■Shift ranges and their functions
●You can choose from 8 levels (GS460) or 6 levels (GS350) of
engine braking force.
● A lower shift range will provide greater engine braking force than a
higher shift range, and the engine revolutions will also increase.
● If you accelerate while in ranges “1” to “7” (GS460) or “1” to “5”
(GS350), the shift range may automatically range up in accordance
with the vehicle’s speed.
● A higher shift range is automatically selected when the automatic
transmission fluid temperature is high.
■“S” mode
●When the shift range is “6” (GS460) or “4” (GS350) or lower, holding the shift
lever toward “+” sets the shift range to “8” (GS460) or “6” (GS350).
●To prevent the engine from over-revving, upshifting may automatically occur.
■Downshifting restrictions warning buzzer (in the “S” mode)
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever is operated. (The warning buzzer will sound twice.)
■When driving with the cruise control syst em (or dynamic radar cruise control sys-
tem)
The engine brake will not operate in the “S” mode, even when downshifting to “7”,
“6”, “5” or “4” (GS460) or “5” or “4” (GS350). ( →P. 165, 169)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP” switch is
turned to ACCESSORY or IGNITION ON mode after driving in snow mode.
■If the shift lever cannot be shifted from “P”

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
■ Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Remove any ice that has accumulated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow that
may have accumulated in the wheel well or on the brakes.
