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.
SPEED SIGN RECOGNITION
PRECAUTIONS WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all limit
sensor performance. WARNING:
The system may not
operate properly if the sensor is blocked.
Keep the windshield free from obstruction.
Note: Do not carry out windshield repairs in
the immediate area surrounding the sensor.
Note: If your vehicle has a suspension kit
not approved by us, the system may not
correctly function. Note:
The system may not detect all speed
signs and may incorrectly read signs.
Note: Always fit our original parts when
replacing headlamp bulbs. Other bulbs may
reduce system performance.
SPEED SIGN RECOGNITION
LIMITATIONS
Speed sign recognition may not operate
correctly due to:
• Outdated map data.
• Incorrect recognition of speed limits by
the sensor of signs on parallel roads or
exit ramps.
• Missed recognition of faded, dirty, or
distorted signs.

•
Use a spray with a 40° wide spray angle
pattern.
• Keep the nozzle at a 12 in (305 mm)
distance and 90° angle to your vehicle's
surface.
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than 179°F (82°C).
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
CLEANING CAMERA LENSES AND
SENSORS
We recommend that you only use lukewarm
or cold water and a soft cloth to clean the
camera lens and sensors.
Note: Do not pressure wash camera lens
and sensors. CLEANING THE UNDERBODY
Flush the complete underside of your vehicle
frequently. Keep body and door drain holes
free from packed dirt.
Rear suspension components may require
regular cleaning with a power washer or a
thorough rinse with a strong stream of water
if the vehicle is operated in dusty or muddy
environments. Rear leaf springs or other
suspension components may emit squeaking
or popping noises while operating the
vehicle if particles, such as dirt, rocks, or
other debris, are present in the components.
CLEANING THE INTERIOR
CLEANING THE INSTRUMENT PANEL
WARNING:
Do not use chemical
solvents or strong detergents when
cleaning the steering wheel or instrument
panel to avoid contamination of the airbag
system. We recommend that you only clean the
instrument panel and cluster lens with a
damp soft cloth. Dry the area with a clean,
soft cloth.
For additional information and assistance,
we recommend that you contact an
authorized dealer.
Note:
Avoid cleaners or polishes that
increase the gloss of the upper portion of
the instrument panel. The dull finish in this
area helps protect you from undesirable
windshield reflection.
CLEANING PLASTIC
We recommend that you only use a mild
soap and water solution on a soft cloth. Dry
the area with a clean, soft cloth.
CLEANING DISPLAYS AND SCREENS
We recommend that you only use a
microfiber cloth in a circular motion to clean
off the fingerprint or dust.

USING SNOW CHAINS
WARNING: Do not exceed 30 mph
(50 km/h). Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not use snow chains
on snow-free roads. WARNING:
Only fit snow chains to
specified tires. WARNING:
If your vehicle is fitted
with wheel trims, remove them before
fitting snow chains. WARNING:
If you choose to install
snow tires on your vehicle, they must be
the same size, construction, and load range
as the original tires listed on the tire
placard, and they must be installed on all
four wheels. Mixing tires of different size
or construction on your vehicle can
adversely affect your vehicle's handling
and braking, and may lead to loss of
vehicle control. WARNING:
Wheels and tires must
be the same size, load index and speed
rating as those originally fitted on the
vehicle. Use of any other tire or wheel can
affect the safety and performance of your
vehicle. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure. Follow
the recommended tire inflation pressures found on the Safety Compliance
Certification label, or the Tire Label on the
B-Pillar or the edge of the driver door.
Failure to follow this instruction could result
in loss of vehicle control, vehicle rollover,
or personal injury or death.
Only use snow chains on rear wheels. Install
snow chains in pairs. Do not use
self-tensioning snow chains.
Only use snow chains on the following
specified tire sizes. Only install chains that
are 15mm or less (SAE Class S chains).
• 265/70R17
• 275/65R18
We recommend you use steel wheels of the
same size and specification if snow chains
are required because chains may chip
aluminum wheels.
Follow these guidelines when using snow
tires and traction devices:
