{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.
See Hill and Mountain Roads
0200 for important
information about driving on
grades.
The default charge level is
100% when plugged in. To set
a different charge level, drag
the circular marker on the
Target Charge Level Gauge to
the preferred value. To lower
the desired Charge Level, drag the Charge Level marker
counterclockwise, and to
increase it drag the marker
clockwise. The Charge Level
can also be changed by
tapping
«andªinside the
gauge on the screen. The
multifunction controller (MCF)
on the center console can also
be used to set the Charge
Level by rotating clockwise or
counterclockwise when the
Target Charge Level Gauge is
highlighted. The Range
estimate updates once the
desired Charge Level is set.
To optimize battery health, the
minimum allowable Charge
Level is determined by the
vehicle. Charge Later
Instead of charging
immediately to a desired
Charge Level, you may choose
to delay the charge to the
vehicle and have it complete
by your desired departure
time. This may be a more
economical choice and a more
efficient use of energy when
charging at home. To use this
mode, touch the Charge Later
tab from the Charging screen.
With Charge Later selected,
the Charging screen displays:
.Text explaining that your
vehicle will delay the planned
charge to be ready by the
time specified.

reduces glare caused by
reflecting of wet roads.Maneuvering Light

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.
