Toyota Tundra Owners Manual: Automatic transmission

Shifting the shift lever

Floor shift type

Driving procedures

While the engine switch is in the "ON" position, move the shift lever with the brake pedal depressed.

When shifting the shift lever between P and D, make sure that the vehicle is completely stopped.

Column shift type

Driving procedures

While the engine switch is in the "ON" position, move the shift lever with the brake pedal depressed.

When shifting the shift lever between P and D, make sure that the vehicle is completely stopped.

Shift position purpose

Shift position Function
P Parking the vehicle/starting the engine
R Reversing
N Neutral (Condition in which the power is not transmitted)
D Normal driving*1
S S mode driving*2

*1: To improve fuel efficiency and reduce noises, set the shift lever in the D position for normal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of the possible gear ranges, controls engine braking forces, and prevents unnecessary upshifting.

Selecting shift ranges in the S position

To enter S mode, shift the shift lever to S. Shift ranges can be selected by operating the shift lever, allowing you to drive in the shift range of your choosing. The shift range can be selected by the shift lever.

Driving procedures

  1. Upshifting
  2. Downshifting

The selected shift range, from 1 to 6, will be displayed in the meter.

The initial shift range in S mode is set automatically to 5 or 4 according to vehicle speed. However, the initial shift range may be set to 3 or 2 if the AI-SHIFT has operated while the shift lever was in the D position.

■ Shift ranges and their functions

  • Automatically selecting gears between 1 and 6 according to vehicle speed and driving conditions.
  • You can choose from 6 levels of accelerating force and engine braking force.
  • A lower shift range will provide greater accelerating force and engine braking force than a higher shift range, and the engine revolutions will also increase.

TOW/HAUL switch (vehicles with towing package)

Use TOW/HAUL mode when pulling a trailer or hauling a heavy load.

Press the TOW/HAUL switch. The indicator will come on.

Press the switch once more to cancel the mode.

■AI-SHIFT AI-SHIFT automatically selects the suitable gear according to the driver performance 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 cruise control activated (if equipped) Even when performing the following actions with the intent of enabling engine braking, engine braking will not activate while driving in S mode and downshifting to 5 or 4 because cruise control will not be canceled.

■Shift lock system The shift lock system is a system to prevent accidental operation of the shift lever in starting.

The shift lever can be shifted from P only when the engine switch is in the "ON" position and the brake pedal is being depressed.

■If the shift lever cannot be shifted from P First, check whether the brake pedal is being depressed.

If the shift lever cannot be shifted with your foot on the brake pedal, there may be a problem with the shift lock system. Have the vehicle inspected by your Toyota dealer immediately.

The following steps may be used as an emergency measure to ensure that the shift lever can be shifted.

Releasing the shift lock:

1. Set the parking brake.

2. Turn the engine switch to the "LOCK" position.

3. Depress the brake pedal.

4. Pry the cover up with a flathead screwdriver or equivalent tool.

To prevent damage to the cover, cover the tip of the screwdriver with a rag.

■If the "S" indicator does not come on even after shifting the shift lever to S This may indicate a malfunction in the automatic transmission system. Have the vehicle inspected by your Toyota dealer, immediately.

(In this situation, the transmission will operate in the same manner as when the shift lever is in D.)

■Downshifting restrictions warning buzzer (S mode) To help ensure safety and driving performance, downshifting operation may sometimes be restricted. In some circumstances, downshifting may not be possible even when the shift lever is operated. (A buzzer will sound twice.)

■Transmission protection function If the tires spin continually when the vehicle becomes stuck in mud, dirt or snow, the automatic transmission temperature may become too high and cause damage.

To avoid the damaging the automatic transmission, the system may temporarily lock the gear in 1st.

If the automatic transmission temperature falls, the gear locking is canceled and returns the automatic transmission to the normal operation.

WARNING

■When driving on slippery road surfaces Do not accelerate or shift gears suddenly.

Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in an accident.

■To prevent an accident when releasing the shift lock Before pressing the shift lock override button, make sure to set the parking brake and depress the brake pedal.

If the accelerator pedal is accidentally depressed instead of the brake pedal when the shift lock override button is pressed and the shift lever is shifted out of P, the vehicle may suddenly start, possibly leading to an accident resulting in death or serious injury.
