Troubleshooting and Emergency Procedures
Be Prepared: This section of the 2021 Ram 1500 manual details procedures for jump starts, flat tires, emergency braking, and accident response.
Jump Starting Procedures
Caution is Key: If your 2021 Ram 1500 battery is depleted, a jump start can get you moving again. However, following the correct procedure is crucial to avoid damage to the vehicle’s electrical system. First, ensure both vehicles are turned off. Connect the positive (+) cable to the positive terminal of the discharged battery, then to the positive terminal of the good battery.
Next, connect the negative (-) cable to the negative terminal of the good battery, and finally, to a grounded metal surface on the disabled Ram 1500 – not directly to the negative terminal. Start the vehicle with the good battery, let it run for a few minutes, then attempt to start the Ram 1500. Disconnect the cables in the reverse order of connection.
Refer to your owner’s manual for specific diagrams and safety precautions. Improper jump starting can cause sparks and potential battery explosions, so proceed with care.
Flat Tire Procedures
Safety First: If you experience a flat tire on your 2021 Ram 1500, prioritize safety. Pull over to a level, stable surface away from traffic. Activate your hazard lights. Engage the parking brake firmly. Locate your spare tire, jack, and lug wrench – typically found under the vehicle or in the cargo area.
Before jacking up the vehicle, loosen the lug nuts on the flat tire. Position the jack according to your owner’s manual’s instructions. Raise the vehicle until the flat tire is off the ground. Remove the lug nuts completely and carefully remove the flat tire. Mount the spare tire, tighten the lug nuts by hand, and lower the vehicle.
Once on the ground, fully tighten the lug nuts in a star pattern. Check the spare tire’s pressure and have the flat tire repaired or replaced as soon as possible.
Emergency Braking
Responding to Hazards: In a critical situation requiring immediate stopping with your 2021 Ram 1500, employ emergency braking. Firmly and steadily depress the brake pedal. Avoid pumping the brakes, as this can reduce braking effectiveness. Allow the Anti-lock Braking System (ABS) to activate if it senses wheel lockup – you may feel a pulsating sensation in the pedal.
Maintain firm pressure on the brake pedal even during ABS activation. Steer in the direction you want the vehicle to go while braking; ABS allows steering control during hard braking.
Be aware of road conditions; braking distances increase on slippery surfaces. After an emergency stop, carefully assess the situation before proceeding.
What to Do in an Accident
Post-Collision Steps: Following an accident involving your 2021 Ram 1500, prioritize safety. Check for injuries to yourself and passengers. If possible, move the vehicle to a safe location away from traffic. Activate hazard lights to alert other drivers.
Exchange information with other involved parties, including names, contact details, insurance information, and vehicle registration. Contact local law enforcement to report the accident and obtain a police report.
Document the scene with photos or videos, if safe to do so. Notify your insurance company promptly and follow their instructions for filing a claim.
