Engine Coolant Heater
The engine coolant heater, if available, can help in cold
weather conditions at or below 0°F (−18°C) for easier
starting and better fuel economy during engine warm-up.
Plug in the coolant heater at least four hours before
starting your vehicle. An internal thermostat in the
plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. For
the 2.2L and 2.4L engine, the electrical cord is
located on the passenger’s side of the vehicle near
the headlamp and the radiator.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
a dealer/retailer in the area where you will be parking
your vehicle. The dealer/retailer can give you the
best advice for that particular area.

If this light is on and not ashing, the TCS and
potentially the ESC system have been disabled. Check
your DIC messaging to determine which feature(s) is
no longer functioning and whether it is because of
the driver turning off the feature(s), or the system may
not be working properly and your vehicle requires
service. If the TCS is disabled, wheel spin will not be
limited. If the ESC system is disabled, the system
will not aid in maintaining vehicle directional control. In
either case, adjust your driving accordingly.
If the light is on and ashing, the TCS or the ESC
system is actively working. Check the DIC messaging
for details to determine which system is working. If
the LOW TRACTION message appears, the system is
limiting wheel spin. If the ESC ACTIVE message
appears, the system is aiding in maintaining vehicle
directional control.

Engine Coolant Temperature Gage
Your vehicle has an
engine coolant temperature
gage. With the ignition
turned to RUN, this gage
shows the engine
coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot. It means that your engine coolant has
overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-26.
Tire Pressure Light
Your vehicle may have a
tire pressure light.
This light comes on briey when the engine is started
and provides information about tire pressures and
the Tire Pressure Monitoring System.
When the Light is Solid
This indicates that one or more of your tires are
signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC), may accompany the light. SeeDIC
Warnings and Messages on page 3-48for more
information. Stop and check your tires as soon as it is
safe to do so. If underinated, inate to the proper
pressure. SeeTires on page 5-52for more information.

OIL LIFE
Press the information button until OIL LIFE displays.
The engine oil life system shows an estimate of the oil’s
remaining useful life. It shows 100% when the system
is reset after an oil change. It alerts you to change the oil
on a schedule consistent with your driving conditions.
In addition to the engine oil life system monitoring the oil
life, additional maintenance is recommended in the
Maintenance Schedule in this manual. SeeEngine Oil
on page 5-15andScheduled Maintenance on page 6-4.
Always reset the engine oil life system after an oil
change. See “How to Reset the Engine Oil Life System”
underEngine Oil Life System on page 5-19.
COOLANT
Press the information button until COOLANT displays.
This mode shows the temperature of the engine coolant
in either degrees Fahrenheit (°F) or degrees Celsius (°C).
Tire Pressure
If your vehicle has a Tire Pressure Monitor System
(TPMS), the pressure for each tire can be viewed in the
DIC. The tire pressure is shown in either pounds per
square inch (psi) or kilopascals (kPa). Press the
information button until LF ## PSI (kPa) ## RF displays
for the front tires. Press the information button again
until LR ## PSI (kPa) ## RR displays for the rear tires.If a low tire pressure condition is detected by the system

When towing a trailer, the arrows on your instrument
panel will ash 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
is important to check occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher
than normal engine and transmission temperatures
may result and damage your vehicle. Frequent
stops are very important to allow the engine and
transmission to cool.
When towing under severe conditions such as hot
ambient temperatures or steep grades, your vehicle may
experience more transmission shifting. A COOLING
MODE ON message may also appear in the DIC. This
alerts the driver that the shifting mode is in progress
and is aiding engine cooling. SeeDIC Warnings
and Messages on page 3-48DIC Warnings and
Messages for more information.
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to
reduce engine load. SeeEngine Overheating on
page 5-26.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) for an automatic transmission, or into
gear for a manual transmission. When parking
uphill, turn your wheels away from the curb. When
parking downhill, turn your wheels into the curb.
2. Have someone place chocks under the trailer
wheels.

Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-26.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
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 your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your 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:If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
5-24

Adding Coolant
If more coolant is needed, add the proper DEX-COOL®
coolant mixture at the coolant recovery tank, but
only when the engine is cool.
If the coolant recovery tank is completely empty, a
special ll procedure is necessary. SeeCooling System
on page 5-28for more information.
{CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the
radiator. Never turn the radiator pressure
cap — even a little — when the engine and
radiator are hot.
{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.
Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may occur.
Be sure the cap is properly and tightly secured.
SeeEngine Compartment Overview on page 5-12
for more information on location.
Engine Overheating
You will nd a coolant temperature warning light and a
coolant temperature gage on your vehicle’s instrument
panel. SeeEngine Coolant Temperature Warning
Light on page 3-38andEngine Coolant Temperature
Gage on page 3-39for more information.
5-26

If Steam Is Coming From Your Engine
{CAUTION:
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 your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned. Stop
your engine if it overheats, and get out of the
vehicle until the engine is cool.
Notice:If your engine catches re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
If No Steam Is Coming From
Your Engine
An engine coolant temperature warning can indicate a
serious problem. SeeEngine Coolant Temperature
Warning Light on page 3-38.
If you get an engine coolant temperature 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 engine coolant temperature 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. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
3. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.
