Safety system of your vehicle
Front air bags are not designed to
inflate in rear collisions, because
occupants are moved backward by
the force of the impact. In this case,
inflated air bags would not provide
any additional benefit.
Front air bags may not inflate in side
impact collisions, because occu-
pants move in the direction of the
collision, and thus in side impacts,
front air bag deployment would not
provide additional occupant protec-
tion.
However, side and curtain air bags
may inflate depending on the intensi-
ty, vehicle speed and angles of
impact. In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.
Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to "ride" under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
"underride" collisions.

Driving your vehicle
Changing lanes
When a vehicle changes lanes in
front of you, the AEB system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the AEB sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance. Detecting the vehicle in front of you
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The AEB system may not be able to
detect the cargo extending from the
vehicle.
In these instances, you must main-
tain a safe braking distance from the
rearmost object, and if necessary,
depress the brake pedal to reduce
your driving speed in order to main-
tain distance.

Detecting pedestrians
The sensor may be limited when:
The pedestrian is not fully detectedby the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
The outside lighting is too bright (e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night)
It is difficult to detect and distin- guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd
Information
In some instances, the AEB system
may be cancelled when subjected to
electromagnetic interference.
Information
This device complies with Part 15 of
the FCC rules.
Operation is subject to the following
two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any inter- ference received, including interfer-
ence that may cause undesired
operation.

Do not use the AutomaticEmergency Braking system
when towing a vehicle.
Application of the AEB sys-
tem while towing may
adversely affect the safety of
your vehicle or the towing
vehicle
Use extreme caution when the vehicle in front of you has
cargo that extends rearward
from the cab, or when the
vehicle in front of you has
higher ground clearance.
(Continued)
(Continued)
The AEB system is designedto detect and monitor the
vehicle ahead or detect a
pedestrian in the roadway
through radar signals and
camera recognition. It is not
designed to detect bicycles,
motorcycles, or smaller
wheeled objects such as lug-
gage bags, shopping carts, or
strollers.
Never try to test the operation of the AEB system. Doing so
may cause severe injury or
death.

When driving with the compact spare
tire mounted to your vehicle:
Check the tire pressure afterinstalling the compact spare tire.
The compact spare tire should be
inflated to 60 psi (420 kPa).
Do not take this vehicle through an automatic car wash while the com-
pact spare tire is installed.
Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
The compact spare tire’s tread life is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
Do not use more than one compact spare tire at a time.Information
When the original tire and wheel are
repaired and reinstalled on the vehi-
cle, the lug nut torque must be set cor-
rectly. The correct lug nut tightening
torque is 79~94 lbf·ft (11~13 kgf·m).
To prevent damaging the compact
spare tire and your vehicle:
Drive slowly enough for the roadconditions to avoid all hazards,
such as a potholes or debris.
Avoid driving over obstacles. The compact spare tire diameter
is smaller than the diameter of a
conventional tire and reduces
the ground clearance approxi-
mately 1 inch (25 mm).
Do not use tire chains on the compact spare tire. Because of
the smaller size, a tire chain will
not fit properly.
Do not use the compact spare tire on any other wheels, nor
should standard tires, snow
tires, wheel covers or trim rings
be used with the compact spare
wheel.

Maintenance
Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
Wheel Replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Information
A wheel in the different size may
adversely affect the wheel bearing,
braking, stopping, handling, ground
clearance, body-to-tire clearance,
snow-chain clearance, speedometer,
odometer, headlamp angle and
bumper height.
i
The original tire should be
repaired or replaced as soon as
possible to avoid failure of the
spare and loss of vehicle con-
trol resulting in an accident. The
compact spare tire is for emer-
gency use only. Do not operate
your vehicle over 50 mph (80
km/h) when using the compact
spare tire.
