2-10 Keys, Doors, and Windows
A maximum of two remote starts,
or a remote start with an extension,
are allowed between ignition cycles.
The vehicle's ignition must be
changed to ON/RUN/START and
then back to OFF before the remote
start procedure can be used again.
Canceling Remote Start
To cancel a remote start, do any of
the following:
.Aim the RKE transmitter at the
vehicle and press and hold
B
until the parking lamps turn off.
.Turn on the hazard warning
flashers.
.Press the POWERObutton on
the center stack, with the brake
pedal applied, then press the
POWER
Obutton again to turn
the vehicle off.
Conditions in Which Remote
Start May Not Work
Conditions in which a remote start
may not occur include:
.An open hood.
.Vehicle propulsion system fault
conditions, including an
emission control system
malfunction.
.High voltage battery fault
conditions.
A second remote start or extension
will not occur if the fuel level is low.
During a remote start, conditions in
which a remote start may be
canceled include:
.Vehicle propulsion system or
high voltage battery fault
conditions.
.Low engine oil pressure.
.Engine coolant temperature that
is too high.
Door Locks
{Warning
Unlocked doors can be
dangerous.
.Passengers, especially
children, can easily open the
doors and fall out of a moving
vehicle. The chance of being
thrown out of the vehicle in a
crash is increased if the
doors are not locked. So, all
passengers should wear
safety belts properly and the
doors should be locked
whenever the vehicle is
driven.
.Young children who get into
unlocked vehicles may be
unable to get out. A child can
be overcome by extreme heat
and can suffer permanent
injuries or even death from
heat stroke. Always lock the
vehicle whenever leaving it. (Continued)

Traction Control System
(TCS)/StabiliTrak®Light
This light comes on briefly while
starting the vehicle.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the light comes on and stays on
while driving, there could be a
problem with the TCS/StabiliTrak
system and the vehicle might need
service. When this warning light is
on, the TCS/StabiliTrak system is off
and does not limit wheel spin.
The light flashes if the system is
active and is working to assist the
driver with directional control of the
vehicle in difficult driving conditions.
Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the vehicle is started.
If it does not, have the vehicle
serviced by your dealer. If the

If the light comes on and stays on
while driving, the vehicle may have
a problem with the cooling system.
Stop and turn off the vehicle to
avoid damage to the engine.
A warning chime sounds when this
light is on.
SeeEngine Overheating on
page 10-19 for more information.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the vehicle is
in ON/RUN. It provides information
about tire pressures and the TPMS.
When the Light is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A message in the Driver Information
Center (DIC) may also display. See
Tire Messages on page 5-49. Stop
as soon as possible, and inflate the
tires to the pressure value shown on
the Tire and Loading Information
label. SeeTires on page 10-40.

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10-12.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.

2. Replace the air cleaner cover bylowering it to meet the bottom of
the engine air cleaner/filter
assembly. Place the retaining
clips (1) on the engine air
cleaner/filter assembly and
secure. The rear tabs must be
secured into the lower portion of
the air cleaner.
3. Reconnect the air duct and tighten the air duct clamp (2).
4. Reconnect the electrical connector (3).
{Warning
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
{Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when you are driving.
Cooling System (Engine)
1. Engine Coolant Surge Tank
and Pressure Cap
2. Engine Cooling Fans (Out of View)
{Warning
The electric fans 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.
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.
The coolant level should be up to
the cold fill line. If it is not, there
might be a leak at the radiator
hoses, heater hoses, radiator, water
pump, or somewhere else in the
cooling system.

Vehicle Care 10-15
{Warning
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 vehicle if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans
should be running. If it is not, the
vehicle needs service. Turn off the
vehicle.
Cooling System (High
Voltage Battery)
During vehicle operation and also
during charging, the high voltage
battery cells in the vehicle are kept within a normal operating
temperature range. If the
temperature rises above this
temperature, the battery cooling
system turns on the air conditioning
compressor and cools the coolant
until the correct temperature is
reached. If the temperature falls
below this temperature, a high
voltage heater, located in the
battery, heats the coolant until the
correct temperature is reached.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled with
a 50/50 mixture of DEX-COOL
®
engine coolant and deionized water.
If using this mixture, nothing else
needs to be added.
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule on
page 11-2.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery coolant
reservoir is located in the engine
compartment. See
Engine
Compartment Overview on
page 10-8.
Check to see if coolant is visible in
the high voltage battery coolant
reservoir. If coolant is visible but the
