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 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
”
in the owner's manual
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.
Vehicle Load Limits
It is very important to know how much
weight the vehicle can carry. This
weight is called the vehicle capacity
weight and includes the weight of all
occupants, cargo, and all
nonfactory-installed options. Two labels
on the vehicle may show how much
weight it was designed to carry: the
Tire and Loading Information label and
the Certification/Tire label.
{
Warning
Do not load the vehicle any heavier
than the Gross Vehicle Weight Rating
(GVWR), or either the maximum
front or rear Gross Axle Weight
Rating (GAWR). This can cause
systems to break and change the
way the vehicle handles. This could
cause loss of control and a crash.
Overloading can also reduce stopping
performance, damage the tires, and
shorten the life of the vehicle.
