When Driving
Starting the Engine
1.Make sure the parking brake is applied.
2. Depress the brake pedal.
3. Press the ENGINE START/STOP button
without depressing the accelerator pedal.1 Starting 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 al titudes 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.
Bring the smart entry remote close to the ENGINE
START/STOP button if the battery in the smart entry
remote is weak. 2 If the Smart Entry Remote Battery is Weak
P. 692
The engine may not start if the smart entry remote is
subjected to strong radio waves.

When you change (D to (R and vice versa, depress
the brake pedal to come to a complete stop, then
select the intended gear position while maintaining
brake pressure.
Use the gear position indicator and the shift button
indicator to check the gear position before selecting
a shift button.
If the indicator of the currently selected gear position,
or all the gear position indicators are blinking
simultaneously, there is a problem with the
transmission.
Avoid sudden acceleration and have the transmission
checked by a dealer as soon as possible.
The fuel supply may be cut of f if you drive at engine
speeds in or over the tac hometer’s red zone (engine
speed limit). If this happe ns, you may experience a
slight jolt.
When the engine speed is increased while the
transmission is in

uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps reduce the effort needed on the brake pe dal. The brake assist system increases
the stopping force when you depress the brake pedal hard in an emergency
situation. The anti-lock brake system (ABS) helps you retain steering control when
braking very hard.

■Foot Brake1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by a deal er. If you hear only an
occasional squeak or squeal when you initially apply
the brake pedal, this may be normal and caused by
high frequency vibr ation of the brake pads against
the rotating brake disc.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal and downshifting to a
lower gear.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, a nd helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution 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 dow n. On dry pavement, you will need to
press on the brake pedal very hard before the ABS activates. However, you may feel
the ABS activate immediately if yo u are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 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 wi ll not be operating. 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.
