Loss of Control
Let us review what driving experts say about what
happens when the three control systems (brakes,
steering and acceleration) do not have enough friction
where the tires meet the road to do what the driver
has asked.
In any emergency, do not give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not “overdriving”
those conditions. But skids are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
are not rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.Remember: Any traction control system helps avoid only
the acceleration skid. If your TCS system is off, then
an acceleration skid is also best handled by easing your
foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety,
you will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration or braking
(including engine braking by shifting to a lower gear).
Any sudden changes could cause the tires to slide. You
may not realize the surface is slippery until your vehicle is
skidding. Learn to recognize warning clues — such as
enough water, ice or packed snow on the road to make
a “mirrored surface” — and slow down when you have
any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.
4-14

Your anti-lock brakes improve your vehicle’s stability
when you make a hard stop on a slippery road.
Even though you have the anti-lock braking system,
you will want to begin stopping sooner than you would
on dry pavement. SeeBraking on page 4-6.
•Allow greater following distance on any slippery road.
•Watch for slippery spots. The road might be fine
until you hit a spot that is covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the sun can not reach: around
clumps of trees, behind buildings or under bridges.
Sometimes the surface of a curve or an overpass
may remain icy when the surrounding roads are
clear. If you see a patch of ice ahead of you, brake
before you are on it. Try not to brake while you are
actually on the ice, and avoid sudden steering
maneuvers.
If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with your
vehicle unless you know for sure that you are near help
and you can hike through the snow. Here are some things
to do to summon help and keep yourself and your
passengers safe:
•Turn on your hazard flashers.
•Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
4-26

•Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats — anything you can wrap around yourself or
tuck under your clothing to keep warm.
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 can not 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. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on with
your headlamps. Let the heater run for a while.

Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to find. Never use leaded gasoline or any other fuel
not recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel would not
be covered by your warranty.
To check the fuel availability, ask an auto club, or contact
a major oil company that does business in the country
where you will be driving.
Filling Your Tank
{CAUTION:
Fuel vapor burns violently and a fuel re can
cause bad injuries. To help avoid injuries to you
and others, read and follow all the instructions
on the pump island. Turn off your engine when
you are refueling. Do not smoke if you are near
fuel or refueling your vehicle. Keep sparks,
ames and smoking materials away from fuel.
CAUTION: (Continued)
CAUTION: (Continued)
Do not leave the fuel pump unattended when
refueling your vehicle — this is against the law
in some places. Keep children away from the
fuel pump; never let children pump fuel.
To open the fuel filler door,
pull up on the fuel filler
door release lever located
on the floor to the left
of the driver’s seat.
The fuel cap is located behind a hinged door on the
passenger’s side of your vehicle. To remove the
fuel cap, turn it slowly to the left (counterclockwise).
5-7

When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. The diagnostic system can
determine if the fuel cap has been left off or improperly
installed. This would allow fuel to evaporate into the
atmosphere. SeeMalfunction Indicator Lamp on
page 3-39.
{CAUTION:
If a re starts while you are refueling, do not
remove the nozzle. Shut off the ow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not t properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp on
page 3-39.

If the oil pressure light

cluster, it means you
need to check your engine
oil level right away.
For more information, seeOil Pressure Light on
page 3-42.
You should check your engine oil level regularly; this is
an added reminder.

1. Park the vehicle on a level surface.
You can remove the coolant surge tank pressure
cap when the cooling system, including the coolant
surge tank pressure cap and upper radiator
hose, is no longer hot. Turn the pressure cap slowly
counterclockwise (left) about two or two and
one-half turns. If you hear a hiss, wait for that to
stop. This will allow any pressure still left to be
vented out the discharge hose.
2. Then keep turning the
pressure cap slowly,
and remove it.
3. Fill the coolant surge tank with the proper mixture
to the MAX (A) mark on the coolant surge tank.
Wait about five minutes, then check to see if
the level is below the MAX (A) mark. If the level is
below the MAX (A) mark, add additional coolant
to bring the level up to the MAX (A) mark. Repeat
this procedure until the level remains constant
at the MAX (A) mark for at least five minutes.
