3. Press the SET button and release it. The cruise
control light will come on in the instrument panel
cluster to show that the cruise control is on.
4. Take your foot off the accelerate pedal.
Resuming a Set Speed
Suppose the cruise control is set to a desired speed
and then the brakes are applied, or the clutch pedal
if you have a manual transmission. This shuts off
the cruise control. But it does not need to be reset.
Once the vehicle is going about 24 mph (39 km/h)
or more, briefly press the RESUME button.
The vehicle returns to the chosen speed and
stays there.
If the RESUME button is held longer, the vehicle keeps
going faster until the button is released or the brake
pedal is applied. Do not hold in the RESUME button,
unless you want the vehicle to go faster.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed.
•Use the accelerator pedal to get to a higher speed.
Press the SET button, then release the button and
the accelerator pedal. The vehicle will now
cruise at the higher speed.
•Press the RESUME button. Hold it there until the
desired speed is reached, and then release the
button. To increase the vehicle’s speed in very small
amounts, briefly press the RESUME button and
then release it. Each time this is done, the vehicle
goes about 1 mph (1.6 km/h) faster.
The accelerate feature only works after the cruise
control is turned on by pressing the SET button.
Reducing Speed While Using Cruise
Control
There are two ways to reduce the vehicle’s speed while
using cruise control:
•Press the SET button until the lower speed desired
is reached, then release it.
•To slow down in very small amounts, briefly press
the SET button. Each time this is done, the vehicle
goes about 1 mph (1.6 km/h) slower.

Passenger (P-Metric) Tire:A tire used on
passenger cars and some light duty trucks and
multipurpose vehicles.
Recommended Ination Pressure
:Vehicle
manufacturer’s recommended tire inflation
pressure as shown on the tire placard. See
Inflation - Tire Pressure on page 5-57and
Loading Your Vehicle on page 4-18.
Radial Ply Tire
:A pneumatic tire in which the
ply cords that extend to the beads are laid at
90 degrees to the centerline of the tread.
Rim
:A metal support for a tire and upon which
the tire beads are seated.
Sidewall
:The portion of a tire between the tread
and the bead.
Speed Rating
:An alphanumeric code assigned
to a tire indicating the maximum speed at which
a tire can operate.
Traction
:The friction between the tire and the
road surface. The amount of grip provided.
Tread
:The portion of a tire that comes into
contact with the road.Treadwear Indicators
:Narrow bands, sometimes
called wear bars, that show across the tread of a
tire when only 1/16 inch (1.6 mm) of tread remains.
SeeWhen It Is Time for New Tires on page 5-63.
UTQGS (Uniform Tire Quality Grading
Standards)
:A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings
are determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. SeeUniform
Tire Quality Grading on page 5-66.
Vehicle Capacity Weight
:The number of
designated seating positions multiplied by
150 lbs (68 kg) plus the rated cargo load.
SeeLoading Your Vehicle on page 4-18.
Vehicle Maximum Load on the Tire
:Load on
an individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.
Vehicle Placard
:A label permanently attached
to a vehicle showing the vehicle’s capacity
weight and the original equipment tire size and
recommended inflation pressure. See “Tire
and Loading Information Label” underLoading
Your Vehicle on page 4-18.

How to Check
Use a good quality pocket-type gage to check
tire pressure. You cannot tell if your tires are
properly inflated simply by looking at them.
Radial tires may look properly inflated even when
they are under-inflated. Check the tire’s inflation
pressure when the tires are cold. Cold means
your vehicle has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage firmly onto the valve to
get a pressure measurement. If the cold tire
inflation pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
inflation pressure is low, add air until you reach
the recommended amount.
If you overfill the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping
out dirt and moisture.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure readings
to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation
pressure label, you should determine the proper
tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling
and stopping ability.

When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
influence when you need new tires.
One way to tell when
it is time for new tires
is to check the treadwear
indicators, which will
appear when your
tires have only
1/16 inch (1.6 mm)
or less of tread remaining.You need new tires if any of the following statements
are true:•You can see the indicators at three or more places
around the tire.
•You can see cord or fabric showing through the
tire’s rubber.
•The tread or sidewall is cracked, cut, or snagged
deep enough to show cord or fabric.
•The tire has a bump, bulge, or split.
•The tire has a puncture, cut, or other damage that
cannot be repaired well because of the size or
location of the damage.
The rubber in tires degrades over time, even if they are
not being used. This is also true for the spare tire, if
your vehicle has one. Multiple conditions affect how fast
this aging takes place, including temperatures, loading
conditions, and inflation pressure maintenance. With
proper care and maintenance tires will typically wear out
before they degrade due to age. If you are unsure
about the need to replace your tires as they get older,
consult the tire manufacturer for more information.
