inside of the battery clip, located on back cover. Avoid
touching the new battery with your fingers. Skin oils may
cause battery deterioration. If you touch a battery, clean it
with rubbing alcohol.
3. To reassemble the transmitter case, snap the two
halves of the case together. Make sure there is an even
ªgapº between the two halves. If equipped, install and
tighten the screw until snug. Test RKE transmitter opera-
tion.REMOTE STARTING SYSTEM Ð IF EQUIPPED

²The lap portion should be low on the hips and as snug
as possible.
²Check belt fit periodically. A child's squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
miles (500 km). After the initial 60 mi (100 km), speeds up
to 50 or 55 mph (80 or 90 km/h) are desirable. While
cruising, brief full-throttle acceleration, within the limits
of local traffic laws, contributes to a good break-in.
Avoid wide-open throttle acceleration in low gear.
The engine oil installed in the engine at the factory is a
high-quality, energy-conserving type lubricant. Oil
changes should be consistent with the anticipated cli-
matic conditions under which vehicle operation will
occur. The recommended viscosity and quality grades are
discussed in Section 7 under Maintenance Procedures,
Engine Oil.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This is a nor-
mal part of the break-in and is not an indication of
difficulty.
CAUTION!
²During the first 500 mi (805 km) your new vehicle
is driven, do not tow a trailer. Doing so may
damage your axles, driveline and vehicle.
²Limit your speed to 50 mph (80 km/h) during the
first 500 mi (805 km) of towing.
SAFETY TIPS
Transporting Passengers
This vehicle is designed to carry passengers in the cab
only. For safety reasons, NEVER TRANSPORT PASSEN-
GERS IN THE CARGO AREA.
WARNING!
²It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seri-
ously injured or killed.
²Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat
belts.
²Be sure everyone in your vehicle is in a seat and
using a seat belt properly.

Exhaust Gas
WARNING!
Exhaust gases contain carbon monoxide, a potentially
toxic gas that, by itself, is colorless and odorless. To
avoid inhaling these gases, the following precautions
should be observed:
²Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
²If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into
the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
²The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system,
exhaust fumes detected inside the vehicle, or damage to
the underside or rear of the vehicle. Have a competent
authorized mechanic inspect the complete exhaust sys-
tem and adjacent body areas for broken, damaged,
deteriorated or mispositioned parts. Open seams or loose
connections could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect the exhaust
system each time the vehicle is raised for lubrication or
oil change. Replace or adjust as required.
78 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Lights
Check the operation of all exterior lights. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, water, oil, or other fluid leaks. Also, if fuel fumes are
detected, the cause should be located and corrected.

INSTRUMENT CLUSTER DESCRIPTION
1. Check Gauges ± Premium Cluster Only
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gauges indicate a reading either too high or too low.
Examine the gauges carefully, and follow the instructions
contained below for each indicated problem.
NOTE:When the ignition switch is turned to OFF, the
Fuel Gauge, Voltmeter, Oil Pressure and Engine Coolant
Temperature gauges may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. Ifthe pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gaugesº indicator will illuminate
and a single chime will sound. The ªCheck Gaugesº
indicator may also illuminate prior to the voltage gauge
moving out of normal range. In either case, see you local
authorized Dealer for system service.
3. Turn Signal Indicators
Lights in instrument cluster flash when outside turn
signals are operating.
4. Tachometer
The Tachometer indicates engine speed in revolutions per
minute.

CAUTION!
Do not operate the engine with the tachometer
pointer at high rpm for extended periods. Engine
damage may occur.
5. Airbag Indicator Light
The indicator lights and remains lit for six to eight
seconds when the ignition is first turned ON. If the light
stays on, flickers or comes on while driving, have the
airbag system checked by an authorized dealer.
6. High Beam Indicator
This indicator shows that headlights are on high
beam.
7. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for five to eight seconds as a bulbcheck. During the bulb check, if the driver's seat belt is

when driving, if the driver's seat belt remains unbuckled,
the Seat Belt Warning Light will flash or remain on
continuously. Refer to9Enhanced Driver Seat Belt Re-
minder System (BeltAlertt)9in the Occupant Restraints
section for more information.(See page 46 for more
information.)
8. Speedometer
The Speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (mph/kph).
9. Oil Pressure Gauge Ð Premium Cluster Only
The pointer should always indicate some oil pres-
sure when the engine is running. A continuous
high or low reading, under normal driving conditions,
may indicate a lubrication system malfunction. Immedi-
ate service should be obtained from an authorized dealer.
