If No Steam Is Coming From Your
Engine
If you get an engine 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.
Stop after high-speed driving.
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. If you have an air conditioner and it is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.
3. Try to minimize engine load. If you are in a traffic
jam, shift to NEUTRAL (N); otherwise, shift to the
highest gear possible while driving.If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about ten minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. If the warning
continues, 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.

Cooling System
When you decide it is safe to lift the hood, here is what
you will see:
A. Electric Engine Fan (Not Shown)
B. Coolant Surge Tank
C. Pressure Cap{CAUTION:
An electric engine cooling fan under the hood
can start up even when the engine is not
running and can injure you. Keep hands,
clothing, and tools away from any underhood
electric fan.
If the coolant inside the coolant surge tank is boiling,
do not do anything else until it cools down. The vehicle
should be parked on a level surface.
5-25
ProCarManuals.com

The coolant level should be between the MIN and MAX
lines. If it is not, you may have a leak at the radiator
hoses, heater hoses, radiator, water pump, or
somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them.
If you do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine re, and you could be
burned. Get any leak xed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan is running. If the
engine is overheating, the fan should be running. If it is
not, your vehicle needs service. Turn off the engine.
Notice:Engine damage from running the engine
without coolant is not covered by the warranty.Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by the warranty. Always
use DEX-COOL
®(silicate-free) coolant in the vehicle.
How to Add Coolant to the Coolant
Surge Tank
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
If you have not found a problem yet, check to see if
coolant is visible in the surge tank. If coolant is visible
but the coolant level is not at between the MIN and MAX
lines, add a 50/50 mixture of clean, drinkable water
and DEX-COOL
®coolant at the coolant surge tank,
but be sure the cooling system, including the coolant
surge tank pressure cap, is cool before you do it.
SeeEngine Coolant on page 5-20for more information.

{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 pressure cap.
{CAUTION:
Adding only plain water to the cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the
proper coolant mixture will. The vehicle’s
coolant warning system is set for the proper
coolant mixture. With plain water or the wrong
mixture, the engine could get too hot but you
would not get the overheat warning. The engine
could catch re and you or others could be
burned. Use a 50/50 mixture of clean, drinkable
water and DEX-COOL
®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 mixture.

{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. Do not spill coolant on a hot engine.
1. You can remove the
coolant surge tank
pressure cap when
the cooling system,
including the coolant
surge tank pressure
cap and upper radiator
hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
about one-quarter of a turn. If you hear a hiss,
wait for that to stop. This will allow any pressure
still left to be vented out the discharge hose.
2. Then keep turning the pressure cap slowly, and
remove it.3. Fill the coolant surge tank with the proper
DEX-COOL
®coolant mixture, to between the
MIN and MAX lines.
4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper DEX-COOL
®coolant mixture
to the coolant surge tank until the level reaches
between the MIN and MAX lines.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight.

Check the level in the surge tank when the cooling
system has cooled down. If the coolant is not at the
proper level, repeat Steps 1 through 3 and reinstall the
pressure cap. If the coolant still is not at the proper level
when the system cools down again, see your retailer.
Windshield Washer Fluid
What to Use
When you need windshield or rear window washer uid,
be sure to read the manufacturer’s instructions before
use. If you will be operating your vehicle in an area
where the temperature may fall below freezing, use a
uid that has sufficient protection against freezing.
Adding Windshield Washer Fluid
Open the cap with the
washer symbol on it.
Add washer uid until the
tank is full. SeeEngine
Compartment Overview
on page 5-12for reservoir
location.Notice:
When using concentrated washer uid, follow
the manufacturer’s instructions for adding
water.
Do not mix water with ready-to-use washer uid.
Water can cause the solution to freeze and
damage your washer uid tank and other parts
of the washer system. Also, water does not
clean as well as washer uid.
Fill the washer uid tank only three-quarters
full when it is very cold. This allows for uid
expansion if freezing occurs, which could
damage the tank if it is completely full.
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage the vehicle’s
windshield washer system and paint.

Brakes
Brake Fluid
The brake master cylinder
reservoir is lled with
DOT-3 brake uid. See
Engine Compartment
Overview on page 5-12for
the location of the reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down. The rst is that the brake
uid goes down to an acceptable level during normal
brake lining wear. When new linings are put in, the uid
level goes back up. The other reason is that uid is
leaking out of the brake hydraulic system. If it is, have
the brake hydraulic system xed, since a leak means
that sooner or later the brakes will not work well.It is not a good idea to top off the brake uid. Adding
brake uid will not correct a leak. If uid is added when
the linings are worn, there will be too much uid when
new brake linings are installed. Add or remove brake
uid, as necessary, only when work is done on the brake
hydraulic system.
{CAUTION:
If your vehicle has too much brake uid, it can
spill on the engine. The uid will burn if the
engine is hot enough. You or others could be
burned, and your vehicle could be damaged.
Add brake uid only when work is done on the
brake hydraulic system.
When the brake uid falls to a low level, the brake
warning light comes on. SeeBrake System Warning
Light on page 3-32.
5-30
ProCarManuals.com

What to Add
When you need brake uid, use only DOT-3 brake uid.
Use new brake uid from a sealed container only.
SeeRecommended Fluids and Lubricants on page 6-12.
Always clean the brake uid reservoir cap and the
area around the cap before removing it. This helps keep
dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake
hydraulic system, the brakes might not work
well. This could cause a crash. Always use the
proper brake uid.Notice:
Using the wrong uid can badly damage brake
hydraulic system parts. For example, just a
few drops of mineral-based oil, such as engine
oil, in the brake hydraulic system can damage
brake hydraulic system parts so badly that they
will have to be replaced. Do not let someone
put in the wrong kind of uid.
If you spill brake uid on your vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on your
vehicle. If you do, wash it off immediately.
SeeWashing Your Vehicle on page 5-82.

12-Volt Battery
When it is time for a new standard 12-volt battery, see
your dealer/retailer for one that has the replacement
number shown on the original battery’s label.
36-Volt Battery System
If you need a new 36-volt hybrid battery system, see
your dealer/retailer.
Vehicle Storage
Infrequent Usage: If you drive your vehicle infrequently,
remove the 12-volt battery black, negative (−) cable from
the battery, the one that is exposed. This will help keep
the battery from running down.
Extended Storage: For extended storage of your
vehicle, remove the 12-volt battery black, negative (−)
cable from the battery or use a battery trickle charger.
This will help maintain the charge of the battery over an
extended period of time.
Remember to reconnect the battery when you are ready
to drive your vehicle.
Notice:The 36-volt hybrid battery system should
be serviced only by a qualied facility to avoid
battery system damage. See your dealer/retailer
if service is needed.Notice:If the vehicle is not driven for over
two months, the 36-volt hybrid battery can be
permanently damaged.
The 36-volt battery is located behind the rear seat,
under the cargo oor. If the vehicle is stored for
an extended period of time, drive the vehicle every
two months for about half an hour to keep the 36-volt
hybrid battery charged and in good working condition.
Jump Starting
Your hybrid vehicle has a standard 12-volt battery in the
engine compartment, and a 36-volt battery under the
rear load oor.
{CAUTION:
Personal injury or damage to the vehicle can
result if you try jump starting or using a battery
charger on the 36-volt battery. Use only the
12-volt battery for jump starting and charging.
If your vehicle’s standard 12-volt battery has run down,
you may want to use another vehicle and some jumper
cables to start your vehicle. Be sure to use the following
steps to do it safely.

4. Open each vehicle’s hood and locate the
positive (+) and negative (−) terminal locations of the
other vehicle. Your vehicle has a remote positive (+)
12-volt jump starting terminal and a remote
negative (−) jump starting terminal. You should
always use these remote terminals instead of the
terminals on the battery. The remote positive (+)
terminal is located inside the junction box located
above the engine cover. To access the remote
positive (+) terminal, unlatch the box cover.
5. The remote negative (−) terminal is a stud on
the driver side near the underhood fuse block.
{CAUTION:
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
ashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the battery installed
in your new vehicle. But if a battery has ller
caps, be sure the right amount of uid is there.
If it is low, add water to take care of that rst.
If you do not, explosive gas could be present.
Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ush the place
with water and get medical help immediately.
