Full-Size Spare Tire

Your vehicle, when new, had a
fully-inflated spare tire. A spare tire
may lose air over time, so check its
inflation pressure regularly. See Tire
Pressure on page 10-56 and
Vehicle Load Limits on page 9-15
for information regarding proper tire
inflation and loading your vehicle.
For instruction on how to remove,
install or store a spare tire, see
Removing the Flat Tire and
Installing the Spare and Storing a
Flat or Spare Tire and Tools under
Tire Changing on page 10-73.
Notice: 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.
Your vehicle may have a different
size spare tire than the road tires
originally installed on your vehicle.
This spare tire was developed for
use on your vehicle, so it is all right
to drive on it. If your vehicle has
four-wheel drive and the different
size spare tire is installed, keep the
vehicle in two-wheel drive.
After installing the spare tire on your
vehicle, you should stop as soon as
possible and make sure the spare
tire is correctly inflated. Have the
damaged or flat road tire repaired or
replaced as soon as you can and
installed back onto your vehicle.
This way, the spare tire will be
available in case you need it again.
Do not mix tires and wheels of
different sizes, because they will not
fit. Keep your spare tire and its
wheel together. If your vehicle has a
spare tire that does not match your
vehicle's original road tires and
wheels in size and type, do not
include the spare in the tire rotation.

Jump Starting

For more information about the
vehicle battery, see Battery on
page 10-27.
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.
Warning
Batteries can hurt you. They can
be dangerous because:
They contain acid that can
burn you.
They contain gas that can
explode or ignite.
They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you.
