Operating Your Vehicle
Familiarize yourself with the Highlander’s controls for optimal driving. This section details starting, driving modes, transmission, and essential operational procedures for safe use.
Starting and Stopping the Engine
Starting the Engine: Ensure the vehicle is in Park (P) or Neutral (N), and your foot is firmly on the brake pedal. Insert the key into the ignition or press the start button while depressing the brake. The engine will start; release the key or button once running. Avoid prolonged cranking.
Stopping the Engine: Gently apply the brakes to bring the vehicle to a complete stop. Shift the gear selector to Park (P). Turn the ignition key to the “LOCK” position or press the start/stop button to shut off the engine; Remove the key for security. Never turn off the engine while driving.
Important Note: Always allow the engine to idle for a short period before and after driving, especially in cold weather, to ensure proper lubrication and prevent engine damage.
Driving Modes (Normal, Sport, Eco)
Normal Mode: This is the standard driving mode, providing a balance between fuel efficiency and performance for everyday driving conditions. It’s suitable for most situations and offers a comfortable ride;
Sport Mode: Engaging Sport Mode enhances throttle response and steering feel, delivering a more dynamic and engaging driving experience. It prioritizes performance over fuel economy, ideal for spirited driving or merging onto highways.
Eco Mode: Eco Mode optimizes engine and transmission settings to maximize fuel efficiency. It reduces throttle sensitivity and adjusts shift points for smoother acceleration, promoting responsible driving habits.
Automatic Transmission Operation
Shifting Positions: Your Highlander’s automatic transmission features several positions – Park (P), Reverse (R), Neutral (N), and Drive (D). Always come to a complete stop before shifting between these positions. The ‘S’ position allows for manual-like shifting.
Drive (D): This is the primary driving position, automatically selecting the optimal gear for speed and load. The transmission will upshift and downshift as needed for efficient operation.
Overdrive: The transmission utilizes overdrive for improved fuel economy at highway speeds. Avoid using overdrive in hilly terrain or when towing. Proper maintenance, including fluid checks, is crucial for longevity.
Manual Shift Mode
Accessing Manual Mode: Shift the gear selector to the ‘S’ (Sport) position to engage manual shift mode. You can then manually select gears using the shift lever – pushing forward for upshifts and pulling backward for downshifts. The instrument panel displays the currently selected gear.
Upshifting & Downshifting: The transmission prevents shifts that could damage the engine or transmission. It will automatically downshift if the vehicle slows to a speed inappropriate for the selected gear.
Returning to Automatic: Simply move the shift lever back to the ‘D’ position to return to fully automatic operation. Regular transmission fluid checks are vital for optimal performance.
Safety Features
Your 2012 Highlander incorporates advanced safety systems like airbags, ABS, VSC, and TRAC, designed to protect you and your passengers during a collision.
Airbag System
The 2012 Toyota Highlander is equipped with a sophisticated airbag system designed to provide crucial protection in the event of a collision. This system includes driver and front passenger airbags, as well as side curtain airbags for both rows of seating.
These airbags are designed to deploy rapidly, cushioning occupants and reducing the risk of serious injury. It’s vital to understand that airbags are supplemental restraints and work best when used in conjunction with seatbelts.
Always ensure all passengers are properly restrained. Improper seating positions or modifications to the vehicle could affect airbag deployment and effectiveness. Refer to the full owner’s manual for detailed information regarding the airbag system and safety precautions;
Anti-lock Brake System (ABS)
Your 2012 Toyota Highlander features an Anti-lock Brake System (ABS) designed to help maintain steering control during hard braking situations and reduce the risk of wheel lockup. When ABS activates, you may feel a pulsing sensation in the brake pedal; this is normal operation.
Continue applying firm and steady pressure to the brake pedal during ABS activation. Do not pump the brakes, as this can reduce the system’s effectiveness. The ABS system works independently at each wheel, optimizing braking performance.
Regularly check the ABS warning light on the dashboard. If illuminated, it indicates a system malfunction requiring immediate attention from a qualified technician.
Vehicle Stability Control (VSC)
The 2012 Toyota Highlander is equipped with Vehicle Stability Control (VSC), a system designed to help prevent skidding and maintain directional control, especially during emergency maneuvers or on slippery surfaces. VSC utilizes sensors to detect loss of traction and automatically applies braking force to individual wheels.
A VSC indicator light on the dashboard will illuminate when the system is actively working. Allow the VSC system to operate; avoid abrupt steering or braking inputs.
The VSC system can be temporarily disabled with the “TRAC OFF” switch, but it’s recommended to keep it enabled for optimal safety.
Traction Control (TRAC)
Your 2012 Toyota Highlander features Traction Control (TRAC), a system designed to limit wheel spin during acceleration on low-traction surfaces like snow, ice, or gravel. TRAC works by monitoring wheel speed and reducing engine power or applying braking force to spinning wheels.
A TRAC indicator light on the instrument panel illuminates when the system is actively engaged. It’s generally best to allow TRAC to function automatically; avoid excessive throttle input when the light is flashing.
The TRAC system can be temporarily deactivated using the “TRAC OFF” switch, useful when intentionally rocking the vehicle free if stuck.
Maintenance and Care
Regular maintenance is crucial for your Highlander’s longevity and performance; follow the recommended schedule for optimal reliability and continued safe operation.
Recommended Maintenance Schedule
Maintaining your 2012 Toyota Highlander involves a structured schedule to ensure optimal performance and longevity. Every 5,000 miles (or six months, whichever comes first), inspect and rotate tires, check fluid levels (oil, coolant, brake, power steering, and windshield washer), and visually inspect brakes;
At 15,000 miles, add these services: replace engine air filter, inspect drive belts, and check exhaust system. Every 30,000 miles, replace cabin air filter, inspect fuel lines and connections, and service the automatic transmission fluid. Major services at 60,000 miles include replacing spark plugs and inspecting the cooling system.
Always refer to the detailed maintenance schedule in your owner’s manual for specific intervals and recommendations tailored to your driving conditions.
Fluid Checks (Oil, Coolant, Brake Fluid)
Regularly checking your 2012 Toyota Highlander’s fluids is crucial for preventing damage and ensuring safe operation. Engine oil should be checked weekly, adding the recommended grade if low. Coolant levels, visible in the reservoir, should be maintained between the ‘MIN’ and ‘MAX’ lines when the engine is cold.
Brake fluid, vital for stopping power, must be at the ‘MAX’ level in the master cylinder. Low levels indicate a potential leak. Power steering fluid and windshield washer fluid should also be topped off as needed.
