Section 2 Features and Controls
85

Trunk
{CAUTION:
It can be dangerous to drive with the
trunk lid open because carbon monoxide
(CO) gas can come into your vehicle. You
cannot see or smell CO. It can cause
unconsciousness and even death. If you
must drive with the trunk lid open or if
electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or
cooling system to its highest speed
and select the control setting that will
force outside air into your vehicle. See
Climate Control System.
If you have air outlets on or under
the instrument panel, open them
all the way.
SeeEngine Exhaust on page 122.
Opening the Trunk
To open the trunk from the outside, use the
Remote Keyless Entry (RKE) transmitter. See
Remote Keyless Entry (RKE) System Operation on
page 90for more information.
The ignition must be off, or the transaxle must be
in PARK (P) to open the trunk.
Remote Trunk Release
This feature is used to unlock the trunk from inside
the vehicle using the power door lock switch.
Press and hold the top
of the driver’s or front
passenger’s power door
lock switch to unlock
the trunk.
The vehicle must be in PARK (P) to unlock
the trunk.

Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
121

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:
Your 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 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.
122

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 122.
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 314.
{CAUTION:
It can be dangerous to get out of your
vehicle if the 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 you are on fairly level ground,
always set your parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 118.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 327.

Notice:If you keep driving your vehicle
with this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by
your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 341.This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.

You can run the engine to keep warm, but be
careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO
(carbon monoxide) gas to get inside. CO
could overcome you and kill you. You
cannot see it or smell it, so you might not
know it is in your vehicle. Clear away
snow from around the base of your
vehicle, especially any that is blocking
your exhaust pipe. And check around
again from time to time to be sure snow
does not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.
Run your engine only as long as you must. This
saves fuel. When you run the engine, make it go a
little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the
heat that you get and it keeps the battery charged.

Total Weight on Your Vehicle’s Tires
Be sure the vehicle’s tires are inated to the upper
limit for cold tires. These numbers can be found
on the Tire-Loading Information label. SeeLoading
Your Vehicle on page 319. Be sure not to go
over the GVW limit for the vehicle, or the GAWR,
including the weight of the trailer tongue. If a
weight distribution hitch is used, make sure not to
go over the rear axle limit before applying the
weight distribution spring bars.
Hitches
It is important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough
roads are a few reasons why the right hitch
is needed. Here are some rules to follow:
The rear bumper on the vehicle is not intended
for hitches. Do not attach rental hitches or
other bumper-type hitches to it. Use only
a frame-mounted hitch that does not attach to
the bumper.
If holes need to be made in the body of the
vehicle to install a trailer hitch, then be sure
to seal the holes later when the hitch is
removed. If the holes are not sealed, deadly
carbon monoxide (CO) from the exhaust
can get into the vehicle. SeeEngine Exhaust
on page 122. Dirt and water can, too.
Safety Chains
Chains should always be attached between the
vehicle and the trailer. Cross the safety chains
under the tongue of the trailer so that the tongue
will not drop to the road if it becomes separated
from the hitch. Instructions about safety chains
may be provided by the hitch manufacturer or by
the trailer manufacturer. Follow the manufacturer’s
recommendation for attaching safety chains
and do not attach them to the bumper. Always
leave just enough slack so the rig can be turned.
And, never allow safety chains to drag on the
ground.
