the road. Learn to recognize
warning clues—such as
enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any
doubt.
.Try to avoid sudden
steering, acceleration,
or braking, including
reducing vehicle speed by
shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes
help avoid only the
braking skid.
Driving on Wet Roads
Rain and wet roads can
reduce vehicle traction and
affect your ability to stop and
accelerate. Always drive
slower in these types of
driving conditions and avoid
driving through large puddles
and deep-standing or flowing
water.
{Warning
Wet brakes can cause
crashes. They might not
work as well in a quick stop
and could cause pulling to
one side. You could lose
control of the vehicle.
After driving through a large
puddle of water or a car/
vehicle wash, lightly apply
the brake pedal until the
brakes work normally.
Flowing or rushing water
creates strong forces.
Driving through flowing
water could cause the
vehicle to be carried away.
If this happens, you and
other vehicle occupants
could drown. Do not ignore
police warnings and be very
cautious about trying to
drive through flowing water.
Hydroplaning
Hydroplaning is dangerous.
Water can build up under the
vehicle's tires so they actually
ride on the water. This can
happen if the road is wet
enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule
about hydroplaning. The best
advice is to slow down when
the road is wet.
Other Rainy Weather Tips
Besides slowing down, other
wet weather driving tips
include:
.Allow extra following
distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer
fluid reservoir filled.
.Have good tires with proper
tread depth. See Tires 0334.

200 Driving and Operating
.Turn off cruise control.
Hill and Mountain
Roads
{Warning
Do not charge your vehicle’s
battery above an 80%
charge if you are going to
drive down long, steep
grades such as mountain
passes. This provides room
in the battery for
regenerative braking to
supplement your
conventional brakes during
the descent. This is
especially important when
towing a trailer, which puts
additional stress on your
vehicle’s braking system.
If the battery becomes full,
regenerative braking will be
limited or unavailable. The
brakes will have to do all the
work of slowing down the
vehicle and could become(Continued)
Warning (Continued)
too hot. Hot brakes may not
be able to slow the vehicle
enough to maintain speed
and control. To help avoid
the risk of a crash, limit the
battery’s charge and, if you
experience brake fade or
receive a brake warning,
stop the vehicle and allow
the brakes to cool.
See“Charge Now” under
Charging 0123 for
information on setting
charge limits.
Driving on steep hills or
through mountains is different
than driving on flat or rolling
terrain. Be sure to:
.Use regenerative braking to
help slow the vehicle or
maintain speed by keeping
the vehicle in gear and
limiting the initial battery
charge to 80% or less.
.When braking is necessary,
use frequent, light taps of
the brake pedal. This
maximizes regenerative
braking and minimizes the
load on the vehicle brake
system.
.Keep the vehicle serviced
and in good shape.
.Check all fluid levels, brakes,
tires and cooling system.
.Drive at speeds that keep
the vehicle in its own lane.
Do not swing wide or cross
the center line.
.Be alert on top of hills;
something could be in your
lane (e.g., stalled car, crash).
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.

216 Driving and Operating
Brakes
Electric Brake Boost
Vehicles equipped with
electric brake boost have
hydraulic brake circuits that
are electronically controlled
when the brake pedal is
applied during normal
operation. The system
performs routine tests and
turns off within a few minutes
after the vehicle is turned off.
Noise may be heard during
this time. If the brake pedal is
pressed during the tests or
when the electric brake boost
system is off, a noticeable
change in pedal force and
travel may be felt. This is
normal.
Antilock Brake
System (ABS)
The Antilock Brake System
(ABS) helps prevent a braking
skid and maintain steering
while braking hard.
ABS performs a system check
when the vehicle is first driven.
A momentary motor or clicking
noise may be heard while this
test is going on, and the brake
pedal may move slightly. This
is normal.
If there is a problem with ABS,
this warning light stays on.
See Antilock Brake System
(ABS) Warning Light0117. ABS does not change the time
needed to get a foot on the
brake pedal and does not
always decrease stopping
distance. If you get too close
to the vehicle ahead, there will
not be enough time to apply
the brakes if that vehicle
suddenly slows or stops.
Always leave enough room
ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just
hold the brake pedal down
firmly. Hearing or feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and
braking at the same time. In
many emergencies, steering
can help even more than
braking.

Electric Parking Brake
The Electric Parking Brake
(EPB) can always be applied,
even if the vehicle is off. In
case of insufficient electrical
power, the EPB cannot be
applied or released. To
prevent draining the battery,
avoid unnecessary repeated
cycles of the EPB.
The system has a red parking
brake status light and an
amber service parking brake
warning light. See Electric
Parking Brake Light0116 and Service Electric Parking Brake
Light
0116. There are also
parking brake-related Driver
Information Center (DIC)
messages.
Before leaving the vehicle,
check the red parking brake
status light to ensure that the
parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The red parking brake status
light will flash and then stay on
once the EPB is fully applied.
If the red parking brake status
light flashes continuously, then
the EPB is only partially
applied or there is a problem
with the EPB. A DIC message
will display. Release the EPB
and try to apply it again. If the
light does not come on,
or keeps flashing, have the
vehicle serviced. Do not drive the vehicle if the red parking
brake status light is flashing,
see your dealer.
If the amber service parking
brake warning light is on,
press the EPB switch.
Continue to hold the switch
until the red parking brake
status light remains on. If the
amber service parking brake
warning light is on, see your
dealer.
If the EPB is applied while the
vehicle is moving, the vehicle
will decelerate as long as the
switch is pressed. If the switch
is pressed until the vehicle
comes to a stop, the EPB will
remain applied.
The vehicle may automatically
apply the EPB in some
situations when the vehicle is
not moving. This is normal, and
is done to periodically check
the correct operation of the
EPB system, or at the request
of other safety functions that
utilize the EPB.

the rear wheels to prevent
vehicle movement.
EPB Release
To release the EPB:1. Turn the vehicle on.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
red parking brake status light
is off.
If the amber service parking
brake warning light is on,
release the EPB by pressing
and holding the EPB switch.
Continue to hold the switch
until the red parking brake
status light is off. If either light
stays on after release is
attempted, see your dealer.
Caution
Driving with the parking
brake on can overheat the
brake system and cause
premature wear or damage
to brake system parts. Make
sure that the parking brake
is fully released and the
brake warning light is off
before driving.
Automatic EPB Release
The EPB will automatically
release if the vehicle is
running, placed into gear, and
an attempt is made to drive
away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake
lining life.
Brake Assist
Brake Assist detects rapid
brake pedal applications due
to emergency braking
situations and provides
additional braking to activate
the Antilock Brake System (ABS) if the brake pedal is not
pushed hard enough to
activate ABS normally. Minor
noise, brake pedal pulsation,
and/or pedal movement during
this time may occur. Continue
to apply the brake pedal as
the driving situation dictates.
Brake Assist disengages when
the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA
feature. HSA does not
replace the need to pay
attention and drive safely.
You may not hear or feel
alerts or warnings provided
by this system. Failure to
use proper care when
driving may result in injury,
death, or vehicle damage.
See Defensive Driving
0196.
When the vehicle is stopped
on a grade, Hill Start Assist
(HSA) prevents the vehicle

direction during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
The brakes may also release
under other conditions. Do not
rely on HSA to hold the
vehicle.
HSA is available when the
vehicle is facing uphill in a
forward gear, or when facing
downhill in R (Reverse). The
vehicle must come to a
complete stop on a grade for
HSA to activate.Automatic Vehicle
