The gearshift lever is designed so that it cannot be shifted out of "P" position unless the ignition switch is in "ON" position and the brake pedal is depressed.
Use the gearshift lever positions as fol­lows:
P (Park) Use this position to lock the transmission when the vehicle is parked or when start­ing the engine. Shift into Park only when the vehicle is completely stationary.
R (Reverse) Use this position to reverse the vehicle from stop. Make sure that vehicle is corn-
pletely stationary before shifting into Reverse.
N (Neutral) Use this position for starting the engine if the engine stalls and you need to restart it while the vehicle is moving. You may also shift into Neutral and depress the brake pedal to hold the vehicle stationary during
idling.
D (Drive) Use this position for all normal driving.
With the gearshift lever in "D" range you ?an get an automatic downshift by press­ing the accelerator pedal. The higher the vehicle speed is, the more you need to press the accelerator pedal to get a down­shift.
2 (Low2) Use this position to provide extra power when climbing hills, or to provide engine braking when going down hills.
L (Low 1) Use this position to provide maximum power when climbing steep hills or driving through deep snow or mud, or to provide maximum engine braking when going down steep hills.
OPERATING YOUR VEHICLE
A, WARNING
Always depress the brake pedal before shifting from "P" (Park) (or "N" (Neutral) if the vehicle is station­ary) to a forward or reverse gear, to help prevent the vehicle from moving unexpectedly when you shift.

Gearshift indicator
(if equipped)
52RM30410
In the following cases, the gearshift indica­tor is indicated in the information display when the ignition switch is in "ON" position. • When the gearshift lever is in a position other than "N" (Neutral). When the transfer lever is in "2H" or "4H" position. For vehicles equipped with the cruise control, when the system is not in use.

The electronic control system monitors driving condition (such as vehicle speed and/or engine revolution), and it shows which gear position is optimal for your driv­ing with the indication on the display.
If UP/DOWN arrow is indicated in the dis­play while driving, we recommend you to shift up or down the gear. It is the optimal gear position for a driving condition that reduces the over revolution and stress to the engine, and improves fuel consump­tion.
For details on how to use the transmission, refer to "Using the transmission" in this sec­tion.
A WARNING
The gearshift indicator is designed to indicate optimal gear position for your driving, however, a driver will not be relieved from the duty of care of driving operation or gear change with this indicator. To drive safe, do not gaze the gear­shift indicator, pay attention to your driving situation and shift up or down if necessary.
NOTE: The gearshift indicator is not indicated when the gear position is in "N" (Neu­tral). If you depress the clutch pedal while UPI DOWN arrow is indicated, the indication will disappear. In ordinary driving, UP arrow will disap­pear when you release your foot from the accelerator pedal. The indication of gearshift indicator tim­ing may differ depending on the vehicle condition and/or driving situation even in the same vehicle speed and engine rev­
olution. If any of the electrical systems such as dual sensor brake support system, or ESP" system is working, the gearshift indicator will disappear temporarily.

Transfer lever
(1) Transfer lever
Your vehicle is equipped with the "ALL GRIP PRO" system that consists of a transfer case with a synchronizer (between 2WD-high and 4WD-high positions) and the air locking hubs. With this feature, you can shift the drive mode between 2-wheel drive high range and 4-wheel drive high range by shifting the "2H" or "4H" position. Stop the vehicle or reduce the speed to less than 100 km/h (60 mph) with the front wheels in the straight ahead position. Do not shift the transfer lever without depress­ing the accelerator pedal. Do not activate the cruise control system when shifting the transfer lever.

NOTE: The air locking hubs are activated by the vacuum of the engine and changed to shift the front wheel drive. The air lock­ing hubs are not shifted when the engine is stopping. Several seconds are required from the operation of the trans­fer lever to the activation of air locking hubs. When the front tyres receive a big shock during running in 2-whee/ drive position on the road surface of the big irregularity, etc, some noise may occur inside the air locking hubs afterwards. In this situation, stop the vehicle and then shift the trans­fer lever into "4H" position. After that, shift the transfer lever into "2H" position
again.

NOTICE
• Never operate your vehicle in 114H" or 114L" on dry pavement and, as much as possible, avoid using "4H" or "4L" on wet pavement, as this may seriously damage the drive train.
• If the transfer lever is returned to the original position while shifting the transfer lever, the drive train may be damaged . . When you turn suddenly on a sharp curve, a side road, or a parking space in "4H" or 114L" position, the turning strength of the steering wheel will be growing big and tight corner braking phenomenon• may occur and result in accidents. 4-wheel drive system damage could also result.
''Tight corner braking phenomenon is the similar situation to depress the brake when the drive train is in 4-wheel drive position ("4H" or "4L") and the steering wheel is turned suddenly and then the revolution difference between the front wheels and the rear wheels could not absorb.

NOTICE
Pay attention to shifting the transfer lever safely when driving your vehi­cle.
NOTE: After shifting the transfer lever from "2H'" to "4H", check that the 4WD indicator
light comes on. After shifting the transfer lever from "4H" to "2H", check that the 4WD indicator goes off. ·
When 4WD indicator fight is blinking after shifting the transfer fever to "4H" position, accelerate, slow down your vehicle or stop and reverse your vehicle a little to shift the transfer lever. Pay attention to the vehicles and the circum­ference toward or backward your vehicle when shifting the transfer fever. When you shift the transfer fever while turning the steering wheel or depressing the accelerator pedal, shifting the trans­fer fever may be difficult. Operate the transfer fever while driving at low speed if it may be difficult to shift the transfer fever from "2H" position to "4H" position when the vehicle is stopped.
Shift the transfer fever again after decel­erating or stopping the vehicle if it may be difficult to shift the transfer fever from "2H" position to "4H" position while driv­ing or when the gear noise occurs. There may be a case to operate the transfer fever heavily when shifting the transfer lever from "4H" position to "2H" P_Osition while driving. In this case, posi­tion the front wheels straight ahead and drive for a while and then operate shift­ing the transfer fever again. When the transfer lever is shifted from 2H" position to "4H" position or from "4H" position to 2H" position and the air lock­ing hubs are activated, the air condition­ing system may not be operated for several seconds. This is not a malfunc­tion. When the ignition switch is turned "ON" after the transfer fever is shifted from 2H" position to "4H" position or from "4H" position to 2H" position while stopping the engine, 4WD indicator light may blink. This is not a malfunction.
OPERATING YOUR VEHICLE
