On-board Diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects
the environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle.
When the service engine soon indicator illuminates, the OBD-II
system has detected a malfunction. Temporary malfunctions
may cause the service engine soon indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel fill inlet may not have been properly closed. SeeEasy Fuel®
No Cap Fuel Systemin this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly closing the fuel fill inlet or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon indicator
should stay off the next time the engine is started. A driving cycle
consists of a cold engine start-up followed by mixed city or highway
driving. No additional vehicle service is required.
If the service engine soon indicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the service engine soon indicator on can result
in increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and can lead to more costly repairs.

Readiness for Inspection/Maintenance (I/M) Testing
Some state, provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration.
If the service engine soon indicator is on or the bulb does not
work, the vehicle may need to be serviced. SeeOn-board
Diagnostics (OBD-II)in this chapter.
Your vehicle may not pass the I/M test if the service engine soon
indicator is on or not working properly (bulb is burned out), or if the
OBD-II system has determined that some of the emission control systems
have not been properly checked. In this case, the vehicle is considered
not ready for I/M testing.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine soon
indicator blinks eight times, it means that the vehicle is not ready for I/M
testing; if the service engine soon indicator stays on solid, it means that
the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway or highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle.
The engine must warm up to its normal operating temperature. Once the
engine is started, do not turn off the engine until the above driving cycle
is complete. If the vehicle is still not ready for I/M testing, the above
driving cycle will have to be repeated.

HILL START ASSIST
WARNING:The hill start assist feature does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and shift the transmission into P (Park).
WARNING:You must remain in the vehicle once you have
activated the hill start assist feature.
WARNING:During all times, you are responsible for controlling
the vehicle, supervising the hill start assist system and
intervening, if required.
WARNING:If the engine is revved excessively, or if a
malfunction is detected when the hill start assist feature is active,
the hill start assist feature will be deactivated.
Hill start assist keeps your vehicle stationary long enough to move your
foot from the brake pedal to the accelerator pedal when your vehicle is
on a slope.
The brakes are released automatically once the engine has developed
sufficient drive to prevent the vehicle from rolling down the slope. This
is an advantage when pulling away on a slope, (for example from a car
park ramp, traffic lights or when reversing uphill into a parking space).
Using Hill Start Assist
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, the hill start assist
feature will be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately two or three
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.

GENERAL INFORMATION
Note:Occasional brake noise is normal. If a metal-to-metal, continuous
grinding or continuous squeal sound is present, the brake linings may
be worn out and should be inspected by an authorized dealer. If your
vehicle has continuous vibration or shudder in the steering wheel while
braking, you should take it to an authorized dealer for inspection.
Note:Brake dust may accumulate on the wheels, even under normal
driving conditions. Some dust is inevitable as the brakes wear and does
not contribute to brake noise. See theVehicle Carechapter for wheel
cleaning instructions.
See theInstrument Clusterchapter for information on the
brake system warning light.
Wet brakes result in reduced braking efficiency. Gently press the brake
pedal a few times when driving from a car wash or standing water to dry
the brakes.
Brake Over Accelerator
If the accelerator pedal becomes stuck or entrapped, apply steady and
firm pressure to the brake pedal to slow your vehicle and reduce engine
power. If you experience this condition, apply the brakes and bring
your vehicle to a safe stop. Turn the engine off, shift to positionPand
apply the parking brake, then inspect the accelerator pedal for any
interferences. If none are found and the condition persists, have your
vehicle towed to the nearest authorized dealer.
Anti-Lock Brake System
This system helps you maintain steering control during emergency stops
by keeping the brakes from locking.
The anti-lock brake system lamp momentarily illuminates when
the ignition is turned on. If the light does not illuminate during
start-up, remains on or flashes, the anti-lock brake system may
be disabled and may need to be serviced.
If the anti-lock brake system is disabled, normal braking is still
effective. If the brake warning lamp illuminates with the parking
brake released, have your brake system serviced immediately.

Regenerative Braking System
This feature is used to simulate the engine braking of an internal
combustion engine and assist the standard brake system while recovering
some of the energy of motion and storing it in the battery to improve fuel
economy. The standard brake system is designed to fully stop the car if
regenerative braking is not available. During regenerative braking, the
motor is spun as a generator to create electrical current. This recharges
the battery and slows the vehicle. In effect, once the accelerator pedal is
released, the motor changes from an energy user to an energy producer.
When the accelerator pedal is released or the brake pedal is applied,
the brake controller automatically detects the amount of deceleration
requested and optimizes how much of the deceleration will be produced
by regenerative braking. The remaining portion is generated by standard
friction braking. When the battery is almost fully charged, the amount of
regenerative braking is limited to avoid overcharging, and the requested
deceleration is produced by standard friction braking alone.
Regenerative braking does not take the place of the standard friction
brakes; it only assists them. Regenerative braking has also been designed
to interact with the anti-lock brake system. Regenerative braking is
disabled when the anti-lock brake system is activated or the battery is
fully charged.
HINTS ON DRIVING WITH ANTI-LOCK BRAKES
When the system is operating, the brake pedal will pulse and may travel
further. Maintain pressure on the brake pedal. You may also hear a noise
from the system. This is normal.
The anti-lock braking system will not eliminate the dangers inherent when:
•you drive too closely to the vehicle in front of you.
•your vehicle is hydroplaning.
•you take corners too fast.
•the road surface is poor.
