Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it
can make
it impossible
to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it.
With the ignition off and the driver’s door open, you’ll
hear a chime reminding you to remove your key from
the ignition and take
it with you. Always do this. Your
steering wheel will be locked, and
so will your ignition
and transaxle. And remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out
of sight.
Put them in a storage area, or take them with you.

Use this position for slightly larger loads.
When installing the net in either position, be sure the
“up label”
(A) is pointing up.
Ashtrays and Cigarette Lighter
Push and release the cover to reveal the front ashtray,
lighter and accessory power outlet.
NOTICE:
Don’t put papers and other things that burn
into your ashtrays.
If you do, cigarettes or
other smoking materials could set them on fire,
causing damage.
To open either rear ashtray, you may press and release
the cover or pull up the cover lid.
To clean an ashtray, make sure the cover is open fully,
then lift out the ashtray by pulling on the snuffer.
To use a lighter, just push it in all the way and let go.
When it’s ready, it will pop back by itself.
NOTICE:
Don’t hold a cigarette lighter in with your hand
while it is heating.
If you do, it won’t be able to
back away from the heating element when it’s
ready. That can make it overheat, damaging the
lighter and the heating element.

Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the gage pointer moves into the red warning zone,
your engine is hot.
To prevent engine overheating, the
air conditioning compressor will turn
off automatically,
a fast-pulsed chime will sound, and the message
ENGINE
HOT ... A/C OW will appear in the information
center.
As the engine cools down, the air conditioning
compressor will automatically turn back on. If
the coolant temperature is over
261 OF (127 “C),
the message HOT. ..STOP ENGINE will appear. 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.
The section “Problems on the Road,”
in this manual
explains what to
do. See “Engine Overheating” in
the Index.
If your coolant level
is low, the message LOW ENGINE
COOLANT will appear on the Driver Information
Center. Check your coolant level
as soon as possible.
See “Engine Coolant” in the Index.

Heating
In cold weather, if the automatic mode is selected
(AUTO-PUSH knob indicator light is on), the system
will automatically direct the airflow out of the lower
floor outlets and the temperature door will be positioned
at the full hot position. You can choose the extreme
comfort setting of
90°F (32°C) but the system will not
warm
up any faster by selecting the extreme
comfort setting.
In cold weather, the system will delay turning on the fan
to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature
of the engine coolant increases. Rotating the
AUTO FAN
knob will override this delay by turning off
the automatic fan control mode and changing the
fan speed.
Ventilation System
Your vehicle’s flow-through ventilation system always
allows outside air
to flow through your vehicle when it
is moving, even when the system is off.
The direction of the air can be controlled by adjusting or
closing the outlets
in the instrument panel. Rotate the
control between the front outlets upward to open the
outlets and downward to close the outlets. Adjust the
direction of airflow
from side to side with the controls in
each outlet.

NOTICE:
Steering Wheel Controls for Climate Control
Don’t use a razor blade or something else sharp
on the inside
of the rear window. If you do, you
could cut or damage the warming grid, and the repairs wouldn’t be covered by your warranty.
Passenger Temperature Control
With this feature, the right
front seat passenger can
control the comfort setting
for their own zone. To use
this feature, adjust the
control on the passenger’s
side armrest to the desired
comfort level.
The passenger’s temperature control on the passenger’s
armrest will illuminate only
if the headlamps or parking
lamps are on.
~ Some heating and cooling
controls can be adjusted
at the steering wheel.
Other touch controls
also operate some audio
controls. See “Audio
Steering Wheel Controls”
later in
this section.

your current comfort setting in the digital display. Press
the upper part of the
TEMP button again to provide a
warmer comfort setting or press the lower part
of the
TEMP button again to provide a cooler comfort setting.

But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking

5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer,
See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each
of these is covered in this manual, and the Index
will help
you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Engine Overheating
Attach a separate safety
chain around the outboard
end of each lower
control
arm.
You will find a coolant temperature gage on your
vehicle’s instrument panel. Your driver information
center will also display messages about engine
overheating. See “Coolant Temperature Gage”
in the Index.
Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
message HOT
STOP ENGINE is displayed, an overheat
protection mode which alternates firing groups of four
cylinders helps prevent engine damage. In this mode,
you will notice a loss in power and engine performance.
This operating mode allows your vehicle to be driven to
a safe place in an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause
of coolant loss, change the oil and reset
the oil life indicator. See “Engine Oil, When to
Change” in the Index.

Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine 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 it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center.
If it is, you may have a leak in the
radiator hoses, heater hoses, radiator, water
pump or
somewhere else in the cooling system,
NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine on, check to
see
if the electric engine cooling fans are running. If the
engine
is overheating, both fans should be running. If
they aren’t, your vehicle needs service.
