Tire Pressure Monitoring System (TPMS)
Instead of directly measuring the pressure in each tire, the TPMS on this vehicle
monitors and compares the rolling radius and rotational characteristics of each
wheel and tire while you are driving to determine if one or more tires are
significantly under-inflated. This will cause the low tire pressure/TPMS
indicator to come on and a message to appear
on the driver information interface.1 Tire Pressure Monitoring System (TPMS)
The system does not monitor the tires when driving
at low speed.
Conditions such as low ambient temperature and
altitude change directly a ffect tire pressure and can
trigger the low tire pressure/TPMS indicator to come on.
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS may not function pr operly if tire type and
size are mixed. Make sure to use the same size and
type of tire. 2 Checking and Maintaining Tires P. 646
The low tire pressure/TPMS indicator may come on
with a delay or may not come on at all when:
•You rapidly accelerate, decelerate, or turn the
steering wheel.
•You drive on snowy or slippery roads.
•Snow chains* are used.

Driving
You must start TPMS calibration every time you:
• Adjust the pressure in one or more tires.
• Rotate the tires.
• Replace one or more tires.
Before calibrating the TPMS:
• Set the cold tire pressu re in all four tires.
2Checking Tires P. 646
Make sure:
•The vehicle is at a complete stop.
• The transmission is in neutral.
• The transmission is in

• The power mode is in ON.
■TPMS Calibration1Tire Pressure Monitoring System (TPMS)
The low tire pressure/TPMS indicator may come on
under the following conditions:
•A compact spare tire is used.
•There is a heavier and une ven load on the tires,
such as when towing a trailer*, than the condition
at calibration.
•Snow chains* are used.
The Vehicle Stability Assist
TM (VSA ®) system, Vehicle
Stability AssistTM (VSA ®) OFF, adaptive cruise control
(ACC) with Low Speed Follow*, adaptive cruise control
(ACC)*, safety support and lo w tire pressure/TPMS
indicators may come on in amber along with a message
in the driver information interface when you set the
power mode to ON after reconnecting the battery.
Drive a short distance at mo re than 12 mph (20 km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.
1 TPMS Calibration
TPMS cannot be calibrated if a compact spare tire is
installed.
The calibration process requires approximately 30
minutes of cumulative driv ing at speeds between 30-
60 mph (48-97 km/h).
During this period, if the pow er mode is set to ON and
the vehicle is not moved wi thin 45 seconds, you may
notice the low tire pressu re/TPMS indicator comes on
briefly. This is normal and indicates that the calibration
process is not yet complete.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Depress the brake
pedal and keep holding the pedal firmly do wn. On dry pavement, you will need to
press on the brake pedal very hard before th e ABS activates. However, you may feel
the ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system. While normal
braking will not be affected, there is a possibility that
the ABS will not be opera ting. Have your vehicle
checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with snow chains*.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while the vehicle
accelerates.
•Brake pedal and/or the vehicle body vibration when
ABS activates.
These vibrations and sounds are normal to ABS
systems and are no cause for concern.
