01 / This trim
What makes this trim its own car
Position in the lineup
Mid-range trim
- Unique drivetrain: AWD PHEV.
Ideal buyer
Who this trim is for
Owners who'll actually use the capability — tow ratings, payload and off-road hardware are typically the same as the more expensive trims, so the value is high if you don't need the cosmetic upgrades.
Probably not for
Anyone whose use case clearly favours another trim — if you're never going to chase the 0–60 number or the top speed, the cheaper trim makes more financial sense.

04 / Maintenance
Keep it running for the long haul
Plug-in hybrids like the CX-90 PHEV Premium Plus have BOTH an ICE and a high-voltage battery — meaning the most demanding maintenance schedule of any drivetrain. The engine sees short, cold cycles that contaminate oil; the battery needs the same care as a full EV.
Break-in (first 1,000–1,500 mi)
Most powertrain damage happens here. Do these right and the car will outlive its electronics.
- First 600 mi: keep RPM below 4,000 and avoid full-throttle pulls. Vary RPM constantly — no cruise control.
- Avoid highway-speed cruise for >30 min stretches; varied load helps the rings seat properly.
- Do NOT change the factory-fill oil before 1,500 mi unless the manufacturer specifies otherwise — the oil contains break-in additives.
- At 1,500–3,000 mi, perform the first oil change to remove metal break-in particles from ring/bearing seating.
| Interval | Task | Why it matters | Priority |
|---|---|---|---|
| Weekly | Cold tire pressure check | Set to door-jamb spec when tires are cold. Underinflation kills sidewalls and fuel/range economy; overinflation reduces grip. | High |
| Weekly | Visual walk-around | Check for fluid spots on the ground, tire condition, light operation, and any new noises before driving off. | Recommended |
| Monthly | Fluid level audit | Open the hood: check engine oil (where dipstick exists), coolant overflow level, brake fluid, washer fluid, power steering (if hydraulic). | High |
| Monthly | Wash + interior vacuum | Salt, road tar and bird droppings etch paint and clearcoat. Use pH-neutral car shampoo, two-bucket method. | Recommended |
| Every 6 months | Wax / ceramic top-up | Paint protection prevents oxidation. Spray-on ceramic boosters extend a base coat for 6–9 months. | Recommended |
| Every 12 months | Wiper blades + washer fluid | Replace both blades; switch to winter blades + de-icer fluid in cold climates. | Recommended |
| Every 12 months | 12V auxiliary battery test | Load-test the 12V battery — even EVs have one, and a weak 12V causes the most no-starts on modern cars. | High |
| Every 24 months | Brake fluid moisture test | Test with a refractometer or strips. >2% water content = flush. Hygroscopic fluid corrodes ABS modulators. | Critical |
| Every 24 months | Alignment check | Even a curb hit can throw alignment off. Mis-alignment burns through $1k+ tire sets quickly. | High |
| Every 7,500 mi / 12 months | Full-synthetic oil + filter change | Modern long-life synthetic at OEM spec. Don't stretch past the time interval even if low mileage — oil degrades by age too. | Critical |
| Every 30,000–60,000 mi | Coolant level + condition check | Use only the OEM-spec coolant (manufacturer-spec long-life). Mixing coolant types causes gelling and water-pump failure. | High |
| Every 60,000 mi | Coolant flush + refill | Long-life ≠ lifetime. Old coolant turns acidic and eats aluminum heads. | High |
| Every 15,000 mi | Engine air filter + cabin filter | Restricted intake hurts power and economy. Replace cabin filter sooner in pollen-heavy or urban areas. | Recommended |
| Every 60,000–100,000 mi | Iridium / platinum spark plugs | Modern long-life plugs; replace as a complete set with anti-seize. | High |
| Every 100,000 mi | Timing chain / belt service | Most modern engines use chains (inspect tensioner & guides); some Audi 2.0/3.0 TDI/TFSI use a belt that MUST be replaced on schedule — failure destroys the engine. | Critical |
| Every 12 months | Brake pad/rotor visual + caliper slide service | Lubricate caliper slide pins with high-temp grease. Replace pads at 3 mm; rotors at minimum thickness or when scored. | Critical |
| Every 24 months / 30,000 mi | Brake fluid flush (DOT 4 or higher) | OEM-spec DOT 4 fluid; bleed all four corners, ABS module, and clutch (if hydraulic). | Critical |
| Every 30,000 mi | Suspension bushing + ball-joint inspection | Check control-arm bushings, sway-bar end links, tie-rod ends and ball joints for play. Worn bushings cause clunks and uneven tire wear. | High |
| Every 50,000 mi | Power steering fluid (if hydraulic) | Electric racks are sealed-for-life. Hydraulic systems need a fluid flush to prevent pump whine. | Recommended |
| Every 7,500 mi / 12 months | Engine oil + filter (low-mileage rule) | PHEVs accumulate engine 'cold-start' damage because the ICE runs briefly. Change oil on TIME not mileage — moisture from short cycles contaminates oil quickly. | Critical |
| Every 12 months | Run ICE for 20+ min at highway speed | If you drive only on battery, run the engine occasionally to burn off condensation, warm the catalyst, and circulate fuel. | High |
| Every 12 months | Fuel system stabilizer check | Low fuel use → stale gasoline. Top up regularly and use a stabilizer if tank sits >3 months. | High |
| Every 24 months | HV battery cell-balance + state-of-health scan | Dealer scan tool checks individual cell voltages and battery capacity vs new. Catch degraded modules under warranty. | Critical |
| Every 25,000 mi | HV battery coolant inspection | Same as full EV — PHEV packs are smaller but the coolant loop is identical. | High |
| Every 4 years | HV battery coolant flush | Glycol loop on the traction battery; spec'd at 4 yr by most PHEV manufacturers. | High |
| Every 50,000 mi | 12V auxiliary battery (AGM) | PHEVs cycle the 12V harder than ICE because the DC-DC converter only runs when HV is on. AGM batteries last ~4–5 yr. | High |
| Every 30,000–50,000 mi | Automatic transmission fluid + pan filter | 'Lifetime' is marketing — fluid breaks down by 60k. Use exact OEM spec (ZF Lifeguard 8 for 8HP, MB 236.15, etc.). Drop-pan service is gentler than a power flush. | High |
| Every 30,000 mi | Front & rear differential oil | AWD components see constant load. Use OEM 75W-90 or 75W-140 gear oil and friction modifier on LSDs. | High |
| Every 30,000 mi | Transfer case fluid | Transfer case fluid is small in volume but high in shear stress. Replace at every diff service. | High |
| Every 7,500 mi | Performance tire rotation + wear-depth audit | Heavy / high-power cars (5,198 lb, 323 hp) shred rear tires fast. Cross-rotate fronts to opposite rear, keep all four within 2/32" depth. | Critical |
| Before storage (>30 days) | Fuel stabilizer + battery tender + tire pressure +5 psi | Add Sta-Bil to a full tank, hook a smart tender to the 12V (and Level-1 charge any EV/PHEV), inflate tires +5 psi to prevent flat-spotting, leave windows cracked. | High |
| Coming out of storage | Pre-flight inspection | Check tire pressures, brake function (rotors will be surface-rusted — bed gently), fluid levels, and rodent damage in the engine bay and cabin air intake. | High |

| HV battery coolant | Glycol-based (OEM only) — DO NOT mix | — |
| Drive-unit gear oil | OEM low-viscosity (e.g. Tesla 75W) — small fill, sealed | — |
Longevity tips
- Run the engine to full operating temperature at least once a week — short EV-only cycles cause moisture buildup in the oil.
- Top up the fuel tank regularly; stale gasoline (>3 months) deposits varnish in injectors.
- Charge on AC overnight to extend battery life; DC fast-charge sparingly.
- Use OEM oil change interval based on TIME not mileage if you mostly drive electric.
- Have the battery cell-balance scan done annually under warranty.
- Keep a written service log — both for your own tracking and resale value (Carfax-style records add 5–10% at sale).
- Use OEM-spec parts and fluids — aftermarket 'equivalents' often aren't, and brand-engineered specs exist for real reasons.
- Replace tires as a complete set (or at minimum same axle) and never mix tire models on an AWD car — damages the center diff.
Brand-specific notes
- Always cross-reference your VIN with the latest OEM TSBs and recalls — manufacturers fix common issues silently under warranty.
- Use the manufacturer app or a third-party scan tool (BimmerLink, OBDeleven, Techstream, Forscan) to monitor adaptations and clear codes between services.
