Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine
is started.
If the light stays on, turn the ignition to LOCK/OFF or if
the light comes on, stop as soon as possible and
turn the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on again
while driving, the vehicle needs service. See your
dealer/retailer. If the regular brake system warning light
is not on, the brakes will still work, but the antilock
brakes will not work. If the regular brake system warning
light is also on, the antilock brakes will not work
and there is a problem with the regular brakes.
SeeBrake System Warning Light on page 3-28.
The ABS warning light will come on briey when the
ignition is turned to ON/RUN. This is normal. If the light
does not come on then, have it xed so it will be
ready to warn if there is a problem.
Hold Mode Light
If the vehicle has this
feature, this light comes on
when the hold mode is
active.
If the HOLD mode light ashes, have the vehicle checked.
See “Hold Mode” underAutomatic Transmission
Operation on page 2-20for more information.
Engine Coolant Temperature Gage
The vehicle may have an engine coolant temperature
gage. With the ignition turned to ON/RUN, this gage
shows the engine coolant temperature.
United StatesCanada
3-30

If the gage pointer moves into the red area, the engine
is too hot. It means that the engine coolant has
overheated.
If the vehicle has been operating under normal driving
conditions, pull off the road, stop the vehicle and turn off
the engine as soon as possible.
SeeEngine Overheating on page 5-28.
Tire Pressure Light
For vehicles with the tire
pressure light, it comes on
briey when the engine
is started.
It provides information about tire pressures and the
Tire Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires are
signicantly underinated.
Stop and check the tires as soon as it is safe to do,
and inate them to the proper pressure. SeeTires on
page 5-50for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the
Tire Pressure Monitor System. The light ashes
for about a minute and then stays on steady for the
remainder of the ignition cycle. This sequence will repeat
with every ignition cycle. SeeTire Pressure Monitor
System on page 5-58for more information.

Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it is in
the vehicle. Static electricity discharge from the
container can ignite the fuel vapor. You can be
badly burned and the vehicle damaged if this
occurs. To help avoid injury to you and others:
Dispense fuel only into approved containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed,
or on any surface other than the ground.
Bring the ll nozzle in contact with the inside
of the ll opening before operating the nozzle.
Contact should be maintained until the lling
is complete.
Do not smoke while pumping fuel.
Do not use a cellular phone while
pumping fuel.
Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing, and tools away from any
underhood electric fan.
{CAUTION:
Things that burn can get on hot engine parts and
start a re. These include liquids like fuel, oil,
coolant, brake uid, windshield washer and other
uids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things
that will burn onto a hot engine.

If the engine oil pressure
light comes on, check the
engine oil level right away.
The oil pressure light is on the instrument panel cluster.
SeeOil Pressure Light on page 3-34. Check the engine
oil level regularly; this is an added reminder.
5-13

How to Check and Add Fluid
The reservoir is located near the back of the engine
compartment on the driver side of the vehicle.
SeeEngine Compartment Overview on page 5-12
for more information on location.
To check the uid level, look on the side of the reservoir.
If the uid reaches the MAX (A) mark on the reservoir,
the uid level is correct. If the uid does not reach
the MIN (B) mark on the reservoir, then uid needs
to be added.
Cooling System
The cooling system allows the engine to maintain the
correct working temperature.

{CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
{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.Notice:Using coolant other than DEX-COOL
®can
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs would
not be covered by the vehicle warranty. Always use
DEX-COOL
®(silicate-free) coolant in the vehicle.
Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a problem
with engine overheating, seeEngine Overheating on
page 5-28.
5-23

What to Use
{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.
Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing
else needs to be added. This mixture:
Gives freezing protection down to−34°F (−37°C),
outside temperature.
Gives boiling protection up to 265°F (129°C),
engine temperature.
Protects against rust and corrosion.
Will not damage aluminum parts.
Helps keep the proper engine temperature.Notice:If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 6-12for more information.
Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
Check to see if coolant is visible in the coolant surge
tank. If the coolant inside the coolant surge tank is boiling,
do not do anything else until it cools down. If coolant is
visible but the coolant level is not between the Minimum
and Maximum marks, add a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant at the coolant
surge tank, but be sure the cooling system is cool before
this is done. SeeEngine Coolant on page 5-23for more
information.
