HANDLING THE UNEXPECTED
2. Connect the first jumper cable to your
vehicle's 12-volt battery (+) terminal.
3. Connect the other end of the first
jumper cable to the booster battery (+)
terminal. Use a 12-volt booster battery
only.
When using an automotive battery
charger, select a charging voltage lower
than 15 volts. Check the charger
manual for the proper setting.
4. Connect the second jumper cable to the booster battery (-) terminal.
5. Connect the other end of the second
jumper cable to the engine hanger as
shown. Do not connect this jumper
cable to any other part.
6. If your vehicle is connected to another
vehicle, start the assisting vehicle's
engine and increase its rpm slightly.
7. Attempt to start your vehicle's engine.
If it turns over slowly, make sure that
the jumper cables have good metal-to-
metal contact.
A battery can explode if you do not follow the correct procedure, seriously
injuring anyone nearby.
Keep all sparks, open flames, and smoking materials away from the battery.

Overheating
Signs your engine is overheating:
• The high temperature indicator comes on or the engine suddenly loses
power.
• Steam or spray comes out from under the hood.
First thing to do:
1. Immediately park the vehicle in a safe
place. Turn off all accessories and turn
on the hazard warning lights.
2. If no steam or spray is present: Keep
the vehicle running and open the hood
(See Under the Hood).
If steam or spray is present: Turn off
the power system and wait until it
subsides. Then, open the hood (See
Under the Hood).
3. Check that the cooling fan is operating and turn the power system off once
the high temperature indicator goes off. If the cooling fan is not operating,
immediately turn the power system off.
4. Once the engine has cooled down, inspect the coolant level and check the
cooling system components for leaks. If the coolant level in the reserve
tank is low, add coolant until it reaches the MAX mark. If there is no
coolant in the reserve tank, make sure the radiator is cool, then cover the
radiator cap with a heavy cloth and open the cap. If necessary, add coolant
up to the base of the filler neck, and put the cap back on.
