Your vehicle will stay in the storage mode until the
ignition key is turned out of LOCK. The system will
ªwake
-upº when the door key is inserted into the door,
however, your vehicle will remain in the storage mode.
The ignition must be out of LOCK before the battery
guard is disabled.
Comfort Controls and Radio System Personalization
These features allow both drivers to personalize their
own climate control settings as well as their radio
settings. For more information, see ªClimate Control
Personalizationº and ªRadio Personalizationº in
the Index.
Continuous Variable Road Sensing
Suspension (CVRSS) (ETC Only)
The CVRSS automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through a
computer used to control and monitor the suspension
system. The controller receives input from various
sensors to determine the proper system response. If the
controller detects a problem within the system, the
Driver Information Center (DIC) will display a
SERVICE RIDE CONTROL message. If this message
appears, have your vehicle serviced at your dealership.
Oil Life Indicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and your
driving patterns. To see the display, press the SKIP
INFO button several times until XX OIL LIFE LEFT
appears. If you see 99% OIL LIFE LEFT, 99 percent of
your current oil life remains.

The Driver Information Center (DIC) may display a
CHANGE ENGINE OIL message. Always keep a
written record of the mileage and date when you
changed your oil. For more information, see the
Maintenance Schedule booklet. If you see CHANGE
ENGINE OIL, it means that you have no oil life left and
you should change your engine oil right away.
The system should indicate changing the oil between
3,000 miles (5 000 km) and 7,500 miles (12 500 km).
It may indicate changing the oil before 3,000 miles
(5 000 km) depending on your driving habits. If the
vehicle has been driven 7,500 miles (12 500 km), it willindicate to change the oil. If you drive in a dusty area,
you should change your oil every 3,000 miles
(5 000 km) or three months (whichever comes first)
unless the display indicates changing it sooner. See
ªEngine Oil, When to Changeº in the Index. The
system doesn't check how much oil you have, so you'll
still have to check for that. To see how, see ªEngine Oilº
in the Index.
When the oil is changed, you'll need to reset the system.
See ªOil Life Indicator, How to Resetº in the Index.

Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble
-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?
Highway Hypnosis
Is there actually such a condition as ªhighway hypnosisº?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the wind
against the vehicle that can make you sleepy. Don't let it
happen to you! If it does, your vehicle can leave the
road in less than a second, and you could crash and
be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:

Make sure your vehicle is well ventilated, with a
comfortably cool interior.

Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.

If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.

4-37 When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

Start your engine;

Shift into a gear; and

Be sure the parking brake has released.
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 booklet
for more on this. Things that are especially important in
trailer operation are automatic transaxle fluid (don't
overfill), engine oil, drive belt, cooling system and brake
system. If you're trailering, it's a good idea to review
this information 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 ªEngine Overheatingº
in the Index.

Engine Overheating
You will find an ENGINE COOLANT HOT, IDLE
ENGINE message or an ENGINE OVERHEATED,
STOP ENGINE message on the Driver Information
Center (DIC). You will also hear a chime. There is also
an engine temperature warning light and/or gage on the
instrument panel. See ªEngine Coolant Temperature
Warning Lightº or ªEngine Coolant Temperature Gageº
in the Index.
Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED, STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups of 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 ªEngine Oilº
in the Index.

Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
A. Coolant Surge Tank with Pressure Cap
B. Electric Engine Fans
CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don't do anything else until it cools down.

yellowblue
5-16
CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like 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 wouldn't
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a 50/50 mixture of clean, drinkable water
and DEX
-COOL
coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So use the recommended coolant.
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. Don't spill coolant on a hot engine.
