WHAT IS DRIVER ALERT
Driver alert alerts you if it determines that
you are becoming drowsy or if your driving

WHAT IS SPEED SIGN
RECOGNITION
Speed sign recognition detects speed limit
signs to inform you of the current speed
limit. Detected speed signs appear in the
information display.
HOW DOES SPEED SIGN
RECOGNITION WORK
Speed sign recognition uses a sensor
behind the interior mirror to detect speed
signs.
If your vehicle has speed sign recognition
with navigation, stored speed sign data
may influence the indicated speed limit
value.

LOAD CARRYING
PRECAUTIONS
Keep your loaded vehicle weight
within its design rating capability,
with or without a trailer. Properly
loading your vehicle provides
maximum return of vehicle design
performance. Before you load your
vehicle, become familiar with the
following terms for determining
your vehicle
’s weight rating, with
or without a trailer, from the
vehicle ’s Tire and Loading
Information label or Safety
Compliance Certification label. WARNING: Vehicles with
a higher center of gravity (utility
and four-wheel drive vehicles)
handle differently than vehicles
with a lower center of gravity
(passenger cars). Avoid sharp
turns, excessive speed and
abrupt steering in these vehicles.
Failure to drive cautiously
increases the risk of losing
control of your vehicle, vehicle
rollover, personal injury and
death. WARNING:
The
appropriate loading capacity of
your vehicle can be limited either
by volume capacity (how much
space is available) or by payload
capacity (how much weight the
vehicle should carry). Once you
have reached the maximum payload of your vehicle, do not
add more cargo, even if there is
space available. Overloading or
improperly loading your vehicle
can contribute to loss of vehicle
control and vehicle rollover.
WARNING:
Exceeding the
Safety Compliance Certification
label vehicle weight limits can
adversely affect the
performance and handling of
your vehicle, cause vehicle
damage and can result in the
loss of control of your vehicle,
serious personal injury or death. WARNING:
Do not use
replacement tires with lower
load carrying capacities than the
original tires because they may
lower your vehicle's GVWR and
GAWR limitations. Replacement
tires with a higher limit than the
original tires do not increase the
GVWR and GAWR limitations. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING: Exceeding any
vehicle weight rating can
adversely affect the
performance and handling of
your vehicle, cause vehicle
damage and can result in the
loss of control of your vehicle,
serious personal injury or death.
