2. Insert the tip of the emergency key or a #2 flat blade
screwdriver into the slot and gently pry the two halves of
the RKE transmitter apart. Make sure not to damage the
seal during removal.
3. Remove and replace the battery. When replacing the
battery, match the + sign on the battery to the + sign on
the inside of the battery clip, located on the 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.

26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
However, wide-open throttle acceleration in low gear can
be detrimental and should be avoided.
The engine oil, transmission fluid, and axle lubricant
installed at the factory is high-quality and energy-
conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under
which vehicle operations will occur. For the recom-
mended viscosity and quality grades, refer to “Mainte-
nance Procedures” in “Maintaining Your Vehicle”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE:A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. Thisshould be considered a normal part of the break-in and
not interpreted as an indication of difficulty.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
•It 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.

damaged, have a competent mechanic inspect the com-
plete exhaust system 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 as required.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
Air Bag Warning Light
The light should come on and remain on for four to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit the footwell of your
vehicle. Use only floor mats that leave the pedal area
unobstructed and that are firmly secured so that they
cannot slip out of position and interfere with the pedals
or impair safe operation of your vehicle in other ways.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 97

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. 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 vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealership for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer-
ship for service if your vehicle overheats. If you
decide to look under the hood yourself, see “Main-
taining Your Vehicle”. Follow the warnings under the
Cooling System Pressure Cap paragraph.

(ACC)” in “Understanding The Features Of Your
Vehicle” (if equipped).
•Brake — If the ACC system predicts that its maximum
braking level is not sufficient to maintain the set
distance, this message will flash and a chime will
sound while ACC continues to apply its maximum
braking capacity. When this occurs, you should imme-
diately apply the brakes as needed to maintain a safe
distance from the vehicle ahead. Refer to “Adaptive
Cruise Control (ACC)” in “Understanding The Fea-
tures Of Your Vehicle” (if equipped).
•Clean Radar Sensor in the Front of Vehicle — If the
ACC system deactivates due to performance limiting
conditions. Refer to “Adaptive Cruise Control (ACC)”
in “Understanding The Features Of Your Vehicle” (if
equipped).
•ACC/FCW Unavailable Vehicle System Error — If the
ACC system turns off due to a temporary malfunction
that limits functionality. Refer to “Adaptive Cruise
Control (ACC)” in “Understanding The Features Of
Your Vehicle” (if equipped).
•ACC/FCW Unavailable Service Radar Sensor — If the
ACC system turns off due to an internal system fault
that requires service from an authorized dealer. Refer
