The CMBS does not activate if the
speed dif f erence between the two
vehicles is less than 10 mph (15
km/h). CMBS may also not
activate if you turn the steering
wheel to avoid the collision.
When the CMBS activates, the brake
lights also come on.
The collision mitigation brake
system (CMBS) can assist you when
there is a possibility of your vehicle
hitting the vehicle in f ront of you. It
is designed to reduce the speed of
your vehicle before an unavoidable
collision occurs and, if possible, to
alert you to a potential collision while
thereistimetopreventit.Hereisa
brief description of what the CMBS
can do:
When your speed is above 10 mph
(15 km/h), the CMBS radar
sensor in the f ront grille can sense
a vehicle ahead of you. When your
vehicle gets too close to the
vehicle ahead of you, the system
mayactivateawarningbeep,
causing automatic application of
the brakes, and causing the
e-pretensioners to tighten the
f ront seat belts (see page ). The CMBS consists of a radar
sensor in the f ront grille, a brake
actuator in the engine compartment,
an indicator on the instrument panel,
seat belt e-pretensioners on the f ront
seats,andanon/off switchonthe
dashboard.

Although your tire pressure is
monitored, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inf lation pressure as
specif ied on the vehicle placard and
intheowner’smanual(seepage).
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure. If you have a f lat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated f lat tire with the compact
sparetire(seepage ).
After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. Af ter several miles
(kilometers) driving, this indicator
begins to f lash, then stays on again.
You will also see a ‘‘CHECK TPMS
SYSTEM’’ message on the multi-
inf ormation display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
sparetirepressuretobesureitis
correct.
This indicator and the warning
message on the multi-inf ormation
display will go of f , af ter several miles
(kilometers) driving, when the spare
tire is replaced with the specifiedregular tire equipped with the tire
pressure monitor sensor.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

dealer as soon as possible.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
