5. Start the engine in the vehicle that has the

booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.

CAUTION!

Do not run the booster vehicle engine
above 2,000 rpm since it provides no
charging benefit, wastes fuel, and can
damage booster vehicle engine.

6. Once the engine is started, remove the

jumper cables in the reverse sequence:

Disconnecting The Jumper Cables

1. Disconnect the negative

(-)

end of the

jumper cable from the engine ground of
the vehicle with the discharged battery.

2. Disconnect the opposite end of the nega-

tive

(-)

jumper cable from the negative

(-)

post of the booster battery.

3. Disconnect the positive

(+)

end of the

jumper cable from the positive

(+)

post of

the booster battery.

4. Disconnect the opposite end of the posi-

tive

(+)

jumper cable from the remote

positive

(+)

post of the discharged

vehicle.

5. Reinstall the protective cover over the

remote positive

(+)

post of the discharged

vehicle.

If frequent jump starting is required to start
your vehicle you should have the battery and
charging system tested at an authorized
dealer.

CAUTION!

Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular

devices,

etc.).

Eventually,

if

plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.

IF YOUR ENGINE
OVERHEATS

In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.

• On the highways — slow down.

• In city traffic — while stopped, shift trans-

mission into NEUTRAL, but do not increase
engine idle speed.

CAUTION!

Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (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 HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
