Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 280
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick, clean it with a paper
towel or cloth and then push it back in all
the way.
3. Pull out the dipstick again, keeping the tip
down, and check the level.

4. Open the hoods and locate the positive (+)
and negative (−) terminal locations on each
vehicle.
You will not need to access your battery for
jump starting. Your vehicle has a remote
positive (+) and a remote negative (−) jump
starting terminal.
The remote positive (+) terminal is located on
the engine compartment fuse block, under a
red cap. SeeEngine Compartment Overview
on page 280for more information on location.
The remote negative (−) ground terminal is a
bolt located under the metal frame that
supports the radiator. It is at the front of the
engine compartment, on the driver’s side
of the vehicle, and is marked with a label that
says GND (−).
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight if you need
more light.
Be sure the battery has enough water.
You do not need to add water to the
battery installed in your new vehicle. But
if a battery has ller caps, be sure the
right amount of uid is there. If it is low,
add water to take care of that rst. If you
do not, explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your retailer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 82.
Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow or ice, the wiper will stop
until the motor cools. If the overload is caused by
some electrical problem, have it xed.
Power Windows and Other
Power Options
Circuit breakers in the fuse panel protect the
power windows and other power accessories.
When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit
until the problem is xed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses.
This greatly reduces the chance of res caused by
electrical problems.
Look at the silver-colored band inside the fuse.
If the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new
one of the identical size and rating.
