IN CASE OF EMERGENCY

 

6. Once the engine is started, follow the 

disconnecting procedure below.

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 negative 

(-) 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 positive 

(+) 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.

REFUELING IN EMERGENCY – IF EQUIPPED 

The vehicle may be equipped with a refueling 

funnel  

Ú

page 390. Vehicles with diesel 

engines will have a cap to remove to begin the 

refueling process. If refueling is necessary, 

while using an approved gas can, insert the 

refueling funnel into the filler neck opening. 

Take care to open both flappers with the funnel 

to avoid spills.

Diesel Fuel Cap

NOTE:

In certain cold conditions, ice may prevent the 

fuel door from opening. If this occurs, lightly 

push on the fuel door to break the ice buildup 

and re-release the fuel door using the inside 

release button. Do not pry on the door.

Refueling Funnel

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.

CAUTION!

Accessories plugged into the vehicle power 

outlets draw power from the vehicle’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 discharge sufficiently to degrade 

battery life and/or prevent the engine from 

starting.
