Full-Size Spare Tire
If this vehicle came with a full-sizespare tire, it was fully inflated whennew, however, it can lose air overtime. Check the inflation pressureregularly. SeeTire Pressure0260andVehicle Load Limits0171.Forinstructions on how to remove,install, or store a spare tire, seeTireChanging0274.
After installing the spare tire on thevehicle, stop as soon as possibleand check that the spare is correctlyinflated. The spare tire is made toperform well at speeds up to11 2 k m / h ( 7 0 m p h ) a t t h erecommended inflation pressure, soyou can finish your trip.
Have the damaged or flat road tirerepaired or replaced back onto thevehicle, as soon as possible, so thespare tire will be available in case itis needed again.
Do not mix tires and wheels ofdifferent sizes, because they will notfit. Keep the spare tire and its wheeltogether.

Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
1. Check the other vehicle.It must have a 12-volt batterywith a negative ground system.
Caution
If the other vehicle does not have
a12-voltsystemwithanegative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Get the vehicles close enoughso the jumper cables canreach, but be sure the vehiclesare not touching each other.If they are, it could cause a
ground connection you do notwant. You would not be able tostart your vehicle, and the badgrounding could damage theelectrical systems.
To a v o i d t h e p o s s i b i l i t y o f t h evehicles rolling, set the parkingbrake firmly on both vehiclesinvolved in the jump startprocedure. Put an automatictransmission in P (Park) or amanual transmission in Neutralbefore setting the parkingbrake.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on bothvehicles. Unplug unnecessaryaccessories plugged into the
cigarette lighter or theaccessory power outlet. Turnoff the radio and all lamps thatare not needed. This will avoidsparks and help save bothbatteries. And it could save theradio!
4. Open the hoods and locate thepositive (+) and negative (✓)terminal locations of the othervehicle.
On your van, use the unpaintedradio antenna bracket as aremote negative (✓)terminal.
{Warning
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.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
