COMPACT SPARE TIRE
Although the compact spare was fully inflated when your vehicle was
new, it can lose air after a time. Check the inflation pressure regularly. It
should be
60 psi (420 Wa). The compact spare is made to go up to 3,000
miles (5000 km), so you can finish your trip and have your full-size tire
repaired or replaced where you want.
Of course, it’s best to replace your
spare with a full-size tire as soon as you can. Your spare will last longer
and be in good shape in case you need it again.

If you plan 6n driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t
work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
corrode, and your engine
oil can deteriorate quickly. Your vehicle’s
oxygen sensor
will be damaged. All of that means costly repairs that
wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell
us
where you’re going and give your Vehicle Identification Number (VIN).

It's a good idea to check your 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.
Turn
off the engine and give the oil a few minutes to drain back into the
oil pan. If you don't, the oil dipstick might not show the actual level.
