Downloaded from www.Manualslib.com manuals search engine When towing a trailer, the arrows on your instrument
panel
will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may
think drivers behind you
are seeing your signal when they are not. It's important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear byfilw you start
down
a long or steep downgrade. If you don't shift
down. you might have to use your brakes
so much that
they would get hot and no longer work well.
On
a long uphill grade. shift down and reduce your
speed
to around 45 mph (70 km/h) to reduce the
possibility of engine and transmission overheating.
if
you have an automatic transmission. you should use
DRIVE (D) when towing a trailer. Operating your
vehicle in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the life
of your
transmission. Or.
if you have a manual transmission. it's
better not to use
FIFTH (5 j gear. just drive in
FOURTH (4) gear (or. as you need to. a lower gear). When
towing
at high altitude on steep uphill grades.
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes.
If you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating.
To avoid this. let the
engine
run while parked (preferably on level ground)
with the automatic transmission in PARK (P) (or the
rnanual transmission out of gear and the parking brake
applied) for a few minutes before turning the engine off.
If you do get the overheat warning, see "Engine
Overheating"
in the Index.

If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
0 Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades” in the Index.
If you get the overheat warning with no sign of steam,
try
this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window
as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@) or
DRIVE (D) for automatic transmissions. If
you
no longer have the overheat warning, you
can drive. Just
to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If
the warning continues, pull over, stop, and park your
vehicle right away.
If there’s
still no sign of steam, push the accelerator until
the engine speed
is about twice as fast as normal idle
speed. Bring the engine speed back to normal idle speed
after two or three minutes. Now
see if the warning stops.
But then, if you still have the warning,
turn ofthe
engine and get everyone out of the vehicle until it
cools down.
You may decide not to lift the hood but
to get service
help right away.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Recovery Tank
If you haven‘t found a problem yet, but the coolant level
isn‘t at the ADD mark, add a SO/SO mixture of clenrz
wter (preferably distilled) and DEX-COOL”
(silicate-free) antifreeze at the coolant recovery tank.
(See ”Engine Coolant”
in the Index for more
information.)
A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix
will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water
or the wrong mix, your engine could
get too hot but >‘ou wouldn’t get the overheat
warning. k‘our
engine could catch fire and you or
others
could he hurned. Use a 50/50 mix of clean
water and DKX-CWOL” coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant
mix.

I A CAUTION:
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.
When the coolant in the coolant recovery tank is at the
ADD mark, 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 radiator, but be sure the cooling system is
cool before you do it.
