GX460_OM_OM60T19U_(U)4-2. Driving procedures
■Driving on a downhill
On declines, there may be case where the ve
hicle shifts down automatically to obtain
engine braking. As a result of the down shifting, the engine speed may increase.
■Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in
second start mode.
■S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift range to
6.
■AI-SHIFT
AI-SHIFT automatically shifts the gear to the suitable position according to driver perfor-
mance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position. (Shifting the
shift lever to the S position cancels the function.)
■When driving with dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because dy namic radar cruise control will not be can-
celed.
●While driving in S mode, downshifting to 5 or 4. ( P. 258)
●Vehicles with adaptive variable suspensi on system: When switching the driving mode
to sport mode while driving in D position. ( P. 343)
■Restraining sudden start (Drive-Start Control)
 P. 170
■Shift lock system
The shift lock system is a system to prevent ac cidental operation of the shift lever in start-
ing.
The shift lever can be shifted from P only when the engine switch is in the IGNITION ON
mode and the brake pedal is being depressed.

or turn the light switch to position once and then back to or .
If any of the doors or glass hatch is kept open, the lights automatically turn off after 20
minutes.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted accordi ng to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■Welcome lighting
If the headlight switch is turned to AUTO and the surrounding area is dark, unlocking the
doors using the smart access system with pu sh-button start or wireless remote control
will turn the parking lights and tail lights on automatically.
