Your Anti-Lock Brake System (ABS) improves your
vehicle's stability when you make a hard stop on
a slippery road. Even though you have ABS, you will
want to begin stopping sooner than you would on
dry pavement. See
Anti-Lock Brake System (ABS)
on page 4-7.
·Allow greater following distance on any slippery road.
·Watch for slippery spots. The road might be ®ne 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 cannot reach, such as
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 ¯ashers.
·Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
·Put on extra clothing or wrap a blanket around you.
If you do not have blankets or extra clothing, make
body insulators from newspapers, burlap bags,
rags, ¯oor mats Ð anything you can wrap around
yourself or tuck under your clothing to keep warm.

If Your Vehicle is Stuck in Sand,
Mud, Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as rocking
can help you get out when you are stuck, but you
must use caution.
{CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transmission or other parts of the
vehicle can overheat. That could cause an
engine compartment ®re or other damage.
When you are stuck, spin the wheels as little as
possible. Do not spin the wheels above 35 mph
(55 km/h) as shown on the speedometer.
Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transmission
back and forth, you can destroy your transmission.
For more information about using tire chains on your
vehicle, see
Tire Chains on page 5-67.
Rocking Your Vehicle to Get It Out
First, turn your steering wheel left and right. That
will clear the area around your front wheels. If your
vehicle has traction control, you should turn the system
off. See
Traction Control System (TCS) on page 4-9.
Then shift back and forth between REVERSE (R) and a
forward gear, spinning the wheels as little as possible.
For a manual transmission, shift slowly between
either FIRST (1) or SECOND (2) and REVERSE (R),
allowing the wheels to stop before shifting into
gear. Release the accelerator pedal while you shift, and
press lightly on the accelerator pedal when the
transmission is in gear. By slowly spinning your wheels
in the forward and reverse directions, you will cause
a rocking motion that may free your vehicle. If that does
not get you out after a few tries, you may need to be
towed out. If you do need to be towed out, see
Towing
Your Vehicle on page 4-34.

Engine Oil
If the Service Engine Oil message appears on the trip
computer display, it means you need to check your
engine oil level right away. For more information, see
Trip Computer on page 3-33. You should check
your engine oil level regularly; this is an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

Power Steering Fluid
The power steering ¯uid reservoir is located toward the
front of the engine compartment on the driver's side
of the vehicle. See
Engine Compartment Overview on
page 5-12for reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering ¯uid
unless you suspect there is a leak in the system or
you hear an unusual noise. A ¯uid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
The ¯uid level should be checked after the vehicle has
been driven for at least 20 minutes, so that the ¯uid
is warm. A cold level check can be done after the engine
has been off for at least ®ve hours. However, the hot
level check is recommended.
The ¯uid level can be viewed through the reservoir. The
level markings are next to the ¯uid window. When the
¯uid is cold, the level should be between the COLD MIN
(Minimum) and MAX (Maximum) marks. When the
vehicle has been driven for at least 20 minutes and the
¯uid is hot, the level should be between the HOT
MIN and MAX marks.
If ¯uid must be added, turn the cap counterclockwise to
the stop; then the cap can be lifted off. Do not over®ll
the reservoir and remember to replace the cap
tightly when you are ®nished and clean up any
spilled ¯uid.
If you often need to add ¯uid, you should see
your dealer.
What to Use
To determine what kind of ¯uid to use, seeRecommended Fluids and Lubricants on page 6-12.
Always use the proper ¯uid. Failure to use the proper
¯uid can cause leaks and damage hoses and seals.

Tire Size
The following illustration shows an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as the
®rst character in the tire size means a passenger
vehicle tire engineered to standards set by the U.S. Tire
and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example, if
the tire size aspect ratio is 60, as shown in item C of the
illustration, it would mean that the tire's sidewall is
60 percent as high as it is wide.
(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The
letter R means radial ply construction; the letter D means
diagonal or bias ply construction; and the letter B means
belted-bias ply construction.(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters represent
the load range and speed rating of the tire. The load
index represents the load carry capacity a tire is certi®ed
to carry. The load index can range from 1 to 279. The
speed rating is the maximum speed a tire is certi®ed
to carry a load. Speed ratings range from A to Z.
Tire Terminology and De®nitions
Air Pressure:The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure
is expressed in pounds per square inch (psi) or
kilopascal (kPa).
Accessory Weight:This means the combined weight
of optional accessories. Some examples of optional
accessories are, automatic transmission, power steering,
power brakes, power windows, power seats, and air
conditioning.
Aspect Ratio:The relationship of a tire's height to its
width.
Belt:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be made
from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrapped by
steel cords that hold the tire onto the rim.

If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your vehicle's tires properly.
If air goes out of a tire, it is much more likely to leak out
slowly. But if you should ever have a blowout, here
are a few tips about what to expect and what to do:
If a front tire fails, the ¯at tire will create a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel ®rmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you would
use in a skid. In any rear blowout remove your foot from
the accelerator pedal. Get the vehicle under control
by steering the way you want the vehicle to go. It may
be very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a ¯at tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a ¯at tire.
If a tire goes ¯at, the next part shows how to use the
jacking equipment to change a ¯at tire safely.
