WARNING!(Continued)
some collisions, air bags won’t deploy at all. Al-
ways wear your seat belts even though you have air
bags.
Advanced Front Air Bag Operation
Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts. Ad-
vanced Front Air Bags are not expected to reduce the risk
of injury in rear, side, or rollover collisions. The Ad-
vanced Front Air Bags will not deploy in all frontal
collisions, including some that may produce substantial
vehicle damage — for example, some pole collisions,
truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags.
The steering wheel hub trim cover and the upper right
side of the instrument panel separate and fold out of the
way as the air bags inflate to their full size. The Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The air bags then quickly deflate while
helping to restrain the driver and front passenger.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
•Do not overfill the coolant expansion bottle.
•Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
expansion bottle must also be protected against freez-
ing.
•If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
•Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.•Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
