between hard stops. Your brakes will wear out much faster

A CAUTION:
I
“Riding” your brakes can cause them to overheat to the point
that they won’t work well.
You might not be able to stop your
vehicle in time to avoid an accident.
If you “ride” your brakes,
they
will get so hot they will require a lot of pedal force to slc
you down. Avoid “riding” the brakes.

You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need
to go much farther
beyond the passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left.
To move the trailer to
the right, move your hand to
the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than normal. Do
this so your trailer won’t strike soft shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden maneuvers. Signal well
in advance.
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) or less to reduce the possibility of engine and transaxle
overheating.

NOTICh:
If your engine catches fire because you keep drivmg with no
coolant, your vehicle can be badly damaged. The costly repairs
lwuld not be covered
by your warranty.

If No Steam Is Coming From Your Engine:
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:
e Climb a long hill on a hot day.
Stop after high speed driving.
e Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign
of steam, try this for a
minute or
so:
1. Turn off your air conditioner.

Downloaded from www.Manualslib.com manuals search engine 2. Turn on your heater to full hot at the highest fan speed and open the
window as necessary.
3. Try to keep your engine under load (in a drive gear where the engine
runs slower).
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower
for about ten 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, you can idle the engine for two or three
minutes while you’re parked, to see
if the warning stops. But then, if you
still have the warning, TURN
OFF THE 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.

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

mix.)

You
can add the proper coolant mix directly to the radiator, but be sure

“FULL

and a proper antifreeze at the coolant recovery tank. (See “Engine

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.
Should a low coolant condition
exist, an overheat protection “Limp
Home” feature of the
4.6L Northstar allows alternate firing groups of
four cylinders for a predetermined number of cycles to prevent engine
damage, enabling your vehicle
to be driven to the nearest service center.

A CAUTION
Steam and scalding liquids from a hot cooling system can blow
out and burn you badly. They are under pressure, and
if you
turn the coolant surge tank pressure cap
-- even a little -- they
can come out at high speed. Never turn the cap when the cooling
system, including the coolant surge tank pressure
cap, is hot.
Wait
for the cooling system and coolant surge tank pressure cap
to
cool if you ever have to turn the pre;.=we cap.

Downloaded from www.Manualslib.com manuals search engine If you let your tires spin at high speed, they can explode and you
or others could be injured. And, the transaxle or other parts of
the vehicle can overheat. That could cause an engine
compartment fire or other damage. When you’re stuck, spin the
wheels as little as possible. Don’t spin the wheels above
35 mph
(55 km/h) as shown on the speedometer.
-3pannmg your
H ; can destroy parts of your v( cle as well
I as the tires. If you spin the wheels too fast while shifting your
transaxle back and forth, you can destroy your transarj
.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will clear the area
around your front wheels. Then shift back and forth between
“R’
(Reverse) and a forward gear, spinning the wheels as little as possible.
Release the accelerator pedal while you shift, and press lightly on the
accelerator pedal when the transaxle is in gear.
If that doesn’t get you out
after
a few tries, you may need to be towed out. If you do need to be
towed out, see “Towing
Your Vehicle” in the Index.
