NOTE:When programming a garage door opener, it is
advised to park outside the garage. It is also recom-
mended that a new battery be placed in the hand-held
transmitter of the device being programmed to
HomeLink for quicker training and accurate transmis-
sion of the radio-frequency signal.
The Electronic Vehicle Information Center (EVIC) fea-
tures a driver-interactive display which includes
HomeLink system messages. The EVIC is located on the
bottom of the tachometer.

156 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

All accessories connected to this outlet should be re-
moved or turned off when the vehicle is not in use to
protect the battery against discharge.CAUTION!
Electrical Outlet Use With Engine Off
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent engine
starting.
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the battery
even more quickly. Only use these intermittently and
with greater caution.
•After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.

HAZARD WARNING FLASHERS
Your vehicle’s hazard warning flasher is an emergency
warning system. When you activate it, all front and rear
directional signals will flash intermittently. 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 appropriate ac-
tion.
•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 conditioning system adds heat to
the engine cooling system and turning off the A/C

338 WHAT TO DO IN EMERGENCIES

JUMP STARTING
If the vehicle has a discharged battery, booster cables may
be used to obtain a start from a booster battery or the
battery in another vehicle. This type of start can be
dangerous if done improperly, so follow this procedure
carefully.WARNING!
Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or clothing.
Don’t lean over battery when attaching clamps or
allow the clamps to touch each other. If acid splashes
in eyes or on skin, flush contaminated area immedi-
ately with large quantities of water.
A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. Do
not use a 24 volt power source.
1. Remove all metal jewelry such as watch bands or
bracelets which might make an unintended electrical
contact.
346 WHAT TO DO IN EMERGENCIES

2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake on
both vehicles, place the transmission in P (Park), and turn
the ignition OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
