehicle is
moving. The sudden movement
could startle and confuse you,
or make you push a pedal when
you do not want to. Adjust the
driver’s seat only when the
vehicle is not moving.
{CAUTION
Sitting in a reclined position
when your vehicle is in motion
can be dangerous. Even if you
buckle up, your safety belts
cannot do their job when you
are reclined like this.
The shoulder belt cannot do
its job because it will not be
against your body. Instead,
it will be in front of you. In a
crash, you could go into it,
receiving neck or other injuries.
(Continued)
CAUTION (Continued)
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen.
The belt forces would be there,
not at your pelvic bones. This
could cause serious internal
injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear your
safety belt properly.
Adjust the reclining seatback by
turning the knob (C). Do not lean on
the seatback while adjusting it.

Doing Your Own
Service Work
{CAUTION
You can be injured and your
vehicle could be damaged if
you try to do service work on
a vehicle without knowing
enough about it.
Be sure you have sufficient
knowledge, experience, the
proper replacement parts, and
tools before you attempt any
vehicle maintenance task.
Be sure to use the proper
nuts, bolts, and other
fasteners. English and
metric fasteners can be
easily confused. If you use
the wrong fasteners, parts
can later break or fall off.
You could be hurt.If you want to do some of your own
service work, you should use the
proper service manual. It tells
you much more about how to
service your vehicle than this
manual can. To order the proper
service manual, seeService
Publications Ordering Information on
page 12-15.
Your vehicle has an airbag system.
Before attempting to do your
own service work, seeAirbag
System Check on page 1-31.
You should keep a record with all
parts receipts and list the mileage
and the date of any service
work you perform. SeeMaintenance
Record on page 11-15.
Adding Equipment to the
Outside of the Vehicle
Things you might add to the outside
of your vehicle can affect the
airow around it. This can cause
wind noise and can affect fuel
economy and windshield washer
performance. Check with your
dealer/retailer before adding
equipment to the outside of your
vehicle.
