system, then open the hood.

1.

Open the fuse box cover on your vehicle’s 
12-volt battery positive 

+

 terminal.

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.

u

If you use a booster battery, only use a 
12-volt booster battery.

u

When using an automotive battery 
charger, select a charging voltage lower 
than 15-volts. Check the charger manual 
for the proper setting.

Jump Starting Procedure

1

Jump Starting

Securely attach the jumper cable clips so that they do 
not come off when the engine vibrates. Also be 
careful not to tangle the jumper cables or allow the 
cable ends to touch each other while attaching or 
detaching the jumper cables.

Battery performance degrades in cold conditions and 
may prevent the engine from starting.

WARNING

A 12-volt 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 12-volt battery.

■

Next thing to do

1.

Check that the cooling fan is operating and 
turn the power system off once the high 
temperature indicator goes off.

u

If the cooling fan is not operating, 
immediately turn the power system off.

2.

Once the engine has cooled down, inspect 
the coolant level and check the cooling 
system components for leaks.

u

If the coolant level in the reserve tank is 
low, add coolant until it reaches the 

MAX

 mark.

u

If there is no coolant in the reserve tank, 
check that the radiator is cool. 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.

 P. 510

■

Last thing to do

Once the engine has cooled sufficiently, turn the power system on and check the 
high temperature indicator. If the high temperature indicator is off, resume driving. 
If it stays on, contact a dealer for repairs.

1

How to Handle Overheating

If the coolant is leaking, contact a dealer for repairs.

Use water as an emergency/temporary measure only. 
Have a dealer flush the system with proper antifreeze 
as soon as possible.

3

WARNING

Removing the radiator cap while the 
engine is hot can cause the coolant to spray 
out, seriously scalding you.

Always let the engine and radiator cool 
down before removing the radiator cap.
