If the vehicle has four-wheel drive and a
different size spare tire is installed, do
not drive in four-wheel drive until the flat
tire is repaired and/or replaced. The
vehicle could be damaged and the repairs
would not be covered by the warranty.
Never use four-wheel drive when a
different size spare tire is installed on the
vehicle.

If the vehicle's battery (or batteries) has run
down, you may want to use another vehicle
and some jumper cables to start your
vehicle. Be sure to use the following steps
to do it safely.
If you do not follow these steps exactly,
some or all of these things can hurt you.
The vehicle may have a different size spare
tire than the road tires originally installed
on the vehicle. This spare tire was developed
for use on this vehicle, so it is all right to
drive on it. If the vehicle has four-wheel
drive and a different size spare tire is

Ignoring these steps could result in costly
damage to the vehicle that would not be

to start the vehicle by pushing or pulling
it will not work, and it could damage the
vehicle.

correct order, making sure that the cables
do not touch each other or other metal.

3. Get the vehicles close enough so the
jumper cables can reach, but be sure the
vehicles are not touching each other.
If they are, it could cause an unwanted
ground connection. You would not be
able to start your vehicle, and the bad
grounding could damage the electrical
systems.
The discharged battery positive (+) terminal
is under a cover. Open the cover to expose
the terminal.
1. Check the other vehicle. It must have a
12-volt battery with a negative ground
system.
To avoid the possibility of the vehicles
rolling, set the parking brake firmly on
both vehicles involved in the jump start
procedure. Put the automatic

unplug all accessories on either vehicle
when jump starting.
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 flashlight if you need
more light.
Do not connect positive (+) to negative
(−) or you will get a short that would
damage the battery and maybe other
parts too. And do not connect the
negative (−) cable to the negative (−)
terminal on the dead battery because
this can cause sparks.
4. Turn the ignition off on both vehicles.
Unplug unnecessary accessories plugged
into the accessory power outlets. Turn
off the radio and all the lamps that are
not needed. This will avoid sparks and
help save both batteries. And it could
save the radio!
Battery fluid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on
your skin, flush the place with water and
get medical help immediately.
7. Connect one end of the red positive (+)
cable to the discharged battery
positive (+) terminal.
5. Open the hood on the other vehicle and
locate the positive (+) and negative (−)
terminal locations on that vehicle.
8. Do not let the other end touch metal.
Connect the other end of the positive (+)
cable to the good battery positive (+)
terminal. Use a remote positive (+)
terminal if the vehicle has one.
Warning
{
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
Warning
{
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.
9. Connect one end of the black negative
(−) cable to the good battery negative
(−) terminal. Use a remote negative (−)
terminal if the vehicle has one.
6. Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock. The vehicles
could be damaged too.
Do not let the other end touch anything
until the next step.
Before you connect the cables, here are
some basic things you should know.
