Quick Reference Guide
VSA® On and Off (P 444)
●The Vehicle Stability AssistTM (VSA ®)
system helps stabilize the vehicle during
cornering, and helps maintain traction
while accelerating on loose or slippery
road surfaces.
●VSA ® comes on automatically every time
you start the engine.
●To partially disable or fully restore VSA ®
function, press and ho ld the button until
you hear a beep.
CMBSTM On and Off
(P 461)
●When a possible frontal collision is likely
unavoidable, the CMBSTM can help you to
reduce the vehicle speed and the severity
of the collision.
●The CMBSTM is turned on every time you
start the engine.
●To turn the CMBSTM on or off, use the
safety support switch.
Tire Pressure Monitoring
System (TPMS)
(P 446)
●Detects a change in tire conditions and
overall dimensions due to decrease in tire
pressures.
●The TPMS is turned on automatically
every time you start the engine.
●A calibration procedure must be
performed when certain conditions arise.

Quick Reference Guide
Pressing the electric
parking brake switch does
not release the parking
brake. Why?Press the electric parking brake switch with the brake pedal
depressed.
I’m seeing an amber
indicator of a tire with an
exclamation point. What is
that?The Tire Pressure Monitoring Syst em (TPMS) needs attention. If
you recently inflated or changed a tire, you have to recalibrate
the system.
2 Tire Pressure Monitoring System (TPMS) (P446)
Depressing the accelerator
pedal does not release the
parking brake
automatically. Why?●Fasten the driver’s seat belt.
●Check if the transmission is in (P or (N. If so, select any other
position.
Why does the shift position
automatically change to
(P
when I open the driver’s
door to check for parking
space lines when
reversing?
●Fasten the driver’s seat belt.
●Close the driver’s door and manually change the shift
position.
2 When opening the driver’s door (P424)
Why do I hear a screeching
sound when I apply the
brake pedal?The brake pads may need to be replaced. Have your vehicle
inspected by a dealer.

indicate the calibration process is
not yet complete.
●Comes on and stays on when:
-One or more tires’ pressures are
determined to be significantly low.
- The system has not been
calibrated.
●Comes on while driving - Stop in a safe
place, check tire pressures, and inflate the
tire(s) if necessary.
●Stays on after the ti res are inflated to
the recommended pressures - The
system needs to be calibrated.

●Blinks for about one minute, and
then stays on if there is a problem
with the TPMS, or when a compact
spare tire is temporarily installed.●Blinks and remains on - Have your vehicle
checked by a dealer. If the vehicle is fitted
with a compact spare tire, get your regular
tire repaired or replaced and put back on
your vehicle as soon as you can.
●Comes on if the TPMS is deactivated
temporarily after the battery has
been disconnected, then re-
connected.●Drive a short distance at more than 12 mph
(20 km/h). The indicator should go off. If it
does not, have your vehicle checked by a
dealer.

uuWhen Driving uVehicle Stability AssistTM (VSA ®), aka Electronic Stability Control (ESC), System
Continued
Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine ou tput and selectively applying the brakes.
When VSA ® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic brake system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability AssistTM (VSA® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.
The Vehicle Stability Assist
TM (VSA ®) system, Vehicle
Stability AssistTM (VSA ®) OFF, adaptive cruise control
(ACC) with Low Speed Follow, safety support and
low 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 more than 12 mph (20 km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.

uuWhen Driving uTire Pressure Monitoring System (TPMS)
Driving
Tire Pressure Monitoring System (TPMS)
Instead of directly measuring the pressu re 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. 577
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.
•Tire chains* are used.

Driving
1Tire 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.
•Tire chains* are used.
The Vehicle Stability Assist
TM (VSA ®) system, Vehicle
Stability AssistTM (VSA ®) OFF, adaptive cruise control
