If your brake pedal goes down farther man normal, your
rear drum brakes may need adjustment. Adjust them by
backing
up and firmly applying the brakes a few times.

Braking in Emergencies I
Use your anti-lock braking sysKem when you need to. .
With anti-lock, you can steer and brake at the same time.
In many emergencies, steering can help you .more. than
even the very best braking.

Power Steering
If you lose power steering a ssist becau Lse
the engine
stops or the system fails to function, you can steer but
it
will take much more effort.

Driving on Curves
It’s important to take- curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws of physics. when driviqg on curves. The

The tire has a puncture, cut, or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
.To find out what kind and size of tires you need; look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification
(TPC Spec)
-number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number.
That way,
your vehicle will continue
to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle.
If your tires have an all-season tread
design, the
TPC nu-mber will be followed. by a “MS”
(for mad and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure .they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
‘t
A CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different siz
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you
cows
have a crash. Be sure to use the same size and
type tires
on all four wheels.
It’s all right to drive with your compact spare (if
you have one). It

Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires
by
treadwear, traction and temperature performance. (This
applies only to vehicles sold
in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions
on a specified govement test course. For
