You can be burned if you spill coolant on hot
engine parts. Coolant
contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don’t spill coolant on -a hot engine.

ADD, start your vehicle.
If the overheat warning continues, there’s one more
thing you can try. You can add the. proper coolant .mix
directly to the radi,ator, but be sure the cooling system is
cool before you do it.

It’s unusual for a tire to “blow out’? while you’re driving,
especially if you- maintain your tires properly. If-air goes
out of.a..tire, it3 much more likely to le:& out sbwly.
But if you should. ever have a “blowoilt,” hme are a few
tips about what to expec~ -and what to do:

Downloaded from www.Manualslib.com manuals search engine If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over
you or other
people.
You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
I. Set the parking brake firmly.
2. Put an automatic transmission shift
lever in
PARK (PI or shift a manual
transmission to FIRST (1) or
REVERSE (R).
CAUTION: (Continued)
3. If you have a four-wheel-drive vehicle
with
a manual transfer case shift lever,
be sure the transfer case is in
a drive
gear
-- not in NEUTRAL (N).
4. Turn off the engine.
5. Put the wheel blocks at the front and
rear
of the tire farthest away from the
one being changed. That would be the
tire on the other side
of the vehicle, at
the opposite end.
