If the cap is not tightened enough,
Check Engine “” indicator may

Smart Key system
NOTE: The Smart Key must be carried to enable the start function. With the
gear shift lever in Park and the brake pedal depressed, push the “ENGINE
START STOP” switch.
Without depressing the brake pedal, pressing the “ENGINE START STOP” switch
will change the operation mode in succession from:
Off - All systems OFF. Emergency flashers can be used.
Accessory – Some electrical components can be used.
On - All electrical components can be used.
START FUNCTION
POWER (WITHOUT STARTING ENGINE)

FEATURES & OPERATIONS
Shift the shift lever to “S” position from “D” position.
Floor shift type:
+ : Upshift (push and release)
- : Downshift (pull and release)
Column shift type:
+ : Upshift (push and release)
- : Downshift (push and release)
Downshifting increases power going uphill, or provides engine braking downhill. For
best fuel economy during normal driving conditions, always drive with the shift lever
in the “D” position.
* The engine switch must be in the “ON” position (without Smart Key)/“IGNITION
ON” mode (with Smart Key) and the brake pedal depressed to shift from Park.

FEATURES & OPERATIONS
Push and turnTurn
Shifting between “2WD” and “4H”
Reduce speed to less than 62 mph, then turn control to “2WD” or “4H.”
Shifting between “4H” and “4L”
When stopped shift to “N” position, then push and turn to “4L” from “4H.”
NOTE: For best fuel economy and performance under normal driving
conditions, keep in “2WD” position.
2WDHigh speed (2WD) Normal driving on dry hard-surfaced roads.
4HHigh speed (4WD) For driving only on roads that permit the tires to
slide, like off-road, icy or snow-covered roads.
4L
Low speed (4WD)
For maximum power and traction when climbing or descending steep
hills, off-road driving, and hard pulling in sand, mud or deep snow.
Turn
Two & four-wheel drive selector (if equipped)
The trailer brakes can be controlled by the Trailer brake controller via the 7-pin
connector. By selecting the type of brakes that are being used on the trailer
(electric or electric-over-hydraulic) and setting the gain for the controller, the
manual TRAILER BRAKE OUTPUT slider is used to slow just the trailer. The vehicle
brake pedal will also slow down as well as stop the trailer when applied. Gain
values, manual brake outputs, trailer brake types and the trailer connection status
are displayed in the multi-information display.
Refer to the Owner’s Manual for more details.

TOW/HAUL switch (if equipped)
“Tow/Haul” mode is ideal for use when carrying heavy loads. When the TOW/HAUL
switch is pressed, throttle response and transmission control are optimized for the
high performance operation. As fuel economy is reduced while in “Tow/Haul” mode,
deactivating when driving without a load is recommended.
• Upshifts occur at higher engine speeds to expand the use of lower gear
ranges, enhancing power performance during towing and preventing
repeated gear changes.
• Downshifts occur at a greater accelerator pedal angle to allow the
vehicle to stay in a higher gear, reducing repeated gear changes.
• Downshifts occur at a lower accelerator pedal angle to allow the
vehicle to stay in a lower gear, enhancing towing ability.
• When the accelerator pedal is wide open, upshift timing is optimized to
effectively use the maximum engine power range available.
When Tow/Haul is engaged, the opening angle of the electronically
controlled throttle is wider for any given accelerator pedal position than
normal, enhancing acceleration feeling and response.
• During uphill driving, the gear position is held to prevent repeated upshifting.
• During downhill driving, downshifting to lower gears will occur to effectively use
engine braking.
Refer to the Owner‘s Manual for more details on this system before attempting to
use it.
