Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid , remove ice once it has softened.
u When removing ice from around the wheels, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressures, and check for damage and excessive wear.

■Exterior Checks1Exterior Checks
NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you've parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also, check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.

uuWhen Driving uHill Descent Control System
Driving
Hill Descent Control System
When driving down hills where engine braking is not enough to decelerate the
vehicle, this system helps maintain a co nstant vehicle speed without needing to
depress the brake pedal.
The system operates under the following conditions.
• Driving at a speed between about 2-12 mph (3-20 km/h).
• Driving downhill.
• Accelerator pedal and brake pedal are not depressed.
The system’s operating status
•Green: Activated
• White: Standby
Vehicle speed display
• White: Set speed
• Grey: Current speed
u Blinks when the vehicle speed is above
the operating speed.
■Hill Descent Control Operating Conditions
■Driver Information Interface Display
1Hill Descent Control System
The brake lights automati cally come on while the
system is in operation.
The system may not operate when driving down a
gentle slope. Check the Hill Descent Control System
indicator to see if the system is in operation.
The system may activate even when not driving
downhill, such as when the vehicle leans while
driving over uneven surfaces.
3WARNING
Hill descent control cannot maintain a
constant vehicle speed in every situation.
When driving down a very steep hill or on
slippery road surfaces, the vehicle may not
be able to maintain the vehicle speed and
could cause a crash, resulting in serious
injury or death.
Since Hill Descent Control is not designed
to increase the limits of vehicle
performance, the driver must always be
aware of road surface conditions and drive
safely.

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 can.
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 incorrect 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 tire 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
power system has been turned on 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.
