• Cabin air filter × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and ensure it is powered off
2. Verify vehicle has at least 20% state of charge for accurate diagnostics
3. Connect Rivian Diagnostic Tool (RDT) to OBD-II port located under driver side dashboard
4. Allow vehicle to sit for 10 minutes to normalize battery temperature readings
5. Record current odometer reading and recent energy consumption data from driver display

Procedure

1. 1

   Perform comprehensive vehicle diagnostics
   Using the Rivian Diagnostic Tool, run a complete system scan focusing on Battery Management System (BMS), Thermal Management System, Drive Unit controllers, and Energy Management Module. Review any stored fault codes or efficiency warnings. Document battery capacity degradation percentage and cell voltage variance (should be within 0.02V across all cells).
2. 2

   Verify tire pressures and condition
   Check all four tire pressures when cold. For the EDV 500 with standard load rating, set front tires to 50 PSI and rear tires to 56 PSI (adjust per door placard for specific configuration). Inspect tread depth (minimum 4/32 inch for optimal range) and look for uneven wear patterns indicating alignment issues. Incorrect tire pressure can reduce range by up to 10%.
3. 3

   Inspect brake system for drag
   Raise vehicle if necessary and rotate each wheel by hand to check for binding or excessive drag from brake calipers. EDV brake calipers should release fully when not applied. Check brake pad thickness - excessively worn pads or seized calipers increase rolling resistance. Verify regenerative braking system is functioning via diagnostic tool under 'Drive Unit' menu.
4. 4

   Test 12V battery health
   The 12V lithium-ion battery powers vehicle accessories and computers. Use battery load tester to verify voltage under load (should maintain above 12.5V). A weak 12V battery causes increased draw from the high-voltage system and reduces range. Check for parasitic draws exceeding 50mA with vehicle asleep.
5. 5

   Inspect cabin air filter and HVAC system
   Remove and inspect cabin air filter located behind glove box. A clogged filter forces HVAC system to work harder, consuming more energy. Replace if visibly dirty or restricted. Verify HVAC system operation in diagnostic mode - check for proper airflow distribution and temperature control. HVAC is one of the largest auxiliary power consumers in EVs.
6. 6

   Verify battery thermal management system
   Using diagnostic tool, access Battery Thermal Management menu. Check coolant temperature sensors are reading accurately (compare front and rear module temps - variance should be less than 5°C). Verify thermal management pump operation by commanding pump test. Check coolant level in reservoir located in front cargo area - should be between MIN and MAX marks. Low coolant reduces thermal efficiency.
7. 7

   Inspect drive unit fluid levels
   Check EV transmission fluid level in both front and rear drive units through fill ports. Fluid should be at bottom of fill hole when level. Low fluid increases friction and heat in drive units. Inspect for leaks around drive unit seals and check differential fluid levels if vehicle is equipped with traditional differential components. Do not overfill.
8. 8

   Check wheel alignment and suspension components
   Visually inspect suspension components for worn bushings, ball joints, or tie rod ends that could affect alignment. Misalignment increases rolling resistance significantly. If vehicle pulls to one side or tire wear is uneven, recommend full alignment service. Check that all suspension components are tight and properly seated.
9. 9

   Update vehicle software
   Using RDT, check for available software updates for Battery Management System, Drive Unit Controllers, and Energy Management Module. Rivian regularly releases efficiency optimization updates. Download and install any available updates following Rivian service procedures. Do not interrupt power during update process. Updates can take 30-45 minutes.
10. 10

    Perform battery conditioning cycle
    If diagnostic tool indicates cell imbalance greater than 0.015V, initiate battery balancing procedure through service menu. This process can take 2-4 hours and should be performed with vehicle plugged into charger. Cell balancing ensures all battery cells are at equal voltage, maximizing available capacity and range.
11. 11

    Reset energy consumption metrics
    Clear trip data and energy consumption history through vehicle settings or diagnostic tool. This provides customer with fresh baseline to measure range improvement. Document baseline energy consumption rate (Wh/mi) before reset for comparison after optimization.
12. 12

    Configure vehicle settings for optimal efficiency
    Review and optimize driver-configurable settings: Set regenerative braking to 'Standard' mode, verify Conserve mode is available and explained to customer, disable unnecessary features like always-on WiFi hotspot, set climate pre-conditioning to occur while plugged in. Educate customer on eco-driving practices specific to EDV 500.

Reassembly

1. Reinstall cabin air filter access panel and secure glove box if removed
2. Lower vehicle from lift if raised and torque wheel lug nuts to specification
3. Disconnect diagnostic tool and verify all access panels are properly secured
4. Clear any diagnostic mode flags and return vehicle to normal operation mode

Verification

• Start vehicle and verify all dashboard warning lights are off
• Check that estimated range display is calculating properly based on current state of charge
• Verify HVAC system operates normally with improved airflow if filter was replaced
• Confirm regenerative braking engages smoothly during test drive
• Review diagnostic report with customer showing baseline vs. optimized parameters
• Provide customer with documentation of tire pressures, software versions, and recommended driving practices for maximum range
