HAZARD WARNING FLASHERS
Your vehicle's hazard warning flasher is an emer-
gency warning system. When you activate it, all
front and rear directional signals will flash intermit-
tently. Use it when your vehicle is disabled on or
near the road. It warns other drivers to steer clear
of you and your vehicle. This is an emergency
warning system, not to be used when the vehicle
is in motion.
To activate the warning flasher, push down on the
button on top of the steering column until it
latches. To turn the warning flasher off, push down
again to unlatch the button.
NOTE:
With extended use, the flasher may run down
your battery.

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce
the potential for overheating by taking the appro-
priate action.
• On the highways — Slow down.
• In city traffic — While stopped, put transmission
in N (Neutral), but do not increase engine idle
speed.
NOTE:
There are steps that you can take to slow down
an impending overheat condition. If your air
conditioner is on, turn it off. The air condition-
ing system adds heat to the engine cooling
system and turning off the A/C removes this
heat. You can also turn the Temperature Con-
trol to maximum heat, the Mode Control to
floor, and the Fan Control to High. This allows
the heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
CAUTION!
Driving with a hot 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 immedi-
ately, and call for service.

The three piece tool set, consisting of two snap-
