Occupant safety
Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
The passenger lap-shoulder belt has a
special seat belt retractor for secure fas-
tening of child restraints.
To fasten a child restraint follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The seat belt is now locked. Push
down on child restraint to take up any
slack.
To deactivate, release seat belt buckle and
let seat belt retract completely.
The seat belt can again be used in the
usual manner.The use of infant or child restraints is re-
quired by law in all 50 states, the District of
Columbia, the U.S. territories, and all
Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system which is properly secured
by a lap-shoulder belt and that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213
and 210.2.Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned on these
parts.
If children open a door, they could

injure other persons

get out of the car and injure themselves
or be injured by following traffic
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place.
For more information, please refer to the
“Useful features” section (
page 253)
through (
page 255).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of

strong braking maneuvers

sudden changes of direction

an accident
Warning!G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.

Memory function*
Memory function*
Prior to operating the vehicle, the driver
should check and adjust the seat height,
seat position fore and aft, and seat back-
rest angle if necessary, to ensure adequate
control, reach and comfort. The head re-
straint should also be adjusted for proper
height. See also the section on air bags
(
page 66) for proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, operation
and comfort. Both the interior and exterior
rear view mirrors should be adjusted for
adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in an appropri-
ate infant or child restraint system which is
properly secured by a lap-shoulder belt
and that complies with U.S. Federal Motor
Vehicle Safety Standards 213 and 255
and Canadian Motor Vehicle Safety
Standards 213 and 210.2.With the memory function you can store up
to three different configurations.
Each store position on the driver’s side
includes the following settings:

Seat position

Exterior rear view mirrors’ position
Each store position on the passenger side
includes the following setting:

Step 5:
After indicator lamp1 changes from a
slow to a rapidly flashing light, release
the hand-held remote control button
and the signal transmitter button.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe indicator lamp1.
If indicator lamp1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button (2, 3 or4) is pressed and
released.
Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.Rolling code programming
To train a garage door opener (or other
rolling code devices) with the rolling code
feature, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:
Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the
“training” button may also be referred
to as “learn”or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
Operator’s Manual. Step 9:
Press the “training” button on the
garage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the follow-
ing step.
Step 10:
Return to the vehicle and firmly press,
hold for 2 seconds and release the
programmed signal transmitter
button (2, 3 or4).
iIf indicator lamp1 flashes rapidly for about
2 seconds and then turns to a constant light,
continue with programming steps 8 through 12
as your garage door opener may be equipped
with the “rolling code” feature.

Tires and wheels
Temperature
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.Tire ply material
1Plies in sidewall
2Plies under tread
This marking tells you about the type of
cord and number of plies in the sidewall
and under the tread.
Warning!G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.

on tires are specific to each vehicle and may vary
from data shown in above illustration.

Tire and loading terminology
Accessory weight

factory-installed equipment (whether
installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa), or
bars.
Aspect ratio
Dimensional relationship between tire
section height and section width
expressed in percentage.Bar
Another metric unit for air pressure. There
are 14.5038 pounds per square inch (psi)
to 1 bar; there are 100 kilopascals (kPa)
to 1 bar.
Bead
The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the
rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle
has been sitting for at least three hours or
driven no more than 1 mile (1.6 km).
Curb weight
The weight of a motor vehicle with stan-
dard equipment including the maximum
capacity of fuel, oil, and coolant, and, if so
equipped, air conditioning and additional
optional equipment, but without passen-
gers and cargo.DOT (Department of Transportation)
A tire branding symbol which denotes the
tire meets requirements of the
U.S. Department of Transportation.
GAWR (G
ross Axle Weight Rating)
The GAWR is the maximum permissible
axle weight. The gross vehicle weight on
each axle must never exceed the GAWR for
the front and rear axle indicated on the
certification label located on the driver’s
door B-pillar.
GVW (G
ross Vehicle Weight)
The GVW comprises the weight of the
vehicle including fuel, tools, spare wheel,
installed accessories, passengers and
cargo and, if applicable, trailer tongue
load. The GWV must never exceed the
GWVR indicated on the certification label
