Subaru Ascent 2018-2026 Owner's Manual: Maximum load limits

WARNING

Never exceed any of the specified load limits for the Subaru Ascent described in this section.

Operating the Subaru Ascent beyond its maximum load capacity may lead to serious personal injury, compromised vehicle stability, and significant mechanical damage.

CAUTION

• When the combined weight of the trailer and its cargo exceeds 1,000 lbs (453 kg), the use of properly sized and functioning trailer brakes is mandatory for safe towing with the Subaru Ascent.
• Before towing, always verify the total trailer weight, Gross Vehicle Weight (GVW), Gross Axle Weights (GAWs), and tongue load. Ensure that the distribution of weight between the Subaru Ascent and the trailer is balanced and within acceptable limits.

Total trailer weight

Total trailer weight

The total trailer weight—defined as the combined mass of the trailer and all cargo it carries—must never exceed the maximum allowable values specified for the Subaru Ascent in the table below.

*1: Continuously variable transmission type TR690SXXXX (refer to "Vehicle identification" to locate the transmission model label).
*2: Continuously variable transmission type TR690GXXXX (refer to "Vehicle identification" to locate the transmission model label).

Gross Vehicle Weight (GVW) and Gross Vehicle Weight Rating (GVWR)

Gross Vehicle Weight

The Gross Vehicle Weight (GVW) of the Subaru Ascent must always remain within the limits defined by the Gross Vehicle Weight Rating (GVWR).

GVW represents the total combined weight of the Subaru Ascent, including the driver, passengers, luggage, installed accessories, trailer hitch, trailer tongue load, and any additional equipment.

Because these factors vary depending on usage, the GVW of the Subaru Ascent will change accordingly. It is recommended to measure the actual vehicle weight using a certified scale before long trips or when towing heavy loads.

Certification label

The official GVWR specification for your Subaru Ascent is provided on the certification label located at the lower section of the driver’s side door pillar.

Gross Axle Weight (GAW) and Gross Axle Weight Rating (GAWR)

Gross Axle Weight

The Gross Axle Weight (GAW) refers to the load placed on each individual axle of the Subaru Ascent. This value must not exceed the Gross Axle Weight Rating (GAWR) specified by the manufacturer.

Improper load distribution can result in one axle being overloaded even if the total GVW is within acceptable limits. This can negatively impact handling, braking performance, and overall safety.

To maintain optimal performance of the Subaru Ascent, always distribute cargo evenly and avoid concentrating excessive weight at either the front or rear of the vehicle.

Additional note: Respecting all load limits is essential for safe towing and driving with the Subaru Ascent. Proper weight management not only protects critical vehicle components but also ensures stable handling, effective braking, and long-term durability under demanding conditions.

The load applied to each axle of the Subaru Ascent, known as the Gross Axle Weight (GAW), must always remain within the limits defined by the Gross Axle Weight Rating (GAWR). Exceeding these limits can negatively impact handling, braking performance, and overall vehicle safety.

Proper distribution of passengers and cargo inside the Subaru Ascent allows you to balance the front and rear axle loads effectively. Adjust seating positions and luggage placement to maintain optimal weight distribution.

The GAWR values for both the front and rear axles of the Subaru Ascent are listed on the certification label located at the lower portion of the driver’s side door pillar.

To ensure that both GVWR and GAWR limits are respected, and to confirm safe weight distribution when towing, it is highly recommended to weigh your Subaru Ascent and trailer at a certified commercial weighing station.

Always secure all cargo properly to prevent shifting during driving, as movement of loads can alter weight distribution and compromise vehicle stability.

Tongue load

Tongue load

For safe towing with the Subaru Ascent, the trailer tongue load should be maintained between 8% and 11% of the total trailer weight. It must also not exceed the following maximum limits.

• Models equipped with an air-cooled continuously variable transmission fluid cooler: 500 lbs (227 kg)
• Models without an air-cooled continuously variable transmission fluid cooler: 200 lbs (91 kg)

1. Jack
2. Bathroom scale

The tongue load of a trailer connected to the Subaru Ascent can be measured using a standard bathroom scale, as illustrated above. When performing this measurement, ensure that the trailer coupler is positioned at the same height as it would be during actual towing. Use a jack to adjust the height accordingly for accurate results.

6. Front

Proper tongue load is achieved by correctly distributing cargo within the trailer. For optimal stability when towing with the Subaru Ascent, approximately 60% of the total load should be placed toward the front of the trailer, with the remaining 40% positioned toward the rear.

Additionally, weight should be evenly distributed from left to right to maintain balance and prevent uneven stress on the Subaru Ascent suspension and tires.

As with all cargo, ensure that trailer contents are securely fastened to avoid shifting during transit, which could alter load balance and affect handling.

WARNING

If excessive weight is positioned behind the trailer axle rather than in front, the load on the rear axle of the Subaru Ascent will be reduced.

This condition can lead to instability, causing the rear wheels to lose traction, particularly during braking or when slowing in turns. Such imbalance may result in oversteer, trailer sway, or even dangerous jackknifing situations.

Additional note: Maintaining correct tongue load and balanced cargo distribution is critical for safe towing with the Subaru Ascent. Proper setup significantly improves stability, steering response, and braking efficiency, ensuring a safer and more controlled driving experience.
