Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to
have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
hooked up, the trailer lights will also flash,
telling other drivers you’re about to
turn,
change lanes or stop.
When towing a trailer, the green 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
before 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
are towing a trailer and you
have an automatic transmission with
Overdrive, you may prefer to drive
in D
instead of Overdrive (or, as you need to,
a lower gear). Or, if you have a manual
transmission
with fifth (or sixth) gear
and you are towing a trailer, it’s better
not to use
fifth (or sixth) gear. Just drive
in fourth gear (fifth gear
if you have
a six-speed manual transmission)
(or, as you need to, a lower gear.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but
the coolant level isn’t
at or above FULL
COLD,
add a 50/50 mixture of clean
water
(preferably distilled) and a proper
antifreeze at the coolant recovery tank.
(See “Engine Coolant”
in the Index for
more information about the proper
coolant
mix.)
A Adding only plain water to
L your cooling system can be
dangerous. Plain water, or some
I
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 you wouldn’t get the overheat
warning. Your engine could catch
fire and you or others could
be
burned. Use a 50/50 mix of clean
water
and a proper antifreeze.

Adding Coolant
To Check Coolant: When your engine is
cold, check the dipstick on the cap of the
coolant recovery tank. The coolant level
should be at
FULL COLD, or a little
higher. When your engine is warm, the
level on the dipstick should be up to
FULL HOT, or a little higher.
If you have the 5.7L LTl (Code P) engine
and this light comes on,
it means you’re
low on engine coolant.
To Add Coolant to the Recovery Tank:
If you need more coolant, add the proper
mix
at the coolant recovery tank, but
only when your engine
is cool. If the tank
is very low or empty, also add coolant to
the radiator. See “Engine Overheating” in
the Index.

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.
Radiator Pressure Cap (All Engines)
~ NOTICE:
Your radiator cap is a 18 psi
(124 kPa) pressure-type cap and
must be tightly installed to prevent
coolant loss and possible engine
damage from overheating. Be sure
