is done, it can help you learn about the features
and controls for the vehicle. Pictures and words work
together in the owner manual to explain things.
Index
A good place to quickly locate information about the
vehicle is the Index in the back of the manual. It is an
alphabetical list of what is in the manual and the

ii
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just touching
the child’s thighs. This applies belt force to the child’s
pelvic bones in a crash.
Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle’s
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.
{CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby does not
weigh much — until a crash. During a crash a
baby will become so heavy it is not possible to
hold it. For example, in a crash at only
25 mph (40 km/h), a 12 lb (5.5 kg) baby will
suddenly become a 240 lb (110 kg) force on a
person’s arms. A baby should be secured in
an appropriate restraint.

Remote Keyless Entry System
Your keyless entry system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modi cations to this system by other than
an authorized service facility could void authorization to
use this equipment.At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-6.
If you are still having trouble, see your dealer or a
quali ed technician for service.
2-5
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
The Driver Information Center (DIC) will display a KEY
FOB # BATTERY LOW message when the transmitter
battery is low.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.To replace the battery in the remote keyless entry
transmitter do the following:
1. Insert a thin coin in the slot between the covers of the
transmitter housing. Gently pry the transmitter apart.
2. Remove and replace the battery with a three-volt
CR2032 or equivalent battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it does not start within 10 seconds, push the
accelerator pedal all the way to the oor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.When starting your engine in very cold weather
(below 0°F or−18°C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of
the key.
2. If your engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the
vehicle starts brie y but then stops again, do the
same thing, but this time keep the pedal down
for ve or six seconds. This clears the extra
gasoline from the engine.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.

Manual Rearview Mirror with
Compass and Temperature
The vehicle may have a manual rearview mirror with an
eight-point compass and temperature display located
in the upper right.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Mirror Operation
While sitting in a comfortable position, adjust the rearview
mirror so you can see clearly behind your vehicle. Grip it
in the center and move it up or down and side to side.
The day/night control, located at the bottom of the mirror,
adjusts the mirror to reduce headlamp glare from behind
during evening or dark conditions. Push the control for
daytime use; pull it for night use.
Temperature and Compass Display
O
(On/Off):Press this button to turn the compass and
temperature display on or off. The compass display,
can show a maximum of two characters. For example,
NE is displayed for north-east.
When the ignition and the compass/temperature feature
are on, character boxes will appear for about two
seconds. After two seconds, the mirror will display the
direction the vehicle is facing and the outside
temperature.
To set the temperature in Fahrenheit or Celsius,
do the following:
1. Press and hold the on/off button until either a
ashing F or C appears.
2. Press the button again to change the display to the
desired unit of measurement. After about four
seconds of inactivity, the new unit will be locked in
and the compass/temperature display will return.
