2. Press the plus/minus button on the shift
lever, to increase or decrease the gear
range available.
When shifting to L(Manual Mode), the
transmission will shift to apreset lower gear
range. For this preset range, the highest gear
available is displayed next to the Lin the
DIC. See Driver Information Center (DIC) 397
for more information. All gears below that
number are available to use. For example,
when 4(Fourth) is shown next to the L,
1(First) through 4(Fourth) gears are shifted
automatically. To shift to 5(Fifth) gear, press
the +(Plus) button or shift into D(Drive).
L (Manual Mode) will prevent shifting to
a
lower gear range if the engine speed is too
high. If vehicle speed is not reduced within
the time allowed, the lower gear range shift
will not be completed. Slow the vehicle, then
press the − (Minus) button to the desired lower
gear range.
While using the ERS, cruise control can be used.
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 p
erforms 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
l
ight stays on. See Antilock Brake System (ABS)
Warning Light 391.
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.
