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.
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.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications 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 2-5.
If you are still having trouble, see your dealer or a
qualied technician for service.
2-4

Matching Transmitter(s) to
Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
Battery Replacement
Under normal use, the battery in the 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 is probably time to change the battery.
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, do the following:
1. Insert a coin, or similar object, 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.
2-6

For both the manual and automatic transmissions,
depending on the outside temperature, the engine
starter may continue cranking the engine up to
approximately four seconds after you release the
ignition key. This is normal.
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 briey 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. Any resulting damage
would not be covered by your vehicle’s warranty.Engine Coolant Heater
Your vehicle may be equipped with this feature.
In very cold weather, 0°F (–18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
behind the underhood fuse block on the driver’s side
of the vehicle.

Up-Shift Light
This light will show you
when to shift to the next
higher gear for best
fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions permit.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the shift light when you downshift.
If your vehicle has four-wheel drive and is equipped with
a manual transmission, disregard the shift light when
the transfer case is in four-wheel low.
For more information, seeUp-Shift Light (Manual
Transmission) on page 3-31.
Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Do not shift down
more than one gear at a time when you
downshift.
All-Wheel Drive
All-wheel drive sends your engine’s driving power to all
four wheels for extra traction. To get the most out of
all-wheel drive, you must be familiar with its operation.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day. DRL
can be helpful in many different driving conditions, but
they can be especially helpful in the short periods after
dawn and before sunset. Fully functional daytime running
lamps are required on all vehicles rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P) if you have an
automatic transmission.
The light sensor determines it is daytime.
When the DRL are on, only the DRLs will be on. The
other lamps will not be on. The instrument panel will not
be lit up either. For vehicles rst sold in Canada, if
parking lamps are manually turned on, DRL will stay on.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
To turn off the DRL, seeExterior Lamps on page 3-14.
Vehicles rst sold in Canada cannot turn off DRL
unless certain conditions are met. SeeExterior Lamps
on page 3-14.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps, roof marker
lamps and the instrument panel lights. The radio
lights will become more dim when the headlights are off
compared to when the headlights are on.
Your vehicle has a light sensor located on the top of the
instrument panel. Be sure it is not covered, or the
system will be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp system so that driving
under bridges or bright overhead street lights does not
affect the system. The DRL and automatic headlamp
system will only be affected when the light sensor sees a
change in lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness control is in the full bright
position. SeeInstrument Panel Brightness on page 3-18.

Climate Controls
Climate Control System
With this system you can control the heating, cooling,
and ventilation of your vehicle. In-between modes
are available by moving the right control knob between
modes with symbols. The in-between mode will be a
combination of the two modes that the control is
selected between.
Temperature:Turn the left knob on the control panel to
adjust the temperature of the air in the vehicle. Turn
the knob clockwise or counterclockwise to increase or
decrease the temperature.
#(Air Conditioning):Press the left knob on the
control panel to turn the air conditioning system on or
off. An indicator light on the button will come on to
let you know the air conditioning is activated. When the
system is on, this setting cools and dehumidies the
air entering your vehicle.
The air conditioning will not function if the fan is turned
off. If air conditioning is selected with fan off, the
indicator will ash three times and then turn off.
You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
The air conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
9(Fan):Turn the center knob on the control panel to
control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
3-21

The following are the available modes:
RFA 1 (default):This mode ashes the parking lamps
when you press the lock or unlock buttons on the
remote keyless entry transmitter.
RFA 2:This mode ashes the parking lamps and
sounds the horn when you press the lock button on the
remote keyless entry transmitter. This mode also
ashes the parking lamps when you press the unlock
button on the remote keyless entry transmitter.
RFA 3:This mode ashes the parking lamps and
sounds the horn when you press the lock or unlock
buttons on the remote keyless entry transmitter.
RFA 4:This mode disables remote keyless entry
feedback. There will be no feedback when you press
the lock or unlock buttons on the remote keyless
entry transmitter.DIC Warnings and Messages
Warning messages are displayed on the Driver
Information Center (DIC) to notify the driver that the
status of the vehicle has changed and that some action
may be needed by the driver to correct the condition.
More than one message may appear at one time. They
will appear one after the other. The messages are
displayed for four seconds each. Some messages may
not require immediate action but you should press
and release the trip odometer reset stem to
acknowledge that you received the message and clear it
from the display. Each message must be acknowledged
individually. Some messages cannot be cleared from
the display because they are more urgent. These
messages require action before they can be removed
from the DIC display. The following are the possible
messages that can be displayed and some information
about them.
AC (Air Conditioning) OFF
This message will be displayed when the engine coolant
temperature is too high and the air conditioning in
your vehicle needs to be turned off. SeeEngine
Overheating on page 5-27andClimate Control System
on page 3-21for more information. This message
will be displayed along with the ENG HOT message.
