Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the
gas carbon monoxide (CO), which you
cannot see or smell. It can cause
unconsciousness and death.
You might have exhaust coming in if:
The exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a
collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when
driving over high points on the road
or over road debris.
Repairs were not done correctly.
Your vehicle or the exhaust system
has been modied improperly.
If you ever suspect exhaust is coming
into your vehicle:
Drive it only with all the windows
down to blow out any CO; and
Have your vehicle xed immediately.
139

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 139.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is
at the highest setting. One place this
can happen is a garage. Exhaust — with
CO — can come in easily. NEVER park
in a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 286.
{CAUTION:
It can be dangerous to get out of your
vehicle if the automatic transmission shift
lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the
engine is running unless you have to.
If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle
will not move, even when it is on fairly
level ground, always set the parking brake
and move the automatic transmission
shift lever to PARK (P), or the manual
transmission shift lever to NEUTRAL.

Dome Lamp Override
E(Dome Override):Press this button, located
below the exterior lamp control, to turn the
dome lamp off even when a door is opened.
SeeExterior Lamps on page 170for more
information on location.
To return the lamp to automatic operation,
press the button again.
Exit Lighting
With exit lighting, the interior lamps will come
on when you remove the key from the ignition.
The lamps will not come on if the dome override
button is pressed in.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not
be spinning fast enough at idle to produce all the
power that is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged
into accessory power outlets.Battery Run-Down Protection
This feature shuts off the dome lamp if it is left
on for more than 20 minutes when the ignition
is in LOCK. This will help prevent your battery
from running down.

Recirculation is only available in the bi-level and
vent modes. It should only be used while in bi-level
and vent modes. Recirculation is not available,
and the light will not come on or ash while in heat,
oor, oor/defog, or defrost modes.
#(Air Conditioning):Press this button to turn
the air conditioning system on or off. An indicator
light on the button will come on to let you know
the air conditioning is activated. When the system
is on, this setting cools and dehumidies the
air entering your vehicle.
The air conditioning will not function if the fan is
turned off.
You may notice a slight change in engine
performance when the air conditioning compressor
shuts off and turns on again. This is normal.
The system is designed to make adjustments to
help with fuel economy while still maintaining
the selected temperature.The air conditioning system removes moisture
from the air, so you may sometimes notice a
small amount of water dripping underneath
your vehicle while idling or after turning off the
engine. This is normal.Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool
window glass. This can be minimized if the
climate control system is used properly. There
are two modes to clear fog or frost from your
windshield and side windows. Use the defog
mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly. For best results, clear all snow and
ice from the windshield before defrosting.

Warning Lights, Gages,
and Indicators
This part describes the warning lights and
gages on your vehicle. The pictures help to
locate them.
Warning lights and gages can signal that
something is wrong before it becomes serious
enough to cause an expensive repair or
replacement. Paying attention to the warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As the details show on the next few pages,
some warning lights come on briey when you
start the engine just to let you know they are
working. If you are familiar with this section, you
should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together
to let you know when there is a problem with
your vehicle.
When one of the warning lights comes on and
stays on as you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
So please get to know your vehicle’s warning
lights and gages. They can be a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information
Center (DIC) on page 198for more information.

Speedometer and Odometer
Your speedometer lets you see your speed in
both miles per hour (mph) and kilometers
per hour (km/h).
Your odometer shows how far your vehicle
has been driven, in either miles (used in the
United States) or kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running. Simply press the trip information
stem. See “Odometer” underDIC Controls
and Displays on page 198for more information.
You may wonder what happens if your vehicle
needs a new odometer installed. If the new one
can be set to the mileage total of the old odometer,
then it must be. But if it cannot, then it is set at
zero, and a label must be put on the driver’s door
to show the old mileage reading when the new
odometer was installed.
Trip Odometer
Your vehicle has a trip odometer that can tell
you how far your vehicle has been driven since
you last set the trip odometer to zero.
See “Trip Odometer” underDIC Controls and
Displays on page 198for more information.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty.
Do not operate the engine with the tachometer
in the shaded warning area.

When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. SeeParking Brake on page 133for more
information. The light will stay on if your parking
brake does not release fully. If it stays on after your
parking brake is fully released, it means you have a
brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is harder to push, or the pedal may go closer
to the oor. It may take longer to stop. If the light
is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 299.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the Anti-Lock Brake
System (ABS), this light
will come on briey when
you start your engine
to show it is working.
Then it will turn off.
This is normal.
If the light stays on, or comes on when you are
driving, your vehicle needs service. If the regular
brake system warning light is not on, you still
have brakes, but you do not have anti-lock brakes.
If the regular brake system warning light is also
on, you do not have anti-lock brakes and there is
a problem with your regular brakes. SeeBrake
System Warning Light on page 189.
The ABS warning light should come on briey
when you turn the ignition key to ON. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
