WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-
tipped spark plugs as frequently as conven-
tional type spark plugs because they last
much longer. Follow the maintenance
schedule, but do not reuse the spark plugs
by cleaning or regapping.
cAlways replace spark plugs with rec-
ommended or equivalent ones.1. On the 1.8L engine, disconnect the igni-
tion coil connectors. Remove the ignition
coil bolts.
2. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the
boots, not the cables. Mark all cables to
identify their original locations.
3. Remove the spark plugs with a spark
plug socket.
The plug socket has a rubber seal that
holds the spark plug so it does not fall
when it is pulled out. Make sure each
spark plug is snugly fitted into the spark
plug socket.
4. Fit the new plugs, one at a time, into the
spark plug socket and install them.Use
only the specified spark plugs.Turn
each plug several full turns by hand, then
tighten with the spark plug socket to the
correct torque. Do not overtighten.

use of ``SNOW'' tires or ``ALL SEASON''
tires on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires. Skid and
traction capabilities of studded snow tires
on wet or dry surfaces may be poorer than
that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE class ªSº chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In ad-
dition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or ve-hicle handling and performance may be
adversely affected.
Never install tire chains on a TEMPORARY
USE ONLY spare tire. Do not use tire
chains on dry roads.
Tire chains must be installed only on the
front wheels and not on the rear wheels.

WARNING
cIt is extremely dangerous to ride in a
cargo area inside the vehicle. In a
collision, people riding in these ar-
eas are more likely to be seriously
injured or killed.
cDo not allow people to ride in any
area of the vehicle that is not
equipped with seats and seat belts.
c
Be sure everyone in the vehicle is in a
seat with their seat belt properly fas-
tened.
TERMS
It is important to familiarize yourself with the
following terms before loading your vehicle:
cCurb Weight (actual weight of your ve-
hicle) - vehicle weight including: standard
and optional equipment, fluids, emer-
gency tools, and spare tire assembly.
This weightdoes notinclude passen-
gers and cargo.
cGVW (Gross Vehicle Weight) - curb
weight plus the combined weight of pas-
sengers and cargo.
cGVWR (Gross Vehicle Weight Rating) -maximum total weight (load) limit speci-
fied for the vehicle.
cGAWR (Gross Axle Weight Rating) -
maximum weight (load) limit specified for
the front or rear axle.
DETERMINING VEHICLE LOAD
CAPACITY
The load capacity of this vehicle is deter-
mined by weight, not by available cargo
space. For example, a luggage rack, bike
carrier, cartop carrier or similar equipment
does not increase the load carrying capacity
of your vehicle.
To determine vehicle load capacity:
Vehicle weight can be determined by using
a commercial-grade scale, found at places
such as a truck stop, gravel quarry, grain
elevator, or a scrap metal recycling facility.
1) Determine the curb weight of your ve-
hicle.
2) Compare the curb weight amount to the
GVWR specified for your vehicle to de-
termine how much more weight your
vehicle can carry.
3) After loading (cargo and passengers),re-weigh your vehicle to determine if
either GVWR or GAWR for your vehicle
is exceeded. If GVWR is exceeded, re-
move cargo as necessary. If either the
front or rear GAWR is exceeded, shift the
load or remove cargo as necessary.
LOADING TIPS
cThe GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S.
Certification Label.
cDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
WARNING
cProperly secure all cargo to help
prevent it from sliding or shifting. Do
not place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
cDo not load your vehicle any heavier
than the GVWR or the maximum
front and rear GAWRs. If you do,
parts of your vehicle can break, or it
can change the way your vehicle
