Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during corn ering 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 outp ut 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
VSA® may not function properly if tire types and sizes
are mixed. Make sure to use the same size and type
of tire, and the air pressures are 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.

(RDM), Vehicle Stability Assist

Stability AssistTM (VSA ®) OFF, Low Tire Pressure/TPMS*
and Collision Mitigation Braking SystemTM (CMBSTM)
may come on after reconnect ing the battery. Drive a
short distance at more than 12 mph (20 km/h). The
indicators should go off. If they do not, have your
vehicle checked by a dealer.
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 alwa ys 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.

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.
U.S. models
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. 548
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.
The low tire pressure/TPMS indicator may come on
under the following conditions:
•A compact spare tire is used.•There is a heavier and uneve n load on the tires than
the condition at calibration.
•Snow chains are used.

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 pressure in all four tires.

do not, have your vehicl e checked by a dealer.
1TPMS 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-
65 mph (48-105 km/h).
During this period, if the i gnition switch is turned to
ON
( w*1 and the vehicle is not moved within 45
seconds, you may notice the low tire pressure indicator
comes on briefly. This is no rmal and indicates that the
calibration process is not yet complete.
If the snow chains are installed, remove them before
calibrating the TPMS.
If the low tire pressure/TPMS indicator comes on even
when the properly inflated specified regular tires are
installed, have your vehicle checked by a dealer.
We recommend that the tires be replaced with the
same brand, model, and size as the originals. Ask a
dealer for details.

Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation
Each tire, including the spare (i f provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire infl ation pressure label, you should
determine the proper tire inflat ion pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tire s is significantly under-inflated.
Accordingly, when the low tire pr essure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-in flated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread li fe, and may affect the vehicle's
handling and stopping ability.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver 's responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumination of th e TPMS low tire pressure telltale.
Your vehicle has also been equi pped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the syst em detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illumina ted. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
