2024 Toyota Grand Highlander
If a car of such like were to be made available, it might be thought of as a continuation of the Highlander line, with perhaps greater room, luxury, and cutting-edge technology. Targeting larger families or those looking for a more roomy and luxury SUV experience, the fictitious 2024 Toyota Grand Highlander might combine the comfort and modern technology that Toyota is recognized for with the dependability and efficiency that Toyota is known for. It would probably have a sleek, contemporary appearance, a variety of engine choices, including hybrid technology, and an emphasis on offering a connected and comfortable driving experience.
Connecting trailer lights (if equipped)
Use the wire harness stored in the rear end under the body.
Auto current cut-off function
In case of overcurrent, the auto cut-off function stops the power flowing to the trailer lights to prevent damage to the vehicle’s electrical system.
This function is activated when the rated current of any of the following trailer light circuit components is exceeded:
- Tail lights: maximum 8.0 A
- Stop/turn signal light (right): maximum 5.0 A
- Stop/turn signal light (left): maximum 5.0 A
When the auto current cut function is activated If a trailer light does not come on due to the activation of the auto current cut function, the light system will need to be reset.
Follow the reset procedure shown below.
-
If a tail light does not come on, turn off the headlight switch.
-
If the right-side stop/turn signal light does not come on, put the turn signal in the off position or remove the foot from the brake pedal.
-
If the left-side stop/turn signal light does not come on, put the turn signal in the off position or remove the foot from the brake pedal.
If the emergency flashers do not operate, press the emergency flasher switch to turn them off. After the light system is reset, oper-ate the light switches again to see if the lights operate normally. If the lights do not operate normally, have the vehicle inspected by your Toyota dealer.
Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage your vehicle’s electrical system and cause a malfunction.
Trailer towing tips
Your vehicle will handle differently when towing a trailer. Help to avoid an accident, death or serious injury, keep the following in mind when towing:
-
Speed limits for towing a trailer vary by state or province. Do not exceed the posted towing speed limit.
-
Toyota recommends that the vehicle-trailer speed limit is 65 mph (104 km/h) on a flat, straight, dry road. Do not exceed this limit, the posted towing speed limit or the speed limit for your trailer as outlined in your trailer owner’s manual, whichever is lowest. The instability of the towing vehicle-trailer combination (trailer sway) increases as speed increases. Exceeding speed limits may cause loss of con-trol.
- Before starting out, check the trailer lights, tires and vehicle-trailer connections. Recheck after driving a short distance.
- Practice turning, stopping and reversing with the trailer attached in an area away from traffic until you become accustomed to the feel of the vehicle-trailer combination.
- Reversing with a trailer attached is difficult and requires practice. Grip the bottom of the steering wheel and move your hand to the left to move the trailer to the left. Move your hand to the right to move the trailer to the right. (This is generally opposite to reversing without a trailer attached.) Avoid sharp or prolonged turning. Have someone guide you when reversing to reduce the risk of an accident.
-
As stopping distance is increased when towing a trailer, vehicle-to-vehicle distance should be increased. For each 10 mph (16 km/h) speed, allow at least one vehicle and trailer length.
-
Avoid sudden braking as you may skid, resulting in the trailer jackknifing and a loss of vehicle control. This is especially true on wet or slippery surfaces.
-
Avoid jerky starts or sudden acceleration.
-
Avoid jerky steering and sharp turns, and slow down before making a turn.
-
Note that when making a turn, the trailer wheels will be closer than the vehicle wheels to the inside of the turn. Compensate by making a wider-than-normal turning radius.
-
Slow down before making a turn, in cross winds, on wet or slippery surfaces, etc. Increasing vehicle speed can destabilize the trailer.
-
Take care when passing other vehicles. Passing requires considerable distance. After passing a vehicle, do not forget the length of your trailer, and be sure you have plenty of room before changing lanes.
-
To maintain engine braking efficiency and charging system performance when using engine braking, do not put the transmission in D.
If in the M mode, the transmission shift range position must be in 6 or lower.
- Instability happens more frequently when descending steep or long downhill grades. Before descending, slow down and downshift. Do not make sudden downshifts while descending steep or long downhill grades.
-
Avoid holding the brake pedal down too long or applying the brakes too frequently. This could cause the brakes to overheat and result in reduced braking efficiency.
-
Due to the added load of the trailer, your vehicle’s engine may overheat on hot days (at temperatures over 85°F [30°C]) when driving up a long or steep grade. If the engine coolant temperature gauge indicates overheating, immediately turn off the air conditioning (if in use), pull your vehicle off the road and stop in a safe spot.
-
Always place wheel blocks under both the vehicle’s and the trailer’s wheels when parking. Put the transmission in P and apply the parking brake.
- Apply the brakes and keep them applied.
- Have someone place wheel blocks under both the vehicle’s and trailer’s wheels.
- When the wheel blocks are in place, release the brakes slowly until the blocks absorb the load.
- Shift into P and apply the parking brake.
- Turn off the engine.
When restarting after parking on a slope:
- With the transmission in P, start the engine. Be sure to keep the brake pedal depressed.
- Shift into a forward gear. If reversing, shift into R.
- If the parking brake is in manual mode, release the parking brake.
- Release the brake pedal, and slowly pull or back away from the wheel blocks. Stop and apply the brakes.
- Have someone retrieve the blocks.
Engine switch illumination
According to the situation, the engine switch illumination operates as follows.
-
When a door is opened, or the engine switch is changed from ACC or ON to off, the engine switch illumination illuminates.
-
When depressing the brake pedal while carrying the electronic key on your person, the engine switch illumination blinks.
-
When the engine switch is in ACC or ON, the engine switch illumination illuminates.
If the engine does not start
-
The engine immobilizer system may not have been deactivated. Contact your Toyota dealer.
-
If a message related to start-up is shown on the multi-information display, read the message and follow the instructions.
-
If the door is unlocked with the mechanical key, the engine cannot be started using the smart key system. to start the engine. However, if the electronic key is carried inside the vehicle and the doors are locked the engine can be started.
Automatic engine shut off feature
-
The vehicle is equipped with a feature that automatically shuts off the engine when the shift position is in P with the engine running for an extended period.
-
The engine will automatically shut off after approximately 1 hour if it has been left running while the shift position is in P.
-
The timer for the automatic engine shut-off feature will reset if the brake pedal is depressed, or if the shift position is in a position other than P.
- After the vehicle is parked, if the door is locked with the door lock switch from the inside or the mechanical key from the outside, the automatic engine shut-off feature will be disabled. The timer for the automatic engine shut-off feature will be re-enabled if the driver’s door is opened.
When the engine is stopped
Even if the engine switch is turned off, the cooling fan may continue to operate for a short time.
WARNING
Stopping the engine in an emergency
-
If you want to stop the engine in an emergency while driving the vehicle, press and hold the engine switch for more than 2 seconds, or press it briefly 3 times or more in succession. However, do not touch the engine switch while driving except in an emergency.
-
Turning the engine off while driving will not cause a loss of steering or braking control, but the power assist to these systems will be lost.
-
This will make it more difficult to steer and brake, so you should pull over and stop the vehicle as soon as it is safe to do so.
-
If the engine switch is operated while the vehicle is running, a warning message will be shown on the multi-information display and a buzzer will sound.
- To restart the engine after performing an emergency shut-down, shift the shift lever to N and then press the engine switch.
When parking
Exhaust gases include harmful carbon monoxide (CO), which is colourless and odourless. Observe the following precautions. Failure to do so may cause exhaust gases to enter the vehicle and may lead to an accident caused by light-headedness, or may lead to death or a serious health hazard.
-
If the vehicle is in a poorly venti-lated area or a closed area, such as a garage, stop the engine.
-
Do not leave the vehicle with the engine running for a long time. If such a situation cannot be avoided, park the vehicle in an open space and ensure that exhaust fumes do not enter the vehicle’s interior.
-
Do not leave the engine running in an area with snow build-up, or where it is snowing. If snow-banks build up around the vehi-cle while the engine is running, exhaust gases may collect and enter the vehicle.
Changing engine switch modes
Modes can be changed by pressing the engine switch with the brake pedal released. (The mode changes each time the switch is pressed.)
Auto power off function
If the vehicle is left in ACC or ON (the engine is not running) for more than 20 minutes with the shift lever is in P or the shift release button is not pressed, the engine switch will automatically turn to OFF. However, this function cannot entirely prevent battery discharge. Do not leave the vehicle with the engine switch in ACC or ON for long periods when the engine is not running.
When ACC customization is in the off
-
With the engine switch turned off, the Multimedia Display can still be used for a certain time until the battery-saving function starts operating.
-
When the safe exit assist is operating, a buzzer will sound and voice guidance will be given.
To prevent battery discharge
-
Do not leave the engine switch in ACC or ON for long periods without the engine running.
-
If “ACCESSORY” or “POWER ON” is displayed on the meters while the engine is not running, the engine switch is not off. Exit the vehicle after turning the engine switch off.
When stopping the engine with the shift position in a position other than P
If the engine is stopped when the shift lever is in a position other than P or the shift release button is pressed, the engine switch will not be turned off but instead be turned to ACC.
Perform the following procedure to turn the switch off:
- Check that the parking brake is set.
- Shift the shift lever to P. Do not press the shift release button after shifting the shift position to P.
- Check that “POWER ON” is displayed on the multi-infor-mation display and press the engine switch shortly and firmly.
- Check that “ACCESSORY” or “POWER ON” on the multi-information display are off.
To prevent battery discharge
Do not stop the engine with the shift lever in a position other than P or the shift release button pressed. If the engine is stopped with the shift lever in a position other than P or the shift release button pressed, the engine switch will not be turned off and remain ON. If the vehicle is left in ON, battery discharge may occur.
To protect the automatic transmission
If the automatic transmission fluid temperature is high, “Transmission Oil Temp High Stop in a Safe Place and See Owner’s Manual” will be displayed on the multi-information display and the vehicle will go into transmission protection mode automatically. Have the vehicle inspected by your Toyota dealer.
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 be activated because dynamic radar cruise control will not be cancelled.
-
Vehicles with paddle shift switches: While driving in the D position, downshift to D5 or D4.
-
When switching the driving mode to sport mode while driving in the D position
Sudden start restraint control (Drive-Start Control [DSC])
AI-SHIFT
The AI-SHIFT automatically selects the suitable gear according to driver performance and driving conditions. The AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever to the M position cancels the function.)
