SAFETY 207
Supplemental Seat-Mounted Side Air Bags (SABs) are
located in the outboard side of the front seats. The SABs are
marked with “SRS AIRBAG” or “AIRBAG” on a label or on
the seat trim on the outboard side of the seats.Supplemental Seat-Mounted Side Air Bag Label
The SABs (if equipped with SABs) may help to reduce the
risk of occupant injury during certain side impacts, in addi -
tion to the injury reduction potential provided by the seat
belts and body structure.
When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB deploys
through the seat seam into the space between the occupant and the door. The SAB moves at a very high speed and with
such a high force that it could injure occupants if they are not
seated properly, or if items are positioned in the area where
the SAB inflates. Children are at an even greater risk of injury
from a deploying air bag.
Supplemental Side Air Bag Inflatable Curtains (SABICs)
— If Equipped
Your vehicle may be equipped with Supplemental Side Air
Bag Inflatable Curtains (SABICs). If your vehicle is equipped
with Supplemental Side Air Bag Inflatable Curtains
(SABICs), please refer to the information below.
Supplemental Side Air Bag Inflatable Curtains (SABICs) are
located above the side windows. The trim covering the
SABICs is labeled “SRS AIRBAG” or “AIRBAG.”
WARNING!
Do not use accessory seat covers or place objects between
you and the Side Air Bags; the performance could be
adversely affected and/or objects could be pushed into
you, causing serious injury.

292 STARTING AND OPERATING
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the SET (-)
button and release. The instrument cluster display will show
the set speed.
If the system is set when the vehicle speed is below 20 mph
(32 km/h), the set speed shall be defaulted to 20 mph
(32 km/h). If the system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be the current
speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary vehicle in front of
your vehicle in close proximity.
Remove your foot from the accelerator pedal, after the ACC
has been set. If you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
• The message “ACC DRIVER OVERRIDE” will display in the instrument cluster display.
• The system will not be controlling the distance between your vehicle and the vehicle ahead. The vehicle speed will
only be determined by the position of the accelerator
pedal.
To Cancel
The following conditions cancel the system:
• The brake pedal is applied.
• The CANC (cancel) button is pushed.
• An Anti-Lock Brake System (ABS) event occurs.
• The gear selector is removed from the DRIVE position.
• The Electronic Stability Control/Traction Control System(ESC/TCS) activates.
• The vehicle parking brake is applied.
• Driver seatbelt is unbuckled at low speeds.
• Driver door is opened at low speeds.
• A Trailer Sway Control (TSC) event occurs.
• The driver switches ESC to full-off mode.
• The braking temperature exceeds normal range (over -
heated).

Power Distribution Center
The Power Distribution Center is located in the engine
compartment near the battery. This center contains cartridge
fuses, micro fuses, relays, and circuit breakers. A description
of each fuse and component may be stamped on the inside
cover, otherwise the cavity number of each fuse is stamped
on the inside cover that corresponds to the following chart.Power Distribution Center Location

3. There are travel stops on both sides of the glove compart-
ment. Push inward on right side of the glove compart -
ment travel stop to disengage the stop. Then pull the right
of the glove compartment outward (away from the hinge)
to disengaging the right side of the compartment from the
hinge. Continue by removing the left side from the hinge
by slightly lowering the compartment while pulling
outward until it is completely disengaged from the hinge.

6. Install the cabin air filter with the arrow on the filter pointing toward the floor. When installing the filter
cover, press on each end until you hear an audible click.
7. Reinstall the glove compartment on the hinges.

CAUTION!
The cabin air filter is identified with an arrow to indicate
airflow direction through the filter. Failure to properly
install the filter will result in the need to replace it more
often. 7

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service or immediately if
the brake system warning lamp indicates system failure.
If necessary, add fluid to bring level within the designated
marks on the side of the reservoir of the brake master
cylinder. Be sure to clean the top of the master cylinder area
before removing cap.With disc brakes the fluid level can be expected to fall as the
brake linings wear. However, an unexpected drop in fluid
level may be caused by a leak and a system check should be
conducted.
Refer to “Fluids And Lubricants” in “Technical Specifica
-
tions” for further information.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. Driving with your foot resting or riding on
the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.
WARNING!
• Use only manufacturer's recommended brake fluid. Refer to “Fluids And Lubricants” in “Technical Speci -
fications” for further information. Using the wrong
type of brake fluid can severely damage your brake
system and/or impair its performance. The proper type
of brake fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
• To avoid contamination from foreign matter or mois -
ture, use only new brake fluid or fluid that has been in
a tightly closed container. Keep the master cylinder
reservoir cap secured at all times. Brake fluid in a open
container absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil unexpect -
edly during hard or prolonged braking, resulting in
sudden brake failure. This could result in a collision.

NOTE:
• P (Passenger) — Metric tire sizing is based on U.S. designstandards. P-Metric tires have the letter “P” molded into
the sidewall preceding the size designation. Example:
P215/65R15 95H.
• European — Metric tire sizing is based on European design standards. Tires designed to this standard have the
tire size molded into the sidewall beginning with the
section width. The letter "P" is absent from this tire size
designation. Example: 215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S. design standards. The size designation for LT-Metric tires
is the same as for P-Metric tires except for the letters “LT”
that are molded into the sidewall preceding the size desig -
nation. Example: LT235/85R16.
• Temporary spare tires are designed for temporary emer -
gency use only. Temporary high pressure compact spare
tires have the letter “T” or “S” molded into the sidewall
preceding the size designation. Example: T145/80D18
103M.
• High flotation tire sizing is based on U.S. design standards and it begins with the tire diameter molded into the side -
wall. Example: 31x10.5 R15 LT.

H = Speed Symbol
• A symbol indicating the range of speeds at which a tire can carry a load corresponding to its load index under certain oper -
ating conditions
• The maximum speed corresponding to the speed symbol should only be achieved under specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and posted speed limits)
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:
• XL = Extra load (or reinforced) tire, or
• LL = Light load tire or
• C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load – Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure – Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire EXAMPLE:
