190 Vehicle Care
Engine Overheating
The vehicle has an engine coolant
temperature warning light on the
instrument cluster to warn of engine
overheating. SeeEngine Coolant
Temperature Warning Light 096.
If the decision is made not to lift the
hood when this warning appears,
but instead get service help right
away, see Roadside Assistance
Program 0267.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
See if the engine cooling fan speed
increases when idle speed is
doubled by pushing the accelerator
pedal down. If it does not, the
vehicle needs service. Turn off the
engine.Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
If Steam is Coming from the
Engine Compartment
{Warning
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the (Continued)
Warning (Continued)
engine if it overheats, and get out
of the vehicle until the engine
is cool.
Overheated Engine
Protection
Operating Mode
The engine has an engine
protection mode to reduce the
chance of damage if the coolant
temperature goes too high (for
example, when climbing steep
grades in high temperature with
heavy loads, such as when towing a
trailer). When the engine
temperature reaches a certain level:
.The engine coolant temperature
warning light will illuminate.
. Engine power may be reduced.
. The air conditioning cooling
function may be automatically
turned OFF for a short time (the
blower will continue to operate).

Vehicle Care 191
Engine power and under certain
conditions, vehicle speed will
decrease. Vehicle speed can be
controlled with the accelerator
pedal, but the vehicle may not
accelerate at the desired speed.
The transmission will downshift or
upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and
engine coolant temperature is
reduced, vehicle speed can be
increased using the accelerator
pedal, and air conditioning cooling
function will automatically be turned
back ON.
If:1. The engine coolant temperature is not reduced.
2. The air conditioning cooling function does not turn
back ON.
3. The engine oil pressure low/ engine coolant temperature
high warning light illuminates,
this may indicate a malfunction.
Move the vehicle off the road in
a safe area and allow the engine to cool. If after checking
the oil and coolant, the oil
pressure low/engine coolant
temperature high warning light
remains on, do not continue to
drive. Call your dealer.
The malfunction indicator light may
also come on. If only it remains on,
you do not need to have the vehicle
towed, but have it inspected soon
by your dealer. For additional
information, see Malfunction
Indicator Lamp (Check Engine
Light) 091.
Washer Fluid
What to Use
When the vehicle needs windshield
washer fluid, read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall
below freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the reservoir is full. See Engine
Compartment Overview 0181 for
reservoir location.
Caution
. Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.

Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on both vehicles. Unplug unnecessary
accessories from the cigarette
lighter or the accessory power
outlet. Turn off the radio and all
lamps that are not needed.
This will avoid sparks and help
save both batteries. And it
could save the radio!
4. Open the hoods and locate the positive (+) and negative (−)
terminal locations of the other
vehicle.
{Warning
Using a match near a battery can
cause battery gas to explode.
People have been hurt doing this,
and some have been blinded.
Use a flashlight if you need more
light.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{Warning
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running. 5. Check that the jumper cables
do not have loose or missing
insulation. If they do, you could
get a shock. The vehicles
could be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) will
go to positive (+) or to a remote
positive (+) terminal if
equipped. Negative (−) will go
to an unpainted metal part or to
a remote negative (−) terminal
if equipped.
Do not connect positive (+) to
negative (−) or you will get a
short that would damage the
battery and possibly other parts
too. Do not connect the
negative (−) cable to the
negative (−) terminal on the
dead battery because this can
cause sparks.
6. Connect the red positive (+) cable to the positive (+)
terminal (1) of the dead battery.
Use a remote positive (+)
terminal if equipped. Do not let
the other end touch metal.
