1Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to st art in cold weather and in
thinner air found at altit udes above 8,000 feet (2,400
meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system, and rear de fogger in order to reduce
battery drain.
If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. Cons ult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
The immobilizer system pr otects your vehicle from
theft. If an improperly c oded device is used, the
engine’s fuel system is disabled. 2 Immobilizer System P. 145

Precautions While Driving
Avoid driving in deep water and on flooded roads. This can damage the engine or
driveline, or cause elec trical component failure.
If there is a strong impact with something under the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
■In Rain
■Other Precautions
1 Precautions While Driving
NOTICE
Do not operate the shift lever while pressing the
accelerator pedal. You could damage the
transmission.
NOTICE
If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel in
the full left or right position for a while, the electric
power steering (EPS) system heats up. The system
goes into a protective mode, and limits its
performance. The steering wheel becomes harder
and harder to operate. Once the system cools down,
the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the ignition switch is turned to ACCESSORY
( q*1
while driving, the engine will shut down and all
steering and brake power a ssist functions will stop,
making it difficult to control the vehicle.
Do not select
( N while driving as you will lose engine
braking (and accelera tion) performance.
During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as not to damage the engine or powertrain.
Avoid hard braking for the first 200 miles (300 km).
You should also follow this when the brake pads are
replaced.

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.
The indicators for the Adap tive Cruise Control (ACC)
with Low Speed Follow, Roa d Departure Mitigation
(RDM), Vehicle Stability Assist
TM (VSA® ) system, Vehicle
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
This button is on the driv er side control panel.
To partially disable VSA ® functionality/
features, press and hold it until you hear a
beep.
Your vehicle will have normal braking and
cornering ability, but traction control function
will be less effective.
To restore VSA ® functionality/features, press
the (VSA ® OFF) button until you hear a
beep.
VSA ® is turned on every time you start the
engine, even if you turned it off the last time
you drove the vehicle.
■VSA ® On and Off1 Vehicle Stability AssistTM (VSA ®), aka Electronic Stability Control
(ESC), System
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the button is pressed, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA ® off if
you are not able to free it when the VSA ® is on.
Immediately after freeing your vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® system switched off.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.

uuWhen Driving uTire Pressure Monitoring System (TPMS)
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 pressure in all four tires.

mph (20 km/h). The indicators should go off. If they
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.
